Recruiting studies
- NCT07371234RecruitingPhase 2
Low-dose radiation and immunotherapy before surgery for head and neck cancer

GuangdongAges 18–75 - NCT04989647RecruitingPhase 3
Stage IB1 to IIA cervical cancer surgery with possible radiation
This Phase 3 trial studies how best to treat intermediate-risk cervical cancer using radical surgery, with or without additional radiation after surgery. It may help find which approach lowers the chance the cancer comes back for patients with certain tumor risk features.
PragueAges 18–85 - NCT06272214RecruitingPhase 2
Adjuvant radiotherapy for esophageal cancer after immunotherapy
This trial tests if adding radiation therapy after surgery improves outcomes for people with esophageal squamous cell cancer who received immunotherapy and chemotherapy before surgery but did not achieve a complete response. It aims to see if this approach can lower the chance of the cancer coming back.
Hangzhou, ZhejiangAges 18–75 - NCT06826885Recruiting
Comparing two types of radiation for breast cancer
This trial is testing how well two different radiation techniques, IMPT and IMRT, work for treating breast cancer. It aims to see which one is safer and more effective, so you might benefit from a potentially better treatment approach.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06205472RecruitingPhase 2
Radiation after liver cancer surgery with narrow margins
This trial tests whether adding a type of radiation (SIB radiotherapy) after liver cancer surgery can improve outcomes for patients whose tumors were removed with very narrow clear margins (less than 1 cm). It may help reduce the chance of cancer coming back in the remaining liver.
BeijingAges 18 years+ - NCT07524452RecruitingPhase 3
Becotatug vedotin plus immunotherapy for head and neck cancer
This trial tests a new combination of two drugs—becotatug vedotin (a targeted therapy) and a PD-1 inhibitor (an immunotherapy)—given before surgery to treat advanced head and neck squamous cell carcinoma. The goal is to shrink tumors and improve surgical outcomes for patients with specific cancer markers.
Zhuhai, GuangdongAges 18–75 - NCT04902937Recruiting
Testing how added radiation may work by immune and tumor markers
This study looks at people with non-metastatic invasive breast cancer who are getting curative breast surgery followed by planned radiation (sometimes with other anti-cancer medicines). Researchers want to understand whether a patient’s age and certain immune/tumor blood features can predict how well radiation helps.
JenaAges 18 years+ - NCT07186621RecruitingPhase 3
Testing immunotherapy or chemoembolization after liver cancer surgery
This trial compares two treatments after liver cancer surgery to see which better prevents the cancer from coming back. You may be eligible if your surgery had a narrow margin and you have certain risk factors, like a tumor over 5 cm or high AFP levels.
BeijingAges 18–80 - NCT06524167Recruiting
Radiation therapy after surgery for advanced thyroid cancer
This study looks at whether adding radiation therapy after surgery can help people with thyroid cancer that is at high risk of coming back. It includes different types of thyroid cancer, like differentiated and medullary types.
ShanghaiAges 14–80 - NCT02633553Recruiting
Radiation after surgery for stage II or III thymoma
This trial looks at adding radiation after a complete surgery to remove a thymoma (a tumor from the thymus) at stages II or III. It may help lower the chance the cancer comes back by treating leftover microscopic disease after surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07762885RecruitingPhase 3
Comparing skipping radiation after surgery for early-stage DCIS
This trial compares skipping radiation therapy after breast-conserving surgery for low- or intermediate-risk ductal carcinoma in situ (DCIS) – a very early, non-invasive breast cancer. It aims to see if omitting radiation is as effective as standard treatment while reducing side effects.
ShanghaiAges 40 years+ - NCT07779109Recruiting
Shorter radiation course for endometrial cancer after surgery
This study tests a shorter, more intense course of radiation therapy after surgery for endometrial cancer. It aims to see if it is safe and works as well as standard radiation, while possibly reducing treatment time.
Zaragoza, ZaragozaAges 18–110 - NCT06914440RecruitingPhase 2
Radiation and immunotherapy before surgery for HR+/HER2- breast cancer
This trial is testing a new treatment approach for patients with a certain type of breast cancer (HR+/HER2-). It combines radiation therapy with chemotherapy and an immunotherapy drug before the patient's main surgery, to see if it can shrink or eliminate the tumor more effectively.
Xi'an, Shannxi ProvinceAges 18–75 - NCT05277688RecruitingPhase 3
Radiation alone versus added chemotherapy after cervical cancer surgery
This trial compares standard radiation to radiation plus chemotherapy after surgery for early-stage cervical cancer. It aims to lower the chance the cancer comes back in patients considered higher risk based on their surgical pathology.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06798922RecruitingPhase 3
Flap-sparing radiation for mouth cancer after reconstructive surgery
This trial tests a special radiation technique for people who have had reconstructive surgery for oral cavity cancer. The goal is to see if we can spare the flap (the rebuilt tissue) from high radiation doses to improve healing and quality of life.
AmiensAges 18 years+ - NCT07125755RecruitingPhase 3
Comparing Chemo plus Radiation vs. Radiation Alone for Head and Neck Cancer
This trial tests whether adding chemotherapy to radiation therapy after surgery can help prevent head and neck cancer from coming back. It is for people who have certain risk factors after their surgery but no signs of cancer spread.
Guangzhou, GuangdongAges 18–70 - NCT07116213Recruiting
Shorter radiation after surgery for high-risk endometrial cancer
This trial studies a new type of radiation therapy (called online adaptive radiotherapy) given in shorter, higher daily doses after surgery for high-risk endometrial cancer. The goal is to see if this approach is safe and effective for reducing side effects while still controlling the cancer.
Beijing, Beijing MunicipalityAges 18–70 - NCT06335693Recruiting
Short-course radiation after prostate surgery
This trial tests a shorter course of radiation therapy (hypofractionated radiotherapy) for men who have already had their prostate removed and still have signs of cancer (like rising PSA). The goal is to see if this can help prevent the cancer from coming back.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06558981RecruitingPhase 3
Radiation therapy after thyroid surgery for high-risk cancer
This trial is testing whether giving radiation therapy after thyroid surgery can help destroy any leftover cancer cells in people with high-risk differentiated thyroid cancer. It is for those who had surgery but some cancer was still left behind.
ShanghaiAges 14–80 - NCT04282122Recruiting
Personalized radiation plan for older women with early breast cancer
This trial uses individual measures of how sensitive your body’s tissues are to radiation to guide after-surgery breast radiation treatment. It aims to keep treatment safe and effective while tailoring the plan to each person.
Montpellier, OccAges 65 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+ - 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+ - NCT05640999RecruitingPhase 2
Trial for early uterine cancer with POLE mutation after surgery
This Phase 2 trial studies an added (adjuvant) treatment for early-stage uterine cancer that has a specific genetic change called POLE mutation and does not have a p53 abnormal pattern. The goal is to lower the risk of the cancer coming back after surgery.
Anchorage, AlaskaAges 18 years+ - NCT06692556RecruitingPhase 3
Radiation vs monitoring for high-risk skin cancer
This trial compares two strategies after surgery for a type of skin cancer (cutaneous squamous cell carcinoma) that has a high chance of coming back. One strategy gives radiation therapy to the area, while the other just watches and checks for any signs of recurrence. The goal is to see if radiation can prevent the cancer from returning.
