||Young Kim, MD
This randomized phase III trial studies whether changes in diet and physical activity can increase the length of survival without the return of cancer (progression-free survival) compared with usual care in patients with previously treated stage II, III, or IV ovarian, fallopian tube, or primary peritoneal cancer. A healthy diet and physical activity program and counseling may help patients make healthier lifestyle choices. It is not yet known whether changes in diet and exercise may help increase progression-free survival in patients with previously treated cancer.
- Patients with a histological diagnosis of epithelial ovarian cancer, fallopian tube or primary peritoneal carcinoma, clinical stage II, III or IV at diagnosis
- Patients must have completed all primary chemotherapy and consolidation therapy (if administered) at least 6 weeks, and no more than 6 months and 2 weeks, prior to enrollment and must be in complete remission; consolidation therapy is defined as any chemotherapy or biological therapy used for a patient who has completed at least four courses of primary chemotherapy and had documented complete remission prior to initiation of such chemotherapy (chemo) or biological therapy
- Patients must not be currently enrolled in an ongoing (participating for 6 months or longer) medically prescribed diet or physical activity regimen.
- Patients who are currently undergoing treatment (primary or consolidation) for stage II, III or IV ovarian, fallopian tube or primary peritoneal cancer or who completed treatment less than six weeks ago
- Patients diagnosed with chronic disease/illness precluding their participation (i.e., diabetics receiving insulin, myocardial infarction or unstable angina within previous 6 months, chronic hepatitis, rheumatoid disease, renal or hepatic disease/dysfunction)
- Patients with a life expectancy of less than one year
In the intervention group, participants receive a dietary intervention designed to promote increased levels of plasma carotenoids, control weight, and to ensure adequacy of micronutrient intake. Participants also undergo a physical activity intervention comprising a moderately low aerobic regimen to raise the usual activity level. Participants also undergo face-to-face counseling, receive educational materials and counseling focused on how to read food labels to estimate grams of fat per serving and serving size, and undergo telephone counseling by a lifestyle intervention counselor twice a week for 4 weeks, then weekly for 2 weeks, twice a month for 5 months, monthly for the subsequent 6 months, and then once every other month for 12 months. Participants complete daily fat gram and step diaries at least three times per week.
In the non-intervention (comparator) group, participants receive a study notebook containing general study-related information. Participants are not asked to record diet or physical activity but are provided a single sample diary in their study notebook. Participants receive telephone contact on a sliding scale similar to the intervention group, but at less frequent intervals (22 versus 33 calls over the course of the intervention).
