Aims: Chronic lymphocytic leukemia is the most frequent adult leukemia in Western countries accounting for 25 to 30% of all leukemic patients. The clinical and haematological features vary from patient to patient. The aim of this study is to describe the clinical presentation of chronic lymphocytic leukemia, to evaluate haematological patterns of the disease in the peripheral blood and bone marrow and to correlate them with the clinical stage of the disease.
Study Design: This is a retrospective descriptive study.
Place and Duration: Radio Isotope Centre Khartoum (RICK), haematology laboratory during the period of January 2010 to December 2011.
Methodology: The data were collected at the haematology laboratory from patients’ records as well as from a special questionnaire designed for this study. Clinical data, complete blood count, bone marrow examination and immunophenotyping results were used.
Results: Out of 98 cases studied 69 (70.4%) were males and 29 (29.6%) were females. Sixteen patients (16.3%) were less than 50 years old (young patients) and 82 (83.7%) were more than 50 years of age (elderly patients). 49.1% of the patients were from western Sudan. Eight patients (8.2%) were asymptomatic. Absolute lymphocyte count above 5× 109/L had significant association with diffuse pattern of infiltration (P value=0.035) and was not significantly associated with advanced Rai stage (stage III 32.6%, Rai stage IV 22.8%) (P value=0.710).
Conclusion: Clinical and haematological pattern of chronic lymphocytic leukaemia in Sudanese patients has comparable results with previous studies in other parts of the world. Most of the patients were elderly male, from western Sudan presented with nonspecific symptoms, generalized lymphadenopathy and leukocytosis. The majority of patients presented in advanced stage at the diagnosis.
