Moreover, as demonstrated in Table 4, the PRB4 level (P=0.027), NSD1 level (P=0.018), tumor size (P=0.030), metastasis (P=0.012) and clinical stage (P=0.021) were found to be independent factors for predicating the prognosis of hypopharyngeal cancer patients. This evidence concerns the gene NSD1 and hypopharynx cancer.
