- NCT04136782RecruitingPhase 4
Tests two chemo drug combinations for triple-negative breast cancer
This Phase 4 trial compares two chemotherapy combinations to treat stage II–III triple-negative breast cancer. It looks for which regimen works better and is tolerated in people with measurable tumors and good overall health.
Harbin, HeilongjiangAges 18–70 - NCT04376866RecruitingPhase 3
Immunotherapy for repeat nasopharyngeal cancer after it returns
This trial studies toripalimab (an immunotherapy that helps your immune system attack cancer) for nasopharyngeal cancer that has come back locally. It may help shrink or control the returning tumor and improve outcomes for people who meet the safety and lab requirements.
Nanning, GuangxiAges 18–65 - NCT04137653RecruitingPhase 3
New pre-surgery drug choice for triple-negative breast cancer
This trial tests which chemotherapy drug works better before surgery (neoadjuvant therapy) for triple-negative breast cancer that has spread to underarm lymph nodes. It compares two forms of paclitaxel given by random assignment to see which option may shrink the tumor more effectively and improve outcomes.
Shenyang, LiaoningAges 18–70 - NCT04700332RecruitingPhase 2
Test of PyL PET/CT for high-risk or returning prostate cancer
This Phase 2 study checks how well a scan called PyL PET/CT can help find prostate cancer that is high-risk or has come back by blood test. The goal is to improve how doctors detect spread and guide the next treatment steps.
Irvine, CaliforniaAges 18 years+ - NCT04476485Recruiting
Predicting breast cancer recurrence after extended hormone therapy
This trial looks at factors that may predict whether hormone receptor–positive breast cancer will come back after you’ve already completed 5 years of hormone (endocrine) therapy. It may help identify who benefits most from longer treatment and follow-up.
Harbin, HeilongjiangAges 18–70 - NCT04146077Recruiting
Active monitoring for low-risk prostate cancer
This study tests whether watching low-risk prostate cancer closely (instead of treating right away) is safe. It may help some people avoid early treatments and their side effects while still keeping a close eye on the cancer.
MoscowAges 50–75 - NCT03335644Recruiting
Internet-based health study for people 15 and older
This study gathers health information through an online program. It may help researchers understand how diet and lifestyle affect health over time.
Bobigny, Seine Saint DenisAges 15 years+ - NCT04231006Recruiting
High-dose salvage radiation for prostate cancer that came back locally
This trial studies high-dose radiation (HDR) given after prostate cancer returns only in the prostate/seminal vesicles. It may help by trying to control the cancer when it has not spread elsewhere, using targeted treatment based on MRI and biopsy proof.
Aarhus, Region MidtAges 18 years+ - NCT04022109Recruiting
Check gastric cancer using breath chemical signals
This study looks at chemical signals in your breath to help screen for or understand gastric (stomach) cancer. It may help doctors improve earlier detection, or better sort out who may need further tests.
São PauloAges 18 years+ - NCT03989323Recruiting
Register to track cancer immune therapy and side effects
This study sets up a real-world patient database to follow people starting cancer immunotherapy and record immune-related side effects. You may help doctors better understand who gets these side effects and how they change over time.
BronAges 18 years+ - NCT02073500Recruiting
Study of treatments and models for cancer in the belly lining
This study looks at how cancers that spread along the belly lining (“peritoneal surface malignancies”) behave and how different treatment strategies may work. It may help improve how doctors select and test treatments for people who are candidates for CRS-HIPEC, a specific cancer surgery approach.
OsloAges 18 years+ - NCT04261829Recruiting
Full method for breast reconstruction after mastectomy
This trial tests a “full breast reconstruction” approach for people who are planning or have had a breast removal (mastectomy). It may help improve how reconstruction is done and whether you can use the external expansion device as part of the process.
Maastricht, LimburgAges 18 years+ - NCT04060706Recruiting
Testing new computer tools for radiation treatment planning
This study tests how well new computer methods (called algorithms and machine learning) can support radiation therapy decisions. You might benefit by helping improve how radiation is planned and checked, especially for cancers treated with curative-intent therapy.
Cambridge, CambridgeshireAges 18 years+ - NCT04993014RecruitingPhase 2
De-escalating treatment after HER2-positive breast cancer responds
This study looks at whether some people with HER2-positive breast cancer can safely receive less (de-escalated) treatment after they finish chemotherapy plus HER2-targeted drugs before surgery. It specifically focuses on people whose cancer shows a complete response on the surgery pathology report.
São PauloAges 18 years+ - NCT04989985RecruitingPhase 2
SOX chemotherapy plus immunotherapy for junction stomach-esophagus cancer
This trial studies whether adding an immunotherapy drug (sintilimab) to standard chemotherapy (S-1 and oxaliplatin) can better treat locally advanced cancer at the junction of the esophagus and stomach. It may help shrink the tumor and control the cancer before or around surgery.
Guangzhou, GuangdongAges 18–75 - NCT04997837RecruitingPhase 3
Adjuvant chemo with or without PD-1 for stomach cancer after surgery
This Phase 3 trial studies whether adding an immune medicine called PD-1 (given as an “inhibitor”) to standard chemotherapy and chemoradiation after stomach/GEJ cancer surgery can lower the risk of cancer coming back. You may qualify if you’ve had surgery removing the tumor and lymph nodes showed higher-risk disease.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04996732Recruiting
Long-term follow-up study for people treated for cancer
This study looks at how people who have finished treatment for cancer are doing over the long term. It uses information from a cancer center registry to understand survivorship and outcomes after surgery and/or other treatments.
ShanghaiAges Any age - NCT05025098RecruitingPhase 2
Targeted treatment versus standard care for older blood cancer patients
This Phase 2 trial compares a “precision” treatment plan with standard therapy for older adults with AML or MDS. It aims to improve outcomes while using treatments that may be better suited for people who cannot have intensive chemotherapy.
LørenskogAges 60 years+ - NCT05035147RecruitingPhase 4
Albumin-bound paclitaxel plus gemcitabine for advanced pancreatic cancer
This trial studies a chemotherapy combination (albumin-bound paclitaxel and gemcitabine) as first treatment for pancreatic cancer that cannot be removed by surgery. It aims to improve outcomes by testing how well this treatment works in people with locally advanced or metastatic disease.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05010863Recruiting
Test and develop a stomach cancer detection kit
This study looks for marker signals from stomach cancer tissue to improve a detection kit. You may be asked to provide tissue samples, especially if you have a new stomach cancer diagnosis and have not had anti-cancer treatment yet.
Wenzhou, ZhejiangAges Any age - NCT04455932Recruiting
Test shorter MRI versus ultrasound for liver cancer screening
This study compares a shorter, non-contrast MRI and ultrasound to monitor for liver cancer in people with cirrhosis whose ultrasound images aren’t clear enough. It aims to see which method works better and may help you get safer, more reliable follow-up.
Camperdown, New South WalesAges 20–85 - NCT05022914Recruiting
PSMA PET/CT scan for PSA relapse after prostate surgery
This trial looks at using a PSMA PET/CT scan to better re-check cancer activity in men whose PSA has started rising after prostate removal. If you qualify, the scan may help doctors choose the next best treatment step.
FlorenceAges 18 years+ - NCT02838602Recruiting
Carbon beam radiation vs standard radiation for resistant tumors
This study compares carbon beam radiation with standard radiation for tumors that are less likely to respond to usual radiation. It aims to see whether carbon beams can improve control of the cancer while keeping side effects manageable.
AmiensAges 18 years+ - NCT05033691Recruiting
Osimertinib plus early brain radiation versus osimertinib alone
This trial tests whether starting focused radiation to brain spots early (called SRS) along with osimertinib works better than taking osimertinib alone. It is for people with lung cancer that has an EGFR mutation and has not yet caused major brain symptoms.
