Background: The main goal of cervical screening programs is to detect and treat precancer before cancer develops. Human papillomavirus (HPV) testing is more sensitive than cytology for detecting precancer. However, reports of rare HPV-negative, cytology-positive cancers are motivating continued use of both tests (cotesting) despite increased testing costs. Methods: We quantified the detection of cervical precancer and cancer by cotesting compared with HPV testing alone at Kaiser Permanente Northern California (KPNC), where 1 208 710 women age 30 years and older have undergone triennial cervical cotesting since 2003...

Roche cobas 4800 human papillomavirus (HPV) test is an automated real-time polymerase chain reaction-based system that allows the simultaneous detection of 14 human papillomavirus high-risk (HR-HPV) genotypes. This test is Food and Drug Administration approved since 2011 for HPV determination in liquid-based cytologic samples, but a clinically validated technique for formalin-fixed, paraffin-embedded (FFPE) tissue specimens is presently not commercially available. In our laboratory, we have developed an HPV detection procedure in FFPE tissue by cobas 4800 HPV test...

Oral premalignant lesions (OPLs) such as leukoplakia, erythroplakia, and oral submucous fibrosis, often precede oral cancer. Screening and management of these premalignant conditions can improve prognosis. Raman spectroscopy has previously demonstrated potential in the diagnosis of oral premalignant conditions (in vivo), detected viral infection, and identified cancer in both oral and cervical exfoliated cells (ex vivo). The potential of Raman exfoliative cytology (REC) in identifying premalignant conditions was investigated...

Most human papillomavirus (HPV) infections are transient and additional triage approaches should be built after HPV-based primary cervical cancer screening. We evaluated the accuracy of p16/Ki-67 and p16/mcm2 dual staining as biomarkers for triaging HPV positive women in China. 4070 participants aged 35 to 64 years attending ongoing cervical cancer screening were enrolled in 2015-2016. Cervical exfoliated cells were collected for HPV DNA analysis and the residual positive specimens were tested for liquid-based cytology and biomarkers...

BACKGROUND AND OBJECTIVES: Trachelectomy, a fertility-sparing surgery for early-stage cervical cancer, can be performed only when there is no extrauterine extension present. Therefore, identifying the sentinel lymph nodes (SLNs) and using them to obtain an intraoperative pathologic diagnosis can provide information on the feasibility and safety of trachelectomy. Our aim was to assess the value of an intraoperative SLN diagnosis. METHODS: We retrospectively analyzed the accuracy of intraoperative imprint cytology and frozen-section examination in 201 patients at our institution in whom trachelectomy was planned...

BACKGROUND: Self-sampling for human papillomavirus (HPV) offered to women who do not participate in cervical cancer screening is an increasingly popular method to increase screening coverage. The rationale behind self-sampling is that unscreened women harbour a high proportion of undetected precancer lesions. Here, we compare the cervical intraepithelial neoplasia grade 2 or worse (⩾CIN2) detection rate between non-attenders who participated in self-sampling and women attending routine screening...

In 1994, a pilot program of cervical cancer screening was introduced in the Alsace region, France. Women aged 25-65 years were proposed to have one Pap smear every 3 years. The objective was to assess cervical morbidity in Alsace before the human papillomavirus vaccinated population reaches the age of screening. Data on cervical lesions and cancers were collected by EVE for the period September 2008 to August 2011 from existing medical services and cytopathology laboratories in Alsace. Cytological and histological data were completed with data from the two cancer registries covering the region (Bas-Rhin and Haut-Rhin)...

OBJECTIVE: To explore the HPVgenotype profile in Norwegian women with ASC-US/LSIL cytology and the subsequent risk of high-grade cervical neoplasia (CIN 3+). METHODS: In this observational study delayed triage of ASC-US/LSIL of 6058 women were included from 2005 to 2010. High-risk HPV detection with Hybrid Capture 2 (HC2) was used and the HC2+ cases were genotyped with in-house nmPCR. Women were followed-up for histologically confirmed CIN3+ within three years of index HPV test by linkage to the screening databases at the Cancer Registry of Norway...

BACKGROUND: Incomplete excision of cervical precancer is associated with therapeutic failure and is therefore considered as a quality indicator of clinical practice. Conversely, the risk of preterm birth is reported to correlate with size of cervical excision and therefore balancing the risk of adequate treatment with iatrogenic harm is challenging. We reviewed the literature with an aim to reveal whether incomplete excision, reflected by presence of precancerous tissue at the section margins, or post-treatment HPV testing are accurate predictors of treatment failure...

Non-invasive, self-collected sampling methods for HPV DNA detection in women, which are reliable, efficient, and acceptable have the potential to address barriers to cervical cancer screening in underserved communities, including low-middle income countries (LMIC) such as the island nation of the Federated States of Micronesia (FSM). Urine-based HPV testing has not been rigorously evaluated in clinical trials. A pilot community-based participatory randomized control research project evaluated use of urine HPV testing as a more culturally- and human resource appropriate method of cervical cancer screening in Yap State, FSM...

BACKGROUND: Lobectomy may be sufficient for patients with intrathyroidal papillary thyroid carcinomas (PTC) < 4 cm without nodal metastasis. Based on the 2015 American Thyroid Association guidelines, a strategy using ultrasound to identify appropriate candidates for lobectomy was implemented. METHODS: We retrospectively reviewed patients with Bethesda V or VI cytology who underwent surgery for PTC (January 2016 to May 2017). Eligibility for lobectomy was based both tumor (unilateral, intrathyroidal tumors ≤ 3 cm in size) and non-tumor (history of hypothyroidism, radiation exposure, etc...

Persistence of high-risk human papillomavirus (HPV) represents the necessary cause of cervical cancer. Researching natural history of HPV infection is important to identify high-risk population of cervical cancer. Since HPV infection is population-specific, the findings in western populations could not be simply extended to Chinese and Asian females. This study investigated the type-specific persistence of HPV and related factors among Daqing City women in China. A total of 1759 women aged 18-80 years were enrolled at baseline...
