There has been a significant body of evolving evidence supporting physical activity (PA) and diet interventions to improve health outcomes and quality of life in cancer patients and survivors (1,2). Weight-management interventions also suggest positive impacts on health in this population (3,4). We acknowledge that strong evidence for the benefits of these interventions is largely demonstrated for breast and prostate cancer survivors (5,6), and evidence is limited for survivors of hematological, gastrointestinal, lung, and gynecological cancers. Our goal here is to provide guidance regarding research design and rigor that will strengthen and advance the current evidence base.
