Clear cell sarcoma (CCS) of the parotid gland is a rare and aggressive cancer, predominantly affecting the deep soft tissues of the lower extremities, and is more frequently observed in the elderly. Its occurrence in the head and neck area, particularly in the parotid gland, is exceedingly rare. This study presents a 75-year-old male who exhibited a substantial, swiftly-enlarging mass on the left side of the mandible, which was diagnosed as CCS of the parotid gland.

- This study assesses a biodegradable balloon rectal spacer for two prostate cancer patients receiving low dose (LDR) and salvage high dose (HDR) radiation therapy to protect the rectum from radiation exposure.
- The spacer was successfully implanted using ultrasound guidance, creating a 14-15mm gap between the prostate and rectum, with dosimetry metrics indicating effective radiation delivery to the prostate while minimizing rectal dose.
- Both patients tolerated the procedure well, experiencing no complications during a 6-month follow-up, suggesting the spacer is a safe and effective tool in radiation therapy for prostate cancer.
Background: Ventricular tachycardia (VT) is a life-threatening arrhythmia originating from the heart's ventricles. Traditional treatments include antiarrhythmic medications, implantable cardioverter-defibrillators (ICDs), and catheter ablation. Stereotactic body radiation therapy (SBRT) targeting the arrhythmogenic focus in the left ventricle-stereotactic arrhythmia radioablation (STAR)-is an emerging treatment and may offer a potential solution for patients with refractory VT.

Currently, the prevention of these three cancers faces various obstacles, such as a lack of specialized screening programs, well-defined management guidelines, and widespread public awareness. Without any interventions, the incidence of these three cancers will likely rise in the upcoming years, increasingly affecting younger individuals.

However, predicting the response to anti-PD-1 therapy remains a clinical challenge. This study evaluated the functional binding of PD-1 ligands in 29 HNSCC patients and compared it to the standard PD-L1 Combined Positive Score (CPS).
