Beijing, Beijing MunicipalityAges 18 years+ - NCT05786742Recruiting
Radiation plan test for early prostate cancer with a boost
This trial tests a more concentrated radiation schedule for early-stage prostate cancer, using an extra high-dose “boost” delivered from inside the body. It may help by treating the prostate more precisely while aiming to keep side effects manageable.
QuébecAges 18–95 - NCT06051240RecruitingPhase 2
Lithium to prevent thinking problems after brain radiation
This study tests if the drug lithium can help prevent memory and thinking problems that sometimes happen after brain radiation for a brain tumor. You may qualify if you are under 18 when treated and had radiation within the last 7 years.
Solna, Stockholm CountyAges 5 years+ - NCT06306170Recruiting
Advanced radiation for gynecologic cancer
This trial is for people with gynecologic cancer who will receive modern, targeted radiation therapy. It aims to see how well these advanced treatments work and how patients feel during and after therapy.
Milan, MIAges 18–90 - NCT06311955RecruitingPhase 2
Carbon ion radiation for residual thymus tumor after surgery
This trial tests a type of radiation called carbon ion therapy for people with thymus cancer that was not completely removed during surgery. The goal is to see if this treatment can target the remaining tumor cells safely and effectively.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06311981RecruitingPhase 2
Carbon ion radiation for elderly lung cancer patients
This trial tests carbon ion radiotherapy for adults 75 and older with locally advanced non-small cell lung cancer who cannot have surgery. The goal is to see if this precise type of radiation can treat the cancer effectively with fewer side effects.
Shanghai, Shanghai MunicipalityAges 75 years+ - NCT06321653Recruiting
Lymphedema after radiation for early breast cancer with 1-2 positive nodes
This trial aims to see if a shorter course of radiation after breast-conserving surgery affects arm swelling (lymphedema) in people with early breast cancer that has spread to 1 or 2 nearby lymph nodes. The goal is to learn if this approach is safe and effective.
MilanAges 18 years+ - NCT06525181Recruiting
AI Symptom Tracking for Pelvic Radiation Therapy
This trial uses an AI tool to help track your weekly symptoms during pelvic radiation therapy. It aims to make it easier for you and your care team to monitor and manage side effects.
Rio de JaneiroAges 18 years+ - NCT06719440Recruiting
Better outcome by shrinking radiation target for glioblastoma
This trial tests a smaller radiation target for newly diagnosed glioblastoma to reduce side effects while keeping treatment effective. It may help patients who are healthy enough for standard chemoradiotherapy.
AalstAges 18 years+ - NCT06752239RecruitingPhase 3
Optimizing radiation to protect thyroid in nasopharyngeal cancer
This trial tests a way to adjust radiation therapy to better protect the thyroid gland during treatment for nasopharyngeal carcinoma. It aims to reduce thyroid damage while still effectively treating the cancer.
