Objective: To analyze the clinical and pathologic influencing factors of early recurrence in patents with gastric cancer after radical gastrectomy.
Methods: Clinicopathological data of 141 patients with recurrence after curative gastrectomy for gastric cancer from January 2001 to December 2004 were analyzed retrospectively. Risk factors correlated with tumor early recurrence and survival difference between early recurrence group (< 1 year, 82 cases) and control group (1 year after, 59 cases) were assessed.
Results: The 1- and 3-year survival rates of in early recurrence group and control group were 36.6%, 2.4% and 100%, 45.8%, respectively (P < 0.05). The median survival time after recurrence in the two groups was 3, 5 months, respectively (P < 0.05). Univariate analysis showed that the age, tumor Borrmann type, tumor site, invasive depth, lymph node metastasis, pTNM stage, metastatic lymph node ratio, surgical procedure and intraperitoneal hyperthermic perfusion chemotherapy (IHPC) were significant factors associated with early recurrence after curative gastrectomy for gastric cancer (P < 0.05). Lymph node metastasis, metastatic lymph node ratio and IHPC were independent factors associate with early recurrence after curative gastrectomy on multivariate analysis (P < 0.05).
Conclusions: The patients with early recurrence after the radical gastrectomy have a poorer survival compared with cases recur later. Lymph node metastasis, metastatic lymph node ratio and IHPC are independent factors associate with early recurrence after curative gastrectomy for gastric cancer.
