Purpose Immune checkpoint inhibitors have opened a new scenario in the treatment of cancer. These agents can elicit adverse events, which may affect different systems and organs, including the endocrine system. The aims of this study were to evaluate the impact of the anti-PD-1 molecules nivolumab and pembrolizumab on endocrine toxicity and on patient outcome. Methods A retrospective and multicentre study was designed, which involved a total of 251 patients affected by different tumors (mostly non-small cell lung cancer, 68.92% and melanoma, 24.30%) and treated with the PD-1 inhibitors nivolumab (61.35%) or pembrolizumab (38.65%) for up to 60 months. Clinical and biochemical data were recorded until July 31, 2020. Results Endocrine toxicity occurred in 70 out of 251 patients (27.89%). It was mostly related to thyroid dysfunction and in 75% of cases occurred within 6 months from the beginning of therapy. A previous endocrine morbidity and female gender were predictors of endocrine toxicity. There was no association between endocrine dysfunction and patient outcome. However, when all toxicities (i.e., endocrine and non endocrine) were considered, a significant association with progression-free survival and overall survival was found. Conclusions Thyroid alterations are frequently observed in cancer patients treated with anti PD-1 drugs, particularly in women and in the presence of a previous endocrinopathy. We suggest that regular thyroid assessment should be performed in these patients, especially in the first months of therapy. Finally, the onset of side effects, related to anti PD-1 agents, appears to be associated with a better outcome.

Background The aim of the study is to highlight the psychological aspects involved in patients with advanced melanoma and to describe the differences between subjects who are positive and negative for the BRAFv600e genetic mutation, a variable that leads to a different medical approach to cancer therapy. The hypothesis is that following knowledge of the genetic mutation and the therapeutic possibilities inherent to it, mutation positive patients (BRAF+) exhibit fewer negative psychological reactions than negative patients (BRAF-) at the time of diagnosis. Methods The tests used (SF-12, MHQ) were administered at the time of diagnosis and after three months. Results The main findings suggest a greater impairment of quality of life at T1 than at T0, regardless of the mutation; BRAF mutated patients show more favourable scores at diagnosis and a reversal of the trend at three months after diagnosis. Conclusions The results obtained, in line with the literature under review, show a significant general psychological distress in the present oncological sample, suggesting the importance of a psychological, as well as medical, care of the patient and the family.

Systemic mastocytosis (SM) encompasses a heterogeneous group of clonal disorders characterized by abnormal expansion of mast cells (MCs). Beyond KIT and other genes recurrently mutated in myeloid neoplasms, several genetic variants have been described as predisposing to the development of the disease and influencing its clinical phenotype. Increased copy number variants of the TPSAB1 gene were identified as a cause of nonclonal elevated tryptasemia and defined as hereditary α-tryptasemia (HαT). Moreover, HαT is enriched in patients with SM, where it can affect the incidence of mediator-related symptoms.In a multicenter data set of 444 patients with MC disorders, we aimed to investigate the clinical correlates of germline TPSAB1 copy number gains.Droplet digital PCR was performed in all cases to ascertain the presence of HαT. Clinical history along with blood values and bone marrow examination were analyzed.We confirmed a higher incidence of HαTThese findings on a large patient series support and extend previous data, and suggest that knowledge of HαT status may be useful for personalized management of patients with SM.
