Exacerbation of previously undetected ulcerative colitis in a patient undergoing nivolumab for metastatic melanoma: A case report Open
Rationale: In patients receiving immune checkpoint inhibitors, subclinical inflammatory bowel disease can be unmasked, leading to severe colitis. Ulcerative colitis, in particular, may remain undetected when initial symptoms are mild. This…

Expression of Keratin-1 Predicts Recurrence and Treatment Response in Advanced Laryngeal Cancer: A Potential Therapeutic Target Open
The survival rate of patients with advanced laryngeal cancer has not substantially improved over time. RNA sequencing analysis identified Keratin-1 (KRT1) as a gene potentially associated with cancer recurrence. This study investigated the…

Usefulness of the human papillomavirus DNA chip test as a complementary method for cervical cytology Open
Objectives: As a convenient and economical method of screening cervical cancer and precancerous pathologies, the Papanicolaou smear (Pap smear) has been most widely used. Nevertheless, it requires cytological changes for making diagnoses a…

Neurenteric cyst of the craniovertebral junction treated to reduce recurrence using different strategies: Two case reports and a literature review Open
Rationale: Neurenteric cysts are rare benign lesions that are usually located in the lower cervical and upper thoracic spine and extremely rare in the craniovertebral junction. It is generally challenging to completely remove the neurenter…

Bronchial brushing cytology is comparable to bronchial biopsy for epidermal growth factor receptor mutation test in non-small cell lung cancer Open
Objectives: Bronchial brushing (BB) is often used to obtain supplementary samples for diagnosing lung cancer. We examined the possibility of epidermal growth factor receptor (EGFR) testing on BB samples and compared them with bronchial bio…

APE1 Promotes Pancreatic Cancer Proliferation through GFRα1/Src/ERK Axis-Cascade Signaling in Response to GDNF Open
Pancreatic cancer is the worst exocrine gastrointestinal cancer leading to the highest mortality. Recent studies reported that aberrant expression of apurinic/apyrimidinic endodeoxyribonuclease 1 (APE1) is involved in uncontrolled cell gro…
