See and Treat in an Outpatient Setting in Women Above 45 Years With Cervical Dysplasia

The study will investigate if implementation of "see and treat" in the outpatient clinic can optimize the diagnosis, clinical follow-up and treatment of older women with positive cervical screening test.

In Denmark, 370 women are diagnosed with cervical cancer every year and approximately 100 women die from the disease. Young women can be protected with the HPV vaccine, but it will take decades before the vaccine has an effect on older women. Women who are HPV positive have a risk of developing severe dysplasia of 25-55% within 10 years. Compared to younger women, older women are also more likely to be diagnosed with advanced-stage disease and their mortality is high. Due to retraction of the transformation zone into the cervical canal and atrophy of the mucosa the performance of colposcopy is low. Furthermore, the sensitivity of cytology decreases with age. This makes it very difficult to obtain sufficient biopsies and therefore postmenopausal women are often required to undergo colposcopy two to three times. Waiting for a final diagnosis and treatment not only has a large mental and practical impact on the women themselves, but it is also an economic burden for the health care system. "See and treat" is a procedure that involves cervical cytology and HPV test, a colposcopy, cervical biopsies, and finally a loop electrosurgical excisional procedure by which the transformation zone is removed. This approach allows women to be diagnosed and treated in one visit. In this project, the aim is to investigate if the implementation of "see and treat" in a gynecological outpatient clinic can optimize the diagnostics, clinical follow-up, and treatment of older women with abnormal cervical cytology or HPV-infection. Participants Women aged ≥ 45 years with cervical dysplasia and/or a positive HPV test are referred from the general practitioner to the gynecological department. Procedure At each inclusion site, the local project manager evaluates all the referred women for possible inclusion. Project information is sent either by e-mail or letter to eligible women. At the outpatient clinic, the eligible women will be informed about the project and asked to sign an informed consent form regarding their participation in the project. If the eligible women agree to participate a physician in the outpatient clinic will obtain a cervical smear (i.e. cytology and Human Papillomavirus (HPV) test) and perform colposcopy and take four random biopsies. If the transformation zone (TZ) is partly visible or not visible a cone biopsy will be performed in local anesthesia (Citanest). If the participant meet the exclusion criteria or declines to participate standard treatment will be offered (colposcopy and biopsies). The included patients will be followed up with an HPV test after 6 months.

Cone biopsi is offered to women age ≥ 45 years referred to Department of Obstetrics and Gynecology due to a positive cervical screening test and partly or invisible transformation zone.

The histological diagnose from the Pathological Department will be available 8 weeks after inclusion.
