  •   Objective  To investigate the impact of portal vein tumor thrombus (PVTT) classification on rebleeding in hepatocellular carcinoma (HCC) patients with different PVTT subtypes and esophagogastric variceal bleeding (EGVB), and to provide a reference for formulating rational treatment regimens for such patients.  Methods  A retrospective study was performed for 130 patients with HCC and PVTT who were treated due to EGVB in Beijing Ditan Hospital, Capital Medical University, from July 2020 to January 2025, and according to whether endoscopic treatment was performed, the patients were divided into endoscopic treatment group with 97 patients and conservative treatment group with 33 patients. Demographic and clinical data were collected from all patients, and the two groups were compared in terms of hemostasis success rate and rebleeding rate. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to estimate the cumulative incidence rate of rebleeding in patients with different subtypes of PVTT. Propensity score matching (PSM) was performed for the endoscopic treatment group and the conservative treatment group to balance the baseline data of the two groups. The Cox proportional hazards model was used to perform univariate and multivariate analyses and identify independent risk factors for rebleeding.  Results  The endoscopic treatment group had a significantly lower cumulative rebleeding rate within 6 months than the conservative treatment group (35.1% vs 57.6%, hazard ratio [HR]=0.480, 95% confidence interval [CI]: 0.272—0.851, P=0.019). The PVTT Ⅲ—Ⅳ group had a significantly higher cumulative rebleeding rate within 6 months than the PVTT Ⅱ group (52.2% vs 37.5%, HR=1.744, 95%CI: 1.008 — 3.018, P=0.022). After PSM, there was no significant difference in rebleeding rate between the endoscopic treatment group and the conservative treatment group (38.1% vs 14.3%,HR=1.500,95%CI:0.125 — 2.002, P=0.588), while the PVTT Ⅲ—Ⅳ group had a significantly higher cumulative rebleeding rate than the PVTT Ⅱ group (58.8% vs 12.5%,HR=1.561,95%CI:1.195 — 12.499,P=0.033). The multivariate Cox regression analysis showed that PVTT subtype (HR=1.412, 95%CI: 0.998 — 1.997, P=0.049), platelet count (HR=1.006, 95%CI: 1.001 — 1.010, P=0.021), C-reactive protein (HR=1.011, 95%CI: 1.001 — 1.021, P=0.026), and ascites (HR=1.803, 95%CI: 1.059 — 3.068, P=0.030) were independent risk factors for rebleeding.  Conclusion  For HCC patients with PVTT and EGVB, endoscopic treatment can successfully achieve hemostasis, while it fails to significantly reduce rebleeding rates. PVTT classification can affect the risk of rebleeding, and patients with PVTT types Ⅲ—Ⅳ have a relatively high rebleeding rate.
