Plain English Summary

Background and study aims
Cervical cancer is diagnosed in 470,000 women a year worldwide and 273,000 women die of the disease, mostly where there is less helpaccess to healthcare. If detected early, many women can be cured of the disease. However, often women lack access to screening, diagnosis and treatment. Our aim is to compare the performance of a battery-driven colposcope, the Gynocular, to traditional stationary colposcopes in detecting the cervical cancer lesions.

Who can participate?
Women referred to undergo colposcopy to detect cervical lesions can take part in this study.

What does the study involve?
Women are randomly allocated to undergo examination using either the Gynocular or the traditional colposcope. A sample from the cervix is taken from all women for further analysis. The performance of the two instruments are is analysed.

What are the possible benefits and risks of participating?
There are no risks to the women in participating in the study.

Where is the study run from?
1. Department of Obstetrics and Gynecology, Danderyd Hospital, Sweden
2. Department of Clinical Sciences, Karolinska Institute (Karolinska Institutet), Stockholm, Sweden.

When is the study starting and how long is it expected to run for?
The study ran from June 2012 to July 2013.

Who is funding the study?
The H&M Conscious Concious Foundation (Sweden) and Gynius AB (Sweden) funded the study.

Who is the main contact?

Study information

Scientific title

A comparison of the performance of the Gynocolar and stationary colposcope by the Swede score colposcopy system in women with abnormal cytology: a randomized cross-over trial



Study hypothesis

A pocket-sized mini-colposcope magnifier (Gynocular) is equally good at detecting cervical lesions compared to a stationary colposcope.

Primary study aim: to demonstrate that the Gynocular magnifier is non-inferior to a stationary colposcope in finding acetowhite cervical lesions during examination in women with precancerous cervical dysplasia.

Secondary study aim: to show that the Gynocular magnifier is non-inferior to a colposcope with regard to sensitivity and specificity in finding cervical intraepithelical neoplasia (CIN) verified in cervical biopsies.

Colposcopy and cervical dysplasia


Women will be randomly allocated in blocks of clinic day to start the examination with either the stationary colposcope or the Gynocular. Then, the woman will be examined by the same examiner with the second instrument in order to assess the performance of agreement between the two instruments.

Primary outcome measure

Each patient will be assessed by the Swede score systematic colposcopy system, where each of five colposcopic variables (acetowhiteness, margins plus surface, vessel pattern, lesion size and iodine staining) are given a score of 0, 1 or 2 points. All women will also have a liquid-based cytology specimen taken at the time of examination using a plastic spatula on the cervix and a cervix brush in the cervical canal. The examination will be finalized with one or more biopsies taken from areas of suspected cervical lesions when the Swede score is above 0.
