Doxorubicin and paclitaxel both display strong antitumor activity in the treatment of breast cancer. The optimal schedule of this combination, however, remains undefined. In this phase I and pharmacologic study, we administered weekly 12 mg/m2 doxorubicin as a bolus infusion immediately followed by a 1 h 80 mg/m2 paclitaxel infusion to patients with metastatic breast cancer. A total of 119 weekly courses were delivered to seven patients. Grade IV neutropenia was observed in two patients at the first dose level, thus already defining the maximum tolerated dose. Pronounced non-hematologic toxicities were mild neuropathy (grade I: 39%) and stomatitis (grade I: 19%, grade II: 8%). No signs of cardiac toxicity were observed with this dose schedule. Three partial responses were achieved in this group of heavily pretreated patients. The pharmacokinetics of paclitaxel, doxorubicin and Cremophor EL with this schedule were analyzed. Overall, the schedule was well tolerated and combined with its preliminary response rate justifies further evaluation in phase II studies.

Topotecan does not convincingly alter the grim prognosis of ovarian cancer in failure or relapse after treatment with platinum salts. The only comparative trial has not yet been published; available results suggest that 20% of women had at least a partial response on topotecan, compared to 14% on paclitaxel (no statistically significant difference). The place of paclitaxel in the treatment of ovarian cancer also remains to be determined, especially in combination with other drugs. Like paclitaxel, topotecan has marked haematological and gastrointestinal toxicity: nausea, vomiting, diarrhoea and stomatitis. Topotecan solution does not contain the solvent Cremophor EL degrees , contrary to paclitaxel solution. It does not therefore require preliminary steroid administration, and does not prohibit the use of PVC-based infusion devices.
