HPV 16 in multiple neoplastic lesions in women with CIN III.

Author information

University of Oslo, Norway.


Paraffin embedded material of multiple primary cancers and other hyperplastic tumours from fifteen patients were analyzed by PCR and in situ hybridization for the presence of HPV DNA in the lesions. All patients had also high grade cervical intraepithelial dysplasia (CIN III) and breast carcinomas and were selected from a previous study enrolling 46 women with CIN III and breast carcinomas. HPV 16 was detected by PCR in 8/15 patients (53%), with eleven HPV 16 positive tumours. HPV 16 was detected in two malignant melanomas, one basal cell carcinoma, one squamous cell carcinoma of the vulva, one Bowen disease of the vulva, two high grade vaginal intraepithelial neoplasias, one cancer corporis uteri, one bronchial carcinoma and two lymphomas. Three cases, two high grade vaginal intraepithelial neoplasia and a squamous cell carcinoma of the vulva, were also reported to be positive by in situ hybridization. 5/8 patients (63%) with HPV 16 positive second cancers had also HPV 16 positive breast carcinomas. All fifteen patients with second cancers after CIN III had HPV 16 positive CIN III lesions; 53% of the patients had also a familial cancer history. We assume that HPV 16 may be involved in the development of different second cancers in women with HPV 16 positive CIN III.
