Cervical intraepithelial neoplasia (CIN), Digital colposcopy, Human papillomavirus

Intervention(s)
1. Besides conventional colposcopy, colposcopy with DySIS.

2. hrHPV, viral load, E6/E7 antibodies and p16INK4a testing.

3. At random biopsy.

4. Measurement of the lesion size.
Primary Outcome(s)
Primary endpoint:

Consensus in DySIS colposcopic and conventional colposcopic impression of a lesion and histology (?golden standard?).
Secondary Outcome(s)
Secondary endpoints:

1. Consensus in DySIS colposcopic and conventional colposcopic localization of the optimal biopsy point and histology (?golden standard?).

2. Consensus of DySIS colposcopic and conventional colposcopic impression of a lesion and HPV GP5+/6+ PCR testing and hybrid capture.

3. Higher HPV viral load by a larger, hrHPV positive, lesion (through (semi-)quantitative, real-time PCR-based viral load assessment).

4. A relation between p16INK4a and the size of the lesion.

5. A relation between viral load and hrHPV antibody titers.
