MOPC-315 murine plasmacytoma as a model anticancer screen for human multiple myeloma.

The murine tumor MOPC-315 plasmacytoma was studied as a model for human multiple myeloma. Plasmacytoma cells (10(6)) were injected iv into BALB/c mice, and 14 days later a single ip dose of the anticancer agent to be tested was administered at a dose that would result in 10% toxicity within 30 days (LD10). Increases in life-span and cures resulting from the LD10 dose were the parameters assessed. The response of this MOPC-315 plasmacytoma model to a variety of anticancer agents demonstrated good correlation with clinically active agents. A number of investigational agents were found to be highly active and potential candidates for clinical phase II studies.
