Abstract
Squamous cell carcinoma of tongue has a higher predilection for lymph nodal metastasis(1). Diagnosis of SCC of Tongue is by biopsy from tumor site, cytology from the lymph nodes, laryngoscopy, CT neck, and MRI(2). The management of N0 neck is controversial. The aim of this study is to evaluate the rate and site of occult metastasis and its correlation with characteristics of the primary lesion in tongue. This is a study done over 2 yrs. All patients with anterior 2/3rd of tongue with cN0 are included.
40 cases were included in the study. Occult metastasis are seen in 15 cases (37%), of which 4 cases had multiple levels of nodes metastasis. Extracapsular spread was also seen. Due to the lack of any investigations to find out N+ status in neck and similarity in disease free status between treated pN+ and N0 patients there is requirement for newer techniques in diagnosis of nodes. Tumor thickness should also be considered as a factor in treatment of early tongue cancers.
Keywords: Tongue cancer, SCC of Tongue, prophylactic neck dissection, diagnosis, biopsy, lymph nodal metastasis, node status, radiotherapy, Modified neck dissection, new techniques.
