Abstract

BACKGROUND AND OBJECTIVES Many patients with relapsed metastatic breast cancer are pre-treated with taxanes and anthracyclines, which are usually given in the neoadjuvant/adjuvant setting or as first-line treatment for metastatic disease. The primary objective of this study was to determine the overall response rate for combination treatment with gemcitabine and cisplatin in patients with locally advanced or metastatic breast cancer who had relapsed after receiving one adjuvant/neoadjuvant or first-line metastatic chemotherapy regimen containing an anthracycline with/without a taxane. Secondary endpoints included duration of response, time to progression, one-year survival probability, and toxicity. DESIGN AND SETTING A single-arm, open-label, phase 2 study conducted at 17 investigative sites in Egypt. PATIENTS AND METHODS Treatment consisted of gemcitabine (1250 mg/m 2 ) on Days 1 and 8 and cisplatin (70 mg/m 2 ) on Day 1 of each 21-day cycle. Treatment continued until disease progression or a maximum of 6 cycles. RESULTS Of 144 patients all were evaluable for safety and 132 patients were evaluable for efficacy. The overall response rate was 33.3% and 45.5% of the patients with stable disease as their best response. The median time to progression was 5.1 months and the one-year survival probability was 73%. The most common grade 3/4 adverse events were nausea/vomiting (20.1%), neutropenia (19.4%), anemia (13.9%), asthenia (11.1%), diarrhea (9.7%), stomatitis (7.6%), leucopenia (7.6%), and thrombocytopenia (6.2%). Twelve (8.3%) patients had serious adverse events. CONCLUSIONS The results of this study indicate that gemcitabine and cisplatin were active and generally well tolerated in pretreated patients with locally advanced or metastatic breast cancer.
