I hope the researchers will also consider looking at Response Rates to treatment between exercising groups and controls, even prior exercise (particularly in the weeks just before treatment) and treatment Response Rates (CR complete response, PR partial response, PFS progression free survival, and OS overall survival when applicable).

Can exercise, just prior to and during treatment, improve cancer treatment outcomes - Response Rates?  If so, this could move exercise beyond a good suggestion and into the realm of a reimbursable procedure for oncologists, who unfortunately infrequently prescribe exercise as a part of cancer treatment.

Response Rates, without adverse side effects, are what drive new drug development and new drug protocols.  We need to start viewing exercise as medicine, and one step in that direction is measuring Response Rates.
