dc.description.abstract | Background: Early-onset or familial gastric cancer (GC) is known to have clinicopathologic profiles different from those of sporadic GC. We aimed to compare DNA damage response marker expression between early-onset or familial GC and sporadic GC. Methods: GC samples were obtained from patients who underwent gastrectomy for GC at Seoul National University Hospital. Immunohistochemical analyses of various DNA damage response markers, including BRCA1, BRCA2, MRE11, RAD51C, and γH2AX, were performed using 54 early-onset GC, 59 familial GC, and 337 sporadic GC tissue microarray samples. Correlations between marker expression and clinicopathologic features were evaluated by univariate and multivariate analyses, and overall survival was analyzed. Results: The rate of γH2AX positivity was significantly higher (p < 0.001) in early-onset or familial GC than in sporadic GC. In contrast, the rates of MRE11 negativity and RAD51C negativity were significantly higher in sporadic GC than in early-onset or familial GC. BRCA1 negativity was associated with decreased overall survival in sporadic GC (p = 0.002), and MRE11 negativity was associated with decreased overall survival in sporadic GC (p = 0.012). Conclusion: Our results show significant differences in DNA damage response marker expression between early-onset or familial GC and sporadic GC. Creative Commons Attribution License | - |
