  • [Title] The endoscopic supraorbital approach to tumors of the middle cranial base.
  • BACKGROUND: Access to tumors of the middle cranial base has traditionally required wide surgical exposures via open craniotomies.
  • These open techniques often require the use of potentially disfiguring skin incisions and are often associated with a significant degree of brain retraction and potential morbidity.
  • We report our experience with the use of a minimally invasive supraorbital endoscopic approach through the eyebrow for excision of middle cranial base tumors in 2 cases.
  • METHODS: We describe 2 patients with large-sized middle cranial fossa tumors (a medial sphenoid wing meningioma measuring 6 x 4 cm and a recurrent right cavernous sinus meningioma measuring 4 x 3.5 cm) that were entirely removed via a fully endoscopic supraorbital approach using a 1.5-cm keyhole craniotomy.

  • [Title] Two metachronous tumors induced by radiation therapy: case report and review of the literature.
  • Various radiation-induced tumors, including meningioma, glioma, and sarcoma, have been reported; however, metachronous intracranial double tumors induced by radiation therapy are extremely rare.
  • A 1-year-old boy had undergone tumor removal and craniospinal radiation therapy (30 Gy) for cerebellar medulloblastoma.
  • Six years later, an infiltrative tumor was newly found in the right fronto-temporal white matter.
  • The patient underwent stereotactic biopsy, and the tumor was found to be an anaplastic astrocytoma.
  • Since both secondary tumors were located within the area of previous radiation and the patient did not have any genetic disease predisposing him to tumors, radiation therapy was considered to be responsible for their tumorigenesis.
  • To our knowledge, this case is the fourth case of radiation-induced double CNS tumors arising after radiotherapy to be described in the literature.

  • Myxomas are rare benign tumors arising from mesenchymal tissues throughout the body.
  • These tumors are usually seen in the atrium of the heart and the jawbone.
  • The tumor pathology revealed a diagnosis of myxoma with bone and meningeal involvement.
  • Despite the radical surgery, the tumor showed a local recurrence in three years.
  • The differential diagnosis frequently includes chondrosarcomas, chordoma, metastatic tumors of the skull, hemangiopericytoma, meningioma and other neoplasms of the dura and skull base in this location.

  • Meningiomas are extremely common adult brain tumors originating from meningeal coverings of the brain and spinal cord.
  • While most are slowly growing Word Health organization (WHO) grade I tumors, rare variants (clear cell, chordoid, papillary, and rhabdoid), as well as brain invasive (WHO grade II), atypical (WHO grade II), and anaplastic (WHO grade III) meningiomas are considerably more aggressive.
  • In addition to alterations of CDKN2A, p14(ARF), and CDKN2B tumor suppressor genes on 9p21, a contribution of the wingless (wnt) pathway with alterations of the E-cadherin and beta-catenin proteins, as well as alterations of the hedgehog signaling pathway have been implicated in anaplastic meningiomas.

  • SUMMARY OF BACKGROUND DATA: Neurocutaneous melanosis is a rare congenital syndrome consisting of benign or malignant melanocytic tumors of the central nervous system and cutaneous nevi.
  • In general, patients are treated with palliative therapy, such as shunt placement to reduce intracranial pressure or tumor resection to reduce compression of the brain or spine.
  • Magnetic resonance imaging (MRI) of the spine revealed intradural tumor at the T5 level.
  • Computed tomography myelography showed intradural extramedullary tumor.
  • After the pigmented dura was opened, a pigmented tumor was resected.
  • RESULTS: Histologically, the pigmented tumor represented low grade.
  • The pigmented dura and bone comprised melanin-bearing cells without tumor cells.
  • Meningeal melanocytoma with leptomeningeal melanosis in the absence of cutaneous nevi was diagnosed.
  • CONCLUSION: This patient displayed spinal meningeal melanocytoma and leptomeningeal melanosis without cutaneous nevi.

  • PURPOSE: To report a case of intermediate grade meningeal melanocytoma presenting as a recurrent orbital mass.
  • INTRODUCTION: Melanocytomas are rare, primary, pigmented tumors of the central nervous system, usually presenting as well-circumscribed, encapsulated, solid masses in the posterior cranial fossa and at the spinal region, often attached to the underlying dura.
  • Histological analysis of the excision biopsy of the mass showed a highly cellular, locally infiltrating melanocytic neoplasm suggestive of an intermediate grade meningeal melanocytoma.
  • CONCLUSIONS: Recurrent intermediate grade orbital melanocytomas are rarely encountered and have to be distinguished from other topographically similar primary melanotic tumors.

  • We have followed such postoperative cases by short-interval repeated MRI and have performed stereotactic radiosurgery (SRS) for progressive tumors as a salvage therapy.
  • The objective of this report was assessment of the degree of tumor control, the risk of complications, and the presence of variables that predict outcome in patients treated with SRS for high-grade meningiomas.
  • A mean tumor volume was 4.40cc and a mean marginal dose of SRS was 18.0 Gy (12-20 Gy).
  • After a mean follow-up period of 43.4 months (6-84 months), 13 lesions had progression tumor within the SRS field and 6 lesions had out of the SRS field.

  • Cranially irradiated survivors are predisposed to the development of CNS tumors.
  • Our aim was to describe the incidence of secondary brain tumors and to define the significance of treatment-related risk factors and host characteristics in a cohort of childhood leukemia survivors.
  • Our cohort consisted of 60 consecutive cranially irradiated adult survivors of childhood leukemia treated in Oulu University Hospital (Oulu, Finland); MRI of the brain was performed on 49.
  • The sites of the tumors, their histology, and details of the leukemia treatment were determined.
  • Of the 49 patients, 11 (22%) 1-8 years of age at the time of diagnosis developed meningioma later in life, while no other brain tumors were seen.
  • Systematic brain imaging after the treatment is therefore justifiable.

  • Dorsum sellae meningiomas were classified into 2 types based on tumor location, size, and direction of growth.
  • Type I tumors (dorsum sellae-inferior third ventricle type, four cases) were resected by craniotomy via the frontotemporal or orbitozygomatic approach.
  • Type II tumors (dorsum sellae-third ventricle type, 4 cases) were resected by frontal craniotomy via the transcallosal-interforniceal approach.
  • RESULTS: Complete tumor resection was achieved in all the eight patients.
  • In Type I tumor patients, the only postoperative complication was oculomotor nerve palsy.
  • In Type II tumor patients, the postoperative complications included hyperthermia, electrolyte imbalances, endocrinologic disturbances, and hydrocephalus.
  • CONCLUSIONS: Dorsum sellae meningioma surgery is challenging, and resection of Type II tumors is more difficult than Type I tumors.
  • The selection of a suitable microsurgical approach based on tumor type, and the active treatment of postoperative complications are important means of increasing therapeutic efficacy.

  • [Title] [Efficacy of preoperative radiation therapy in hyper-vascular solitary fibrous tumor].
  • The hyper-vascular form of solitary fibrous tumors (SFTs) is rare and there have been few therapeutic evaluations of this entity.
  • Following radiotherapy, both tumor size and feeder vessels were reduced and we could proceed with gross total removal.
  • The tumor was fed by the left posterior cerebral artery, bilateral middle meningeal arteries and the right occipital artery.
  • The first operation employed an occipital transtentorial approach and a highly vascular tumor was found.
  • Tumor resection was limited due to severe bleeding.
  • Histologically, the tumor showed focal hypercellularity with spindle cells and numerous capillaries.
  • Immunohistochemically, the tumor was diffusely positive for CD34 and a diagnosis of SFT, hyper-vascular subtype, was made.
  • Both the tumor size and vascularity decreased dramatically.
  • Radiotherapy appears effective in reducing the hyper-vascular subtype of SFT and would be one possible therapy to deal with these tumors, given their propensity of excessive bleeding during initial surgery.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] INI1 expression is retained in composite rhabdoid tumors, including rhabdoid meningiomas.
  • Rhabdoid cells are encountered in specific entities, such as malignant rhabdoid tumor and atypical teratoid/rhabdoid tumor, as well as in composite rhabdoid tumors derived secondarily from other tumor types.
  • Although rhabdoid tumors are uniformly aggressive, distinction of the entity from the phenotype remains important for its therapeutic implications.
  • The majority of malignant rhabdoid tumors and atypical teratoid/rhabdoid tumors affect infants and young children, harbor chromosome 22q deletions, and inactivate the INI1/hSNF5/BAF47 tumor suppressor gene on 22q11.2.
  • In contrast, most composite rhabdoid tumors are diagnosed in adults, with FISH detectable 22q losses the exception rather than the rule.
  • However, this assay remains limited since 22q dosages are maintained in 20-30% of malignant rhabdoid tumors and atypical teratoid/rhabdoid tumors.
  • Furthermore, chromosome 22 losses are common in some parent tumor types, particularly meningiomas.
  • The recently developed INI1 antibody shows loss of nuclear expression in malignant rhabdoid tumors and atypical teratoid/rhabdoid tumors, though its status in composite rhabdoid tumors is largely unknown.
  • Therefore, we utilized immunohistochemistry and FISH to study INI1 expression and 22q dosages, respectively, in 40 composite rhabdoid tumors, including 16 meningiomas, 15 carcinomas, three melanomas, two sarcomas, two glioblastomas, and 1 neuroblastoma.
  • Approximately 70% of rhabdoid meningiomas had a 22q deletion, but this was rare in other tumor types.
  • Except for one retroperitoneal leiomyosarcoma, nuclear INI1 expression was retained in all composite rhabdoid tumors, including meningiomas with 22q deletion.
  • Therefore, we conclude that INI1 immunohistochemistry is a relatively simple, sensitive, and specific technique for distinguishing malignant rhabdoid tumor and atypical teratoid/rhabdoid tumor from composite rhabdoid tumor.

  • [Title] Stereotactic radiotherapy of intracranial tumors: a comparison of intensity-modulated radiotherapy and dynamic conformal arc.
  • The purpose of this planning study is to examine the relative merits of these techniques in the treatment of intracranial tumors.
  • RESULTS: In the overall comparison of both techniques, we found adequate target coverage in all cases; a better mean CI with IMRT in concave tumors (p = 0.027); a better mean HI with DCA in meningiomas, complex tumors, and small (< 92 mL) tumors (p = 0.000, p = 0.005, and p = 0.005, respectively); and a higher EUD in the PTV with DCA in convex tumors (gliomas) and large tumors (p = 0.000 and p = 0.003, respectively).
  • CONCLUSIONS: DCA is our preferred SRT technique for most intracranial tumors.
  • Tumor type, size, or shape do not predict a preference for DCA or IMRT.

  • Meningiomas are neoplasms that arise from the leptomeningeal covering of the brain and spinal cord, accounting for 15%-20% of CNS tumors.
  • 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.
  • 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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE AND IMPORTANCE: This is the second report of a Citrobacter-associated brain abscess in an adult and the first report of its association with an intradural tumor.
  • Excluding those associated with trauma, neurosurgical procedures, and proximity to the skull base, only seven other cases of abscesses associated with intracranial tumors have been published.
  • Five of seven tumor-associated abscesses with a microbiological diagnosis involved gram-negative bacteria, a finding that may indicate a predilection of these microorganisms for intracranial tumors.
  • Computed tomographic imaging revealed a noncalcified, homogeneously enhancing, 3-cm-diameter, extra-axial tumor associated with the right anterior falx cerebri.
  • The tumor did not extend to the skull base.
  • INTERVENTION: At craniotomy, 10 to 20 ml of thick pus was found around the posteroinferior surface of the tumor.
  • CONCLUSION: The characteristic endothelial invasiveness of Citrobacter and related gram-negative bacteria may predispose to the formation of abscesses in association with intracranial tumors.

  • [Title] Papillary tumor of pineal region presenting with leptomeningeal seeding.
  • Papillary tumor of the pineal region (PTPR) is a recently recognized and rare pineal tumor, presenting as a solitary mass with or without hydrocephalus.
  • The specimen was small in quantity but nonetheless, revealed the typical features of PTPR, which were tumor cells with vacuolated cytoplasm forming a pseudopapillary architecture.
  • The tumor cells were diffusely immunoreactive for vimentin, INI-1 and c-Kit, focally immunoreactive for neuronal specific enolase (NSE) and S100 protein but negative for cytokeratin, epithelial membrane antigen (EMA), synaptophysin and GFAP.
  • Ultrastructurally, the tumor cells revealed variably-sized cytoplasmic vacuoles, intermediate filaments and villous cytoplasmic membrane.
  • This case was a c-kit expressing PTPR, which might represent the more primitive nature of this tumor.
  • Ultrastructural examination is useful to differentiate PTPR from other tumors of the pineal gland in addition to immunohistochemistry.

  • To minimize the risk of functional deficits, larger tumors were treated with the combination of intentional partial resection followed by GKRS.
  • Residual or recurrent tumors in patients who had undergone extirpations prior to GKRS (19 CSMs, 6 PFMs) are not eligible for this treatment method (due to the surgeries not being performed as part of a combination strategy designed to preserve neurological function as the first priority).
  • The overall tumor control rates were 95.5% in CSMs and 98.4% in PFMs.
  • Nearly all tumors treated with GKRS alone were well controlled and the patients had no deficits.
  • CONCLUSION: Our results indicate that GKRS is a safe and effective primary treatment for SBMs with small to moderate tumor volumes.
  • We also found that larger SBMs compressing the optic pathway or brain stem can be effectively treated, minimizing any possible functional damage, by a combination of partial resection with subsequent GKRS.

  • Intracranial hemangiopericytomas are a rare type of primary brain tumor, representing only about 0.5% of all primary brain tumors.

  • In addition, in a subgroup of 45 (12 male and 33 female) patients, tumors were hybridized with the Affymetrix U133A chip.
  • We show a higher frequency of larger tumors (p = .01) and intracranial meningiomas (p = .04) together with a higher relapse rate (p = .03) in male than in female patients.
  • Male patients had a higher percentage of del(1p36) (p < .001), while loss of an X chromosome was restricted to tumors from female patients (p = .008).
  • In turn, iFISH studies showed a higher frequency of chromosome losses, other than monosomy 22 alone, in meningiomas from male patients (p = .002), while female patients displayed a higher frequency of chromosome gains (p = .04) or monosomy 22 alone (p = .03) in the ancestral tumor clone.
  • In turn, gene expression showed that eight genes (RPS4Y1, DDX3Y, JARID1D, DDX3X, EIF1AY, XIST, USP9Y, and CYorf15B) had significantly different expression patterns (R(2) > 0.80; p < .05) in tumors from male and female patients.

  • Seventy-seven per cent of tumors (34 cases) were operated on; 6 tumors (14.6%) were exclusively irradiated using fractionated radiation therapy (FRT) and four only surveyed (9,8%).
  • Surgical removal was incomplete in 11,8% of cases; in 3 cases growing tumor was treated by FRT included one case of anaplasic tumor Postoperative complications were: 1 meningitis, 1 wound abscess, 2 hydrocephalus (6%) and 4 CSF fistulas (12%).
  • Radiation therapy allowed tumor shrinkage in all cases.
  • Transpetrosal approaches and particularly WRLA pure or combined to a transtentorial approach are for us the best way to remove these tumors in preserving hearing and facial nerve function.
  • When hearing is poor or when tumor extension to the clivus or the premeatal area is consistent a TLA is either planned preoperatively or obtained from a WRLA.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECT: The authors analyzed tumor control rates and complications in patients with superficially located meningiomas after gamma knife surgery (GKS).
  • The median tumor volume was 4.7 cm3, and the mean margin dose was 16 Gy at the 50% isodose line.
  • The tumor shrank in eight cases, was stable in 17, and enlarged in one; thus 25 (95%) of 26 tumors were controlled.
  • High signal was associated with a high integral dose and a large tumor volume.
  • Tumor shrinkage at the last follow-up examination was more prominent in the patients with symptomatic high signal (p = 0.03).
  • CONCLUSIONS: There was a good tumor control rate with a high complication rate.

  • [Title] Absence of histological signs of tumor progression in recurrences of completely resected meningiomas.
  • In meningioma recurrences a tumor progression has been proposed on a molecular genetic basis.
  • Recurrences mainly depend on tumor location, histology, resection type and on the tumor growth in the adjacent nervous tissue.
  • Most tumors were convexity or parasagittal meningiomas.
  • The number of recurrences studied per tumor varied from 1 to 5.
  • Loss of heterozygosity (LOH) of CDKN2A was found to be slightly more frequent in the first recurrence than in the initial tumor, but it was lower in the following recurrences.
  • The nervous tissue adjacent to the tumor could contain meningothelial cells and be responsible for recurrences.
  • The number of mitoses appeared to be the most important criterion for establishing the tumor grade.
  • The greater number of recurrences in atypical and anaplastic tumors depends on their initial higher proliferation capacity.
  • The occurrence of tumor meningothelial cells in the adjacent nervous tissue or in the thickened arachnoidal membrane can be responsible for recurrence.

  • Hemangiopericytomas (HPC) of the central nervous system (CNS) are uncommon dural-based tumors that mimic meningiomas clinically and radiologically.
  • Because there are few reports about these tumors from India, we aimed to study the clinico-pathological and immunohistochemical features of CNS HPC.
  • There were 14 patients with grade II and nine with grade III tumors.
  • Immunohistochemistry with antibodies to epithelial membrane antigen (EMA), vimentin, S-100, CD34 and Ki-67 was done on routinely processed, paraffin-embedded sections of 20 tumors.
  • The mean Ki-67 labeling index was 4.25% in grade II tumors and 7.8% in grade III tumors.

  • [Title] [Microsurgical treatment of posterior cranial fossa tumors via keyhole approaches].
  • OBJECTIVE: To explore the surgical outcome and skills of keyhole approaches to posterior cranial fossa tumors.
  • METHODS: A retrospective analysis of the clinical data of 43 consecutive patients with posterior cranial fossa tumors, including acoustic neurinoma, petroclival meningioma, pons tumor, fourth ventricular tumor, etc. was conducted.
  • Subtemporal, retromastoid, or middle suboccipital keyhole approach was chosen respectively according to the anatomic positions of those different tumors.
  • RESULTS: The tumors were totally removed in 37 of the 43 patients (86.0%), subtotally removed in 5 (11.6%) and mostly removed in 1 (2.3%).
  • All of the 18 acoustic neurinomas (100%) were totally removed and the facial nerves of 15 patients (83.3%) were preserved anatomically, however, one patient died of brain stem edema on the 2nd postoperative day.
  • Among the 6 pons tumors 3 were removed totally and 3 subtotally.
  • All the other tumors were resected completely without neurological dysfunction observed, however, one patient with a cholesteatoma failed to demonstrate apparent improvement in his diplopia.
  • CONCLUSION: Microsurgical treatment of posterior cranial fossa tumors via keyhole approaches, with safe, succinct and minimally invasive property, is one of the promising directions in modern neurosurgery.

  • Of 411 patients with intracranial meningioma treated with radiotherapy at our institution, 22 patients with local tumor progression diagnosed by magnetic resonance imaging (MRI) after radiotherapy (RT) were identified and further investigated.
  • Median time to local tumor progression and site of local recurrence significantly depended on histological grade of meningioma.
  • Regarding site of failure, improvement of dose coverage for benign meningiomas and dose escalation for high-grade tumors might further improve therapy outcome.

  • [Title] Gamma Knife surgery for trigeminal pain caused by benign brain tumors.
  • 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.
  • These patients harbored tumors within the radiosurgical target area.
  • 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.

  • OBJECTIVE: Standard approaches to thoracic intradural tumors often involve a large incision and significant tissue destruction.
  • Minimally invasive techniques have been applied successfully for a variety of surgical decompression procedures but have rarely been used for the removal of intradural thoracic tumors.
  • Here, we demonstrate the feasibility and initial clinical experience with a new minimally invasive approach for resection of intradural tumors.
  • Subsequently, the transspinous mini-open approach was used to biopsy one clinical case of intradural, intramedullary tumor (glioblastoma multiforme) and to remove two intradural, extramedullary tumors (meningiomas) in two other patients.
  • The mini-open transspinous resection of thoracic intradural tumors can be performed safely.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: From a surgical perspective, tentorial fold (TF) meningiomas (TFM) are a unique entity of tumors.
  • We present our experience with this rare tumor entity and demonstrate the surgical outcome related to a topographical classification.
  • The cases were classified according to tumor extension in three different types: type I, TF meningiomas with compression of the brain stem; type II, with extension into the anterior portion of middle fossa; and type III, a combination of type I and II.
  • Depending on tumor location, surgical approaches consisted of pterional (nine cases), subtemporal (nine cases), or combined subtemporal-pterional craniotomies (three cases).
  • RESULTS: Tumor size ranged from 1 to 6 cm in diameter, with a median at 2.5 cm.
  • Extent of tumor resection was Simpson grade II in 19 patients, grade III in one patient, and grade IV in one patient.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • STUDY DESIGN AND METHODS: Patients undergoing endoscopic skull base surgery underwent an algorithmic approach to reconstruction based on tumor location, defect size, and presence of intraoperative cerebrospinal fluid (CSF) leak.
  • RESULTS: The diagnosis in the 127 patients in this series included pituitary tumor in 70 (55%) patients, encephalocele in 16 (12.6%) patients, meningioma in 11 (8.7%) patients, craniopharyngioma in 9 (7.1%) patients, and chordoma in 6 (4.7%) patients.
  • Correlation between postoperative CSF leak and study variables revealed a statistically significant longer duration of surgery (243 vs. 178 min, P = .008) and hospitalization (12.1 vs. 4.5 days, P < .0001) and a trend toward larger tumors (mean, 3.2 vs. 2.3 cm; P = .058) in patients experiencing postoperative CSF leak.

  • OBJECTIVE: Although tumors are generally expected to grow exponentially, it is not known whether meningiomas retain a constant growth rate or not because of the lack of long-term follow-up.
  • Seven patients (including two neurofibromatosis cases) had incidental tumors.
  • Another 13 patients with symptomatic tumors were followed after surgery.
  • Two calcified tumors did not grow.
  • Although the other benign tumors grew exponentially or linearly, their tumor volume doubling times in the initial phase were shorter than those in the later phase in most cases.
  • This was supported by the observation that in two patients, the tumor growth pattern changed from exponential to linear and from linear to no growth with progression of calcification.

  • As PpIX preferentially accumulates in the tumor tissue in comparison with normal tissue, this red fluorescence becomes a good hallmark for discrimination between normal and tumor tissues, especially in malignant gliomas, which have infiltrative characteristics.
  • Approximately 80% to 90% of the malignant gliomas show this red fluorescence in surgery as mentioned above, while only a limited number of metastatic brain tumor cases do.
  • In the surgery for metastatic brain tumor and lesionectomy for radiation necrosis and neurodegenerative disease, white matter around the lesion showed vague fluorescence, which also provided us with a hallmark in the surgery.
  • Additionally, in meningioma, some tumors showed the red fluorescence, which is especially helpful in the removal of the infiltrative portion in the bone and normal parenchyma.

  • METHODS: Twenty-one MC patients (including 13 adenocarcinoma and 8 non-adenocarcinoma patients), 72 patients with tuberculous meningitis (TBM) and 23 with primary intracerebral tumors (PIT) were enrolled in this study.
  • Blood and CSF tumor markers including CEA, CA125, CA15-3, CA19-9, CA72-4, CYFRA21-1, AFP and NSE were measured by Roche E170 electrochemiluminescence analyzer and sandwich assay.
  • RESULTS: CSF tumor markers CEA, CA125, CA199 and CYFRA21-1 and the serum tumor markers CEA, CA125, CA153, CA199 and AFP were significantly higher in MC group than in the other two groups.
  • CSF CEA and CA15-3 were significantly higher in adenocarcinoma MC than in non-adenocarcinoma MC patients, but no significant differences were found in the serum tumor markers between the two groups (P>0.05).
  • CSF tumor markers including CEA, CA125, CA15-3, CA72-4 and CYFRA21-1 were positively correlated to the serum tumor markers (P<0.05).
  • CONCLUSION: Detection of the tumor markers in the CSF, especially CEA, CA125, CA19-9 and CYFRA21-1, may help in the early diagnosis of MC.

  • OBJECTIVE: Recurrent cranial base meningiomas are among the most difficult tumors to treat surgically.
  • Although they are histologically benign, these tumors often invade through the cranial base into the infratemporal and pterygopalatine fossae.
  • We reviewed our experience with these tumors to describe the natural history of these lesions as well as provide a possible treatment paradigm.
  • The original site of tumor was the sphenoid wing in four patients, the middle fossa in two patients, and the left frontal region in one patient.
  • The average interval between the most recent tumor resection and recurrence into the face was 9.9 years.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECT: Sphenoorbital meningiomas (SOMs) are complex tumors involving the sphenoid wing, orbit, and cavernous sinus, which makes their complete resection difficult or impossible.
  • Sphenoidal hyperostosis that results in incomplete resection makes these tumors prone to high rates of recurrence with postoperative morbidity resulting in a nonfunctional globe.
  • High-dose radiation therapy has often been described as the only treatment capable of achieving tumor control, although often at the expense of the patient's progressive visual deterioration.
  • There was tumor recurrence in 8% of patients; in one case recurrence was delayed for longer than 11 years.
  • CONCLUSIONS: Sphenoorbital meningiomas are a distinct category of tumors complicated by potentially extensive hyperostosis of the skull base.

  • [Title] Craniofacial resection for sinunasal tumors.
  • INTRODUCTION: Malignant sinonasal tumors are very rare in Mexico.
  • OBJECTIVE: We undertook a retrospective analysis in order to evaluate results of craniofacial resections for sinonasal tumors.
  • In 13 patients tumor was limited to maxillo-ethmoid complex, but in 6 cases tumor involved anteroinferior aspect of sphenoid sinus, in 7 extended to the orbit, in 3 to dura and two to the brain.
  • CONCLUSIONS: Craniofacial resection is a safe and valuable tool in the treatment of advanced sinonasal tumors involving cranial base.

  • [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.
  • Three presented cases fulfilled these diagnostic criteria; however, it seems that progression of the tumors (schwannoma, meningioma, chordoma) resulted from the natural course of the disease, rather than represented side effects of gamma knife radiosurgery.
  • 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.

  • The T1-weighted MRI images showed a tumor hyperintensity, the T2-weighted images showed tumor isointensity and mild contrast enhancement.
  • The tumor was composed of irregular melanocytoid cells with high proliferation index (20%).
  • Radiotherapy was performed on the site of the tumor.
  • The most common tumor with root enlargement and bony scalloping is the benign schwannoma.
  • Despite the above described radiological features, MRI characteristics (hyperintensity when images are T1-weighted) suggest a melanocytic tumor, a tumor with a high adipose component or an intratumoral bleeding.
  • Specific MRI sequences can eliminate adipose tissue tumor, but diagnosis between melanin and methemoglobin is still difficult.
  • According to the index of proliferation, a primitive central melanocytic lesion can be a meningeal melanocytoma (considered as benign) or a primitive malignant melanoma.
  • These tumors show identical protein expressions in immunohistochemistry, and their prognosis is very variable (some long-term remissions are reported for malignant melanomas and fast disseminations are described for meningeal melanocytomas treated by sub-total surgery).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECT: The authors retrospectively analyzed a consecutive series of patients with cranial vault primary extradural meningioma (PEM), with particular regard to the tumor's dural involvement.
  • The authors created a classification system based on dural involvement of the tumors.
  • Preoperative magnetic resonance (MR) imaging revealed dural enhancement at the site of tumor in 11 patients.
  • On surgical inspection, the tumor infiltrated the dura in all but three patients.
  • Histological examination of tissue samples demonstrated tumor infiltration of the dura in all 14 patients in whom the dura had been resected.
  • Three recurrent tumors were observed on follow-up examination during a mean period of 5.8 years (range 1.5-13 years) and required extirpation.
  • CONCLUSIONS: Tumor infiltration of the dura should be assumed in PEMs of the cranial vault, and resection of the dura at the site of craniotomy is recommended to prevent tumor recurrence.

  • [Title] Comparison between neuroimaging classifications and histopathological diagnoses using an international multicenter brain tumor magnetic resonance imaging database.
  • OBJECT: The aim of this study was to estimate the accuracy of routine magnetic resonance (MR) imaging studies in the classification of brain tumors in terms of both cell type and grade of malignancy.
  • METHODS: The authors retrospectively assessed the correlation between neuroimaging classifications and histopathological diagnoses by using multicenter database records from 393 patients with brain tumors.
  • Each tumor category was compared with the corresponding histopathological diagnoses by dichotomization.
  • In routine reporting of MR imaging examinations, tumor types and grades were classified with a high specificity (85.2-100%); sensitivity varied, depending on the tumor type and grade, alone or in combination.
  • The recognition of broad diagnostic categories (neuroepithelial or meningeal lesions) was highly sensitive, whereas when both detailed type and grade were considered, sensitivity diverged, being highest in low-grade meningioma (sensitivity 100%, 95% CI 96.2-100.0%) and lowest in high-grade meningioma (sensitivity 0.0%, 95% CI 0.0-65.8%) and low-grade oligodendroglioma (sensitivity 15%, 95% CI 5.2-36.0%).
  • In neuroepithelial tumors, sensitivity was inversely related to the precision in reporting of grade and cellular origin; "glioma" was a frequent neuroimaging classification associated with higher sensitivity in the corresponding category.
  • This study targets the need for noninvasively increasing sensitivity in categorizing most brain tumor types while retaining high specificity, especially in the differentiation of high- and low-grade glial tumor classes.

  • [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).

  • Approximately 60% of sporadic meningiomas are caused by inactivation of the NF2 tumor suppressor gene on chromosome 22.
  • Cytogenetic analysis shows that meningiomas caused by inactivation of the NF2 gene can be divided into tumors that show monosomy 22 as the sole abnormality and tumors with a more complex karyotype.
  • Unexpectedly and regardless of genotype, a subgroup of tumors was observed with an average number of 44.9 chromosomes and little variation in the number of chromosomes per metaphase spread.
  • In cultured cells of all tumor groups, bi- and multinucleated cells were seen, as well as anaphase bridges, residual chromatid strings, multiple spindle poles, and unseparated chromatids, suggesting defects in the mitotic apparatus or kinetochore.
  • Thus, we conclude that even a benign and slow-growing tumor like a meningioma displays chromosomal instability.

  • PURPOSE: Recurrence is the major factor influencing the clinical outcome of meningioma patients although the exact relationship between primary and recurrent tumors still needs to be clarified.
  • EXPERIMENTAL DESIGN: Multicolor interphase fluorescence in situ hybridization was done for the identification of numerical abnormalities of 12 chromosomes in single-cell suspensions from 59 tumor samples corresponding to 25 recurrent meningioma patients.
  • In 47 of these tumors, the distribution of different tumor cell clones was also analyzed in paraffin-embedded tissue sections.
  • RESULTS: Most recurrent meningiomas showed complex cytogenetic aberrations associated with two or more tumor cell clones in the first tumor analyzed.
  • Interestingly, in most individuals (74%), exactly the same tumor cell clones identified in the initial lesion were also detected in the subsequent recurrent tumor samples.
  • In the recurrent tumor samples of the remaining cases (26%), we observed tumor cell clones related to those detected in the initial lesion but which had acquired one or more additional chromosome aberrations associated with either the emergence of new clones with more complex karyotypes or the disappearance of the most representative clones from the primary lesions.
  • Multivariate analysis of prognostic factors showed that the Maillo et al. prognostic score, based on age of patient, tumor grade, and monosomy 14, together with tumor size was the best combination of independent variables for predicting tumor recurrence at diagnosis.
  • CONCLUSION: Overall, our results indicate that the development of recurrent meningiomas after complete tumor resection is usually due to regrowth of the primary tumor and rarely to the emergence of an unrelated meningioma, underlining the need for alternative treatment strategies in cases at high risk of relapse, particularly those with a high Maillo et al. prognostic score and larger tumors.

  • Following previous determination of their activities in monkey brains, their activities were evaluated in human brain tumors.
  • Both enzyme activities were measured in the 55 most frequent human brain tumors (glioblastomas, pituitary adenomas, meningiomas, astrocytomas).
  • Significant differences were found in STS activity among investigated types of tumors except the pair of pituitary adenomas-glioblastomas, while significant differences were found in SULT activity among investigated types of tumors.

  • [Title] Expression of vascular endothelial growth factor in human meningiomas and peritumoral brain areas.
  • Recent reports suggest that VEGF may play a critical role in formation of peritumoral brain edema (PTBE) associated with meningiomas.
  • While VEGF expression has been shown in meningiomas, studies have not focused on VEGF in the adjacent peritumoral brain regions.
  • The present study examined the protein and gene expression of VEGF in human meningiomas and peritumoral brain areas.
  • In VEGF-positive cases, a decreasing gradient of VEGF protein expression was observed with increasing distance from tumors.
  • We conclude that VEGF macromolecules are secreted by the tumor tissue and enter peritumoral normal brain tissue to induce edema.

  • [Title] Surgical considerations in the management of falcotentorial meningiomas: advantages of the bilateral occipital transtentorial/transfalcine craniotomy for large tumors.
  • OBJECTIVE: Meningiomas arising from the falcotentorial junction are relatively rare, and the description of the surgical nuances in approaching these tumors is limited.
  • The angiograms revealed that these tumors were fed by branches of the internal carotid artery, choroidal arteries, branches of the meningohypophyseal trunk, and branches of the posterior cerebral artery.
  • Two of the tumors (22%) recurred during a mean follow-up period of 49 months (range, 17-88 months).

  • METHODS: The medical records of 160 patients with 184 tumors were examined for those with follow-up data of more than 2 years among 270 patients who underwent GKS for intracranial meningiomas between February 1992 and November 2001.
  • The tumor location was the sphenoid ridge in one case, petroclival in two, tentorium in one, and parasagittal region in one.
  • The mean tumor volume was 10.5 cm3, the mean margin dose was 13.4 Gy (median 14 Gy), and the mean maximum dose was 27.5 Gy (median 24.1 Gy).
  • At the time of GKS three tumors were associated with cyst, of which two enlarged after radiosurgery.
  • Histological examination demonstrated various findings such as tumor necrosis, proliferation of small vessels, vascular obliteration, and hemosiderin deposits.

  • [Title] Tumor extension in high-grade gliomas assessed with diffusion magnetic resonance imaging: values and lesion-to-brain ratios of apparent diffusion coefficient and fractional anisotropy.
  • PURPOSE: To determine whether the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) can distinguish tumor-infiltrated edema in gliomas from pure edema in meningiomas and metastases.
  • ADC and FA were determined from ROIs placed in peritumoral areas with T2-signal changes, adjacent normal appearing white matter (NAWM), and corresponding areas in the contralateral healthy brain.
  • Values and lesion-to-brain ratios from gliomas were compared to those from meningiomas and metastases.
  • RESULTS: Values and lesion-to-brain ratios of ADC and FA in peritumoral areas with T2-signal changes did not differ between gliomas, meningiomas, and metastases (P = 0.40, P = 0.40, P = 0.61, P = 0.34).
  • Values of ADC and FA and the lesion-to-brain ratio of FA in the adjacent NAWM did not differ between tumor types (P = 0.74, P = 0.25, and P = 0.31).
  • The lesion-to-brain ratio of ADC in the adjacent NAWM was higher in gliomas than in meningiomas and metastases (P = 0.004), but overlapped between tumor types.
  • CONCLUSION: Values and lesion-to-brain ratios of ADC and FA in areas with T2-signal changes surrounding intracranial tumors and adjacent NAWM were not helpful for distinguishing pure edema from tumor-infiltrated edema when data from gliomas, meningiomas, and metastases were compared.

  • [Title] Increased frequency of rapid acetylator genotypes in patients with brain astrocytoma and meningioma.
  • We investigated the association between the genetic NAT2 polymorphism and brain tumors by analysis of genomic DNA from 71 brain tumor patients and 258 healthy controls.
  • A higher number of individuals carrying functional NAT2 genes, and therefore with a rapid acetylation phenotype, was found in brain tumor patients vs healthy volunteers (OR 1.79, 95% CI 1.05-3.05; P < 0.05).
  • This is observed either for patients suffering from meningioma or astrocytoma, and this is due to an increase of the wild-type NAT2*4 allelic variant frequency (OR 1.48, 95% CI 0.99-2.19), and a reduction of the commonest defective allelic variant NAT2*5B in the brain tumor patients, compared with healthy subjects (OR 0.54, 95% CI 0.37-0.80).
  • CONCLUSIONS: This observation indicates that NAT2 could be considered as a low-penetrance gene for brain tumors, and that individuals carrying rapid acetylation alleles are at increased risk of developing brain tumors.
