Preoperative serum glutathione reductase activity and alpha-fetoprotein level are associated with early postoperative recurrence of hepatocellular carcinoma

Abstract

Objectives The aim of this study is to investigate the correlation between preoperative serum glutathione reductase (GR) activity, alpha-fetoprotein (AFP) level, and early postoperative recurrence in patients diagnosed with hepatocellular carcinoma (HCC). Methods The data of 91 patients with HCC who underwent hepatectomy at Jinhua Hospital from January 2020 to December 2021 were retrospectively analyzed. A comparison of clinical characteristics between Non-Recurrent group and Recurrence group was conducted, and the association between GR activity, AFP levels, and early postoperative recurrence in HCC was investigated. Results Recurrence group (n=50) had a significantly higher AFP levels (median: 226.7 vs. 99.7 μg/L, p<0.001) and significantly lower GR activity (median: 55.0 vs. 68.0 U/L, p<0.0001) compared with Non-Recurrent group (n=41). The GR activity was negatively correlated with the AFP level (r=−0.4275, p<0.01). Low GR activity (OR=0.948; 95 % CI: 0.910–0.988; p=0.011) and high AFP levels (OR=1.003; 95 % CI: 1.000–1.006; p=0.036) independently contribute to an increased risk of early postoperative recurrence in HCC patients. The area under receiver operating characteristic curve of GR activity and AFP level for predicting early postoperative recurrence of HCC was 0.790 and 0.708, respectively. Patients with GR >60U/L had a higher early postoperative non-recurrence rate than patients with GR ≤60U/L (71.4 % [30/42] vs. 22.4 % [11/49]; HR=4.026; 95 % CI: 2.254–7.188; p<0.01); Patients with AFP ≤100 μg/L had a higher early postoperative non-recurrence rate than patients with AFP >100 μg/L (65.6 % [21/32] vs. 33.9 % [20/59]; HR=2.490; 95 % CI: 1.397–4.438; p<0.01). Conclusions The preoperative serum GR activity and AFP level hold significant predictive value for early postoperative recurrence in HCC patients.
