[Significance of typing in the survival of malignant lymphomas]

The significance of typing and subtyping in the survival rate of 116 patients suffering from pathologically proved malignant lymphoma is presented. Our data show that Hodgkin's disease was least malignant, having the highest survival curve (P less than 0.005). Lymphoblastic lymphoma had the highest degree of malignancy, having the lowest survival curve. Yet, the middle portion of its curve resembled that of the peripheral T cell lymphoma. Although the degree of malignancy and the curve of peripheral T cell lymphoma and B cell lymphoma were similar (0.05 greater than P greater than 0.05), their middle portion were separated, a fact worthy of further study. Typing of malignant lymphomas is of practical importance.
