Module 10: Tumor Immunology Flashcards
Define neoplasm
Abnormal tissue with rapid and uncoordinated growth
Benign or malignant
Define cancer
Cellular malignant tumor
Define carcinoma
Cancer of epithelial origin
Define sarcoma
Cancer of connective tissue origin (bone, muscle, vessels)
Define leukemia/lymphoma/myeloma
Cancer of blood cell origin
Define tumor
Swelling of a defined mass of tissue
Benign or malignant
Define benign
Localized growth, not malignant or recurrent
Define malignant
Growth that becomes progressively worse due to the disruption of normal cell function, invasion of healthy tissue, and metastasis
Define metastasis
Spreading form the primary location
Define invasive
Moving from tissues surrounding the primary site
Define protooncogene
Gene in a host cell which is involved in regulation of cell growth (proliferation, differentiation, survival)
Define oncogene
Gene that encodes a protein capable of inducing cellular transformation often through inappropriate cell growth
Tumor mechanisms to evade immune response (5)
Non-immunogenic Lack of adherence to lymphocytes Immunosuppressive cytokines Immunosuppressed Induce T regs to suppress anti-tumor immune responses
Major malignancy due to carcinoembryonic antigen (CEA) (oncofetal)
Colon cancer
Major malignancy due to alpha fetoprotein (AFP) (oncofetal)
Liver cancer, germ cell cancer
