Background: Four cycles of AC have been accepted as the standard chemotherapy in breast cancer. In the present randomized study we aimed to assess the efficacy of adjuvant etoposide + cisplatin (EP) combination following four cycles of standard adriamycin + cyclophosphamide (AC) in prernenopausal patients with operable breast cancer and axillary lymph node metastasis.
Patients and methods: Premenopausal patients with positive axillary lymph nodes following curative modified radical mastectomy were randomized to either four cycles of AC (82 patients) or four cycles of AC + two cycles of EP (83 patients).
Results. Median follow-up is 72 months. All randomized and eligible patients are included in the analysis (AC: 80 patients, AC + EP: 78 patients). The five-year disease-free survival (DFS) for the AC + EP group was significantly better when compared to AC group (45.5% vs. 30.4% P= 0.048). Again, the five-year overall survival (OS) of the whole group was in favor of AC + EP arm, though without statistical significance (68.6% vs. 59.l% P= 0.247).
Conclusion: Two cycles of EP following four cycles of AC decreased the relapse rate in operable breast cancer patients.
