Transplantable Syngeneic Rodent Tumors

For many decades, the results from transplantable tumor models have been viewed with considerable skepticism. The perception has long been that these models are excessively sensitive, and not predictive of the human disease. Although we do not intend to debate the many issues involved, it is our view that a better understanding of the transplant properties (e.g., take-rate) of the models—as well as a better understanding of the potential shortcomings in data presentation—will greatly aid the reader in the interpretation of these data. This chapter is an effort to summarize some of the basic operating characteristics of a wide range of solid-tumor models. Since this is a chemotherapy group, we can best explain some of the behavioral characteristics of these models within therapeutic experiments. Most of the data is drawn from the use of transplantable, syngeneic mouse tumors, but a few human tumors have been used for contrast.
