This trial tests whether two medications, ketorolac (a pain reliever) and pregabalin (a nerve pain drug), can help treat estrogen receptor (ER) positive breast cancer when taken before surgery. It may offer better pain control and possibly improve cancer outcomes.
Brussels, Brussels CapitalAges 18–70 - NCT06150417RecruitingPhase 2
Study of extra radiation for prostate cancer spread to few spots
This study tests whether adding a type of high-precision radiation (MDRT) to standard hormone therapy works better for men with prostate cancer that has spread to just a few places. It is for patients who are newly diagnosed and on long-term hormone therapy.
New York, New YorkAges 18 years+ - NCT06141993Recruiting
Study of blood markers in hormone therapy resistance for prostate cancer
This study is for men with advanced prostate cancer that stopped responding to one hormone therapy and will be starting another. Researchers will collect blood samples to look for markers that might explain why the resistance happens.
New York, New YorkAges 18 years+ - NCT06135714RecruitingPhase 3
Targeting limited breast cancer spread with focused therapy
This trial tests whether treating just the few spots where breast cancer has spread (called oligometastases) with radiation or surgery can help control the disease. It is for people whose cancer has spread to 3 or fewer places, each small in size, and who are healthy enough for local treatments.
Bunkyō-Ku, TokyoAges 18 years+ - NCT00823654Recruiting
Blood tests during treatment to track ovarian egg supply
This study measures blood biomarkers to understand how breast cancer treatment affects a person’s future fertility (ovarian reserve). It may help patients learn more about egg supply changes after chemotherapy and hormone-related treatments.
Basking Ridge, New JerseyAges 18–44 - NCT05784922Recruiting
Lung cancer screening support for eligible smokers
This study aims to improve and promote lung cancer screening for people at higher risk who may face barriers. You may be asked to share your experiences through surveys or focus-group style activities to help make screening more equitable.
Boston, MassachusettsAges 50–80 - NCT06117059Recruiting
Precision study: 3 session prostate radiation with special guidance
This trial tests a new way to give prostate radiation using just 3 sessions with a special guidance system (RayPilot HypoCath) to target the tumor more accurately and safely.
EdinburghAges Any age - NCT03160274Recruiting
Genetic testing for certain adrenal and nerve tumors
This study looks at genetic (DNA) changes in people with pheochromocytoma or paraganglioma and related conditions. It may help clarify why these conditions happen and how they run in families.
San Antonio, TexasAges Any age - NCT06127979Recruiting
Hormone therapy before surgery for breast cancer
This study looks at how a hormone-blocking medicine (endocrine therapy) given before surgery affects a marker called Ki67 in your breast cancer cells. The goal is to see if the medicine can slow the growth of the cancer, which may help doctors choose the best treatment for you.
New York, New YorkAges 18 years+ - NCT06108089Recruiting
Hypoxia imaging for head and neck cancer treatment planning
This study uses a special MRI scan to measure oxygen levels in your head and neck tumor. The goal is to learn if this scan can help doctors choose the best treatment plan for you.
Salt Lake City, UtahAges 18 years+ - NCT06116032Recruiting
Immune profiling for cancer immunotherapy response
This trial studies immune system changes in cancer patients receiving immunotherapy, such as checkpoint inhibitors or cell therapies. It aims to understand why some people respond better than others.
Lebanon, New HampshireAges 18 years+ - NCT06115486Recruiting
Exercise to improve muscle after breast cancer treatment
This trial tests whether a structured exercise program (called EXERT-BCH) can help improve muscle mass in women who have finished breast cancer treatment. It involves group resistance training sessions and is designed to support recovery and strength.
Pittsburgh, PennsylvaniaAges 20–89 - NCT06111105Recruiting
Comparing blood tests to guide colon cancer treatment
This study compares different blood tests to find the best way to detect tiny bits of cancer DNA after surgery for stage III colorectal cancer. It aims to help doctors decide if additional chemotherapy is needed to prevent the cancer from coming back.
Graz, StyriaAges 18 years+ - NCT06114108Recruiting
Adding local treatment to drug therapy for stage IV lung cancer
This trial compares continuing drug therapy alone versus adding local treatments (surgery or radiation) for people with stage IV lung cancer that has responded to initial treatment but still has a few remaining spots (oligometastatic). The goal is to see if targeting those spots with local therapy helps control the cancer longer.
AarauAges 18 years+ - NCT06123988Recruiting
Fasting and exercise for advanced breast cancer
This study looks at whether fasting overnight and/or doing exercise can help improve fatigue and other quality-of-life measures in women with advanced hormone receptor positive breast cancer who are already taking a CDK4/6 inhibitor. Participation may involve following a fasting or exercise plan for a period of time.
Phoenix, ArizonaAges 18 years+ - NCT06105749Recruiting
Biennial contrast-enhanced mammogram for breast cancer survivors
This study tests whether getting a contrast-enhanced mammogram (CEM) every two years is effective for detecting breast cancer in women who have had breast cancer before. If you qualify, you will receive CEM instead of a standard mammogram to see if it helps find cancer earlier.
Bethel Park, PennsylvaniaAges 30–79 - NCT06127797Recruiting
MRI surveillance study for breast cancer survivors with dense breasts
This study is testing whether adding an MRI to your regular mammogram can help find any new breast cancers earlier. It is for women who have had breast cancer before and still have dense breast tissue, making mammograms harder to read.
Houston, TexasAges 18 years+ - NCT06123338RecruitingPhase 2
Pembrolizumab plus chemo and trastuzumab for HER2+ stomach cancer
This trial tests adding pembrolizumab to standard trastuzumab and chemotherapy for people with HER2-positive stomach or esophageal cancer that can be fully removed with surgery. The goal is to see if this combination improves outcomes before and after surgery.
Boston, MassachusettsAges 18 years+ - NCT05620329Recruiting
Pleural fluid registry for drainage in adults
This registry collects information from adults who have fluid around the lungs (pleural effusion) and need clinically indicated drainage because of infection or cancer. It helps researchers better understand these conditions and improve future care.
Chapel Hill, North CarolinaAges 18 years+ - NCT06052488Recruiting
Strength After Breast Cancer
This study tests a strength training program for women who have finished primary treatment for early-stage breast cancer. The goal is to see if it helps improve muscle strength and overall recovery.
