BACKGROUND Hemoglobin and albumin are associated with the prognosis of gastric cancer(GC)patients. However, the prognostic value of the hemoglobin to albumin ratio(HAR) for the short-term survival of GC patients with D2 radical resection has not been studied.AIM To investigate the significance of the HAR in evaluating the short-term survival of GC patients after D2 radical resection and to construct a nomogram to predict the prognosis in GC patients after surgery, thus providing a reference for the development of postoperative individualized treatment and follow-up plans.METHODS Cox regression and Kaplan-Meier analysis was used for prognostic analysis.Logistic regression was used to analyze the relationships between HAR and the clinicopathological characteristics of the GC patients. A prognostic nomogram model for the short-term survival of GC patients was constructed by R software.RESULTS HAR was an independent risk factor for the short-term survival of GC patients.GC patients with a low HAR had a poor prognosis(P < 0.001). Low HAR was markedly related to high stage [odds ratio(OR) = 0.45 for Ⅱ vs Ⅰ;OR = 0.48 for Ⅲ vs Ⅰ], T classification(OR = 0.52 for T4 vs T1) and large tumor size(OR = 0.51 for ≥4 cm vs < 4 cm)(all P < 0.05). The nomogram model was based on HAR, age,CA19-9, CA125 and stage, and the C-index was 0.820.CONCLUSION Preoperative low HAR was associated with short-term survival in GC patients.The prognostic nomogram model can accurately predict the short-term survival of GC patients with D2 radical resection.
