This will be a single-blinded study where participants are blinded to the suture type but the surgeon will draw a random, unmarked envelope containing the designated suture type at the start of the surgery. The patient population will be all patients undergoing breast surgery at the London Health Sciences Center (LHSC) - ie. University Hospital, Victoria Hospital and the Nazem Kadri Surgical Center, and St. Joseph's Hospital. Three (3) main procedure groups will be transgender gender-affirming top surgery, cisgender female breast reduction or augmentation (including healthy and cancer patients; subgroup analysis will be performed), and cisgender male gynecomastia surgery. The goal is n=180 patients, n=60 per type of suture with n=20 per type of procedure (totaling n=60 per type of procedure). NAC width for each breast will be measured intraoperatively, at 2 weeks postop, 6 weeks postop, 3 months postop, and 6 months postop. These measurements will be deidentified and logged into a secure data entry form. Information on whether a secondary outcome occurred (ie. infection, dehiscence, revision and nipple necrosis) will be logged in this form as well. Because the sutures will be kept non-visible under dressings until the clinical followup appointment 2 weeks postop, the patient will remain blinded as to the type of suture used on their NAC(s). At this point, absorbable sutures will have been largely dissolved and non-absorbable sutures will be removed.
This study aims to identify HER2-positive early-stage breast cancer patients who could benefit from neoadjuvant treatment using PHESGO™ (pertuzumab and trastuzumab) without chemotherapy. The approach involves utilizing specific biomarkers (HR and HER2 IHC status) to select participants whose tumors strongly rely on the HER2 pathway, potentially benefiting from a HER2-targeted approach without chemotherapy concurrently.

TUXEDO-4 is an international, multicentric, single arm, phase II study aiming to gather additional solid evidence of Trastuzumab-Deruxtecan (T-DXd) activity in patients with Human Epidermal Growth Factor Receptor 2 (HER2)-low breast cancer with active brain metastases. This study will analyze the efficacy of T-DXd as determined by overall response rate (ORR) at any timepoint as judged by best CNS response according to RANO-BM criteria.
Obesity could become the first evitable cause of breast cancer in the near future. Due to the relatively slow rate of development in this field, greater efforts must be applied in this area. The HYPOTHESIS of this work is that "a therapy to lose weight in breast cancer women with obesity during the oncological treatment could contribute to slowing carcinogenesis, and to improve the response to the chemotherapy, survival and prevent future recurrences by erasing deleterious epigenetic marks". A group of breast cancer women with obesity (n=90) will be treated to lose weight during the oncologic treatment with a low calorie-ketogenic diet or a group educational intervention program of healthy lifestyle. The reversibility of the obesity-related breast cancer epigenetic signatures (EPIC array and pyrosequencing) and other molecular features (QRTPCR, ELISA assays) in blood leukocytes and plasma and the progression of disease will be compared with an obesity (n=30) and normalweight (n=30) group under conventional anticancer therapy. A matched-group of tumor-free women (n=60) with obesity will be also treated to lose weight with the same nutritional interventions and compared with tumor-free women with normal weight (n=30) in order to evaluate the potential preventive function of weight loss therapies on cancer-related odds. The outcomes of this project will directly benefit overweight and obese patients from healthcare systems, and also to have an economic value supporting pharmaceutical and food industry companies in the design of innovative treatments, useful biomarkers and preventive tools.
When we talk about early identification, we are talking about an ALREADY EXISTING INJURY, triggering a change in the patient's quality of life and a projection of future costs for the health system. INNOVATIVE ASPECT: While screening mammography identifies an existing lesion, VTM could: Make an early diagnosis before the formation of a visible or palpable tumor mass; Check the metabolic activity in suspicious lesions identified by other diagnostic methods; Demarcate tumor range and tumor similarity from a distance in breast cancer. Regarding the Risk x Benefit:There are no medications incorporated, associated or administered by the equipment; There is no ionizing radiation incorporated or delivered by the equipment; There are no contraindications for the use of the equipment by the patient (Non-ionizing infrared radiation, without contrast or contact); Audience destined to operate the equipment: Physician / Radiologist with training Therefore, the research in question is of great relevance for such a debilitating health problem for the patient and for the health system.
Breast cancer is the top one incidence of cancer in women. Whole breast radiation therapy plays an indispensable role in the course of breast cancer treatment, and the radiation dermatitis is the major side effect affected quality of life. Radiation dermatitis can be divided into acute and chronic. Severe acute radiation dermatitis affects the quality of life of patients during the course of treatment, and may cause treatment interruption and affect the efficacy. Chronic radiation dermatitis may cause irreversible skin problems, and lead to so-called "radiation-irritated skin" (radiation-irritated skin) seriously affects the quality of life of breast cancer patients after treatment. This study will enroll 30 breast cancer patients who received whole breast radiation therapy after breast conserving surgery. Subject will receive FR-101 chest dressing and be instructed to use the product on the target skin area accepted radiation therapy once every 2 days, taking care of avoiding applications from 1 to 4 h before treatment to prevent "Build-up" effect. Subjects will need to come back to clinics for assessment weekly during radiotherapy, 2 weeks after radiotherapy, and 6 weeks after radiotherapy. The evaluation includes physical examinations, questionnaire surveys, skin observation and measurements, and photographs. The total study time is at least 3 months. The target area of radiation-irritated skin condition will be observed and graded according to CTCAE rate. The skin physiological parameters will be detected by MoistureMeter SC, Vapometer, SkinColorCatch and HX-YL001 infrared thermometer. Statistical analysis of skin physiological parameters is used to evaluate the efficacy of FR-101 chest dressing on the prevention of acute radiation dermatitis after radiotherapy.
In sub-Saharan Africa, breast cancer patients often present with advanced disease. In my previous research which evaluated over 600 patients from a prospective institutional data base, about 64% of women with a new diagnosis of breast cancer presented with locally advanced disease, including clinically positive axillary adenopathy. Our data also suggests that similar to African American women, triple negative breast cancer (TNBC) is common in Nigeria (43.5%). The overall goal of the project is to evaluate the ability of existing technology in Nigeria to safely de-escalate axillary surgery in the management of locally advanced breast cancer patients. Currently, the standard-of-care for breast cancer patients with palpable axillary adenopathy (clinical N1 disease without evidence of distant metastases) at presentation in Nigeria is neoadjuvant systemic therapy followed by a modified radical mastectomy. This includes a complete axillary lymph node dissection (ALND). However, data from high-income countries however show that up to 85% of patients initially presenting with cN1 disease can be converted to cN0 (i.e. no palpable adenopathy) following NAC. These patients can thus safely undergo sentinel lymph node biopsy (SLNB) with up to 50% of these having pathologic complete response in the lymph nodes. In this patient population, both methylene blue and radio-isotope localization with Tc-99 sulphur colloid are required to ensure adequate performance of the SLNB to stage the axilla(i.e. false negative rate ≤10%). Although widely available in high-income countries, radio-isotope localization is not readily available in Nigeria. This project will explore an alternative to dual agent SLNB localization using readily available resources and multi-disciplinary collaboration in a lower-income environment. De-escalation of axillary surgery in high-income countries has significantly decreased operative morbidity and improved patient reported outcomes without compromising survival. However, context specific research and data from resource limited environments is needed to translate the benefit of de-escalation to sub-Saharan Africa.
Exploring the Efficacy and Safety of Different Systemic Treatment Regimens after CDK4/6i Progression in the Real World has significant implications. This study is an observational, real-world study. It plans to include over 300 eligible HR+/HER2- metastatic breast cancer patients who are currently receiving or planning to receive endocrine therapy regimens containing CDK4/6 inhibitors. This study is a single-arm, non-interventional study that evaluates the efficacy and safety of the first-line treatment regimen, which includes CDK4/6 inhibitors combined with endocrine therapy, based on clinical guideline consensus. After disease progression on first-line treatment, the second-line systemic treatment regimen (including but not limited to switching to another CDK4/6 inhibitor combined with endocrine therapy, other types of endocrine therapy, chemotherapy, targeted therapy, etc.) will be chosen by the physician, and the efficacy and safety of subsequent treatment will be evaluated. Additionally, peripheral blood ctDNA testing will be used to assess changes in baseline and progression-related biomarkers, including ESR1, PI3KCA, FGFR1, PTEN, among some patients.
