| Research Abstract |
To evaluate the feasibility of a diagnostic imaging focused on high risk lymph node using CT lymphography in cN0 tongue cancer. In our study, "high risk lymph node" is correspond to so called "sentinel node". In our result, particularly CT lymphography was useful to visualize the in-transit lymph node close to the primary tumor and the lymph pathway draining through the para-hyoid area.
Recurrent lesion at para-hyoid area showed poor treatment results and the prognosis, however the sentinel node biopsy of the lingual lymph node is not considered realistic because of its deep location.
From the viewpoint of the prediction of the para-hyoid recurrence, we can check whether a lymphatic drainage pathway from the tongue passes through the medial side of the submandibular gland or not by using CT lymphography.
