Study on the metastatic mechanism of LINC00115 in adenocarcinoma of the Esophagogastric junction.

Adenocarcinoma of the esophagogastric junction (AEG) is a common and deadly cancer, and an in-depth investigation of its molecular mechanisms of metastasis is crucial for discovering new therapeutic targets. This study explores the role of the long non-coding RNA (lncRNA) LINC00115 in AEG metastasis and its underlying mechanisms. Through the analysis of 108 pairs of AEG cancer tissues and matched adjacent tissues, we found a significant upregulation of LINC00115 in AEG tissues, closely associated with TNM staging and lymph node metastasis.

A 78-year-old male patient came to our hospital with a chief complaint of fever. Computed tomography revealed an indistinct tumor in the pancreatic head, along with dilatation of the bile duct and main pancreatic duct. An endoscopic transpapillary biopsy demonstrated adenocarcinoma in the glandular epithelium and a dense formation of quasi-round cells.

Concurrent malignant biliary and gastric outlet obstruction requires urgent palliative intervention to improve patient quality of life and permit systemic therapy. Traditional management has been surgical gastrojejunostomy and hepaticojejunostomy, two morbid procedures. Comparatively, endoscopic stenting can relieve both sites of obstruction with less complications and quicker recovery.

Department of Pathology, Kansai Medical University, 2-5-1 Shin-machi, Hirakata, Osaka 573-1010, Japan. Electronic address:
Context: Hepatocyte nuclear factor (HNF)-4α is a marker of gastrointestinal tumor differentiation; however, its expression in endocervical tumors remains unclear.
Objective: We aimed to assess the utility of HNF4α expression as a marker for endocervical adenocarcinomas (ECAs) and adenocarcinoma in situs (AISs), and to establish a minimal panel for distinguishing them from nonneoplastic endocervical glandular lesions and metastases.
Design: HNF4α expression was analyzed immunohistochemically (positive, H-score ≥ 10) in 323 tissue samples: 57 endocervical neoplasms including 35 glandular neoplasms and 22 squamous neoplasms, 144 nonneoplastic endocervical lesions, and 122 tumors from other organs.
Applying Results of Extended Genotyping to Management of Positive Cervicovaginal Human Papillomavirus Test Results: Enduring Guidelines.
J Low Genit Tract Dis

Division of Cancer Epidemiology & Genetics, National Cancer Institute, Rockville, MD.
Objective: The Enduring Consensus Cervical Cancer Screening and Management Guidelines Committee developed recommendations for the use of extended genotyping results in cervical cancer prevention programs.
Methods: Risks of cervical intraepithelial neoplasia grade 3 or worse were calculated using data obtained with the Onclarity HPV Assay from large cohorts. Management recommendations were based on clinical action thresholds developed for the 2019 American Society for Colposcopy and Cervical Pathology Risk-Based Management Consensus Guidelines.
