Abstract

BACKGROUND:

The incidence of Haematologic malignancies has been shown to vary according to gender, age, geographic region, and histologic subtypes, while cure rates can vary according to region and may be impacted by treatment availability and access to care.

METHOD:

This was an institution based review of data from the Medical Records Department, Department of Haematology and Cancer Registry of the Histopathology Department of the University of Maiduguri Teaching Hospital between January 1998 and December 2011. The aim was to study the spectrum of Haematologic malignancies and the survival pattern of adult lymphomas in this region and to compare our findings to studies reported elsewhere.

RESULTS:

The Haematologic malignancies represented 6.05% of all cancer cases seen and 0.31% of hospital admissions. Among the Haematologic malignancies, Non-Hodgkins Lymphoma (NHL) was the most frequent, constituting 51.3% while others include: Hodgkins Lymphoma (HL), 26.7% Chronic Myeloid Leukaemia (CML), 5.5%, Acute Myeloblastic leukaemia (AML), 4.2% Multiple Myeloma (MM), 4.2% Acute Lymphoblastic leukaemia (ALL), 3.8%, Chronic Lymphocytic Leukaemia (CLL), 3.4% Myelodysplastic Syndrome (MDS), 0.4% and Chronic Myelofibrosis 0.4%. Haematologic malignancies are more common in younger age group and also more common in males than females. Lymphomas are particularly common in young adults and the incidence tends to fall after 70 years. Similarly, the characteristic bimodal age incidence for HL found in western world has not been seen in this study. The histological subtypes for both NHL and HL are similar to the pattern reported elsewhere. Default rate was high and we found a strong association between cycles of chemotherapy given and survival in lymphoma patients.

CONCLUSION:

This study has shown that Haematologic malignancies are not uncommon in our environment. There is need to provide basic facilities and training for immunophenotyping and immunohistochemistry in all cancer treatment centers across the country. Cytotoxic drugs must be subsidized and also be made readily available to all patients with Haematologic malignancies.
