Recruiting studies
- NCT06218303RecruitingPhase 1
Vaccine for early breast cancer (DCIS)
This trial tests a vaccine that targets a protein (MUC1) found in early breast cancer cells. It's for women with ER+ DCIS who are planning surgery, to see if the vaccine can help prevent the cancer from coming back or getting worse.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07762924RecruitingPhase 2
Skipping radiation for younger women with low-risk DCIS
This study is looking at whether it is safe for younger women who have had surgery for a very early-stage, low-risk breast condition called DCIS to skip radiation therapy. The goal is to see if they can avoid the side effects of radiation without the cancer coming back.
ShanghaiAges Up to 40 years - NCT07762885RecruitingPhase 3
Comparing skipping radiation after surgery for early-stage DCIS
This trial compares skipping radiation therapy after breast-conserving surgery for low- or intermediate-risk ductal carcinoma in situ (DCIS) – a very early, non-invasive breast cancer. It aims to see if omitting radiation is as effective as standard treatment while reducing side effects.
ShanghaiAges 40 years+ - NCT05327608RecruitingPhase 2
Time-restricted eating during breast cancer chemotherapy
This study is testing whether time-restricted eating (confining all meals to a specific window each day) can improve the response to chemotherapy in women with newly diagnosed breast cancer. Participants will follow this eating pattern for 16 weeks while receiving their standard chemotherapy, and the researchers will monitor how the tumor shrinks.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06075953RecruitingPhase 2
Testing Active Surveillance for Hormone-Positive DCIS After Surgery
This trial tests whether active surveillance (close monitoring) is a good option for certain patients with hormone-positive DCIS who have positive surgical margins after initial surgery. You would receive no immediate additional treatment—just regular imaging and check-ups.
Berkeley, CaliforniaAges 18 years+ - NCT06184750RecruitingPhase 2
Finding the best tamoxifen dose to lower breast cancer risk
This trial tests different doses of tamoxifen to find the best one for lowering breast cancer risk in premenopausal women. It aims to see if a lower dose works as well as the standard dose with fewer side effects.
Tucson, ArizonaAges 18–55 - NCT03909282Recruiting
Surgery now versus radiation then delayed surgery for DCIS
This trial compares two approaches for ductal carcinoma in situ (DCIS): having surgery first versus getting radiation first and then having surgery later. It aims to see which plan controls DCIS better while affecting treatment timing and outcomes.
Stanford, CaliforniaAges 18 years+ - NCT04144023RecruitingPhase 1
Vaccine before surgery for HER2-positive breast duct cancer in place
This Phase 1 study tests a vaccine (H2NVAC) given before surgery to help the body fight HER2-expressing ductal carcinoma in situ (DCIS) that has not been removed yet. Because it’s early-stage, the main goal is to check safety and learn how the treatment may work.
Jacksonville, FloridaAges 18 years+ - NCT04666961RecruitingPhase 2
Hormone therapy before surgery for extensive DCIS
This Phase 2 study tests whether taking hormone medicine before surgery can change the surgical plan and outcomes for people with extensive ductal carcinoma in situ (DCIS). It is for estrogen-receptor positive DCIS and aims to see how this “neoadjuvant” approach affects treatment decisions.
AngersAges 40 years+ - NCT04959474Recruiting
Pre-surgery radiation study with or without calorie restriction
This trial looks at whether a planned calorie-reduction diet before surgery can change how early breast cancer responds to a short course of radiation. It may help people understand if diet could improve outcomes alongside standard pre-surgery treatment.
Philadelphia, PennsylvaniaAges 40 years+ - NCT04985032Recruiting
Radiation after lumpectomy for selected breast tumors
This trial tests a shorter, focused type of radiation (APBI using SBRT) after lumpectomy for certain early breast cancers. It may help by targeting only the part of the breast where the tumor was, rather than treating the whole breast, while keeping safety and cancer control in mind.
Stuart, FloridaAges 50–100 - NCT05218044Recruiting
Cryoablation for small DCIS instead of breast surgery
This trial studies whether cryoablation (freezing abnormal breast tissue) can treat DCIS, a non-invasive early breast cancer, without surgical lumpectomy. It aims to see if a less invasive approach could help people with small, limited-area DCIS while avoiding some effects of surgery.
Glendale, CaliforniaAges 18 years+ - NCT06195306RecruitingPhase 2
Low dose tamoxifen and omega-3 for breast cancer prevention
This study tests whether low-dose tamoxifen (a breast cancer prevention drug) or omega-3 supplements can lower breast cancer risk in postmenopausal women who are overweight and have a higher chance of getting the disease. The study lasts about 6 months and involves blood draws and a breast fluid test to see how the treatment affects breast cells.
Kansas City, KansasAges 45–74 - NCT06350500Recruiting
Patient navigation for breast cancer care barriers
This study helps women with a new breast cancer or DCIS diagnosis who face barriers to care. A patient navigator will work with you to address issues like transportation, insurance, or other needs so you can get the care you need.
Buffalo, New YorkAges 18 years+ - NCT05941520RecruitingPhase 2
Acolbifene vs low-dose tamoxifen to prevent breast cancer
This Phase 2 trial compares acolbifene and low-dose tamoxifen to see which better lowers breast cancer risk in premenopausal women at high risk. You would be followed with health visits, blood tests, and a breast tissue sampling procedure.
Duarte, CaliforniaAges 35 years+ - NCT07331506Recruiting
Early detection of breast cancer with a blood test
This trial tests a new blood test called Oncoliq to see if it can find breast cancer early. It compares results from people with breast cancer and people without cancer.
Buenos Aires, Buenos AiresAges 40–70 - NCT06843681Enrolling by invitationPhase 2
Trastuzumab and Chemo Before Surgery for HER2-Positive DCIS
This trial tests giving trastuzumab (a targeted drug) plus a chemotherapy drug called a taxane before surgery for women with HER2-positive ductal carcinoma in situ (DCIS), an early form of breast cancer. The goal is to see if this combination can shrink or eliminate the cancer before surgery.
Guangzhou, GuangdongAges 18–70 - NCT06961955RecruitingPhase 2
Shorter versus longer whole breast radiation for early-stage breast cancer
This trial compares a 5-day course of whole breast radiation plus a boost to the standard 9-day course for people with early-stage breast cancer who have certain risk factors, such as high-grade tumors or younger age. The goal is to see if the shorter treatment is just as safe and effective.
Salt Lake City, UtahAges 18 years+ - NCT02918474Recruiting
Decision tool for mastectomy choices in new breast cancer
This study tests a decision-making tool to help people with newly diagnosed breast cancer make choices about removing the other (opposite) breast as a preventive step. It may help you think through risks and options in a clearer, more structured way.
Houston, TexasAges 18 years+ - NCT04169542Recruiting
Study on how COVID-19 affected costs for breast surgery patients
This study asks people with breast cancer who are having breast surgery about how COVID-19 affected their out-of-pocket costs, work income, and job stability. Your answers may help improve support for patients during public health emergencies.
Conroe, TexasAges 18 years+ - NCT04084730RecruitingPhase 2
3-day radiation after breast-conserving surgery for certain breast cancers
This trial tests whether a shorter, 3-day course of partial breast radiation after surgery works as well as standard radiation for women with early-stage breast cancer. It may help reduce time in treatment while aiming to keep cancer from coming back in the treated breast area.
Norwalk, ConnecticutAges 45 years+ - NCT07339306Recruiting
Fluorescent needle test for breast duct micro-lesions
This trial tests a new glowing needle that helps doctors find and sample tiny abnormal areas in breast ducts during surgery. It aims to make the procedure more precise.
Shenyang, LiaoningAges 18–75 - NCT07711847Recruiting
Prone positioning for faster breast radiation therapy
This trial tests a personalized prone-immobilization device for partial breast radiation after surgery. It aims to make treatment more comfortable and accurate for patients who have had breast-conserving surgery.
New York, New YorkAges 40 years+ - NCT04797299Recruiting
Testing surgery alone for low-risk ductal carcinoma in situ
This trial studies whether removing the abnormal breast cells with breast-conserving surgery only (without additional treatment) is enough for people with low-risk ductal carcinoma in situ (DCIS). It may help some patients avoid extra treatments if their risk is very low.
