A survey on transarterial chemoembolization refractoriness and a real-world treatment pattern for hepatocellular carcinoma in Korea.

ABSTRACT:

Background/aims

Transarterial chemoembolization (TACE) is a standard treatment for intermediate-stage hepatocellular carcinoma (HCC), but there is much controversy about TACE refractoriness. The aim of this study was to identify trends in the actual clinical application of TACE and recognition of TACE refractoriness by Korean experts.

Methods

In total, 17 questionnaires on TACE refractoriness were administered to 161 clinicians via an online survey. Multiple answers were allowed for some questions.

Results

Most clinicians agreed that there is a need for standardization of TACE application through specific scoring systems (n=124, 77.0%). TACE refractoriness was predominantly expected by participants when recurrences were detected within 1 month (n=70, 43.5%), there were 4 to 6 tumors (n=77, 47.8%), the maximal tumor size was 3-5 cm (n=49, 30.4%), and when there was insufficient tumor necrosis despite TACE being repeated more than three times (n=78, 48.4%). Overall, sorafenib therapy (n=137) and radiotherapy (n=114) were preferred when repeated TACE was considered ineffective.

Conclusion

Treatment of HCC is often based on the clinical judgment of clinicians because of the heterogeneity among individuals. Experts need to continue discussions on the standardization and sub-classification of HCC treatment guidelines in Korea.

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.
