LBA1 Background: HCC is the 3rd cause of cancer death globally with most deaths occurring within 1 year of diagnosis. No standard therapy exists for advanced HCC. Sorafenib (Sor) is a multikinase inhibitor with anti-angiogenic, pro-apoptotic and Raf kinase inhibitory activity, with clinical activity in a phase II HCC trial. This large, multicenter, randomized, placebo-controlled phase III trial evaluated the efficacy and safety of Sor vs placebo (P) in pts with HCC. Methods: Patients with advanced measurable HCC, no prior systemic treatment, ECOG PS 0–2 and Child-Pugh status A received Sor 400 mg bid or P. Primary efficacy endpoints were overall survival (OS) and time to symptomatic progression (TTSP). Time to progression (TTP) and disease control rate (DCR; CR+PR+SD for at least 2 cycles) were secondary endpoints.Treatment arms were compared for OS and TTSP using a 1-sided log-rank test [overall a of 0.02 (OS) and 0.005 (TTSP)] stratified by region, ECOG PS and tumor burden. An O’Brien-Fleming-type error spending function determined criteria for early stopping for efficacy. Results: 602 pts (Sor n=299; P n=303) were randomized. Baseline characteristics were similar for Sor vs P: median age (67 vs 68 y), male (87% vs 87%), ECOG PS 0 (54% vs 54%), Child-Pugh A (95% vs 98%), and BCLC stage C (82% vs 83%). Based on 321 deaths (Sor n=143; P n=178), the hazard ratio (HR) for OS (Sor/P) was 0.69 (95% CI: 0.55, 0.87; p=0.0006), representing a 44% improvement in OS vs P which met early stopping criteria. Median OS was 10.7 vs 7.9 mos (Sor vs P). Primary TTSP analysis demonstrated no statistically significant difference for Sor vs P. HR for TTP (independent assessment) was 0.58 (95% CI: 0.45, 0.74; p=0.000007). Median TTP was longer (5.5 vs 2.8 mos) and DCR was higher (43% vs 32%) with Sor vs P. Incidence of serious adverse events was similar for Sor vs P (52% vs 54%). The most frequent grade 3/4 events were diarrhea (11% vs 2%), hand-foot skin reaction (8% vs 1%), fatigue (10% vs 15%), and bleeding (6% vs 9%) for Sor vs P. Conclusions: Sorafenib was well tolerated and is the first agent to demonstrate a statistically significant improvement in OS for pts with advanced HCC. This effect is clinically meaningful and establishes sorafenib as first-line treatment for these pts. [Table: see text]
We demonstrated that, when performed in pediatric patients, the correlation between endoscopic middle meatal culture and maxillary sinus puncture was not as favorable as in the case of adult patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
