ABSTRACT
BACKGROUND: The aim of this study is to determine the need for a randomized controlled trial in order to define the role of an elective neck dissection (END) in the treatment of early tongue cancers. METHODS: We present a large retrospective analysis of patients with T1-2 N0 squamous cell cancers of the oral anterior tongue treated at a single institution. A total of 359 eligible patients with early tongue cancers were divided into 2 groups: END and wait and watch (WW). An analysis for survival outcomes and prognostic factors was conducted. RESULTS: The estimated 3- and 5-year disease-free survival for the END group was 76% and 74% versus 71% and 68% for the WW group, respectively (p = .53). The 3- and 5-year overall survival (OS) rate for the END group was 69% and 60% versus 62% and 60% for the WW group, respectively (p = .24). Tumor grade and perineural invasion were independent predictors of recurrence. CONCLUSION: END did not impact disease-free or OS. Current literature still remains divided on this issue emphasizing the need for a randomized controlled trial.

Localized amyloidosis is characterized by the deposition of amyloid fibres in a particular site or organ system in the absence of systemic involvement. Patients with localized laryngeal amyloidosis usually present with long-standing hoarseness or dyspnea. The diagnosis is made by a high degree of suspicion on the basis of the history and a characteristic appearance on direct laryngoscopic examination. When such lesions are seen, an adequate deep punch biopsy should be obtained, and an experienced pathologist should be able to identify the lesion on routine staining. However, the slides should be stained with Congo red and examined with polarized light microscopy to establish the diagnosis. Following proper diagnosis and evaluation of the extent of disease, usually by computed tomographic scan, surgery is the treatment of choice. Preservation of the voice and airway should be the aim in all patients. Endoscopic carbon-dioxide laser excision of the mass should be the first line of therapy. Patients may require repeated removal of the amyloid deposits. The results of treatment are excellent.
