Prognostic significance of p53 codon72 polymorphism, p503 mutations. human papillomavirus, and pretreatment PET parameters, in addition to clinical factors, were prospectively addressed in patients with locoreginally advanced head and neck sqamous cell carcinoma treated by concurrent chemoradiotherapy. Pretreatment PET parameters include SUVmax. SUVmean, and metabolic tumor volume of a primary tumor. Multivariatc analysis revealed that MTV is only an independent prognostic factor. Overall survival as well as laryngectomy survival were significantly better in patients with low MTV tumor than in those with high MTV tumor.
