title: Second-line therapy with paclitaxel and carboplatin for recurrent disease following first-line therapy with paclitaxel and platinum in ovarian or peritoneal carcinoma.
abstract: OBJECTIVE
  The combination of paclitaxel and a platinum compound is the most active first-line regimen for advanced ovarian carcinoma. The current study was undertaken to evaluate this combination in the re-treatment of patients with ovarian or peritoneal carcinoma who had disease recurrence > or = 6 months following this combination.
  
  
  METHODS
  Twenty-five patients with recurrent ovarian or peritoneal carcinoma > or = 6 months after a complete clinical response with first-line paclitaxel and platinum chemotherapy were studied. Recurrent disease was documented by computed tomography (CT), elevated CA 125 level, or surgical findings. Second-line chemotherapy consisted of paclitaxel 135 mg/m2 as a 24 hour infusion and carboplatin at an area under the concentration-time curve (AUC) of 5 to 6 every 21 days. Response to therapy was classified as measurable or assessable.
  
  
  RESULTS
  The median time to recurrence after first-line therapy was 10 months (range, 6 to 30). Among 20 measurable and assessable patients, 14 (70%) demonstrated a complete clinical response and four (20%) a partial clinical response. The response rate with measurable disease was 91% and with assessable disease was 89%. The median progression-free interval for all patients was 9.0+ months (range, 2 to 15). The median progression-free interval for patients with measurable or assessable disease was 9.0+ months and for nonassessable disease was 7.0+ months. Fifteen patients (60%) have developed recurrence after secondary therapy at a median interval of 9.0 months (range, 2 to 15). Only two patients have died with a median survival after secondary therapy of 10.0+ months (range, 2.0 to 21.0+).
  
  
  CONCLUSIONS
  The use of this combination, in this sensitive population, has a high response rate and long progression-free interval. In a chemotherapy-sensitive population, the activity of alternative second-line agents must be interpreted with this perspective.
