Resumen
This article examines the significance of liquid biopsies in the field of thoracic oncology, particularly regarding the diagnosis and treatment of malignancies. These blood-based biopsies, which utilize circulating tumor DNA (ctDNA), are presented as a less invasive method for both the diagnosis and monitoring of cancer cells and offer a dynamic means of tracking tumors, allowing for personalized treatment approaches and real-time information about the tumor?s status throughout its natural history. The analysis of biomarkers through blood samples could therefore lessen the need for more invasive tissue biopsies. The article also addresses the valuable role circulating biomarker analyses play in allowing treatment plans to be modified according to the genetic changes observed in the tumor. The importance of adapting to genetic aberrations that may develop during treatment is highlighted, emphasizing the need for timely adjustments to ensure a therapy?s effectiveness. In summary, the article underscores the potential of liquid biopsies to revolutionize thoracic cancer care by offering a minimally invasive and personalized approach to diagnosis and treatment, emphasizing the importance of their further advancement.
