- Abstract
Simple Summary: Discovering hypervascular incidentalomas (HVIs) during intra-arterial therapies (IATs) for hepatocellular carcinoma (HCC) is a common condition, but guidelines lack precise management suggestions. This study examines whether to include HVIs in IAT for HCC patients awaiting liver transplantation. A retrospective study analyzed liver-transplanted HCC patients who received TACE or TARE before LT from 2014 to 2018. The study compared HCC detection rates between pre-interventional imaging and per-interventional CBCT and investigated correlations between HVIs and poor prognosis criteria. Results showed higher nodule detection with CBCT and no significant correlations between HVIs and poor prognosis criteria, tumor recurrence, or mortality. Kaplan–Meier analysis found no significant impact of HVIs on recurrence-free, recurrence-related, or overall survival. These data may indicate that the treatment plan during IAT should not be impacted or modified in response to HVI detection in patients awaiting LT. Background: Current guidelines do not indicate any comprehensive management of hepatic hypervascular incidentalomas (HVIs) discovered in hepatocellular carcinoma (HCC) patients during intra-arterial therapies (IATs). This study aims to evaluate the prognostic value of HVIs detected on per-interventional cone beam computed tomography (CBCT) during IAT for HCC in patients waiting for liver transplantation (LT). Material and methods: In this retrospective single-institutional study, all liver-transplanted HCC patients between January 2014 and December 2018 who received transarterial chemoembolization (TACE) or radioembolization (TARE) before LT were included. The number of ≥10 mm HCCs diagnosed on contrast-enhanced pre-interventional imaging (PII) was compared with that detected on per-interventional CBCT with a nonparametric Wilcoxon test. The correlation between the presence of an HVI and histopathological criteria associated with poor prognosis (HPP) on liver explants was investigated using the chi-square test. Tumor recurrence (TR) and TR-related mortality were investigated using the chi-square test. Recurrence-free survival (RFS), TR-related survival (TRRS), and overall survival (OS) were assessed according to the presence of HVI using Kaplan–Meier analysis. Results: Among 63 included patients (average age: 59 ± 7 years, H/F = 50/13), 36 presented HVIs on per-interventional CBCT. The overall nodule detection rate of per-interventional CBCT was superior to that of PII (median at 3 [Q1:2, Q3:5] vs. 2 [Q1:1, Q3:3], respectively, p < 0.001). No significant correlation was shown between the presence of HVI and HPP (p = 0.34), TR (p = 0.095), and TR-related mortality (0.22). Kaplan–Meier analysis did not show a significant impact of the presence of HVI on RFS (p = 0.07), TRRS (0.48), or OS (p = 0.14). Conclusions: These results may indicate that the treatment plan during IAT should not be impacted or modified in response to HVI detection.
