ABSTRACT
Hematological and hematopoietic cells malignancies of the genes and hematopoietic cells are associated with the genetic mutation, often at the chromosomal level. The standard cytogenetic study is widely accepted as one of the main diagnostics and prognostic determinants in patients. Therefore, the current descriptive and cross sectional study sought to determine the cytogenetic analysis of frequent hematological malignancies in Pakistan. A total of 202 peripheral bone marrow or blood samples from patients with benign and malignant hematological malignancy were taken using a conventional G-banding technique. Among enrolled patients, the mean age was 21.5 years ± 23.4, and gender-wise distribution showed a marked predominance of the male 147 (73%) population compared to the female 55 (27%). Patients in the age group (2-10 years) had the highest frequency, 48 (24%), of hematological neoplasms, followed by age (11-20 years) with 40 (20%). Normal karyotypes (46, XX/46, XY) was found in 51% (n=103) patients. Furthermore, the frequency of complex karyotype was 30 (15%), while normal was seen in 171 (85%) patients. Pre-B Acute Lymphoblastic Leukemia (Pre-B ALL) was the most prevalent malignancy of 66 (33%), followed by Chronic Myelogenous Leukemia (CML) of 41 (20%) and Acute Lymphocytic Leukemia of 29 (14%). Translocation was the most prevalent 50 (25%), followed by hypotriploidy 14 (7%) and monosomy 8 (4%) on chromosome aberration analysis. In addition, t(922) translocation was found to be 20 (10%) in CML, with the majority in the age group (31-40 years). This study recommends that karyotyping should be tested frequently in hematological conditions because it may provide insight into the relative chromosomal changes associated with particular malignancies.(AU)
RESUMO
As neoplasias hematológicas e de células hematopoiéticas dos genes e as células hematopoiéticas estão associadas à mutação genética, geralmente em nível cromossômico. O estudo citogenético padrão é amplamente aceito como um dos principais determinantes diagnósticos e prognósticos em pacientes. Portanto, o presente estudo descritivo e transversal buscou determinar a análise citogenética de neoplasias hematológicas frequentes no Paquistão. Um total de 202 amostras de medula óssea periférica ou sangue de pacientes com malignidade hematológica benigna e maligna foi coletado usando uma técnica convencional de banda G. Entre os pacientes inscritos, a média de idade foi de 21,5 anos ± 23,4, e a distribuição por gênero mostrou uma marcada predominância da população masculina de 147 (73%) em comparação com a feminina de 55 (27%). Pacientes na faixa etária (2-10 anos) tiveram a maior frequência, 48 (24%), de neoplasias hematológicas, seguida da idade (11-20 anos) com 40 (20%). Cariótipos normais (46, XX / 46, XY) foram encontrados em 51% (n = 103) dos pacientes. Além disso, a frequência de cariótipo complexo foi de 30 (15%), enquanto normal foi observada em 171 (85%) pacientes. Leucemia linfoblástica aguda pré-B (LLA Pré-B) foi a doença maligna mais prevalente de 66 (33%), seguida por leucemia mieloide crônica (LMC) de 41 (20%) e leucemia linfocítica aguda de 29 (14%). A translocação foi o 50 mais prevalente (25%), seguido por hipotriploidia 14 (7%) e monossomia 8 (4%) na análise de aberração cromossômica. Além disso, a translocação t (922) encontrada foi de 20 (10%) na LMC, com a maioria na faixa etária (31-40 anos). Este estudo recomenda que o cariótipo deve ser testado com frequência em condições hematológicas porque pode fornecer informações sobre as alterações cromossômicas relativas associadas a doenças malignas específicas.(AU)
