Prospective Study of Detection of Sarcopenia in Clinical Practice for Patient With Ovarian or Endometrial Cancer

This study is looking at how common muscle wasting (called sarcopenia — a serious loss of muscle mass and strength) is in women receiving chemotherapy for ovarian or endometrial (uterine) cancer, and whether it affects how they tolerate treatment. This is an observational study, meaning researchers will track patients but won't change their treatment. **You may be eligible if...** - You are 18 or older - You have been diagnosed with ovarian or endometrial cancer and are scheduled to receive chemotherapy - You have not had another cancer diagnosis in the past 5 years - You are enrolled in a social security or health insurance scheme **You may NOT be eligible if...** - You have ovarian or endometrial cancer that does not require chemotherapy - You have been recently diagnosed with another cancer (except skin or cervical cancer) - You have a pacemaker (which interferes with the body composition scan used in this study) Talk to your doctor to see if this trial is right for you.
