TP53 mutations and S-Phase fraction are independent prognostic indicators in locally advanced laryngeal squamous cell carcinoma

2005

Larynx tumor is a rare neoplasia that represent only the 2% of all human tumor. In particular, the 90% of tumor that occur in this organ correspond to the laryngeal squamous cell carcinoma (LSCC). From the biomolecular point of view, it was shown that the TP53 gene mutations are the most common events observed in the early phases of LSCC carcinogenesis. However, them prognostic significance remains controversial. Besides, the prognostic significance of DNA ploidy has been well established for other solid tumors, but its role in LSCC is still controversial. The aim of this study was, therefore, to prospectively evaluate the prognostic significance of TP53 mutations, DNA-ploidy and S-phase fr…
