Bethesda, MarylandAges 18–72 - NCT03357120Recruiting
Using blood DNA to assess response after breast cancer chemotherapy
This study checks whether a blood test that looks for “tumor DNA” (circulating tumor DNA) can help evaluate how well neoadjuvant chemotherapy worked for breast cancer. It may help doctors better understand treatment response after surgery.
BordeauxAges 18 years+ - NCT03321045RecruitingEarly Phase 1
PET scan to predict benefit from HER2-targeted breast cancer therapy
This early-phase study uses a special PET scan with a drug tagged for imaging to predict how well HER2-targeted treatments will work. It may help doctors choose the most effective therapy for HER2-positive breast cancer.
Birmingham, AlabamaAges 18 years+ - NCT05323409Recruiting
Better overall care for certain cancer patients
This study looks at how to improve day-to-day support and coordination between cancer doctors and primary care doctors for people with certain early cancers. It may help if you have other ongoing health problems (like diabetes or high blood pressure) or lifestyle factors that need ongoing management during cancer treatment.
Houston, TexasAges 18 years+ - NCT06507618RecruitingPhase 3
Pre-surgery hormone therapy to guide radiation decisions for breast cancer
This trial tests whether taking hormone therapy for 3 months before breast-conserving surgery can help doctors decide if radiation is right for you. It is for women aged 65 and older with a common type of breast cancer that is hormone receptor-positive and HER2-negative.
New Haven, ConnecticutAges 65 years+ - NCT07676461Recruiting
Microbiome study in advanced cancer patients starting immunotherapy
This study looks at the bacteria in your mouth, gut, and tumors to see if they affect how well first-line immunotherapy works. It is for people with advanced stomach, colorectal, breast, cervical, or head-and-neck cancer.
Bogotá, Bogota D.C.Ages 18 years+ - NCT07675967Recruiting
Blood Cell Changes During Cancer Treatment
This study is for people with solid tumors who are about to start chemotherapy or radiation. It looks at how these treatments affect blood cells and may help doctors understand changes in blood health over time.
Boston, MassachusettsAges 18 years+ - NCT05361837Recruiting
Nerve block with sedation for breast surgery comfort
This trial tests if adding a numbing injection (serratus anterior plane block) with a calming medicine (dexmedetomidine) helps reduce pain during and after breast removal surgery.
Cairo, Cairo GovernorateAges 18–65 - NCT02743858Recruiting
Watch swelling study after breast lymph node surgery
This study looks at how and when swelling (lymphedema) happens after breast cancer surgery on the armpit lymph nodes. You may be followed closely after your planned one-sided procedure to better understand who gets swelling and how it changes over time.
Basking Ridge, New JerseyAges 18 years+ - NCT00068003Enrolling by invitation
Harvesting Cancer Cells for Experimental Treatment
This trial collects immune cells from cancer patients or healthy volunteers to develop new experimental cancer treatments. Researchers will take a sample of your tumor or blood cells, grow them in the lab, and study how to use them to fight your cancer.
Bethesda, MarylandAges 18 years+ - NCT01173341Enrolling by invitation
