Background: The aim of our study was to validate the value of combined preoperative prognostic nutritional index and body mass index in predicting overall survival (OS) and progression-free survival (PFS) in patients who underwent treatment of transarterial chemoembolization.
Methods: A single-centered retrospective study of 285 unresectable HCC patients who received treatment of transarterial chemoembolization from January 2013 to June 2015 was conducted. In our retrospective analysis, preoperative PNI and BMI data of patients were calculated and analyzed. The data of patient demographic, clinical, pathological and hematological characteristics were also systematically acquired and analyzed.
Results: Low PNI was correlated with cirrhosis, AFP ≥ 200 mg/L, Child-Pugh class B, ALT and AST ≥ 40 IU/L, TBIL≥ 21μmol/L, vascular invasion, tumor size ≥ 5 cm BCLC A/B and TNM III–IV stages (all p < 0.05). Likewise, low BMI was related to AFP ≥ 200 mg/L, Child-Pugh class B, AST ≥ 40IU/L, tumor size ≥ 5 cm, vascular invasion, BCLC C and TNM III–IV stages (all p < 0.05). In our multivariate analysis, AFP levels, tumor size, PNI and BMI were identified as independent predictive factors for OS and PFS of patients (all p < 0.05). Prominently, low PNI combined with low BMI adversely affected the overall survival and disease-free survival and the combination of PNI-BMI scores was proved to be the superior distinguished capacity compared with PNI or BMI alone because of higher area under the curve.
Conclusion: Preoperative PNI and BMI are independent predictors for prognosis in intermediate or advanced hepatocellular carcinoma patients after transarterial chemoembolization treatment. The PNI and BMI combination can promote the accuracy of prognostic prediction for patients with HCC compared with single score.
