Human papillomavirus (HPV) is known to be an important etiopathogenetic factor in intraepithelial neoplasia and invasive squamous cell carcinomas of the cervix. We detected HPV DNA occurrence and subtypes in 18 intraepithelial neoplasia and 14 squamous cell carcinomas of the cervix by in situ hybridisation technique. We revealed a statistically significant difference for the HPV DNA occurrence between intraepitelial neoplasias and carcinomas (p<0.05). While we could not demonstrate any statistically significant correlation between intraepitelial neoplasias and carcinomas for the HPV subtype 6/11, we found a statistically significant correlation between intraepitelial neoplasia and carcinomas with HPV subtype 16/18 (p<0.04).
