A Mail-Based HPV Self-Collection Program to Increase Cervical Cancer Screening in Appalachia: Results of a Group Randomized Trial.

Background: Despite the promise of mail-based human papillomavirus (HPV) self-collection programs for increasing cervical cancer screening, few have been evaluated in the United States. We report the results of a mail-based HPV self-collection program for underscreened women living in Appalachia.

Methods: We conducted a group randomized trial during 2021-2022 in the Appalachian regions of Kentucky, Ohio, Virginia, and West Virgnia.

AmpFire HPV and ScreenFire RS HPV validation trial.

Objectives: The human papillomavirus (HPV) screening assays from Atila Biosystems, including the new AmpFire (14 type) and ScreenFire RS (13 type), were subjected to a series of validation tests.

Objective: To assess the prevalence and distribution of HPV genotypes among Chinese Han women, and to explore the risk of high-grade cervical lesions associated with individual hr-HPV genotypes.

Methods: Genotyping and histopathology data from the Chinese Multi-Center Screening Trial (CHIMUST) and its pilot screening trial, from 6 regions across mainland China, were re-analyzed. The data from physician- and self-collected samples from 10,867 Chinese Han women (ages 30-69) were used to determine the prevalence and distribution of hr-HPV and to explore the risk association between hr-HPV genotypes and precancerous lesions.

Objective: The aim of the study was to evaluate the Cobas 4800 Assay and the SeqHPV Assay with self (S) and direct (D) cervical samples in the Chinese Multicenter Screening Trial (CHIMUST).

Materials And Methods: The CHIMUST is a large population-based multicenter clinical trial, and 10,885 women aged 30-59 years from 15 sites in 7 provinces with no cervical cancer screening for 3 years were eligible. All participating women contributed one self-collected sample (S) and 1 physician-collected endocervical sample (DL).

An evaluation of solid versus liquid transport media for high-risk HPV detection and cervical cancer screening on self-collected specimens.

Background: The solid transport media is a small size card that allows fast, easy DNA extraction from a variety of biological samples. In 2016 we developed a solid media transport card; for that pilot study to control the self-collection we used a pseudo-self-collection technique. The current study expands this prior work using true self-collections and only the POI card, and aims to evaluate the solid media transport card to detect HR-HPV in self-samples compared to liquid transport media.

Thermocoagulation versus cryotherapy for the treatment of cervical precancers.

Aim: To compare thermocoagulation and cryotherapy for treatment of high-grade cervical intraepithelial neoplasia (CIN).

Methods: From May 2017 to May 2018, women with CIN2/3 were randomized to thermocoagulation or cryotherapy at Peking University Shenzhen Hospital. Follow-up at 4 and 8 months included cytology and human papillomavirus (HPV) testing.

Evaluating the Performance of p16 Immunocytochemistry in Cervical Cancer Screening.

Purpose: When used for cervical cancer primary screening, liquid-based cytology (LBC) has a high specificity but a low sensitivity. For histological diagnosis of high-grade lesions, p16 immunostaining has proven to be useful. Therefore, our objective was to evaluate the use of p16 immuno-cytology as a primary screen and a secondary screen after primary high-risk human papillomavirus (hrHPV) screening or LBC screening.

The effectiveness of human papillomavirus load, reflected by cycle threshold values, for the triage of HPV-positive self-samples in cervical cancer screening.

Objective: The performance of Cobas4800 cycle threshold value (Ct-value, reflecting viral load) combined with human papillomavirus (HPV) 16/18 genotyping was explored as a method of risk stratification to triage patients after primary HPV screening of self-collected samples.

Methods: The Chinese Multi-site Screening Trial database was reviewed, with focus on self-collected samples, using the results of Cobas4800 HPV assay. Quartiles of Ct-values of each genotype were used for grouping and developing screening algorithms.

The effectiveness of HPV viral load, reflected by Cobas 4800 HPV-Ct values for the triage of HPV-positive women in primary cervical cancer screening: Direct endocervical samples.

Objective: To explore the relationship between the viral load reflected by the Ct value of Cobas 4800 HPV test and cervical lesions, and the effectiveness of the viral load for secondary triage of HPV-positive women.

Methods: The Chinese Multi-Center Screening Trial (CHIMUST) evaluated both self-collected samples and physician-collected samples from women, aged 30 to 59, who were screened for cervical cancer in 6 regions across China. Using physician collected samples, the relationship between the HPV-Ct values of different subtypes and the cervical lesions was analyzed.

Key Determinants of the Value of Random Cervical Biopsy at Colposcopy.

Objective: The aim of the study was to assess whether lower proportions of cervical intraepithelial neoplasia 2+ diagnosed by random biopsy are from lower cut points defining an abnormal colposcopic impression or obtaining only one random biopsy when colposcopic impression is normal.

Methods: We compared colposcopy experiences within Shanxi Province Cervical Cancer Screening Study (SPOCCS) (n = 1,383) and Shenzhen Cervical Cancer Screening Trial (SHENCCAST) (n = 631), which had instructive differences in the cut point defining an abnormal colposcopic impression.

Results: The proportion of CIN 2+ diagnosed by random biopsy in SPOCCS (35.

Evaluation of alternately combining HPV viral load and 16/18 genotyping in secondary screening algorithms.

Background: Correlation with HPV viral load and worsening cervical lesions had been reported, but its potential for triage after primary HPV screening has not been adequately explored, especially when combined with HPV-16/18 genotyping.

Objective: To evaluate combinations of human papillomavirus (HPV) viral load and genotyping for HPV-16/18 as secondary screening strategies.

Methods: The Shenzhen Cervical Cancer Screening Trial Ⅱ (SHENCCAST Ⅱ) database was re-analyzed to explore new screening algorithms using the results of Hybrid Capture 2 (HC2), Mass Array Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass spectrometry System (MALDI-TOF-MS) and the ThinPrep cytologic test (TCT) obtained by endocervical sampling.

Pregnancy in a woman with untreated bladder exstrophy: a case report.

Objective: To report the management of urinary tract obstruction and infection in a pregnant woman with unrepaired bladder exstrophy.

Case Report: A 27-year-old pregnant woman with unrepaired bladder exstrophy was referred to our hospital with a complaint of bilateral flank pain in the second trimester. After two-dimensional abdominal ultrasound, magnetic resonance imaging and a urine analysis, she was diagnosed with an upper urinary tract infection due to ureteral obstruction secondary to unrepaired congenital bladder exstrophy and an intrauterine pregnancy.

HPV L1 and P16 Expression in CIN1 to Predict Future CIN2.

The goal of this study was to use the biomarkers human papillomavirus (HPV) L1 and p16 to develop an algorithm that could triage the individual patient with CIN1 at risk for progression. A total of 82 patients initially diagnosed with CIN1 at Peking University Shenzhen Hospital in China had their initial and follow-up paraffin-embedded tissue blocks immune-stained for HPV L1 capsid protein and p16. For CIN1, any staining of abnormal epithelium was considered positive.

Evaluation of Viral Load as a Triage Strategy With Primary High-Risk Human Papillomavirus Cervical Cancer Screening.

Objective: The aim of the study was to evaluate the human papillomavirus (HPV) viral load combined with cytology as a secondary screening strategy after primary HPV screening.

Materials And Methods: The data referring to direct Hybrid Capture 2 (HC2), cytology, and histology from Shenzhen Cervical Cancer Screening Trial II were re-analyzed to determine the correlation between viral load and cervical lesions. In addition, algorithms using different viral loads as cut points for immediate colposcopy plus cytology triage were compared with several recommended or controversial primary screening methods.
