NCT06610097
The gut microbiome is made up of the microbes (such as bacteria, viruses, and other organisms too small to see with the naked eye) that live in the digestive tract and has been shown to be important in metabolizing food, extracting vitamins and nutrients from food, and maintaining a healthy gut lining. The gut microbiome plays an important role in overall health and has been shown to dynamically change in response to early-stage triple-negative breast cancer-directed therapies, which in turn has been associated with worse outcomes. As the gut microbiome can be further modulated with dietary changes during cancer treatment, it is an ideal potential modifiable risk factor in cancer patients. However, due to multiple confounding factors such as dietary intake, mood, and activity, its utility as part of the oncologic clinical assessment remains unclear. In this prospective randomized controlled study, the investigators propose to recruit up to 30 early-stage TNBC patients to randomize to a personalized nutritional intervention of a high-fiber diet coached by a registered dietician versus educational handout alone during neoadjuvant treatment. The investigators propose to study the gut microbiota through stool sample analysis among early-stage triple-negative breast cancer patients undergoing neoadjuvant (i.e. before surgery) chemotherapy +/- immunotherapy. The investigators will also study how the gut microbiota can be further modulated with a high-fiber diet, and the investigators hypothesize that a high-fiber diet may play a protective role in preserving gut microbial diversity. As part of the nutritional intervention, the investigators propose to administer nutritional counseling with a registered dietitian (RD) to increase fiber intake and tracking performance status, activity, and mood during neoadjuvant treatment. Finally, the investigators propose to survey participants after study completion through one-on-one interviews to determine whether participants experienced improved overall patient satisfaction in supportive care during their treatment.
NCT06941142
This study adopts multicenter/randomized trial design. It plans to enroll patients with HR- positive, HER2- negative advanced breast cancer who are resistant to (neo)adjuvant endocrine therapy. Dose-escalation and dose-expansion studies will be carried out to evaluate the safety, tolerability, and preliminary efficacy of sirolimus (albumin-bound) in combination with palbociclib and fulvestrant in this patient population.
NCT03328884
Multicenter open-label, phase II trial, to evaluate the efficacy and safety of nal-IRI in patients with HER2-negative breast cancer, who have documented Central Nervous System (CNS) progression following Whole Brain Radio Therapy (WBRT), Stereotactic Radiosurgery (SRS) and/or surgery, as determined by the Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria.
NCT06313983
The purpose of this study is to evaluate the effectiveness of Hemay022 combined with AI (exemestane or letrozole) in the treatment of ER+/HER2+ advanced breast cancer patients based on the progression-free survival (PFS) assessed by the independent review committee (IRC). The second purpose of this study is to evaluate the pharmacokinetics and efficacy of Hemay022 in combination with AI, and the safety of Hemay022 in combination with AI. The trial plans to recruit 339 subjects, who will be randomly divided into two cohorts (the experimental group is hemay022 combined with AI, and the control group is lapatinib combined with capecitabine). During the treatment period, imaging examinations and anti-tumor efficacy evaluations will be performed regularly until the subject develop disease progression or starts receiving other treatments or dies or refuses to come to the hospital for follow-up or the trial is terminated, etc.
NCT05086705
This trial studies how well EMBr Wave technology works in reducing hot flashes in women with a history of breast cancer. Hot flashes are a common symptom experienced by menopausal women. The standard treatment for hot flashes is hormone replacement therapy, however hormone replacement therapy cannot be used in women with a history of, or active, breast cancer. EMBr Wave is a personal heating and cooling device worn on the wrist. EMBr Wave may help reduce hot flash severity in women with a history of breast cancer.
NCT06339658
To validate the use of ICG as a tracer during TAD in patients with cN1 breast carcinoma after neoadjuvant chemotherapy.
NCT03077191
This is a homogeneous, single institution, observational, non-interventional, prospective study of 500 patients who will be treated according to the standard protocol of adjuvant hypofractionated radiotherapy after breast conserving surgery, at a total dose of 40 Gy/ 15 fr (5 fr/ week, 3 consecutive weeks). In addition to the regular follow up, the patients will respond to the quality-of-life questionnaires (QLQ) of the European Organisation for Research and Treatment of Cancer (EORTC), general, QLQ- C30, and specific for breast (BR), QLQ- BR23, at the first visit, at the end of radiotherapy and at the subsequent follow-up visits from 6 months up to 5 and a half years, to evaluate the quality of life during and after the treatment. The study also has a retrospective arm of approximately 3300 patients (number of patients and characteristics of disease expanded with the amendment presented to the Lombardia 1 Ethics Committee in May 22/2024), treated from January 2009, for whom disease control and toxicity will be evaluated.

The trial will open with a dose escalation followed by an expansion cohort at the identified dose. Dose escalation will be open to the enrollment of patients diagnosed with triple-negative breast cancer or ovarian cancer. Dose expansion will only be open to patients diagnosed with triple-negative breast cancer.
NCT06939049
The main objective of the SISTEMA project is to develop non-invasive diagnostic tests for the detection and quantification in blood of markers of Mesenchymal Epithelial Transition, a mechanism that characterises certain types of cancer such as breast and lung cancer. Cancer is still one of the leading causes of death in Western countries. In 2014, there were an estimated 1,665,540 new cancer cases and 585,720 deaths in the United States alone. The World Health Organisation (WHO) and Eurostat predict 1,323,600 deaths in Europe, a figure slightly down on previous statistics but still underlining the existence and seriousness of the problem. It is no coincidence that cancer is one of the main areas of investment in the European Horizon 2020 programme. In recent years, the hypothesis that the process of carcinogenesis is driven by the activation of a particular panel of genes/proteins that enable cancer cells to acquire malignant characteristics has become increasingly popular. This process goes by the name Epithelial Mesenchymal Transition (EMT) and characterises all human epithelial tumours. This process allows epithelial tumour cells to acquire mesenchymal characteristics giving them stem, invasive, and chemoresistant properties.
NCT06777420
Preoperative chemotherapy has been shown to be at least as effective as postoperative chemotherapy in breast cancer patients and has seen increased use over time. The decision regarding neoadjuvant treatment is complex, as various aspects need to be considered, and the patient's role in the decision-making process is central. The information provided by doctors to patients about preoperative treatment can be complicated, including details about treatment options, treatment plans, and side effects. If this information is not conveyed adequately, there is a risk of misunderstandings, which can lead to increased anxiety and stress for patients regarding their decisions. In oncology, question prompt lists (QPL) have been used as a tool to support patients by improving the information conveyed by doctors in various contexts where complex decisions need to be made. Studies have shown that QPL can facilitate better information exchange. However, their use in discussions about preoperative treatment for breast cancer patients has not been studied. Furthermore, evidence from randomized studies on the use of QPL in clinical practice is very limited. The aim of this study is to investigate whether the use of QPL during patient consultations involving discussions about neoadjuvant chemotherapy can improve information exchange in various aspects: understanding of the treatment; anxiety about the decision; participation in the decision-making process; patient-doctor communication; and decision-related conflict.
NCT06223698
Based on the risk of late recurrence in breast cancer patients with luminal disease with high-risk for recurrence, extended adjuvant endocrine therapy beyond 5 years is recommended as a valid treatment option. In premenopausal women at diagnosis converted to postmenopausal after the first five years of tamoxifen, two treatment strategies for extended adjuvant endocrine therapy are available, namely continuing with tamoxifen or switching to aromatase inhibitors (AI). No randomized evidence does exist and both treatment strategies are used in clinical practice. In postmenopausal women with higher recurrence risk initially treated with AI for five years, extended adjuvant therapy with additional two years of AI has shown to be as effective as additional five years of AI. However, no randomized evidence on whether a switching strategy of five-year extended tamoxifen is better compared to two-year extended AI is available. Both treatment strategies are used in clinical practice. The primary objective of this register-based randomized trial is to investigate the overall survival between patients treated with switching strategy for extended adjuvant endocrine therapy compared to continuing with the same treatment as the initial 5 years in two different clinical scenarios: * In premenopausal women at diagnosis who converted to postmenopausal after 5 years of tamoxifen. * In postmenopausal women at diagnosis.
NCT05304962
This is a phase I, First-in-Human (FIH), open-label study to evaluate the safety, tolerability, pharmacokinetic (PK) profile, and preliminary efficacy of RGT-419B administered orally as monotherapy OR in combination with Hormonal Therapy in subjects with HR+, HER2- locally advanced and unresectable (Stage III) or metastatic (Stage IV) breast cancer whose disease has progressed during prior therapy with an approved CDK4/6i plus hormonal therapy.
NCT06613230
The goal of this observational study is to learn if so called Volatile Organic Compounds (VOCs) in blood can be used for early diagnosis of ovarian cancer. The main question it aims to answer is: Can OC Detect, a new in vitro diagnostic instrument, distinguish between VOC patterns in blood plasma from women with ovarian cancer (especially in early stage) and VOC patterns in helthy women? Participants are previosuly diagnosed patients with ovarian cancer, who agreed to store their blood samples in biobanks for future medical research purposes. Healthy female blood donors serve as benign control blood samples.
NCT06931548
There is currently no consensus on the "gold standard" for Implant-based Breast reconstruction. In the United States, more than half of all breast reconstructions are performed using acellular dermal matrix (ADM). However, based on the findings of literature and systematic reviews, it can be cautiously said that synthetic meshes cause fewer complications with comparable aesthetic results and low cost. In our study, we propose using polytetrafluoroethylene (PTFE) mesh in implant-based breast reconstruction. This material has previously proven itself in cardiovascular, maxillofacial and neurosurgery, hernioplasty and as a suture material. Allogeneic dura mater, which has demonstrated comparable results in breast reconstruction with the literature, will be used as a comparison. The purpose of this study is to evaluate the efficacy and safety of a porous, non-biodegradable, synthetic polytetrafluoroethylene mesh for implant-based breast reconstruction in patients diagnosed with breast cancer. An allogeneic dura mater technique will be used as a control. Patients eligible for this study are classified according to the National Comprehensive Cancer Network (NCCN) guidelines as having stage 0-2 breast cancer. The primary questions this study aims to answer are: * What are the rates of major and minor complications associated with these techniques. Major complications will be defined as complications leading to reoperation. * How effective are PTFE mesh and dura in maintaining the inframammary fold and implant projection after breast reconstruction? * What is the patient satisfaction rate with the surgical results? Patients will be randomly assigned to the study but will know which technique will be used in their particular case. Patients included in this study will undergo subcutaneous mastectomy or skin-sparing mastectomy using standard techniques with simultaneous implantation using PTFE mesh or allogeneic dura mater graft. In our opinion, the mesh and graft will stabilize the projections of the inframammary fold and breast implant. After the surgery, all minor and major complications will be recorded for 6 months. For this, both physical examination and radiological diagnostic methods will be used, including breast ultrasound and MRI with contrast. Revision surgeries will be performed if necessary. Projections of the inframammary fold and breast implant will also be measured in order to determine the effectiveness of the compared techniques. Patients will be asked to complete the BREAST-Q Version 2.0© Reconstruction Module questionnaire to determine satisfaction with the surgical outcome. The results of the study will help the professional community to determine the most effective method of Implant-based Breast reconstruction and will be published in peer-reviewed scientific journals.
NCT06106165
The goal of this non-randomised trial is to test how a workshop that includes religiously-tailored messages can help increase the uptake of breast, colorectal and cervical cancer screening among Muslim women in North East England and Scotland. The results of this trial will inform the development of a full-scale randomised-controlled trial. Participants in this study will be asked to take part in a two-hour workshop, deliver either online or in-person.

NCT01905046
This randomized phase III trial studies metformin hydrochloride to see how well it works compared to placebo in preventing breast cancer in patients with atypical hyperplasia or in situ breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may prevent breast cancer.
NCT06073106
The aging population and its accompanying burden from non-communicable chronic diseases predicts an increasing impact imposed by frailty on healthcare systems. This is due to a lack of normative data for older adults and reliable risk stratification methods to develop effective approaches to the prevention of frailty. In this study, the investigators plan to form a common dataset for phenotype identification, risk stratification of frailty and its targeted treatment plans in the at-risk and mildly frail population.
NCT05914792
This prospective study recruits patients with ER+/HER2-, non-metastatic breast cancer who omit upfront surgery in favor of primary endocrine therapy for sample collection and prospective circulating tumor DNA (ctDNA) measurement to guide disease surveillance.
NCT03962595
Patient satisfaction is the primary means of assessing the effectiveness of primary health care delivery. It helps in improving the quality of care by identifying and help resolving the potential problem areas. It assesses the effectiveness of the care provided and document the quality to accrediting organisations.In our institute, we have developed a patient satisfaction survey (PSS) questionnaire and have conducted a pilot study (Institutional review board approved) with fifty English speaking breast cancer patients receiving active cancer directed treatment in outpatient clinic, to evaluate the level of patient satisfaction in them. Therefore, we are now conducting a linguistic validation study using Hindi and Marathi PSS questionnaire to assess the overall level of patient satisfaction in a larger cohort of patients with diverse linguistic and economic background attending both general and private Outpatient Clinic. The aim of the study is to evaluate the overall level of patient satisfaction and their satisfaction at various encounters in the multi-disciplinary Breast Clinic which can be helpful to improve various aspects of patient care delivery. Methods: All patients who have already sort primary consultation in surgical, medical and radiation oncology outpatient clinics for their treatment plan and have had their last consultation within the last one month will be screened for the study. The Patient Satisfaction Survey (PSS) questionnaire (in preferred language) will be administered independently by a clinical research student who is not directly involved in patient care. The PSS will be anonymous. It will be administered to patients in the out-patient clinics waiting area. Patients will be asked to complete 3 surveys: one each for surgical, medical and radiation oncology professionals. It will take approximately 12 months to enroll the required number of patients. Sample size: Previous studies conducted in India and the pilot study conducted at Tata Memorial Hospital (TMH) with the PSS questionnaire have shown that approximately 70% of the patients are satisfied with the health care services. Assuming that the proportion of patients satisfied with the health services, when assessed by Hindi and Marathi PSS questionnaire will be ± 5% of 70%, i.e. between 65% to 75%, a sample size of 340 will be needed to produces a two-sided 95% confidence interval, which is determined by using Confidence Intervals Formula- Clopper-Pearson method. Potential Impact of the Study 1. Knowledge of patient satisfaction in breast cancer patients belonging to diverse linguistic and socio-economic background will help in improving the quality of life of patients using appropriate resources and measures relevant to Indian context. 2. Awareness of patient dissatisfaction will help improve doctor patient relationship. 3. Awareness of patient dissatisfaction will help to identify problem areas and improve the care delivery.
