Prognostic significance of high-risk human papillomavirus and p16(INK4A) in patients with esophageal squamous cell carcinoma.

Prognostic significance of high-risk human papillomavirus and p16(INK4A) in patients with esophageal squamous cell carcinoma. Int J Clin Exp Med. 2014;7(10):3430-3438 Authors: Cao F, Zhang W, Zhang F, Han H, Xu J, Cheng Y Abstract The prognostic value of the HPV status in ESCC is much controversial, this study aimed to determine the prognostic importance of high-risk HPV and p16 in patients with ESCC. A total of 105 consecutive patients who underwent esophagectomy in 2008 were included in this study. All specimens with ESCC were tested by in situ hybridization for HPV16/18 and immunohistochemistry for p16 expression. Kappa values were calculated using Cohen's kappa test. The 5-year overall survival (OS) and progression-free survival (PFS) were calculated in relation to the two markers and the Cox proportional hazards model was used to determine the hazard ratio (HR) of variables. Thirty-nine (37.1%) of 105 were p16-positive, and HPV was detected in 29 of the 105 patients (27.6%) with ESCC. P16 was detected in 25 of the 29 patients (86.2%) who were HPV-positive, and only 14 of 76 patients (18.4%) who were HPV-negative (P < 0.001). Cohen's kappa coefficient revealed an agreement in two researchers (kappa = 0.61). The 5-year OS rate and PFS rate in the p16-positive group were 64.1% and 58.7%, respectively, and the rates in the p16-negative group were 45.5%, 37.9%, respectively. The difference of survival rate between the two groups r...
