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.
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.
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.
The standard treatment for women with invasive breast cancer is local excision follow by whole breast radiation. The local recurrence rates are low, side effects are low, and the cosmetic outcome is excellent. The treatments, however, need to be given daily for 5 1/2 to 6 1/2 weeks, making the treatment difficult, particularly for the elderly and for women who need to travel long distances for the therapy. The goal of this study is to determine the toxicity and efficacy of giving the radiation in a shorter time, using higher daily doses of radiation. The risk of recurrence in the elderly population is lower, and since majority of recurrences occur close to the area where the tumor previously was, it is hypothesized that radiation to that area of the breast would be sufficient to obtain low risk of recurrence. When a smaller volume of tissue is treated, more radiation can be given daily, and therefore the treatment can be shortened. The risk of side effects increases as the dose per daily treatment increases. Therefore, the goal is to study the short term side effects, long term side effects, and cosmetic outcome of daily radiation using higher daily doses for shorter period of time. We will also follow the recurrence rate. Because less of the breast tissue will be treated, there may be a small increased risk of recurrence. Because the higher fraction size can result in more side effects we will be using intensity modulated radiation (IMRT). IMRT is the most advanced individually tailored radiation treatment technique that results in the least amount of side effects. It allows tight monitoring of the dose in the untreated breast. Seventy five women diagnosed with stage I breast cancer will participate. Participants must have a lumpectomy, clear margins and no lymphovascular invasion to be eligible. A treatment planning CT scan will be obtained. If the lumpectomy cavity can be clearly delineated, an IMRT plan will be generated with predefined strict dose requirement criteria. The patients will be treated once daily, 5 days a week, for a total of 10 treatments (instead of standard 28-33). The patients will be evaluated for toxicity weekly during the treatment, and weekly for additional 4 weeks. At each of these evaluations, they will fill out a short 10 minute questionnaire detailing their side effects. Follow-up will continue every 3 months for 3 years, and every 6 months for 2 more years. At each of these follow-ups a short questionnaire will be filled out by the patients detailing any toxicity, as well as their perception of the cosmetic outcome. A cosmesis questionnaire will be also be filled out by the evaluating physician before radiation, at 6, 12, 18, and 24 months, and yearly for 3 more years. A total of 5 years of follow-up is planned. Participants will also have the option of consenting to the photograph portion of the study. Those who do will have photographs taken of their breasts (excluding faces) at the time they complete the cosmetic questionnaire, to evaluate the cosmetic outcome.
