ShanghaiAges Any age - NCT04997837RecruitingPhase 3
Adjuvant chemo with or without PD-1 for stomach cancer after surgery
This Phase 3 trial studies whether adding an immune medicine called PD-1 (given as an “inhibitor”) to standard chemotherapy and chemoradiation after stomach/GEJ cancer surgery can lower the risk of cancer coming back. You may qualify if you’ve had surgery removing the tumor and lymph nodes showed higher-risk disease.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05010031RecruitingPhase 2
Lower-dose radiation for metastatic cancer with an ATM mutation
This trial tests whether giving a lower dose of radiation can help control metastatic tumors that carry a specific genetic change in the ATM gene. It may reduce side effects by using less radiation, while still aiming to keep the tumor under control.
Basking Ridge, New JerseyAges 18 years+ - NCT05023265Recruiting
Study quality of life after SBRT for kidney cancer
This trial studies how well people do—especially their quality of life—after SBRT radiation for primary kidney cancer that can’t be removed with surgery. It may help doctors understand which patients benefit most and what side effects to expect.
Toronto, OntarioAges 18 years+ - NCT05030207Recruiting
Test a new CT scan method for lung cancer radiation planning
This study tests whether a real-time, breathing-adapted CT scan (called 4DCT) can be done safely and work well for planning radiation treatment for lung cancer. It may help make radiation planning more accurate while checking if the scan process is practical for patients.
Blacktown, New South WalesAges 18 years+ - NCT05032768Recruiting
Study links between skin bacteria and radiation skin reactions
This study looks at how changes in the skin’s normal bacteria (microbiome) relate to getting redness, irritation, or rash after breast radiation. It may help doctors predict who is more likely to have skin side effects after reconstruction and radiation.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05052957RecruitingPhase 2
Autologous stem cell rescue for newly diagnosed brain tumor
This trial tests giving a patient’s own stem cells back to help the bone marrow recover after treatment for newly diagnosed glioblastoma or gliosarcoma. It may help reduce blood-count problems so treatment can be given more safely.
Cleveland, OhioAges 18–75 - NCT05055635RecruitingPhase 2
Proton radiation for anal cancer that came back after prior treatment
This trial studies a focused type of proton radiation (“pencil beam”) to treat anal cancer that has returned after you previously had radiation. It may help by aiming treatment more precisely and giving another chance at cure when doctors think it can still be treated.
Aarhus N, AarhusAges 18 years+ - NCT05061342Recruiting
Cancer or healthy volunteers share health and imaging survey data
This study collects information about how cancer care affects daily life, treatment side effects, and quality of life, and it stores imaging and related data for future research. You might be able to take part if you’re scheduled for treatment at the center (or you’re a healthy volunteer) and can complete the questionnaires.
Shenzhen, GuangdongAges 18 years+ - NCT05076500Recruiting
How radiotherapy changes a tumor’s immune response
This study looks at how a tumor’s immune system responds when you receive radiotherapy. It involves taking a planned pre-treatment biopsy so researchers can study immune and tumor changes and see if radiotherapy affects them.
ManchesterAges 18 years+ - NCT05076942RecruitingPhase 2
Study of sentinel lymph nodes in vulvar cancer
This Phase 2 study looks at how vulvar squamous cell cancer (SCC) spreads to the sentinel lymph node, and how findings may guide treatment. It focuses on specific early-stage tumor features and requires that cancer is found in the sentinel lymph node.
Orange, CaliforniaAges 18 years+ - NCT05082961Recruiting
Blood immune markers and brain radiation after head/neck surgery
This study looks at immune system signals in your blood during and after postoperative radiation therapy for certain head and neck cancers involving the brain or skull base. Researchers want to see whether these “immune markers” relate to treatment response or side effects.
CaenAges 18 years+ - NCT05147844RecruitingPhase 2
Toripalimab plus radiation for limited-spread nose cancer
This Phase 2 trial studies whether adding toripalimab (an immune therapy) to radiation can control nasopharyngeal cancer that has spread only to a few places. It may help by boosting the immune system while the radiation treats the tumor sites.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05167994RecruitingPhase 2
Pre-surgery radiation plus an anti-cancer drug for soft tissue sarcoma
This Phase 2 trial tests whether giving radiation before surgery, along with anlotinib and penpulimab, can improve treatment for localized soft tissue sarcoma. It may help shrink or control the tumor before conservative surgery.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05179447Recruiting
Study testing added treatment after endometrial cancer surgery
This trial looks at how to guide follow-up (adjuvant) treatment after surgery for certain early-stage, higher-risk endometrial cancer. It may help by tailoring care based on patient and tumor details to lower the chance of the cancer coming back.
Wuhan, HubeiAges 18–75 - NCT05184790Recruiting
Using imaging during radiation therapy to improve AI planning
This study tests how well an artificial intelligence system can use special X-ray images taken during certain radiation treatments to improve care. You may qualify if you’re having radiation for specific conditions and your treatment center uses the required imaging steps.
Saint Leonards, New South WalesAges 18 years+ - NCT05187091RecruitingPhase 3
Radiation plan that tries to protect swallowing organs
This Phase 3 study compares a standard radiation approach versus a modified approach designed to spare key swallowing and aspiration (choking) related areas and one salivary gland. It may help reduce treatment side effects that affect swallowing and quality of life for certain head and neck cancer patients.
Jhajjar, HaryanaAges 18–70 - NCT05191940Recruiting
Radiation for advanced pancreatic cancer you can’t remove by surgery
This trial studies how well radiation therapy works for pancreatic cancer that is locally advanced (near important blood vessels) and cannot be removed with surgery. It may help shrink or control the cancer when surgery isn’t an option.
Wiener Neustadt, Lower AustriaAges 18 years+ - NCT05203250Recruiting
Registry for people treated with heavy particles at CNAO
This registry collects information from people who received heavy particle treatments at the CNAO center. It helps researchers understand outcomes over time, as long as you can understand the study and agree in writing.
