Molecular Staging of Endometrial Cancer

Study Summary

This study, sponsored by NCI and the Gynecologic Oncology Group (GOG), will collect tissue samples from women with cancer of the endometrium (lining of the uterus). Researchers will use the samples to learn more about endometrial cancer and develop new treatments and methods of prevention. Women with endometrial cancer who are suitable candidates for surgery and who have not had prior retroperitoneal surgery or pelvic or abdominal radiation therapy may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood tests, and endometrial biopsy (surgical removal of a small tissue sample) or dilation and curettage (D \& C). Participants will undergo hysterectomy (surgery to remove the uterus) along with removal of both fallopian tubes and ovaries. This is the standard surgical treatment for endometrial cancer. Lymph nodes in the pelvis near the main blood vessel in the abdomen are also removed to determine if the disease has spread to these nodes. If cancer is found involving other sites, the cancer in those areas may also be removed; examination of the tissues will determine if further therapy beyond surgery is needed. Before surgery, patients will complete a 20-minute questionnaire that includes questions about their background, reproductive history, menstruation and menopause, certain surgeries, birth control pills and hormone replacement therapy, other drugs and medicines, weight and height, smoking, medical history, and family history of cancer. Some of the tissue removed during surgery, plus a urine sample collected from a catheter bag during surgery, and blood drawn before surgery and at follow-up visits 6 weeks and 3 years after surgery, will be sent to the GOG Tissue Bank in Columbus, Ohio. This bank stores, processes, and distributes biological specimens from patients that agree to participate in studies conducted by the GOG. Patients will have follow-up visits 6 weeks after surgery, then every 6 months fo
