This study tests whether people with symptomatic myeloma can safely learn to give themselves chemotherapy at home. It aims to make treatment easier while tracking safety and whether treatment is done correctly.
Calgary, AlbertaAges 18 years+ - NCT04271527Recruiting
Compare two prostate biopsy guidance methods in men with PSA rise
This trial tests whether using a “cognitive” approach versus a software-guided approach to plan a prostate biopsy is just as effective. It may help improve how biopsies are targeted for men with PSA changes and/or abnormal prostate exams.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04281381Recruiting
Watching desmoid tumors to understand what changes over time
This study follows people with desmoid-type fibromatosis using scans and health information to see how the tumor behaves. It may help patients and doctors decide when “watch and wait” is the right approach and when treatment is needed.
New York, New YorkAges 18 years+ - NCT04284969Recruiting
Study of surgery plan for advanced ovarian or peritoneal cancer
This trial looks at whether a specific treatment pathway that may include surgery helps people with advanced ovarian (or related) cancer. It mainly involves planning and undergoing a complex pelvic surgery, sometimes after chemotherapy, to improve outcomes.
BordeauxAges 70 years+ - NCT04286841Recruiting
Immunotherapy before lung surgery for early lung cancer
This trial looks at giving immunotherapy before surgery for certain early-stage lung cancers to help shrink the tumor and improve outcomes. It is mainly for people whose lung cancer can be removed by surgery and who don’t have specific gene changes like EGFR or ALK.
Guangzhou, GuangdongAges 18 years+ - NCT04290663RecruitingPhase 3
Radioiodine decision after thyroid surgery for intermediate-risk cancer
This study compares two approaches after thyroid surgery: giving radioactive iodine right away versus deciding based on follow-up test results. It aims to see which approach better helps people with intermediate-risk differentiated thyroid cancer.
Pointe à Pitre, GuadeloupeAges 18 years+ - NCT04290806Recruiting
SAPHIR registry for advanced stomach and esophagus cancer
This registry collects information from people with stage IV (metastatic) stomach or esophagus cancers who are about to start their first medicines to control the disease. It may help researchers understand which treatments are used and how patients do over time.
Multiple LocationsAges 18 years+ - NCT04291755Recruiting
Stool bank for people receiving cancer immunotherapy
This study is building a “stool bank,” meaning they collect and store stool samples from people who are getting cancer immunotherapy. Researchers plan to analyze these samples to better understand cancer and treatment—your participation may help future research.
Fountain Valley, CaliforniaAges 18 years+ - NCT04291651Recruiting
Pancreatic Cyst Registry for Adults With Pancreatic Cysts
This registry study collects information from adults who have a pancreatic cyst (a fluid-filled sac in the pancreas). It may help doctors understand these cysts and how they change over time, which can improve future care.
San Francisco, CaliforniaAges 18 years+ - NCT04294927Recruiting
Tube removal first, then ovaries later for high-risk women
This study looks at whether removing the fallopian tubes first, and the ovaries later, is safe for women with certain inherited gene mutations that raise ovarian cancer risk. It may help you understand a prevention approach when you’re considered high risk and have finished having children.
Chicago, IllinoisAges 25–50 - NCT04300998Recruiting
CAR-T therapy study for older adults
This study looks at how well CAR-T cell therapy works and how safely it can be given to older adults. It is for people whose cancer or related blood condition has come back or did not respond, and who are receiving a standard (commercial) CAR-T product.
