CADENA, Enrique  e  DE LOS REYES, Carmen Amelia. SPECT/CT for lymphatic mapping of sentinel nodes in carcinoma of oropharynx. rev.colomb.cancerol. [online]. 2014, vol.18, n.3, pp.149-153. ISSN 0123-9015.  https://doi.org/10.1016/j.rcc.2014.08.001.

The diagnosis of oropharyngeal cancer is difficult because the initial symptoms are unusual, is evident some times when the patient has a large tumor. To realize appropriate treatment is essential to know if existing nodal infiltration, more even when the standard management is surgical resection, in the last decade is robot-assisted transoral surgery. The microscopic positive lymph node depends on the level of infiltration of the tumor and may be up to 40%. The lymphatic mapping of sentinel nodes is make by lymphoscintigraphy, its accuracy improves when the images are obtained with SPECT/CT. Recently, we did this study in a patient with a tumor at the base of tongue, confirming the presence of a sentinel node of IIA level. The main advantage was the anatomical accuracy when we make fusion of images with SPECT/CT.
