  • [Title] Serum protein fingerprinting coupled with artificial neural network distinguishes glioma from healthy population or brain benign tumor.
  • To screen and evaluate protein biomarkers for the detection of gliomas (Astrocytoma grade I-IV) from healthy individuals and gliomas from brain benign tumors by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) coupled with an artificial neural network (ANN) algorithm.
  • SELDI-TOF-MS protein fingerprinting of serum from 105 brain tumor patients and healthy individuals, included 28 patients with glioma (Astrocytoma I-IV), 37 patients with brain benign tumor, and 40 age-matched healthy individuals.
  • An accuracy of 95.7%, sensitivity of 88.9%, specificity of 100%, positive predictive value of 90% and negative predictive value of 100% were obtained in a blinded test set comparing gliomas patients with healthy individuals; an accuracy of 86.4%, sensitivity of 88.9%, specificity of 84.6%, positive predictive value of 90% and negative predictive value of 85.7% were obtained when patient's gliomas was compared with benign brain tumor.
  • The high sensitivity and specificity achieved by the use of selected biomarkers showed great potential application for the discrimination of gliomas patients from healthy individuals and gliomas from brain benign tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Computer-aided detection of brain tumor invasion using multiparametric MRI.
  • PURPOSE: To determine the potential of using a computer-aided detection method to intelligently distinguish peritumoral edema alone from peritumor edema consisting of tumor using a combination of high-resolution morphological and physiological magnetic resonance imaging (MRI) techniques available on most clinical MRI scanners.
  • MATERIALS AND METHODS: This retrospective study consisted of patients with two types of primary brain tumors: meningiomas (n = 7) and glioblastomas (n = 11).
  • Meningiomas are typically benign and have a clear delineation of tumor and edema.
  • Four classifiers of differing designs were trained using morphological, diffusion-weighted, and perfusion-weighted features derived from MRI to discriminate tumor and edema, tested on edematous regions surrounding tumors, and assessed for their ability to detect nonenhancing tumor invasion.
  • Each classifier was able to identify areas of nonenhancing tumor invasion supported with adjunct images or follow-up studies.
  • CONCLUSION: The combination of features derived from morphological and physiological imaging techniques contains the information necessary for computer-aided detection of tumor invasion and allows for the identification of tumor invasion not previously visualized on morphological, diffusion-weighted, and perfusion-weighted images and maps.

  • [Title] Benign adult brain tumors: an evidence-based medicine review.
  • BACKGROUND: Benign adult brain tumors can be managed conservatively or using surgery, radiation, or medicines.
  • While randomized comparisons assessing tumor recurrence, quality of life, or survival are the ideal means of comparing treatments, it can be difficult to recruit patients to such trials and lengthy follow-up periods are needed because of the slowly progressive natural history of these tumors.
  • METHODS: Review of the literature on benign adult brain tumors using evidence-based standards and focusing on meningiomas, pituitary adenomas, and vestibular schwannomas, which together represent the majority of WHO grade 1 adult brain tumors.
  • RESULTS: Nearly all studies of benign adult brain tumors were of relatively poor quality (level 3 or poorer).
  • CONCLUSIONS: While randomized clinical trials comparing conservative management, surgery, radiation, and medical management of benign adult benign tumors are unlikely to occur, there is some level 3 evidence that can assist in their treatment.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Papillary glioneuronal tumor: not always a benign tumor?
  • Papillary glioneuronal tumor (PGNT) is a variant of ganglioglioma, characterized by a pseudopapillary structure with a single pseudostratified layer of small, cuboidal, GFAP-positive cells around hyalinized blood vessels.
  • To date, less than 30 cases have been described with a usually benign course.
  • We report two additional cases: a clinically, radiologically and histopathologically typical tumor in a 38-year-old man and an atypical tumor with histopathological features of anaplasia in a 74-year-old woman.
  • The latter tumor showed the classical pseudopapillary pattern with ganglioid cells and some astrocytes between the papillae, but also had changes suggestive of anaplasia including necrosis, capillary endothelial proliferation, mitoses, dedifferentiation with loss of GFAP expression of the cuboidal cells and increased Ki-67 labeling of over 10%.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [BOLD-fMRI in sensory area and motor hand functional area with brain tumor in the central area].
  • OBJECTIVE: To explore the geomorphological performance, the characteristics of volume, and the largest signal intension of blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI) in brain tumors located in or closed to the central area.
  • METHODS: We recruited 13 normal volunteers and 31(13 benign tumors and 18 malignant tumors) patients with brain tumor located in or closed to the central area, to examine both side hand motor and tactile function by BOLD-fMRI and obtained the activation map and its superposition image with T1 imaging, the volume, and the largest signal intension of the functional area by SPM software which manipulated the raw data in the off-line work station.
  • There was difference in the activated signal pixel number and the largest signal intension of the functional area between the benign brain tumors, malignant brain tumors, and the normal volunteers (P < 0.05).
  • The shape, anatomic location, the volume, and the largest signal intension of the functional area were changed in the patients with brain tumors.
  • CONCLUSION: BOLD-fMRI is a valid method to assess the pre-surgical risk of patients with brain tumors, which can get the volume, the largest signal intension, the basic shape,and the anatomic location of the functional area.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Malignant progression of benign brain tumors after gamma knife radiosurgery: is it really caused by irradiation?
  • Malignant transformation of benign neoplasm after radiosurgery is usually diagnosed based on the initial presence of benign tumor, its exposure to ionizing radiation, elapsed time from radiation exposure to malignant progression, and different histological characteristics or growth rate of the regrowing tumor comparing with those originally treated.
  • Evaluation of the proliferative potential of the benign neoplasm before radiosurgical treatment either directly, if tumor sampling is available, or indirectly, by calculation of the tumor growth rate and/or analysis of the data of the metabolic imaging (PET, MRS) is important for identification of "aggressive" subtypes, precise prediction of prognosis, and confirmation of the radiation-induced malignant transformation in cases of tumor regrowth.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Optimum wavelength for the differentiation of brain tumor tissue using autofluorescence spectroscopy.
  • OBJECTIVE: The role of autofluorescence spectroscopy in the detection and staging of benign and malignant brain tumors is being investigated in this study, with an additional aim of determining an optimum excitation wavelength for the spectroscopic identification of brain tumors.
  • MATERIALS AND METHODS: The present study involves in-vitro autofluorescence monitoring of different human brain tumor samples to assess their spectroscopic properties.
  • The autofluorescence measurement at four different excitation wavelengths 320, 370, 410, and 470 nm, were carried out for five different brain tumor types: glioma, astrocytoma, meningioma, pituitary adenoma, and schwannoma.
  • RESULTS: The fluorescence spectra of tumor tissues showed significant differences, both in intensity and in spectral profile, from those of adjacent normal brain tissues at all four excitation wavelengths.
  • Of the four excitation wavelengths being considered, 470 nm appeared to be the optimal wavelength for detecting tissue fluorescence of brain tumor tissues.
  • CONCLUSIONS: In conclusion, the spectroscopic luminescence measurements carried out in this study revealed significant differences between tumor tissue and adjacent normal tissue of human brains for all the tumor types tested, except for pituitary adenoma.
  • From the results of this study we conclude that excitation wavelengths ranging from 410-470 nm are most suitable for the detection of brain tumor tissue.

  • BACKGROUND: The aim of this study is to analyze the work of the interdisciplinary Brain Tumor Board (BTB) which was established at Freiburg University Hospital in 1998.
  • This group was composed of 4 subgroups: 28% benign skull base tumors (19% meningiomas, 4% pituitary adenomas, 3% acoustic schwannomas, 2% others), 24% primary brain tumors of glial origin (8% glioblastomas, 12% gliomas other than glioblastomas, 5% oligoastrocytomas or oligodendrogliomas), 19% brain metastases, and 8% other brain or skull base tumors.
  • CONCLUSION: Interdisciplinary care seems to be particularly necessary in patients with benign skull base tumors, gliomas and brain metastases.

  • [Title] Benign and atypical meningioma metabolic signatures by high-resolution magic-angle spinning molecular profiling.
  • Meningiomas are neoplasms that arise from the leptomeningeal covering of the brain and spinal cord, accounting for 15%-20% of CNS tumors.
  • The WHO classifies meningiomas into three histological grades: benign, atypical, and anaplasic in accordance with the clinical prognosis.
  • Sometimes, meningiomas with histological diagnosis of benign meningioma show clinical characteristics of atypical meningioma.
  • In this context, high-resolution magic-angle spinning (HR-MAS) spectroscopy of intact tissue from brain tumor biopsies has shown great potential as a support diagnostic tool.
  • In this work, we show differences between benign and atypical meningiomas in HR-MAS molecular profiles of meningioma biopsies.
  • Glutamine and glutamate, which are related to glutathione metabolism and have been associated with tumor recurrence, are also increased in atypical meningiomas.
  • Other metabolites associated with tumor malignancy that show statistically significant differences between benign and atypical meningiomas include phosphocholine and phosphoethanolamine.
  • Overall, this work suggests that the additional information obtained by NMR metabolomics applied to biopsies of human meningiomas may be useful for assessing tumor grade and determining optimum treatment strategies.

  • Brain is considered abnormally sensitive to oxidative damage as brain tissue has high rate of oxygen consumption, high lipid content and relatively low antioxidant defenses, compared to other tissues.
  • RESULTS: The mean values of salivary flow rate and pH were significantly decreased among malignant and benign tumor patients whereas the salivary osmolality was significantly increased in both the groups of patients.
  • The mean values of salivary FRAP were significantly reduced among malignant and benign tumor patients.
  • CONCLUSION: Hence with these observations it can be concluded that in saliva, besides the physical characteristics, salivary FRAP and protein thiol levels are appropriate indicators of the antioxidant status in brain tumor patients.

  • [Title] Early recurrences in histologically benign/grade I meningiomas are associated with large tumors and coexistence of monosomy 14 and del(1p36) in the ancestral tumor cell clone.
  • Tumor recurrence is the major clinical complication in meningiomas, and its prediction in histologically benign/grade I tumors remains a challenge.
  • In this study, we analyzed the prognostic value of specific chromosomal abnormalities and the genetic heterogeneity of the tumor, together with other clinicobiological disease features, for predicting early relapses in histologically benign/grade I meningiomas.
  • A total of 149 consecutive histologically benign/grade I meningiomas in patients who underwent complete tumor resection were prospectively analyzed.
  • Similarly, histologically benign/grade I meningiomas showing coexistence of monosomy 14 and del(1p36) in the ancestral tumor cell clone displayed a higher frequency of early relapses.
  • In fact, coexistence of -14 and del(1p36) in the ancestral tumor cell clone, together with tumor size, represented the best combination of independent prognostic factors for the identification of those patients with a high risk of an early relapse.
  • Our results indicate that patients with large histologically benign/grade I meningiomas carrying monosomy 14 and del(1p36) in their ancestral tumor cell clone have a high probability of relapsing early after diagnostic surgery.

  • OBJECT: The authors report the effects of Gamma Knife surgery (GKS) on benign tumor-related trigeminal pain in patients who underwent follow-up for a mean 57.8 months.
  • METHODS: From 1999 to 2004, 21 patients with benign tumor-related trigeminal pain (12 meningiomas and 9 schwannomas) underwent GKS as a primary or repeated treatment.
  • For meningiomas, the mean radiosurgical treatment volume was 8.2 ml (range 1.1-21 ml), and the mean radiosurgical tumor margin dose was 12.7 Gy (range 12-15 Gy); for schwannomas, the mean volume was 5.6 ml (range 2-9.2 ml), and the mean marginal dose was 13 Gy (range 11.5-16 Gy).
  • For all 21 patients (100%), control of tumor growth was documented at a mean of 46 months after GKS.
  • CONCLUSIONS: Gamma Knife surgery appears to be an effective tool to treat benign tumor-related trigeminal pain and control tumor growth.

  • [Title] Perfusion MR imaging for differentiation of benign and malignant meningiomas.
  • INTRODUCTION: Our purpose was to determine whether perfusion MR imaging can be used to differentiate benign and malignant meningiomas on the basis of the differences in perfusion of tumor parenchyma and/or peritumoral edema.
  • METHODS: A total of 33 patients with preoperative meningiomas (25 benign and 8 malignant) underwent conventional and dynamic susceptibility contrast perfusion MR imaging.
  • Maximal relative cerebral blood volume (rCBV) and the corresponding relative mean time to enhance (rMTE) (relative to the contralateral normal white matter) in both tumor parenchyma and peritumoral edema were measured.
  • The independent samples t-test was used to determine whether there was a statistically significant difference in the mean rCBV and rMTE ratios between benign and malignant meningiomas.
  • RESULTS: The mean maximal rCBV values of benign and malignant meningiomas were 7.16+/-4.08 (mean+/-SD) and 5.89+/-3.86, respectively, in the parenchyma, and 1.05+/-0.96 and 3.82+/-1.39, respectively, in the peritumoral edema.
  • The differences in rCBV and rMTE values between benign and malignant meningiomas were not statistically significant (P>0.05) in the parenchyma, but both were statistically significant (P<0.05) in the peritumoral edema.
  • Measurement of maximal rCBV and corresponding rMTE values in the peritumoral edema is useful in the preoperative differentiation between benign and malignant meningiomas.

  • [Title] Distinctive pattern of cannabinoid receptor type II (CB2) expression in adult and pediatric brain tumors.
  • The efficacy of cannabinoids against high-grade glioma in animal models, mediated by two specific receptors, CB1 and CB2, raised promises for targeted treatment of the most frequent and malignant primary brain tumors.
  • Unlike the abundantly expressed CB1, the CB2 receptor shows a restricted distribution in normal brain.
  • Although brain tumors constitute the second most common malignancy in children and the prevalence of histological types of brain tumors vary significantly between the adult and pediatric populations, cannabinoid receptor expression in pediatric tumors remains unknown.
  • In the present study, we compared the expression of the CB2 receptor in paraffin-embedded sections from primary brain tumors of adult and pediatric patients.
  • Most glioblastomas expressed very high levels of CB2 receptors and the expression correlated with tumor grade.
  • Interestingly, some benign pediatric astrocytic tumors, such as subependymal giant cell astrocytoma (SEGA), which may occasionally cause mortality owing to progressive growth, also displayed high CB2 immunoreactivity.
  • In contrast, all examined cases of embryonal tumors (medulloblastoma and S-PNET), the most frequently diagnosed malignant brain tumors in childhood, showed no or trace CB2 immunoreactivity.
  • Our results suggest that the CB2 receptor expression depends primarily on the histopathological origin of the brain tumor cells and differentiation state, reflecting the tumor grade.

  • [Title] Gamma knife radiosurgery for benign tumors with symptoms from brainstem compression.
  • PURPOSE: This study evaluated the role of radiosurgery in the management of symptomatic patients with brainstem compression from benign basal tumors.
  • METHODS AND MATERIALS: Over a 17-year, period 246 patients (202 vestibular schwannomas and 44 meningiomas) with brainstem compression from benign skull-base tumors were managed with Gamma Knife radiosurgery.
  • Median tumor volumes were 3.9 cm(3) (range, 0.8-39.0 mL) and 6.6 mL (range, 1.6-25.1 mL) for vestibular schwannomas and meningiomas, respectively.
  • Patients were categorized into four groups on the basis of the tumor-brainstem relationship on neuroimaging.
  • The tumor control rate was 100 % for meningioma and 97% for vestibular schwannomas (although 5% required an additional procedure such as a ventriculoperitoneal shunt).
  • Balance improved significantly in patients who had less tumor compression (p = 0.0357) after radiosurgery.
  • CONCLUSION: Radiosurgery is a minimally invasive option for patients with benign basal tumors that indent or distort the brainstem.
  • A high tumor growth control rate and satisfactory rate of neurological preservation and symptom control can be obtained with radiosurgery.

  • Statistically significant (P<.001) diminished levels of beta-carotene, beta-tocopherol, SOD and GPx, were observed in all the brain tumor patients as compared to controls.
  • Malignant tumor also showed a relative decrease in antioxidant levels as compared to benign tumors.
  • Comparison of histopathological sections of brain tumors also suggested a inverse relationship between antioxidant level and grades of malignancy.
  • Marked decrease in antioxidant levels may have a role in genesis of considerable oxidative stress in brain tumors.
  • Furthermore, the degree of decline in antioxidant levels may indicate severity of malignancy in brain tumors.

  • [Title] A tumor-specific cellular environment at the brain invasion border of adamantinomatous craniopharyngiomas.
  • Craniopharyngiomas (CP) are benign epithelial tumors of the sellar region and can be clinicopathologically distinguished into adamantinomatous (adaCP) and papillary (papCP) variants.
  • Both subtypes are classified according to the World Health Organization grade I, but their irregular digitate brain infiltration makes any complete surgical resection difficult to obtain.
  • Herein, we characterized the cellular interface between the tumor and the surrounding brain tissue in 48 CP (41 adaCP and seven papCP) compared to non-neuroepithelial tumors, i.e., 12 cavernous hemangiomas, 10 meningiomas, and 14 metastases using antibodies directed against glial fibrillary acid protein (GFAP), vimentin, nestin, microtubule-associated protein 2 (MAP2) splice variants, and tenascin-C.
  • Furthermore, the outer tumor cell layer of adaCP showed a distinct expression of MAP2, a novel finding helpful in the differential diagnosis of epithelial tumors in the sellar region.
  • Our data support the hypothesis that adaCP, unlike other non-neuroepithelial tumors of the central nervous system, create a tumor-specific cellular environment at the tumor-brain junction.

  • A small population of TSCs, which form neurospheres and possess the capacity for self-renewal, has been recently identified in adult and pediatric brain tumors.
  • The understanding of brain TSCs has been greatly advanced by the knowledge of cell proliferation, which contributes to initiate and sustain the malignant phenotype.
  • In this article, the authors summarized the evidence of the presence of TSCs in human brain tumors and emphasized the significance of the proliferative status of TSCs.
  • Finally, the preliminary evidence that TSCs in malignant brain tumors have more proliferative capacity than stem/progenitor cells in benign brain tumors was discussed.

  • [Title] Multisession cyberknife stereotactic radiosurgery of large, benign cranial base tumors: preliminary study.
  • OBJECTIVE: Although radiosurgery plays an important role in managing benign cranial base lesions, the potential for increased toxicity with single-session treatment of large tumors is a concern.
  • METHODS: Between 1999 and 2008, 34 consecutive patients with large (>15 cm), benign cranial base tumors (21 meningiomas, 9 schwannomas, 4 glomus jugulare tumors) underwent primary or postoperative radiosurgical treatment using a multisession approach at Stanford University and were considered in this retrospective study.
  • CyberKnife radiosurgery was delivered in 2 to 5 sessions (median, 3 sessions) to a median tumor volume of 19.3 cm (range, 15.8-69.3 cm).
  • CONCLUSION: Over our modest length of follow-up, multisession radiosurgery appears to be a safe and effective option for selected large, benign brain and cranial base lesions.

  • People with neurofibromatosis 1 (NF1) have multiple benign neurofibromas and a 10% lifetime risk of developing malignant peripheral nerve sheath tumors (MPNSTs).
  • Most MPNSTs develop from benign plexiform neurofibromas, so the burden of benign tumors may be a risk factor for developing MPNST.
  • We studied 13 NF1 patients with MPNSTs and 26 age- and sex-matched controls (NF1 patients who did not have MPNSTs) with detailed clinical examinations and whole-body MRI to characterize their body burden of internal benign neurofibromas.

  • OBJECT: Oncocytic meningioma has recently been recognized as a distinct morphological variant of intracranial meningothelial neoplasms, and only a few cases have been reported in the literature.
  • The first description of this lesion, which was based on data in six cases, revealed a potentially aggressive nature with a tendency to infiltrate the brain and to recur.
  • Mitosis was also absent or exceedingly rare, and no brain cortex infiltration was observed.
  • At the last follow-up evaluation, all patients were asymptomatic and magnetic resonance imaging examinations demonstrated no evidence of tumor recurrence.
  • In fact, the histological features as well as the long-term favorable clinical course may suggest benign behavior of such neoplasms, as in the common forms of meningiomas.

  • [Title] Secretory meningiomas: a benign subgroup causing life-threatening complications.
  • While meningiomas are known as slow-growing extracerebral neoplasms, the subgroup of secretory meningiomas with histologically benign characteristics tend to cause disproportional peritumoral edema, frequently leading to severe medical and neurological complications in postoperative management.
  • The clinical course, radiological appearance, and histopathological features were retrospectively analyzed to examine the specifics of these benign lesions.
  • A severe, nearly hemispheric perifocal edema disproportional to tumor size was seen on preoperative MR imaging in 18 (41%) patients.
  • An association between the extent of brain edema and number of periodic acid Schiff-positive pseudopsammomas was found (p < 0.02).
  • Mean MIB-1 (Ki-67 antigen) proliferation index was 3.0% (range, 0%-17%) and did not correlate with edema or tumor recurrence.

  • [Title] Prospective assessment of quality of life in adult patients with primary brain tumors in routine neurooncology practice.
  • The aim of this article is to evaluate and assess the impact of various factors on quality of life (QOL) in adult patients with primary brain tumors seen consecutively in routine neurooncology practice.
  • Two hundred and fifty-seven adult patients, after undergoing surgical intervention and histologically proven primary brain neoplasms were registered in the NeuroOncology Clinic at our centre during 1 full calendar year.
  • The study included detailed neurological assessment, evaluation of QOL using EORTC questionnaire (QLQ-30) and specific Brain Cancer module (BN 20).
  • In the present analysis, QOL scores before starting adjuvant treatment were measured and impact of patient and tumor related factors were analyzed.
  • Baseline global QOL data of all patients (available in 243) was relatively low including in all histological tumor types.
  • Patients with lower performance status (KPS < 70) had a lower global QOL (KPS >or= 80 vs. <or= 70; 37 vs. 67; p = 0.001) including in all histological types of high-grade gliomas (HGG) (p = 0.005), low-grade gliomas (LGG) (p = 0.04) and benign tumors (p = <0.001).
  • Tumor type is an important patient related factor that influences baseline global scores (LGG vs. HGG 62 and 52; p = 0.015).
  • Type of surgery (biopsy/complete excision) (p = 0.284) and site of tumor (p = 0.309) did not show any impact on QOL score.
  • Patients with primary brain tumours before starting adjuvant therapy have relatively low baseline quality of life scores, especially in lower economic and literacy strata.

  • Several studies have proven its efficiency in detection and localization of tumors of the breast, larynx, thyroid, parathyroid glands, lung, brain, skin, lymphatic and musculoskeletal tissues with a sensitivity and specificity of 95% to 100%.
  • Nevertheless, benign pathology such as active inflammation is a source of false positives and the attending physician must consider the aid of complementary studies such as histopathology.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Long-term follow-up for brain tumor development after childhood exposure to ionizing radiation for tinea capitis.
  • Ionizing radiation is an established risk factor for brain tumors, yet quantitative information on the long-term risk of different types of brain tumors is sparse.
  • Our aims were to assess the risk of radiation-induced malignant brain tumors and benign meningiomas after childhood exposure and to investigate the role of potential modifiers of that risk.
  • The mean estimated radiation dose to the brain was 1.5 Gy.
  • Survival analysis using Poisson regression was performed to estimate the excess relative and absolute risks (ERR, EAR) for brain tumors.
  • After a median follow-up of 40 years, an ERR/Gy of 4.63 and 1.98 (95% CI = 2.43-9.12 and 0.73-4.69) and an EAR/Gy per 10(4) PY of 0.48 and 0.31 (95% CI = 0.28-0.73 and 0.12-0.53) were observed for benign meningiomas and malignant brain tumors, respectively.
  • The estimated ERR/Gy for malignant brain tumors decreased with increasing age at irradiation from 3.56 to 0.47 (P = 0.037), while no trend with age was seen for benign meningiomas.
  • The ERR for both types of tumor remains elevated at 30-plus years after exposure.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Comparison of trace elements in the scalp hair of malignant and benign breast lesions versus healthy women.
  • Trace elements including Al, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sb, Sr, and Zn were analyzed in the scalp hair samples of women with malignant breast lesions, women with benign breast lesions, and healthy donors using atomic absorption spectrophotometric method.
  • In the scalp hair of malignant-tumor patients, the highest average concentration was shown by Ca (1,187 microg/g), followed by Na (655 microg/g), Mg (478 microg/g), Zn (391 microg/g), Sr (152 microg/g), Fe (114 microg/g), and K (89.8), while in the case of benign-tumor patients, the average estimated element levels were 1,522, 1,093, 572, 457, 217, 80.4, and 74.7 microg/g, respectively.
  • Average levels of Na, Sr, K, Cd, Co, Pb, Mg, Ca, Zn, Ni, Sb, and Mn were revealed to be significantly higher in the hair of malignant and benign patients compared to the healthy women; however, Fe, Cu, Al, and Cr were not significantly different in the scalp hair of the three groups.
  • The quartile distributions of Ca, Cd, Co, Cr, K, Mg, Mn, Na, Ni, Pb, Sb, and Sr revealed maximum spread in the scalp hair of malignant and benign groups; nevertheless, Al, Cu, Fe, and Zn exhibited almost comparable quartile levels in the three groups.
  • Strong correlation coefficients were found between Fe and Cd, Al and Na, Mn and Sr, Co and Cr, Cd and Cr, Pb and K, Pb and Mn, Cu and Na, and Al and Fe in the scalp hair of malignant-tumor patients, while Fe and K, Cd and Co, Na and Co, and Cr and Pb showed strong correlations in the scalp hair of benign-tumor patients, both of which were significantly different compared with the healthy subjects.
  • Multivariate cluster analysis also revealed divergent clustering of the elements in the scalp hair of malignant and benign patients in comparison with the healthy women.

  • [Title] Aggressive orbital optic nerve meningioma with benign microscopic features: a case report.
  • Primary optic nerve meningiomas occur at lower ages than meningiomas arising from the coverings of the brain and spinal cord.
  • The patient had a history of orbital meningioma from 10 years ago and several surgical resections due to tumor recurrence during these 10 years.
  • Fine-needle aspiration cytology of the mass confirmed tumor recurrence.
  • The patient first received radiotherapy due to the inoperable mass, and the tumor was resected 1.5 month later.
  • The interesting aspect of this case was the aggressive behavior of the tumor with intraocular invasion, despite its benign histopathological features, which led to wide exenteration of the eye together with resection of the upper and lower lids.

  • [Title] Gender difference in relation to depression and quality of life among patients with a primary brain tumor.
  • OBJECTIVE: We studied the relationship between depressive symptoms and quality of life (QOL) as well as functional status in primary brain tumor patients at recurrent measurements.
  • Differences in QOL between depressive and non-depressive samples by gender were controlled for tumor characteristics and patients' psychosocial factors.
  • MATERIALS AND METHODS: The data consisted of 77 patients with a primary brain tumor, 30 males and 47 females.
  • Depression of the patients was assessed by Beck Depression Inventory (BDI) and Crown-Crisp Experiential Index (CCEI), functional status by Karnofsky Performance scale (KPS) and QOL by Sintonen's 15D before tumor operation as well as at 3 months and at 1 year from surgical operation of the tumor.
  • Depressive patients with a benign brain tumor had significantly worse QOL versus non-depressive ones.
  • DISCUSSION AND CONCLUSION: Decreased QOL was strongly related to depression, especially among patients with a benign brain tumor.

  • [Title] Metastasis of a histologically benign choroid plexus papilloma: case report and review of the literature.
  • Cerebrospinal metastases of benign choroid plexus papillomas (CPPs) are extremely rare.
  • Plain CT scan of the cranium revealed a partly calcified tumor filling the fourth ventricle and its right recess.
  • Cranial MRI showed an inhomogeneously contrast-enhancing tumor and leptomeningeal enhancement encasing the brain stem.
  • Complete resection of the tumor was carried out, and seedings to the floor of the fourth ventricle and cervico-medullary junction were found during the operation.
  • While intraoperative frozen section suggested pathology of papillary ependymoma or CPP, to our surprise, final histological examination revealed a benign choroid plexus papilloma.
  • Two months after the first operation, on follow-up MRI of the cranium, the leptomeningeal enhancement encasing the brain stem had resolved spontaneously.
  • This special case helps increase our understanding of benign CPPs and expands our differential diagnostic consideration of lesions with similar manifestations.

  • [Title] Vessel tortuosity and brain tumor malignancy: a blinded study.
  • Characteristic vessel tortuosity abnormalities appear early during tumor development, affect initially healthy vessels, spread beyond the confines of tumor margins, and do not simply mirror tissue perfusion.
  • MATERIALS AND METHODS: The regional vasculature of 34 healthy subjects was compared with the tumor-associated vasculature of 30 brain tumors before surgical resection.
  • Vessels were segmented from an MRA of each subject, a region of interest was defined in each tumor patient and was mapped to all healthy controls, and a statistical analysis of vessel shape measures was then performed over the region of interest.
  • Many difficult cases were included, such as pinpoint, hemorrhagic, and irradiated tumors, as were hypervascular benign tumors.
  • Tumors were identified as benign or malignant on the basis of histological evaluation.
  • RESULTS: A discriminant analysis performed at the study's conclusion successfully classified all but one of the 30 tumors as benign or malignant on the basis of vessel tortuosity.

  • [Title] Depression in relation to survival among neurosurgical patients with a primary brain tumor: a 5-year follow-up study.
  • In a 5-year follow-up study, we investigated the association of depression with survival of patients with a primary brain tumor.
  • METHODS: The study population consisted of 75 patients with a solitary primary brain tumor treated surgically at the Oulu Clinic for Neurosurgery, Oulu University Hospital, in Northern Finland.
  • The patients were interviewed during admission to the hospital for the tumor surgery.
  • Information on all deaths within 60 months after tumor operation was collected from the Cause of Death Register, provided by Statistics Finland.
  • RESULTS: The patients with a high-grade glioma had a survival time of 22.5 months (standard deviation, 21.4 mo), whereas the corresponding time was 50.2 months (standard deviation, 19.9 mo) for patients with a low-grade glioma and 58.2 months (standard deviation, 9.4 mo) for the patients with a histologically benign tumor (P < 0.001, difference between groups, Kruskal-Wallis test).
  • A corresponding difference was not found in patients with high-grade gliomas or benign tumors.
  • Tumor location in one hemisphere compared with bilateral location and wider extent of tumor surgery was associated with better survival in patients with low-grade gliomas and benign tumors but not in patients with high-grade gliomas.
  • In clinical practice, an evaluation of depression among brain tumor patients by structured and standardized diagnostic methods is needed to distinguish the patients whose depression actually needs treatment.
  • The effective treatment of clinical depression among brain tumor patients and the impact of treatment on the patients' chances of survival should be a focus of future research.

  • [Title] Overexpression of ERBB-2 was more frequently detected in malignant than benign pheochromocytomas by multiplex ligation-dependent probe amplification and immunohistochemistry.
  • To analyze the genetic alterations of pheochromocytomas and evaluate the difference among malignant, extra-adrenal, and benign pheochromocytomas.
  • Forty-three tumor samples were tested for genetic changes using multiplex ligation-dependent probe amplification.
  • All 43 patients (24 women and 19 men; mean age 44.6+/-13.6 years; range 18-75 years; 9 with malignant, 7 extra-adrenal, and 27 benign) showed multiple copy number losses or gains.
  • The average copy number change was 13.10 in malignant, 13.93 in benign, and 13.47 in paraganglioma patients.
  • However, we discovered that in the malignant pheochromocytomas, 6 of the 9 patients (67%) showed erythroblastic leukemia viral oncogene homolog 2 (ERBB-2) oncogene gain, whereas only 12 of the 34 (35%) identified change in the benign and extra-adrenal pheochromocytomas.
  • Further, IHC confirmed that ERBB-2-positive staining was more frequent and stronger in malignant pheochromocytomas than in benign and extra-adrenal pheochromocytomas.
  • The results suggest that there may be certain progression of genetic events that involves chromosomes 1p, 3p, 6p, 11q, 12q, 17q, and 19q in the development of pheochromocytomas, and the activation of ERBB-2 located on chromosome 17q is an important and early event in the malignancy development of these tumor types.

  • [Title] Acoustic neuromas following childhood radiation treatment for benign conditions of the head and neck.
  • Childhood radiation exposure has been associated with an increased risk for developing several neoplasms, particularly benign and malignant thyroid tumors, but little is known about the risk of developing acoustic neuromas.
  • Forty-three patients developed benign acoustic neuromas, forty of them surgically resected, far in excess of what might be expected from data derived from brain tumor registries.
  • Although acoustic neuromas are usually benign and often asymptomatic, many cause significant morbidity.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Correspondence of tumor localization with tumor recurrence and cytogenetic progression in meningiomas.
  • OBJECTIVE: Meningiomas are mostly benign tumors that originate from the coverings of the brain and spinal cord.
  • METHODS: Statistical analyses were performed for the karyotypes of 661 meningiomas with respect to localization, progression, and recurrence of the tumor.
  • A mathematical mixture model estimates typical pathogenetic routes in terms of the accumulation of somatic chromosome changes in tumor cells.
  • The model generates a genetic progression score (GPS) that estimates the prognosis as related to the cytogenetic properties of a given tumor.
  • This corresponds to a total rate of recurrence of 8.0% after macroscopically complete tumor extirpation.
  • Higher GPS values were shown to be strongly correlated with tumor recurrence (P = 2.9 x 10(-7)).
  • High-risk tumors, both in terms of histology and cytogenetics, are localized much more frequently at the brain surface than at the cranial base (P = 1.2 x 10(-5) for World Health Organization grade and P = 3.3 x 10(-12) for GPS categorization).

  • Neuropathologic examination revealed the presence of a gemistocytic cell component (PFS, P = .025), a lack of protein droplets (OS, P = .04; PFS, P = .05), and focal tumor cell-associated CD34 immunolabeling (OS, P = .03) as significant predictors of an adverse clinical course.

  • [Title] Evaluation of primary brain tumors with FLT-PET: usefulness and limitations.
  • PURPOSE OF THE REPORT: The purpose of this report was to investigate the potential of positron emission tomography using F-18 fluorodeoxythymidine (FLT-PET) in evaluating primary brain tumors.
  • MATERIALS AND METHODS: FLT-PET was performed in 25 patients with primary brain tumors.
  • FLT uptake in the lesion was semiquantitatively evaluated by measuring the maximal standardized uptake value (SUVmax) and the tumor-to-normal tissue ratio (TNR).
  • RESULTS: FLT uptake in normal brain parenchyma was very low, resulting in the visualization of brain tumors with high contrast.
  • Both SUVmax and TNR significantly correlated with the malignant grade of brain gliomas, in which high SUVmax/TNR was obtained for high-grade gliomas.
  • CONCLUSIONS: FLT-PET can be used to evaluate the malignant grade and proliferation activity of primary brain tumors, especially malignant brain tumors.
  • However, the presence of benign lesions showing blood-brain barrier disruption cannot be distinguished from malignant tumors and needs to be carefully evaluated.

  • [Title] The Austrian Brain Tumour Registry: a cooperative way to establish a population-based brain tumour registry.
  • In Austria, registration of malignant brain tumours is legally mandatory, whereas benign and borderline tumours are not reported.
  • The Austrian Brain Tumour Registry (ABTR) was initiated under the auspices of the Austrian Society of Neuropathology for the registration of malignant and non-malignant brain tumours.
  • All Austrian neuropathology units involved in brain tumour diagnostics contribute data on primary brain tumours.
  • In 2005, we registered a total of 1,688 newly diagnosed primary brain tumours in a population of 8.2 million inhabitants with an overall age-adjusted incidence rate of 18.1/100,000 person-years.
  • Comparison with the Central Brain Tumor Registry of the United States (CBTRUS) database showed high congruency of findings.
  • The ABTR model led by neuropathologists in collaboration with epidemiologists and the Austrian National Cancer Registry presents a cooperative way to establish a population-based brain tumour registry with high quality data.
  • The continued operation of ABTR will aid in monitoring changes in incidence and in identifying regional disease clusters or geographic variations in brain tumour morbidity/mortality.

  • [Title] Rapid recurrence and malignant transformation of pilocytic astrocytoma in adult patients.
  • In general, surgical resection for pilocytic astrocytoma is thought to be curative with tumor recurrence or malignant transformation being relatively rare.
  • However, there have been very few studies specifically looking at the prognosis for adult patients diagnosed with pilocytic astrocytoma.
  • To evaluate the frequency of recurrence and malignant transformation of pilocytic astrocytoma in adults, we performed a retrospective analysis of all adult patients who underwent surgical resection for this tumor at our institution over a period of 10 years.
  • This study provides further evidence that the clinical course of a subset of adult patients with pilocytic astrocytoma will not be benign.
  • The potential for rapid tumor recurrence and malignant transformation necessitates careful post-operative follow-up for adult patients with this tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Positron emission tomography elucidates transport system and tumor proliferation in meningiomas.
  • To test the in vivo transport system and tumor proliferation of meningiomas, in comparison with gliomas, 25 patients with meningiomas and 8 gliomas underwent quantitative kinetic analysis of ([18F])fluoro-2-deoxy-D-glucose (FDG) - positron emission tomography (PET) imaging and immunohistochemical study.
  • Surgical specimens were evaluated by means of three different methods: i) immunoreactivity to vascular endothelial growth factor (VEGF) and glucose transporter-1 (Glut-1), representing the permeability of tumor vessels;.
  • K1 was higher in meningiomas than in gliomas and was higher in atypical than in benign meningiomas. k3 was correlated with MIB-1 LI in meningiomas, but not in gliomas.
  • Immunohistochemically, meningiomas were less reactive to VEGF or Glut-1 than gliomas but atypical meningiomas stained more intensely than benign meningiomas.
  • The vascular surface area was significantly larger in meningiomas than in gliomas and atypical meningiomas had high values for both permeability and surface area than benign meningiomas.
  • High values for K1 and k3 indicate the aggressive proliferation of meningiomas and, in atypical meningiomas, the synergistic interaction of the high permeability and the large surface area yielded conditions conducive to glucose metabolism and tumor proliferation.
  • Evaluation of K1 and k3 facilitates to predict the tumor aggressiveness and to optimize the surgical management.

  • [Title] Alteration of serum and tumoral neural cell adhesion molecule (NCAM) isoforms in patients with brain tumors.
  • We studied by Western blot the pattern of serum NCAM bands in patients with gliomas (n = 34), with brain metastasis of different primary cancers (n = 27) and with benign brain tumors (n = 22)] compared with healthy controls (n = 69).
  • A similar pattern was found in patients with brain metastasis or brain benign tumors, suggesting that the pattern of serum NCAM bands would be useful to detect brain tumor pathology.
  • Interestingly, we found that 9/12 patients with glioma showed a significant decrease in NCAM HMW/LMW ratio between 1-3 months after successful tumor removal.

  • [Title] Analysis of the expression profile of Dickkopf-1 gene in human glioma and the association with tumor malignancy.
  • BACKGROUND: Gliomas represent the most common primary malignant brain tumors, yet little is known about the molecular pathogenesis of these tumors.
  • The aim of this study was to examine the expression profile of DKK-1 gene in human glioma and its association with tumor malignancy.
  • A total of 47 tumor biopsy specimens and 11 normal brain tissue samples from patients with cerebral trauma internal decompression were embedded in paraffin blocks and used for immunostaining.
  • Twenty-six primary tumors and 7 corresponding brain samples were stored in liquid nitrogen and used for RT-PCR.
  • RESULTS: DKK-1 could only be detected in 12 human glioblastoma cell lines, not in a panel of other tumor and normal cell lines.
  • Kendall's tau-c association analysis also revealed the increased DKK-1 protein expression in tumor tissues of higher pathologic classification.
  • The levels of cerebral fluid DKK-1 protein were significantly higher in glioma patients than in healthy donors or in neuronal benign tumor patients, suggesting that the DKK-1 molecule in cerebral fluids can be applicable to detect the presence of glioma and be developed as a novel prognostic treatment.

  • [Title] Gene expression profiles of meningiomas are associated with tumor cytogenetics and patient outcome.
  • Cytogenetic analysis is a powerful tool for predicting recurrence in meningiomas, even among histologically benign/grade I tumors.
  • Despite this, no study has been reported in which the impact of tumor cytogenetics on the gene expression profiles (GEP) has been analyzed in meningiomas.
  • Accordingly, based on the expression of 85 genes (40 of which were coded in the altered chromosomes used for patient stratification) the cytogenetic class of the tumor could be predicted with an error of <1%, a clear association being found between the GEP and patient outcome (P = 0.03) but not tumor histopathology.

  • BACKGROUND AND PURPOSE: [(11)C]Methionine (MET) PET imaging is a sensitive technique for visualizing primary brain tumors and recurrence/progression after therapy.
  • METHODS: Cerebral uptake of MET was determined in 52 patients: in 26 patients for primary staging (group A) and 26 patients with suspected brain tumor recurrence/progression after therapy (group B).
  • Semiquantitative methionine uptake indices (UI) defined by the tumor (maximum)-to-background ratio was correlated with tumor grade and final outcome.
  • Although a weak linear correlation between MET uptake and grading was observed (R = 0.38, P = .028), analysis of variance showed no significant differences in MET UI between tumor grades for either group A or B.
  • Benign and grade I lesions showed significant difference in MET uptake in comparison with higher grade lesions (P = .006).
  • Moreover, there is no significant prognostic value in studying maximal methionine UI in brain tumors.

  • [Title] Influence of interleukin-6 on the development of peritumoral brain edema in meningiomas.
  • OBJECT: Peritumoral brain edema (PTBE) is associated with perioperative neurological deficits in patients with meningiomas.
  • METHODS: Thirty-six benign meningiomas obtained in 36 patients were studied retrospectively.
  • RESULTS: Peritumoral brain edema was found in 16 patients (44%).
  • Neither age, sex, histological subtype, nor tumor location were related to PTBE.
  • On immunohistochemical analysis, IL-6 protein was found localized in the cytoplasm of the tumor cells, and was detected in 12 (75%) of 16 cases of edematous meningiomas, but in only 6 (30%) of 20 nonedematous cases.
  • CONCLUSIONS: The authors' results in this study indicate that IL-6 expression may contribute to the development of brain edema associated with meningiomas.

  • [Title] 18F-FET PET differentiation of ring-enhancing brain lesions.
  • In all patients, the main differential diagnosis after MRI was a malignant lesion, in particular glioblastoma multiforme, versus a benign lesion, in particular brain abscess.
  • A malignant tumor was suspected for lesions showing increased (18)F-FET uptake on PET images with a mean lesion-to-brain ratio of at least 1.6 ((18)F-FET PET positive).
  • A nonneoplastic lesion was suspected in cases of minimal or absent (18)F-FET uptake, with a mean lesion-to-brain ratio of less than 1.6 ((18)F-FET PET negative).
  • The findings of (18)F-FET PET were positive in all 5 glioma patients and in 3 of 9 patients with nonneoplastic lesions, including 2 patients with brain abscesses and 1 patient with a demyelinating lesion.
  • CONCLUSION: Although (18)F-FET PET has been shown to be valuable for the diagnostic evaluation of brain tumors, our data indicate that, like (18)F-FDG PET, (18)F-FET PET has limited specificity in distinguishing between neoplastic and nonneoplastic ring-enhancing intracerebral lesions.

  • [Title] The high incidence of tumor dissemination in myxopapillary ependymoma in pediatric patients. Report of five cases and review of the literature.
  • Myxopapillary ependymomas (MPEs) have historically been thought to be benign tumors occurring most frequently in adults.
  • Only 8 to 20% of these tumors occur in the first two decades of life, making this tumor a rarity in pediatric neurosurgery.
  • Four (80%) of these five patients suffered from disseminated disease of the central nervous system (CNS) at the time of presentation; this incidence is much higher than that reported in the combined adult and pediatric literature.
  • In those cases in which patients underwent screening for CNS tumor dissemination, however, the incidence of disseminated disease was 58% (seven of 12 patients).
  • In pediatric patients MPEs may spread throughout the CNS via cerebrospinal fluid pathways; therefore, MR imaging of the entire CNS axis is recommended at both presentation and follow-up review to detect tumor dissemination.

  • The progression free survival after SRS (including tumor growth and cyst enlargement) for the entire series was 83.9%, 31.5% and 31.5% at 1, 3 and 5 years, respectively.
  • Despite their purported benign nature, pilocytic astrocytomas in adult patients often do not behave benignly.
  • Unresectable pilocytic astrocytomas that are located in critical or deep areas of the brain require additional management approaches.

  • Myopericytoma is an uncommon, benign perivascular myoid cell tumor that occurs almost exclusively in somatic soft tissues.
  • One patient presented with a bronchial mass and the other developed mass lesions of the tongue, vocal cord, and brain.
  • Histologically, oval to plump spindly tumor cells with uniform nuclei and scanty cytoplasm formed sheets or cuffs around gaping or narrow vascular spaces.
  • The tumor cells were immunoreactive for actin but not desmin, and showed uniform labeling for Epstein-Barr virus (EBV) encoded RNAs on in-situ hybridization.
  • This tumor type therefore also broadens the spectrum of neoplasms associated with EBV.

  • The purpose of this study was to compare the diagnostic value of positron emission tomography (PET) using [(18)F]-fluorodeoxyglucose ((18)F-FDG) and O-(2-[(18)F]fluoroethyl)-l-tyrosine ((18)F-FET) in patients with brain lesions suspicious of cerebral gliomas.
  • RESULTS: Histology revealed 24 low-grade gliomas (LGG) of World Health Organization (WHO) Grade II and 19 high-grade gliomas (HGG) of WHO Grade III or IV, as well as nine others, mainly benign histologies.
  • The gliomas showed increased (18)F-FET uptake (>normal brain) in 86% and increased (18)F-FDG uptake (>white matter) in 35%. (18)F-FET PET provided diagnostically useful delineation of tumor extent while this was impractical with (18)F-FDG due to high tracer uptake in the gray matter.
  • A local maximum in the tumor area for biopsy guidance could be identified with (18)F-FET in 76% and with (18)F-FDG in 28%.
  • In some benign lesions like abscesses, increased uptake was observed for both tracers indicating a limited specificity of both techniques.
  • The uptake of (18)F-FDG is associated with prognosis, but the predictive value is limited and a histological evaluation of tumor tissue remains necessary.

  • [Title] Spinal glioneuronal tumor with neuropil-like islands and meningeal dissemination: histopathological and radiological study of a pediatric case.
  • A distinctive rare form of glioneuronal tumors with neuropil-like islands (GTNI) have been reported to occur in the adult cerebrum, whereas spinal GTNI localization is extremely rare.
  • Histologically the tumor was composed of round, small neurocytic-like cells arranged around eosinophilic neuropil cores and embedded in a diffuse fibrillar glial component forming prominent "rosetted" neuropil islands displaying strong immunoreactivity for neuronal markers.
  • Nevertheless, due to their exceptional rarity, the natural history of these lesions is not yet fully understood, but spinal GTNI seems to have an unfavorable clinical course despite their benign histopathological features, which must be taken into account for appropriate treatment and follow-up of the patient.

  • PURPOSE: Several studies have explored the usefulness of dual time point F-18 FDG positron emission tomography imaging (DTPI) in improving detection of brain metastases and tumors outside the brain, distinguishing malignant from benign.
  • In the same manner, DTPI may show better performance to grade of brain tumors.
  • METHODS: Twenty-two lesions of 18 consecutive patients with primary or metastatic brain tumor were included prospectively.
  • CONCLUSION: DTPI may be a better imaging method to grade the brain tumor than early imaging only.

  • [Title] Correlation of MIB-1 staining index and (201)Tl-SPECT retention index in preoperative evaluation of malignancy of brain tumors.
  • MIB-1 staining provides a useful index of the malignancy of brain tumors.
  • However, because of the difficulty of evaluating malignancy based on the preoperative imaging findings, we investigated the correlation between the (201)Tl-SPECT retention index (RI) and MIB-1 staining index (MIB-1 SI) to determine the usefulness of RI for preoperative evaluation of the malignancy of brain tumors.
  • The subjects of this study were 47 patients who underwent tumor removal surgery at our hospital in 2006 and 2007.
  • The tumors consisted of 16 intraaxial tumors (all gliomas: 9 glioblastomas, 2 anaplastic astrocytomas, 2 anaplastic oligoastrocytomas, 1 oligodendroglioma, and 2 ependymomas), 8 other malignant brain tumors, and 23 extraaxial tumors (10 meningiomas, 7 pituitary adenomas, and 6 schwannomas).
  • RI values may also be useful for evaluating apparently benign extraaxial tumors for possible malignancy.

  • [Title] Clinicopathologic features of recurrent dysembryoplastic neuroepithelial tumor and rare malignant transformation: a report of 5 cases and review of the literature.
  • Dysembryoplastic neuroepithelial tumors (DNETs) have traditionally been viewed as benign "quasihamartomatous" tumors widely considered curable with surgery alone.
  • Although the radiology was often alarming (e.g., new ring enhancing mass), the pathology remained benign in most cases.
  • These findings suggest that these patients may need closer follow-up than initially suggested, lending further support to the notion that this tumor behaves more like a benign neoplasm, rather than a dysplastic or hamartomatous lesion.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Apparent diffusion coefficients for evaluation of the response of brain tumors treated by Gamma Knife surgery.
  • The authors hypothesized that loss of tumor cells after Gamma Knife surgery (GKS) may alter the ADC value and used diffusion weighted MR imaging (DW imaging) to evaluate cellular changes in brain tumors to detect their treatment response and the efficacy of GKS.
  • METHODS: In this paper the authors describe a prospective trial involving 86 patients harboring 38 solid or predominantly solid brain metastases, 30 meningiomas, and 24 acoustic neuromas that were treated by GKS.
  • Follow-up MR images and clinical outcomes were reviewed at 3-month intervals for metastatic lesions and at 6-month intervals for benign tumors.
  • Calcification (p = 0.006) and tumor recurrence (p = 0.025) significantly prevented a rise in the ADC level.The mean ADC value for all solid acoustic neuromas was 1.06 ± 0.17 × 10-3 mm2/sec before GKS.
  • At the last mean MR imaging follow-up there appeared to be tumor enlargement in 3 patients (12.5%); however, since the ADC values in these patients were significantly higher than the preradiosurgery values, the finding was considered to be a sign of radiation necrosis rather than tumor recurrence.
  • In some patients in whom imaging findings are equivocal, ADC values may also be used to distinguish radiation-induced necrosis from tumor recurrence.(DOI: 10.3171/2010.7.GKS10864)

  • [Title] [Brain tumors in patients with intractable epilepsy: a clinicopathologic study of 35 cases].
  • OBJECTIVE: To study the clinicopathologic features of brain tumors occurring in patients with medically intractable epilepsy.
  • METHODS: The clinical, radiologic and pathologic features of brain tumors occurring in 35 patients with intractable epilepsy encountered during the period from January, 2005 to April, 2008 in Xuanwu Hospital were retrospectively reviewed.
  • The histologic types of brain tumors included ganglioglioma (13/35, WHO grade I and 6/35, WHO grade II), dysembryoplastic neuroepithelial tumor (3/35, WHO grade I), pleomorphic xanthoastrocytoma (3/35, WHO grade II), diffuse astrocytoma (1/35, WHO grade II), oligoastrocytoma (1/35, WHO grade II), angiocentric glioma (1/35, WHO grade I) and meningioangiomatosis (1/35).
  • The 6 remaining cases showed features seen in between glioneuronal hamartoma and mixed neuronal-glial tumor.
  • CONCLUSIONS: Brain tumors in patients with medically intractable epilepsy are almost always benign and located in the temporal lobe.
  • Most of them represent mixed neuronal-glial tumors and some show transitional features in-between glioneuronal hamartoma and mixed neuronal-glial neoplasm.
  • The similar morphologic pattern and biological behavior of glioneuronal hamartoma and mixed neuronal-glial tumor may suggest a common pathogenetic mechanism.

  • Malignant gliomas are deadly brain tumors characterized by diffuse invasion into the surrounding brain tissue.
  • Here we describe for the first time the expression of BEHAB/brevican in human brain and characterize two novel glioma-specific isoforms, B/b(sia) and B/b(Deltag), which are generated by differential glycosylation and are absent from normal adult brain and other neuropathologies.
  • In addition, its absence from benign gliomas prompts its use as a diagnostic marker to distinguish primary brain tumors of similar histology but different pathologic course.

  • [Title] Factors influencing activities of daily living using FIM-FAM scoring system before starting adjuvant treatment in patients with brain tumors: results from a prospective study.
  • BACKGROUND: Patients with brain tumors have varied degree of functional and psychological impairments because of factors relating to the tumor or to the treatment they receive.
  • MATERIAL AND METHOD: From August 2007 to April 2008, 150 consecutive adult (>18 years) primary brain tumor patients (median age 40 years; male 88, female 62) registered in a general out-patient neuro-oncology clinic were accrued and detailed data were recorded.
  • Seventy percent had malignant tumor (66% high-grade and 34% low-grade; 70% intra-axial).
  • Univariate analysis showed total FIM-FAM scores not significantly different with age (< or =35 years vs. >35 years; P = 0.994), sex (male versus female; P = 0.133), and grade of the tumor (high-grade versus low-grade; P = 0.142) but were significantly higher in patients with a Karnofsky performance score (KPS) of > or =70 as compared with <70 (P = 0.001), neurological performance scale (NPS) of 0 or 1 vs. 2 or 3; P = 0.001), disease type (benign versus malignant; P = 0.001), and site of disease (cerebral versus cerebellar; P = 0.024).
  • A trend for correlation between tumor sites with the corresponding function as assesses on the FIM-FAM score was observed.
  • There is strong correlation with age, type of tumor, and site of disease with different functional and cognitive domain impairment.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • METHODS: Seventy-five samples of cerebrospinal fluid from patients with gliomas, benign brain tumors and mild brain traumas were collected.
  • A total of 50 samples from gliomas and non-brain-tumors were divided into training sets (33 cases including 17 gliomas and 16 non-brain-tumors) and testing sets (17 cases including 5 gliomas and 12 non-brain-tumors).
  • The cerebrospinal proteins bound to H4 chip were detected by SELDI-TOF MS, the profiles of cerebrospinal protein were gained and then analyzed with artificial neural network algorithm (ANN); and the diagnostic model of cerebrospinal protein profiles for differentiating gliomas from non-brain-tumors was established.
  • Forty-seven of cerebrospinal samples of gliomas and benign brain tumors were divided into training sets (31 cases including 13 gliomas and 18 benign brain tumors) and testing sets (16 cases including 9 gliomas and 7 benign brain tumors), the diagnostic model of cerebrospinal protein profiles for differentiating gliomas from benign brain tumors was established based on the same method.
  • RESULT: The diagnostic model of cerebrospinal protein profiles for differentiating gliomas from non-brain-tumors was established and was challenged with the test set randomly, the sensitivity and specificity were 100% and 91.7%, respectively.
  • The cerebrospinal protein profiling model for differentiating gliomas from benign brain tumors was also developed and was challenged with the test set randomly, the sensitivity and specificity were 88.9%, and 100%, respectively.
  • CONCLUSION: The technology of SELDI-TOF MS which combined with analysis tools of bioinformatics is a novel effective method for screening and identifying tumor biomarkers of gliomas and it may provide a new approach for the clinical diagnosis of glioma.

  • BACKGROUND: The objective of this study is to evaluate the sensitivity and specificity of DWI in differentiating brain abscesses from other intracranial cystic lesions.
  • Lesions appearing hyperintense on DWI with the ADC values of lower than 0.9 +/- 0.13 x 10(-3) mm(2)/s (mean +/- SD) were considered as brain abscess, whereas hypointense lesions on DWI with the ADC values 2.2 +/- 0.9 x 10(-3) mm(2)/s were categorized as nonabscess cystic lesions.
  • RESULTS: Ninety-three of 97 brain abscess lesions were hyperintense on DWI, with significantly low (P = .0001) ADC value (0.87 +/- 0.05 x 10(-3) mm(2)/s) (mean +/- SEM), compared with 48 nonabscess lesions (2.89 +/- 0.05 x 10(-3) mm(2)/s).
  • Four of 97 brain abscess lesions in 65 patients were false negative, and 2 of 50 nonabscess lesions in 50 patients were false positive for the diagnosis of brain abscess.
  • The ADC value of the tumor cysts (2.9 +/- 0.05 x 10(-3) mm(2)/s) was significantly lower (P = .02) compared with benign cysts and neurocysticercosis (3.2 +/- 0.05 x 10(-3) mm(2)/s) among nonabscess group.
  • The sensitivity of DWI for the differentiation of brain abscesses from nonabscesses was 96%; specificity, 96%; positive predictive value, 98%; negative predictive value, 92%; and accuracy of the test, 96%.
  • CONCLUSIONS: Diffusion-weighted imaging has high sensitivity and specificity for the differentiation of brain abscess from other nonabscess intracranial cystic lesions.
