Abstract

BACKGROUND AND OBJECTIVES
This study aimed to evaluate the clinical efficacy of sentinel node centered selective neck dissection in patients with early stage tongue cancer (T1T2N0).
SUBJECTS AND METHOD
Lymphoscintigraphy was performed for 12 patients, subsequently followed by sentinel node centered selective neck dissection. The location of the sentinel node, pathological confirmation of node metastasis, and follow-up recurrence were analyzed.
RESULTS
In total, 19 sentinel lymph nodes were identified. Of these, 18 were located in levels I to III, and one in level IV. After surgery, 3 patients (25%) were diagnosed with neck node metastasis: two experienced sentinel node metastasis and one experienced skipped metastasis. During follow-up, 3 of the 12 patients (25%) experienced recurrence.
CONCLUSION
The recurrence of lymph node could be covered with supraomohyoid neck dissection, which indicates that it has superiority over sentinel node centered selective neck dissection in preventing recurrence in T1T2N0 tongue cancer patients.
