ChandigarhAges 18 years+ - NCT05212454RecruitingPhase 3
Capecitabine added after surgery for high-risk ER-positive breast cancer
This Phase 3 study tests whether adding capecitabine (a chemotherapy pill) after breast cancer surgery can lower the chance the cancer comes back. It targets people with hormone-receptor–positive and HER2-negative breast cancer who are considered “high risk.”
Hanzhou, ZhejiangAges 18–70 - NCT05834764RecruitingPhase 2
Pyrotinib for high-risk HER2-positive early breast cancer
This Phase 2 trial tests pyrotinib, a HER2-targeted cancer medicine, in people with high-risk, HER2-positive breast cancer after surgery. It aims to lower the chance the cancer comes back, especially when standard treatment did not fully clear the tumor.
Nanjing, JiangsuAges 18–75 - 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+ - 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+ - NCT06287541Recruiting
Do you need a second bladder surgery after a negative urine test?
This study looks at whether a second bladder surgery is still needed for people with high-risk bladder cancer who had a negative urine test after their first surgery.
Nanjing, JiangsuAges 18 years+ - NCT06327568Recruiting
Screening for anal cancer and precancer with a new HPV test
This study tests how well a special HPV test (called BD Onclarity™) can find anal cancer or precancer. It is for people at high risk or with known anal abnormalities, and aims to improve early detection.
MilanAges 18 years+ - NCT06385717Recruiting
ESD plus chemoradiotherapy for early esophageal cancer
This study tests whether combining radiation and chemotherapy after endoscopic removal of early-stage esophageal cancer can effectively treat the cancer without needing surgery. It may be an option for people whose cancer was removed with ESD but who want to avoid additional surgery.
Hangzhou, ZhejiangAges 18–75 - NCT05954078RecruitingPhase 3
ctDNA-guided chemotherapy after colon cancer surgery
This trial checks whether a special blood test (ctDNA methylation) can help decide the best chemotherapy after surgery for people at higher risk of colon cancer coming back. It may help spare some patients unnecessary treatment while aiming to improve outcomes for those likely to relapse.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06441110RecruitingPhase 3
BCG instillation for medium- to high-risk bladder cancer
This trial tests whether a specific schedule of BCG (a weakened germ that boosts the immune system) placed directly into the bladder is safe and effective for medium- to high-risk bladder cancer that hasn't grown into the muscle. It aims to see if adjusting the standard BCG course can work better for people with a PD-L1-positive tumor.
Fuzhou, FujianAges 18–75 - NCT06455124RecruitingPhase 2
Short radiation and chemo-immunotherapy for early rectal cancer after local surgery
This trial tests a combination of short-course radiation, chemotherapy (CapeOx), and an immunotherapy drug (PD-1 inhibitor) for people with early-stage rectal cancer who have had a local excision but are at high risk of the cancer coming back. The goal is to avoid more extensive surgery while still effectively treating the cancer.
ShanghaiAges 18–75 - NCT07838207Recruiting
Molecular markers and outcomes in early-stage endometrial cancer
This study looks at women with certain high-risk types of endometrial cancer that have not spread into the muscle wall of the uterus. It aims to understand how these cancers behave and whether lymph node testing is needed, which could help guide treatment decisions.
Barcelona, BarcelonaAges 18 years+ - NCT06461793RecruitingPhase 2
Higher dose radiation with hormone therapy for high-risk prostate cancer
This trial tests a higher dose of radiation given in fewer sessions (hypofractionated) combined with hormone therapy for men with high-risk prostate cancer that has not spread. A gel spacer called SpaceOAR is used to protect the rectum. The goal is to see if this approach is safe and effective.
SeoulAges 20 years+ - NCT07820423Recruiting
AI tool predicts high-risk lung cancer linked to air-filled spaces
This study uses artificial intelligence to examine CT scans and predict whether lung cancer containing air-filled spaces is aggressive. It may help doctors tailor treatment after surgery.
Changsha, HunanAges 18 years+ - NCT06378242RecruitingPhase 1/Phase 2
Testing a bladder cancer drug for high-risk NMIBC patients
This trial tests a drug called Disitamab Vedotin, given directly into the bladder, for a type of early bladder cancer (high-risk NMIBC) that has a protein called HER2. It aims to see if this treatment can help avoid more radical surgery.
Guangzhou, GuangdongAges 18–75 - NCT07801664RecruitingPhase 2
Short course hormone therapy for prostate cancer
This trial tests a short course of hormone therapy (androgen deprivation therapy) for men with a certain type of prostate cancer that is considered high-risk. The goal is to see if a shorter treatment period can still control the cancer while reducing side effects.
New York, New YorkAges 18 years+ - NCT06509724RecruitingPhase 3
