Recruiting studies
- NCT00437879Recruiting
Ultrasound and MRI scans to track breast cancer response early
This study uses ultrasound and/or MRI scans to see how breast cancer responds early while you start “neoadjuvant” treatment (chemotherapy, with or without radiation before surgery). It may help doctors spot response sooner and better understand which imaging changes match treatment benefit.
Toronto, OntarioAges Any age - NCT01000883Recruiting
Biopsy study linking breast cancer tissue markers to treatment response
This study looks at breast cancer samples taken by biopsy to see how tissue “molecular markers” relate to how you respond to therapy and how the cancer behaves. It may help researchers better match future treatments to the biology of your tumor.
Chapel Hill, North CarolinaAges 18 years+ - NCT01521741Recruiting
Breast cancer lymphedema screening to detect early swelling
This trial looks at whether scheduled measurements can spot early swelling (lymphedema) in people with breast cancer. It may help find problems sooner so treatment or prevention steps can start earlier.
Boston, MassachusettsAges 18 years+ - NCT00898131Recruiting
Donate tissue samples during breast cancer surgery for future research
This study collects small tissue samples from women having surgery for breast cancer. The samples are stored to help researchers learn more and develop better treatments in the future.
Chicago, IllinoisAges Any age - NCT01042548Recruiting
Testing blood and tissue markers in breast surgery patients
This study looks at proteins and imaging patterns (from tissue, fluid near the tumor, and blood) to better understand breast cancer markers. It may help researchers find clues that doctors can use to evaluate breast nodules and newly diagnosed invasive breast cancer.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT01284153Recruiting
Testing breast cancer radiation plans in a prone position
This study compares how well radiation treatment plans can be made when you lie face-down (prone) for breast cancer. It’s a planning study, meaning the main goal is to improve treatment planning and potential safety/comfort.
LeuvenAges Any age - NCT01530373RecruitingPhase 2
Solifenacin vs clonidine to reduce breast cancer hot flashes
This trial compares two medicines—solifenacin and clonidine—to see which one better reduces hot flashes in people taking hormone-blocking cancer medicines. If you have frequent hot flashes, joining could help researchers find an effective option for symptom relief.
Little Rock, ArkansasAges 18 years+ - NCT02290834Recruiting
Studying brain and thinking changes after chemotherapy in older breast cancer patients
This study looks at how chemotherapy may affect memory and thinking, using thinking tests and possibly brain imaging. It compares older breast cancer patients who do and do not get chemotherapy, plus a group of healthy older adults.
Boston, MassachusettsAges 60 years+ - NCT02250352Recruiting
Biopsy study to collect breast tumor tissue samples
This study takes small tissue samples (core biopsies) from people with known or suspected breast cancer and stores them for research. It may help scientists better understand breast tumors, especially when the cancer has spread.
Los Angeles, CaliforniaAges 18 years+ - NCT02897700RecruitingPhase 1
Testing chemotherapy choices for early breast cancer after surgery
This Phase 1 study tests different chemotherapy approaches in people with breast cancer that has been surgically removed but is early stage. It aims to find a chemotherapy plan that’s safe and works well right after surgery.
Ganzhou, JiangxiAges 18 years+ - NCT02732860Recruiting
Test your tumor’s drug response using a lab model
This trial grows a lab model from your own tumor tissue (or resected tissue) to predict which drugs might work best. It’s meant to match investigational treatments to your specific tumor biology.
Toronto, OntarioAges 18 years+ - NCT02772367Recruiting
Make heart muscle cells from blood or skin in breast cancer
This study grows heart muscle cells from your blood or skin to better understand why some people develop heart problems from HER2 cancer treatments. You may be helping researchers learn how to predict and prevent treatment-related heart damage.
New York, New YorkAges 18 years+ - NCT02839863Recruiting
Breast cancer care follow-up at UMC Utrecht with surveys
This study follows people with breast cancer who receive radiation at UMC Utrecht. It uses routinely collected medical data and questionnaires to better understand outcomes over the long term.
AlmeloAges 18 years+ - NCT02732171Recruiting
Blood and bone marrow tests to track breast cancer return
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02610426Recruiting
Genetic testing to study who develops heart failure during breast cancer therapy
This study uses DNA genetic testing to find DNA changes that might explain why some people develop heart failure (CHF) after breast cancer treatment with certain medicines. It may help researchers understand risk and improve care for future patients.
Boston, MassachusettsAges Any age - NCT02389673Recruiting
Radiation during breast surgery for low-grade DCIS
This trial studies giving radiation during surgery for women with a certain early breast condition called ductal carcinoma in situ (DCIS). It may help lower the chance that the DCIS comes back, especially when combined with breast-conserving surgery.
Guangzhou, GuangdongAges 18–70 - NCT02422641RecruitingPhase 2
High-dose methotrexate for breast cancer in the brain lining
This Phase 2 trial tests whether giving high-dose methotrexate into the bloodstream can help treat breast cancer that has spread to the thin lining covering the brain and spinal cord. It may help reduce cancer in the leptomeningeal (brain-lining) area and control symptoms.
Baltimore, MarylandAges 18 years+ - NCT02893761Recruiting
Bergonié Institute breast cancer database study
This study collects information from people who are receiving their first breast cancer treatment at the Bergonié Institute. It helps the institute better understand breast cancer care and outcomes over time.
BordeauxAges 18 years+ - NCT02535221RecruitingPhase 3
Hormone treatment vs chemotherapy before breast surgery
This Phase 3 trial compares hormone-based treatment versus chemotherapy given before surgery in people who are premenopausal and have hormone-receptor positive, HER2-negative breast cancer. It looks to see which approach works better to control the cancer before the breast operation.
BeijingAges 35–55 - NCT02541435Recruiting
Breast cancer radiotherapy side effects study
This study looks at heart and blood-vessel side effects after modern radiation treatment for breast cancer, both soon after and years later. It may help doctors understand who is at risk and how to monitor heart health over time.
ÅlesundAges 30–70 - NCT02610413Recruiting
DNA testing to explain who gets severe blood pressure with bevacizumab
This study uses whole exome DNA testing to look for inherited genetic differences that may explain why some people develop very high blood pressure from bevacizumab during breast cancer treatment. It compares people who did vs. did not develop severe bevacizumab-related hypertension.
Boston, MassachusettsAges Any age - NCT02610439Recruiting
Genetic testing to find causes of paclitaxel nerve damage
This study uses genetic tests on blood DNA to look for differences that may explain why some people develop nerve pain (peripheral neuropathy) from paclitaxel used for breast cancer. It compares people who got significant neuropathy during treatment with people who did not get neuropathy after completing paclitaxel.
Boston, MassachusettsAges Any age - NCT02869607Recruiting
