HCP5 and nasopharyngeal carcinoma: Tse KP et al. (Tse et al. 2011) analyzed the cervical nodal volume (CNV) in patients with nasopharyngeal carcinoma and found that 8 CNV regions in patients with nasopharyngeal carcinoma were significantly changed compared with those in the normal population and that single copy deletion of HCP5 occurred in the stained 6p21.3 region and was significantly related to the occurrence of nasopharyngeal carcinoma.
