Gastric adenocarcinoma (GAC) is an extremely rare cancer in children with very limited information on the clinical presentation and outcome. We report five pediatric patients with GAC-treated between 1990 and 2008 at our institution. Median age at diagnosis was 17 years (range: 8-17). Our case series suggests that pediatric GAC patients present with diffuse metastatic disease (four patients) and with patterns of spread similar to adult GAC. Initial chemotherapy was mainly platinum-based. Median time to progression was 4 months. The only long-term survivor was a patient with localized disease who had complete surgical removal of primary tumor.
