299 EXAMINATION OF ALBUMIN/GLOBULIN RATIO IN ESOPHAGEAL CANCER

Abstract Albumin and globulin make up the majority of serum proteins and are strongly involved in inflammation. In recent years, reports on cancer and inflammation have been scattered, and there are reports indicating that the albumin / globulin ratio (A/G ratio) may be a predictor of prognosis in patients with cancer. Here, we examined the A/G ratio and clinicopathological factors in curative cases of esophageal cancer. Methods A retrospective study was conducted on 122 patients who underwent radical surgery for esophageal cancer in our department from January 2013 to December 2017. We analyzed the correlation between A/G ratio and blood biochemical test values, and the relationship between postoperative complications and prognosis. With respect to prognosis, the cut-off value was set to 1.6 from the ROC curve, and divided into a high-value group and a low-value group, and comparatively examined. Results There were 106 males and 16 females. The median age at surgery was 69 years. Neoadjuvant chemotherapy was performed in 65 patients. A negative correlation was found between the A/G ratio and inflammatory markers. On the other hand, a positive correlation was observed between the A/G ratio and the value of a marker for nutritional indicators. In the prognostic study, the low-value group had a significantly worse prognosis than the high-value group. The group with an A/G ratio of less than 1.6 after chemotherapy had a poor prognosis. The A/G ratio was lower in the group with pneumonia after surgery. Conclusion The A/G ratio reflects the preoperative inflammatory response and nutritional status, suggesting that it is a useful factor for predicting postoperative complications and prognosis in patients with curative esophageal cancer.
