Evaluation of transarterial chemoembolization refractoriness in patients with hepatocellular carcinoma.

ABSTRACT: BACKGROUND & AIM:In clinical practice, transarterial chemoembolization (TACE) has been widely used for the treatment of hepatocellular carcinoma (HCC) beyond as well as within guideline recommendations. Here we aimed to verify whether two consecutive non-responses could be an optimal criterion for creating a rule to stop TACE being performed on these patients. METHODS:This study evaluated 200 patients with HCC beyond the Milan criteria, initially treated with TACE. TACE response was determined using the mRECIST criteria via dynamic CT or MRI. Median follow-up duration was 23.9 months. RESULTS:Within the 200 patients analyzed, 183 (91.5%) were male, with a total median age of 59.8 years. The mean size of the largest tumor was 6.8 cm, with 80 (40.0%) patients with ?4 tumors. After the first TACE procedure, complete response, partial response, stable disease, or progressive disease were observed in 48 (24.0%), 87 (43.5%), 59 (29.5%) and 6 (3.0%) of patients, respectively. 45 (22.5%) patients showed no objective response (OR) following two consecutive TACE sessions. Of these, 28 received a subsequent TACE, with a 10.7% OR rate. Patients without OR showed poorer survival when compared to patients who achieved OR after repeated TACE. Multivariable analysis showed that size of the largest tumor >5cm and high alpha-fetoprotein of >200 ng/mL were significant factors associated with failure of OR to two consecutive TACE sessions. CONCLUSION:Patients showing no OR to two consecutive TACE sessions will present a poor OR to subsequent TACE procedures. Early transition to systemic therapy may be advocated in such cases.

Project description:BACKGROUND:For patients with hepatocellular carcinoma (HCC), the definition of refractoriness to transarterial chemoembolization (TACE), which might make them a candidate for systemic therapy, is still controversial. We aimed to derive and validate a tumor marker-based algorithm to define the refractoriness to TACE in patients with intermediate-stage HCC. METHODS:This multi-cohort study was comprised of patients who underwent TACE for treatment-naïve intermediate-stage HCC. We derived a prediction model for overall survival (OS) using the pre- and post-TACE model to predict tumor recurrence after living donor liver transplantation (MoRAL) (i.e., MoRAL score = 11×?protein induced by vitamin K absence-II + 2×?alpha-fetoprotein), which was proven to reflect both tumor burden and biologic aggressiveness of HCC in the explant liver, from a training cohort (n = 193). These results were externally validated in both an independent hospital cohort (from two large-volume centers, n = 140) and a Korean National Cancer Registry sample cohort (n = 149). RESULTS:The changes in MoRAL score (?MoRAL) after initial TACE was an independent predictor of OS (MoRAL-increase vs. MoRAL-non-increase: adjusted hazard ratio (HR) = 2.18, 95% confidence interval (CI) = 1.37-3.46, p = 0.001; median OS = 18.8 vs. 37.8 months). In a subgroup of patients with a high baseline MoRAL score (?89.5, 25th percentile and higher), the prognostic impact of ?MoRAL was more pronounced (MoRAL-increase vs. MoRAL-non-increase: HR = 3.68, 95% CI = 1.54-8.76, p < 0.001; median OS = 9.9 vs. 37.4 months). These results were reproduced in the external validation cohorts. CONCLUSION:The ?MoRAL after the first TACE, a simple and objective index, provides refined prognostication for patients with intermediate-stage HCC. Proceeding to a second TACE may not provide additional survival benefits in cases of a MoRAL-increase after the first TACE in patients with a high baseline MoRAL score (?89.5), who might be candidates for systemic therapy.
