Abstract

Introduction: Promyelocytic leukemia (PML) is a subtype of acute myeloid leukemia that frequently presents with a potentially fatal coagulopathy, therefore it represents a medical emergency. In the vast majority of patients, the t (15; 17) (q24; q21) occurs, which generates the aberrant gene PML-RARA. Using different cytogenetic and molecular biology techniques that detect these aberrations, it is possible to unequivocally diagnose the entity and study minimal residual disease.

Objective: To describe, compare and analyze cytogenetics and molecular biology techniques that are useful for diagnosis and follow-up of the patient with Promyelocytic leukemia. As well as pointing out its advantages and limitations.

Methods: A review of the scientific bibliography of the last five years related to the subject was carried out through PUBMED. An analysis and summary of the information was made.

Analysis and synthesis of the information: Two cytogenetic and three molecular techniques are described based on the application of the polymerase chain reaction. Its advantages and limitations are compared and analyzed.

Conclusions: Some of these techniques are only useful for diagnosis, while others, due to their high sensitivity, are recommended for monitoring the patient with Promyelocytic leukemia.
