چکیده انگلیسی:
Background: The occult neck metastasis rate is very high with tongue cancers. The aim of this study was to assess the current role of elective neck dissection (END) in management of early-stage oral tongue cancer with a focus on lymph node metastasis. In addition, effects of END on regional or systemic disease recurrence and survival were investigated. Methods: This retrospective study included patients with stage I and II tongue cancer recruited from our National Cancer Institute (NCI) over a time period of six years (2007-2013). The collected data were analyzed for disease free survival (DFS) and recurrence rate. Results: A total of 144 patients presented to our NCI with oral tongue cancer but only 88 were staged clinically and radiologically as early stage (stage I, stage II). Some 53% were smokers. Most lesions were dealt with by surgery, either by wide local excision (22%) or hemiglossectomy (78%). Treatment of neck lesions was either by neck dissection (85.2%) or “wait and see” (14.8%). The rates for local and nodal recurrence were 7.9% and 20.4%, respectively. Analysis of associations between DFS and different factors revealed significance for adoption of adjuvant therapy and the dissected lymph node status. Conclusion: Controversy still exists regarding neck management.
