CORRELATION OF TRISOMY 12 WITH CLINICAL FEATURES AND OTHER LABORTARY PARAMETERS IN PATIENTS WITH CHRONIC LYMPHOCYTIC LEUKAEMIA
Objective: To determine the frequency of trisomy 12 in B-Cell chronic lymphocytic leukaemia (CLL), to correlate its association with clinico-pathologic features and to determine the role of this cytogenetic defect to the prognosis. Study Design: Cross sectional study. Place and Duration of Stu...

| Sumario: | Objective: To determine the frequency of trisomy 12 in B-Cell chronic lymphocytic leukaemia (CLL), to correlate its association with clinico-pathologic features and to determine the role of this cytogenetic defect to the prognosis.
Study Design: Cross sectional study.
Place and Duration of Study: Haematology department, Armed Forces Institute of Pathology, Rawalpindi, from May 2017 to Aug 2018.
Methodology: A total of 56 newly diagnosed patients of Chronic Lymphocytic Leukaemia were included in the study. Patients were diagnosed on the basis of National Cancer Institute Working Group guidelines. A detailed history and thorough clinical examination were performed and complete blood counts, biochemical profile, bone marrow examination, immunophenotyping on bone marrow/peripheral blood samples were done for the diagnosis of Chronic lymphocytic leukaemia. Interphase FISH studies were performed on blood/bone marrow aspiration for detection of Trisomy 12 were performed.
Results: Out of 56 patients, trisomy was detected in 12 (10.7%) patients. Out of 7 patients with trisomy 12, five patients presented in late stages (Binet stage B and C), however this association of Trisomy 12 with Binet stage was also statistically insignificant (p=0.474). About six with trisomy 12 were positive for CD 38, however this association was also not statistically significant (p=0.124). Results revealed that patients having trisomy 12 underwent chemotherapy at diagnosis and during follow ups as compared to patients having other cytogenic abnormalities. Moreover, patient with trisomy 12 develop progression in disease during course of illness, however association was statistically insignificant (p>0.05)............ |
