title: [Clinical evaluation of DLF, CLF and DFM regimens based on platinum compound plus 5-fluorouracil for treatment of advanced esophageal carcinoma].
abstract: OBJECTIVE
  Combination chemotherapy with 5-fluorouracil (5-FU) and cisplatin is regarded as the standard regimen for advanced esophageal carcinoma. This study was to evaluate the efficacy and safety of DLF, CLF and DFM regimens, based on platinum compound plus 5-fluorouracil in the treatment of advanced esophageal carcinoma, and to further explore prognostic factors of advanced esophageal carcinoma.
  
  
  METHODS
  From October 1999 to December 2004, 98 patients with advanced esophageal carcinoma were enrolled in the study. They were non-randomly assigned to receive a 2-hour infusion of folinic acid 200 mg/m(2), followed by a 5-FU bolus 400 mg/m(2) and 48-hour infusion of 5-FU 3,000 mg/m(2) every 3 weeks, combined with cisplatin 80 mg/m(2) (DLF, n=48) or with carboplatin AUC=5 on day 1 (CLF, n=32), or with cisplatin 80 mg/m(2), 5-fluorouracil bolus 400 mg/m(2) on day 1-5 plus pingyangmycin 5 mg/m(2) on day 1, 3, 5 (DFM, n=18). Survival analysis and prognostic factors were evaluated by Kaplan-Meier method and Cox regression analysis.
  
  
  RESULTS
  All 98 patients were assessable for response and toxicity. There were 13 complete response, 36 partial response, 45 no changes and 4 progressive disease with a total response rate of 46.86%. The response rates of DLF, CLF and DFM regimens were 60.42%,46.86% and 27.78%, respectively (DLF vs DFM, P=0.027). The major side effects were nausea-vomiting, alopecia, bone marrow suppression and mucositis, and the others were uncommon. All side effects were tolerable and mild except for nausea-vomiting. Nausea-vomiting was mildest in CLF among the three regimens. After a median follow-up of 9 months, the overall median survival was 9 months (95% CI, 6.67 to 11.33 months), the median survival of the patients treated with DLF, CLF or DFM regimen was 10, 9 and 7 months, respectively (P=0.7402). Better prognosis was correlated with good conditions of patients before chemotherapy (KPS> or =80, P=0.000) and metastasis to lymph node, parenchyma or bone in stead of visceral organs (P=0.026). There was no correlation between the prognosis and age, sex, types of pathology and the regimen of therapy.
  
  
  CONCLUSIONS
  The DLF regimen is tolerable and more effective, thus could be recommended as a front-line standard treatment for advanced esophageal carcinoma. The CLF regimen is more suitable for feeble and older patients since it has the mildest side effects. The prognostic factors of advanced esophageal carcinoma include conditions before chemotherapy and the location of metastasis.
