Liver tumor treatment study for large tumors
This study tests a targeted radiation treatment called Y90 for liver tumors that are too large for standard approaches. It aims to see how well the treatment works for people with primary or secondary liver cancers that mainly affect the liver and have at least one tumor bigger than 5 cm.

Nijmegen, GelderlandAges 18 years+ - NCT06259149Recruiting
Timing of blood clot prevention after colorectal cancer surgery
This study looks at when to start blood thinners after surgery for colorectal cancer. The goal is to find the safest time to prevent blood clots without increasing bleeding risk.
Shanghai, Shanghai MunicipalityAges 18–110 - NCT06259279Recruiting
High impact training for prostate cancer with bone spread
This trial tests whether high impact exercise can help men with prostate cancer that has spread to their bones. You may qualify if you have bone metastases and are on hormone therapy.
Herlev, HerlevAges 18 years+ - NCT06259162Recruiting
LAG3 study in triple-negative breast cancer
This trial is studying a protein called LAG3 in triple-negative breast cancer. It is for people who will receive chemotherapy before surgery to see if LAG3 levels affect how well the treatment works.
SeoulAges Any age - NCT06259552RecruitingPhase 1
Study of SPX-303 for advanced solid tumors
This trial tests a new drug called SPX-303, which is designed to help your immune system fight cancer cells. It is for people with advanced solid tumors that have not responded to other treatments.
Phoenix, ArizonaAges 18 years+ - NCT06259513Recruiting
Skipping armpit surgery for breast cancer patients
This trial tests whether it's safe to skip armpit surgery in older women with small, low-risk breast cancers. If you qualify, you would have a mastectomy without removing lymph nodes from your armpit.
SingaporeAges 21–80 - NCT06259721RecruitingPhase 2
New drug combo for advanced nasopharyngeal cancer after platinum failure
This trial tests a combination of three drugs—an anti-PD1 immunotherapy, nimotuzumab (targets EGFR), and capecitabine (chemotherapy)—for people whose nasopharyngeal cancer has returned or spread and no longer responds to platinum-based chemotherapy. The goal is to see if this combination can help when standard treatment stops working.
Nanchang, JiangxiAges 18–70 - NCT06259929RecruitingPhase 2
Neoadjuvant abemaciclib and giredestrant for early breast cancer
This trial tests a combination of two oral medications (abemaciclib and giredestrant) given before surgery to women with a common type of early breast cancer (hormone receptor-positive, HER2-negative). The goal is to see if this treatment can shrink the tumor before surgery.
Catania, CataniaAges 18 years+ - NCT06260033RecruitingPhase 2
Radiation Therapy for Oligoprogressive ER+ Breast Cancer
This trial tests whether a precise radiation treatment (SBRT) can target a few growing spots of estrogen receptor-positive breast cancer that has spread to other parts of the body. It also uses a special PET scan (FES PET/CT) to see how well the cancer responds. The goal is to slow down the cancer and delay the need for stronger treatments.
Duarte, CaliforniaAges 18 years+ - NCT06260111Recruiting
Laser therapy for mouth sores during stem cell transplant
This study tests whether a special light therapy (photobiomodulation) can reduce painful mouth sores and help you eat, drink, and speak better during a stem cell transplant. It is for adults with blood cancers who are having a stem cell transplant.
Santiago, Santiago MetropolitanAges 18–65 - NCT06260358Recruiting
Cervical cancer MRI report study
This study tests a new structured way of reporting MRI scans for cervical cancer patients. It may help doctors better understand and stage the disease.
RomeAges 18 years+ - NCT06260410Recruiting
Lu-PSMA prostate cancer data study
This study collects information (like scans and blood tests) from men with prostate cancer who are about to start Lu-PSMA therapy. The goal is to track how the cancer responds and learn more about its features during treatment.
Rotterdam, South HollandAges 18 years+ - NCT06260943Recruiting
Navigating liver cancer care: a study for patients, caregivers, and providers
This study aims to improve how patients with liver cancer (hepatocellular carcinoma) get the support and information they need. Researchers will interview patients, caregivers, and healthcare providers to find better ways to navigate care.
Miami, FloridaAges 18 years+ - NCT06261125RecruitingPhase 2
SBRT plus immunotherapy and targeted drug for liver cancer
This trial tests a combination of radiation (SBRT), an immunotherapy drug (PD-L1 inhibitor), and a targeted therapy (lenvatinib) for people with liver cancer that has spread to abdominal lymph nodes. It may be an option if you haven't taken certain immunotherapies before or if your cancer progressed after them.
Guangzhou, GuangdongAges 18–75 - NCT06261918Recruiting
Breast cancer study: linking metabolism to tumor behavior
This study looks at how your metabolism (things like blood sugar and cholesterol) might be linked to tumor genes and growth in people with breast cancer. The goal is to find new ways to treat the disease based on your metabolic profile. You may be eligible if you have locally advanced breast cancer (Stage II–III) and are willing to share your medical records.
RomaAges 18 years+ - NCT06261814RecruitingPhase 2

It is for people with advanced non-small cell lung cancer that does not have certain gene changes and has high-risk tumors in the chest.
Rochester, New YorkAges 18 years+ - NCT06262386Recruiting
