Pediatric gastric adenocarcinoma: A National Cancer Data Base review

Academic Article


  • Purpose: We sought to compare the presentation, management, and outcomes in gastric adenocarcinoma cancer for pediatric and adult patients. Methods: Using the 2004 to 2014 National Cancer Database (NCDB), patients ≤ 21 years (pediatric)were retrospectively compared to > 21 years (adult). Chi-squared tests were used to compare categorical variables, and Cox regression was used to estimate hazard ratios (HR)for survival differences. Results: Of the 129,024 gastric adenocarcinoma cases identified, 129 (0.10%)occurred in pediatric patients. Pediatric cases presented with more advanced disease, including poorly differentiated tumors (81% vs 65%, p = 0.006)and stage 4 disease (56% vs 41%, p = 0.002). Signet ring adenocarcinoma comprised 45% of cases in the pediatric group as compared to 20% of cases in the adults (P < 0.001). Similar proportions in both groups underwent surgery. However, near-total gastrectomy was more common in the pediatric group (16% vs 6%, p < 0.001). The proportions of patients with negative margins, nodal examination, and presence of positive nodes were similar. There was no overall survival difference between the two age groups (HR 0.92, 95% Confidence interval 0.73–1.15). Conclusion: While gastric adenocarcinoma in pediatric patients present with a more advanced stage and poorly differentiated tumors compared to adults, survival appears to be comparable. Type of study: Retrospective cohort study. Level of evidence: III
