RESUMO
Background. Identification of patients with advanced HCC-deriving preferential benefit from sorafenib is desirable, and treatment-related adverse events are potential clinical biomarkers. Methods. Survival and toxicity data for patients with HCC treated with sorafenib at the Christie NHS Foundation Trust from 11/09 to 02/15 were collected retrospectively. Results. Eighty-five eligible patients were identified. The most common grade 3 or 4 treatment-related toxicities were hypertension (HTN, 45 %), fatigue (8 %), and hand-foot syndrome (HFS, 8 %). Any-grade HFS and/or worsening HTN (HFS/HTN) were experienced by 58 % of patients. Estimated median progression-free and overall survival (OS) were 4.6 (95 % CI 2.8-5.2) and 6.5 (95 % CI 4.9-8.01) month-p value <0.001) and the development of HFS/HTN were independent prognostic factors impacting on OS on multivariable analysis. Patients who developed HFS/HTN had median OS of 8.2 months (95 % CI 6.5-12.4) compared with 4.1 (95 % CI 2.7-5.4) for those without this toxicity (Hazard Ratio (HR) 0.4, 95 % CI 0.2-0.7, p value 0.003). The prognostic impact of HFS/HTN was confirmed by landmark analyses limited to patients who lived a minimum of 2 months (p value 0.019) or who developed HFS/HTN in the first 3 months of treatment (p value 0.006). Conclusion(s). The development of toxicities specific to sorafenib is associated with prolonged survival in a UK-based HCC patient series; prospective assessment of their significance is required (AU)
