Background: In 2005 the Dutch national guidelines for treatment of breast cancer were updated. From then onwards, patients with operable breast cancer, who formerly received four cycles of adjuvant chemotherapy with doxorubicin/cyclophosphamide (AC), were treated with five cycles of 5-fluorouracil/epirubicin/cyclophosphamide (FEC), based on data suggesting survival benefit. Primary objective: evaluation of the effect on quality-of-life and trainability after four AC versus five FEC cycles of polychemotherapy. Secondary objective: evaluation of the effectiveness of an 18-week training programme for breast cancer survivors. Methods: A prospective cohort study design was used, comparing two chemotherapy regimens historically. The first cohort (group 1) received 4AC (A 60 mg/m2, C 600 mg/m2) (n=25) and the second cohort (group 2) received 5FEC (F 500 mg/m2, E 90 mg/m2, C 500 mg/m2) (n=50) adjuvant polychemotherapy. Both groups completed an 18-week high-intensity strength-training programme. Outcome measures were changes in quality-of-life (EORTC-QLQ-C30, MFI-20), muscular strength (one-repetition maximum; leg press) and cardiopulmonary function (VO2max) between baseline and follow-up. Results: Between March 2002 and February 2006, 75 female subjects with breast cancer participated in this study. Baseline characteristics were similar in both groups. After completing the training programme, both groups showed a significant improvement in all outcome measures. No significant differences in changes of the EORTC-QLQ-C30 and MFI-20, one repetition maximum of the leg press and the VO2max between the two groups were demonstrated. Conclusion: After adaptation of the Dutch national breast cancer treatment guidelines, patients received prolonged and increased doses of anthracyclines. This, however, did not result in a difference in the baseline situation before rehabilitation and in training response, nor in quality of life between the two groups.
