Adult Leukemia in the Niger delta region of Nigeria.

Objective: To determine the incidence and survival of patients with Leukaemia in the Niger Delta region of Nigeria, noted for its petrochemical industries. Design: A prospective study of 120 cases of leukaemia from December 1993 to 2003. Setting: University of Benin Teaching Hospital, Nigeria. Main Outcome measures: Demographic and clinical information including duration of illness before presentation was obtained by oral interview. Results: Chronic Myeloid Leukaemia (CML) was the most frequent subtype (33.3%). There was a strong association between the white blood cell count at presentation and 1 year survival in CML and CLL patients (p= 0.0001). The 2-year survival for CML, CLL and PLL was 12.5%, 40% and 32% respectively. Duration of illness before presentation was found to influence 1-year survival in CML (p=0.0075) and CLL (p= 0.0001). Conclusion: The 2-year survival is still very poor and this may not be unconnected with late presentation and other strong limiting factors.
