or TIL cells to test their cytologic function. When possible, we 
will derive autologous cell lines to be used as targets in a *^Cr 
release assay. Finally, every attempt will be made to excise 
tumor tissue prior to treatment for diagnosis, 
immunohistochemistry, and cryopreservation and to evaluate 
delayed type hypersensitivity reactions to the tumor before and 
after treatment. 
11.4 Toxicity 
Toxic side effects of treatment will be analyzed and 
classified by the common toxicity criteria (Section 13) .
