The majority of women diagnosed with epithelial ovarian cancer will have persistent or recurrent disease after initial treatment. We evaluated response and toxicity in women with advanced stage disease given salvage paclitaxel as a low-dose, weekly infusion. We performed a retrospective review of 22 women with advanced stage epithelial ovarian (19 women) or primary peritoneal carcinoma (3 women) who had received low-dose, weekly paclitaxel salvage therapy. All women had refractory, persistent, or recurrent disease following first-line treatment with paclitaxel and platin chemotherapy. Response and toxicity were assessed. Measurable disease present on physical or radiologic exam and serum carbohydrate antigen-125 levels were used to assess disease response. Overall response rate to low-dose, weekly paclitaxel salvage therapy was 50% (27% complete, 23% partial). Median progression-free interval (PFI) in responders was 27 weeks (range, 14-68 weeks). Stabilization of disease occurred in an additional 27% of patients with a median PFI of 22 weeks (range, 15-89 weeks). No difference in response was detected between the 7 women with platin-sensitive disease and the 15 women with platin-resistant disease(P=0.19). The median dose of paclitaxel was 80 mg/m 2 (range, 60-80 mg/m 2 ). During a total of 325 weeks of paclitaxel treatment (median per patient, 12 weeks; range, 6-49 weeks), 13 treatment delays occurred (hematologic indication, 9; nonhematologic indication, 4). No cases of grade 4 hematologic toxicity, sepsis, or worsening neuropathy were documented. Weekly paclitaxel infusion given as salvage therapy results in significant clinical response, even in women previously treated with paclitaxel. The regimen is well tolerated with no cases of grade 4 neutropenia or worsening neuropathy in our population.
