The recent improvements in the outcomes of patients with acute lymphoblastic leukemia reflect the progress in the field of diagnostics and the achievements in therapeutic interventions. In particular, the availability of more advanced technology in the cytogenetic and molecular laboratories has resulted in the stratification of patients into specific risk groups and thus several novel agents as well as targeted therapies have been introduced. Additionally, precision medicine will be applicable in the near future and thus the recent developments will facilitate the provision of safer modalities of therapy that may ultimately yield not only higher responses but also improved survival rates.
This review represents a recent update on the role of various cytogenetic assays and molecular techniques in patients with acute lymphoblastic leukemia. It is composed of a number of sections including: history of cytogenetics, disease etiology and pathophysiology, utilization of various cytogenetic assays diagnostically, disease-specific cytogenetic and molecular abnormalities, common disease genetic subtypes, prognosis and risk stratification, refractory and relapsed disease, novel therapies, precision medicine and drug repurposing.
