Background: Hematological malignancies represent a group of cancers arising from blood and lymphatic tissues with substantial
diversities in clinical and biological characteristics. To best of our knowledge, there is a paucity of data regarding these cancers from
KSA. Therefore, the aim of the present study was to identify the epidemiologic patterns of leukemia and lymphoma in the Hail
region, the northern kingdom of Saudi Arabia (KSA). Methodology: Data regarding 120 patients with leukemia or lymphoma were
retrieved from the King Khalid Hospital in Hail. Data included all patients with a diagnosis of leukemia or lymphoma during the
period from 2008 to 2016. Results: Out of the 120 patients 73/120(60.8%) were diagnosed with leukemia and 47/120(39.2%) were
diagnosed with lymphomas. Of the 73 patients with leukemia, 43/73(58.9%) were males and 30/73(41.1%) were females. Of the 47
patients with leukemia, 27/47(57.4%) were males and 20/47(42.6%) were females. Conclusion: Leukemia was more predominant than
lymphoma in Hail area and males were more susceptible than females for both cancer types.
