NCT06419621
This multicenter, randomized, double-blind study will evaluate the safety and efficacy of PM8002 in combination with Nab-Paclitaxel compared with placebo combined with Nab-Paclitaxel as first-line treatment in inoperable locally advanced/metastatic triple-negative breast cancer(TNBC)
NCT06868758
This study aims to evaluate the predictive value of the tumor vascular normalization score for the efficacy of neoadjuvant therapy in HER-2-positive breast cancer and explore its potential as a predictive biomarker. Through longitudinal observation of HER-2-positive breast cancer patients receiving standard treatment, we will analyze the correlation between vascular normalization scores and treatment responses (including objective response rate \[ORR\] and pathological complete response \[pCR\]) to optimize individualized therapeutic strategies. Additionally, an exploratory investigation will assess the impact of ginsenoside-containing formulations (e.g., Jinxing Capsule, Shenyi Capsule, Yiqi Jianpi Oral Liquid) on tumor vasculature and neoadjuvant therapy outcomes in HER-2-positive breast cancer, providing scientific insights for complementary therapeutic interventions.
NCT06866093
The goal of this observational-retrospective study is to learn about the long-term effects of a lifestyle intervention inclusive of dietary counselling and physical activity advice, on body weight in female breast cancer survivors who took the intervention in previous years compared to those who did not take it. The main question it aims to answer is: Does a long-term lifestyle intervention help to control body weight 5 years after breast cancer diagnosis? Participants are asked to answer online survey questions about their anthropomethry, clinical conditions, socio-economical status, dietary habits, physical activity levels, quality of life, sleep quality and pshycological distress.
NCT06868017
The purpose of this study was to explore the efficacy and safety of initumab combined with pyrrotinib and chemotherapy for 4 cycles and 6 cycles of neoadjuvant therapy for HER2-positive breast cancer, and to explore the efficacy and safety of continued use of initumab combined with pyrrotinib in pCR patients. This study adopted A prospective, randomized controlled, open-label design, and selected eligible subjects to be randomly divided into cohort A and Cohort B. Cohort A will receive initumab at initial load dose of 8mg/kg and maintenance dose of 6mg/kg intravenously on the first day of every three weeks for a total of 4 doses. Pyrrotinib 400mg orally once daily; Combined chemotherapy drugs (not limited, according to the actual clinical selection), a total of 4 cycles of administration. After surgery for breast cancer, initumab + pyrrotinib was selected as adjuvant therapy for pCR patients after surgery for 1 year (neoadjuvant therapy + adjuvant therapy for a total of 1 year, a total of 13 cycles of adjuvant therapy), and non-pCR patients were selected by doctors. Cohort B will receive initumab at initial load dose of 8mg/kg and maintenance dose of 6mg/kg intravenously on the first day of every three weeks. Pyrrotinib 400mg orally once daily; Combined chemotherapy drugs (not limited, according to the actual clinical selection), a total of 6 cycles of administration. After surgery for breast cancer, initumab + pyrrotinib was selected as adjuvant therapy for pCR patients after surgery for 1 year (neoadjuvant therapy + adjuvant therapy for a total of 1 year, and adjuvant therapy for a total of 11 cycles), and non-pCR patients were selected by doctors.

NCT06497660
As is well known, perioperative hemodynamic fluctuations, such as decreased blood pressure and heart rate, and cardiac dysfunction, are common complications after anesthesia. General anesthetics such as propofol and sufentanil can inhibit the central nervous system, reduce cardiac excitability and myocardial contractility, dilate peripheral blood vessels, and have a high incidence of hypotension, especially during anesthesia induction, which is particularly common in the elderly and those with underlying underlying diseases before surgery. However, the current research on the impact of neoadjuvant chemotherapy on perioperative cardiac function in patients is not specific, and there is no unified anesthesia strategy for these effects during the perioperative period. Therefore, this study aims to explore: 1. the effect of neoadjuvant chemotherapy on perioperative cardiac function in patients; 2. Improve the anesthesia plan and further explore new strategies for perioperative organ protection for such patients. The research design is a prospective, randomized, controlled trial.
NCT06857305
Eribulin is a soft spongin-like inhibitor of mitotic microtubule dynamics in cells. From the evidence of efficacy, the STUDY 305 and STUDY 301 studies suggest that eribulin improves PFS and OS in patients with breast cancer. Eribulin has a good safety profile with a low incidence of patient-perceivable adverse effects, with myelosuppression being the main adverse effect, and neutropenia, anemia, and also fatigue being the most common adverse effects. However, serious neutropenia, may result in delayed dosing, dose reduction or discontinuation in some patients. In studies of standard regimen therapy with eribulin, grade 3-4 neutropenia occurred in approximately 45% of patients, of which approximately 25% required dose adjustment or discontinuation of therapy, which has become an urgent clinical problem in the treatment of eribulin. Therefore, a modified bi-weekly regimen of eribulin (1.4 mg/m2 intravenously on days 1 and 15 of a 28-day cycle), based on the standard regimen (1.4 mg/m2 intravenously on days 1 and 8 of a 21-day cycle), is expected to improve the safety of eribulin administration without compromising efficacy, in order to minimize dose reductions of the medication and interruptions of therapy, thereby improving patients' quality of life. There is still a lack of head-to-head studies on the efficacy and safety of the combination of eribulin standard regimen and biweekly regimen in HER2-negative advanced breast cancer, and the treatment data in the Chinese population need to be further explored. The aim of this study is to explore the efficacy and safety of eribulin biweekly regimen compared with the standard regimen in patients with locally recurrent or metastatic HER2-negative breast cancer, and to provide a clinical evidence-based basis for the optimization of eribulin treatment regimen.
NCT02240472
Since the introduction of sentinel node biopsy in breast cancer, it has become clear that its use is reliable and reproducible. Today, it is clinical routine to not remove further lymph nodes from the axilla (arm pit) in case the sentinel node (which is the first lymph node/s reached by lymphatic flow from the breast) is free of tumor deposits. It is also routine to leave remaining lymph nodes behind in case the sentinel node contains a minimal cluster of tumor cells, called isolated tumor cells (formerly submicrometastasis). Even in slightly larger tumor deposits, so called micrometastasis (up to 2 mm in size), it has been shown that a completion axillary clearance (removal of further lymph nodes from the arm pit) does not contribute to a better survival. Data from a randomized study indicate that it seems safe to omit axillary clearance even if the sentinel node biopsy shows up to 2 nodes with tumor deposits over 2 mm in size (macrometastasis). These studies have changed clinical practice in many countries, however, it is still debated whether it is safe to omit axillary clearance in the case of sentinel node macrometastasis due to under-recruitment in the aforementioned study. The rationale for omitting extensive axillary surgery is the avoidance of postoperative morbidity such as arm lymphedema, loss of sensation, pain and swelling. The hypothesis is that refraining from axillary clearance in breast cancer patients with 1-2 sentinel nodes with macrometastasis will not worsen breast cancer-specific survival by more than a maximum of 2.5% after 5 years. This study is a prospective international randomized trial including 3500 patients. Breast cancer patients without signs of axillary nodal involvement will be eligible for sentinel node biopsy. Those who are found to have up to two sentinel node containing macrometastasis will be informed about this trial Those wishing to participate will be randomized to either undergo further axillary surgery (clearance) or not. Outcome measures are breast cancer-specific survival, disease-free survival, axillary recurrence rate and overall survival.
NCT05559411
In the last decades, the proportion of breast cancer (BC) patients receiving breast-conserving surgery has increased steadily, reaching 70-80% in developed countries. Since positive resection margins are strongly associated with local recurrence risk, the goal of breast surgery is the complete tumor removal and most national and international guidelines recommend re-operation, either in form of re-excision or mastectomy, until clear margins have been reached. Re-operation rates vary widely, with population-based studies reporting a range of 15-35%, and the necessity for a second surgery can lead to increased patient anxiety, a delay in start of adjuvant treatment, worse cosmetic outcome and increased complication rates and costs. Therefore, re-operation rate has been included as a quality indicator in several countries. Several imaging-guided techniques have been developed to guide removal of non-palpable breast lesions, the oldest one being preoperative wire placement under ultrasound or mammographic guidance, usually followed by radiography or ultrasound of removed tissue. Newer techniques, such as intraoperative ultrasound (IOUS), radioguided occult lesion localization (ROLL), radioactive seed localization (RSL), radar reflector-localization (RRL), magnetic seed localization (MSL), and radiofrequency identification (RFID) tags have been introduced as an alternative to wire-guided localization (WGL). To date, comparative data on the rates of successful lesion removal, negative margins, re-operation rate and patient's comfort depending on the localization technique used are limited. Further, since some of these studies were funded by the manufacturer of the marker examined, a potential bias cannot be excluded. In the vast majority of the available studies, the patient's perspective with regard to discomfort and pain level has not been evaluated. The aim of the proposed study is to comparatively evaluate different imaging-guided localization methods used for surgical removal of malignant breast lesions with regard to oncological safety and patient-reported outcomes.
NCT04246671
A Phase 1 open label trial of intravenous administration of TAEK-VAC-HerBy vaccine in patients with advanced brachyury and/or HER2- expressing cancer. The study will be completed in 2 stages. In Stage 1 patients will be enrolled and treated according to a 3+3 dose escalation scheme. Up to 4 dose levels will be explored to determine the recommended dose of TAEK-VAC-HerBy for Stage 2 of the trial. Stage 2 will enroll either chordoma patients for treatment with TAEK-VAC-HerBy alone, or HER2- positive breast cancer patients for combination treatment of TAEK-VAC-HerBy vaccine and therapeutic HER2 antibodies (trastuzumab). Patients in both stages will receive TAEK-VAC-HerBy intravenously, every three weeks, three administrations in total.

NCT06168825
The goal of this study is to learn if the Mind Over Matter (MOM) Intervention, a 5-week group program, can help Black and African American women deal with the fears, worries and sadness that often accompany cancer diagnosis and treatment. The main question this study aims to answer is: • Whether the MOM Intervention is feasible and acceptable among Black and African American women. We would also like to find out if: * The MOM Intervention decreases anxiety, depression and physical symptom severity for Black and African American women. * The MOM Intervention is culturally and linguistically appropriate, and identify barriers, strengths, and areas of improvement. Participants will: * Attend a Pre-Program Orientation * Attend 5 weekly MOM Sessions * Complete 2 questionnaires (one will be given before the first MOM Session begins, and the other will be given after the last MOM Session) Participants also have the choice to attend an optional Focus Group, which will be offered after the last MOM Session. Please note, this entire Intervention will be offered online. There will be no in-person sessions or visits.
NCT05959811
Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect in breast cancer patients with completion of chemotherapy, and that is characterized by associated clinical symptoms such as pain, tingling, numbness, and paresthesia etc. CIPN also interferes with patients' functions of daily living and leads to chronic functional decline and a reduced quality of life. Meridian yoga is beneficial to the treatment of patients with peripheral neuropathy and the improvement of their quality of life.
