Outcome of Gastric Cancer Surgery in Patients with Chronic Kidney Disease

Background: The influence of chronic kidney disease (CKD) on the outcome of gastric cancer surgery has rarely been reported.

Methods: Retrospectively collected clinicopathological data on patients who underwent elective gastrectomy between January 2007 and December 2014 were analyzed (n = 500). The patients were divided into 2 groups based on the preoperative estimated glomerular filtration rate (eGFR): a non-CKD group (eGFR ≥60 ml/min/1.73 m2, n = 392) and a CKD group (eGFR <60 ml/min/1.73 m2, n = 108). Short- and long-term results of the surgery were compared.

Results: There was no significant difference between the 2 groups in terms of the overall morbidity rate (p = 0.215), and in any kind of postoperative complication, including infectious and cardiovascular complications. Additionally, there was no significant difference in the morbidity rate irrespective of the type of gastrectomy and the extent of lymph node dissection. The 3-year relapse-free survival rates in the non-CKD and CKD groups were 92.1 and 92.0%, respectively, in stage I disease (p = 0.640), 81.4 and 73.7%, respectively, in stage II disease (p = 0.825), and 35.9 and 31.9%, respectively, in stage III disease (p = 0.784).

Conclusion: CKD did not affect the short- and long-term outcomes in patients after gastric cancer surgery.
