[Histological diagnosis of squamous cell carcinomas of oral cavity and pharynx origin - prognostic and predictive factors].

Abstract

Squamous cell carcinoma is the most prevalent tumor type among the malignancies of the mucosal lined surfaces in the head and neck region. Most frequently the diagnosis is based on the tissue taken from the primary tumor and in some cases an involved lymph node serves as a source of samples. The pathology report plays a crucial role in the decision making which is guided by the different factors included in the report. In this article we aimed to summarize the prognostic and predictive factors regarding squamous cell carcinoma of oral and pharyngeal origin while taking into account the international standards.
