Effect of Intralesional Interleukin-2 on Murine Bladder Tumor / 대한비뇨기과학회지

ABSTRACT

PURPOSE: We tried to evaluate the anticancer effect of intralesional interleukin-2 on murine bladder tumor. MATERIALS AND METHODS: In vitro direct anticancer effect of interleukin-2 upon MBT-2 cells was examined using MTT colorimetric assay in various concentration of human recombinant interleukin-2. Also in vivo study was carried out measuring the tumor implantation rates and growth of the implanted tumors on C3H/He mice receiving six consecutive injections of various concentrations of interleukin-2. RESULTS: No definite direct anticancer effect was found on in vitro study. Also, the tumor implantation rate and growth of the implanted tumors were similar whether interleukin-2's were injected or not. CONCLUSION: Intralesional injection of interleukin-2 does not seem to be effective upon murine bladder tumor.
