In a phase II study, 66 patients with advanced breast cancer (median age 56 years; range, 28 to 75 years) were treated with paclitaxel (Taxol), 175 mg/m2 infused over 3 hours, and carboplatin (Paraplatin), dosed to attain an area under the concentration-time curve (AUC) of 6 mg x min/mL; treatment was repeated every 3 weeks. A total of 38 (58%) patients had received prior adjuvant chemotherapy, 21 with a regimen containing an anthracycline or mitoxantrone (Novantrone). As of May 1997, 295 cycles of paclitaxel-carboplatin have been administered, 248 (84%) at full dose. The relative dose intensity of paclitaxel is 0.9 (range, 0.5 to 1.2). Of the 66 patients, 8 (12%) have achieved a complete response and 27 (41%) a partial response, for a total response rate of 53%. Grade 3 to 4 toxicities have included anemia (5%), leukopenia (25%), thrombocytopenia (5%), nausea/vomiting (7%), myalgias/arthralgias (4%), allergic reaction, neurotoxicity, and infection (2% each). Alopecia has been universal. Median time to progression is 8.9 months; median survival has not yet been reached. We conclude that the combination of paclitaxel and carboplatin has significant activity in advanced breast cancer and can easily be administered on an outpatient basis with manageable toxicity.

Platinum-based chemotherapy regimens have been the mainstay of treatment for non-small-cell lung cancer because they improve survival. Although there is no standard platinum-based regimen, combination regimens with newer agents (e.g., gemcitabine [Gemzar], paclitaxel [Taxol], and vinorelbine [Navelbine]) are superior to platinum alone or in combination with older agents (e.g., etoposide). Four phase III clinical studies demonstrate the favorable activity and toxicity profile of gemcitabine in combination with cisplatin (Platinol) for the treatment of patients with stage IIIB or IV non-small-cell lung cancer. These studies show overall response rates of approximately 30% to 60% with gemcitabine regimens versus overall response rates of 11% with cisplatin alone, 22% with cisplatin plus etoposide, 25% with cisplatin plus vinorelbine, and 40% with cisplatin plus mitomycin and ifosfamide (Ifex). Median survival time with gemcitabine regimens ranged from 8.1 to 9.8 months. Thrombocytopenia and anemia are the principal toxicities with gemcitabine regimens. Because of the favorable results with gemcitabine regimens, this drug is being evaluated in combination with carboplatin (Paraplatin) in newly diagnosed patients with stage IIIB or IV disease and good performance status, or as single-agent therapy in patients with poor performance status.

The purpose was to conduct an integrated analysis of the cumulative hematologic toxicity of topotecan in patients with relapsed ovarian cancer and small cell lung cancer (SCLC). Data were pooled from eight phase II and phase III clinical studies performed in patients with relapsed stage III/IV ovarian cancer or extensive SCLC treated with topotecan at a dose of 1.5 mg/m(2) per day on days 1-5 of a 21-day course. Quantitative hematologic toxicities were assessed using the National Cancer Institute Common Toxicity Criteria. A total of 4,124 courses of therapy was administered to the 879 patients in the pooled population. Grade 4 neutropenia was experienced by 78% of patients. The lowest nadirs for neutrophils and platelets generally occurred after the first course of therapy, followed by improvement or stabilization in subsequent courses. Neutropenia was noncumulative. During the first course, significant risk factors were identified: renal impairment and advanced age (grade 3/4 thrombocytopenia and grade 4 neutropenia) and prior radiotherapy; performance status score > or =2; SCLC; and exposure to both cisplatin (Platinol; Bristol-Myers Squibb, Princeton, NJ, http://www.bms.com) and carboplatin (Paraplatin; Bristol-Myers Squibb) (grade 3/4 thrombocytopenia only). The most frequent interventions for hematologic toxicities were RBC transfusions, treatment delays, G-CSF support, and dose reductions. Analysis of neutrophil and platelet nadirs and dosing for each course of therapy showed no apparent evidence of cumulative neutropenia or thrombocytopenia. The risk of grade 3 or 4 anemia was higher during the first four courses of therapy and may need to be more aggressively managed with erythropoietin therapy.
