BeijingAges 18–75 - NCT05286138Recruiting
Cancer outcomes in people with blood disorders like thalassemia or sickle cell
This study looks at how cancers occur and what they look like in people with certain inherited blood disorders, such as beta-thalassemia, hemoglobin H disease, and sickle cell disease. It may help doctors better understand cancer patterns in these conditions so care can be improved.
CagliariAges 18–100 - NCT04944563Recruiting
Segmentectomy vs lobectomy for small middle-lung lung cancer
This trial compares two types of lung surgery for certain small lung cancers in the middle part of the lung: removing a segment (segmentectomy) versus removing a whole lobe (lobectomy). It aims to see which surgery works better while balancing cancer control and lung function.
Nanjing, JiangsuAges 18–75 - NCT04946773Recruiting
Deep liver testing study for cancer and non-cancer liver disease
This study looks closely at how the liver’s immune system and disease processes work in people with liver problems, including some with suspected or confirmed liver/bile duct cancer. You may also be offered a liver needle sample (FNA) if it’s safe for you.
Oxford, OxfordshireAges 18–75 - NCT04894188Recruiting
Hormone plus radiation before prostate surgery for high-risk cancer
This trial studies giving hormone treatment and radiation before prostate surgery to treat high-risk, locally advanced prostate cancer. It aims to improve cancer control by shrinking or controlling the tumor before removing it.
Douliu City/Huwei Township, Yunlin CountyAges 20–75 - NCT04806295Recruiting
National registry for people with blood cancers
This is a national research registry that collects information from people with blood cancer before, during, and after treatment. It may help researchers better understand care and outcomes and may connect you to future studies.
Rye Brook, New YorkAges 21 years+ - NCT05319483Recruiting
Study of new head and neck cancer patients
This study enrolls adults with a first-time head and neck cancer diagnosis and collects health and treatment information to better understand the disease. It may help clinicians improve care by learning which treatments and patient features matter most.
Pécs, BaranyaAges Any age - NCT05323201RecruitingPhase 1/Phase 2
B7H3 CAR-T therapy for advanced liver cancer
This trial tests an immune therapy made from your own blood cells (CAR-T) to treat advanced, unresectable liver cancer. It’s designed for people whose tumor has a specific marker called B7H3 and who meet blood, organ, and safety requirements.
Xuzhou, JiangsuAges 18–70 - NCT05326295Recruiting
Breast cancer study using tumor cells in blood
This trial checks whether a blood test that looks at tumor cells can help guide treatment for people with breast cancer. If you join, your care team will follow your responses over time to see if this “phenotype surveillance” approach is useful.
Changsha, HunanAges 18–75 - NCT04938986Recruiting
Testing a tumor marker to predict colon cancer relapse risk
This study looks at whether a lab test on your tumor can better predict the chance that non-metastatic colon cancer will come back after surgery. Researchers will compare relapse risk using the Immunoscore® test to help guide follow-up and treatment decisions.
MarseilleAges 18–80 - NCT05342792RecruitingPhase 3
Chemo tablets with or without an immune therapy after cancer treatment
This trial tests whether taking the chemo tablet capecitabine after standard chemoradiation can help prevent cancer from coming back, and whether adding an immune therapy (a PD-1 antibody) improves results. It is for people with high-risk nasopharyngeal (throat) cancer whose main treatment has already finished.
Guangzhou, GuangdongAges 18–65 - NCT05323929Recruiting
Checks how scar depth after stomach tumor removal affects healing
This study looks at early stomach cancer treated with ESD, a procedure to remove the tumor through the stomach lining, and how the depth of the scar relates to healing. It may help doctors predict better outcomes and improve the procedure for suitable patients.
Hangzhou, ZhejiangAges 18–75 - NCT05327517Recruiting
Surgery or chemo-radiation for cervical esophagus cancer
This study compares two ways to treat cervical esophagus squamous cell cancer: surgery alone versus chemo-radiation (chemotherapy plus radiation). It may help find the best approach to control the cancer while keeping side effects manageable.
BeijingAges 18–75 - NCT05314114Recruiting
Skipping underarm surgery for some breast cancers after chemotherapy
This trial studies whether it’s safe to skip removing underarm lymph nodes (axillary surgery) for people with certain breast cancers after they respond to “NACT,” a type of chemotherapy. It also uses planned breast-conserving surgery and whole-breast radiation to see if outcomes stay similar while reducing surgery-related side effects.
Beijing, Beijing MunicipalityAges 18–70 - NCT03753243RecruitingPhase 2
Pembrolizumab and hormone blocker before prostate surgery
This Phase 2 trial studies whether pembrolizumab plus a hormone “androgen axis” blocker taken before prostate surgery can improve outcomes for people with high-risk, non-metastatic prostate cancer. It’s designed for patients who are planning prostate removal with an extended lymph node dissection.
Portland, OregonAges 18 years+ - NCT04666961RecruitingPhase 2
Hormone therapy before surgery for extensive DCIS
This Phase 2 study tests whether taking hormone medicine before surgery can change the surgical plan and outcomes for people with extensive ductal carcinoma in situ (DCIS). It is for estrogen-receptor positive DCIS and aims to see how this “neoadjuvant” approach affects treatment decisions.
AngersAges 40 years+ - NCT02354274Recruiting
New radiation approach for locally advanced lung cancer
This study tests a new way of giving radiation for people with locally advanced non-small cell lung cancer (NSCLC), along with a chemotherapy medicine (navelbine). It may help by improving how well the treatment controls the cancer in the chest while watching for side effects.
AalborgAges 18 years+ - NCT03972956Recruiting
Collecting samples during cancer or surgery visits
This trial looks at collecting (taking) medical samples from people who need surgery for colorectal cancer, stomach (gastric) cancer, or a non-cancer condition. It may help researchers better understand these diseases and improve how treatment is planned.
Wuhan, HubeiAges 18–80 - NCT05347524Recruiting
Blood test study to detect stomach cancer spread in the belly
This study checks whether a blood liquid biopsy test can detect when stomach cancer has spread to the lining of the abdomen (peritoneal metastasis). It compares people with confirmed belly spread to people whose belly lining tests were negative, using blood samples before/around treatment decisions.
Shanghai, Shanghai MunicipalityAges 18–74 - NCT05346510Recruiting
Prone CT and ultrasound to check underarm lymph nodes
This study checks how well CT scans and ultrasound (done while lying face-down) can identify underarm lymph node involvement in people with breast cancer before surgery. If accurate, this may help guide whether additional lymph node surgery is needed.
Shenyang, LiaoningAges 18–70 - NCT05345860Recruiting
Using MRD results to guide extra treatment after breast surgery
This trial checks “MRD” (tiny leftover cancer signals after surgery) to help decide the best additional treatment for early-stage breast cancer. It may help tailor therapy so you get the most useful medicines while avoiding unnecessary treatment.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05354375RecruitingPhase 1
PSMA-targeted CAR-T cell therapy for resistant prostate cancer
This Phase 1 study tests whether lab-made immune cells (CAR-T) that target PSMA can treat prostate cancer that keeps growing despite hormone treatment. It may help people whose disease no longer responds to standard endocrine (hormone-blocking) therapy.
Xuzhou, JiangsuAges 18–75 - NCT05334459Recruiting
Radiation and medicines after surgery for new metastatic breast cancer
This trial looks at giving radiation and anti-cancer medicines after surgery to treat newly diagnosed (de novo) metastatic breast cancer. It may help patients by improving local control of the breast area while also treating cancer throughout the body.
AnkaraAges 18–80 - NCT05037825Recruiting
Study gut microbes with immune therapy in several solid cancers
This trial looks at how the gut microbiome (the bacteria in your digestive system) relates to outcomes when you take standard immune “checkpoint” cancer medicines. If you’re eligible, they’ll collect stool samples while you receive treatment for certain cancers.
