Aims: To assess colposcopic performance and determine indicators for competency within the new Australian primary human papillomavirus (HPV) cervical screening program. Materials and methods: A retrospective observational study of 4542 women seen at The Royal Women's Hospital Colposcopy Clinic in Melbourne, from 1 December 2017 to 31 July 2020 after a higher‐risk cervical screening test (CST) result. Results: Histological CIN2+ was detected in 25.1% up to two years from first colposcopy visit (FCV). The majority (86.7%) of CIN2+ was detected early within the first six months of presentation. Biopsy rate overall was 96.1% with abnormal colposcopic impression. Of four colposcopists with a lower biopsy rate, only one was able to achieve this early detection rate. Biopsy was also taken in over 30% of cases with negative reflex cytology and normal colposcopy, with CIN2+ detected in 5.0% among positive HPV16/18 and 3.8% with non‐16/18 HPV. Positive predictive value of high‐grade colposcopic impression at FCV averaged 66.4% (range: 54.9–81.6% among our colposcopists) and is poorly correlated with early detection rate of CIN2+. Overall accuracy of colposcopy is 84.5% (range: 78.7–90.3%), buoyed by high true negative colposcopic predictions secondary to high rates of negative reflex cytology referral with the new screening algorithm and is also unlikely to be a useful colposcopy indicator. Conclusions: Early detection rate of CIN2+ within the first six months of presentation is a useful measure of colposcopy competency and we would encourage our National Cancer Screening Register to explore this with the participating colposcopists.

Background: Adenocarcinoma in situ of cervix is increasingly managed by local excision rather than hysterectomy and this study will ascertain if conservative management by excision alone is adequate. Aims: To evaluate the long‐term outcomes of conservative management of adenocarcinoma in situ of cervix, particularly in relation to excisional margin status. Materials and Methods: Retrospective analysis of women diagnosed with adenocarcinoma in situ and their management between 1992 and 2010 retrieved from the Victorian Cervical Cytology Registry, Australia. Failure of conservative treatment is defined by histologically proven adenocarcinoma in situ or adenocarcinoma at follow‐up after negative excisional margins. Results: adenocarcinoma in situ of the cervix was managed primarily with cold knife cone biopsy or loop electrosurgical excision of the cervix. Most excisions were in one piece (83.4%) with average depth of 16.1 mm and 21.9% had involved excisional margins. Women with adenocarcinoma in situ on any excisional margin were more likely to have residual or recurrent disease (28.7%) compared with negative excisional margins (4.3%). Residual adenocarcinoma in situ was twice as common if adenocarcinoma in situ was present at endocervical (29.6%) and stromal (23.1%) margins compared with an ectocervical margin (13.6%). Cancer incidence at follow‐up was 2.3% for women with positive excisional margins compared to 1.3% with negative margins. Conclusions: Women with adenocarcinoma in situ of cervix can be managed with local excisional procedures, best in single pieces to provide the important information on excisional margins. Adenocarcinoma in situ at endocervical and stromal excisional margins needs re‐excision or where appropriate, hysterectomy, while negative excisional margins have a low rate of recurrence and can be followed up with test of cure.
