Zusammenfassung: Evaluierung der kombinierten Therapie bestehend aus transarterieller Chemoembolisation (TACE) und lokaler Immunotherapie des hepatozellul(a) ren Karzinoms (HCC) am Kleintiermodell. Bei m(a)nnlichen ACI-Ratten (n=30) erfolgte nach subkapsul(a)rer Implantation eines soliden Morris Hepatoms (2 mm3) in den linken Leberlappen (Tag 0) die magnettomographische Tumorvolumenbestimmung (V1: Tag 13). Nach retrograder Katheterisierung der Arteria gastroduodenalis wurden die Tiere entsprechend den folgenden Therapieschemata behandelt (Tag 14): (A) TACE (0,1 mg Mitomycin C+0,1 ml Lipiodol)+( TNF (7,5μg)+IL-2 (5×103IU) (n=10); (B) TACE+OK-432 (0,05 mg) +IL-2 (5×103 IU) (n=10); (C) TACE allein (Kontrollgruppe, n=10). Zu Beurteilung des Therapieerfolges der unterschiedlichen Behandlungsprotokolle wurde das Tumorvolumen (V2) erneut magnettomographisch ermittelt (Tag 28). Das durchschnittliche Tumorvolumenverh(a)ltnis (V2/V1) betrug 7,30, 6,53 und 9,14 in Gruppe A, B und C. Im Vergleich zur Kontrollgruppe zeigten die Therapiegruppen A (P
