Abstract
An elevated serum albumin (ALB) and albumin/globulin ratio (AGR) have been reported to be associated with a favorable prognosis for several types of cancer. However, little is known about prognostic significance of globulin (GLB) in gastric cancer patients. The purpose of this study was to evaluate whether GLB, ALB, and AGR analysis could predict the prognosis of patients with gastric cancer. A retrospective cohort of 186 patients with gastric cancer followed by radical surgery was recruited between January 2007 and December 2010. Levels for preoperative GLB and ALB were obtained and used to calculate the AGR. Survival analysis was used to evaluate the predictive value of GLB, ALB, and AGR. X-tile program determined 37.6, 33.4, and 1.33 as the optimal cutoff value for ALB, GLB, and AGR in terms of survival. Univariate analysis revealed that low GLB levels were significantly associated with favorable survival (P = 0.045). Conversely, low ALB levels were associated with a significantly worse survival (P = 0.000). In conclusion, low preoperative GLB level may serve as a valuable marker to predict the prognosis of gastric cancer patients.
