Combined chemotherapy-radiotherapy approach in locally advanced (T3b-T4) breast cancer

SummaryCombined treatment modality was applied in 110 consecutive women with primary inoperable (T3b-T4) breast cancer. Treatment was started with four cycles of adriamycin plus vincristine (AV). This was followed in responders by high-energy radiotherapy (RT). At the end of combined therapy, patients in complete remission (CR) were randomized to either no further treatment or six more cycles of chemotherapy. AV induced objective response in 89% of patients (complete 15.5%, partial 54.5%, improvement 19%). At the end of RT, 81 of 98 (82.7%) patients responding to AV were classified in CR. The median duration of CR was 15 months. The median free interval was statistically prolonged by additional chemotherapy. The three-year survival was 52.8%. Altogether, present findings indicate that combined treatment modality has improved the three-year survival compared to the previous series treated with radiotherapy alone. However, to achieve a satisfactory control of T3b-T4 breast cancer a more aggressive and prolonged treatment is required.
