Detection of 13q deletion in patients with chronic lymphocytic leukemia and its correlation to hematopathological parameters

“…Indeed, this result is similar to the trend that appeared in most published articles which have pointed to the fact that the disease is more common in men than in women with a ratio of 2:1 (92)(93)(94) . In a recent Iraqi study, the male to female ratio was 2:1 which is in agreement with the finding of the current study (91) .…”

“…Moreover, in the current study, only 13.3% were younger than 55 years of age; this is in accordance with the National Cancer Institute's Surveillance and Epidemiology End Results (SEER) database, which revealed that 11% of all patients diagnosed with CLL in 2009 were less than 55 years of age (90) . In a recent Iraqi study (91) , it has been found that the median age of patients with CLL was 65 years which is approximately similar to that of the present study. Moreover, Iraqi cancer registry has postulated that the leukemia rank the third of all hematopoietic malignant diseases in Iraq according to the Iraqi cancer registry 2015; it has an average incidence 4.08 cases per 100,000, while the incidence of CLL ranges from <1 to 5.5 per 100,000 people in worldwide (10) .…”

“…Those results were comparable to many studies (95,101,102) . In one study, thrombocytopenia was identified in 18 % of patients with CLL (96) , a figure that is approximately similar to that of the present study; however, it is lower than that described by Hasan et al who stated that thrombocytopenia was identified in 60 % of cases (91) . Thrombocytopenia was usually attributed to bone marrow failure.…”

Management of Chronic Lymphocytic Leukemia in Less-Resourced Countries

“…A final point worthy of discussion is related to the benefit of developing local treatment guidelines for CLL, which may help the medical community in less-resourced countries to address constraints not necessarily relevant to guidelines from international societies. 2,[39][40][41] To our knowledge, local guidelines from the countries represented here have only been developed more recently in Argentina 42 and in Brazil 28 and in 2005 in Uruguay. 43…”

“…25,26 In addition to the registry, the Brazilian Group of CLL was created in 2013, with the aim of providing treatment recommendations and foster patient enrolment in clinical trials. 28 With a population of 3.4 million inhabitants, Uruguay is one of the smallest countries in South America and has an ethnic distribution that comprises 87.7% of Whites, 4.6% of Blacks, 2.4% indigenous, and 5.3% other or unspecified. 23 The Uruguayan Society of Hematology started a National Registry of hematologic malignancies in 2008.…”
