N2 - Background: Surgery is the best option for cure of localised gastric adenocarcinoma (GAC). When surgery is not possible due to comorbidities or patient choice, definitive chemoradiation is an option. We report on one of the largest cohorts of localised GAC patients who did not have surgery. Methods: We identified 71 patients with localised GAC who received chemo/chemoradiation therapy but did not have surgery. We assessed various end-points: overall survival (OS), relapse-free survival (RFS), and clinical complete response (cCR; negative post therapy biopsy and no evidence of cancer by imaging). Results: The median follow-up time was 1.8 years (range; 0.4–10.6). Most of the patients were men (64.8%), and the median age was 73 years (range; 30–96). Reason for not having surgery included comorbidities in 34 (47.9%), poor performance status 14 (19.7%), and patient refusal 23 (32.4%). Of all 71 patients, a complete restaging evaluation with endoscopy and imaging could be performed for 50, and 32 (45.1%) achieved a cCR. For the entire cohort, the median OS was 2.1 years (95% confidence interval [CI] 1.78–2.55). The estimated OS rates at 2 and 5 years were 54% and 18%, respectively. Female gender (HR 0.39, 95% CI 0.16–0.98, p = 0.045) and chemoradiation (HR 0.25, 95% CI 0.06–1.01; p = 0.05) were independently associated with longer OS in the multivariate analysis. Conclusion: Our data show that patients with localised GAC treated with chemotherapy and/or chemoradiation, who do not undergo surgery, have a 5-year OS rate of 18%.
