Background Non-Hodgkin lymphomas are a heterogeneous group, which involve either B or T lymphocytes. The most used treatment is a chemotherapy regimen, which includes cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone combined with rituximab - a monoclonal antibody specific for CD20 - an antigen expressed on B lymphocyte membrane. Nonmelanoma skin cancers are the most common forms in patients who have lymphomas.
