Twelve nonpathologists of varying educational backgrounds living in Beijing, China received video training and were assigned one of 4 sets of 25 CIN2+ and 25 CIN less severe than CIN2 for evaluation.

p16INK4A immunohistochemical staining and predictive value for progression of cervical intraepithelial neoplasia grade 1: a prospective study in China.

p16(INK4A) is strongly expressed in tissues diagnosed as cervical intraepithelial neoplasia (CIN) and cancer in women infected with human papillomavirus (HPV), but few prospective studies have evaluated p16(INK4A) as a marker for the risk of low-grade CIN (CIN1) progression. We investigated the prevalence of p16(INK4A) immunostaining by CIN grade and whether overexpression of p16(INK4A) in CIN1 predicts future risk for high-grade CIN in Chinese women. 6,557 Chinese women aged 30-49 years were screened from 2003 to 2005 using cytology and carcinogenic HPV test.
