Combined Study of Cytogenetics and Fluorescence in Situ Hybridization (FISH) Analysis in Childhood Acute Lymphoblastic Leukemia (ALL) in a Tertiary Cancer Centre in South India

Abstract excerpt

FISH is one of the most sensitive molecular methods to detect genetic abnormalities with DNA probes. When cytogenetic studies are normal or insufficient, FISH may detect cryptic rearrangements, rare or slowly proliferative abnormal populations in non-mitotic cells. We cytogenetically evaluated 70 childhood ALL - 67.1% were found to have an abnormal karyotype. The 23 patients (32.9%) with a normal karyotype were...
