BACKGROUND: Development demand of precise medicine in resectable esophageal squamous cell carcinoma (ESCC) require to recognize patients at high risk treated by surgery alone. Thus, our aim was to construct a clinical nomogram and recursive partitioning analysis (RPA) to predict long-term survival in ESCC treated by surgery alone. METHODS: Based on the patients with ESCC who treated by three-incisional esophagectomy and two-field lymphadenectomy alone, we identified and integrated significant prognostic factors for survival to build a nomogram...

Health systems are stewards of patient electronic health record (EHR) data with extraordinarily rich depth and breadth, reflecting thousands of diagnoses and exposures. Measures of genomic variation integrated with EHRs offer a potential strategy to accurately stratify patients for risk profiling and discover new relationships between diagnoses and genomes. The objective of this study was to evaluate whether polygenic risk scores (PRS) for common cancers are associated with multiple phenotypes in a phenome-wide association study (PheWAS) conducted in 28,260 unrelated, genotyped patients of recent European ancestry who consented to participate in the Michigan Genomics Initiative, a longitudinal biorepository effort within Michigan Medicine...

Long non-coding RNAs (lncRNA) were discovered in tumors. The regulation of lncRNA in human laryngeal squamous cell carcinoma (LSCC) remains incomplete. Uncovering the potential of lncRNA to stratify the prognosis of LSCC and streamline the vast amount of clinical information will affect medical interventions. The surgical resected LSCC tissues, adjacent non-cancerous tissues (ANCT) and lymph node metastatic tissue (LNM) were collected from 76 patients for lncRNA AC008440.10 expression assay. The stages of LSCC and LNM were classified accordingly...

The mouse vagina consists of stratified squamous epithelium and stroma and is regulated by ovarian hormones. Vaginal epithelial cells do not stratify, but rather form a monolayer and show an inconsistent responsiveness to ovarian hormones when cultured on plastic dish or matrix. To address the discrepancy between in vivo and in vitro observations, 3 dimensional (3D) co-culture models are developed with clonal vaginal epithelial and stromal cell lines; stromal cells are embedded in collagen gel and epithelial cells are seeded on the gel...

BACKGROUND: Oligometastasis is a good prognostic indicator when compared to widely metastatic disease in malignancies of other organ systems. We hypothesized that oligometastasis in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (SCC) would be associated with better overall survival. METHODS: This is a retrospective review of all HPV-positive oropharyngeal SCC treated at one center with at least 1-year of follow-up. Patients were stratified into 2 cohorts: oligometastasis (1-2 metastases, confined to 1 organ system) or polymetastasis (>2 metastases or multiple organ involvement) with cohorts compared for time to distant metastasis and overall survival after metastasis...

High genome copy number (viral load) of human papillomavirus (HPV) is being discussed as a risk factor for high-grade cervical lesions. However, conflicting data about the integration status or viral load of the virus as risk factors for prevalent high-grade squamous intraepithelial lesions (HSIL) are found in the literature. To investigate whether viral load and/or integration status are indicative for prevalent ASCUS/LSIL or HSIL, we determined the HPV16 viral load and the physical state of the genome in 644 women with single HPV16 infections stratified by their cytology results from a large Danish population-based cohort consisting of 40,399 women...

The stratified squamous epithelium of the esophagus shows a proliferative basal layer of keratinocytes that undergo terminal differentiation in overlying suprabasal layers. Esophageal pathologies, including eosinophilic esophagitis, gastroesophageal reflux disease, Barrett's esophagus, squamous cell carcinoma, and adenocarcinoma, cause perturbations in the esophageal epithelial proliferation-differentiation gradient. Three-dimensional (3D) culture platforms mimicking in vivo esophageal epithelial tissue architecture ex vivo have emerged as powerful experimental tools for the investigation of esophageal biology in the context of homeostasis and pathology...

The diagnosis of squamous intraepithelial lesions in cervical tissue specimens is subject to substantial variability. Adjunctive immunohistochemical (IHC) staining for p16 has been shown to add objective biomarker information to morphologic interpretation of hematoxylin and eosin (H&E)-stained tissues. In the CERvical Tissue AdjunctIve aNalysis (CERTAIN) study, we systematically analyzed the impact of adjunctive p16 IHC on the accuracy (agreement with reference pathology results) of diagnosing cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) in the United States...
