Observational Prospective Study on Chemoembolization With Doxorubicin for Unresectable Hepatocellular Carcinoma

Study Overview
=================
Brief Summary
-----------------
Hepatocellular carcinoma (HCC) is the fifth most common type of cancer in men and the seventh in women and is the third most common cause of death from cancer worldwide. The overall incidence of HCC remains high in developing countries and is steadily rising in most industrialized countries. TACE with Doxorubicin-eluting beads (DEB-TACE) has recently been developed as a novel therapy option for HCC. In order to maximize its therapeutic efficacy, doxorubicin-loaded beads were developed to deliver higher doses of the chemotherapeutic agent and to prolong its permanence within the tumor. The comparison of efficacy and safety of TACE with drug-eluting microspheres in comparison with conventional TACE (cTACE) showed that response and time to progression in the group was significantly higher than that of the cTACE group. TACE with drug-eluting microspheres thus appears to be a feasible and promising approach to the treatment of HCC. This study's purpose is evaluating treatment efficacy, survival rate and safety of TACE using drug-eluting microspheres loaded with doxorubicin for unresectable hepatocellular carcinoma.

Detailed Description
-----------------
This study's purpose is to assess treatment efficacy, survival rate and safety of TACE using drug-eluting microspheres loaded with doxorubicin for unresectable hepatocellular carcinoma. Study Design: Prospective observational study . Primary objective: To collect data on tumor response after administration of drug-eluting microspheres that were preloaded with doxorubicin. Secondary objectives: To collect data on survival rate, time to progression, tolerability of treatment, number of treatment required to achieve objective response and improvement of quality of life. Treatment method: Day -1 Doxorubicin at a dose of 35/50 mg/m2 has been charged onto 2 ml of microspheres at Pharmacy. It is suggested to dissolve Doxorubicin powder with 2 ml of contrast medium. The charging time of microspheres is at least 30 minutes. Day 0: prehydration, antibiotic prophylaxis and setting up of a therapeutic scheme appropriate for analgesic prophylaxis (3-day duration) as previously reported (17) Day +1: Upon admittance to the radiology room, 1 vial of tropisetron (diluted in 100ml of physiological solution) and 1 vial of morphine hydrochloride diluted in 100 ml i.v. are administered by slow drip. One vial of morphine hydrochloride diluted in 100 ml i.v. to be repeated one hour after the procedure and if necessary also after 6 hours. Tropisetron i.v. if needed. Intra-arterial premedication (optional) with 1 vial of verapamil diluted in 4 ml of normal saline solution followed by 4 ml of lidocaine. Tumor Infusion (segment/s with dominant disease) of Doxorubicin at a dose of 35/50 mg/m2 preloaded into 2 ml of 70-150 µm M1 microspheres. A second tumor infusion is allowed if other lesions are present (daughter tumor), using Doxorubicin at a dose of 35/50 mg/m2 preloaded into 2 ml of 70-150 µm M1 microspheres (following radiologist and oncologist ' s planning of cure). Day +30: The above procedure is repeated. Day +90: In case of response, a third administration following the above procedures will be repeated Evaluation of response Response is assessed at 30, 90 and 180 days after TACE, monitoring tumor dimension using Chest-abdomen CAT scan with and without contrast medium, and cancer markers (CEA, Carbohydrate Antigen (CA) 19.9) Tumor response is performed according to the Response Evaluation Criteria In Solid Tumors (RECIST) criteria. Assessment of quality of life Assessment of quality of life with alliative Performance Scale PPSv2 is performed during the baseline visit and 30, 60 and 180 days after treatment.
