Background: The aim of this study was firstly to elucidate the prognosis of familial gastric cancer (FGC) in Chinese population. Methods: A total of 162 patients were recruited, including 81 patients with FGC and 81 patients with sporadic gastric cancer (SGC), who underwent gastrectomy between 1996 and 2007. Paraffin-embedded tumor specimens were obtained from tissue bank of Cancer Hospital, Fudan University. The expression of epidermal growth factor receptor (EGFR), P53, C-myc, and proliferating cell nuclear antigen (PCNA) were detected by immunohistochemical method. Results: There were significant differences in tumor size, vessel invasion, EGFR, and P53 expression between FGC and SGC patients. The 5-year survival rates were 48% and 57% in FGC and SGC patients, respectively (P = 0.033). Subgroup analysis showed that the 5-year survival rates were worse in FGC patients with nerve invasion, high PCNA expression, negative expression of EGFR, and positive expression of P53 than those in SGC group. Multivariate analysis showed that AJCC stage, tumor size, and nerve invasion were independent prognostic factors in all patients. Furthermore, AJCC stage and P53 expression dramatically affected the prognosis of FGC patients. Conclusions: The prognosis of FGC patients might be worse than those of SGC patients. AJCC stage and P53 expression are independent prognostic factors in FGC patients. J. Surg. Oncol. 2011;104:76-82. (C) 2011 Wiley-Liss, Inc.
