Targeted radiation for prostate cancer that came back
This study tests a focused (“salvage”) brachytherapy—radiation placed directly near the prostate—to treat prostate cancer that has returned after earlier radiation. It may help control the tumor while limiting radiation exposure to surrounding tissues, based on how well people fit the study’s safety and cancer details.
Poznan, Greater Poland VoivodeshipAges 18 years+ - NCT05754580Recruiting
Boost radiation for intermediate or higher-risk prostate cancer
This study tests a stronger, focused radiation plan for intermediate to higher-risk prostate cancer. It combines a high-dose internal radiation “boost” with external radiation to try to improve cancer control while keeping side effects manageable.
Omaha, NebraskaAges 19 years+ - NCT05772923Recruiting
Testing rectal cancer organ-preservation after radiation
This trial compares two ways to preserve the rectum/avoid major surgery after radiation: a focused contact x-ray treatment versus waiting longer and then removing only a small area if needed. It may help some people keep more normal bowel function while still controlling the cancer.
Nijmegen, GelderlandAges 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 - NCT05894018RecruitingPhase 2
Seed radiation plus fluzoparib for advanced soft tissue sarcoma
This trial tests whether combining seed radiation (iodine-125 placed in/near the tumor) with fluzoparib can better control advanced, hard-to-remove soft tissue sarcoma. It may help shrink tumors and slow progression, but you must meet several cancer, health, and safety requirements.
Guangzhou, GuangdongAges 18 years+ - NCT05979610RecruitingPhase 2
Reiki therapy for symptom relief during gynecologic radiation
This trial tests whether adding Reiki therapy (a gentle hands-on relaxation technique) can help reduce side effects like pain and anxiety during brachytherapy (internal radiation) for women with gynecologic cancers. Participants will be randomly assigned to receive Reiki plus usual care or usual care alone.
Salt Lake City, UtahAges 18 years+ - NCT05984511Recruiting
Combined treatment for liver cancer with portal vein tumor thrombus
This trial tests whether adding immunotherapy (atezolizumab/bevacizumab) and a type of internal radiation (I-125 seeds) to standard chemoembolization (TACE) can help people with liver cancer that has spread into the main liver blood vessel (portal vein). It aims to control the tumor and improve outcomes.
Guangzhou, GuangzhouAges 18–75 - NCT06200974Recruiting
Genetic study of HDR brachytherapy for low-risk prostate cancer
This study looks at a type of radiation therapy called HDR brachytherapy for men with low-risk or slightly higher risk prostate cancer. It aims to understand how your genes affect treatment outcomes.
Kelowna, British ColumbiaAges 18 years+ - NCT06284031Recruiting
Cervical cancer brachytherapy with needles in 3 sessions
This trial tests a special type of radiation, called brachytherapy, given in 3 sessions using thin needles. It is for people with cervical cancer that has not spread too far, and who have already had standard radiation treatment.
SingaporeAges 21 years+ - NCT04945642Recruiting
Radiation combination therapy for intermediate to high-risk prostate cancer
This trial studies a combination of two radiation types—high-dose-rate brachytherapy and stereotactic body radiotherapy—to treat certain intermediate- to high-risk prostate cancers. It may help by aiming radiation closely at the prostate while also targeting the cancer from outside the body.
Los Angeles, CaliforniaAges 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+ - NCT06529809RecruitingPhase 1/Phase 2
Accelerated brachytherapy and chemo for advanced cervical cancer
This trial tests a new way of delivering radiation therapy (brachytherapy) combined with chemotherapy for advanced cervical cancer. The goal is to see if a faster, more intense radiation schedule is safe and effective.
St Louis, MissouriAges 18 years+ - NCT06560697Recruiting
Radiation boost for cervical cancer: SABR vs brachytherapy
This trial compares two types of radiation boost therapy for locally advanced cervical cancer: a newer, precise type called SABR versus the standard brachytherapy. The goal is to see if SABR works as well or better with fewer side effects.
Mexico City, TlalpanAges 18 years+ - NCT07022470RecruitingPhase 2
Comparing 3 vs. 4 brachytherapy sessions for cervical cancer
This trial compares two different schedules of brachytherapy (a type of internal radiation) for cervical cancer. It aims to see if a shorter course of 3 treatments works just as well as the standard 4 treatments, which could mean fewer visits and less discomfort.
Palo Alto, CaliforniaAges 18 years+ - NCT07131956Recruiting
Immune biomarkers in prostate cancer brachytherapy
This study looks at immune system markers in men getting brachytherapy (internal radiation) for prostate cancer. It may help us understand how the body responds to this treatment.
Augsburg, BavariaAges 18 years+ - NCT07152678RecruitingPhase 2
Brachytherapy with radiation and immunotherapy for esophageal cancer
This trial tests combining brachytherapy (a type of internal radiation) with immunotherapy (nivolumab) for people with advanced esophageal cancer that has not fully responded to initial chemoradiation. The goal is to see if this targeted approach can improve outcomes.
Huwei, Yunlin CountyAges 18–85 - NCT07182279RecruitingPhase 1/Phase 2
Internal radiation before prostate surgery for high-risk cancer
This trial tests a treatment approach for newly diagnosed, high-risk prostate cancer. You would receive a short course of internal radiation (high-dose-rate brachytherapy) before surgery to remove your prostate. The goal is to see if this combination is safe and works better than surgery alone.
Houston, TexasAges 40 years+ - NCT07292298RecruitingPhase 2
Rectal cancer brachytherapy after treatment to avoid surgery
This trial tests a special type of internal radiation (brachytherapy) for people with low-lying rectal cancer that did not fully go away after standard chemoradiation and chemotherapy. The goal is to shrink the remaining tumor enough to avoid major surgery like removing the rectum or colostomy.
Aurora, ColoradoAges 18–100 - NCT00913939Recruiting
MRI-guided high-dose-rate treatment for recurrent prostate cancer
This study tests a targeted radiation approach called high-dose-rate (HDR) brachytherapy, guided by MRI, for certain people with recurrent or higher-risk prostate cancer. It may help deliver radiation more precisely, depending on your cancer type and prior treatments.
Toronto, OntarioAges 18 years+ - NCT01913106RecruitingPhase 1/Phase 2
Testing valacyclovir with an added cancer gene in prostate radiation
This Phase 1/2 study tests whether adding a cancer-targeting gene therapy (HSV-tk) and the antiviral medicine valacyclovir to brachytherapy can better treat recurrent prostate cancer in the prostate area. It may help by making cancer cells more vulnerable to the treatment.
Houston, TexasAges Any age - NCT02391051RecruitingPhase 2
Targeted radiation for low-risk prostate cancer
This trial tests a focused form of radiation placed inside the prostate to treat only the cancer area in people with low-risk prostate cancer. It aims to control the cancer while limiting treatment to a smaller area.
ErlangenAges 18 years+ - NCT07468903Recruiting
