• Radiation: omit of IMI group — clincial high risk breast （≥2 risk factors）patients with 18-gene low risk an indication for regional nodal irradiation will received 2 Gy for 25 fractions to chest wall or whole breast and supraclavicular lymph nodes irradiation and sequential tumor bed boost of 2 Gy for 5 fractions following breast conserving surgery.
• Radiation: IMI group — clincial high risk breast （≥2 risk factors）patients with 18-gene low risk an indication for regional nodal irradiation will received 2 Gy for 25 fractions to chest wall or whole breast and supraclavicular lymph nodes irradiation and sequential tumor bed boost of 2 Gy for 5 fractions following breast conserving surgery.

Primary Outcomes

• 2-year event-free survival (2 years)

About This Study

This study is a prospective, open-label, multicenter, randomized controlled Phase III clinical trial. Building upon anti-HER2 targeted therapy combined with endocrine therapy, the addition of CDK4/6 inhibitors has demonstrated greater clinical benefits for advanced TPBC patients. This study aims to investigate the efficacy and safety of CDK4/6 inhibitor combination with standard adjuvant endocrine therapy in HR+/HER2+ early breast cancer patients.

Design

Interventions / Regimen

• Drug: Endocrine Therapy (Tamoxifen, Anastrozol, Letrozole, Exemestane) — Standard endocrine therapy
• Drug: Standard endocrine therapy combined with CDK4/6 Inhibitor — CDK4/6 inhibitor therapy for 2 years in combination with standard endocrine therapy

Primary Outcomes

• 5-years Invasive disease free survival (5 years)

About This Study

RATIONALE: It is now standard for most breast cancer patients with 1-2 positive sentinel nodes to avoid completion node dissection when eligibility criteria from the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial are met. The National Comprehensive Cancer Network (NCCN) recently proposed to extend this indication to patients that present with biopsy proven node positive disease if only 1 or 2 suspicious nodes are found on imaging, these positive nodes are not palpable clinically, and the other eligibility criteria from the Z0011 study are otherwise met. However, this recommendation is based on an expert consensus and no study has yet confirmed the optimal method to stage the axilla in this patient population. PURPOSE: Evaluate the technical success rate and accuracy of sentinel node biopsy (SNB) and the potential benefits of clipping and removing the biopsy proven node using radioactive seed localisation (RSL) (SNB+RSL = Targeted Axillary Dissection (TAD)) in patients with biopsy proven positive nodes, limited nodal disease in imaging and clinically negative axillary examination.

Design

Interventions / Regimen

• Procedure: Targeted Axillary Dissection — Sentinel Node Biopsy (SNB; using Tc99 +/- Blue dye) + Radioactive Seed Localisation (RSL) of clipped node using I125 seed = Targeted Axillary Dissection (TAD)
• Diagnostic Test: Ultrasound of the axilla — Prospectively recorded preoperative ultrasound of the axilla. Number of suspicious nodes recorded. Biopsy and clipping of the positive node.

Primary Outcomes

• Reduction in recommended completion node dissection rate (CND) with the use of Targeted Axillary Dissection (TAD) vs. Sentinel Node Biopsy (SNB) alone. (1 month)

About This Study

It is believed that the use of organoids derived from male breast tumors can be of fundamental support for the definition of the molecular mechanisms underlying the onset of the tumor. Furthermore, the development of such preclinical models could be of significant support for the identification of specific personalized and ad hoc therapeutic treatments for male pathology.

Design

Primary Outcomes

• Tumor tissue samples collected (36 months)

About This Study

This is a multicenter, open-label, dose-finding trial using a backfill Bayesian optimal interval (BF-BOIN) design to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) for paclitaxel oral solution combined with anti-HER2 treatment. Eligible HER2-positive breast cancer patients receive 6 cycles of neoadjuvant THP regimen(paclitaxel oral solution + trastuzumab+pertuzumab) and are enrolled in three cohorts at oral paclitaxel dose levels 1-3 (125, 150, 175 mg/m²).

Design

Interventions / Regimen

• Combination Product: Paclitaxel oral solution plus Trastuzumab and Pertuzumab — Eligible patients in three cohorts receive 6 neoadjuvant THP cycles: paclitaxel oral solution at 125/150/175 mg/m² BID (D1, D8, D15), and dual anti-HER2 therapy - trastuzumab (8→6 mg/kg IV or 600 mg SC) and pertuzumab (840→420 mg IV), both Q3W - or, alternatively, the pertuzumab/trastuzumab SC fixed-dose combination (Phesgo; loading 1200/600 mg \[15 mL\], maintenance 600/600 mg \[10 mL\]), Q3W; all for 6 cycles.

Primary Outcomes

• Maximum Tolerated Dose(MTD) (Up to 24 weeks.)

About This Study

This study is a multicenter, observational, real-world investigation. The research plans to enroll 300 HER2-positive and HER2-low breast cancer patients who meet the inclusion criteria. All patients included in the analysis are currently receiving or are scheduled to receive a treatment regimen containing Trastuzumab-rezetecan. There are no restrictions on the treatment regimen, which is entirely based on the clinician's choice. The study aims to evaluate the efficacy and safety of the treatment regimen containing Trastuzumab-rezetecan. After completing screening examinations and assessments, eligible patients will enter the study treatment phase. They will receive the treatment regimen containing Trastuzumab-rezetecan and undergo follow-up visits according to the protocol. During the study treatment period, patients will undergo imaging and safety assessments as per clinical routine, with the investigator's assessment serving as the final result. Upon treatment completion or study withdrawal, corresponding safety examinations and imaging assessment data will be collected. For neoadjuvant patients, pathological complete response (pCR) will be assessed post-surgery by pathologists at the participating centers.

Design

Interventions / Regimen

• Drug: Trastuzumab-rezetecan Treatment Group — Trastuzumab-rezetecan: 4.8 mg/kg (for HER2-positive) or 6.4 mg/kg (for HER2-low) per treatment cycle of 21 days. The dosage is to be adjusted at the discretion of the investigator based on the actual clinical situation. All patients will receive treatment with a regimen containing Trastuzumab-rezetecan as determined by the investigator. The regimens for other concomitant medications will be selected by the treating physician based on the patient's individual circumstances.

Primary Outcomes

• Adverse events (AEs) (From the signing of the informed consent form until 30 days after the last dose)

About This Study

Patients treated for breast cancer with hormone therapy (HT) suffer from hot flashes. This side effect impacts treatment adherence. Indeed, approximately 50% of women take less than 80% of the prescribed dose, and up to 50% abandon their treatment before the fifth year of prescription, significantly increasing the risk of recurrence. Moreover, these hot flashes strongly impact the quality of life. According to the CANTO study, these hot flashes can persist up to two years after diagnosis, affecting social relationships, return to work, and physical and mental health. Some side effects resulting from HT (sleep disturbances, fatigue, hot flashes) could be alleviated by a non-pharmacological approach involving the patient. Our hypothesis is that a non-pharmacological solution, such as the use of self-hypnosis, could reduce hot flashes and the side effects related to HT or the perception thereof in patients treated for breast cancer. Consequently, this could improve the quality of life and lead to better treatment adherence. The principal objective is to evaluate the effect of daily guided self-hypnosis sessions in reducing hot flashes in patients with non-metastatic breast cancer receiving anti-aromatase hormone therapy. The secondary objectives are to evaluate : * Patient adherence to guided self-hypnosis via a digital solution * Quality of life * Sleep quality * Satisfaction with care * Usability of the digital tool The originality of this clinical trial is the proposal of self-hypnosis sessions over three weeks with three different themes using a digital solution.

Design

Interventions / Regimen

• Other: self-hypnosis sessions — 3 self-hypnosis sessions over 3 weeks, one session per week to be practiced daily

Primary Outcomes

• Hot Flash Score (HFS) (28 days)

About This Study

The study is being conducted to understand if the hemoglobin A1c, a measurement of control of blood sugars over a 3-month time, is valid in patients with Left Ventricular Assist Devices (LVADs) in place. To understand whether it is an adequate measurement, the investigators will compare the A1c to results from a continuous glucose monitor (CGM) measurement of blood sugars. By monitoring blood sugars continuously, the investigators will also assess whether they can get better control of blood sugars with a CGM, including avoiding low blood sugars.

Design

Interventions / Regimen

• Device: Freestyle Libre 3 Continuous Glucose Monitor (CGM) — Subjects will be provided a Freestyle Libre 3 CGM for monitoring of blood glucose levels throughout participation in the study (approximately 3 months). CGM data will be uploaded to the LibreLink app on a weekly basis for review of glucose control and consultation with a diabetes-trained provider for any values outside of normal ranges. Adjustments to diet and medication therapy (antihyperglycemic therapy) will be made during consultations to improve episodes of hypoglycemia or severe hyperglycemia that were observed.

Primary Outcomes

• Average glucose values based on continuous glucose monitoring (3 months)
• Estimated average glucose (eAG) values based on hemoglobin-A1c lab values (3 months)
• Estimated average glucose (eAG) values based on fructosamine lab values (3 months)

About This Study

The focus of this study is to test the efficacy of an 8-week, remotely delivered, positive-psychology-motivational interviewing (PP-MI) intervention, with additional twice weekly text messages for a total of 16 weeks (with interactive, algorithm-driven, goal-focused text messages in the final 8 weeks), compared to MI-alone, in a randomized trial of 280 individuals with type 2 diabetes and low baseline physical activity.

Design

Interventions / Regimen

• Behavioral: Positive Psychology + Motivational Interviewing — The 8-week PP-MI intervention focuses on enhancing well-being (through PP) and increasing physical activity (through MI). Each week, participants will complete a PP activity and work towards a physical activity goal, then complete a phone session with a study trainer. The PP portion of the program will focus on the cultivation of well-being through the performance of easy-to complete activities (e.g., using a strength in a new way) and review of the positive feelings they generate. The MI portion of the program will focus on assisting participants to improve physical activity levels, resolve ambivalence to behavior change, set realistic physical activity goals, problem-solve barriers, and identify resources to complete behavior change. Finally, participants will receive twice weekly text messages (for 16 weeks) to encourage completion of PP activities and engagement in physical activity.
• Behavioral: Motivational Interviewing — The 8-week MI-alone intervention focuses on providing education and enhancing motivation to engage in health behaviors (through MI). Each week, participants will complete an activity related to a health behavior (e.g., consider the pros and cons of behavior change, set a health behavior goal), then complete a phone session with a study trainer. This program will focus on assisting participants to improve health behavior adherence (including physical activity), resolve ambivalence to behavior change, set realistic health behavior goals, problem-solve barriers, and identify resources to complete behavior change. Additional time in MI-alone phone sessions will be spent on review of core MI skills, problem-solving of barriers, and discussion of resources. Finally, participants will receive twice weekly text messages (for 16 weeks) to encourage engagement in health behaviors.

Primary Outcomes

• Change from Baseline Moderate to Vigorous Physical Activity (MVPA) at 16 weeks (Measured for 7 days at baseline and 16 weeks)
