Abstract

Background: HCC accounts for approximately 90% of all primary liver cancers, and is the fifth most common cancer in the world and prognosis is so far very poor,particularly in E patients.Between all tentative of treatment till know SFB seems to be the most promising drug in patients with advanced or metastatic HCC.Aim of the study is to investigate if SFB is efficient and safe also in E HCC patients despite the comorbidities and other problems. Objectives: To investigate if CgA and VEGF work as predicting factors of Sorafenib treatment outcomes. Methods: 51 patients, mean age 68,9 (65-85) with HCC were enrolled . Serum CgA, VEGF and αFP were evaluated at baseline and after end of treatment (SFB 400mg p.o. bid), until disease progression. Clinical response (RECIST), Comprehensive Geriatric Assessment and PFS were considered as well. Results: CgA mean value (baseline: 77.9 – after treatment: 26.25 UI/L) and VEGF levels (baseline: 67.3 – after treatment 47.2 pg/ml) seems to have a predictive role in clinical benefit. A correlation between lower values of CgA and VEGF was noted in pts with longer PFS. Furthermore 3-4 toxicity was not observed in these pts. OS median was 11 months. Conclusions: The most relevant data in this study refer to the role of serum CgA and VEGF levels, for prediction of tumor response. If these findings were confirmed in future largest studies, it could be sufficient to measure these markers levels for identification of those HCC patients who have more probability of obtaining clinical benefit from a sorafenib treatment.
