During the terminal phase, the animals should be inspected and continually assessed for early termination several times each day [daily according to BU policy]. The HSC-3 bearing tumors have (E,F) ulcers, (G) neural, and (H) vascular invasion (arrows). All tumor-bearing animals must be observed on a scheduled basis and findings documented to assess the progress of tumor growth and/or metastasis, and the general condition of the animal.

(10)Health Evaluation of ExperimentalLaboratory Mice Non Binding Agreement To Follow Common Policies, Recent advances in the development of new methods of cancer immunotherapy require the production of complex cancer animal models that reliably reflect the complexity of the tumor and its microenvironment. Animals with newly transplanted tumors may require only routine observation [3x/week according to BU policy] during the early stages of tumor development; however, animals in the terminal stages of tumor-associated disease or drug toxicity may require monitoring several times a day., The incidence and growth rate of spontaneous tumors, some chemically induced tumors, or those arising in transgenic animals may be difficult to predict. The purpose of this policy is to provide guidelines for tumor implantation and monitoring for rodents inoculated with Neoplastic cells or toxic agents and for rodents that are genetically predisposed to develop tumors. Use of body condition scoring as an adjunct endpoint for tumor growth studies. 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. Clinical extravasations of paclitaxel may be treated by subcutaneous injections of hyaluronidase diluted in saline. Scale bars, 0.2 cm (E), 400 m (F), and 200 m (G,H).

Tumors were most frequently found in the skin, with each mouse typically having multiple firm, slow-growing tumors, and the mice had to be euthanized 2-4 months after tumor appearance, usually because of tumor ulceration and occasionally because of limb paralysis . 1. The presence of ulceration of the tumor is generally a criterion for euthanasia. In addition, human tumor lines require IBCInstitutional Biosafety Committee Sites involving the face, limbs or perineum, as there is little to no space for tumor growth and expansion, and resulting tumors may interfere with eating and drinking.
