Lipiodol retention patterns show no impact on overall survival in HCC

Key clinical point: The primary outcome of local recurrence-free survival was significantly longer for lesions showing complete retention than for those showing incomplete retention, but overall survival was no different based on lipidiol retention.  

Major finding: After propensity score matching of 121 pairs of lesions with complete/incomplete retention, the median local recurrence-free survival for lesions exhibiting complete retention was 1,279 days, compared to a median of 819 days in the incomplete retention group (P = 0.030).

Study details: The data come from 198 adult patients with a total of 280 HCC lesions who underwent transarterial lipiodol injection and thermal ablation at three centers between June 2014 and September 2020.

Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
