Abstract

INTRODUCTION:

Neck dissection is an important part in the management of head and neck malignancies especially in terms of control of nodal metastasis. The study is focused on evaluating the profile of lymph nodes in T3N0M0 lesion of different subsides of oral cavity.

AIM:

To evaluate the utility of neck dissection in T3N0M0 stage of carcinomas of the different region of oral cavity.

MATERIALS AND METHODS:

Ninety patients aged 20 to 70 years underwent treatment for carcinoma of the oral cavity at our center between 2005 and 2013. Of these, 39 patients were stage T3N0M0 and underwent excision of the primary lesion with neck dissection. The data were collected retrospectively from hospital record library. These patients were evaluated clinically, radiologically and compared with intra operative finding. Addition of radiotherapy was decided on final histopathology.

RESULTS:

Out of 39 patients, the site of primary tumour in 21 patients was tongue, in 13 patients was Buccal Mucosa (BM), in 2 patients was lip and in 3 patients was Floor of Mouth (FOM) with tongue. In patients with clinically negative neck nodes, ultrasonography and intra-operative examination revealed the presence of suspicious nodes in 35.9% and 30.7% cases respectively. Occult metastasis in the nodes was identified on histopathological examination in 15 patients (38.5%). A total of 14 patients of carcinoma of tongue and one patient of BM showed positive nodes on histopathology. These patients with positive neck nodes on histopathology, were sent for postoperative radiotherapy. At follow up examination, four patients showed local and distal recurrence and they were managed accordingly. Out of 39 patients, 11 patients of BM, 2 patients of lip, 1 patient of FOM and 6 patients of tongue were disease free in last follow up.

CONCLUSION:

Selective neck dissection is an effective therapeutic intervention in patients without clinically involved neck nodes. It can upstage the tumour and additional treatment may be advised. In patients with carcinoma of buccal mucosa and lip, the patients can be kept under regular follow up when biopsy report showed excision with adequate margin and no nodal metastasis.
