title: Efficacy and safety of the paclitaxel and carboplatin combination in patients with previously treated advanced ovarian carcinoma. A multicenter GINECO (Group d'Investigateurs Nationaux pour l'Etude des Cancers Ovariens) phase II study.
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.
  
  
  METHODS
  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.
  
  
  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.
  
  
  CONCLUSIONS
  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.
