Localised nodal non-Hodgkin's lymphoma--a study of 42 cases treated by radiotherapy.

The records of 42 patients with stage I and II nodal non-Hodgkin's lymphoma treated by radiotherapy with and without chemotherapy were analysed with regards to clinical presentation, investigations, treatment, radiotherapy techniques and results. The 5-year overall survival rates for all, low grade, intermediate grade and high grade histology types are 69.5%, 100%, 64.4% and 46.9% respectively. The 5-year relapse-free survival rates of those treated by initial radiotherapy alone for all, low grade and intermediate-high grade histology types are 54.8%, 46.9% and 59.4% respectively.
