Background
Oral fluoropyrimidines are widely used as standard treatment for gastric cancer, but peritoneal disseminated gastric cancer patients are often ineligible for chemotherapy using oral anticancer agents because of inadequate oral intake. The purpose of this study was to evaluate the treatment outcome and identify the prognostic factors in gastric cancer patients with inadequate oral intake resulting from peritoneal dissemination.
Methods
Seventy-nine patients with peritoneal disseminated gastric cancer receiving systemic chemotherapy as the first-line treatment option at our hospital between April 1999 and December 2006, and who were administered intravenous drip infusion because of inadequate oral intake, were retrospectively analyzed.
Results
All patients received 5-fluorouracil (5-FU)-based chemotherapy. Of the 79 treated patients, 71 had ascites as peritoneal dissemination and the remaining 8 had only gastrointestinal stenosis without ascites. Eleven (15%) patients showed an improvement in ascites. Proportion of oral intake improvement was 33%. Median time to progression and overall survival time was 1.7 months [95% confidence interval (CI), 0.9–2.4 months] and 3.3 months (95% CI, 2.1–4.5 months), respectively. Four independent poor prognostic factors were identified in multivariate analysis: serum albumin < 3.0 g/dl [hazard ratio (HR) 1.69, P = 0.03], performance status ≥ 3 (HR 1.78, P = 0.05), massive ascites (HR 1.79, P = 0.04), and serum C-reactive protein ≥ 2.0 mg/dl (HR 2.03, P < 0.01).
Conclusion
The efficacy of 5-FU-based chemotherapy for peritoneal disseminated gastric cancer patients with inadequate oral intake was unsatisfactory.
