La biopsia líquida en el diagnóstico y monitoreo de pacientes oncológicos: oportunidades y retos en Latinoamérica

ABSTRACT   In recent years, the study of circulating nucleic acids has made great progress in the field of oncology, allowing for significant advances in clinical applications of liquid biopsy in diverse areas such as prognosis, staging, recurrence prediction, selection and monitoring of treatments, among others. This advance is largely due to the development of new and better technologies, some of which have even been validated for the diagnosis and clinical follow-up of certain types of cancer. However, the use of liquid biopsy as an additional tool in clinical oncology remains under study. Given the worldwide importance of this technological advance, a literature review was conducted to establish the current status of the use of liquid biopsy in oncology, as well as its current clinical applications, with a particular focus on Latin America.
