  • Effect of Temozolomide in Patients with Metastatic Bronchial Carcinoids
  • 2013
  • In: Neuroendocrinology. - : S. Karger AG. - 0028-3835 .- 1423-0194. ; 98:2, s. 151-155
  • Journal article (peer-reviewed)abstract
    • Introduction: Metastatic bronchial carcinoids are rare neoplasms, where efforts of medical treatment so far have been disappointing. A previous study from our center indicated that temozolomide might be of value. Materials and Methods: All patients with progressive metastatic bronchial carcinoid treated with tennozolomide as monotherapy at our center between 2004 and 2010 (n = 31) were included in this retrospective study. 14 tumors were classified as typical and 15 as atypical carcinoids, whereas 2 tumors could not be classified. Temozolomide was given on 5 consecutive days every 4 weeks. Toxicity was evaluable in 28 of 31 patients, and 22 patients were evaluable by RECIST 1.1. Results: There were no complete responses. A partial response was seen in 3 patients (14%), stable disease in 11(52%) and progressive disease in 7 patients (33%). Median progression-free survival was 5.3 months and median overall survival was 23.2 months from the start of temozolomide. Toxcities grade 3-4 were noted in 4 patients, thrombocytopenia (n =3) and leukopenia (n = 1). Conclusion: Temozolomide as monotherapy shows activity in metastatic bronchial carcinoids. Regimens combining tennozolomide with other agents (e.g. capecitabine and/or bevacizumab, everolimus, radiolabeled somatostatin analogues) should be further studied in these patients.

  • Multiple and Secondary Hormone Secretion in Patients With Metastatic Pancreatic Neuroendocrine Tumours
  • 2016
  • In: Journal of Clinical Endocrinology and Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 101:2, s. 445-452
  • Journal article (peer-reviewed)abstract
    • CONTEXT:As a group, neuroendocrine tumors (NETs) secrete many different peptide hormones, yet heretofore each NET patient is typically thought to produce at most one hormone that causes a distinct hormonal syndrome. A minority of patients have multiple hormones at diagnosis and may also develop secondary hormone secretion at a later stage.OBJECTIVES:The objectives of the study were to determine the frequency and to describe the impact of multiple and secondary hormone secretion in sporadic gasteroenteropancreatic NET patients.DESIGN, SETTING, AND PARTICIPANTS:This was a retrospective analysis of patients (n = 972) with gasteroenteropancreatic NET treated at Uppsala University Hospital, Uppsala, Sweden. Patients with the secretion of multiple hormones at diagnosis and/or those developing secondary hormone secretion during the disease course were identified and studied in further detail.RESULTS:In pancreatic NETs (PNETs), a total of 19 of 323 patients (6%) had secretion of multiple hormones at diagnosis, and 14 of 323 (4%) had secondary changes during the disease course. These phenomena occurred exclusively in patients with an advanced disease stage, and secondary hormones were detected in a close time span with progressive disease. Patients with secondary insulin hypersecretion had increased morbidity as well as reduced survival (P < .002). In contrast, multiple and secondary hormone secretion was rarely seen in NETs of the small intestine with 0 and 1 of 603 cases, respectively.CONCLUSION:Diversity of PNET hormone secretion either at diagnosis or during the disease course occurred in a minority of patients (9.3%). These phenomena had a major impact on patient outcome both through increased morbidity and mortality. Our results support that patients with metastatic PNETs should be monitored for clinical symptoms of secondary hormone secretion during the disease course.
