Objective: Postoperative delirium (POD) is a common, but severe complication in elderly patients undergoing surgery for colorectal cancer, but the prevalence and potential risk factors for POD were not well established. Therefore, a meta-analysis was preformed to clarify the prevalence and risk factors of POD in patients undergoing surgery for colorectal cancer.

Methods: PubMed, Embase, and the Cochrane Library were systematically searched on August 2019. Studies were included if they reported the prevalence and risk factors of POD in patients undergoing colorectal cancer surgery. The guidelines for critically appraising studies of prevalence or incidence of a health problem were used to assess the quality of included studies. Pooled odds ratios (ORs) for individual risk factors were estimated using the Mantel-Haenszel methods in random effect model. Sensitive analyses based on different inclusion criteria were conducted to explore whether the current meta-analysis was enough credible and robust.

Results: Seventeen studies totaling 4472 patients undergoing colorectal cancer surgery were included. The pooled prevalence of POD is 14% (95% CI = 12-17%). Twelve significant risk factors were identified in pooled analysis including older age (OR = 1.10), sex (OR = 1.87), history of psychiatric disease (OR = 6.47), comorbidities (OR = 2.17), prognostic nutritional index (OR = 1.12), physical status (OR = 1.27), American Society of Anesthesiologists Score (ASA Scores) (OR = 1.65), history of alcohol abuse (OR = 2.23), postoperative pain management (OR = 1.91), perioperative blood transfusion (OR = 2.37), cognitive status (OR = 1.91), and lower serum level of albumin (OR = 0.58).

Conclusions: POD is a frequent complication in patients undergoing surgery with colorectal cancer. Several risk factors including history of psychiatric disease, transfusion, comorbidities, male gender, and old age were significant predictors for POD.

Prognostic value of pretreatment albumin/globulin ratio in digestive system cancers: A meta-analysis.

PLoS One 2018 4;13(1):e0189839. Epub 2018 Jan 4.

Department of General Surgery, The Fourth Affiliated Hospital of Nan Chang University, Nanchang, Jiangxi, China.

The albumin/globulin ratio (AGR) has been widely reported to be a potential predictor of prognosis in digestive system cancers (DSCs), but convincing conclusions have not been made. Therefore, herein, we performed a meta-analysis of relevant studies regarding this topic to evaluate the prognostic value of AGR in patients with DSCs. Three databases, including PubMed, EMBase, and Web of science, were searched comprehensively for eligible studies through September 8, 2017. The outcomes of interest included overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS). In our meta-analysis, pooled analysis of 13 studies with 9269 patients showed that a low AGR was significantly correlated with poor OS (HR = 1.94; 95% CI: 1.57-2.38; P <0.001). Five studies with 6538 participants involved DFS, and our pooled analysis of these studies also demonstrated that there was a significant association of a low AGR with worse DFS (HR = 1.49; 95% CI: 1.10 to 2.00; P < 0.001). In addition, only 2 studies referred to CSS, and we also detected a significant relationship between a low AGR and worse CSS from the results of our meta-analysis. In summary, a low pretreatment AGR was related to unfavorable survival in human digestive system cancers. A low pretreatment AGR may be a useful predictive prognostic biomarker in human digestive system cancers.
