Introducción: El cáncer de mama (CaMa) es el tipo de cáncer con una alta tasa de mortalidad y su diagnóstico oportuno, permitiría una mayor probabilidad de sobrevivencia. Actualmente hay diversos procedimientos para su detección, sin embargo, una posible alternativa no invasiva mediante la detección de compuestos orgánicos volátiles (COV) en el aliento (exhalómica) de las pacientes se está explorando. Métodos: Se realizó una revisión sistemática (hasta junio de 2022) de publicaciones sobre la detección mediante cromatografía de gases de COV en el aliento de mujeres con mama sana, con lesiones benignas o invasoras y en líneas celulares, para buscar potenciales oncometabolitos. Resultados: Existe una gran heterogeneidad de COV (principalmente alcanos) en las pacientes analizadas, además de diferencias entre las distintas poblaciones. Discusión: Aun cuando hay detección de COV exhalados, es necesario un mayor número de estudios. De manera interesante, un grupo de COV son compartidos con otros tipos de cáncer. Conclusiones: Al momento, no se conoce el perfil de COV exhalados asociados con certeza al paciente de CaMa.
Background: Breast cancer (BrCa) presents a highest mortality rate, and its early diagnosis could improve the survival of the patient. At present, there are leading tests used for BrCa detection, but a novel alternative, non-invasive test, such as breath analysis (exhalomic) of volatile organic compounds (VOCs), are being taken into consideration. Methods: A systematic review (until June 2022) about VOC detection from breath using gas chromatography was performed. The goal was to identify probable oncometabolites in the gas sample from healthy breast tissue women, benign, or malignant lesions, and including cultured cell lines. Results: There are a complex heterogeneity of exhaled VOC mainly alkanes in the analyzed samples, and between the different populations. Discussion: Even when exhaled VOC is detected, some more works should be performed to have conclusions. Interestingly, some VOC is shared with other cancer types. Conclusions: Nowadays, there is no specific BrCa VOC-profile associated for BrCa or benign lesions diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
