The Effects of Exercise on Distress, Quality of Life, and Biomarkers in Ovarian Cancer Survivors

Inclusion Criteria: * Histologically or cytologically confirmed stage II-IV epithelial ovarian, fallopian tube, or peritoneal cancer. If site of origin cannot be specified, carcinoma of Mullerian origin may be included if most consistent with ovarian/fallopian tube/peritoneal origin rather than uterine origin. The following histologic epithelial cell types are eligible: serous adenocarcinoma, endometrioid adenocarcinoma, mucinous adenocarcinoma, clear cell carcinoma, mixed epithelial carcinoma, transitional cell carcinoma, malignant Brenner's tumor, undifferentiated carcinoma, carcinosarcoma, or adenocarcinoma not otherwise specified. Women with neoplasms of low malignant potential (borderline tumors) are not eligible. * Subjects must have no evidence of disease, as defined by their treating oncologist, and with normal CA-125 (=\< 35). * Subjects must have completed primary surgery and adjuvant chemotherapy for treatment of ovarian, fallopian tube, of peritoneal cancer within one to six months of screening. Maintenance therapy will be allowed as long as the participant is in clinical remission- including hormonal agents, anti-angiogenesis agents, PARP inhibitors, and immunotherapy. Prior radiation therapy is allowed, as long as it has been completed within one to six months of screening. Subjects may have received prior therapies (including surgery, chemotherapy, radiation therapy) for other malignancies in the past. * Eastern Cooperative Oncology Group (ECOG) status of 0, 1, or 2. * Pregnancy and the need for contraception: \* Participants with ovarian cancer have undergone hysterectomy with removal of ovaries and tubes as part of surgical treatment, and therefore do not have the potential to become pregnant. * Ambulatory. * Ability to understand and the willingness to sign a written informed consent document. * Individuals participating in most other clinical trials are eligible provided their enrollment in the other trial does not impair their ability to participate in the physical activity interventions and study assessments required in this trial. The other clinical trial must not be a behavioral intervention trial. Exclusion Criteria: * Subjects who have had primary surgery, chemotherapy and/or radiation therapy within 4 weeks prior to screening. Subjects may have received other surgeries not performed for primary treatment (for example, removal of intraperitoneal port, laparoscopic cholecystectomy, etc.) within 1 month of screening as long as they do not have post-operative restrictions that would preclude participating in a moderate intensity exercise program once enrolled in the clinical trial. * Self-reported inability to walk at least 2 blocks (at any pace). * Prior brain metastasis is not an exclusion, as long as subject is in clinical remission. * Uncontrolled or concurrent illness including, but not limited to: unstable angina pectoris, recent (within six months) myocardial infarction, uncontrolled cardiac arrhythmia, uncontrolled congestive heart failure, hypertrophic obstructive cardiomyopathy, uncontrolled hypertension (systolic \> 200, diastolic \> 120), conditions (cardiovascular, respiratory, or musculoskeletal disease or joint problems) that preclude moderate physical activity. Subjects with a history of cardiac arrest, or those with moderate/severe aortic or mitral stenosis may be eligible if their treating physician determines that moderate physical activity is safe. Moderate arthritis that does not preclude physical activity is not a reason for ineligibility. Individuals with lymphedema or peripheral neuropathy will not be excluded. They will be evaluated by the exercise physiologist for safety and modifications to the exercise prescription will be made as appropriate. * Psychiatric illness/social situations that would limit compliance with study requirements. * Already physically active \> 90 minutes per week of moderate exercise.
