Abstract

RATIONALE: Docetaxel and doxorubicin have produced a high degree of activity in previously untreated/treated patients with metastatic breast cancer (MBC). The efficacy of Taxotere (T) single agent as 2nd line chemotherapy is well established in large randomized phase III studies. OBJECTIVE: The objective of this study is to confirm the efficacy and safety of a combination of Taxotere with doxorubicin as 1st line chemotherapy in Indonesian MBC patients. TREATMENT AND METHOD: Eighteen patients age < or = 70 years with advanced or metastatic breast cancer (MBC) with no prior taxane chemotherapy or prior cumulative doxorubicin (D) of no more than 250 mg/m2 and no heart disease were enrolled in this phase II study of D (50 mg/m2) IV bolus followed one hour later by Taxotere (T) 60 mg/m2 IV infusion over 1 hour every 3 weeks for 6 cycles treatments. A 3-day oral corticosteroid premedication was administered starting one day before the infusion of each cycle. Left ventricular ejection fraction (LVEF) was evaluated at baseline and after cycle 6. PATIENTS CHARACTERISTICS: 18 patients (pts) have been treated with 108 cycles administered. Median age was 46 years (31-58), WHO PS 0 = 50%, 1 = 50% and number of organs involved were: 2 (72%), 3 (22%) and 4 (6%). RESULTS: After 3 cycles, partial (PR) and no change (NC) responses occurred in 15 pts (83.3%) and 3 pts (16.7%). The best overall response after 6 cycles, including complete (CR) and partial (PR) responses, occurred in 13 pts (72.2%) including 3 CRs and 10 PRs. Two patients with extensive liver metastases at the baseline had a complete disappearance after 6 cycles. No patients developed congestive heart failure (CHF). Grade 3/4 hematological toxicities included leukopenia in 18 pts (100%), febrile neutropenia in 6 pts (33%), leukopenia with infection in 2 pts (11%), leukopenia with fever in 1 pt (5.5%), and anemia in 6 pts (33.3%). Nonhematological toxicities grade 3/4 included alopecia (61%), asthenia (4.6%), nausea/vomiting (2.7%), pain (2.7%), stomatitis (2.7%), and diarrhoea (0.9%). Leukopenia was generally of short duration, occurred mainly during the first and second cycle, and did not require any dose reduction. There was one death due to progressive disease after six cycles of treatment. CONCLUSION: Taxotere--doxorubicin combination is very active in the first-line treatment of MBC, seems to be especially effective in patients with liver metastases, and is associated with a manageable toxicity profile.
