Quantitative evaluation of anticancer agents against human melanoma cells implanted in nude mice.
BRO human melanoma cells, which are exceptionally tumorigenic and lethal for nude mice, were inoculated intraperitoneally or intracerebrally in varying numbers. An inverse linear correlation was observed between the logarithm of the number of cells inoculated and host survival. In mice bearing 10(7) cells intraperitoneally, 2.4-2.8 log10 units of cell kill were obtained after a single intraperitoneal injection of vincristine, and some mice inoculated with 10(5) cells were cured by this treatment. Fewer cells were killed by L-phenylalanine mustard. Vincristine did not prolong survival of nude mice with intracerebral BRO tumors. Cell kill after administration of anticancer agents can be quantitated for BRO cells inoculated intraperitoneally or intracerebrally.
