Ulcerating cancers are sometimes called fungating cancers (tumours) or wounds. Ulceration of the skin overlying or surrounding tumors should result in removal of the animal from the study and euthanasia. The experiment ended for individual mice either when the tumour size exceeded 1500 mm 3, the tumour showed ulceration, the mouse was seriously ill, tumour growth blocked the movement of the mouse .

Humane endpoints, as listed in this policy, are determinants for euthanasia. Humane Endpoints and Cancer Research | ILAR Journal | Oxford Academic A secondary tumour is a tumour that has spread from a primary site to other parts of the body. 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. Production of mouse tumor models for evaluation of immunotherapy. Perpendicular widths of skin ulcers were measured by caliper and multiplied to yield a lesion area in cm2.

Boil. Tumor cell survival assays may be used as surrogate endpoints in place of limiting clinical signs or death of the host., Spontaneous tumors can arise in most tissues, and their development most closely resembles the clinical course. Scientific endpoints should precede limiting clinical signs such as consistent weight loss, clinical anemia, apathy, impaired respiration, or death., Ascitic tumors, abdominal distension, anemia, solid tumor deposits, and loss of condition are associated with the development of ascites.

None of the topical adjuvants or other ID adjuvants significantly reduced paclitaxelinduced skin ulcers in the mice. However, those models can have some limitations: many of those studies use immunocompromised mice, with a subcutaneous implantation of the tumor tissue, which prevent immune responses and site specific interactions (3), thereby losing crucial features of the tumor microenvironment.

About ulcerating cancers (fungating tumours) - Cancer Research UK Evaluating liquid tumors (e.g., leukemia) and non-palpable tumors in central areas of the rodents body (e.g., bone, brain and lungs) can be challenging. The tissue was chopped into a fine paste, resuspended in DMEM + L-Glut, Pen-Strep and 20% FBS, and plated out in a 25cm flask. Standard endpoints can be based on the indicators below, and used to develop a scoring system: Additional endpoints specificto cancer models (suchas tumor size, tumor ulceration, ability to ambulate) or specific to the known pathology of the particular model used, can also be taken into account(12, 13).
