Abstract

BACKGROUND:

Platinum compounds are the most active drugs in ovarian cancer treatment; cisplatin and carboplatin demonstrated similar efficacies but different toxicity profiles. Paclitaxel combined with cisplatin as first-line treatment improved overall survival when compared to a cisplatin-cyclophosphamide combination, but generated higher rates of neutropenia, febrile neutropenia and neurotoxicity. The paclitaxel-carboplatin combination may be better tolerated than cisplatin-paclitaxel.

DESIGN:

The objective of the present study was to assess the efficacy and safety of the combination of paclitaxel and carboplatin in previously treated advanced ovarian cancer patients.

PATIENTS AND METHODS:

During or after platinum-based chemotherapy, 73 patients with progressive advanced epithelial ovarian carcinoma were enrolled to receive every four weeks a three-hour infusion of paclitaxel 175 mg/m2 followed by a 30-minute carboplatin infusion. The carboplatin dose was calculated to obtain the recommended area concentration-versus-time under the curve of 5 mg x ml-1 x min.

RESULTS:

Toxicity and response could be evaluated for 72 and 62 patients, respectively. Eleven complete and 15 partial responses gave an overall response rate of 42% (95% CI: 30%-54%). Response rates for platinum-refractory patients and those with early (> or = 3 and < 12 months) and late (> 12 months) relapses were 24%, 33% and 70%, respectively. The respective median response duration, the median progression-free survival and median overall survival were 8, 6 and 14 months. Myelosuppression was the most frequent and severe toxicity. Grade 3 and 4 neutropenia occurred, respectively in 30% and 23% of the cycles; 6% of the cycles benefited from medullary growth factors. Only one episode of febrile neutropenia was observed. Grade 3 and 4 thrombocytopenia occurred, respectively during 3% and 1% of the cycles. Alopecia was frequent. Transient peripheral neuropathy developed in 47% of patients but was severe in only one patient. One early death was attributed to progressive disease and possibly to therapy.

CONCLUSION:

This combined paclitaxel-carboplatin therapy is effective and can be safely administered to ovarian cancer patients who relapse after one or two regimens of platinum-based chemotherapy.
