RATIONALE: Cardiotoxicity is a troubling long-term side effect of chemotherapy cancer treatment, affecting therapy and quality of life (QOL). Exercise is beneficial in heart failure (HF) patients and in cancer survivors without HF, but has not been tested in cancer survivors with treatment induced HF. METHODS: We present case studies for two survivors: a 56-year old female Hodgkin's lymphoma survivor (Pt 1) and a 44-year old male leukemia survivor (Pt 2). We conducted a 16-week exercise program with the goal of 30 minutes of exercise performed 3 times per week at a minimum intensity of 50% heart rate reserve (HRR) or '12' rating of perceived exertion (RPE). RESULTS: Pt 1 improved from 11.5 minutes of exercise split over two bouts at an RPE of 14 to a 30 minute bout at an RPE of 15. Pt 2 improved from 11 minutes of exercise split over two bouts at an RPE of 12 to an 18 minute bout at an RPE of 12. Both improved in VO(2) peak (Pt 1: 13.9 to 14.3 mlO(2)/kg/min; Pt 2: 12.5 to 18.7 mlO(2)/kg/min). Ejection fraction increased for Pt 2 (25-30% to 35-40%) but not for Pt 1 (35-40%). QOL as assessed by the SF-36 Physical Component Scale (PCS) improved from 17.79 to 25.31 for Pt 1 and the Mental Component Scale (MCS) improved from 43.84 to 56.65 for Pt 1 and from 34.79 to 44.45 for Pt 2. CONCLUSIONS: Properly designed exercise interventions can improve physical functioning and quality of life for this growing group of survivors.
