Pharmacogenetic Study in Hepatocellular Carcinoma Patients.

Overview

evaluate the prognostic value of genetic polymorphisms in HCC Egyptian patients undergoing TACE using lipiodol and doxorubicin.

Research Objectives This study aims to determine the predictive effect of ANG-2 and IL28B genetic polymorphisms in safety and efficacy of doxorubicin and lipiodol used for the treatment of Egyptian HCC patients. Moreover, this study will determine the association between genetic polymorphisms of ANG-2 and IL28B with HCC severity. Patients \& Methods Study design Our study is a prospective study for HCC patients undergoing TACE of doxorubicin and lipiodol. Sample Size Based on previous published incidence of gene it will be at least 116 patients. Efficacy and Safety 1. Target lesions response will be measured according to modified Response Evaluation Criteria in Solid Tumors (RECIST) to (15): Complete response, Partial response, Progressive disease and Stable disease. 2. Repeated TACE sessions will be planned individually based on the tumor response to the treatment protocol. 3. Follow up will be performed for detection of tumor size using triphasic CT scan as a measure of efficacy. Moreover, all patients will be reevaluated for CBC, liver and kidney functions, in the follow up visit, to detect incidence of any adverse effects. 4. Patients will be asked for any side effects such as (myelosuppression, anorexia, nausea, vomiting, and/or alopecia). 5. Patients will be followed for progression-free survival after receiving TACE. Method \& Proposal Steps 1. Approval will be obtained from Research Ethics Committee of Faculty of Pharmacy, Damanhour University. 2. Patients will be recruited from Ain Shams University hepatoma group, EL Demerdash Hospital, Cairo, Egypt. 3. At baseline and follow up visits after TACE, all patients will be assessed for complete blood count (CBC), kidney function, liver function, liver enzymes, alpha fetoprotein (AFP) and viral markers. Moreover, triphasic pelviabdominal CT will be performed before and after TACE. 4. Serum samples will be collected for ANG-2 and IL28B genotyping. 5. Genetic polymorphisms of ANG-2 and IL28B will be detected by real time polymerase chain reaction (RT-PCR). * Five mls of whole blood will be collected then separation of plasma will be performed. * Extraction of genomic DNA from blood samples by DNA extraction kit. * DNA qualification will be performed by Nano drop. * Genotyping will be done by allelic discrimination using Taqman assays specific for each polymorphism. * Assays will be done according to manufacturer protocol using real time PCR machine. 6. All patients will receive lipiodol and doxorubicin during TACE. Doxorubicin dose will differ among patients according to tumor size, patient condition, patient's laboratory data and presence of hepatic arteriovenous fistula. 7. Appropriate statistical tests will be conducted to evaluate the significance of the results. 8. Results, conclusion, discussion and recommendations will be given.
