These include leukemias, most lymphomas and germ cell tumors. Most mature lymphoid neoplasms comprise the non-Hodgkin lymphomas. These cancers include leukemias, lymphomas, and myelomas. Hodgkin lymphoma accounts for about 15% of lymphomas. The fatal diseases are leukemias, lymphomas, and non-regenerative anemias. Extranodal marginal zone B-cell lymphomas (also termed MALT lymphomas) are generally indolent malignancies. This occurs most commonly after the treatment of lymphomas and leukemias. Lymphomas and mesenchymal tumors may also develop in the stomach. Most lymphomas are tumours of B-cells. This is based on a physiological mechanism and is not pathogenetic for leukemias or lymphomas. The 2;5 chromosomal translocation is associated with approximately 60% anaplastic large-cell lymphomas (ALCLs). I Study in Adults With Relapsed Solid Tumors and Lymphomas is ongoing (2012). These transformed follicular lymphomas (t-FL) are essentially incurable. Common starlings may contract avian tuberculosis, avian malaria and retrovirus-induced lymphomas. The "Ak" in Akt refers to the AKR mouse strain that develops spontaneous thymic lymphomas.
