MunichAges 18 years+ - NCT06734598RecruitingPhase 4
Botox for Jaw Tightness After Head and Neck Radiation
This study tests whether Botox injections into the jaw muscles can help head and neck cancer survivors who have trouble opening their mouths (trismus) after radiation therapy. If you have tight or painful jaw muscles and limited mouth opening, this treatment may offer relief.
TaipeiAges 18 years+ - NCT06739655Recruiting
Radiation before surgery with breast reconstruction
This trial tests whether giving radiation therapy before surgery (instead of after) is safe and effective for women with breast cancer who also want immediate breast reconstruction. It could help avoid the need for a second surgery and improve recovery.
Edegem, AntwerpenAges 18 years+ - NCT06743789Recruiting
Radiation therapy for ventricular tachycardia: one or three sessions
This trial tests whether a single session of targeted radiation (radioablation) is as effective as three sessions for treating a dangerous heart rhythm called ventricular tachycardia in people with heart muscle disease. It's for those who continue to have episodes despite medication and catheter ablation.
New York, New YorkAges 18–90 - NCT06758830RecruitingPhase 2/Phase 3
Total neoadjuvant therapy vs surgery for rectal cancer
This trial tests whether a full course of chemotherapy and radiation before any surgery (called total neoadjuvant therapy) can help you avoid surgery and preserve your rectum. It is for people with a specific early stage of rectal cancer that has not spread.
VilniusAges 18 years+ - NCT06766643RecruitingPhase 2
Stereotactic radiosurgery vs. radiofrequency ablation for liver cancer
This study compares two nonsurgical procedures for liver cancer: stereotactic radiosurgery (focused radiation) and radiofrequency ablation (heat therapy). It is for people whose tumor is in a tricky spot near major blood vessels or other structures, making surgery difficult, and who have not received prior treatment.
TianjinAges 18–75 - NCT06769126RecruitingPhase 2
Personalized treatment study for extensive stage small cell lung cancer
This study uses biomarker tests on your tumor to find a personalized treatment after initial chemotherapy. You will be assigned to one of four treatment groups based on your biomarker results.
