Filter by:This trial is to study a new breast imaging tool called Thermalytix™. ThermalytixTM is a new radiation-free, automated breast cancer screening technique that uses Artificial Intelligence (AI) over thermal images. Thermal images are heat signatures in our body. This new technique will capture heat signatures in the breast and analyze those images with AI software. This study will evaluate the performance of ThermalytixTM breast imaging against standard imaging modalities, such as mammography and ultrasound.
The Guangzhou Women's Health Cohort Study aims to explore the health trajectory and factors contributing to the health of women aged 35-64 in Guangzhou. Based on multiple population health registration data platforms, data of the cohort will provide information about the health of women across the lifespan, facilitating the decision-making process by local government . The cohort is progressing steadily, and the goal is to build a large women cohort covering 11 administrative districts of Guangzhou with a scale of 1 million by 2030.
This phase II trial tests whether [18F]FluorThanatrace by positron emission tomography (PET)/computed tomography (CT) can improve imaging techniques in patients with breast cancer undergoing a standard of care biopsy or surgery. [18F]FluorThanatrace is a new radioactive tracer, which is a type of imaging agent that is labeled with a radioactive tag and injected into the body to help with imaging scans. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, [18F]FluorThanatrace. Because some cancers take up [18F]FluorThanatrace it can be seen with PET. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. [18F]FluorThanatrace by PET/CT may help detect the activity of a certain enzyme in the body that may be related to cancer growth in patients with breast cancer.
Patients with breast cancer are commonly treated with taxane chemotherapy. Some very common side effects of taxanes, such as anemia and peripheral neuropathy, are often as not well addressed during treatment, resulting in dose reductions, dose delays and early discontinuation (collectively called relative dose intensity) of these chemotherapy agents in 15-80 % of patients on these drugs. This reduction in relative dose intensity (RDI) results in worse clinical outcomes such as progression free and overall survival. Pre-clinical studies in mouse models subjected to standardized chemotherapy regimens containing paclitaxel or oxaliplatin have shown that the nutritional supplement Epidiferphane reduces both neuropathy and anemia. This study will investigate whether the use of Epidiferphane in patients with breast cancer receiving taxane chemotherapy results in an attenuation of the side effects experienced, as well as an improvement in tumor response rate. The safety and maximum tolerated dose of Epidiferphane in this patient population will also be determined in this study.
This research trial studies how well biospecimen collection works in identifying genetic changes in patients with breast, prostate, colorectal, liver, or kidney cancer or multiple myeloma undergoing surgery. Studying samples collected during surgery may add to the understanding of cancer by looking for the genetic changes that cause early cancer onset in people of certain racial and ethnic groups.
This study is looking at how an imaging test could help doctors understand if a patient with early breast cancer will respond to drugs that use the patient's immune system to fight cancer.
The purpose of this study is to test an experimental oncolytic adenovirus called DNX-2440 in patients with resectable multifocal (≥ 2 lesions) liver metastasis, who are scheduled to have curative-intent liver resection surgery. Up to 18 patients will receive two sequential intra-tumoral injections of DNX-2440 into a metastatic liver tumor prior to surgery for liver resection, to evaluate safety and biological endpoints across 3 dose levels (dose escalation). Upon conclusion of the dose-escalation phase, the selected safe and biologically appropriate dose will be administered using the same schema for an additional 12 patients with colorectal cancer liver metastasis (expansion cohort) using established biologic endpoints.
Our investigational team has developed a technology to visualize the operative margins in 'real time,' in other words during the operation while the patient is still on the table. While different surgeons use different operative techniques, our technique involves removing the main lumpectomy specimen, marking two of its borders with suture to orient the specimen for correct pathologic evaluation. The FLIM (Fluorescent Lifetime Imaging Microscopy) technique can differentiate between cancerous and noncancerous specimens using a complex algorithm that essentially utilizes a definitive delta between the metabolic activities of diseased and non-diseased tissue. The research coordinator along with the surgeon will be able to insert the lumpectomy specimen followed by the 6 shaved margins (one by one) in a matter of minutes once the specimens have been resected. To be clear, the FLIM analysis will be taking place in- vitro. The device is invitro test and would be tested against the gold standard the pathologist biopsy. FLIM analysis by the surgeon will not take more than several minutes, therefore not adding any significant time for patient to be under anesthesia. All specimens will be removed from the patient's body prior to their evaluation by the FLIM technique. Our team will not be making decisions based on FLIM analysis during this early phase of study. In other words, even if FLIM suggests a positive margin still exists in the body, our team will not act on these results by resecting additional tissue at this stage. FLIM margin results will be compared directly with pathology results for accuracy of the findings.
Women with personal history of breast cancer (PHBC) are at risk of developing second breast cancers in the conserved and contralateral breast. Because early detection of second breast cancers at the asymptomatic phase can improve relative survival by 17-28%, guidelines recommend annual mammography screening in women with PHBC. However, lower sensitivity and higher interval cancer rates are observed in women with a PHBC compared with women without, especially in women 50 years or younger and those with dense breasts. In a multicenter comparison study of 754 women, MRI screening detected 3.8 additional cancers and ultrasonography detected 2.4 additional cancers, and increased sensitivity over mammography alone. However, the use of breast MRI is limited not only by high costs and long examination time but also by high false-positive findings. In addition, the use of intravenous gadolinium-based contrast agent is contraindicated in women with renal impairment or contrast material allergy contrast. Supplemental ultrasonography in patients with PHBC reports lower sensitivity with high interval cancer rate. Thus, there is a need to develop a more safe, accurate, and cost-effective supplemental imaging modality for screening in women with PHBC. Diffusion-weighted (DW) MRI is an unenhanced fast, functional modality that measures the movement of water molecules to create tissue contrast. Breast malignancies exhibit hindered diffusion and appear hyperintense on DW MRI with low apparent diffusion coefficient (ADC) compared to normal surrounding tissue. Multiple studies have shown that the use of DW MRI can significantly reduce the false positives and unnecessary benign biopsy of breast MRI. Several studies have shown that DW MRI has a potential to detect mammography occult breast cancers with less false positives compared to ultrasonography. These observations have led to the consideration of utilizing DW MRI to screen women with PHBC. In Diffusion-weighted MRI for Breast Cancer Screening (DIMRISC-2) study, we hypothesized that the screening performance of high-resolution DW MRI at 3.0 T should be superior to mammography alone or combined mammography and ultrasonography in women with PHBC. In our institution, alternating conventional imaging and DW MRI screening is offered for patients who have undergone breast surgery and at increased risk of an interval second breast cancer.
GPs in primary care in England currently refer over 2.17 million patients per year with vague symptoms to the urgent cancer referral pathway. While this catches over 150,000 cancer cases each year, 93% of the referred patients do not have cancer. For breast cancer, GPs refer 343,000 cases per year. Each of these patients are referred to a one stop clinic for diagnosis. The Leeds teaching Hospitals' Trusts' Breast Unit, receives 10,000 per year, with only 5% of patients actually being diagnosed with cancer. The breast cancer pathway involves a triple assessment process, which includes a clinical examination, imaging (mammogram or ultrasound) and possibly a biopsy test. It is a particularly expensive process as it is an imagingintense pathway; this places considerable strain on NHS diagnostic facilities. Small changes will not be enough to solve this problem - a new approach is needed. The purpose of this study is to see if we can develop a blood test that can support doctors in identifying patients for whom the likelihood of having breast cancer is extremely low. This would avoid unnecessary referral for those patients to the one stop clinic. Patients with higher chances of suspected breast cancer would be referred to the one stop clinic in the usual way. Key to the idea of safely "ruling-out" patients is that the test must not miss patients who do have cancer. By measuring a broad range of indicators (markers) in blood, the test will provide a more accurate picture of the underlying biology. The test is also being developed within the NHS, so that it can be adopted quickly into NHS computer systems and laboratories to maximise patient benefit, whilst being held to the NHS's high standards for clinical evidence and value.
