Abstract
- These results indicate that extensive, multiple cervical micrometastases occurred from an early stage in patients with T2N0 tongue cancer. The presence of micrometastases suggests the necessity of preventive neck dissection for Level I–IV nodes as a radical treatment. Cervical lymph node metastases occur with a relatively high frequency in patients with T2N0 squamous cell carcinoma of the tongue, and control of the metastases greatly influences the prognosis of patients. In this study, micrometastases in the cervical lymph nodes were investigated to clarify the necessity and required extent of preventive neck dissection. We investigated micrometastases in 24 subjects who had previously been diagnosed with T2N0 tongue cancer. We performed immunostaining with anti-cytokeratin antibody cocktail AE1/AE3 of sections of 401 paraffin-embedded lymph nodes obtained from these patients. Micrometastases were observed in 14 patients (58%) and were most abundant in Level II nodes ( n =11; 46%). Micrometastases were observed in the Level IV nodes of 3 patients (13%), and upstaging to pN2b occurred in 7 patients (29%). [ABSTRACT FROM AUTHOR]
