Filter by:People treated for breast cancer often live with an ongoing fear that the cancer will recur. This fear may develop and impact on their mental health and quality of life. The Mini-AFTERc study is a pilot trial of a brief cognitive behavioural communication intervention, designed to reduce fear of cancer recurrence (FCR) in breast cancer patients. This pilot trial aims to determine the acceptability and practicality of introducing the Mini-AFTERc intervention into everyday practice, and inform the development of a full randomised controlled trial.
This study will look at effects the combination of palbociclib and dose-dense neoadjuvant chemotherapy may have on triple negative breast cancer tumours which have not yet been treated.
The purpose of the study is to investigate the impacts of radiation and the timing of radiation on autologous and prosthetic-based breast reconstruction in Chinese post-mastectomy breast cancer patients. The study aims to optimize the timing for autologous/prosthetic breast reconstruction which delivers the best aesthetic results while maintains low complication rate and best integrates into the comprehensive breast cancer treatment. The study is open to all female breast cancer patients undergoing breast reconstruction in the department of breast reconstruction in Tianjin medical university cancer institute and hospital.
The aim of this study is to answer the question: can the IGAR-Breast safely and effectively perform teleoperative breast biopsies? This is a prospective, pilot trial. 5-10 participants will be selected by the radiologist and the success of biopsy analyzed. In addition the number of adverse events, device events and procedural deviations will be assessed to determine safety and efficacy.
This study is a prospective, open-label study to examine the performance of the LightPath® Imaging System using the PET tracer 68Ga-RM2 in patients scheduled for and/or undergoing wide local excision (WLE) with or without sentinel lymph node biopsy (SLNB) or complete axillary lymph node dissection(cALND) for breast cancer with an ER-positive invasive primary cancer. The study consists of 3 sequential groups: Group 1 (N=20 patients): Torso, i.e. base of skull to thighs, PET/CT imaging and axillary gamma probe measurements (using a collimator) of 68Ga-RM2 to: determine the optimal scan time-window post-injection; to extrapolate the optimal dose for resolution against axillary background signal on gamma probe measurements (first 6 patients); and the value of 68Ga-RM2 PET/CT imaging for breast cancer staging (all 20 patients). Group 2 (N=10 patients): Intraoperative LightPath® imaging with 68Ga-RM2 to familiarise site with procedure and interpretation of intraoperative scans,validate the dose and timings determined from Group 1, and optimise LightPath® Imaging parameters such as acquisition resolution and duration. Group 2 scans will acquire LightPath® images of both intact and incised cancer specimens for post-operative standardised, controlled assessment. Group 2 will use the optimal scan time-window and 68Ga-RM2 activity extrapolated from at least the first 6 patients in Group 1. The dose of 68Ga-RM2 will be determined to optimise the intra-operative imaging and axillary gamma probe measurements. Group 3 (N=50 patients): Intraoperative LightPath® imaging with 68Ga-RM2 to measure agreement between LightPath® images and post-operative histopathology. Group 3 scans will acquire LightPath® images of intact and incised cancer specimens for post-operative standardised, controlled assessment. Group 3 will use the optimal scan time-window and 68Ga-RM2 activity extrapolated from the first 6 patients in Group 1 with the optimised imaging parameters, and dose developed from Group 2. The intraoperative LightPath® Images will be used to inform the surgeons about detectable residual cancer in an attempt to achieve better guided cancer surgery and complete tumour excision with clear WLE resection margins The study site will use the local criteria considered standard of care to guide decisions to act on positive margins. Lightpoint Medical will provide guidance to act on LightPath® Images in the Instructions forUse (IFU). It will be at the Investigator's discretion to choose whether to act based upon the intraoperative LightPath® Images. In Group 3,the resection margin status of the WLE specimen, cavity shavings (if any) and the metastatic status of axillary (sentinel) lymph nodes as measured with the LightPath® Imaging System will be compared with histopathology results. A positive margin on histology will be defined as - Invasive carcinoma: positive: ink on tumour; close: <1mm; negative ≥1mm - Ductal carcinoma in situ (DCIS)or pleomorphic lobular carcinoma in situ (LCIS) (if present): positive: ink on tumour; close: <2mm; negative ≥2mm.
The purpose of this study is to compare the qualitative severity and depth of dissection devices' associated thermal artifact in breast lumpectomy shaved margins between the use of electrocautery and low thermal energy dissection, PhotonBlade. The investigators hypothesize that the use of PhotonBlade would result in a significantly lower qualitative severity and a shorter depth of thermal artifact in breast lumpectomies shaved margins, when compared to electrocautery devices.
Systemic chemotherapy along with radiotherapy has been successfully used to post-operatively manage patients following tumour resection in breast cancer. This was further supported with clinical trials conducted in the 1970s and 1980s which shows significant improvement in progression-free of tumours and overall survival rates in patients who undergo chemotherapy for operable breast cancer.(1)-(2) Neoadjuvant chemotherapy on the other hand, involves the administration of the chemotherapeutic agents some weeks before appropriate breast surgery. This induces reduction in the tumour size and allows for breast conservative surgery instead of mastectomy in some cases. Techniques for tumour localization in neoadjuvant chemotherapy using metallic markers allowing lower excision of breast tissue without compromising margins and breast conservation being feasible in many patients have evolved over time.(3)-(7)-(9) However, there are recent concerns questioning the increase use of neoadjuvant chemotherapy in breast cancer it as it may not be beneficial to patients in the long run.(10)
Breast cancer is the most common malignant tumor in women worldwide,and there exist a large part of patients need to receive neoadjuvant chemotherapy(NAC) before the curative surgery.Circulating tumor DNA(ctDNA) is the circulating free DNA in the blood that originates from cancers,and it can be detected by modern technologies in plasma.In this prospective study,investigators aim to observe the correlation between tumor response to neoadjuvant chemotherapy and ctDNA.
The purpose of the study is to estimate the diagnostic accuracy of preoperative ultrasound-guided axillary lymph node biopsy for staging in patients with newly diagnosed breast cancer, and also to compare between ultrasound-guided fine needle aspiration cytology and core needle biopsy in their ability to detect metastatic disease in the axillary lymph nodes of patients with breast cancer.
Breast cancer remains the most common cancer in women worldwide. Semaphorin4C (SEMA4C) has previously been identified as a highly expressed protein by breast cancer-associated lymphatic endothelial cells (LECs). The objective of this study is to investigate SEMA4C's potential role as an early relapse biomarker in breast cancer.
