To test these observations with a large, randomized clinical trial, an intervention that significantly impacts physical activity in these patients is needed. The Active After Cancer Trial (AACT) was a multicenter pilot study evaluating the feasibility of a telephone-based exercise intervention in a cooperative group setting. Sedentary (engaging in <60 min of recreational activity/week) breast and colorectal cancer survivors were randomized to a telephone-based exercise intervention or usual care control group. The intervention was delivered through the University of California at San Diego; participants received ten phone calls over the course of the 16-weeBreast cancer research and treatmentImpact of a telephone-based physical activity intervention upon exercise behaviors and fitness in cancer survivors enrolled in a cooperative group setting.PMC3353544U10 CA031946R01 CA149222Marshall JPierce JPHacker EShapiro CMeyerhardt JShockro LNewman VALigibel JACampbell NBarbier LPaskett ENajita JWood MfalseImpact of a telephone-based physical activity intervention upon exercise behaviors and fitness in cancer survivors enrolled in a cooperative group setting.Observational studies demonstrate an association between physical activity and improved outcomes in breast and colon cancer survivors.
