Nanchang, JiangxiAges 18–75 - NCT03315546RecruitingPhase 1/Phase 2
Breathing-hold radiotherapy for children with chest or belly tumors
This early-phase trial tests a radiotherapy technique that uses deep, coached breaths and short breath-holds to help protect healthy organs during treatment. It may help children who need radiation for certain tumors in the chest or belly area.
Copenhagen, DanmarkAges 5–17 - NCT04448522RecruitingPhase 3
Lower-dose radiotherapy for EBV-responsive nasopharyngeal cancer
This Phase 3 study tests whether giving a reduced amount of radiotherapy can work as well as the standard dose for certain people with stage II–III nasopharyngeal cancer who respond well after initial chemotherapy. It’s designed for patients whose cancer markers improve after 3 chemotherapy cycles, to potentially reduce treatment side effects while keeping cancer control.
Guangzhou, GuangdongAges 18–70 - NCT04695782RecruitingPhase 2
Proton radiation for recurrent rectal cancer in the pelvis
This trial studies “pencil beam” proton radiation for rectal cancer that has come back in the pelvis after you already had radiation. It aims to control the recurrence while trying to limit harm to nearby organs.
AarhusAges 18 years+ - NCT03541928RecruitingPhase 2
Gene therapy with standard treatment for high-risk prostate cancer
This trial combines gene therapy with hormone therapy, radiation, and possibly surgery to treat high-risk prostate cancer. It aims to improve outcomes by adding gene therapy to standard treatments and will require additional biopsies.
Houston, TexasAges 18 years+ - NCT03961776Recruiting
MRI to monitor treatment response in rectal cancer
This trial tests whether an MRI scan done during chemoradiation can help doctors track how rectal cancer treatment is working. It may improve how they measure response early so treatment planning can be better tailored.
Los Angeles, CaliforniaAges 18 years+ - NCT02838602Recruiting
Carbon beam radiation vs standard radiation for resistant tumors
This study compares carbon beam radiation with standard radiation for tumors that are less likely to respond to usual radiation. It aims to see whether carbon beams can improve control of the cancer while keeping side effects manageable.
AmiensAges 18 years+ - NCT04519905Recruiting
Testing two ways of radiation in older esophagus cancer patients
This study compares a planned radiation approach given at the same time as other treatment for older adults with esophageal squamous cell carcinoma. It may help find a safer and more effective radiation schedule for people who are fit enough for treatment.
Nanjing, JiangsuAges 76 years+ - NCT02102477Recruiting
Surgery or radiation for prostate cancer in the pelvis
This trial compares surgery versus radiation for men with locally advanced prostate cancer that has not spread to distant sites. It aims to see which treatment works better and is easier to manage for people like you.
AalborgAges 18–75 - NCT05334459Recruiting
Radiation and medicines after surgery for new metastatic breast cancer
This trial looks at giving radiation and anti-cancer medicines after surgery to treat newly diagnosed (de novo) metastatic breast cancer. It may help patients by improving local control of the breast area while also treating cancer throughout the body.
AnkaraAges 18–80 - NCT05378919RecruitingPhase 2
Testing new pre-surgery treatment for locally advanced rectal cancer
This Phase 2 trial compares a pre-surgery (neoadjuvant) treatment plan versus the standard plan for people with stage II–III rectal cancer. The goal is to see which approach works better and is safe before surgery.
KaunasAges 18 years+ - NCT03829553RecruitingPhase 3
Radiation to breast lymph nodes versus standard breast cancer care
This Phase 3 trial tests whether a shorter, more focused radiation treatment to the regional lymph nodes works as well as the current standard approach for certain breast cancers. It may help patients by potentially improving treatment efficiency while keeping cancer control effective.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05352321Recruiting
Surgery plus targeted chemoradiation versus standard chemoradiation
This trial compares two treatment plans for newly diagnosed, operable nasopharyngeal cancer: adding surgery plus targeted chemoradiation versus standard chemoradiation alone. It aims to see whether the surgery-based plan improves control of the cancer and related outcomes.
Guangzhou, GuangdongAges 18–70 - NCT05603078Recruiting
Breast cancer surgery with a tumor-bed boost and standard radiation
This study looks at whether adding extra targeted radiation to the tumor area before breast-conserving surgery, then using modern breast surgery techniques and whole-breast radiation afterward, improves outcomes for early-stage breast cancer. You may be offered a treatment plan designed to better treat the area where the tumor was removed.
Beijing, Beijing MunicipalityAges Up to 55 years - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT05692674RecruitingPhase 2
Proton radiation after breast surgery with implant reconstruction
This trial studies a type of radiation made with proton beams given after mastectomy and implant reconstruction to lower breast cancer coming back. It’s for people who need additional (adjuvant) radiation and have not had prior radiation to the chest or breast.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT05354596Recruiting
SBRT radiation trial for central lung tumors
This trial studies a focused, high-dose radiation treatment called SBRT for lung tumors that are hard to operate on, including very central tumors near major airways or organs. It may help people control tumor growth while limiting radiation exposure to nearby critical structures.
AalborgAges 18 years+ - NCT05762900RecruitingPhase 2
Shorter breast radiation after surgery for low-risk breast cancer
This Phase 2 trial tests a shorter, focused radiation treatment after breast surgery, either alone or with an extra targeted boost. It’s for people with low-risk breast cancer and no spread to distant organs, aiming to keep results while reducing treatment time and side effects.
BeijingAges 35 years+ - NCT05804916RecruitingPhase 2/Phase 3
Tracking-guided radiation for left breast after surgery
This trial tests a radiation planning and monitoring approach that uses surface tracking and breathing control to deliver large-area radiation more accurately for left breast cancer. It may help improve how consistently treatment is delivered while accounting for chest movement.
Beijing, Beijing MunicipalityAges 18–70 - NCT04019548RecruitingPhase 3
Test swallowing and quality of life during chemo-radiation for throat cancer
This study looks at how well people swallow and how their quality of life changes during standard chemo-radiation for newly diagnosed throat (oropharyngeal) cancer. The goal is to better understand swallowing side effects so care can improve.
BrusselsAges 18 years+ - NCT05854823Recruiting
Reduced radiation after surgery for advanced head and neck cancer
This trial looks at whether giving less (de-escalated) radiation after surgery is as effective and safer for people with locally advanced head and neck squamous cell carcinoma who had a strong response to treatment before surgery. If you had no remaining cancer or only very small amounts of cancer left in the surgical specimen, this approach may help reduce side effects while keeping control of the disease.
Zhuhai, GuangdongAges 18–70 - NCT02275286RecruitingPhase 1/Phase 2
Trabectedin plus radiation for select soft tissue sarcomas
This trial studies whether adding a chemotherapy medicine called trabectedin to targeted radiation can help control certain soft tissue sarcomas. It focuses on specific cancer types and locations, aiming to shrink tumors while keeping radiation safe for nearby healthy organs.
