  • Long-Term Outcome and MGMT as a Predictive Marker in 24 Patients With Atypical Pituitary Adenomas and Pituitary Carcinomas Given Treatment With Temozolomide
  • 2015
  • Ingår i: Journal of Clinical Endocrinology & Metabolism. - : Oxford University Press. - 0021-972X .- 1945-7197. ; 100:4, s. 1689-1698

    • Context/Objective: Locally aggressive pituitary tumors (LAPT) and pituitary carcinomas respond poorly to conventional therapy and cytotoxic drugs. Temozolomide (TMZ) is an oral alkylating drug with good tolerability, approved for treatment of malignant gliomas. The experience of its use in pituitary tumors is limited. Design and Setting: We report on 24 patients with aggressive pituitary tumors (16 LAPTs, 8 carcinomas) treated with TMZ for a median of 6 months (range 1-23). Follow-up ranged from 4 to 91 months with a median of 32.5 months. 19/24 tumors were hormone secreting (PRL 9, ACTH 4, GH 4, GH/PRL 2). Ki-67 was 2-50% in LAPTs, and 5-80% in carcinomas. Main Outcome: Response to TMZ and the association with tumor expression of O6-methylguanine DNA methyltransferase (MGMT), MLH1, MSH2, and MSH6, examined by immunohistochemistry. Results: Complete tumor regression occurred in two carcinomas and persisted at follow-up after 48 and 91 months, respectively. Partial regress of tumor mass ranging from 35% to 80% occurred in 5 LAPTs and 2 carcinomas. Another patient with LAPT had a 71% decrease in prolactin levels without change in tumor volume. Three LAPTs could not be evaluated. Median MGMT staining was 9% (5-20%) in responders vs 93% (50-100%) in nonresponders. Loss of MSH2 and MSH 6 was observed in a single patient who had a rapid development of resistance to TMZ. Conclusions: This study shows that TMZ is a valuable treatment option for patients with uncontrolled pituitary tumors. The data suggest that tumoral MGMT staining below 50% is associated with a high likelihood of treatment response.

  • GLUCOCORTICOIDS AND SARCOIDOSIS: A LONGITUDINAL STUDY ON THE EFFECTS ON CORTICAL AND TRABECULAR BONE
  • 2015
  • Ingår i: Sarcoidosis Vasculitis and Diffuse Lung Diseases. - : MATTIOLI 1885. - 1124-0490. ; 32:1, s. 63-69
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Glucocorticoid induced osteoporosis is a well-known side effect of glucocorticoid treatment. In sarcoidosis the impact on bone by glucocorticoid treatment is complex due to hormonal disturbances of calcium and vitamin-D, which by itself may cause bone loss. In this study we aimed to investigate the longitudinal impact of glucocorticoids on cortical and trabecular bone in patients with mild, recently diagnosed sarcoidosis.Methods: Ten patients (8 females; mean age 44 (+/- 13)) were studied during one year of glucocorticoid treatment. The assessment of mainly cortical to purely trabecular bone was made by dual X-ray absorptiometry (DXA) of the spine and hip, quantitative ultrasound of the calcaneus, and magnetic resonance relaxometry of the spine and calcaneus. Bone and hormonal measurements were performed at baseline, after 3, 6, and 12 months, and baseline, 3 weeks and 3 months, respectively.Results: DXA of the spine, decreased from baseline at 6 months (P=0.01). R2 of the calcaneus decreased with time (B: -3.6; P=0.03). In the females (n=8) there was a significant decrease in DXA of the spine when comparing 3 months and 6 months (P=0.03), and 3 months and 12 months (P=0.02) and a decrease in R2 of the calcaneus from baseline to 12 months (P=0.01). There was no change in hormonal levels.Conclusion: Treatment of initial mild sarcoidosis with dose tapered glucocorticoid therapy only mildly affects the final trabecular and cortical bone and hormone levels. Dose tapering is an important part in glucocorticoid therapy, likely contributing to the mild effects on bone observed in this study.

  • Overall and Disease-Specific Mortality in Patients With Cushing Disease: A Swedish Nationwide Study
  • 2019
  • Ingår i: Journal of Clinical Endocrinology and Metabolism. - : ENDOCRINE SOC. - 0021-972X .- 1945-7197. ; 104:6, s. 2375-2384
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Whether patients with Cushing disease (CD) in remission have increased mortality is still debatable. Objective: To study overall and disease-specific mortality and predictive factors in an unselected nationwide cohort of patients with CD. Design, Patients, and Methods: A retrospective study of patients diagnosed with CD, identified in the Swedish National Patient Registry between 1987 and 2013. Medical records were systematically reviewed to verify the diagnosis. Standardized mortality ratios (SMRs) with 95% CIs were calculated and Cox regression models were used to identify predictors of mortality. Results: Of 502 identified patients with CD (n = 387 women; 77%), 419 (83%) were confirmed to be in remission. Mean age at diagnosis was 43 (SD, 16) years and median follow-up was 13 (interquartile range, 6 to 23) years. The observed number of deaths was 133 vs 54 expected, resulting in an overall SMR of 2.5 (95% CI, 2.1 to 2.9). The commonest cause of death was cardiovascular diseases (SMR, 3.3; 95% CI, 2.6 to 4.3). Excess mortality was also found associated with infections and suicide. For patients in remission, the SMR was 1.9 (95% CI, 1.5 to 2.3); bilateral adrenalectomy and glucocorticoid replacement therapy were independently associated with increased mortality, whereas GH replacement was associated with improved outcome. Conclusion: Findings from this large nationwide study indicate that patients with CD have excess mortality. The findings illustrate the importance of achieving remission and continued active surveillance, along with adequate hormone replacement and evaluation of cardiovascular risk and mental health.

  • The incidence of Cushing's disease : a nationwide Swedish study
  • 2019
  • Ingår i: Pituitary. - : Springer. - 1386-341X .- 1573-7403. ; 22:2, s. 179-186
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Studies on the incidence of Cushing’s disease (CD) are few and usually limited by a small number of patients. The aim of this study was to assess the annual incidence in a nationwide cohort of patients with presumed CD in Sweden.Methods: Patients registered with a diagnostic code for Cushing’s syndrome (CS) or CD, between 1987 and 2013 were identified in the Swedish National Patient Registry. The CD diagnosis was validated by reviewing clinical, biochemical, imaging, and histopathological data.Results: Of 1317 patients identified, 534 (41%) had confirmed CD. One-hundred-and-fifty-six (12%) patients had other forms of CS, 41 (3%) had probable but unconfirmed CD, and 334 (25%) had diagnoses unrelated to CS. The mean (95% confidence interval) annual incidence between 1987 and 2013 of confirmed CD was 1.6 (1.4–1.8) cases per million. 1987–1995, 1996–2004, and 2005–2013, the mean annual incidence was 1.5 (1.1–1.8), 1.4 (1.0–1.7) and 2.0 (1.7–2.3) cases per million, respectively. During the last time period the incidence was higher than during the first and second time periods (P < 0.05).Conclusion: The incidence of CD in Sweden (1.6 cases per million) is in agreement with most previous reports. A higher incidence between 2005 and 2013 compared to 1987–2004 was noticed. Whether this reflects a truly increased incidence of the disease, or simply an increased awareness, earlier recognition, and earlier diagnosis can, however, not be answered. This study also illustrates the importance of validation of the diagnosis of CD in epidemiological research.

  • Pituitary Metastases: a Nationwide Study on Current Characteristics with Special Reference to Breast Cancer.
  • 2019
  • Ingår i: The Journal of clinical endocrinology and metabolism. - : ENDOCRINE SOC. - 1945-7197 .- 0021-972X. ; 104:8, s. 3379-88

    • To investigate the contemporary presentation of pituitary metastases.Thirty-eight patients diagnosed with pituitary metastases 1996 to 2018 in Sweden.Pituitary metastases were confirmed by histopathology (n = 27) or considered highly likely due to radiological findings, including rapid tumor progression (n = 11). Medical charts were reviewed and sellar images re-examined centrally.Breast and lung cancer were the most common primary tumors, 45% and 21% of the patients. The pituitary was the only metastatic site in 9 patients. 67% of the breast cancers overexpressed HER2. 53% of the pituitary metastases from breast cancers appeared ≥10 years after diagnosis of the primary tumor. At presentation, 71% appeared to have ACTH deficiency, 65% had TSH deficiency, and 26% had diabetes insipidus. 47% of patients with morning cortisol <100 nmol/L vs 23% with cortisol ≥200 nmol/L reported fatigue, nausea/vomiting, loss of appetite, weight loss, myalgia and/or arthralgia. Sixteen patients had visual field defects, eight had diplopia. Intra- and suprasellar tumor growth was the most frequent finding. Initially, a pituitary adenoma was considered to be the etiology in 18% of the patients. Radiotherapy, pituitary surgery, and chemotherapy were used in 68%, 68% and 11% of the patients. One and 2 years after diagnosis of PM, 50% and 26% of the patients were alive.Pituitary metastases may be mistaken for pituitary adenomas and can appear late, especially in breast cancer. Breast cancers overexpressing HER2 seem prone to metastasize to the pituitary. Hypocortisolism, may be misdiagnosed as cancer-related malaise. An increased awareness of PM and undiagnosed pituitary failure can improve the management in these patients.
