Active clinical trials for "Breast Neoplasms"

The goal of this systematic review is to assess the effectiveness of neoadjuvant chemotherapy and Trastuzumab in achieving pathological complete response (pCR) in patients with HER2-positive breast cancer. The main questions it aims to answer are: What is the overall rate of pathological complete response (pCR) in HER2-positive breast cancer patients treated with neoadjuvant chemotherapy and Trastuzumab? Are there any variations in the definition of pCR among the included trials? Participants in the selected clinical trials were HER2-positive breast cancer patients with non-metastatic operable, locally advanced, or inflammatory breast cancer. The main tasks participants were asked to do and the treatments they received are as follows: Undergo neoadjuvant chemotherapy: Participants received chemotherapy treatment before their primary surgery. Receive Trastuzumab: Participants were administered Trastuzumab, a targeted therapy for HER2-positive breast cancer. Researchers would compare the group of participants receiving neoadjuvant chemotherapy and Trastuzumab to other groups, if present, to see if there are differences in the rates of pathological complete response (pCR) or other effects.

The purpose of this study is to test the study method and procedure for individualized piano instruction (IPI) and its impact on chemotherapy related cognitive impairment (CRCI) symptoms. There have been studies that show the benefits of leaning to play the piano keyboard on cognitive skills in children and elderly populations. The information collected from the program will be used to examine the feasibility of implementing this program permanently

The objective is to retrospectively describe and assess clinical and demographical characteristics, treatment patterns in a real-world (RW) setting of patients with HR+/HER2- (hormone receptor positive/human epidermal growth factor receptor 2 negative) locally advanced or metastatic breast cancer receiving palbociclib in combination treatment

The ATLANT study is prospective, multicentre, non-interventional, observational study. Patients with HR+/HER2-negative metastatic breast cancer received abemaciclib as monotherapy or in combination with endocrine therapy.

To evaluate the effectiveness of Contrast-enhanced digital mammography (CEDM) in detecting breast cancer in women at higher risk.

This study is aimed to investigate whether mobile app-based human coaching program for 6 months is effective for reducing BMI in breast cancer survivors with overweight and obesity.

The purpose of this study is to monitor the change in cancer size in women with breast cancer on anti-hormone treatment using different types of assessment including ultrasound scan (US), shearwave elastography (SWE) and magnetic resonance imaging (MRI), and assess how this corresponds to the changes in the cancer biology.

Early detection and treatment of onset or worsening of breast cancer-related lymphedema (BCRL) can potentially prevent or postpone the condition to progress into a chronic progressive condition or eliminate the risk of infections in the arm (cellulitis). Self-surveillance for BCRL by routinely measuring own arm circumference could potentially enable early detection of onset or worsening of lymphedema. The aim is to determine whether women who have received surgery for breast cancer, can perform self-measures of arm circumference in a reliable and valid manner using written and video supported instructions without in-person teaching by a physiotherapist.

Although randomized controlled trials (RCTs) provide evidence of efficacy, generalization of these results to patients in the real-world setting is challenging, given RCTs are conducted in highly selected patient populations. An understanding of the effectiveness of approved cancer therapies in routine clinical practice is essential in order to optimize the management of these patients and to identify treatment and monitoring gaps. This is the first Canadian study to describe real-world treatment patterns/sequencing, effectiveness and monitoring for men and pre/postmenopausal HR+ HER2- advanced breast cancer patients. This registry incorporates an observational prospective cohort design and will enroll 500 men and pre/postmenopausal HR+ HER2- advanced breast cancer women that have been exposed to endocrine therapy (ET) or ET in combination with targeted therapy (TT) including patients receiving CDK4/6 inhibitor therapy combinations..

Patients with large primary operable breast cancers are offered chemotherapy prior to surgery to shrink the tumour and enable breast conserving surgery. Conventional assessment of response to chemotherapy relies on a change in tumour size which does not always correlate with the change in amount of viable tumour. Newer techniques such as functional MRI, microbubble and optoacoustic ultrasound offer the potential to detect responses to chemotherapy by evaluating functional changes in tumour vascularity and oxygenation. Neither modality utilises ionising radiation. Although MRI is widely used for detecting breast cancer, its ability in assessing functional responses to chemotherapy prior to surgery has not been fully exploited. Dynamic contrast enhanced (DCE) MRI has a sensitivity around 90% and provides quantitative measurements of blood volume and flow. Other functional techniques detect variation in tissue oxygenation: this is called the blood oxygen level-dependent (BOLD) mechanism. The BOLD technique uses a special magnetic resonance (MR) sequence called T2* to measure the weakly magnetic effect of deoxygenated haemoglobin. The investigators wish to develop and validate T2* measurements which relate to oxygenation of a tumour. The investigators also want to validate other MR sequences including diffusion weighted (DW) MRI, which quantifies microcirculation of blood in the capillary network and the diffusion of water within tissues. Microbubble ultrasound is an established technique that utilises an intravenous contrast agent comprising tiny microbubbles of gas that can increase the reflectivity of blood and enhance spectral and colour Doppler signals obtained from routine ultrasound imaging. Optoacoustic imaging is new technique where the output signal depends on the oxygenation of the tissues under study. It utilises a light signal input and measures ultrasound signal output. The investigators want to correlate our imaging findings with histopathology after surgical resection of the tumour.
