Analysis of clinicopathologic characteristics and prognosis of gastric cancer in patients <40 years.

An increase trend and a bad prognosis toward gastric cancer (GC) in individuals <40 years have been observed over the past few decades. GC in Young adult needs further evaluation to identify clear risk factors for early screening and better prognosis. A total of 126 young adult patients with gastric cancer (individuals <40 years) (YG) were collected in Liaocheng hospital in China from Jan 2003 to Dec 2019. The overall median follow-up was 96.5 months (rang 1-192 months). Survival was determined by the Kaplan-Meier method and the difference in survival among different subgroups were assessed using the log-lank test. Correlations between risk factors and overall survival were assessed by univariate and multivariate Cox proportional hazards regression analysis. Advanced stage cancer at onset and undifferentiated histologic tumor type were the prominent clinicopathological features of YG. The 5-year overall survival of the YG was 31.7%. The 5-year survival of the YG differed from tumor staging and treatment methods. The 5-year survival was 100% in stage I group, 58.8% in stage II group, 22.6% in stage III group, and 8.3% in stage IV group respectively. The 5-year survival was 52.1% in the curative resection group versus 3.8% in the non-curative resection group. Multivariate analysis displayed that tumor staging (P = .002) and treatment method (P = .034) were 2 independent prognostic predictors for survival. GC in young adult patients have unique clinicopathological features. Upper gastrointestinal endoscopy should regularly perform for young adult especially those symptomatic patients. Early diagnosis and then proceed to a successful curative resection are vital for a better prognosis.
