[Regional chemotherapy of liver tumors].
Based on experience with regional intrahepatic chemotherapy in 67 patients with inoperable primary, and in particular secondary liver tumours, which comprises several hundred administered cycles of mostly continuous regional regimens, the authors summarize briefly the main principles and possibilities of this treatment. In a review of randomized studies they provide evidence for the advantage of regional chemotherapy, as compared with systemic treatment, in particular with regard to the higher percentage of therapeutic responses. In correctly indicated, and if possible early cases of hepatic tumourous affections, it is possible to potentiate the effect of regional chemotherapy by local destruction of tumourous foci by alcoholization, cryodestruction or resection. An integral part of this treatment is also monitoring of the effect by following up the dynamics of serum levels of tumour markers and by imaging methods. Because the most frequent cause of failure of this method are extrahepatic secondaries and secondary chemoresistance of the tumourous foci, improvement of results can be expected in particular from a combination of regional and systemic chemotherapy and the inclusion of cytokines into the therapeutic schemes.
