This retrospective case control study was conducted to assess the prognostic value of some patient-, tumor-, treatment-related variables, and to correlate markers of primary tumor with survival and cervical metastases. Twenty-five patients with histologically proven squamous cell carcinoma of the oral cavity and oropharynx were analyzed. Patients were never treated before and had a minimum follow-up review of 45 months. Results show that T-stage is the most important clinical prognostic parameter. Regarding immunohistochemical markers (Ki67 and CD44), only CD44 seems to be significantly correlated with prognosis but this value showed a multicollinear effect with N upon survival. Decreased expression of CD44 correlates with a decreased survival, although increased CD44 expression was consistent with a longer survival. Therefore, it was assessed that a loss of cell adhesion, related to decreased expression of CD44, may be determinant of survival in these patients.

Abstract

This retrospective case control study was conducted to assess the prognostic value of some patient-, tumor-, treatment-related variables, and to correlate markers of primary tumor with survival and cervical metastases. Twenty-five patients with histologically proven squamous cell carcinoma of the oral cavity and oropharynx were analyzed. Patients were never treated before and had a minimum follow-up review of 45 months. Results show that T-stage is the most important clinical prognostic parameter. Regarding immunohistochemical markers (Ki67 and CD44), only CD44 seems to be significantly correlated with prognosis but this value showed a multicollinear effect with N upon survival. Decreased expression of CD44 correlates with a decreased survival, although increased CD44 expression was consistent with a longer survival. Therefore, it was assessed that a loss of cell adhesion, related to decreased expression of CD44, may be determinant of survival in these patients.
