ABSTRACT
Background/Aims@#Sorafenib is the standard of care in the management of advanced hepatocellular carcinoma (HCC). The purpose of this study was to investigate the characteristics, treatment patterns and outcomes of sorafenib among HCC patients in South Korea. @*Methods@#This population-based retrospective, single-arm, observational study used the Korean National Health Insurance database to identify patients with HCC who received sorafenib between July 1, 2008, and December 31, 2014. A total of 9,923 patients were recruited in this study. @*Results@#Among 9,923 patients, 6,669 patients (68.2%) received loco-regional therapy prior to sorafenib, and 1,565 patients (15.8%) received combination therapy with concomitant sorafenib;2,591 patients (26.1%) received rescue therapy after sorafenib, and transarterial chemoembolization was the most common modality applied in 1,498 patients (15.1%). A total of 3,591 patients underwent rescue therapy after sorafenib, and the median overall survival was 14.5 months compared to 4.6 months in 7,332 patients who received supportive care after sorafenib. The mean duration of sorafenib administration in all patients was 105.7 days; 7,023 patients (70.8%) received an initial dose of 600 to 800 mg. The longest survival was shown in patients who received the recommended dose of 800 mg, subsequently reduced to 400 mg (15.0 months). The second longest survival was demonstrated in patients with a starting dose of 800 mg, followed by a dose reduction to 400–600 mg (9.6 months). @*Conclusions@#Real-life data show that the efficacy of sorafenib seems similar to that observed in clinical trials, suggesting that appropriate subsequent therapy after sorafenib might prolong patient survival.
ABSTRACT
OBJECTIVES: We examined the agreement between the Autism Diagnostic Observation Schedule (ADOS) and the Childhood Autism Rating Scale (CARS) in the diagnosis of autism spectrum disorder. METHODS: The ADOS and CARS scores of 78 children were retrospectively collected from a chart review. A correlation analysis was performed to examine the concurrent validity between the two measures. Using the receiver operating characteristic (ROC) curve, we determined the optimal cut-off score of the CARS for identifying autism spectrum disorder. RESULTS: The CARS score was significantly correlated with the ADOS score (r=0.808, p < 0.001). Taking ADOS as the ideal standard, the optimal cut-off scores of CARS for identifying autism and autism spectrum were 30 and 24.5, respectively. CONCLUSION: We determined the optimal cut-off scores of CARS for screening and diagnosing autism spectrum disorder.
