Abstract
The purpose of this meta-analysis was to evaluate the impact of chronic kidney disease on short-term complications and long-term survival in patients with gastric cancer.
The PubMed, Embase, and Cochrane Library databases were searched from inception to May 18, 2021. The search strategy focused on two keywords: chronic kidney disease and gastric cancer. Pooled odds ratios, mean differences, and hazard ratios were analyzed. RevMan 5.3 was used for data analysis in this meta-analysis.
A total of seven studies including 3,346 patients were included in this meta-analysis. The chronic kidney disease group had a higher proportion of males and older patients, lower albumin levels, higher comorbidity rates, and higher N staging. The chronic kidney disease group had higher rates of overall postoperative complications (OR = 2.05, 95% CI = 1.38 to 3.05, P = 0.0004), more severe postoperative complications (OR = 2.06, 95% CI = 1.59 to 2.66, P < 0.00001), and higher rates of cardiovascular-related complications, anastomotic leakage, pneumonia, wound infections, pancreatic-related diseases and short-term death. Furthermore, the chronic kidney disease group had poorer overall survival than the nonchronic kidney disease group (HR = 2.89, 95% CI = 2.20 to 3.80, P < 0.00001).
Preexisting chronic kidney disease was associated with higher complications and poorer overall survival following gastrectomy in patients with gastric cancer.
