title: Is platinum-based chemotherapy with paclitaxel effective in optimally debulked patients with advanced ovarian cancer?
abstract: OBJECTIVE
  Suboptimally debulked patients with advanced ovarian cancer who are treated with a combination of cisplatin plus paclitaxel (TP therapy) have a better survival as compared to patients treated with a combination of cisplatin plus cyclophosphamide (CP therapy), but this advantage has not been demonstrated in optimally debulked patients. We performed a retrospective study to compare the effectiveness of TP therapy and CP therapy in optimally debulked patients.
  
  
  METHODS
  From 1991 to 1996, 87 consecutive patients with advanced ovarian cancer treated in the University Hospital Utrecht and the St. Antonius Hospital were included in the study. Overall survival (OS) of patients treated with TP or CP were compared. Multivariable Cox-regression analysis was used to calculate a hazard rate ratio (HRR) for OS.
  
  
  RESULTS
  In the study period, 51 patients were treated with CP, and 36 patients were treated with TP. In the 18 patients with a tumorrest >2cm, there was a clear, but not statistically significant benefit from TP. In 69 patients with a tumorrest <or=2cm, life expectancy was not increased in patients treated with TP as compared to patients treated with CP (HRR 0.9 (95% CI 0.4-1.9)).
  
  
  CONCLUSIONS
  We could not show that ovarian cancer patients with residual disease of <or=2cm who were treated with TP had better survival as compared to patients who were treated with CP. Taking into account the high costs of treatment with TP, a randomized trial comparing the effects of TP therapy and CP therapy in optimally debulked patients is warranted.
