Survival and prognosis of young adults with gastric cancer

OBJECTIVES: Survival data for young adults (YA) with gastric cancer is conflicting and scarce in Brazil. The aim of this study was to compare the clinicopathological factors and survival rates of younger and older patients with gastric cancer. METHODS: Hospital registries for 294 gastric cancer patients from a reference cancer hospital in São Paulo, Brazil, were consulted for the retrieval of clinicopathological information and follow-up time. Patients were placed into the following groups: YA (≤40 years; N=71), older adult (OA: 41 to 65 years; N=129) and elderly (E: ≥66 years; N=94). Differences were assessed through Pearson’s χ2 test, Kaplan-Meier analysis, Log rank test and Cox regression. RESULTS: More YA were diagnosed with advanced disease (clinical stage III/IV: 86.7% YA, 69.9% OA, and 67% E); however, fewer E patients underwent surgery (64.3% YA, 72.7% OA, and 52.4% E). The median overall survival among all patients was 16 months, and the overall survival rate was not significantly different among the age groups (p=0.129). There were no significant differences in the disease-free survival rate. Metastatic disease at diagnosis (HR=4.84; p<0.01) was associated with an increased hazard of death for YA. CONCLUSION: Overall survival was similar among age groups. Metastatic disease at diagnosis was the only factor associated with a poorer prognosis in YA. These results suggest that younger patients deserve special attention regarding the detection of early stage disease.
