Summary: Participants will complete questionnaires before surgery, between 2 to 4 weeks after surgery, and 6 months after surgery.

Summary: This clinical research study is to learn about the effects of giving radiotherapy alone after lumpectomy to patients who have early-stage, low-risk breast cancers and who are 60 years of age or older.

Summary: The aim is to conduct a randomized controlled trial (RCT) with a high dose arm (1mg/kg) vs a low dose (8mg in total) of steroid (Dexamethasone) given intravenous (IV) after the induction of anesthesia to High-pain-responders in patients undergoing VATS lobectomy/segmentectomy. The hypothesis is that a high dose of Dexamethasone can lower pain when coughing in the morning after VATS lobectomy/segme...

Summary: Breast-conserving surgery followed by re-irradiation with partial breast irradiation (rPBI) has recently been found to be a safe alternative to mastectomy for women who have undergone prior whole breast radiation. By reducing the volume of tissue receiving radiation, rPBI has been associated with less toxicity and improved cosmetic outcomes. For many women with early-stage breast cancer, shorter 1...

Summary: This phase IIA trial compares the effect of acolbifene versus low dose tamoxifen in preventing breast cancer in premenopausal women at high risk for developing breast cancer. The usual approach for patients at increased risk for breast cancer is to undergo yearly breast magnetic resonance imaging or ultrasound in addition to yearly mammogram. Premenopausal women at very high lifetime risk for brea...

Summary: Breast reconstruction is a critical component of breast cancer treatment because it restores quality of life and body image after mastectomy. However, Spanish-speaking Latina women are significantly less likely to undergo reconstruction (13.5% vs. 41% for non-Latina White or highly acculturated Latina), meet with a reconstructive surgeon (18.1% vs. 72.6% for non-Latina White), or receive adequate ...

Summary: The goal of this clinical trial is to evaluate the use of the Plexaa preconditioning device (BLOOM43) in transgender and non-binary patients undergoing gender affirming mastectomy. This study aims to understand a participant's experience of the device, including its usability and acceptability. Participants will use the device to precondition their right breast the evening before undergoing surger...

Summary: Over the past decades, interest in second breast-conserving therapy (BCT) has increased due to, among others, advancements in radiotherapy techniques. Preoperative partial breast irradiation (PBI) is an experimental treatment for patients with low-risk primary breast cancer. This approach can downstage the tumor, and may possibly reduce toxicity and improve cosmetic outcomes compared to postoperat...

Summary: Research Purpose The present study is designed to generate the strongest evidence available on the role of robotic surgical systems in breast cancer surgery and to elucidate the clinical value of immediate breast reconstruction (IBR) conducted in conjunction with robot-assisted nipple-sparing mastectomy (RNSM). Study Design Overview This study is a prospective, multicenter, randomized clinical tri...

Summary: To de-escalate radiation therapy in women with breast cancer.

Summary: This is a prospective study comparing partial mastectomy performed with routine cavity shave margins and Savi Scout® localization to partial mastectomy performed with selective margins and Savi Scout® localization. The primary objective is to determine the difference in positive margin rate between the two methods. The secondary objectives are to determine the differences in the rate of re-excisio...

Summary: The researchers are doing this study to see if the combination of surgery, locoregional radiation therapy, SBRT (stereotactic body radiation therapy), and the usual approach is more effective in treating oligometastatic HER2-positive breast cancer than the usual approach alone. The researchers will also study the side effects of the study treatment.
