Human papillomavirus (HPV) type 16 DNA is frequent in invasive cervical cancers. Among 43 patients with invasive cervical cancer, HPV-16-positive tumors spread to the parametrial and pelvic lymph nodes significantly more often than did HPV-16-negative tumors ( P < 0.05). Demonstration of HPV-16 DNA

Abstract
A substantial increase in the incidence of severely dysplastic cervical lesions (CIN 3) has been observed during the period 1975โ1982 in the East Anglian region of England. Since patients with severe dysplasia have an enhanced risk of developing cervical carcinoma, it seems possible that a substantial increase in the rate of cervical carcinoma is likely to occur in the near future. Evidence of a relationship between human papillomavirus (HPV) infection and cervical carcinoma has accumulated recently. We have studied the incidence of HPV 16 DNA in cervial tissue samples from patients with cervical carcinoma, severe dysplasias and normal controls. Five out of II invasive squamous carcinomas of the cervix, 3/4 dysplasias and 0/12 normal samples were positive in Southern blot assays for HPV 16 DNA. Some of the tissue samples had as many as 500 copies of HPV 16 DNA per cell. The amount of HPV 16 DNA present correlated with the aggressiveness of tumour growth.
