Relationship of age and survival after surgery with curative intent for gastric cancer in adults: A single center observational study

Abstract

Introduction: Gastric cancer is one of the diseases with the highest morbidity and mortality worldwide; however, early interventions can reduce mortality. This study aimed to determine the relationship between age and survival after surgery with curative intent for gastric cancer in patients treated at the SOLCA Cancer Institute, Cuenca, in 2012-2017.

Methods: The present analytical, retrospective study was carried out with the database of the SOLCA-Cuenca Cancer Institute. Data were presented in frequency and percentage tables. Chi-square (X2), Kaplan Meier analysis, and Cox regression were applied to relate the variables age and years of survival, being considered statistically significant when P<0.05.

Results: Of the 603 patients with gastric cancer registered during the evaluation period, 35.3% underwent surgery, achieving a follow-up of 45.1%. A total of 96 patients were included, 70.8% underwent surgery with curative intent. The sample was dominated by men (52.9%) and the age group of 70 to 79 (30.2%). The 5-year survival rate was 69.1%, with a median survival time of 7.24±0.49 years. Age was not significantly related to patient survival (X2=3.15; P=0.667).

Conclusion: there is a high 5-year survival rate in patients with gastric cancer who underwent surgery with curative intent, which was not associated with age.
