Atlanta, GeorgiaAges 18 years+ - NCT04799002RecruitingPhase 3
Topotecan and melphalan for eye-sparing retinoblastoma treatment
This trial studies whether a combination chemotherapy treatment (topotecan plus melphalan) can help children with retinoblastoma while keeping the eye when possible. It’s a Phase 3 study, meaning it’s testing effectiveness in a larger group of patients.
Guangzhou, GuangdongAges Any age - NCT04750122RecruitingPhase 1/Phase 2
Drug-screening guided treatment before surgery for HER2 breast cancer
This trial tests a treatment plan that is chosen using drug-testing in a lab (to see which medicines may work best) before surgery. It is for people with early-stage HER2-positive breast cancer, aiming to improve outcomes by guiding the right treatment early.
Beijing, Beijing MunicipalityAges 18–75 - NCT04824950Recruiting
Blood DNA test in newly diagnosed mediastinal large B-cell lymphoma
This study looks at how “circulating tumor DNA” in blood changes in people with newly diagnosed primary mediastinal large B-cell lymphoma. It may help doctors better monitor treatment response alongside standard PET/CT-guided care, which could improve follow-up decisions.
LyonAges 18 years+ - NCT03541928RecruitingPhase 2
Gene therapy with standard treatment for high-risk prostate cancer
This trial combines gene therapy with hormone therapy, radiation, and possibly surgery to treat high-risk prostate cancer. It aims to improve outcomes by adding gene therapy to standard treatments and will require additional biopsies.
Houston, TexasAges 18 years+ - NCT04126876RecruitingPhase 2
IMO-2125 skin injection for thick, early-stage melanoma
This trial tests whether an injection given into the skin (IMO-2125) can improve outcomes for people with thicker primary melanoma that has not spread to lymph nodes or other organs. Participants also have planned surgery to remove the tumor and check a sentinel lymph node.
AmsterdamAges 18 years+ - NCT04019678Recruiting
Breast cancer study after chemotherapy with small underarm node spread
This study looks at whether it’s safe and effective to avoid removing many underarm lymph nodes in some people who, after chemotherapy, still seem to have only tiny (“micro”) cancer deposits in the sentinel lymph node. It may help reduce treatment side effects while keeping cancer control.
Rozzano, MIAges 18–75 - NCT04829708RecruitingPhase 3
Preventing brain spread in limited-stage small cell lung cancer
This trial compares two ways to manage limited-stage small cell lung cancer that has improved after initial chemotherapy and radiation. Participants will either get preventive brain radiation or have regular brain MRI scans instead, to see which approach is safer and works better.
Jinan, ShandongAges 18–75 - NCT03961776Recruiting
MRI to monitor treatment response in rectal cancer
This trial tests whether an MRI scan done during chemoradiation can help doctors track how rectal cancer treatment is working. It may improve how they measure response early so treatment planning can be better tailored.
Los Angeles, CaliforniaAges 18 years+ - NCT04834544RecruitingPhase 2
Maintenance vaccine treatment after first chemotherapy for ovarian cancer
This Phase 2 trial studies a maintenance vaccine (DCVAC/OvCa) given after standard first-line chemotherapy and surgery for certain advanced ovarian cancers. It aims to help keep the cancer from coming back for longer by boosting the body’s anti-cancer response.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04878666Recruiting
Breast cancer chest-wall recurrence quality of life with heat treatment
This trial studies how a special heating radiation treatment (“hyperthermia radiotherapy”) affects quality of life in people whose breast cancer has come back in the chest area. It may help show whether this treatment approach is tolerable and beneficial for everyday well-being.
Tübingen, Baden-WurttembergAges 18 years+ - NCT04843215Recruiting
Surgery comparison for advanced stomach cancer after initial surgery
This trial studies whether removing all of the fatty lining (omentum) or only part of it during surgery leads to better outcomes in people with advanced stomach cancer. It also checks that participants can safely have the same stomach-cancer chemotherapy plan after surgery.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT04576143RecruitingPhase 2/Phase 3
Dose-dense chemo before surgery for HER2-negative breast cancer
This trial studies a faster, higher-frequency chemotherapy schedule given before surgery for HER2-negative breast cancer. It aims to see if this approach works better and is safe for the patient’s cancer stage.
Hangzhou, ZhejiangAges 18–70 - NCT03791034Recruiting
Blood DNA test to guide treatment in early lung cancer
This trial studies a “cell-free DNA” blood test to help diagnose and guide treatment decisions for early non-small cell lung cancer. It may help doctors tailor care based on genetic signals seen in the blood before and around surgery.
SeoulAges 18–90 - NCT04905056RecruitingPhase 2
Ablation treatment for lung ground-glass nodules that don’t go away
This Phase 2 trial studies whether a procedure called “ablation” is safe and effective for certain lung cancers that appear as ground-glass spots on CT scans and do not improve after 3 months. It may help people who cannot fully have surgery for their condition.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT03353467Recruiting
Surgery through the nose for early nasopharyngeal cancer
This trial tests whether a minimally invasive surgery done through the nose can help people newly diagnosed with early-stage nasopharyngeal cancer. It looks for patients who have not had prior cancer treatment and who are healthy enough for the procedure and follow-up.
Guangzhou, GuangdongAges 18–70 - NCT04908566RecruitingPhase 2
PD-1 immunotherapy plus chemotherapy before and after gastric surgery
This trial studies whether adding a PD-1 immune therapy to chemotherapy around the time of surgery can improve outcomes for people with locally advanced stomach or stomach–esophagus junction cancer. It aims to better control the cancer before and reduce the chance it comes back after surgery.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT04900558Recruiting
Study outcomes after robotic bladder removal surgery
This trial follows adults who are planning to have a robotic radical cystectomy (surgery to remove the bladder and surrounding tissue) to learn what outcomes to expect. If you choose to join and meet the basics, it may help your team compare results and improve care for future patients.
Florence, TuscanyAges 18 years+ - NCT04331093RecruitingPhase 2
Pre-surgery treatment for stage III–IV melanoma with two medicines
This trial tests two medicines given before surgery to shrink stage III–IV acral melanoma (a melanoma type on the hands/feet) and improve outcomes. If the tumors respond, surgery can happen afterward as planned.
Changchun, JilinAges 18–75 - NCT05032768Recruiting
Study links between skin bacteria and radiation skin reactions
This study looks at how changes in the skin’s normal bacteria (microbiome) relate to getting redness, irritation, or rash after breast radiation. It may help doctors predict who is more likely to have skin side effects after reconstruction and radiation.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT03869619Recruiting
Real-life data study for adults with recent lymphoma
This study collects “real-world” health information about adults whose lymphoma was diagnosed within the last 6 months. It aims to better understand lymphoma types and how patients do over time, using data from everyday care rather than testing a new drug.
ArrasAges 18 years+ - NCT04960839Recruiting
Preventive radiation to the other breast after breast cancer surgery
This study looks at whether “preventive” radiation to your other (opposite) breast can lower the chance of future breast cancer in people at higher genetic risk. You must have had surgery for early-stage breast cancer and agree to avoid removing the other breast and ovaries.
Jiangxi, JiangxiAges 30–70 - NCT04947280RecruitingPhase 1/Phase 2
Radiation split into small doses for breast cancer bone spread
This trial studies a type of focused radiation given in smaller parts to treat bone metastases from breast cancer. It may help shrink tumors and improve control of pain or growth when standard treatments haven’t worked or surgery isn’t possible.
Shanghai, Shanghai MunicipalityAges Any age - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
