PURPOSE: To evaluate the influence of sarcopenia on survival in patients with hepatocellular carcinoma (HCC) treated with 90Y radioembolization.
MATERIALS AND METHODS: This single-center retrospective cohort study analyzed 82 consecutive patients (65 men and 17 women, mean age 65 years, range 31-83 years) with HCC treated with 90Y radioembolization between December 2013 and December 2017. Sarcopenia was assessed on pre-procedure MRI performed within 100 days prior to 90Y radioembolization by segmenting the paraspinal musculature at the level of the superior mesenteric artery origin and subtracting fat-intensity pixels to yield fat-free muscle area (FFMA). Sarcopenia was defined as FFMA ≤31.97 cm2 for men and ≤28.95 cm2 for women. Survival at 90 days, 180 days, 1 year, and 3 years following initial treatment was assessed using medical and public obituary records.
RESULTS: Sarcopenia was identified in 30% (25/82) of patients. Death was reported for 49% (32/65) of males and 71% (8/17) of females (mean follow-up 19.6 months, range 21 days-58 months). Patients with sarcopenia were found to have increased mortality at 180 days (31.8% vs. 8.9%) and 1 year (68.2% vs. 21.2%). Sarcopenia was an independent predictor of mortality adjusted for BCLC stage and sub-analysis demonstrated that sarcopenia independently predicted increased mortality for patients with BCLC stage B disease.
CONCLUSION: Sarcopenia was associated with increased 180-day and 1-year mortality in HCC patients undergoing 90Y radioembolization. Sarcopenia was an independent predictor of survival adjusted for BCLC stage with significant deviation in the survival curves of BCLC stage B patients with and without sarcopenia.
