Treatment results and prognostic factors for advanced squamous cell carcinoma of the head and neck treated with concurrent chemoradiotherapy

In the treatment of CCR for advanced SCCHN, the survival rate of the patients with resectable tumors was excellent and significantly greater compared with the patients with unresectable tumors. T1 to T3 disease in patients with advanced resectable SCCHN is a good predictor of organ preservation. CCR may improve not only primary organ preservation (local control) but also survival in patients with poorly differentiated tumors.
