a study of comparison of tace combination with and without ebrt for advanced hcc

Conditions: Hepatocellular Carcinoma

Summary: this clinical trial is a prospective, randomized, controlled and multicenter study.and the trial is going to better control intrahepatic tumors for hepatocellular carcinoma(hcc) patients who meet the inclusion criterion.the patients were divided into two groups, the group a by tace and the other group b by external- beam radiotherapy(ebrt) after 2 times tace. then the therapeutic effects and toxicities of tace and ebrt are evaluated during the follow-up period. the study design plans to enroll 300 patients, and each group includes 150 cases.

enrolled hcc patients met the inclusion criterion, in the late or advanced stage,tumor confined in intrahepatic( meet the tolerance-dose for the liver), without cancer embolus in main branch of portal vein, without extrahepatic metastasis and the number of tumor was≤3. eligible participants will be randomly assigned to the group a by tace and the other group b by ebrt after 2 times tace. tace group: the frequency of treatment is determined based on the disease condition for patients who are randomly assigned to group of tace.tace is performed via an injection into the hepatic artery of agents by puncturing the common femoral artery, and micro-embolization superselective catheterization is preferred.adriamycin(30 to 60mg) is considered as basic chemotherapy drugs in the process of transcatheter endovascular perfusion.the dose of fluid lipiodol was determined by diameter and blood supply type of hcc,generally 5-20ml, and no more than 30ml once.the boundary is considered whether there are large amounts of lipiodol to deposit in the tumor and tiny branches shadow of portal veins in paracarcinoma under fluoroscopic guidance. embolizing agents(gelatin sponge particles 350um-560um) are added after lipiodol emulsion embolization.it has a possibility of observeation alone if tumor achieves a complete response after two times tace. ebrt group: patients who were randomized to the radiotherapy group start radiotherapy 3-5 weeks after the completion 2 times tace and began to undergo radiation. radiotherapy equipment is based on the conditions of the cooperative units. 3-dimensional conformal radiation therapy(3-dcrt), intensity-modulated radiation therapy(imrt) or image-guided radiotherapy(igrt) will be opted based on hospital. igrt can also be used via helical tomotherapy, rapid arc or volumetric modulated arc therapy(vmat). the target volume should include the visible tumor.

Eligibility criteria:
1. inclusion criteria 1）initially diagnosed hcc (confirmed by pathology or meet clinical diagnostic criteria), 2）the patients are not candidates for curative surgery, which should be determined in consultation with two oncology surgeons of the same center, 3）tumor was confined in intrahepatic( meet the tolerance-dose for the liver), without cancer embolus in main branch of portal vein, without extrahepatic metastasis and the number of tumor was≤3, 4）child-pugh a，white blood cell count \>2\*109/l、hb\>90g/l、plt\>50\*109/l, 5）the score of eastern cooperative oncology group(ecog): 0-2, 6）the estimated survival time \> 3 months, 7）without midsection history of radiation therapy, 8）age: \>18 years old, 9）informed consent was signed. 2. exclusion criteria 1）diffuse hepatocellular carcinoma, 2）uncontrollable infection, 3）concurrent other malignant tumors, 4）simultaneously participate in other experimental drugs or clinical trials, 5）serious of heart, lung and kidney diseases, 6）during pregnancy and lactation, 7) the ones with severe neurologic morbidity couldn't clearly tell therapeutic response. 3. halfway exit criteria 1）do not treat according to the research or seriously violate the fundamental principles after enrolled, 2）cannot tolerate radiation therapy, including the ones that cann't complete the radiation treatment( the dose \<40 gy,biological effective dose \<48 gy), or interrupt more than 2 weeks during radiotherapy, 3）unwilling to continue this clinical trial.
