Efficacy of anthracyclines and paclitaxel as first line chemotherapy in patients with visceral metastases of breast cancer.

Abstract：

BACKGROUND:Anthracyclines combined with paclitaxel are one of the most active schedules in patients with advanced breast cancer: response rates range from 40 to 80%, considering all metastatic sites (visceral and soft tissues). We performed a non-randomized phase II trial with anthracyclines/paclitaxel combination to evaluate response and toxicity only in patients with visceral metastases. METHODS:Twenty-seven patients (median age 50 years; range 30-72) with visceral metastases of breast cancer were enrolled in this study. Overall, 11 patients had lung metastases (41%), 10 liver (37%), 4 liver-lung metastases (15%) and 2 peritoneal carcinosis (7%). 7 patients had received adjuvant anthracycline-based chemotherapy (26%) and 10 patients adjuvant CMF combination chemotherapy (37%); 10 patients (37%) received hormonal therapy for advanced disease. Treatment schedules were: group A) 17 patients, Adriamicyn 50 mg/m2 on day 1 i.v. bolus and Paclitaxel 175 mg/m2 on day 2 i.v. 3 hours infusion, every 3 weeks; group B) 10 patients, epirubicin 90 mg/m2 on day 1 i.v. bolus and paclitaxel 200 mg/m2 on day 2 i.v., 3 hours infusion, every 3 weeks. The number of cycles administered was 141 with a median of 5 (range 3-9). RESULTS:All patients were evaluable for response and toxicity. The objective response rate was 59% - 16 patients - (15% complete and 44% partial remission), 95% C.I. 40.7-77%; 10/17 in group A and 7/10 in group B. Stable disease 30% (8 patients) and progressive disease 11% (3 patients). The median duration of response was 5 months (range 1-16); median time to progression 13 months (range 3-18) and median survival 17 months (range 4-24). The main toxicity was neutropenia, occurred in 16 patients (59%; grade IV in 7 patients, of whom 2 febrile neutropenia, and grade III in 9 patients); grade III gastrointestinal toxicity in 2 patients; grade III neurological toxicity in 1 patient; grade III stomatitis in 2 patients. No congestive hearth failure or treatment death related was observed. CONCLUSIONS:These schedules of anthracyclines and paclitaxel confirmed their efficacy in metastatic breast cancer even in patients with visceral disease. Neutropenia was the main toxicity; grade IV neutropenia was more frequently observed in epirubicin/paclitaxel arm.
