Patient choice may improve adherence to follow-up in cervical screening: a randomised-control trial.

AIMS: We investigated whether patient choice of follow-up type improves health-related quality of life (HrQOL) and follow-up attendance in women who have undergone large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia grade 2 to 3 (CIN 2-3). METHODS: A three-armed randomised controlled trial including women with newly diagnosed CIN 2-3 post-LLETZ treatment was performed. Consenting women were randomised (1:1:1) to either: (a) colposcopy review at the hospital, (b) follow-up with high-risk human papilloma virus (HrHPV) and smear test in the community or (c) a choice of the aforementioned follow-up options, six months post-treatment. HrQOL was measured and participants were surveyed at baseline and six months regarding preferences for follow-up. RESULTS: Sixty-eight participants were randomised to follow-up (a), 67 to follow-up (b) and 65 to follow-up (c) (n=200). At six months post-treatment, 47% of patients indicated a preference for (a), 24% for (b) and 26% for (c). We found no significant difference in HrQOL between the study arms. Attendance was greater among patients who chose their follow-up (95.5% vs 91.1%, p=0.06). CONCLUSION: Choice of follow-up was associated with greater attendance. However, larger studies examining the effects of HrQOL and attendance to different follow-ups are warranted.

Trends in the diagnosis of high-grade cervical abnormalities in young women in the post-vaccination era.

BACKGROUND: Most cervical cancers are associated with human papillomavirus (HPV) types 16 and 18. In 2008, New Zealand commenced a quadrivalent HPV (virus-like particles of types 6, 11, 16 and 18) vaccination programme. AIM: Document trends in number of colposcopy referrals and number and grade of cervical abnormalities diagnosed in women (20-24 years) referred to three large colposcopy clinics over time. METHOD: Retrospective analysis of colposcopy clinic data. RESULTS: The dataset included 5,012 episodes from 4,682 women. In Auckland (2013-2017), there was a 38% decrease in colposcopy referrals and 55% decrease in cervical intraepithelial neoplasia grade 2 (CIN2) or worse diagnoses. In Waikato (2011-2017), there was an 8% decrease in referrals and 22% reduction in CIN2 or worse diagnoses. In Canterbury (2011-2017), there was a 24% decrease in referrals and 49% reduction in CIN2 or worse diagnoses. Across all centres, the decrease in cervical intraepithelial neoplasia grade 3 (CIN3) or worse diagnoses was marked and more consistent than in CIN2 diagnoses. However, while the proportion of biopsies reported as CIN3 or worse decreased in non-Maori (24% in 2013 vs 16% in 2017, nptrend z=-4.24, p>|z| <.001), there was no change in Maori women (31% in 2013 vs 29% in 2017, nptrend z=-0.12, p>|z| =.90). CONCLUSIONS: We observed a decreased number of CIN diagnoses in young women over time, with a particularly large drop in the number of CIN3/AIS/CGIN diagnoses. However, compared to non-Maori, Maori women having biopsies are more likely to have CIN3 or worse and there was a smaller reduction in the total number of Maori women diagnosed with CIN2 or worse.

Initial observation of CIN2 does not appear to reduce quality of life in women under 25 years of age.

BACKGROUND: Although the patient perspective is implicit in the practice of medicine, research evaluating this remains scarce. In a climate where clinicians and policy-makers constantly strive to achieve more patient-centred models of care, this omission warrants attention. AIM: To assess health-related quality of life (HrQoL) in women under 25 years of age with cervical intra-epithelial neoplasia grade 2 (CIN2) receiving conservative management (colposcopy follow-up, with treatment if necessary) compared with those receiving immediate excisional treatment with large loop excision of the transformation zone (LLETZ). METHODS: An observational study evaluating HrQoL was conducted at Christchurch Women's Hospital, New Zealand. Women undergoing conservative management for CIN2 were compared with those undergoing immediate excisional treatment in an age-matched sample. The Short Form Health Survey 12 version 2 (SF-12v2) was used to evaluate HrQoL. Secondary outcomes of anxiety and sexual function were also assessed. RESULTS: One hundred and four women with CIN2 participated in the study. Of these, 63 (60%) received conservative management and 41 (40%) received immediate excisional treatment with LLETZ. We found no significant difference in HrQoL between the groups in a multivariate regression analysis adjusted for parity, smoking and socioeconomic status. There were also no significant differences in sexual function or anxiety. CONCLUSION: We found no difference in HrQoL by management strategy. Conservative management of CIN2 in women under 25 is unlikely to have an adverse impact on self-reported HrQoL, anxiety or sexual functioning compared with conventional management.

Is the treatment of CIN 2 always necessary in women under 25 years old?

OBJECTIVE: The purpose of this study was to review the outcome of conservatively managed cervical intraepithelial neoplasia (CIN) 2 in women <25 years old. STUDY DESIGN: This was a retrospective review that included women who were <25 years old with biopsy proven CIN2 between 2005 and 2009. Analysis was performed that compared women who had immediate treatment with women whose treatment was deferred >4 months. The primary outcome measure was spontaneous regression of CIN2. Secondary outcomes were treatment rates and loss to follow-up evaluation. RESULTS: Of the 452 women who were identified, 256 women (57%) received immediate treatment; 157 women (35%) met the definition for conservative management, and 39 women (9%) had unknown subsequent management. Of the 157 women who were managed conservatively, 98 women (62%) showed spontaneous regression, with a median of 8 months observation. No conservatively managed women progressed to cancer. CONCLUSION: Based on the 62% regression rate in this study, routine treatment may not be necessary for all women with CIN2 who are <25 years old.

Testing for high risk human papilloma virus in the initial follow-up of women treated for high-grade squamous intraepithelial lesions.

BACKGROUND: The follow-up schedule of women who have undergone treatment for high grade squamous intraepithelial lesions (HSIL) is a crucial part of the cervical screening programme. The ability to detect residual disease or early recurrence enables the provision of timely secondary intervention. AIMS: The aim of this study was to determine the prevalence of High Risk HPV and cytological abnormalities at first follow-up visit post treatment. The feasibility, safety and cost benefit of omitting routine colposcopy as a first line investigation were evaluated. METHODS: A total of 100 women with histologically confirmed and treated HSIL were recruited prior to first follow-up visit. Colposcopic assessment, cervical cytology using LBC and HR HPV testing was carried out on all women. RESULTS: In all, 75% of the study group had both a negative HR HPV test and a normal cervical cytology at first follow-up visit. Mean time interval to first follow-up was 9 months. The rate of residual/recurrent high-grade disease within this cohort was 4% followed up to 18 months post treatment. HR HPV had a sensitivity of 100% to detect persistent HSIL. CONCLUSION: High-risk human papilloma virus testing in combination with cytology at first follow-up visit in women treated for HSIL has a very high sensitivity and negative predictive value. Colposcopy does not improve specificity in this cohort and could be omitted in patients who have a negative smear and HPV test.
