Feasibility and safety of weekly sequential epirubicin-paclitaxel as adjuvant treatment for operable breast cancer patients older than 70 years.

BACKGROUND

There are currently no internationally agreed recommendations for the management of adjuvant chemotherapy in women aged >70 years with high-risk breast cancer. The purpose of this study was to assess the feasibility and the tolerance of adjuvant weekly sequential epirubicin-paclitaxel combination in this setting.

PATIENTS AND METHODS

From 2005 to 2009, 59 women over 70 years of age with operable breast cancer and who required adjuvant chemotherapy were proposed weekly sequential epirubicin-paclitaxel chemotherapy schedule, and were prospectively registered. Compliance and treatment tolerance were studied. We also report preliminary results of disease-free survival (DFS) and overall survival (OS).

RESULTS

Weekly sequential epirubicin-paclitaxel was well tolerated. No grade 4 adverse event occurred. No secondary malignancy was observed. Compliance with chemotherapy was good: 95% of patients received the six planned cycles. After a median follow-up of 24 months, median DFS and OS were not reached, there were only three relapses, and two cancer-related deaths were reported.

CONCLUSION

This study conducted in patients over 70 years of age demonstrates the feasibility of weekly adjuvant chemotherapy including anthracyclines and taxanes in a sequential schedule. This regimen is safe in terms of hematologic, nonhematologic, and cardiac toxicities, and showed encouraging efficacy, justifying further studies in geriatric patients.
