Nutrition et prévention tertiaire des cancers. y a-t-il des recommandations ?

Despite their heterogeneity, numerous studies suggest that life style and diet might be involved in cancer recurrence. Data seems more robust in breast and colon cancer. Recently, two large randomized trials conducted in breast cancer patients confirmed the feasibility of dietary interventions after cancer treatment. Their methodology remains however somewhat flawed. Thus, because of poor level of evidence, it remains hazardous to recommend specific interventions in cancer survivors. Noteworthy, there is no evidence supporting the use of high-dose micronutrients in order to improve cancer outcomes. On the other hand, the benefits of weight control and regular physical activity are less debatable. No matter what, it would appear essential that we carry out clinical research with the aim of identifying sub-groups of patients the most likely to benefit from a given dietary intervention.
