title: Phase II study of irinotecan and 5-fluorouracil/leucovorin in patients with primary refractory or relapsed advanced oesophageal and gastric carcinoma.
abstract: BACKGROUND
  The purpose of this study was to assess the efficacy and toxicity of irinotecan and 5-fluorouracil (5-FU) in primary refractory or relapsed locally advanced or metastatic oesophagogastric (O-G) carcinoma.
  
  
  METHODS
  Patients with documented progression on or within 3 months of chemotherapy were recruited between July 2000 and May 2002. Irinotecan (180 mg/m(2)) was given with 5-FU (400 mg/m(2) bolus) and leucovorin (folinic acid) (125 mg/m(2)) followed by 5-FU (1200 mg/m(2) infusion over 48 h) every 2 weeks. Response confirmed by computed tomography was assessed at 12 and 24 weeks.
  
  
  RESULTS
  Thirty-eight of 40 registered patients (95%) were assessable. Median follow-up was 9.3 months and median age was 59.0 years. Thirty-three patients (86.8%) had metastatic disease and 37 patients (97.4%) had previously received platinum-based chemotherapy. Overall response rate was 29% (95% confidence interval 15.4% to 45.9%) while an additional 34% had stable disease. Improvement in tumour-related symptoms included dysphagia 78.6%, reflux 60.0%, pain 54.5%, anorexia 64.3% and weight loss 72.7%. Grade 3/4 toxicities were anaemia 13.2%, neutropenia 26.4%, febrile neutropenia 5.2%, stomatitis 2.6%, nausea and vomiting 13.2% and diarrhoea 7.9%. Median failure-free survival was 3.7 months and median overall survival was 6.4 months.
  
  
  CONCLUSIONS
  5-FU/irinotecan is a valuable regimen for second-line treatment in 5-FU/platinum-resistant O-G carcinoma.
