Diet Quality May Impact Ovarian Cancer Prognosis

the MPR take:

Females with healthy diets prior to an ovarian cancer prognosis may reduce mortality risk compared to women with poorer diets except in women with diabetes or a high waist circumference, a new study has shown in the Journal of the National Cancer Institute. Cynthia A. Thomson of Health Promotion Sciences, Canyon Ranch Center for Prevention and Health Promotion at the University of Arizona, Tucson, AZ, and researchers believe a healthy diet is related to a stronger immune system, which may help the patient respond more positively to chemotherapy. The study analyzed 636 cases of ovarian cancer occurring between 1993–1998, of which 90% were invasive cancers. Female patients had filled out dietary and physical activity questionnaires at least one year before their cancer diagnoses as part of the larger Women's Health Initiative study. Data showed women in the healthiest-eating group were 27% less likely to die of any cause after ovarian caner diagnosis vs. women in the poorest-eating group. Women with a history of diabetes and a waist circumference >34in did not demonstrate the survival benefit of a healthy diet as other women. Further, the association between diet quality and survival were not affected by the amount of exercise women got prior to the diagnosis.

The exceptions were women with diabetes or a high waist circumference, which is often linked to diabetes. A healthy diet before diagnosis may indicate a stronger immune system and, indirectly, the capacity to respond favorably to cancer therapy, said lead author Cynthia A.
