The presence of high-risk HPV combined with specific p53 and p16INK4a expression patterns points to high-risk HPV as the main causative agent for adenocarcinoma in situ and adenocarcinoma of the cervix.

0.001). Immunostaining for p53, pointing to stabilized wild-type or mutant p53 protein, was significantly more frequent in hrHPV cervical AdCAs negative for hrHPV (p=0.01). No difference in p16INK4a and p53 immunostaining was found between hrHPV-negative cervical AdCAs and endometrial AdCAs. Hence, only a minority of cervical AdCAs displayed absence of HPV DNA and immunostaining profiles suggestive of an aetiology independent of HPV. Since all ACISs and nearly all cervical AdCAs were hrHPV-positive, the incorporation of hrHPV testing in cervical cancer screening programmes is likely to decrease markedly the incidence of cervical AdCA.
