(2016) Changing pattern of haematological malignancies in Ilorin, Nigeria: A 10 year retrospective review of 181 cases. Annals of Medical Research. 5:1 - 6.http://hdl.handle.net/123456789/4033Abstract The global burden of cancer has been reported to be on the increase and haematological malignancies (HM) are not exceptions to this observed trend. The aim of this study was to carry out a retrospective analysis of all cases of HM seen at the University of Ilorin Teaching Hospital, Ilorin and document the current pattern of HM and compare with previous reports from Nigeria and elsewhere. Materials used for the study were obtained from the Records Cancer Registry of the University of Ilorin Teaching Hospital. A total of 181 cases of HM were diagnosed and managed within the study period constituting 8.1% of all cancer cases and 0.2% of all hospital admissions. The ages of patients with HM ranged from 7 months to 80 years. There were 116 (64.1%) males and 65 (35.9%) females. The various HM recorded in the study were: ALL 17(9.4%), AML 23(12.7%), CLL 33(18.2%), CML 46(25.4%), NHL 33(18.2%), HL 7(3.9%), BL 2(1.1%) and MM 20(11.0%). CML was the commonest HM observed in this study. NHL was the commonest lymphoma encountered constituting 82.5% of all the lymphoma cases. This study demonstrated that haematological malignancies are common in this environment. Availability of improved diagnostic facilities, improved blood transfusion services, early presentation and better referral system from other health facilities to our centre may have contributed to the improved mean survival of patients with HM observed in this study.enPattern,Haematological,RetrospectiveMalignancies,Ilorin,Article
