[Cytokines in regional immunochemotherapy of liver tumors].
Regional intrahepatic chemotherapy of inoperable primary and secondary liver tumours can achieve, as compared with the little effective systemic chemotherapy, a higher percentage of therapeutic responses. The objective of regional chemoimmunotherapy, i.e. the use of cytokines, in particular interferon alpha (IFN-a) and interleukin-2 (IL-2) in the therapeutic regimens is to improve the survival of patients with malignant liver tumours. One of the main prerequisites of the effect of locally administered cytokines is activation of hepatic lymphocytes (LAL)-liver associated lymphocytes, effectors with specific phenotype and potential anti-tumourous effect directly in the target area. Although in regional monotherapy the effectiveness of cytokines is low, regimens combining the administration of cytostatics with IL-2 achieve a 50-70% therapeutic response. The authors summarize basic data on the regional administration of cytokines and present an review of combined regimens of regional chemoimmunotherapy, including their own protocol of the Masaryk Oncological Institute in Brno.
