Cardiac sarcoma is a lethal tumor with an EMS of 25 months. The tumor histology could be a possible predictor of better survival. Although selection bias may have been present, multimodality therapy (surgery, radiation therapy, and chemotherapy) was associated with improved survival.

Background Cancer‐associated thrombosis (CAT) is a major cause of mortality in cancer patients. Immune checkpoint inhibitors (ICIs) have been associated with multiple side effects including CAT. The aim of this study is to investigate risk factors and prognostic impact associated with CAT events during ICIs treatment. Methods This is a multi‐center retrospective study that included stage IV cancer patients treated with ICIs. Results We identified 552 cancer patients treated with ICIs. During follow‐up time, 58 (10.5%) patients developed 67 venous thromboembolism (VTE) events while on ICIs. Anticoagulation use at the time of ICIs treatment start was associated with significantly higher VTE incidence rate (IRR: 2.23). No significant difference in VTE IRR was observed depending on response to ICIs treatment, aspirin use, or Khorana VTE risk score. Melanoma as primary cancer, Khorana score, ECOG status, and anemia at baseline were able to predict mortality. Conclusions The incidence of CAT in stage‐IV cancer patients treated with ICIs was higher in our study compared to previous reports. Control group of patients who did not receive ICIs is needed for better identification of CAT risk factors. Khorana score was a good predictor of mortality but not CAT risk and needs to be further validated in a homogenous group of patients.

We made some recommendations for drug choices to avoid clinically important drug interaction.

Background: Immune thrombocytopenia (ITP) is an acquired disease characterized by thrombocytopenia secondary to autoantibodies against platelets. Here, we report the clinical characteristics of coronavirus disease 2019 (COVID-19)-induced ITP cases.Study Design and Methods: We retrospectively reviewed 3255 COVID-19 patients. COVID-19-induced ITP was diagnosed after excluding possible common causes. Bleeding severity was assessed based on the modified World Health Organization (WHO) bleeding severity score. Results: We identified 11 (0.34%) patients with COVID-19-induced ITP. Of all patients, 63.6% were males and the median age was 63 years. The median time from COVID-19 diagnosis to the onset of ITP was 10 days.Bleeding observed in 63.6% of the patients. Clinically significant bleeding (WHO Grade 3) occurred in single patient who required blood transfusion. Standard treatment with glucocorticoids and intravenous immunoglobulin (IVIG) was effective in achieving excellent response in most cases. Of all patients, complete response and response to treatment were achieved in 45.5% and 27.3% patients, respectively. The median time to ITP recovery was 4 days. Eltrombopag was used in three patients who relapsed. Four patients required mechanical ventilation, and none of them survived secondary to hypoxic respiratory failure. Conclusion: ITP secondary to COVID-19 usually presents after the first week of symptoms beginning. Most of our patients had WHO Grade 1-2 bleeding scores. Standard treatment with glucocorticoids and IVIG is effective in achieving an excellent response. The safety of eltrombopag is not very well established in COVID-19 patients, and additional studies are needed for a better safety profile.
