Acceleration of B16 melanoma growth in mice after blood transfusion. 1987

D M Francis, and C P Burren, and G J Clunie

Evidence suggests that blood transfusions depress immunologic reactivity; as some tumors are influenced by the immune status of their host, it is possible that transfusions could promote tumor growth by impairing host immunity. The influence of blood transfusion on the growth of a transplantable B16 melanoma was examined in nude (athymic) CBA mice and immunocompetent C57 BL/6J mice. Recipients were given infusions of saline solution or syngeneic or H-2-incompatible allogeneic blood transfusions on two occasions 3 days apart. Infusions were begun 10 days before inoculation of a single cell suspension of B16 melanoma. Growth was determined by measurements of primary tumor volume and tumor weight after excision. There was no statistically significant difference in tumor size or weight between the three recipient groups of athymic mice. However, immunocompetent mice given H-2-incompatible allogeneic blood had higher rates of tumor engraftment--saline solution recipients versus allogeneic recipients: chi 2 = 13.2, df = 1, p less than 0.001; syngeneic recipients versus allogeneic recipients: chi 2 = 2.97, df = 1, p greater than 0.05. In the allogeneic group significantly larger and heavier tumors developed than in mice given syngeneic blood or saline solution. The study indicates that H-2-incompatible allogeneic blood transfusions can influence the growth of a transplantable murine tumor by a mechanism that involves a cell-mediated immune response.

D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D006128	Growth	Gradual increase in the number, the size, and the complexity of cells of an individual. Growth generally results in increase in ORGAN WEIGHT; BODY WEIGHT; and BODY HEIGHT.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
