Second malignancies in non-Hodgkin's lymphoma

Abstract
Six hundred thirty cases of non‐Hodgkin's lymphoma (NHL) in the Tumour Registry of Manitoba spanning an 11‐year period from January 1968 to December 1978 were reviewed. There were 34 cancers from 31 individuals who developed the cancer at least six months after diagnosis of NHL. There was no statistical difference in the incidence of second malignancies in this disease compared with an age‐matched population in Manitoba. In particular, no cases of acute leukemia were identified.
