Value of minimal residual disease in patients with early cancer of the tongue.

Purpose: The clinical course of patients with squamous cell carcinoma (SCC) of the tongue is often unpredictable. Some patients have a fair course with good response to treatment, whereas others have aggressive locoregional disease despite diagnosis at an early stage. The purpose of the present study was to determine if histochemical staining for cytokeratins of the negative neck nodes obtained in prophylactic neck dissection could predict treatment failure in patients with SCC of the tongue.

Expression of EGFR and Cerb-B2 as prognostic factors in cancer of the tongue.

Squamous cell carcinoma (SCC) of the tongue is sometimes associated with local recurrence and regional metastases despite adequate surgical excision. The present study sought to determine if epidermal growth factor receptor (EGFR) and Cerb-B2 expression has prognostic or predictive value in SCC of the tongue, as with other epithelial malignancies. The study sample comprised of 27 patients with carcinoma of the tongue who underwent partial glossectomy and neck dissection between 1990 and 1999.
