Background

The indicating FTA card is a dry medium used for collection of cervical samples. HPVIR is a multiplex real-time PCR test that detects 12 high-risk human papillomavirus types (hrHPV) and provides single genotype information for HPV16, − 31, − 35, − 39, − 51, − 56, and − 59 and pooled type information for HPV18/45 and HPV33/52/58. The aim of this study was to evaluate whether a strategy with cervical samples collected on the FTA card and subsequently analysed with the HPVIR test complies with the criteria of the international guidelines for a clinically validated method for cervical screening.

Methods

We performed a non-inferiority test comparing the clinical sensitivity and specificity of the candidate test (FTA card and HPVIR) with a clinically validated reference test (Cobas® HPV test) based on liquid-based cytology (LBC) samples. Two clinical samples (LBC and FTA) were collected from 896 participants in population-based screening. For evaluation of the specificity we used 799 women without ≥ CIN2, and for clinical sensitivity we used 67 women with histologically confirmed ≥ CIN2. The reproducibility was studied by performing inter- and intra-laboratory tests of 558 additional clinical samples.

Results

The clinical sensitivity and specificity for samples collected on the FTA card and analysed using the HPVIR test were non-inferior to samples analysed with the Cobas® HPV test based on LBC samples (non-inferiority test score, p = 1.0 × 10− 2 and p = 1.89 × 10− 9, respectively). Adequate agreement of > 87% was seen in both the intra- and inter-laboratory comparisons.

Conclusions

Samples collected on the indicating FTA card and analysed with HPVIR test fulfil the requirements of the international guidelines and can therefore be used in primary cervical cancer screening.

Abstract [en]

We conducted a randomised study to compare vaginal self-sampling with assisted sampling by medical personnel on the cervix for HPV testing in primary screening. The first aim was to determine if the HPV prevalence is independent of sampling location (vagina versus cervix) and the person performing the sampling. The second aim was to evaluate if the two sampling strategies differed in the detection rate of CIN2+. In total, 19,523 women were randomised into two groups, with 9926 invited to perform self-sampling (SS arm) using the Rover VIBA-brush and 9597 offered assisted sampling using the cytobrush (AS arm). All samples were applied to the indicating FTA elute card and analysed for high-risk HPV using the hpVIR real-time PCR assay. The outcome for the first aim was HPV prevalence and for the second aim the number of CIN2+ based on histology. In the SS arm, 52.7% of invited women participated in the study, as compared to 34.2% in the AS arm. All samples contained sufficient amount of nuclear DNA for a valid HPV result, with vaginal samples having a higher DNA amount than cervical samples (p < 4.62 × 10-11 ). HPV prevalence was 4.6% in the SS arm and 4.1% in the AS arm (p = 5.5 × 10-2 ), and the distribution of HPV types similar between arms. There was no difference in the prevalence of CIN2+ per 1000 women screened between arms (p = 0.86). The results show that vaginal self-sampling is an equivalent alternative to sampling by medical personnel for HPV typing and identification of CIN2+.

Abstract [en]

Background:

This randomised study compared the detection rate of cervical intraepithelial neoplasia-positive (CIN2+) based on histology in women performing repeated self-sampling of vaginal fluid (VF) for human papillomavirus (HPV) test with a control group following the ordinary screening by Pap smear cytology.

Methods:

36390 women aged 30–49 years scheduled for invitation to organised screening were randomised in two groups, one to perform self-sampling of VF for HPV test (n=17 997, HPV arm) and the other group to perform screening by PAP smear cytology (n=18 393, control arm). HPV positive women in the HPV arm repeated the self-sampling and the HPV test on average 4.4 months later and those with two consecutive positive HPV tests were referred to colposcopy. Outcome was CIN2+ based on histology during 18-month follow-up.

Results:

Participation rate was 47% in the HPV arm and 39% in the control arm. The HPV prevalence in the first self-sampling was 6.9%, and 71% of these women were HPV positive in their second test. For the per-protocol approach, cumulative prevalence of histological CIN2+ in the HPV arm was 20.2 per 1000 women screened as compared to 10.8 in the control arm. The cumulative prevalence of CIN2+ diagnosed per 1000 years screened was 160.8 in the HPV arm as compared with 25.4 in the control arm.

Conclusions:

Repeated self-sampling of VF and HPV test had more than a two-fold higher discovery rate of CIN2+ per 1000 women screened as compared with PAP smear cytology.

Abstract [en]

The minimally invasive tension-free vaginal tape (TVT) operation has become the "gold standard" of incontinence surgery. The aim of the present study was to evaluate the long-term effect of the tape material and to assess the continence status 17 years after surgery A cohort of 90 women operated upon with the TVT procedure at three Nordic centers has been prospectively followed for 17 years. All of the women alive according to national registries were contacted and invited to visit the clinics for evaluation. Pelvic examination was performed to reveal any adverse effects of the tape material. Objective and subjective continence status were assessed by a cough stress test and the patients' global impression of improvement as well as by condition-specific quality of life questionnaires. Seventy-eight percent of the potentially assessable women were evaluated either by a clinic visit or by a telephone interview. One case of a minimal, symptom-free tape extrusion was seen. No other tape complications occurred. Over 90 % of the women were objectively continent. Eighty-seven per cent were subjectively cured or significantly improved. The TVT operation is durable for 17 years, with a high satisfaction rate and no serious long-term tape-induced adverse effects.
