DUCTAL CARCINOMA IN SITU

This trial tests a new device called the EndoSCell Scanner, which uses fluorescence imaging to help surgeons see if any cancer cells remain after removing a breast tumor. About 172 women with breast cancer will have their surgical cavity scanned during surgery. If the scanner det…

This study is for women whose breast cancer has come back after initial breast-conserving surgery and whole breast radiation. The standard treatment after repeat surgery is radiation twice a day for 30 sessions. This trial tests whether giving radiation once a day for 15 sessions…

This study tests a new dye called Magtrace that stays in the lymph nodes for weeks. For women with non-invasive breast cancer (DCIS) having a mastectomy, this dye may allow doctors to safely delay lymph node removal until after the breast tissue is checked for hidden invasive can…

This study tests whether active surveillance (close monitoring) combined with hormonal therapy can safely manage ductal carcinoma in situ (DCIS), a very early form of breast cancer. About 400 women with hormone-positive DCIS will receive either standard or investigational hormone…

This study compares two surgical approaches for breast cancer: one that removes extra tissue around the tumor (routine cavity shave margins) and one that uses a special device (Savi Scout®) to guide removal of only suspicious margins. About 204 women with early-stage breast cance…

This study tests a new, ultra-short radiation schedule for early-stage breast cancer. Instead of the usual 3 weeks, patients receive 5 radiation sessions over one week, with an extra boost to the tumor site given at the same time. The goal is to see if this approach is safe, redu…

This study looks at how different group exercise programs affect fitness and body composition in women who have finished breast cancer treatment. About 15 women will try one of four supervised resistance training regimens. The goal is to see which approach best improves heart-lun…

This study is for women aged 51 or older whose breast cancer has returned or who have a new cancer in the same breast. The goal is to see if giving a focused, short course of radiation before surgery is safe and effective enough to allow breast-conserving treatment instead of mas…

This study tests a special scanner that helps surgeons see if any cancer cells are left behind during breast-conserving surgery. The goal is to remove all cancer in one go and avoid a second operation. About 100 women with invasive or in-situ breast cancer will take part. The sca…

This registry study is following 500 women with early-stage breast cancer who receive a single dose of radiation directly to the tumor site during surgery (IORT). The goal is to see how well this approach controls cancer locally and what side effects occur. Participants are women…

This study tests proton radiation therapy for women with early-stage breast cancer. The goal is to see if targeting only the tumor area can keep cancer from coming back while causing fewer side effects. About 132 women aged 50 and older will take part. Researchers will track recu…

This study tests a new imaging method called FAPI-PET/MRI to see if it can detect hidden invasive breast cancer in 30 people diagnosed with ductal carcinoma in situ (DCIS), a common pre-stage of breast cancer. Participants receive a weakly radioactive drug and lie in a scanner fo…

This study tests a new handheld device that uses light and artificial intelligence to check for leftover cancer cells right after a breast lump is removed. The goal is to help surgeons remove all cancer in one go, avoiding a second surgery. About 104 women having breast-conservin…

This early-stage trial is testing whether a vaccine targeting the MUC1 protein, combined with hormone therapy, can help prevent ductal carcinoma in situ (DCIS) from becoming invasive breast cancer. Fifty women with ER-positive DCIS will receive either hormone therapy alone or hor…

This study looks at whether a structured 12-week exercise program can improve fitness and recovery in women who have had DIEP flap breast reconstruction after mastectomy. Half of the 78 participants will follow the exercise program, while the other half will receive standard care…

This study is testing a very short course of radiation therapy for women with early-stage breast cancer. Instead of weeks of treatment, participants receive whole breast radiation with a targeted boost over just 5 days. Researchers will track how the breast looks and feels, and h…

This study compares two ways to perform nipple-sparing mastectomy with immediate DIEP flap breast reconstruction: robotic-assisted surgery through a single small incision, versus the standard open surgery with a larger cut. The goal is to see which approach leads to better patien…

This study compares two standard exercise programs to see which one better helps women increase muscle mass after breast cancer treatment. Thirty women aged 20-89 who have completed treatment (except chemotherapy) will follow either standard resistance training or a special 6-12-…

This study tests a special ink called Magic Ink that is only visible under UV light, used to mark the skin for daily radiation treatment in breast cancer patients. The goal is to see if it is as safe and effective as standard permanent tattoo ink, while being less noticeable. Thi…

This study tests whether a decision aid tool called RECONJOINT is practical for helping women choose breast reconstruction after mastectomy. About 131 women with breast cancer or a genetic risk will use the tool. The goal is to see if a larger study can be done to improve shared …

This study aims to understand the current state of breast cancer care by surveying both patients and doctors. The goal is to identify gaps in communication and time management, and to develop new, patient-focused care models. About 2000 adults with breast cancer and their physici…

This study tests whether a new 3D imaging method used during breast cancer surgery helps surgeons remove all cancer cells the first time. About 314 women having breast-conserving surgery will be randomly assigned to either standard 2D imaging or the new 3D imaging. The goal is to…

This study is looking at how hormone treatments for breast cancer, called aromatase inhibitors and tamoxifen, affect blood sugar control and diabetes risk in postmenopausal women. Researchers will compare blood sugar measures in women taking these drugs to healthy women not on tr…

This study reviews data from 250 women who had a special type of breast-conserving surgery for early-stage breast cancer. The surgery uses nearby skin and fat flaps to fill the area where the tumor was removed, aiming to avoid visible scars and keep the breast looking natural. Re…

This pilot study looks at how social determinants of health—like housing, food, and transportation—relate to inflammation in women newly diagnosed with breast cancer. Participants fill out surveys and give a blood sample at a single visit. The goal is to understand these connecti…

This study tests a decision aid called BREASTChoice in 20 breast cancer patients who had breast surgery. Participants use the tool on their phones and share their thoughts in interviews. Researchers measure how much patients learn about reconstruction options using a knowledge su…

This study tests a new way to mark the area where a breast tumor was removed, so radiation therapy can be more accurately aimed afterward. About 50 adults with early-stage breast cancer or a precancerous condition called DCIS will take part. The goal is to see if this marking hel…
