Geriatric nutritional risk index as a prognostic factor in patients with hepatocellular carcinoma following transarterial chemoembolization: A retrospective study.

The geriatric nutritional risk index (GNRI) has been shown to be associated with the prognosis of cancer patients except for hepatocellular carcinoma (HCC) patients after transarterial chemoembolization (TACE). Our aim is to examine the association between the GNRI and long-term prognosis in patients with HCC who underwent TACE. Patients with HCC who underwent TACE were enrolled. The relationship between the patient characteristics and GNRI were compared, and the independent prognostic factors were investigated. Nomogram performance was assessed via the concordance index (C-index) and calibration plots. Decision curve analysis (DCA) was performed to evaluate the net benefit of the nomogram. A total of 235 patients met the inclusion criteria. Compared with the parameters of the high GNRI group, low GNRI was significantly associated with hypertension, ascites, body mass index, tumor size, anemia, Child-Turcotte-Pugh class. The univariate analysis demonstrated that overall survival (OS) was inferior when GNRI < 98, tumor size ≥ 5cm, vascular invasion, alpha-fetoprotein level ≥ 400, Barcelona clinical liver cancer stage B to C and TACE times < 3. The multivariate analysis revealed that GNRI < 98, tumor size ≥ 5cm, tumor number ≥ 2, alpha-fetoprotein level ≥ 400 and TACE times < 3 were independent predictors of a poor OS. In the validation step, OS was shown to be well calibrated (C-index = 0.724), and a satisfactory clinical utility was proven by DCA. Low GNRI score was associated with a shorter OS in patients undergoing TACE.
