Abstract
Objective: To study human papillomavirus type 16 in the aetiology of cervical carcinoma.
Design: Within a cohort of 18814 Finnish women followed for up to 23 years a nested case-control study was conducted based on serological diagnosis of past infection with human papillomavirus type 16.
Subjects: 72 women (27 with invasive carcinoma and 45 with in situ carcinoma) and 143 matched controls were identified during the follow up.
Main outcome measure: Relative risk of cervical carcinoma in presence of IgG antibodies to human papillomavirus type 16.
Results: After adjustment for smoking and for antibodies to various other agents of sexually transmitted disease, such as herpes simplex virus type 2 and Chlamydia trachomatis, the only significant association was with infection with human papillomavirus type 16 (odds ratio 12.5; 95% confidence interval 2.7 to 57, 2P<0.001).
Conclusion: This prospective study provides epidemiological evidence that infection with human papillomavirus type 16 confers an excess risk for subsequent development of cervical carcinoma.

Human papillomavirus type 16 is the main micro-organism linked to the development of cervical cancer
Prospective studies of infection with this virus and cervical cancer have not been reported because of ethical and clinical difficulties and because diagnosis of past infections with the virus has not been possible
In this nested case-control study in over 18000 Finnish women who donated blood to a serum bank 25 years ago we were able to measure past infection with human papillomavirus type 16 with new serological tools
The results show that infection with the virus confers an increased risk of developing cervical cancer
