Conditions
Brief summary
This is a register-based, epidemiological study of HPV type distribution in women aged 18 years and above with recurrent conization following a primary conization for high grade lesions/ microinvasive carcinomas. This study will involve data collection from different databases in the Cancer Registry of Norway.
Detailed description
This protocol posting has been updated following Protocol Amendment 1 (02 April 2010). The sections impacted are: enrolment, outcome measures and eligibility criteria.
Interventions
Review of database to identify women with primary conization presenting with high grade lesions/ microinvasive cervical carcinomas. Recurrent cones with high grade lesions/ microinvasive cervical carcinomas or invasive cervical cancer will be identified for all women with primary cones.

Eligibility
Inclusion criteria
All subjects must meet the following criteria at study entry: * Women aged 18 years and above at the time of the collection of the primary cone specimen; * Who have undergone for the first time a conization due to high grade lesions or microinvasive cervical carcinomas, histologically diagnosed in 2003, with possible extension backwards in time; * Availability of recurrent cone specimen with high grade lesions/ microinvasive cervical carcinomas or invasive cervical cancer; * Availability in designated local laboratories of the primary and recurrent cone specimens; * The cone specimen was adequately preserved; * Written informed consent obtained from the subject. If the subject is deceased, the cone and biopsy specimens will be used according to prior approval from the Ethics Committee.
Exclusion criteria
None.
