Gastric Cancer Surgery – A Balance of Risk and Radicality

INTRODUCTION: The aim of this study was to determine whether tailoring the extent of resection would allow radical gastric cancer surgery to be performed safely in a UK population. PATIENTS AND METHODS: A total of 180 consecutive patients (median age 70 years; male:female ratio 2:1) undergoing resection for gastric adenocarcinoma with curative intent were studied. Extent of lymphadenectomy was based upon pre-operative and intra-operative staging, and balanced against the patient's age and fitness. RESULTS: In the study group, 83 patients underwent subtotal or distal partial gastrectomy and 97 patients underwent total or proximal partial gastrectomy. Operative procedures were: D1 lymphadenectomy (n = 62); modified (spleen and pancreas pre-serving) D2 lymphadenectomy (n = 73); D2 lymphadenectomy (n = 42); and extended resection (n = 3). TNM classification was: stage 1 (n = 45); stage 2 (n = 37); stage 3 (n = 61); and stage 4 (n = 37). Of the patients, 48 developed postoperative complications including 17 patients with a major surgical complication. The in-hospital mortality was 1.7% (3 of 180). Predicted mortality according to POSSUM and P-POSSUM was 21.4% and 7.8%, respectively. Disease-specific 5-year survival according to stage was 85.4%, 64.2%, 33.3%, and 6.9%. CONCLUSIONS: By tailoring the extent of resection and balancing risk and radicality, gastric cancer surgery can be performed with low mortality in Western patients.
