Flexible Cervical Photodynamic Therapy Device

Translational Biophotonics, EarlyView.
This paper aims to design a flexible photodynamic therapy device for the cervix and cervical vault, using an LED array, light guide, and flexible trumpet‐shaped homogenizer. Simulations and tests show output irradiance up to 98 mW/cm2 with < 14.2% variation, offering a low‐cost solution for cervical cancer and precancerous lesions.

CEA Levels in Gastric Juice in Precancerous Conditions and Cancer

The International Journal of Biological Markers, 1987
First described in 1965 as a specific antigen for cancer of the colon, CEA is now considered to be an antigen associated with many types of malignant neoplasia, although the CEA-Test's role in clinical routine has yet to be clearly defined. In the present study CEA levels in gastric juice were measured in subjects with gastric carcinoma (n = 25) and ...

Effectiveness of Gastric Cancer Endoscopic Screening in Intermediate‐Risk Countries—A Systematic Review and Meta‐Analysis

United European Gastroenterology Journal, EarlyView.
ABSTRACT Background Gastric cancer remains a major cause of cancer‐related mortality in intermediate‐risk countries. Although endoscopic screening is widely implemented in high‐risk regions, its effectiveness and economic viability in intermediate‐risk settings remain uncertain.

Combined Transcriptomic and Proteomic Forecast Analyses for Potential Biomarkers of Smoking‐Induced Benign and Malignant Transformation of Vocal Fold Lesions

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Laryngeal dysplasia and Reinke's edema (RE) are common vocal fold lesions associated with smoking. While the former is cancer prone, most cases of the latter do not undergo malignant transformation. Therefore, we proposed identifying biomarkers of smoking‐induced benign‐malignant transformation of vocal fold lesions.

"Catch them before it becomes too late"-oral cancer detection. Report of two cases and review of diagnostic AIDS in cancer detection

International Journal of Preventive Medicine, 2012
Most oral and oropharyngeal squamous cell carcinomas (OOSCCs) are in advanced stages at diagnosis, and treatment does not improve survival rates. Early recognition and diagnosis of OOSCCs might improve patient survival and reduce treatment-related ...

hTERT Increases TRF2 to Induce Telomere Compaction and Extend Cell Replicative Lifespan

Aging Cell, EarlyView.
In contrast to the dogma that a subset of short telomeres initiates senescence, hTERT variants unable to maintain telomere length block senescence by stabilizing TRF2 via inhibiting upstream E3 ubiquitin ligases. This noncanonical hTERT function also compacts telomeres and blocks senescence‐associated DNA damage signaling. Cancer cells expressing hTERT

Epigenetically‐Upregulated CD98 Shed Light on the Precancerous Diagnosis and Prognosis Prediction of Esophageal Cancer

Cancer Science, EarlyView.
This study confirmed that hypomethylation‐induced upregulation of CD98 promoted ESCC cell proliferation by regulating the cell cycle and was correlated with poorer overall survival of ESCC patients. Combined panels of immunohistochemistry (CD98 and P53) are recommended for accurate diagnosis of esophageal precancerous lesions.
