Carcinosarcoma

GISAR has an open and modular setup. It is sought to include as many German sarcoma and CS patients (i.e. sarcoma and CS patients treated in Germany) in the registry as possible. A basic data set should be collected on every included patient). In order to adress specific scientific questions, additionally detailed data can be collected in defined patient groups (e.g. effectiveness / adverse effects of systemic therapies in defined situations) within the context of sub-project add-on modules. This data collection can be prospective or retrospective depending on the sub-project

Endometrial cancer (EC) is the fourth most common cancer in United States women, and alarmingly, the frequency and mortality from EC continues to rise, in part due to the obesity epidemic. Obese women with EC have a 6.3-fold increased risk of death from this disease, as compared to their non-obese counterparts. Patients with advanced/recurrent EC are unlikely to be cured by surgery, conventional chemotherapy (paclitaxel + carboplatin is the standard first-line treatment), radiation, or a combination of these. Thus, new treatments for EC are desperately needed as well as a better understanding of the impact of obesity on EC biology and treatment. The purpose of this study is to test the safety of a combination of treatments, atezolizumab and ONC201, given based on body weight, to treat endometrial cancer. Using the combination of atezolizumab and ONC201, has not been approved by the Food and Drug Administration (FDA) for the treatment of endometrial cancer. This clinical trial will examine the treatment of atezolizumab + ONC201 in obese and non-obese subjects with metastatic/recurrent EC.
