Taizhou, ZhejiangAges 18–80 - NCT05717790Recruiting
Nimotuzumab with chemo and radiation for advanced nose cancer
This trial tests whether adding nimotuzumab (an anti-EGFR antibody) to standard chemotherapy and radiation can improve outcomes for people with advanced nasopharyngeal carcinoma. It may help the cancer respond better and control it more effectively after treatment.
Baise City, GuangxiAges 18–70 - NCT05800054Recruiting
Nutrition support program for people with esophageal cancer
This trial tests whether an “NST whole-course” nutrition management plan can improve nutrition status and reduce side effects during treatment for stage II–III esophageal cancer. It may help you stay stronger and tolerate cancer therapy better by carefully monitoring and adjusting nutrition.
Nanjing, JiangsuAges 18–75 - NCT04861415Recruiting
Testing a shorter radiation plan versus standard prostate radiation
This study compares two ways of giving radiation to the prostate, including a “boost” using a special internal radiation treatment. It’s meant to see which radiation schedule works better and is safer for certain prostate cancer patients.
Toronto, OntarioAges 18 years+ - NCT04805255Recruiting
Study brain-targeted radiation for limited brain metastases
This study looks at people with a small number of brain metastases who are treated with a focused, staged form of radiation after surgery or to treat the cancer. It may help doctors better understand how well this approach works and who benefits most.
TaoyuanAges 18–84 - NCT02504788Recruiting
Protect the brain’s memory area during whole-brain radiation
This study tests whether avoiding the hippocampus (a part of the brain important for memory) during whole-brain radiotherapy can slow down thinking and memory decline. It may help some people preserve neurocognitive function while still treating brain metastases.
TaoyuanAges 18–84 - NCT04654338RecruitingPhase 2/Phase 3
Two types of targeted radiation for favorable prostate cancer
This trial tests whether two “ablative” (high-dose, focused) radiation treatments can work well for men with favorable-risk prostate cancer. It looks at whether the treatments are practical and safe, especially for urinary side effects.
Toronto, OntarioAges Any age - NCT03908502Recruiting
Study for nervous system problems after radiation therapy
This study looks at nervous system complications that can happen after receiving radiation therapy. You may be invited if you’ve had radiotherapy and can safely consent to participate.
Guangzhou, GuangdongAges birth+ - 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+ - NCT05976412Recruiting
Radiation to lymph nodes after surgery for higher-risk breast cancer
This trial looks at whether adding targeted radiation to lymph nodes after breast surgery can lower the chance of breast cancer coming back in people with higher-risk, node-negative disease. If you qualify, you may get a planned radiation approach designed for prevention, not treatment of spread.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05994170Recruiting
Lower radiation dose to tumor area for early nasopharyngeal cancer
This trial studies whether lowering the radiation dose to a smaller area around the tumor is safe and effective for people with newly diagnosed nasopharyngeal cancer that has not spread. It may reduce side effects while still curing the cancer.
Zhongshan, GuangdongAges 18–70 - NCT06037902Recruiting
CPAP during radiation for esophageal cancer
This study tests whether using a CPAP mask (which gently pushes air into your airways) during radiation therapy makes treatment safer and more effective for esophageal cancer. It is for adults who are planning radiation and can tolerate wearing the mask.
Ramat GanAges 18 years+ - NCT03534713RecruitingPhase 3
Cervical cancer treatment plan after lymph node spread
This trial tests a specific chemotherapy start (induction) followed by standard treatment for cervical cancer that has spread to lymph nodes near the aorta. It may help improve cancer control compared with standard timing/approach.
BordeauxAges 18 years+ - NCT06055517Recruiting
Re-irradiation with low-dose pulses for recurrent glioma
This trial tests a new way to deliver radiation therapy for people whose brain tumor (glioma) has come back after earlier treatment. Instead of standard radiation, it uses very low doses given in pulses, which may be safer for patients who have already had radiation to the head.
Aviano, PordenoneAges 18 years+ - NCT05724004Recruiting
Alectinib then targeted radiation for ALK-positive lung cancer
This trial tests giving alectinib first, then adding targeted radiation to remaining spots of cancer in people with ALK-rearranged advanced non-small cell lung cancer. It aims to control the cancer after an initial response and help keep disease from progressing.
StockholmAges 20 years+ - NCT06102837Recruiting
Tumor vaccine study for brain surgery patients
This study tests whether a tumor vaccine made from your own surgery tissue can help treat solid tumors, specifically gliomas (brain tumors). It is open to patients having brain surgery at Huashan Hospital, including those with non-tumor conditions like stroke or injury, as long as enough tissue is available.
Shanghai, Shanghai MunicipalityAges Any age - NCT06116019Recruiting
Online adaptive radiotherapy for cancer patients
This trial tests a new radiation therapy machine that adjusts the radiation plan in real-time based on changes in your body. It may help make treatment more precise and reduce side effects.
BerlinAges 18 years+ - NCT06120387Recruiting
Radiation after kidney-sparing surgery for high-risk ureteral cancer
This trial tests whether adding radiation therapy after surgery that removes only part of the ureter or the entire kidney and ureter helps prevent cancer from coming back in patients who have high-risk features like aggressive cell type or deep tumor invasion.
BeijingAges 18 years+ - NCT06122493RecruitingPhase 2
