Filter by:This is a prospective and observational study, aiming to determine the detection rate and change of CtDNA in blood samples of cancer patients before, during and after neoadjuvant treatment. - Determine the rate of ctDNA positivity at the time before treatment, - Determine the rate of ctDNA positivity at the time during treatment, - Determine the rate of ctDNA positivity at the time after neoadjuvant therapy, whether there is a change in ctDNA expression of the study population during treatment. And aiming to investigate the relationship between ctDNA expression and MRI imaging with pCR response in neo-adjuvant therapy: - Correlation between ctDNA detection and pCR response. Determine the percentage of Positive Prediction Value - PPV, Negative Prediction Value - NPV of ctDNA, - Correlation between MRI imaging and pCR response. Determination of PPV, NPV of MRI - Combination of ctDNA detection and MRI imaging in the prognosis of pCR. Determination of PPV, NPV ratio of ctDNA combined with MRI.
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.
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.
This clinical trial implements a communication intervention to improve patient-oncologist communication in the outpatient medical oncology setting. A communication brochure called the ASQ brochure may help patients prepare for the doctor visit by thinking through the questions that patients and patients' family want to ask the doctor.
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 phase II trial investigates how well trastuzumab deruxtecan works alone or in combination with anastrozole in treating patients with HER2 low, hormone receptor positive breast cancer. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called deruxtecan. Trastuzumab attaches to HER2 expressed at low levels on cancer cells in a targeted way and delivers deruxtecan to kill them. Anastrozole works by decreasing estrogen production and suppressing the growth of tumors that need estrogen to grow. This study is evaluating how effective trastuzumab deruxtecan is at treating hormone receptor positive cancer cells that have low levels of HER2 expressed on them when given alone or in combination with anastrozole.
The purpose of this study is to determine how well participants with stage II-III HER2-positive breast cancer respond to pre-operative treatment using one of two different combinations of drugs. Drugs and Combinations used: - Paclitaxel, Pertzumab and Margetuximab (Margenza) - Paclitaxel, Pertzumab and Trastuzumab (Herceptin)
This is an extension study to provide adjuvant treatment with single agent Herceptin or TX05 and assess continued safety and immunogenicity in subjects with HER2-positive early breast cancer following neoadjuvant treatment and surgical resection in Protocol TX05-03.
