[Experimental studies on antitumor effects of endogenously induced LAK (CTL) therapy for metastatic liver tumor].

Unlabelled: Antitumor effects of endogenously induced LAK (CTL) therapy by trans-hepatic arterial administration with OK-432 and rIL-2 for metastatic liver tumor were examined.

Results: The number of metastatic nodules (NMN) showed a significant correlation with the number of inoculated tumor cells. NMN of the treated group was significantly reduced over that of the saline group in cases of 2.
