Filter by:There are controversies about breast implant-based reconstruction techniques. Our center pioneered single-port insufflation endoscopic nipple-sparing mastectomy (SIE-NSM) combined with stage I prosthesis reconstruction. The study's primary objective is to compare single-port endoscopic NSM combined with pre-pectoral breast reconstruction to the subpectoral breast reconstruction group regarding breast satisfaction. This study is an ambispective cohort study. The study will be conducted at Beijing Friendship Hospital, affiliated with Capital Medical University. Patients will be enrolled retrospectively from January 2014 to March 2022 by reviewing the medical records and recruited prospectively from March 2022 to March 2025. The two cohorts are the pre-pectoral breast reconstruction cohort and the subpectoral breast reconstruction cohort, both following single-port insufflation endoscopic nipple-sparing mastectomy. The primary outcome of this study is postoperative breast satisfaction, which the BREAST-Q score will measure. The different variables will be compared using the Χ2 test for categorical variables and the Mann-Whitney test for continuous variables.
The aim of our study is to examine the cryoimmunologic response and its mechanisms induced by US-guided cryoablation of small breast tumors (<2 cm) not eligible to neoadjuvant therapy. We will recruit 30 women who will undergo cryoablation and their results will be compared with a control group of 30 women, who will follow the same therapeutic pathway without performing cryoablation. All recruited patients will undergo an enrollment check, pre-cryoablation breast MRI and blood test to assess immune response, breast cancer US-guided cryoablation, post-cryoablation breast MRI and the same blood test to evaluate immunologic response. Within 21 days all patients will undergo breast surgery, with immuno-histopathological analysis on surgical specimen. At least 10 days after surgery the patient will undergo clinical breast examination, blood test to assess immune response and patient satisfaction questionnaire. Cryoablation treatment will be performed using a 14G cryoprobe under us-guidance for visualization of the ice ball surrounding the lesion. The ultrasound guide is used to ensure that the action affects the entire tumor and that therapeutic temperatures are reached in every part of the tumor. Pre- and post- cryoablation breast MRI will be performed on a 3T magnet to assess cryoablation rate of success. Artificial intelligence algorithms will also be used for this purpose. Cryoablation treatment efficacy will also be evaluated with ultrasound. The immunological fitness of cancer patients will be studied by flow cytometry, evaluating the presence of cytokines/chemokines relevant during anticancer immune response/tumor progression and for the presence of molecules released by cells during an immunogenic cell death. The goal of our study will be to demonstrate that cryoablation of breast cancer can induce an antitumor immune response. Therefore this approach could become an additional tool in the oncological treatment of breast cancer.
This research is being done to assess whether an exercise intervention with protein intake support vs a health education and support program will make it easier for women age 65 or older who are receiving chemotherapy for breast cancer to receive all of their planned chemotherapy according to schedule and at the planned dose.
The standard treatment for breast cancer when cancer cells were found near or within the margins of the tissue that is removed during breast surgery, is radiation of the entire chest wall. This may be considered overtreatment since the only reason for doing so is that cancer cells were near or in the margins of the breast tissue that was removed. In this study, the amount of radiation treatment will be limited to the area where the remaining cancer cells were found after surgery. The purpose of this study is to find out if partial chest wall radiation therapy is as good as whole chest wall radiation therapy in reducing the risk of breast cancer cancer coming back.
An explanatory study comparing complementary treatment to breast conservative surgery with radiation therapy DCIS, T1-T2 N0 M0 (AJCC v8) 1 week schedule vs 3.1 weeks standard schedule, in order to determine the equivalence of local tumor control, survival, acute and chronic toxicity. Shorter curse of radiation therapy may lead to similar local control of tumor cells and lower rates of toxicity than 3.1 standard treatment.
This Phase III Trial evaluates whether breast conservation surgery and endocrine therapy results in a non-inferior rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation with breast radiation and endocrine therapy.
This study will evaluate the local control, complication rates, cosmetic results, and quality of life between patients treated with a single fraction vs. five fractions of accelerated partial breast irradiation (S_APBI vs. F_APBI) when used as the sole method of radiation therapy.
Researchers think that exercise may be able to prevent cancer from coming back by lowering ctDNA levels. The purpose of this study is to explore how aerobic exercise (exercise that stimulates and strengthens the heart and lungs and improves the body's use of oxygen) can reduce the level of ctDNA found in the blood. During the study, the highest level of exercise that is practical, is safe, and has positive effects on the body that may prevent the return of cancer (including a decrease in ctDNA levels) will be found. Each level of exercise tested will be a certain number of minutes each week. Once the best level of exercise is found, it will be tested further in a new group of participants. All participants in this study will have been previously treated for breast, prostate, or colorectal cancer.
This research study involves pre-operative therapy that is specifically targeted for breast cancer in individuals with BRCA and PALB2 mutations. The names of the study drugs involved in this study are: - Niraparib (Zejula) - Dostarlimab
This is a prospective, single arm, open-label, unicenter, exploratory study in women with primary operable HER2-positive, HER2-enriched/ERBB2-high breast cancer according to PAM50 intrinsic subtype and a ERBB2 pre-defined cutoff (high vs low ERBB2 expression), to evaluate the omission of surgery and sentinel lymph node dissection in patients with HER2-E and ERBB2 high breast cancer who achieving a complete response following standard anti-HER2-based neoadjuvant therapy with paclitaxel/trastuzumab/pertuzumab. The primary trial objective is to estimate the loco-regional invasive disease-free survival at 3-year of patients who achieve a complete response based on imaging (i.e. Magnetic resonance imaging) and a stereotactic-guided vacuum-assisted breast biopsy, and omit loco-regional surgery.
