Abstract: | Purpose:In a previous phase I trial we evaluated the toxicity anddetermined the maximum tolerated doses of the docetaxel (D)–epirubicin(Epi) combination. We conducted a multicenter phase II study to evaluate theefficacy and tolerability of this regimen as front-line treatment in womenwith advanced breast cancer (ABC).Patients and methods:Fifty-four women with ABC stage IIIB (4patients) or IV (50 patients) received front-line treatment with Epi 70mg/m2 on day 1 and D 90 mg/m2 on day 2. The median agewas 55 years, performance status (WHO) was 0–1 in 49 patients andvisceral disease was present in 45 (83%).Results:All patients were evaluable for toxicity and 50 forresponse. In an intent-to-treat analysis complete remission was observed in5(9%) patients, partial remission in 31 (57%) (overall responserate 66%, 95% confidence interval: 54%–79%),stable disease in 9 (17%) and disease progression in 9 (17%).After a median follow-up of 11.5 months, the median duration of responses was8 months, the median time to disease progression 11.5 months and the mediansurvival has not yet been reached. The probability of one-year survival was65%. Three hundred six cycles of treatment were administered (median6 cycles per patient). Grade 3 and 4 neutropenia was observed in 8(15%) and 31 (57%) patients, respectively, and febrileneutropenia in 19 (35%). Prophylactic rh-G-CSF was used in 45(83%) patients or 226 (74%) cycles. Other hematologic ornon-hematologic toxicities were usually mild. In five (9%) patients theleft ventricular ejection fraction (LVEF) was decreased by more than10% with the treatment. Two patients died during the treatment ofrespiratory failure without associated neutropenia.Conclusions:The combination of docetaxel–epirubicin is aneffective and well tolerated front-line treatment in patients with ABC. |
