RomeAges 18–75 - NCT05903430Recruiting
MRI-guided focused radiation for limited spread cancer
This feasibility study tests whether MRI-guided, highly focused radiation can be safely delivered to tumors in the abdomen or central lung. It may help patients with a small number of metastases by aiming treatment more precisely and gathering detailed outcomes for future care.
Manchester, United KingdomAges 18 years+ - NCT06508567Recruiting
MRI-Guided Internal Radiation for Returning Prostate Cancer
This trial tests a new way to use a type of internal radiation (high-dose-rate brachytherapy) guided by MRI to treat prostate cancer that has come back in the same area after previous radiation therapy. It is designed to be more precise and hopefully safer while using the latest PSMA PET scans to make sure the cancer hasn't spread.
Toronto, OntarioAges 18 years+ - NCT06506435Recruiting
Radiation therapy education using virtual reality
This study tests whether watching a virtual reality video before radiation therapy helps you understand the treatment better. It is for people with cancer who are starting radiation therapy at the University of Miami.
Miami, FloridaAges 18 years+ - NCT06498154RecruitingPhase 2
Skipping breast surgery for some patients after chemo
This trial tests whether women with certain aggressive breast cancers (HER2-positive without hormone receptors, or triple-negative) can safely skip breast surgery if chemotherapy makes their tumor completely disappear. The goal is to avoid surgery and its side effects when it may no longer be needed.
TianjinAges 18–70 - NCT06477692RecruitingPhase 2
Comparing Neck Radiation Options for Head and Neck Cancer
This trial is testing whether radiation to just the lymph nodes near the tumor is as effective as treating a larger area of the neck. It is for people with certain head and neck cancers (not unknown primary or glottic) and aims to lower side effects.
Dallas, TexasAges 18–99 - NCT06479070Recruiting
Using ctDNA to guide radiotherapy for head and neck cancer
This study looks at whether measuring a DNA fragment in the blood (called ctDNA) can help predict how well radiotherapy works for head and neck cancer. It may help doctors better tailor treatment for patients with stage III or IV disease.
Caen, CaenAges 18 years+ - NCT05236946RecruitingPhase 3
Brain radiation timing study for gene-mutated lung cancer
This study compares giving brain radiation right away versus waiting, in people with lung cancer that has an EGFR or ALK gene change and has spread to the brain but causes no symptoms. It aims to see which approach helps control the brain cancer better and keeps quality of life stable.
Mumbai, MaharashtraAges 18–99 - NCT05387603RecruitingPhase 3
Targeted radiation for certain advanced neuroendocrine tumors
This Phase 3 study tests whether a targeted radiation treatment approach (using a special “PRRT” scan-guided method) works better to control advanced neuroendocrine tumors. It’s designed for tumors that show strong targeting on a specific PET scan and that are growing despite prior treatment (with some limits).
GothenburgAges 18 years+ - NCT06470282RecruitingPhase 1/Phase 2
Drug combo plus radiation for muscle-invasive bladder cancer
This trial tests a combination of two drugs (enfortumab vedotin and pembrolizumab) plus radiation therapy for people with bladder cancer that has grown into the muscle layer. The goal is to see if this treatment can kill the cancer while avoiding the need for bladder removal surgery.
San Francisco, CaliforniaAges 18 years+ - NCT06470503Enrolling by invitation
Exercise after radiation for bone metastases
This study tests whether a supervised exercise program helps people with cancer that spread to their bones feel stronger and move better after radiation treatment. It is designed for people who can walk independently and have stable bones.
Toronto, OntarioAges 18 years+ - NCT06457906RecruitingPhase 3
Focused radiation vs whole brain radiation for up to 10 lung cancer brain spots
This trial compares two types of radiation for people with small cell lung cancer that has spread to the brain (10 or fewer spots). One approach uses focused radiation only on the tumors, the other treats the whole brain while trying to protect memory. The goal is to see which works better with fewer side effects.
Beijing, Beijing MunicipalityAges 18–80 - NCT06428045RecruitingPhase 1
STARLITE for hard-to-surgery high-grade brain tumors
This trial tests a new treatment called STARLITE for people with fast-growing brain tumors (high-grade gliomas) that cannot be safely removed with surgery. The treatment uses a laser to destroy the tumor from the inside. It may be a good option if you haven't had any prior treatment for this tumor.
Miami, FloridaAges 18 years+ - NCT06429995Enrolling by invitation
Standard follow-up program for breast cancer patients
