The role of human papillomavirus (HPV) in esophageal cancers was evaluated in patients seen at Johns Hopkins University Hospital. Frozen esophageal tumor tissues from 22 cases with squamous cell carcinoma (SCC) and 24 cases with adenocarcinoma (AC), diagnosed between 1988 and 1998, were assayed for HPV sequences by reverse line blot polymerase chain reaction. HPV sequences (HPV-54) were detected in a single specimen; the other 45 specimens were negative. The HPV sequences in the positive specimen may represent infection of the epithelium. Our results suggest that genital HPVs may sometimes infect the esophagus, but there is no evidence to indicate that these infections contribute substantially to the development of esophageal cancer in North America.

Background: It is crucial to identify post-operative patients with HPV infection who are at high risk for residual/recurrent disease. This study aimed to evaluate the association between HPV integration and clinical outcomes in HPV-positive women after cervical conization, as well as to identify HPV integration breakpoints.
Methods: This retrospective study analyzed data of 791 women who underwent cervical conization for cervical intraepithelial neoplasia grades 2-3 (CIN2-3) between September 2019 and September 2023, sourced from the Fujian and Hubei cervical lesion screening cohorts.

Background: Cervical cancer is the fourth most common cancer worldwide in females. This occurs primarily due to the infection of high-risk Human Papilloma Virus (HPV), although in advanced stages it requires support from host cellular factors. BRN3A is one such host cellular factors, whose expression remains high in cervical cancers and upregulates tumorigenic HPV gene expression.

Upon infection, human papillomavirus (HPV) manipulates host cell gene expression to create an environment that is supportive of a productive and persistent infection. The virus-induced changes to the host cell's transcriptome are thought to contribute to carcinogenesis. Here, we show by RNA-sequencing that oncogenic HPV18 episome replication in primary human foreskin keratinocytes (HFKs) drives host transcriptional changes that are consistent between multiple HFK donors.

Vulvar adenocarcinoma of the intestinal type (VAIt) is a rare subtype of primary vulvar carcinoma, with ∼30 cases documented in the English literature. This study presents 2 new cases of HPV-independent VAIt with lymph node metastasis and discusses their clinical presentation, histopathologic features, and whole exome sequencing (WES) analysis. Both cases exhibited histologic features consistent with VAIt, including tubular, papillary, and mucinous carcinoma components.

The term verruciform acanthotic vulvar intraepithelial neoplasia (vaVIN) was coined to describe HPV-independent p53-wildtype lesions with characteristic clinicopathologic characteristics and association with vulvar squamous cell carcinoma (vSCC). We aimed to expand on the molecular landscape of vaVIN using comprehensive sequencing and copy number variation profiling. vaVIN diagnosis in institutional cases was confirmed by a second review, plus negative p16 and wildtype p53 by immunohistochemistry.
