title: Cisplatin and etoposide regimen is superior to cyclophosphamide, epirubicin, and vincristine regimen in small-cell lung cancer: results from a randomized phase III trial with 5 years' follow-up.
abstract: OBJECTIVE
  To investigate whether chemotherapy with etoposide and cisplatin (EP) is superior to cyclophosphamide, epirubicin, and vincristine (CEV) in small-cell lung cancer (SCLC).
  
  
  METHODS
  A total of 436 eligible patients were randomized to chemotherapy with EP (n = 218) or CEV (n = 218). Patients were stratified according to extent of disease (limited disease [LD], n = 214; extensive disease [ED], n = 222). The EP group received five courses of etoposide 100 mg/m(2) intravenously (IV) and cisplatin 75 mg/m(2) IV on day 1, followed by oral etoposide 200 mg/m(2) daily on days 2 to 4. The CEV group received five courses of epirubicin 50 mg/m(2), cyclophosphamide 1,000 mg/m(2), and vincristine 2 mg, all IV on day 1. In addition, LD patients received thoracic radiotherapy concurrent with chemotherapy cycle 3, and those achieving complete remission during the treatment period received prophylactic cranial irradiation.
  
  
  RESULTS
  The treatment groups were well balanced with regard to age, sex, and prognostic factors such as weight loss, and performance status. The 2- and 5-year survival rates in the EP arm (14% and 5%, P =.0004) were significantly higher compared with those in the CEV arm (6% and 2%). Among LD patients, median survival time was 14.5 months versus 9.7 months in the EP and CEV arms, respectively (P =.001). The 2- and 5-year survival rates of 25% and 10% in the EP arm compared with 8% and 3% in the CEV arm (P =.0001). For ED patients, there was no significant survival difference between the treatment arms. Quality-of-life assessments revealed no major differences between the randomized groups.
  
  
  CONCLUSIONS
  EP is superior to CEV in LD-SCLC patients. In ED-SCLC patients, the benefits of EP and CEV chemotherapy seem equivalent, with similar survival time and quality of life.
