A Randomized Controlled Comparative Study of Ultrasound-guided Paravertebral Blocks as Part of a...

Breast Diseases

General anesthesia and morphine based pain medicine analgesia has been the mainstay of practice in breast cancer surgery at Women's College Hospital. There is evidence to suggest that patients have a better recovery, with less pain and nausea and vomiting when nerve blocks or freezing of nerves are given in addition to a general anesthetic. Specifically for breast cancer surgery, evidence has suggested that the use of paravertebral blocks provide patients with a better quality of recovery after surgery. The aim of this study is to examine whether patients who receive the nerve blocks using an ultrasound machine in addition to general anesthesia have a better quality of recovery than patients who receive a general anesthetic alone. The hypothesis is that patients receiving ultrasound-guided paravertebral blocks (PVB) with propofol-based general anesthesia (GA) will have a better quality of recovery than patients receiving general anesthesia-opioid-analgesia. Quality of recovery will be assessed using a modification of the QoR-27, a validated instrument to assess postoperative recovery in an ambulatory surgical population.

The Assessment of Molecular Breast Imaging (MBI) in Distinguishing Benign From Malignant Breast...

Breast Abnormalities

The primary hypothesis of this project is that using molecular breast imaging (MBI) in evaluating women with equivocal mammographic or sonographic findings will demonstrate high specificity in distinguishing benign from malignant breast disease and, as a result, decrease the number of biopsies.

Vacuum-Assisted Evacuation (VAE) Of Symptomatic and/or Voluminous Breast Haematomas Following Surgeries...

Breast HaematomaBreast Cancer1 more

Among postoperative complications in breast surgery, hematoma is the most common occurrence. While mostly self-limited, in some cases surgical revision is mandatory when hematoma occurs. Among percutaneous procedures, preliminary studies demonstrated the efficacy of vacuum-assisted breast biopsy(VAB) in evacuating breast hematomas. The aim of the present study is to investigate the efficacy of VAB system in evacuating hematoma, symptoms resolution, and avoidance of surgery. From January 2016 to January 2020 ≥25 mm symptomatic breast hematoma after breast conserving surgery(BCS) and percutaneous procedures were retrospectively enrolled from a perspective maintained database. Preoperative demographic and clinical data were collected. Hematoma maximum diameter, Estimated hematoma volume, total procedure time, and visual analog scale (VAS) score prior ultrasound(US) Vacuum-Assisted Evacuation (VAEv) were recorded. At one week VAS score, residual hematoma volume, and complications were recorded. Study outcomes were defined as clearance of ≥70% postoperative hematoma, symptoms resolution (assessed as patient report visual analog scale (VAS≤3)), and avoidance of surgery during follow-up.

China CellSearch Study

Metastatic Breast CancerBenign Breast Disease

The study is designed to confirm the current indication (below) of the CellSearch® Circulating Tumor Cell Kit in metastatic breast cancer (MBC) patients for use of the kit in China. The CellSearch® Circulating Tumor Cell Kit is intended for the enumeration of circulating tumor cells (CTC) of epithelial origin (CD45-, EpCAM+, and cytokeratins 8, 18+, and/or 19+) in whole blood. The presence of CTC in the peripheral blood, as detected by the CellSearch® Circulating Tumor Cell Kit, is associated with decreased progression free survival and decreased overall survival in patients treated for metastatic breast cancer. This test is to be used as an aid in the monitoring of patients with metastatic breast cancer. Serial testing for CTC should be used in conjunction with other clinical methods for monitoring metastatic breast cancer. Evaluation of CTC at any time during the course of disease allows assessment of patient prognosis and is predictive of progression free survival and overall survival.

Nuclear Morphology of Breast Cells in Ductal Lavage

Benign Breast Disease

Breast nipple aspirate fluids (NAF) are useful for non-invasive monitoring of the breast. NAF has been shown to exhibit large inter-individual differences in lipid peroxidation. Unfortunately, the yield of epithelial cells in NAF is low. More recently, breast ductal lavage has been approved for clinical use. Nuclear morphologic features of breast biopsies have been shown previously to have prognostic value for breast cancer risk. In women without cancer, there may be subtle changes in the breast epithelial cells that can only be defined with computer-assisted measurements. The subjects selected for this study will be 98 women with biopsy-confirmed proliferative breast disease. These women are at slightly increased breast cancer risk, and exhibit higher mean levels of cholesterol and cholesterol oxides in NAF than women with non-proliferative histology in the breast. Levels of 8-isoprostane, cholesterol, fatty acids, fat-soluble micronutrients and 2,6-cyclolycopene-4,5-diol will be quantified in breast NAF that is obtained before breast lavage. These measures were chosen based on their potential relationship to dietary intakes and to oxidative stress, which is relevant to the application of these methods to dietary prevention studies.The investigators will characterize the morphology of breast epithelial cells from lavage using quantitative image cytometry to capture nuclear and cellular area, diameter, roundness, perimeter, and nuclear:cytoplasmic area ratio. Correlations will be evaluated between the measured morphologic features and each analyte in the NAF. The impact of various clinical, demographic and dietary factors on cellular morphology will also be explored. This study will help establish the feasibility of using these measures as endpoints in dietary intervention studies and will generate hypotheses that should be tested in larger studies. Such measures also should be applicable to molecular epidemiological investigations that seek to examine the impact of certain gene polymorphisms and environmental exposures on biomarkers of cancer risk.
