OBJECTIVE was to evaluate the results of transcatheter arterial chemoembolization (TACE) in the treatment of patients with hepatocellular carcinoma (HCC) on advanced liver cirrhosis (LC) and intermediate stage (B) according to BCLC classification (Barcelona Clinic Liver Cancer classification).METHODS AND MATERIALS. We evaluated results of TACE in 54 patients. Of them, 12 (22 %) had stage A of cirrhosis and 42 (78 %) – stage B of cirrhosis according to the Child-Pugh score. Nine (17 %) patients matched stage A4 and 45 (83 %) – stage В according to BCLC classification. The TACEs was performed according to the conventional practice with using Lipiodol + gelfoam (n=40) and with a drug-eluting beads (n=14) from 1 to 16 (average 6) times. The Doxorubicin was used as a first-line therapy in all cases.RESULTS. After TACE, two patients died of liver failure (3.7 %). According to the m-RECIST, complete response to treatment was observed in 9 (16.5 %), partial response – in 13 (24 %), stabilization – in 19 (35.5 %) and progression – in 13 (24 %) patients. At present, 22 (41 %) patients are alive for 1 to 51 (average 16.2) months. 32 patients (59 %) died between 2 to 62 months: 13 (24 %) – from HCC progression, 19 (35 %) – from liver failure. The 1– 2–3-year survival rate was 75–44–15 %; only one patient survived > 5 years. The median survival rate was (22.0±3.0) months, overall survival rate according to Kaplan – Meier was 26 months.CONCLUSION. TACE is a relatively safe and effective treatment in patients with HCC on advanced LC and intermediate stage (B).

Radiopharmaceutical with rhenium-188 and lypiodol is synthesized in medical organizations from a kit of reagents and eluate from the 188W/188Re generator. The kit of reagents consists of three vials: lyophilized reagent N 1 containing tin dichloride, lyophilized reagent N 2 - sodium dithiobenzoate, and reagent N 3 - lipiodol. A domestic technology was developed for obtaining a lyophilized reagent containing tin dichloride. Quality control of the sodium perrhenate, 188Re solution obtained from the generator (eluate) should be carried out before each synthesis of the radiopharmaceutical. The results of quality control of radiopharmaceuticals synthesized from lyophilized reagent N 1 of domestic and imported production, showed their identity by index «radiochemical purity».
