title: A retrospective study of second-line chemotherapy for unresectable or recurrent squamous cell carcinoma of the esophagus refractory to chemotherapy with 5-fluorouracil plus platinum.
abstract: BACKGROUND
  In Japan, chemotherapeutic agents that have been approved for the treatment of esophageal cancer include cisplatin, nedaplatin, 5-fluorouracil, vindesine, and docetaxel. We retrospectively investigated the efficacy and toxicity of a combination of nedaplatin plus vindesine, or docetaxel alone, for patients with unresectable or recurrent squamous cell carcinoma of the esophagus refractory to prior chemotherapy with 5-fluorouracil plus platinum.
  
  
  METHODS
  Nedaplatin was administered at 90 mg/m(2) intravenously on day 1, and vindesine was administered at 3 mg/m(2) intravenously on days 1 and 8 every 28 days. Docetaxel 60 mg/m(2) or 70 mg/m(2) was administered intravenously every 21 days. We analyzed the response rate, overall survival time, progression-free survival time, and toxicity in 24 patients treated with nedaplatin plus vindesine and 28 patients treated with docetaxel.
  
  
  RESULTS
  In patients treated with nedaplatin plus vindesine, the response rate of the 13 patients with measurable lesions was 8% (1/13), the median progression-free survival time was 1.8 months, and the median survival time was 5.5 months. In patients treated with docetaxel, the response rate of the 17 patients with measurable lesions was 18% (3/17), the median progression-free survival time was 2.1 months, and the median survival time was 5.1 months. The most frequent toxicity was neutropenia (grade 4; 13% in the group with nedaplatin plus vindesine and 50% in the docetaxel group), and febrile neutropenia (grade 3; 4% and 18%, respectively).
  
  
  CONCLUSIONS
  The efficacy of the two regimens for unresectable or recurrent squamous cell carcinoma of the esophagus refractory to chemotherapy with 5-fluorouracil plus platinum was unsatisfactory. New, more effective therapies are needed.
