Time of death of CNS tumor-bearing rats can be reliably predicted by body weight-loss patterns. In the absence of reliable laboratory-based assays, animals with leukemia or lymphomas should be observed for early clinical signs such as anemia, loss of condition or weight, and enlargement of the spleen and lymph nodes.

Humane endpoints, as listed in this policy, are determinants for euthanasia. Fig. Scoring systems from 1 (emaciated/wasted) to 5 (obese) are often used (see Appendix A for detailed descriptions and corresponding images). Low-level whole body irradiation or immunosuppressive agents are frequently used to further suppress the immune response of immunodeficient rodents before inoculation with human tumor xenografts. Syngeneic mouse models are used for efficacy testing of immuno-oncologic drugs and the investigation of the effects of conventional anti-cancer drugs on the immune system.

Weight Loss in Cancer Mouse Models. FOIA Tumor burden should be determined by evaluation of the Body Condition Score (see BCS figure below), size of tumor(s), anatomical location, incidence of multiple tumors, tumor appearance, and other clinical signs, as noted below. Specifically, since there are differences in normal behavior between different mouse and rat strains, the responsible research staff must be familiar with the animal(s) on study BEFORE the experiment begins. var sibErrMsg = {"invalidMail":"Please fill out valid email address","requiredField":"Please fill out required fields","invalidDateFormat":"Please fill out valid date format","invalidSMSFormat":"Please fill out valid phone number"}; Those who dislike or have .
