Socio-economic class distribution of the prognostic variants of lymphoproliferative cancers in Nigerians

Abstract

One hundred and twenty Nigerians with various lymphoproliferative cancers were grouped according to socio-economic class and the prognosis of their disease. The best prognostic variant of acute lymphoblastic leukaemia occurred mainly in the highest socio-economic class and the worst variant mostly in the low socio-economic class. Chronic lymphocytic leukaemia, a low-grade malignancy, and the high grade Burkitt's type of Non-Hodgkin's lymphoma occurred predominantly in the low class. The relationship between prognosis and socio-economic class was not so remarkable in patients with Hodgkin's disease and multiple myeloma. The precise mechanisms by which socio-economic strata influence development of the different prognostic variants of individual lymphoproliferative cancers are not certain.
