Abstract:
PURPOSE:To investigate the clinicopathological features and survival outcomes between young and old patients with gastric cancer (GC), and further determine the role of young age in the prognosis of GC. METHODS:Patients with stage I-III gastric adenocarcinomas undergoing curative surgery were enrolled, divided into young (aged 18-49 years, YG), middle-aged (50-59 years, MG), and old (≥ 60 years, OG) groups. Exclusion criteria were neoadjuvant therapy and history of malignant tumors. Clinicopathological features, overall survival (OS), disease-free survival (DFS), and recurrence patterns were compared among three groups. RESULTS:1131 patients were finally included, with 270, 314, and 547 cases in the YG, MG, and OG, respectively. Compared to others, YG had higher proportion of female, middle-third gastric cancer, poor differentiation, N3b stage, and adjuvant chemotherapy. YG demonstrated poorer 5-year OS than MG (62.4% vs. 70.8%, P = 0.019), but better than OG (62.4% vs. 58.7%, P = 0.031). YG also suffered inferior 5-year DFS (75.2% vs. 82.8%, P = 0.040) compared with MG, and higher incidence of peritoneal recurrence than MG (15.1% vs. 5.2%, P < 0.001) and OG (15.1% vs. 4.1%, P < 0.001). Multivariate analysis identified young age as the independent prognostic factor for OS [hazard ratio (HR) = 1.347, 95% CI 1.018-1.781, P = 0.037], DFS (HR = 1.601, 95% CI 1.079-2.376, P = 0.019), and peritoneal recurrence (HR = 2.936, 95% CI 1.505-5.726, P = 0.002). CONCLUSIONS:Young GC patients demonstrated aggressive features with poor prognosis and enhanced management may be warranted for this subgroup.
