Popis: | We have previously reported that the combination of murine recombinant interferon beta (Mu-rIFN beta) with murine recombinant interferon gamma (Mu-rIFN gamma) provided greater inhibition of tumor growth than did each one alone in MethA-bearing mice. In the present study the effect of addition of human recombinant interleukin-2 (Hu-rIL-2) to the combination of Mu-rIFN beta with Mu-rIFN gamma on tumor growth in BALB/c mice bearing syngeneic MethA fibrosarcoma was examined. Low doses of Hu-rIL-2 (5 x 10(3) U or 5 x 10(4) U at 3-day intervals) showed no antitumor activity, while a high dose of Hu-rIL-2 (5 x 10(5) U) showed profound growth inhibition. The administration of IL-2 (ranging between 5 x 10(3) U and 5 x 10(5) U) in addition to the combination of IFN beta and IFN gamma showed more augmented antitumor effects in a dose-dependent manner. Furthermore, the simultaneous administration of IL-2, IFN beta and IFN gamma had more effective therapeutic activity, compared with the sequential administration of interferons and IL-2. These findings indicated that IL-2 in combination with IFN beta and gamma was effective for cancer treatment. |
