The efficacy of combined chemotherapy and radiotherapy in advanced non-metastatic breast cancer.
Thirty-five patients with locally advanced (inoperable) breast cancer have been treated based on a regimen of chemotherapy-radiotherapy-chemotherapy. At the completion of all treatment a complete remission rate of 86% was achieved with acceptable toxicity. At a median follow-up of 24 months (range 4-60), relapse at the site of bulk disease occurred in 17% (10% isolated loco-regional relapse) and relapse at distant sites in 34%. The median relapse-free survival was 36 months and the median survival has not yet been reached. Following initial promising results in terms of loco-regional disease control in this group of high-risk patients, the protocol was extended to include 34 patients defined as having locally extensive disease. All patients in this subgroup had undergone a modified radical mastectomy and were categorized as (a) patients in whom the pre-operative clinical findings merited (in our opinion) inclusion in the category of locally advanced (inoperable) disease, (b) patients in whom the primary was operable but in whom extensive involvement of axillary nodes was found (greater than 10 nodes positive or greater than or equal to 70% nodes positive if less than 10 nodes found) and (c) patients without the above characteristics with a primary tumor greater than 8 cm. At a median follow-up of 23 months (range 4-48), loco-regional recurrence occurred in one patient (3%) but distant relapse occurred in 21%. Relapse-free and overall survival was not significantly different to that found in patients with locally advanced disease who did not undergo mastectomy.
