Wei Zhang, David H Wang
The incidence of esophageal adenocarcinoma has been increasing in Western countries over the past several decades. Though Barrett's esophagus, in which the normal esophageal squamous epithelium is replaced with metaplastic intestinalized columnar cells due to chronic damage from gastroesophageal reflux, is accepted as the requisite precursor lesion for esophageal adenocarcinoma, the Barrett's esophagus cell of origin and the molecular mechanism underlying esophageal epithelial metaplasia remain controversial...

A refinement of quality indicators (QIs) is described whereby the quality of care can be measured across colposcopy services in different countries and healthcare settings. A five-round Delphi process was conducted at successive satellite meetings from 2011 to 2015 of leading European colposcopists to refine the most high-scoring QIs relevant to colposcopic practice. A review and refinement of the wording of the standards and their criteria was undertaken by national society representatives. Six quality indicators were identified and refined...

Cervical intraepithelial neoplasia (CIN) 2 is an equivocal diagnosis, with p16 immunohistochemical positivity currently recommended for diagnostic confirmation. Biomarkers characteristic of squamocolumnar junction cells were recently found to be positive in almost all CIN 2 and CIN 3. CIN 1 lesions which express squamocolumnar junction markers (in particular cytokeratin 7 [CK7]) are associated with a higher rate of subsequent high-grade squamous intraepithelial lesion, suggesting that CK7 may be a useful prognostic biomarker for CIN 1...

OBJECTIVE: To assess the risk of developing high-grade cervical dysplasia among women with low-grade cervical cytology and nonvisible squamocolumnar junction (SCJ) at colposcopic examination. METHODS: Data of consecutive women with low-grade intraepithelial lesion(≤LSIL) undergoing colposcopic examination, which was unsatisfactory (due to the lack of the visualization of the entire SCJ), were retrospectively reviewed. The risk of developing high-grade cervical intraepithelial neoplasia (CIN2+) was assessed using Kaplan-Meier and Cox models...

BACKGROUND: Adenocarcinoma of the esophagogastric junction (EGJ) is uncommon in Eastern countries, including Japan, but it is believed that the incidence of EGJ adenocarcinoma will increase in Asia in the future due to the decreasing incidence of Helicobacter pylori infection. Endoscopic submucosal dissection (ESD) is a minimally invasive and curative treatment that allows precise pathological assessment. SUMMARY: Magnifying endoscopy with narrow-band imaging may be useful for differential diagnoses and for delineating the cancer margin of EGJ adenocarcinoma, but subsquamous carcinoma extension, which is the invasion of EGJ adenocarcinoma beneath the normal esophageal squamous epithelium, makes it difficult to detect cancer margins of the oral side in ESD for EGJ adenocarcinoma...

The aim of this study was to investigate the practical utility of endocervicoscopy and targeted biopsy in high-risk human papilloma virus-positive women with abnormal squamous cells on cervical cytology and unsatisfactory colposcopy with nonvisible squamocolumnar junction. Seventy-seven high-risk human papilloma virus-positive patients with abnormal cervical cytology for squamous cells bearing type 3 transformation zone were enrolled. Endoscopic examination of the endocervical epithelium, with office-based continuous-flow hysteroscopy after application of acetic acid 5%, followed by targeted biopsies and consequent large loop excision of the transformation zone was carried out...

OBJECTIVES: We assessed the performance characteristics of image-enhanced endoscopy with i-Scan or narrow band imaging (NBI) in patients with non-erosive gastroesophageal reflux disease (GERD) compared to controls without heartburn. MATERIAL AND METHODS: Image-enhanced endoscopic findings of vascularity at the squamocolumnar junction, distal esophageal micro-erosions, and non-round pit pattern at the squamocolumnar junction were assessed in cases (heartburn not responsive to PPIs, positive results on validated GERD questionnaire, no esophageal erosions, esophageal biopsies with histologic evidence of GERD (basal cell hyperplasia, elongation of papillae and dilation of intercellular spaces all required)) and in controls (no GERD symptoms or esophageal erosions)...

BACKGROUND & AIMS: It is a challenge to make a diagnosis of eosinophilic esophagitis (EoE) because its symptoms and histologic features overlap with those of gastroesophageal reflux disease (GERD). A minimally invasive device was recently developed to detect mucosal impedance (MI) that measures epithelial integrity during upper endoscopy. We aimed to quantify MI along the esophagus and identify patterns that differentiated patients with and without GERD from those with EoE, and determine whether MI values and patterns are sufficient to identify patients with EoE using histologic findings as a reference...

The favorable features of high-risk human papillomavirus (HPV) in the head and neck are limited to those harboring transcriptionally-active HPV, which occur predominantly in the oropharynx (OP). Factors rendering the OP susceptible to HPV oncogenesis are largely unexplored. The role of cytokeratin 7 (CK7) in predisposition to HPV and cancer in the cervix has been evaluated. However, its significance in the H&N is unknown. CK7 immunohistochemistry was performed on a tissue microarray cohort of OP and non-oropharyngeal (NOP) squamous cell carcinomas (SCC) with known clinical follow-up and HPV E6/7 mRNA status...

Wireless pH monitoring of the esophagus has been widely used to detect GERD for more than a decade. It is generally well tolerated and accepted by patients, but it is still unclear whether prolonging a recording beyond the usual 48 hours can improve the test's diagnostic value. The aim of this study is to examine the diagnostic yield of 96-hour pH monitoring vis-à-vis 24- and 48-hour tests, and to ascertain whether any gain in diagnostic terms was of genuine clinical utility. Patients with suspected GERD underwent 4-day PPI-off wireless pH monitoring of the distal esophagus...

BACKGROUND: HIV-positive individuals have high incidence of anal high-grade squamous intraepithelial lesions (HSIL) at the squamocolumnar junction (SCJ), which can progress to cancer. Focal radiofrequency ablation (RFA) treats HSIL, but metachronous recurrence remains high and may be improved with circumferential treatment. SETTING: The study was performed at a single center. METHODS: This was a prospective trial of circumferential anal RFA using Barrx 60 RFA focal catheters in participants with ≥1 anal SCJ HSIL...

BACKGROUND: Human papillomavirus (HPV)-related anal cancer lesions are often found adjacent to the squamocolumnar junction (SCJ). We have assessed the histopathology and associated HPV genotypes in anal SCJ lesions in surgically excised anal warts in HIV-negative and -positive patients. METHODS: Histopathology identified 47 squamous intraepithelial lesions (SILs) adjacent to the SCJ amongst a total of 145 cases of clinically diagnosed anal condylomata. The anal SCJ lesions were further analyzed with p16, CK7 and p63 immunohistochemistry and HPV genotyping...

BACKGROUND AND AIMS: Barrett's intestinal metaplasia may extend beneath normal squamous epithelium at the squamocolumnar junction (SCJ) and therefore escape surveillance biopsy sampling. The prevalence of subsquamous intestinal metaplasia (SSIM) in patients undergoing Barrett's esophagus (BE) surveillance is unknown. Our aim was to examine the prevalence and distribution of SSIM proximal to the SCJ in patients undergoing BE surveillance. METHODS: We enrolled consecutive patients with biopsy specimen-proven BE...

Quality assurance and research in colposcopy and cervical pathology require standardized terminologies and reporting. However, clinical and histologic definitions of the cervical transformation zone (TZ) and squamocolumnar junction (SCJ) vary considerably. We aimed to identify areas of agreement and areas where work is required to standardize the definitions of the TZ and the SCJ. We conducted a survey among the board members of the European Federation of Colposcopy member societies and members of the International Society of Gynecological Pathologists...
