The goal of this clinical trial is to evaluate the safety and feasibility of methylene blue single tracer-based extensive sentinel lymph node biopsy (ESLNB) and provide evidence for simplifying surgical procedures on the basis of ensuring axillary safety, as well as clarify the incidence of postoperative upper limb lymphedema in female patients with axillary node-positive breast cancer who achieve clinical axillary node negativity after neoadjuvant therapy. The main questions it aims to answer are: * What is the false negative rate of methylene blue single tracer-based extensive sentinel lymph node biopsy in the above-mentioned breast cancer patients? * What are the false negative rate and detection rate of methylene blue single tracer-based conventional sentinel lymph node biopsy * What is the incidence of upper limb lymphedema within 2 years after surgery in these patients? Participants will: * Undergo strict screening to confirm eligibility for the trial and sign an informed consent form * Receive a complete standard neoadjuvant therapy for 6 or 8 cycles as required * Undergo personalized breast surgery combined with methylene blue single tracer-based ESLNB plus axillary lymph node dissection * Accept pathological evaluation of the number of lymph nodes and metastatic lymph nodes in each resected part after surgery * Receive adjuvant therapies such as targeted therapy, endocrine therapy or local radiotherapy in accordance with clinical guidelines * Complete regular follow-up for 2 years after surgery (once every 6 months), including physical sign checks, surgical site evaluations, and upper limb circumference measurements to assess lymphedema
This is a first time in-human (FTIH) study designed to investigate the safety, tolerability, pharmacokinetics (PK), and immunogenicity of remzistotug in participants with select loco-regionally recurrent solid tumors or metastatic solid tumors where curative or standard treatment options have been exhausted.
The purpose of this study is to determine if the radiotracer, \[68Ga\]Ga-ABY-025, used for PET imaging can help us better identify and visualize lesions or tumors, in patients who are receiving standard of care therapy HER2+ cancers.
This is an observational study to validate target axillary dissection (TAD) in locally advanced tumors (cN2 and/or cT4).

This is a a multicenter Phase II clinical study investigating efficacy of pyrotinib combined with dalpiciclib combined with letrozole in ER-positive and HER2-positive advanced breast cancer patients. The sample size is 63.
The advances in early detection coupled with improvements in treatments have led to an ever increasing number of breast cancer survivors. New methods to improve outcomes, including strategies aimed at improving the quality of life and reducing the risk of other diseases, may complement the currently available treatment options. In particular, interventions targeting diet, weight and physical activity can reduce the risk of cancer occurrence, prevent cancer recurrence, and improve survival and the quality of life.This cross-sectional, prospective, observational study aims at evaluating dietary habits and nutritional knowledge in patients with early hormone receptor positive and hormone receptor negative breast cancer.
This is a single institution, prospective observational clinical trial for women with mammographically identified calcifications that may represent ductal carcinoma in situ (DCIS). The purpose of this study is to determine whether quantitative, multiparametric breast MRI performed prior to surgical resection can biologically characterize this common pre-invasive malignancy, ductal carcinoma in situ (DCIS), which typically presents in asymptomatic women as suspicious calcifications on mammography.
The purpose of this study is to better understand the genetic causes of cancer and the inherited tendency to develop cancer. To accomplish this, blood specimens and/or saliva samples and/or tumor and normal tissue blocks from patients and families of patients with cancer will be collected. Blood specimens will be frozen and stored for analysis at a later date. Tumor tissue and normal tissue will be stored for analysis at a later date. In order to perform this study, patients and members of their families will be asked to provide blood samples and/or saliva samples. Individuals will be asked to provide a history of cancer in their relatives at the time the blood sample is given. No relatives will be contacted before they have been asked by a family member if they wish to participate in this study. If they do wish to participate, the relatives should indicate this by returning the "Family Member Consent for Contact Form" After we receive this form, arrangements may be made for the family member to send in a blood and/or saliva sample or to come in person to provide the sample to us. Except for family history, no medical information provided by one member of a family will be discussed with other family members. At the end of this form, we will also ask for your permission to be contacted in the future to discuss information about your health, additional research with your samples and/or certain research findings possibly related to your sample.
The incidence of breast cancer and its mortality are reduced thanks in particular to early detection. Often performed after a screening test, stereotactic macrobiopsies are used to characterize abnormalities detected on mammography. This anxiety-inducing and painful examination leads to significant physiological and psychological modifications for these women who logically apprehend the realization of this act. Faced with this observation, investigators wondered what could be done to improve the experience of the patients during this examination. Investigators were interested in hypnosis because its effectiveness as a complementary practice has been validated by numerous studies with benefits on pain and stress management. However, today, there are no convincing results confirming which hypnosis method would be the best to manage patients' anxiety and pain during this examination.
Breast cancer surgery that includes removal of lymph nodes from the armpit (axillary lymph node dissection) can disrupt normal lymphatic drainage and may lead to arm swelling, known as lymphedema. This condition can cause discomfort, limit arm function, and reduce quality of life. Patients with a higher body mass index and those who receive regional lymph node radiation are at particularly high risk. This study aims to evaluate whether a preventive surgical technique, called axillary reconstruction using a pedicled lateral chest wall lymph-adipofascial flap, can reduce the risk of developing arm lymphedema after breast cancer surgery. During standard breast cancer surgery with axillary lymph node dissection, a small flap of tissue containing fat, fascia, and lymphatic tissue from the lateral chest wall is rotated into the axillary area to fill the surgical space and support lymphatic drainage. This is a prospective, single-arm Phase II clinical study. Participants will be followed for up to 24 months after surgery to assess the occurrence of arm lymphedema, changes in arm volume and bioimpedance measurements, quality of life, and surgery-related complications. The results of this study may help determine whether this simple and widely applicable technique can safely reduce the risk of lymphedema in high-risk breast cancer patients.
The trial aims to investigate the use of superparamagnetic iron oxide (SPIO) nanoparticles as a tracer for delayed sentinel lymph node dissection (d-SLND) in patients where upfront axillary surgery (SLND) is oncologically deemed unnecessary and should be avoided. This includes but is not limited to patients with a preoperative diagnosis of ductal cancer in situ of the breast (DCIS), an unclear BIRADS 4-5 planned for diagnostic excision or women planned for risk reducing mastectomy. SPIO is injected in the primary operation, and should final specimen pathology demonstrate invasive breast cancer, only then is an operation in the axilla (d-SLND) performed.
This research is a continuation of a usability study with the MARVIN chatbot. The investigators aim to adapt the MARVIN chatbot to open it to other health domains (e.g. breast cancer) and populations (e.g. pharmacists). Therefore, this protocol constitutes a master research protocol that will englobe different research projects with individual chatbots. The investigators adopt an adaptive platform trial design, which will allow flexibility in handling multiple interventions adapted to different populations while retaining the characteristics of a platform trial design allowing early withdrawal of ineffective trial arms based on interim data (implementation outcomes) and introduction of new trial arms.
This study aims to evaluate the efficacy and safety of capecitabine as the only adjuvant chemotherapy drug in patients with low-risk early triple-negative breast cancer who have received adequate local treatment. Patients meeting the inclusion criteria will receive capecitabine metronomic therapy for one year.
This phase I trial studies the side effects of vaccine therapy and pembrolizumab in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment, that have failed prior therapy, and that cannot be removed by surgery. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Giving vaccine therapy together with pembrolizumab may be a better treatment in patients with solid tumors.
This trial plans to enroll many patients with advanced solid tumors to complete GK01 cell transfusion, including but not limited to advanced gastric cancer, esophageal cancer, cervical cancer, triple-negative breast cancer, and non-small cell lung cancer. For patients with advanced solid tumors eligible for inclusion, autologous tumor-reactive T cells (experimental drug GK01) were cultured and prepared, and a certain dose of GK01 cells was given according to the cell transfusion plan, and the safety and tolerability of the patients after transfusion were observed. Exploratory evaluation of pharmacokinetic/pharmacodynamic profiles following reinfusion and initial evaluation of efficacy of investigational drug GK01 cells according to RECIST 1.1 criteria.
The primary objective of this study is to evaluate the safety, tolerability, MTD and RP2D of LP-184 in patients with advanced solid tumors who have relapsed from or are refractory to standard therapy or for whom no standard therapy is available.
