Impact of Neck Dissection in the Treatment of Oral Squamous Cell Carcinoma

Abstract

he clinical outcome of the overall recurrence after SND and RND in the treatment of oral squamous cell carcinoma; relate the recurrence rate of pathological staging and the significance of PORT in reducing recurrence. Fifty-eight Neck Dissection (ND) was done in 57 patients with oral squamous cell carcinoma in Ramadi Teaching Hospital, Iraq from 2008 to 2014. In the first group there were 33 SND which were done in the clinically negative neck (cN0) and in the second group there 25 RND which were done in the clinical positive neck (cN+). Postoperative radiotherapy was given to six patients with cN0 and to 19 patients with cN+. There were four recurrences in the first group (3 cases, ND without PORT, 1 case ND with PORT) and 6 recurrences in the second group (4 cases ND without PORT, 2 cases ND with PORT). there is a significant difference in tumor recurrence in the pathological positive neck (pN+) than the pathological negative neck (pN0) (9.6 times more recurrences in pN+). Tumor recurrence was not influenced statistically with the use of postoperative radiotherapy PORT in the clinically negative neck. There was a significant difference in recurrence in the clinical positive neck (cN+) (p- value >0.05). These findings support general acceptance of the use of END in the clinically negative neck without PORT and RND for clinical positive neck combined with PORT in selected cases to obtain a low recurrence
