Abstract Background: Somatostatin analogs (SSA) are efficiently used to control central hyperthyroidism in patients with thyrotropin-secreting pituitary neuroendocrine tumor (TSH-PitNET). The aim of this study was to describe the frequency of thyrotropin (TSH) deficiency under SSA in patients with TSH-PitNET. Methods: We retrospectively recruited patients presenting a central hyperthyroidism due to TSH-PitNET. Inclusion criteria were patients treated in first, second or third line by short or long-acting SSA, with central hyperthyroidism before SSA. Patients treated by radiotherapy or dopamine agonist were excluded. TSH deficiency was defined by either a low FT4 or low FT4 and FT3, associated with non-elevated TSH concentrations during SSA therapy. We analyzed the frequency of TSH deficiency and the characteristics of patients with or without TSH deficiency. Results: 46 patients were included in the study. SSA were used as the first-line therapy in 21 of 46 patients (46%). Central hyperthyroidism was controlled in 36 of 46 patients (78%). TSH deficiency appeared in 7 of 46 patients (15%), after a median time of 4 weeks (4–7) after the starting of SSA, and for a median duration of 3 months (2.5–3). The TSH deficiency occurred after 1 to 3 injections of long-acting SSA. There were no differences in terms of clinical and hormonal features and size of adenomas between patients with or without TSH deficiency. Conclusions: In patients with central hyperthyroidism due to TSH-PitNET, SSA can induce TSH deficiency. Thyrotropic function should be assessed before each injection of SSA in order to adapt the frequency of injection when control of thyrotoxicosis rather than tumor reduction is purpose of the treatment.

Tsh Deficiency

Objective Somatostatin receptor ligands (SRL) are useful to control central hyperthyroidism in patients with thyrotropin-secreting pituitary adenoma (TSH pituitary adenoma). The aim of this study was to describe the frequency of thyrotropin deficiency (TSH deficiency) in patients with TSH pituitary adenoma treated by SRL. Design Retrospective study. Methods Patients with central hyperthyroidism due to TSH pituitary adenoma treated by short or long-acting SRL were retrospectively included. TSH deficiency was defined by a low FT4 associated with non-elevated TSH concentrations during SRL therapy. We analysed the frequency of TSH deficiency and the characteristics of patients with or without TSH deficiency. Results Forty-six patients were included. SRL were used as the first-line therapy in 21 of 46 patients (46%). Central hyperthyroidism was controlled in 36 of 46 patients (78%). TSH deficiency appeared in 7 of 46 patients (15%) after a median time of 4 weeks (4–7) and for a median duration of 3 months (2.5–3). The TSH deficiency occurred after one to three injections of long-acting SRL used as first-line therapy in 6/7 cases. There were no differences in terms of clinical and hormonal features, size of adenomas or doses of SRL between patients with or without TSH deficiency. Conclusions SRL can induce TSH deficiency in patients with central hyperthyroidism due to TSH pituitary adenoma. Thyrotropic function should be assessed before the first three injections of SRL in order to track TSH deficiency and reduce the frequency of injections when control of thyrotoxicosis rather than tumour reduction is the aim of the treatment.

Cisplatin has had only minimal activity when used as second- and third-line chemotherapy for metastatic breast cancer (MBC). There have been no phase II studies in the United States evaluating cisplatin in patients with MBC with no prior chemotherapy. We therefore treated 20 consecutive patients with cisplatin 30 mg/m2/d for four days every 3 weeks for a maximum of six courses. We obtained partial responses in nine of 19 evaluable patients (47%), with responses in liver, lung, and soft tissue indicator lesions. Our data suggest that cisplatin has substantial single-agent activity as front-line therapy in MBC, and should be considered for inclusion in first-line combination chemotherapy regimens.

Abstract To evaluate clinical and biological features, treatments and outcome of patients(pts) with Systemic Mastocytosis(SM). A retrospective study (1995–2006) about pts with SM admitted in 14 Italian hematology divisions in tertiary cares or university hospitals. 30 cases of SM were collected(median age 62 y.o.; M/F 14/16) and classified according to the WHO criteria: Mast Cell Leukemia in 14 pts, Aggressive SM in 12 and Indolent in 3; the remaining one had SM with associated clonal non-mast cell-lineage hematologic disease. Skin was the principal extramedullary organ involved (19 pts) followed by spleen(15), liver(13), and cardiovascular system(12). Molecular biology studies were performed in 22 pts: 15 showed the c-kit point mutation D816V; in another patient a different c-kit mutation was found while in 3 pts additional gene defects and karyotype abnormalities were recognized. Treatments were heterogeneous, and the same patient could have received different therapies after failure of the previous one. Imatinib(400 mg/day) was used in 17 pts (11 as first line therapy, 5 and 1 as second and third line respectively); interferon-alpha(3×3 MU s.c. weekly) was employed in 7 patients(4 as first line therapy, 2 as second and 1 as third line); 2-CDA(0.14 mg/kg) was administered in 3 pts(1 as first, 1 as second and 1 as third line therapy); 2 patients underwent HSCT as second and third line respectively. Data about response to treatment are reported in the table. The overall response rate to imatinib was of 30%, registering 1 complete remission(CR) and 4 partial remissions. All but one responsive patients did not present c-kit point mutation. Three pts(10%) died for progression of SM; a fourth patient in CR died for accidental causes. The actuarial Kaplan-Meier curve at 10 years showed an overall-survival of 87%. Conclusions: SM is a rare disease, characterized by severe and life-threatening mediator-related symptoms but with a low mortality rate. D816V c-kit mutation is frequent and associated with resistance against imatinib: only 1 patient showed a CR. Of note 2-CDA has shown interesting clinical response: all 3 treated pts showed a clinical improvement. Because of the rarity of SM, an effective standard of care is lacking. More data are needed to find new and successful therapeutic strategies; it is possible that new tyrosine kinase inhibitors could allow to achieve clinical and molecular remission of disease, crossing resistence to imatinib due to c-kit mutation, in order to improve above all quoad valitudinem prognosis of these pts.

Introduction: Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma in the Western hemisphere. Patient characteristics and burden of FL are incomplete and vary from previous studies. This study evaluated patient profile, including patient characteristics, treatment patterns, and duration using real-world data. Methods: Using the Truven MarketScan® databases, patients with FL who were newly initiated with FL indicated regimens were identified from 1/1/2010-12/31/2013 (initial treatment identification period). Patients were selected if they were ≥18 years old, had 1 FL ICD-9 code (202.0) as primary or secondary diagnosis, at least 1 FL commonly prescribed systemic anti-cancer therapy after the diagnosis, and did not use any FL indicated regimen in the past 6 months prior to first agent included in the initial treatment identification period. These patents were followed ≥3 months or to June 30, 2018. Primary outcomes were the distribution of regimens by line, the number of patients who switched from first- to second-line therapies, and from second- to third-line therapies. The treatment duration by line of therapy and regimen were also analyzed. Discontinuation was defined as 3 months without receiving a regimen after treatment. Results: This study identified 4,970 patients who initiated treatment for FL. Of these patients, 48.1% were female (n=2,390), with a mean age of 62.0 (SD: 14.0) years. The average follow-up time was approximately 2 years (median: 733 days). In this analysis, 4,970 patients with FL received first-line therapy for 153 days (median: 94 days), 1,985 received second-line therapy (39.9% of patients who received first-line therapy) for 208 days (median: 80 days), and 664 received third-line therapy (13.4% of patients who received first-line therapy) for 117 days (median: 43 days). Of the 4,970 patients on first-line therapy, 453 (9.1%) remained on first-line therapy, 2,532 (51.0%) discontinued treatment, and 1,985 (39.9%) patients switched to the next line of therapy during the follow-up period. Of the 1,985 patients who switched to second-line therapy, 328 (16.5%) remained by the end of follow-up period, 993 (50.0%) discontinued, and 664 (33.4%) switched to the next line of therapy during the follow-up period. Of the 664 patients who switched to third-line therapy, 125 (18.8%) remained, 269 (40.5%) discontinued, and 270 (40.7%) switched to the next line of therapy. The most common first-line regimens in descending order received by patients were rituximab (n=1,478, 29.7%), R-CHOP (n=1,368, 27.5%), BR (n=1,050, 21.1%), R-CVP (n=371, 7.5%), and FCR (n=63, 1.3%). Second-line treatment regimens were (N=1,985) rituximab (n=992, 50.0%), BR (n=202, 10.2%), R-CHOP (n=138, 7.0%), and R-CVP (n=120, 6.1%). Third-line treatment regimens were (N=664) rituximab (n=228, 34.3%), BR (n=91, 13.7%), R-CHOP (n=75, 11.3%), cyclophosphamide (n=35, 5.3%) and R-CVP (n=31, 4.7%). Conclusion: This data set describes the percentage of patients that transition from first- to second-line and second- to third-line treatment for FL. The primary regimens used across the treatment lines conform to those recommended by the NCCN guidelines. In addition, smaller numbers of non-recommended regimens were reported.

Aim: To conduct a retrospective analysis of electronic medical record data to understand real-world treatment patterns and overall survival (OS) in patients with metastatic non-small-cell lung cancer (NSCLC). Materials & methods: We included n = 9656 adults (≥18 years) with metastatic NSCLC and no prior therapy. Data from 1 January 2013 to 31 January 2017 were analyzed. Results: Carboplatin plus paclitaxel was the most common first-line therapy (18.6%), and nivolumab was the most common second- (31.0%) and third-line (38.4%) therapy; 26.7% of all patients were untreated. Median OS from initial metastatic diagnosis was 11.1 months (95% CI: 10.8–11.5). Second-line immunotherapy extended OS by over 3 months versus second-line chemotherapy. Conclusion: Platinum-based therapy was the most common first-line therapy, and immunotherapy was the most common second- and third-line therapy. Median OS of patients with metastatic NSCLC was <1 year.
