          Abstract

          4586

          Background: For HCC pts undergoing LT, loco-regional treatment as a "bridge" is standard. The best bridging modality is unclear. SBRT is safe and effective when used in pts with advanced HCC. We prospectively compared SBRT to TACE as a bridge for HCC pts undergoing LT. Methods: From 9/2014-10/2019, 60 pts within Milan Criteria with CTP Class A/B8 cirrhosis were consented. 54 pts were randomized to TACE vs. SBRT. TACE pts (n =30) were scheduled to receive 2 treatments one month apart utilizing DEBDOX beads. TACE pts were hospitalized after each TACE. Pts receiving SBRT (n =24) received a median total dose of 45Gy delivered over 5 fractions using fiducials. Mean liver dose, Veff, and NTCP determined prescription dose. Pts were assessed by using mRECIST criteria at 2 months and every 3 months thereafter until LT or death. Toxicity and QOL were assessed before treatment, during treatment, two weeks post-treatment, and then every three months using the PIQ-6 Pain Impact Questionnaire and the SF-36v2 Health Survey. The 1° endpoint was time to recurrent or residual dz. Secondary endpoints were toxicity, pathologic response, radiologic response, number of subsequent treatments, cost, and QOL. 50 pts are evaluable for review. Results: See table. Conclusions: For early stage HCC patients with CTP Class A/B liver cirrhosis, SBRT appears as effective as TACE at controlling HCC prior to LT, may engender less toxicity, and eliminates the need for hospitalization. A larger multi-center trial is ongoing. Clinical trial information: NCT02182687. [Table: see text]
