Abstract
BACKGROUND: The relationship between perioperative allogeneic blood transfusions (PABTs) and prognosis in patients with gastric cancer remains controversial. METHODS: Six hundred five consecutive patients with gastric cancer who underwent curative gastrectomy from a single center were enrolled in this retrospective study. Clinical and pathologic variables were prospectively collected. The effect of PABT on the long-term survival of patients with gastric cancer after curative gastrectomy was evaluated by univariate and multivariate analyses. RESULTS: The overall 5-year survival rate was 65.0%. On univariate analyses, PABT had a statistically significant negative impact on 3-year and 5-year survival rates (66.3% vs 80.5% [P = .005] and 38.7% vs 76.4% [P < .001], respectively). However, multivariate analyses revealed that duration of operation (P = .009), tumor size (P = .001), and tumor stage (P < .001), instead of PABT, were independent prognostic factors. CONCLUSIONS: Our study indicates that PABT is not an independent prognostic factor for long-term survival in patients with gastric cancer after curative gastrectomy. Crown
