Background: Arterial or venous thrombosis can complicate cancer, and 20% of cancer patients may develop venous thromboembolic disorders. Venous thromboembolism (VTE) is common in some haematologic malignancies and may coexist with thrombocytopenia in those haematologic malignancies. We carried out this survey to assess the knowledge and practice of haematologists and resident doctors in haematology in Nigeria regarding the management of thrombocytopenia and cancer-associated thrombosis., Methods: This was a survey that was shared electronically with participants who were consultant haematologists and resident doctors in haematology in Nigeria.., Results: There were 106 respondents, 70 (66%) of which were consultant haematologists. About a third (30.2%) of the respondents saw 6-10 patients with blood malignancies monthly. Fifty-seven (53.8%) of the respondents carried out risk assessment in their patients for cancer-associated thrombosis (CAT); 63 (59.4%) of the respondents saw 1-2 cancer patients with thrombosis in 3 months. The most common mode of treatment was pharmacological - 94 (88%) respondents used low molecular weight heparin. The most common haematologic malignancies associated with thrombocytopenia were acute leukaemias (69; 67%). The most common decision taken by respondents was to stop anticoagulants and transfuse platelets because the most frequent concern was the risk of bleeding in this group of patients., Conclusion: Many haematologists and haematology residents had a high level of awareness, knowledge and good practice regarding thrombocytopenia with CAT in haematooncology patients; however, there is a need for improved knowledge and unified protocols for treatment in line with newer management guidelines., Competing Interests: The Authors declare that no competing interest exists, (Copyright © 2023 by West African Journal of Medicine.)

Background: The successful treatment of patients with clonal hematological disorders (CHDs) depends largely on making an accurate diagnosis, which is, in turn, is dependent on performing specific diagnostic tests that are necessary., Objectives: This study assessed the laboratory investigative methods of diagnosing CHDs with regard to the specific required tests (SRTs) that were needed to make a final diagnosis in a center with limited resources., Methods: This is a descriptive hospital-based retrospective study. For the study, data about laboratory investigation details of adults diagnosed with CHDs from 1995 to 2015 were retrieved. The SRTs were determined and data analyzed using SPSS version 20., Results: A total of 129 case notes of adults in the age range of 18-80 years, diagnosed with CHDs, were used. Out of the 671 SRTs needed for diagnosis, only 304 (45.3%) were conducted. When an SRT was requested to be done within the treatment facility, the patients were significantly more likely to do it in comparison with when they were requested to get it done from an external referral laboratory. All the patients with aplastic anemia (AA) and paroxysmal nocturnal hemoglobinuria (PNH) had all (100%) their SRTs done while patients with non-Hodgkin's lymphoma (NHL) had the least (15.3%) of their SRTs done. Full blood count (FBC) was the most frequently used (n = 129; 100%) SRT for diagnosis while immunophenotyping (IMPT) was the least (n = 4; 8.3%) used SRT., Conclusion: Most of our patients had CHD diagnosis without the complete SRT, and this may cast doubt on the accuracy of diagnosis. Therefore, there is a crucial need for availability of more comprehensive laboratory services, especially in government-owned hospitals., Competing Interests: None

Background: Hematological malignancies are a significant cause of morbidity and mortality. They constitute an economic burden for the patients, their relatives, and the society because of the cost associated with their management, which is usually long term. We aimed to determine the total direct cost of managing patients with premalignant hematological disorders (PMHDs) and malignant hematological disorders (MHDs)., Materials and Methods: A hospital-based retrospective study was carried out between 1997 and 2015. Data were retrieved from the case notes of adult patients diagnosed with either PMHD or MHD. The total cost of medical care was calculated as the sum of in-patient and out-patient direct cost associated with their management. Data were analyzed using Statistical Package for Social Sciences., Results: There was a total of 129 patients; 74 (57.4%) males and 55 (42.6%) females with mean age of 45.7 ± 16.3 years and the majority (n = 76, 58.9%) being employed. Males were more affected than the females except in chronic lymphocytic leukemia, myelodysplastic syndrome, and paroxysmal nocturnal hemoglobinuria. The commonest MHD was chronic myeloid leukemia with 37 (28.7%) patients. Full blood count was the commonest investigation done, whereas free light chains were the least (n = 2; 1.6%). The total cost of care for the 129 patients was N30,041,900.00 ($82,306.58) with an average total cost of care per patient of N232,882.95 ($638.04). Patients with non-Hodgkin lymphoma had the highest mean cost of care per patient (N373,196.30; $1,022.46). The average monthly expenditure per patient was about N70,000 ($190)., Conclusion: In our setting, management of CHDs constitutes an economic burden., Competing Interests: There are no conflicts of interest.
