[Combined effect of human recombinant interferon-beta and interferon-gamma against an experimental model of peritonitis carcinomatosa in nude mice].

The development of useful therapy for the peritonitis carcinomatosa of gastrointestinal cancer is an important theme in cancer therapy. We developed an experimental model of peritonitis carcinomatosa in nude mice transplanted intraperitoneally human colon cancer cells. In this study, we investigated combined effect of human recombinant interferon-beta (rIFN-beta) and recombinant interferon-gamma (rIFN-gamma) in vivo using this model. The result indicate that each rIFN-beta and rIFN-gamma showed a significant prolonged survival compared with the control group (mean survival days: 41.8 +/- 5.0 days). Furthermore, combined administration of rIFN-beta and rIFN-gamma showed a marked prolonged survival (mean survival days: 114.0 +/- 7.4 days) compared with rIFN-beta or rIFN-gamma alone. These results suggest that a combined treatment of rIFN-beta and rIFN-gamma may be useful against peritonitis carcinomatosa of gastrointestinal cancer.
