Assessment of lymphatic involvement - lymphomas


        ASSESSMENT OF LYMPHATIC INVOLVEMENT - LYMPHOMAS
Cancers actually starting in lymph nodes are grouped together under the name lymphoma. In turn, lymphomas are subdivided into two groups— Hodgkin's disease and non-Hodgkin's lymphomas. Each of these groups contains a number of quite different subtypes. Hodgkin's disease tends to start in one group of nodes and spread in a fairly orderly and predictable way to other groups. Most non-Hodgkin's lymphomas tend to develop in many different groups of nodes at the same time, although there are a few particular types which spread like Hodgkin's disease. All lymphomas can also affect the bone marrow, liver, spleen and other organs.
Lymphomas can be treated by radiotherapy or chemotherapy. Hodgkin's disease and a few particular types of non-Hodgkin's lymphoma can be completely cured by radiotherapy, provided every involved node is treated. Here it is extremely important to track down every single deposit of the disease. In contrast, if chemotherapy is to be used, it is not as important to know where the disease is, because the chemotherapy drugs go right around the body anyway.
