Selective internal radiation therapy using yttrium-90 resin microspheres in patients with unresectable hepatocellular carcinoma: a retrospective study.

BACKGROUND: Selective internal radiation therapy (SIRT) with yttrium-90 resin (Y-90 resin) microspheres has been used as a locoregional therapy for patients with unresectable hepatocellular carcinoma (HCC). We examined patient and disease characteristics that might affect survival after Y-90 resin, as well as treatment tolerability. METHODS: Data from patients with unresectable HCC treated with Y-90 resin at a single institution were reviewed retrospectively. Survival was assessed with Kaplan-Meier curves and log-rank tests. Response was evaluated with the response evaluation criteria in solid tumors (RECIST) criteria. Adverse events (AEs) were noted, and laboratory values were graded with CTCAE v3.0. RESULTS: Data from 111 patients were analyzed. AEs occurred in 23 patients at 1 week after treatment and in 46 at 3 months. At 6 months, 13 patients had a complete response and 13 had a partial response. Factors associated with longer overall survival (OS) included early-stage disease [27.8 months for patients with Barcelona-Clinic Liver Cancer (BCLC) A vs. 9.2 months for BCLC C]; treatment with other locoregional therapies (69.0 vs. 11.4 months); and lack of bilobar disease (23.5 vs. 9.4 months), portal vein thrombosis (16.2 vs. 8.6 months), ascites (16.6 vs. 10.3 months), and treatment with sorafenib (17.2 vs. 10.3 months). In six patients, Y-90 resin was used as a bridge to liver transplantation, which greatly improved survival (69.0 vs. 12.1 months). CONCLUSIONS: Several characteristics may prove useful for selecting patients likely to respond well to Y-90 resin. These results should be confirmed in prospective studies.

Spontaneous bacterial peritonitis before liver transplantation does not affect patient survival.

BACKGROUND & AIMS: Spontaneous bacterial peritonitis (SBP) is a devastating complication of cirrhosis with high mortality. The impact of a prior episode of SBP on the outcome of liver transplantation (LT) is not well known. We aimed to determine the short- and long-term morbidity and mortality of patients who received LT, with and without a history of SBP. METHODS: We reviewed the records of all adult patients who underwent LT at a single center between June 1999 and June 2009. Patients with SBP were compared with all other patients who underwent LT during the same time period, without prior episodes of SBP. RESULTS: A total of 1491 adult patients underwent LT in the study period; 80 (5.4%) had at least 1 episode of SBP before LT. The mean follow-up time for all patients in the study was just over 4 years. Patients in the SBP cohort were more likely to be male (74%) and to have alcoholic liver disease. Patients with SBP had higher Child-Pugh and model for end-stage liver disease scores at the time of transplantation compared with controls, but there was no difference in long-term mortality between the 2 groups. Patients with SBP, however, were more likely to require surgery for complications related to LT within 1 year and were more likely to die of sepsis. CONCLUSIONS: Despite higher Child-Pugh and model for end-stage liver disease score at the time of LT, survival times of patients with SBP before LT are similar to those patients without SBP.
