  • [Title] Effect of everolimus on cell viability in nonfunctioning pituitary adenomas.
  • CONTEXT: Pituitary adenomas can cause specific syndromes due to hormone excess and/or determine sellar mass symptoms.
  • Pituitary cell growth can sometimes be influenced by medical therapy, such as for somatotroph adenomas treated with somatostatin analogs or prolactinomas treated with dopaminergic drugs.
  • However, nonfunctioning pituitary adenomas (NFAs) are still orphans of medical therapy.
  • Everolimus (RAD001), a derivative of rapamycin, is a well-known immunosuppressant drug, which has been recently shown to have antineoplastic activity in several human cancers.
  • Cell viability and apoptosis were evaluated after 48 h, and vascular endothelial growth factor (VEGF) secretion was assessed after an 8-h incubation.
  • RESULTS: In 28 cultures (70%), Everolimus significantly reduced cell viability (by approximately 40%; P < 0.05 vs. control), promoted apoptosis (+30%; P < 0.05 vs. control), inhibited p70S6K activity (-20%), and blocked IGF-I proliferative and antiapoptotic effects.
  • In selected tissues cotreatment with SOM230, but not cabergoline, exerted an additive effect.
  • CONCLUSIONS: Everolimus reduced NFA cell viability by inducing apoptosis, with a mechanism likely involving IGF-I signaling but not VEGF secretion, suggesting that it might represent a possible medical treatment of invasive/recurrent NFAs.

  • The patient underwent transsphenoidal debulking, and the tissue obtained demonstrated immunohistochemical staining for LH.
  • A literature review revealed nine previously reported cases of pituitary apoplexy after GnRH agonist therapy for prostate cancer.
  • In most cases, the sellar tissues stained for LH, consistent with a gonadotropinoma.
  • Particular attention to clinical findings suggestive of a non functioning pituitary tumor in patients receiving GnRH agonist therapy is critical as routine screening with MRI is not practical.

  • [Title] Metastatic pancreatic neuroendocrine tumor presenting as a pituitary space occupying lesion: a case report.
  • Neuroendocrine tumor metastases to the pituitary gland are very rare.
  • There are few case reports of carcinoid tumor metastases to the pituitary, but no cases of pancreatic neuroendocrine pituitary metastases have been reported.
  • In this report we present a 55-year-old female with a sellar mass, ophthalmoplegia and headaches initially thought to represent an invasive null cell pituitary adenoma.
  • However a histological (trans-sphenoidal and liver biopsies) and systemic investigation proved it to be a metastasis of an undiagnosed pancreatic neuroendocrine tumor.
  • Our patient was unique in respect to the location of the metastasis and the uncharacteristically high proliferative index of her tumor.
  • She received conventional therapy consisting of Sandostatin, chemotherapy and radiotherapy as well as labeled somatostatin following an avid uptake on octreotide scanning.

  • However, no such malignant tumour has been described in the sellar region.
  • Upon initial admission, no endocrinological abnormalities were found, and computed tomography and magnetic resonance imaging revealed a mass with calcification in the sella and right cavernous sinus.
  • INTERVENTION: For this malignant tumour, three surgical resections, two sessions of gamma-knife radiosurgery, one session of fractional irradiation, and one cycle of chemotherapy were performed, resulting in only brief arrest of the tumour growth.
  • Pathologically, the tumour consisted of undifferentiated small cells of high cellularity, and islands of hyaline cartilage.
  • CONCLUSION: Although malignant tumours in the sellar region are rare, they should be considered in the differential diagnosis of various sellar tumours typified by non-functioning pituitary adenoma, and mesenchymal chondrosarcoma is one possible candidate.

  • We report a first case of a 30 year-old woman affected by polycystic ovarian disease (PCOD) whose amenorrhea ceased after a 6-month combination treatment with cyclic estradiol-norethisterone acetate.
  • After the withdrawal of the hormone therapy, a stable recovery of periodic menses was observed.
  • We describe a second case of a 23 year-old woman whose amenorrhea was caused by a hypogonadotropic hypogonadism due to a non-functioning pituitary adenoma.
  • After the administration of the previously described therapy both a disappearance of the adenoma and a recover of periodic menses were observed.
  • The exogenous hormones may have reset the feedback between the hypothalamus and pituitary gland through mimicking the physiological hormones pattern of the 28-day cycle.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The prolactin regulatory element-binding protein (PREB) is a transcriptional factor that regulates prolactin (PRL) promoter activity in the anterior pituitary.
  • Prolactinomas are the most common pituitary tumors.
  • Administration of cabergoline, a selective dopamine D2-receptor agonist, has become the initial therapy of choice for most patients with prolactinomas.
  • Samples of ten prolactinomas and ten nonfunctioning pituitary adenomas were analyzed by immunohistochemistry to detect the expression of PREB.
  • The effect of cabergoline on PREB expression was assessed by western blotting and real-time polymerase chain reaction (PCR) analysis.
  • Immunohistochemical analysis revealed strong positive PREB expression in the prolactinoma tissue, but extremely weak or undetected expression in the nonfunctioning pituitary tumor tissue.
  • Western blots probed with a PREB-specific antiserum revealed that the relative abundance of the PREB protein in the GH3 cells decreased in a dose-dependent manner in response to cabergoline treatment, as did the relative abundance of PREB mRNA.

  • [Title] [Macroadenoma of the pituitary gland with moderate hyperprolactinaemia].
  • [Transliterated title] Makroadenom der Hypophyse mit mässiger Hyperprolaktinämie.
  • HISTORY AND CLINICAL FINDINGS: A 46-year-old woman was referred to the neurosurgery department for treatment of a macroadenoma of the pituitary.
  • INVESTIGATIONS: The endocrinological work-up revealed a moderately elevated prolactin level of 3133 mU/l (147 ng/ml) with intact pituitary functions.
  • She had no visual impairment and the MRI depicted a pituitary tumor with a maximal diameter of 1.9 cm and both intra- and suprasellar extension.
  • DIAGNOSIS, TREATMENT AND CLINICAL COURSE: The diagnosis of a nonfunctioning macrodenoma with functional hyperprolactinemia was made and a selective transsphenoidal adenomectomy was performed.
  • The primary histology showed a chromophobe adenoma.
  • In the meantime, because of persistent galactorrhea and elevated prolactin levels, treatment with cabergolin 0.5 mg/week was started.
  • A follow-up MRI after 3 months of treatment showed a significant shrinkage of the residual tumor.
  • CONCLUSION: This case demonstrates that the differential diagnosis of macroprolactinoma with low secretory activity and functional hyperprolactinemia is very difficult preoperatively in individual cases.
  • This is relevant because macroprolactinomas with low secretory activity can also be treated successfully with dopamine agonists.
  • We therefore suggest a drug treatment trial with dopamine agonists in all macroadenoms with hyperprolactinemia, particularly in those with prolactin levels above 2000 mU/l (100 ng/ml).

  • All 84 TBI patients were matched with 84 patients with GHD due to non-functioning pituitary adenoma (NFPA) also included in this database.
  • Analysis of clinical and outcome variables was performed, with comparisons of childhood vs. adult TBI, and TBI vs. NFPA patients, at baseline and one-year follow-up.
  • RESULTS: TBI patients with GHD were significantly younger at the onset of pituitary disease and exhibited a significantly longer time span between GHD diagnosis and KIMS entry than NFPA patients.
  • At 1-year follow-up, insulin-like growth factor I (IGF-I) standard deviation score levels had returned to the normal range and quality of life (QoL), as measured by QoL- Assessment of Growth Hormone Deficiency in Adults (AGHDA) questionnaire, improved significantly in TBI as in NFPA patients.
  • CONCLUSION: This analysis provides preliminary data that TBI patients with GHD benefit from hGH replacement in terms of improved QoL in a similar fashion as do NFPA patients.
  • Moreover, it suggests that belated diagnosis and treatment in childhood-onset GHD due to TBI might be related to a shorter final height in these children.

  • [Title] Growth hormone (GH) replacement therapy in GH deficient adults: predictors of one-year metabolic and clinical response.
  • OBJECTIVE: This study investigated whether baseline status could predict the responsiveness to one-year growth hormone (GH) replacement therapy in adult GH deficient (GHD) patients.
  • DESIGN: A total of 380 European patients with adult onset GHD due to non-functioning pituitary adenoma that had been enrolled in Pfizer International Metabolic Database (KIMS), and that had completed one year of GH replacement therapy within KIMS, were studied.
  • Quality of life (QoL)-Assessment of GHD in Adults (QoL-AGHDA), waist circumference, waist:hip ratio, and serum lipid pattern improved.
  • Women received a higher dose of GH than men after one year, and demonstrated similar treatment response.
  • In multiple stepwise forward regression analyses, the one-year changes in QoL-AGHDA score, waist:hip ratio, and serum low density lipoprotein-cholesterol (LDL-C) level correlated inversely with the baseline values of the same variable.
  • In addition, the change after one year in QoL-AGHDA score correlated inversely with duration of hypopituitarism and baseline serum high density lipoprotein-cholesterol (HDL-C) level, and the change in waist:hip ratio correlated inversely, although more weakly, with baseline serum HDL-C level and UK citizenship and positively with baseline waist circumference and the initial GH dose.
  • Therefore, when the decision to start GH replacement is undertaken, as many outcome variables as possible should be evaluated in order to adequately evaluate the likelihood of clinical benefit.
  • Finally, women have a similar response to GH replacement as men when individualised GH dosing schedules are employed and should therefore be selected for GH therapy to a similar extent.

  • [Title] Pituitary tumors in children: clinical analysis of 21 cases.
  • OBJECTIVE: The aim of this study is to review the results of surgery for pituitary adenomas in children less than 18 years old.
  • MATERIALS AND METHODS: A retrospective review was done of pituitary adenoma patients with the age of less than 18 years who were treated in the period 1979-2003 at Dr.
  • Eight patients (38.1%) had adrenocorticotropic hormone-secreting tumors, 33.3% had prolactin-secreting tumors, 19% had growth hormone-secreting tumors, and 9.53% had nonfunctioning adenomas.
  • Multidisciplinary management included surgery and, if necessary, reoperation with/without radiotherapy and pharmacotherapy.
  • Eleven patients, mostly with prolactinomas, acromegaly, and nonfunctioning adenomas, needed reoperation and radiotherapy.
  • The biological behavior of pediatric pituitary adenomas seems more aggressive than adults' adenomas.
  • The chance of pituitary apoplexy in pediatric invasive pituitary adenoma is high.

  • Advances in immunocytochemistry, electron microscopy, cell culture, and molecular techniques have demonstrated that 80 to 90% of the clinically nonfunctioning pituitary adenomas are gonadotrope-derived and recently recognized as gonadotropinomas, which account for as many as 40 to 50% of all pituitary macroadenomas.
  • Commonly, the tumor is found incidentally.
  • The tumors can be divided into two broad categories: functioning gonadotropinomas with positive immunostaining for follicle-stimulating hormone, leutinizing hormone, and/or their subunits; and nonfunctioning gonadotropinomas or null cell tumors with negative immunostaining for all pituitary hormones but positive nuclear immunostaining for steroid factor-1 or DAX-1 characteristic of gonadotrope differentiation, with evidence of gonadotropin production or gene expression at the mRNA level.
  • Gonadotropinomas are monoclonal in origin but the pathogenesis of these tumors is unknown and factors that stimulate clonal proliferation not yet determined.
  • A new pituitary oncogene, pituitary tumor transforming gene, has recently been found to be overexpressed in about two thirds of these tumors but it is also detected in all other pituitary tumor subtypes.
  • Alterations of tumor hormone receptors and local growth factors may also play a role in the tumor development and/or progression.
  • Transphenoidal surgery remains the principal therapy for the macroadenomas.
  • Radiosurgery using gamma knife, the linear accelerator, or proton beam therapy showed promising results, especially for controlling the residual or recurrent tumors.
  • Medical therapy with somatostatin analogs, dopamine agonists, and gonadotropin-releasing hormone agonists and antagonists are rarely effective in reducing tumor size.
  • Experimental therapy with intraoperative local chemotherapy or potential gene therapy requires further investigation.

  • [Title] The somatostatin analogue octreotide confers sensitivity to rapamycin treatment on pituitary tumor cells.
  • Rapamycin and its analogues have significant antiproliferative action against a variety of tumors.
  • Here, we investigated this model using the somatostatin analogue octreotide as a tool to decrease levels of activated Ser(473)-phosphorylated Akt (pAkt-Ser(473)) in pituitary tumor cells that express somatostatin receptors.
  • Octreotide potentiated the antiproliferative effects of rapamycin in immortalized pituitary tumor cells or human nonfunctioning pituitary adenoma cells in primary cell culture, sensitizing tumor cells even to low rapamycin concentrations.
  • Combined treatment of octreotide and rapamycin triggered G(1) cell cycle arrest, decreasing E2F transcriptional activity and cyclin E levels by increasing levels of p27/Kip1.
  • These findings show that adjuvant treatment with a somatostatin analogue can sensitize pituitary tumor cells to the antiproliferative effects of rapamycin.
