Salt Lake City, UtahAges 18 years+ - NCT04845828Recruiting
Sentinel node biopsy versus full node removal in early uterine cancer
This study compares two ways to check lymph nodes during surgery for early-stage endometrial (uterine) cancer: sentinel node biopsy versus removing more lymph nodes. It may help find whether the less extensive approach can stage the cancer accurately with fewer side effects.
SeoulAges 20–80 - NCT04845893Recruiting
Study of Ewing and related bone cancers
This is an observational study that follows people with Ewing’s sarcoma of the bone and certain “Ewing-like” tumors. It helps doctors understand the extent of disease at diagnosis and track outcomes, which may guide better planning for future care.
Rozzano, MIAges birth–49 years - NCT04846309RecruitingPhase 1
MRI scan to personalize radiation for esophageal cancer
This Phase 1 study uses specialized imaging (including MRI) to better “see” low-oxygen areas in esophageal cancer and help guide individualized radiation treatment. It aims to improve how radiation is planned and delivered while checking safety.
Salt Lake City, UtahAges 18 years+ - NCT04846933Recruiting
Testing extra scans and data to guide ovarian cancer treatment
This trial collects information from people with suspected ovarian cancer and uses it to improve diagnosis and help predict which treatments may work. It may also look for targeted options, based on scan and medical data results.
TurkuAges 18 years+ - NCT04847284Recruiting
Radiation during brain tumor surgery for brain metastases
This trial tests giving targeted radiation while surgeons are operating to treat brain metastases. It may help control the cancer locally at the time of surgery, especially for certain single lesions.
BarcelonaAges 18 years+ - NCT04847505RecruitingPhase 3
Testing 68Ga-DOTA-TATE PET/CT scans for neuroendocrine tumors
This trial looks at how useful a specific scan (68Ga-DOTA-TATE PET/CT) is for tumors that have certain “targets” (somatostatin receptors). It may help doctors better identify and guide care for neuroendocrine tumors.
Montreal, QuebecAges Any age - NCT04847063RecruitingPhase 1
Test drug heating inside the abdomen for peritoneal cancer
This Phase 1 trial tests a treatment that delivers heated chemotherapy directly into the abdomen (HIPEC) for certain cancers that have spread only within the abdominal lining. It aims to see how safely and effectively this approach works, especially when doctors can remove as much tumor as possible.
Bethesda, MarylandAges 18–120 - NCT04848064RecruitingPhase 1
Natural killer cells plus mogamulizumab for skin lymphoma
This early-phase study tests a combination of “natural killer” immune cells and a medicine called mogamulizumab to treat certain skin lymphomas that have come back or did not respond. It may help your immune system better find and attack cancer cells.
Columbus, OhioAges 18 years+ - NCT04849481Recruiting
Precision medicine planning for advanced lung cancer tissue testing
This trial uses your tumor sample to guide personalized treatment decisions for certain lung cancers. It may help by matching you to a more targeted plan based on genetic testing and your prior treatment history.
Chiayi CityAges 20 years+ - NCT04851119RecruitingPhase 1/Phase 2
Tegavivint for kids and young adults with hard-to-treat solid tumors
This early-phase study tests tegavivint to see how well it works and how safe it is for children and young adults with solid cancers that have come back or are not responding. It may be an option if your tumor type (including certain lymphomas or desmoid tumors) matches the study’s rules.
Birmingham, AlabamaAges 1–30 - NCT04850729Recruiting
Study links surgery medicines to the stomach tumor environment
This trial looks at how medicines given around the time of stomach cancer surgery may change the “tumor microenvironment,” which is the biology around the tumor. It may help doctors better understand which perioperative treatments work best for locally advanced, operable stomach cancer.
