BCLC subclassification and tumour characteristics to provide prognostication of outcomes in an Asian population of locally advanced hepatocellular carcinoma treated using selective internal radiation therapy with Yttrium-90.

443Background: Selective internal radiation therapy (SIRT) with Yttrium-90 (Y90) is preferentially used in locally advanced hepatocellular carcinoma (HCC) patients in the Barcelona clinic liver cancer (BCLC) B or C cohort. However, the BCLC B cohort has a wide heterogeneity. To address this, Bolondi et al. proposed a BCLC B subclassification system. Additionally, the BCLC C cohort is also diverse in their Child-Pugh (CP) stage and extent of portal vein thrombosis (PVT). The effect of these subclassifications on survival outcomes has not been studied in HCC patients treated using SIRT. Methods: 392 HCC patients treated using SIRT from 1st January 2008 to 17th March 2017 were analyzed. These patients were classified according to the proposed subclassification system for the BCLC B cohort, and CP stage for the BCLC C cohort, and their survival outcomes reviewed. Results: 293 patients met the study’s inclusion criteria. For B1/B2/B3/B4/ C CP-A and C CP-B, the median OS was 48.3/28.7/14.4/13.7/12.8 and 6.6 mon...
