Non-Hodgkin's lymphomata: clinical features in relation to histology

An analysis is given of the clinico-pathological correlations of non-Hodgkin's lymphomata in 332 patients referred to the Netherlands Cancer Institute in Amsterdam and the Rotterdam Radiotherapy Institute. Clinical staging proved to be an important prognostic index. In Stage I the 5 year survival was 55%, in Stage II 25% and in Stages III and IV less than 10%. The presence of follicular structures in non-Hodgkin's lymphomata has similarly an important prognostic significance especially in Stage I and II. In lymphocytic lymphomata a larger cell size is correlated with less favourable prognosis. The presence of macrophages in non-Hodgkin's lymphomata is found in patients with short survival. The histiocytic lymphomata have a different survival pattern from the lymphocytic lymphomata in Stages I and II.
