[Gastrectomy in Patients Aged<85 Years Who Had Gastric Cancer-A Single-Institutional Experience].

Background: This study examined the treatment outcomes of gastrectomy in patients aged<85 years who had gastric cancer(GC).
Methods: The postoperative short- and long-term outcomes of 27 patients aged<85 years who underwent gastrectomy for GC at our institute were retrospectively investigated.
Results: The median age was 87 years(range: 85-94 years), and 17 patients(63%)had comorbidities. Total, distal, and proximal gastrectomies were performed for 12, 14, and 1 patient, respectively. Only 13 patients(48%)underwent standard lymph lymphadenectomy(LND), while R0, R1, and R2 were performed for 23, 2, and 2 patients, respectively. The overall, surgical, and non-surgical complication rates were 59%, 26%, and 44%, respectively, even though the incidence of GradeBⅢa complications was only 4%, and there was no mortality. The 1-, 2-, and 3-year overall survival rates(OSR)were 91.7%, 79.4%, and 63.2%, respectively. The 3-year OSRs of the patients who underwent R0, R1, and R2 were 76.2%, 35.4%, and 0%, respectively. The 3-year OSR was significantly higher in the patients who underwent the standard LND(100%)than in those who underwent limited LND(36.6%).
Conclusion: The standard LND and R0 might also be useful for patients aged<85 years who had GC, although care should be taken for the high incidence of complications.
