SOCS1 and hypopharyngeal carcinoma: Hypopharyngeal carcinoma tissues had lower level expression of SOCS-1 and SOCS-3 than pericarcinoma tissues, but there was no significant difference, while cancer tissues had significantly higher level expression of NF-κB p65 than that of pericarcinoma tissues (0.412±0.266, 0.281±0.231, t=2.969, P=0.004).
