Most oesophageal carcinomas (>70%) are squamous cell carcinomas (SCC) arising from the surface epithelial lining. In the gastro-oesophageal junction (GEJ) adenocarcinomas occur in the setting of Barrett oesophagus (BE). These carcinomas typically present with surface ulceration. The authors report a rare case of a SCC of the GEJ with completely intramural growth underneath intact non-dysplastic oesophageal squamous epithelium and BE without dysplasia. The sharply demarcated tumour was located in the muscularis propia with infiltration of perioesophageal tissue nearly reaching the diaphragm. Intramural squamous carcinomas are very rare with only three reported cases. In this study, the authors discuss this finding and review the relevant literature. Intramural carcinomas are a diagnostic challenge for clinicians and pathologist, since preoperative biopsies mostly fail to establish the diagnosis and surgical explorations must be considered.

Sensitivity to Environmental Stress and Adversity and Lung Cancer.
JAMA Netw Open
January 2025
Division of Cancer Epidemiology and Genetics, National Cancer Institute, National Institutes of Health, Rockville, Maryland.
Importance: Sensitivity to environmental stress and adversity may influence lung cancer risk, highlighting a critical link between psychosocial factors and cancer etiology.
Objective: To evaluate whether genetically estimated sensitivity to environmental stress and adversity is associated with lung cancer risk.
Design, Setting, And Participants: Data were obtained from a genome-wide association study identifying 37 independent genetic variants strongly associated with sensitivity to environmental stress and adversity and a cross-ancestry genome-wide meta-analysis from the International Lung Cancer Consortium.
Imiquimod Cream Preceded by Superficial Curettage vs Surgical Excision for Nodular Basal Cell Carcinoma: A Secondary Analysis of a Randomized Clinical Trial.
JAMA Dermatol
January 2025
Department of Dermatology, Maastricht University Medical Centre, Maastricht, the Netherlands.
Background: Interest in noninvasive treatment of basal cell carcinoma (BCC) has been increasing. For superficial BCC, it has been demonstrated that imiquimod cream, 5%, has high long-term efficacy, but for nodular BCC (nBCC), long-term evidence is sparse.
Objectives: To evaluate whether superficial curettage (SC) followed by imiquimod cream, 5%, is noninferior to surgical excision (SE) in nBCC after 5 years of treatment.
CD155 promotes the advancement of hepatocellular carcinoma by suppressing the p53-mediated ferroptosis via interacting with CD96.

Hospital Sensory Department, Shenzhen Qianhai Shekou Free Trade Zone Hospital, 36 Gongye Qi Road, Nanshan District, Shenzhen, 518067, China.
This work researched the influence and mechanism of CD155 on hepatocellular carcinoma advancement. CD155 expression and its effect on survival of hepatocellular carcinoma patients were analyzed based on the GEPIA2 database. String software predicted the interacting between CD155 and CD96, which was further verified by co-immunoprecipitation experiment.

Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of the p16-pRb pathway by constitutive expression of mutant cyclin-dependent kinase 4 (R24C) (CDK4) and cyclin D1, and ii) acquisition of telomerase reverse transcriptase (TERT) activity, we established a human ovarian endometrioid carcinoma cell line from a 46-year-old Japanese woman. That line, designated JFE-21, has proliferated continuously for over 6 months with a doubling time of ~ 55 h.

J Epidemiol Glob Health

Center of Clinical Laboratory, Zhongshan Hospital of Xiamen University, School of Medicine, Xiamen University, No.201-209 Hubinnan Road, Xiamen, 361004, China.
Background: During the COVID-19 outbreak in December 2022 in China, some laboratory workers in SARS-CoV-2 nucleic acid testing (NAT) laboratories remained uninfected.
Objectives: To evaluate if the incidence of SARS-CoV-2 infection was reduced in laboratory workers who performed SARS-CoV-2 NAT, and whether this reduction resulted from the healthy worker effect.
Methods: This retrospective cohort study included 423 laboratory workers from 14 SARS-CoV-2 NAT laboratories in Xiamen, China.
