The authors searched PubMed, Euro PMC, and Cochrane databases for studies evaluating preoperative hypoalbuminemia (plasma albumin < 3.5 mg/dL) as a predictor of postoperative outcomes in colorectal cancer surgery. The primary outcome was 30-day mortality; secondary outcomes included hospitalization time, thrombosis, surgical site infection, sepsis, and wound events. Studies were rated moderate to high quality via Newcastle-Ottawa scale, but heterogeneity was high (I² up to 99%) for several outcomes.

ABSTRACT

Background: In malnourished patients with colorectal cancer, hypoalbuminemia is common and was proposed to determine the postoperative outcome of colorectal surgery. Mounting articles published but have not been evaluated. We aim to assess the predictive value of preoperative hypoalbuminemia in patients undergoing colorectal surgery. Methods: We performed a literature search from PubMed, Euro PMC, and Cochrane with the terms serum albumin, hypoalbuminemia, prognosis, outcome, colorectal cancer, and neoplasm. We also hand-searched and included any relevant papers. Hypoalbuminemia is defined as plasma albumin level < 3.5 mg/dL. We restricted the included studies to English language and adults undergoing colectomy, laparotomy, laparoscopy, or abdominoperineal resection. Any types of articles were included, except an abstract-only publication and those that did not report the key exposure or outcome of interest. The key exposures were mortality, hospitalization time, and morbid conditions (thrombosis, surgical site infection, sepsis, and wound events). We pooled the odds ratio from each included literature as effect size. The Newcastle Ottawa scale and GRADE were used to determine the quality of each included study. Results: Hereof 7 observational studies (236,480 individuals) were included. Our meta-analysis found that preoperative hypoalbuminemia can predict the postoperative outcome in colorectal cancer patients. Individuals with hypoalbuminemia were not associated with 30-day mortality (risk ratio [RR] 2.05 [0.72, 5.86], P = .18, I 2 = 99%) but were associated with morbidity (RR 2.28 [1.78, 2.93], P < .00001, I 2 = 87.5%), surgical complication (RR 1.69 [1.34, 2.13], P < .00001, I 2 = 98%), and hospitalization (RR 2.21 [1.93, 2.52], P < .00001, I 2 = 0%). According to newcastle ottawa scale, the included studies are of moderate to sound quality. Conclusions: The current systematic review and meta-analysis showed that preoperative hypoalbuminemia was significantly associated with morbidity, length of stay, and surgical complication but not mortality.
