Premature mortality for patients after completely resected early adenocarcinoma of the esophagus or stomach

Abstract

Abstract Objective To establish the life expectancy burden of esophago‐gastric cancer by analyzing years of life lost (YLL) for a Western patient population after treatment of early esophageal (EAC) or early gastric (GAC) adenocarcinoma. Background For patients with early EAC or GAC, the short‐term prognosis after surgical resection is very good. Little data is available regarding long‐term prognosis when compared to the general population. Methods Two hundred and fourteen patients with pT1 EAC (n = 112) or GAC (n = 102) were included in the study. Patients with EAC underwent transthoracic en‐bloc esophagectomy; those with GAC had total or subtotal gastrectomy with D2‐lymphadenectomy. Surviving patients had a median follow‐up of approximately 14 years. YLL was calculated using average life expectancy data from Germany. Results Patients with EAC were younger (median age 61 years) than those with GAC (66 years) (p = 0.031). The male:female ratio was 10:1 for EAC and 3:2 for GAC (p < 0.001). Multivariate survival analysis showed the age of the patients ≥60 years and the existence of lymph node metastasis was associated with poor prognosis. The median YLL for all patients who died over follow‐up was 8.0 years. For patients under 60 years, it was approximately 20 years, and for older patients, approximately 5 years (p < 0.001) without difference in tumor stage between these age cohorts. YLL did not differ for GAC vs. EAC. Conclusion After surgical resection, the prognostic burden as measured by YLL is relevant for all patients with early esophageal and gastric adenocarcinomas and especially for younger patients. Reasons for YLL need further studies.
