title: Phase II clinical trial of advanced and metastatic gastric cancer based on continuous infusion of 5-fluorouracil combined with epirubicin and oxaliplatin.
abstract: OBJECTIVE
  To evaluate the efficacy and tolerability of systematic treatment of unresectable advanced or metastatic gastric cancer (A/MGC) based on EOF5 regimen (the combination of epirubicin, oxaliplatin and 5-day continuous infusion of 5-fluorouracil).
  
  
  METHODS
  Twenty-six patients (18 males, 8 females; age range, 35-72 years) with histologically confirmed metastatic (n = 23) or unresectable advanced (n = 3) gastric adenocarcinoma with (n = 6) or without previous chemotherapy (n = 20) were consented to receive EOF5 (epirubicin 50 mg/m(2) and oxaliplatin 130 mg/m(2) on day 1, followed by continuous infusion of 5-fluorouracil 375-425 mg/m(2) day(-1) on day 1-5), and the treatment cycle was repeated every 3 weeks. Responses to treatment and toxicity were evaluated every 2 cycles.
  
  
  RESULTS
  In the first-line treatment group of 20 patients, complete (CR) and partial (PR) remission were observed in two (10%) and six (30%) patients, respectively with an overall response rate of 40%). Eleven (55%) patients showed stable (SD) and one (5%) progressive disease (PD). One-year survival rate, time to progression (TTP) and median overall survival (OS) were 45%, 9.7 and 12.5 months, respectively. In the second-line treatment group of six patients, the numbers of CR, PR, SD and PD were 0, 1, 4 and 1, respectively. Symptomatic response rates were 88.2, 76.9, 89.5, and 88.9% for abdominal pain, distention, anorexia and weight loss. The mean Karnofsky performance status score was increased (P < 0.001) and maintained after two and four cycles treatment. The major adverse events were nausea/vomiting, oral mucositis, peripheral neuropathy, phlebitis, constipation and myelosuppression. CTC grade 3 or 4 hematologic toxicities included leucopenia (7.7%), neutropenia (15.4%), thrombocytopenia (19.2%), and anemia (3.8%). No treatment-related deaths were recorded.
  
  
  CONCLUSIONS
  EOF5 regimen shows good efficacy and an acceptable safety profile in A/MGC patients, and would be a suitable alternative regimen for this indication.
