[Regional arterial chemoembolisation and chemoimmunoembolisation in combined treatment of colon cancer with hepatic metastases]. / Regionarnaia arterial'naia khimioémbolizatsiia i khimioimmunoémbolizatsiia v kompleksnom lechenii raka tolstoi kishki s metastazami v pechen'.

Results of locoregional intraarterial treatment with recombinant Interleukine-2 (Ronkoleukine) in patients with hepatic metastases of colon cancer are presented, efficacy of locoregional arterial chemoembolisation and chemoimmunoembolisation in combined treatment of hepatic metastases are evaluated. The drugs were administered through catheter installed in the right or left branch of the own hepatic artery with Selinger method. Endovascular treatment was carried out 6-10 months after removing of primary tumor. In group 1 (8 patients) infusion of 5-fluororuracil during 3 days (2.0 g/day) with subsequent intraarterial immunoembolisation with recombinant Interleukine-2 (Ronkoleukine) 2 mln IU and 10.0 ml lipiodol were performed. In group 2 (13 patients) infusion of 5-fluororuracil during 3 days (2.0 g/day) with subsequent intraarterial chemoembolisation with Doxorubicin 60 mg/kg and 10.0 ml lipiodol were carried out. All the patients underwent cytoreductive surgery on the liver (in the scope from segmentectomy to hemihepatectomy). The patients of group 1 are alive, mean follow-up from removing primary tumor is 22.8 +/- 7.4 months, from start of endovascular treatment--9.2 +/- 2.3 months. Patients of group 2 died due to progression of disease, mean survival from removing primary tumor was 25.7 +/- 4.2 months, from start of endovascular treatment--7.6 +/- 6.3 months. In group 1 postembolic syndrome with transient fever and chill was seen, in group 2--fever, plains in epigastric area, increase of transaminases in blood, abscesses of metastatic tumors (n = 2) and alopecia (in all patients). It is concluded that regional arterial chemoimmunoembolisation is a perspective and safe method in combined treatment of colon cancer with hepatic metastases compared with locoregional chemoembolisation. It increases lifespan and improves quality of life.

[Selective-occlusive method of drug administration in the treatment of experimental liver tumors]. / Selektivno-okkliuzionnyi metod vvedeniia preparatov pri lechenii éksperimental'nykh opukholei pecheni.

263 experimental studies on 184 rats were carried out. Hepatic tumors were provoked by intraparenchymatous implantation of 0.1 ml 20% tumoral suspension of mucous cancer (RS-I). Treatment was realized on 10-12 day after vaccination. Photodynamic therapy with "Photosense" (PS) and laser irradiation (670 nm, 50-100 Dj, 4-13 mm), and also catalytic therapy (CT) with "Teraftal" (TF) and ascorbic acid (AA) were used. FS and TF were administered by developed selective-occilisive method (SOM). Rapid accumulation of drugs in occluded lobe of liver was revealed in SOM, that permitted to decrease administered dose of TF in 16.5 times. There was no growth of tumor after FDT unlike control group. Same results were obtained after CT with SOM, but there was further growth of tumor after systemic administration of drugs. Developed SOM of drugs administration in FDT and CT lead to good results in treatment of experimental hepatic tumors.
