For Non-Hodgkin’s lymphoma first division is according to the type of cells: B-cell lymphoma (90%), T-cell lymphoma (10%) and NK cell lymphoma (1% in known cells). Other type of division available is by its rate aggressiveness. It is divided into indolent type (slow growing, may not require treatment) or aggressive NHL (grows rapidly, requires rapid management). NHL is also divided into subtypes. These subtypes determine if it should be treated or just monitored. These subtypes od B-cell lymphoma include: diffuse large B-cell lymphoma (aggressive but treatment responsive), Follicular lymphoma (in lymph nodes, indolent and responsive to radiotherapy), Mantle cell lymphoma (in older people, have cyclin D proteins, Slow growing and responds to chemo + monoclonal antibodies), small lymphocytic lymphoma (B cell CLL, indolent, does not require treatment), primary mediastinal lymphoma (aggressive, SVC syndrome) and Burkitts lymphoma (aggressive). T-cell lymphoma subtypes: anaplastic large cell lymphoma (indolent) (systemic and cutaneous), breast implant-associated anaplastic large cell lymphoma, peripheral T-cell lymphoma and angioimmunoblastic T-cell lymphoma.
