Intraarterial induction chemotherapy in locally advanced stage III breast cancer

Abstract

Five‐year results are reported on 27 patients with locally advanced breast cancer treated by intraarterial induction chemotherapy followed by radiotherapy and/or surgery with subsequent adjuvant chemotherapy. The cyclic infusion chemotherapy regimen was given over 3 to 6 weeks using Adriamycin (doxorubicin), 5‐fluorouracil (S‐FU), vincristine, and methotrexate in daily rotation, Regional and systemic side effects were minimal and temporary except in two patients in whom some skin discoloration has remained. Local tumor control and 5‐year cures depended on two important factors: whether follow‐up mastectomy was used after initial local tumor regression; and whether the carcinoma was classified as “inflammatory” with pathologic evidence of tumor invasion of dermal lymphatics. Of 16 patients with noninflammatory carcinoma treated by chemotherapy, radiotherapy, and mastectomy local tumor eradication was achieved in 15 and 5‐year apparent cure in 11. Of six patients with noninflammatory carcinoma treated with chemotherapy and radiotherapy but no mastectomy 5‐year local control was achieved in only three and 5‐year apparent cure in three. Of five patients with pathologic inflammatory carcinoma local tumor control was achieved in only one and only this one patient has been a 5‐year survivor apparently tumor‐free.
