NCT ID: NCT05650086 Suspended - Breast Cancer Clinical Trials

Novel Thermal Imaging Technique for Breast Screening

Start date: November 15, 2022
Study type: Observational

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.

NCT ID: NCT05506800 Suspended - Breast Cancer Clinical Trials

Guangzhou Women's Health Cohort Study (GWHCS)

Start date: March 3, 2016
Study type: Observational

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.

NCT ID: NCT04955808 Suspended - Multiple Myeloma Clinical Trials

Biospecimen Collection in Identifying Genetic Changes in Patients With Breast, Prostate, Colorectal, Liver, or Kidney Cancer or Multiple Myeloma Undergoing Surgery

Start date: February 7, 2017
Study type: Observational

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.

NCT ID: NCT04803084 Suspended - Breast Cancer Clinical Trials

Multiparametric MRI as a Non-Invasive Biomarker of the Tumor Microenviroment

Start date: August 9, 2021
Study type: Observational

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.

NCT ID: NCT04714983 Suspended - Breast Cancer Clinical Trials

DNX-2440 for Resectable Colorectal Liver Metastasis

Start date: February 15, 2021
Phase: Phase 1
Study type: Interventional

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.

NCT ID: NCT04683120 Suspended - Breast Cancer Clinical Trials

Real-time Diagnosis and Visualization of Tumor Margins in Excised Breast Specimens Using Zenith FLIM Diagnostics

Start date: December 15, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04474652 Suspended - Breast Cancer Clinical Trials

Guide for Prioritisation of Patients for Referral to Breast Clinics

Start date: February 12, 2020
Study type: Observational

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.

NCT ID: NCT04397185 Suspended - Clinical trials for Breast Cancer Female

Breast Cancer Locator Guided vs. Wire Localized Partial Mastectomy for Breast Cancer

Start date: December 23, 2020
Phase: N/A
Study type: Interventional

This prospective, multicenter, 1:1 randomized, controlled trial is designed to evaluate the safety and effectiveness of the Breast Cancer Locator (BCL) in subjects with non-palpable invasive breast cancer or ductal carcinoma in situ (DCIS). Subjects will be randomized to breast conserving surgery (BCS) utilizing either the BCL or wire localization (WL) to guide surgery.

NCT ID: NCT04339517 Suspended - Breast Cancer Clinical Trials

Postoperative Identification of Tumor Cells at the Lumpectomy Site of Patients With Early Breast Cancer

Start date: August 17, 2021
Phase: N/A
Study type: Interventional

For early breast cancer, local surgery followed by breast radiation is a standard local treatment. It has been found that the original primary tumor site, the lumpectomy site, is the commonest location of local relapse. The researchers think that such relapse occurs because of persistent tumor cells (PTCs) at the lumpectomy site even when conventional pathology reports indicate complete resection with clear margins. The researchers propose to analyze the lumpectomy fluid (seroma) of patients who are one to six weeks post-surgery for the presence or absence of tumor cells using new technology. Results of this study may help identify women who may have increased local relapse risk beyond that suggested by conventional pathology and clinical features; it may also help identify women at very low risk of local relapse who could avoid any additional treatment after local surgery.

NCT ID: NCT04292847 Suspended - Breast Cancer Clinical Trials

LCCC1931:Post-treatment Intervention in Women With Breast Cancer (70y/o+)

Start date: March 12, 2020
Phase: N/A
Study type: Interventional

This study recruits woman over the age of 70 who have completed primary treatment for early breast cancer in the last 2 months. A survey called the geriatric assessment will be used to identify symptoms and issues participants experience.This information will be given to the patient's medical oncology team, and used to make referrals to specialists. This study is designed to determine if these assessments and timely interventions can be completed during clinic visits, and determine if these participants comply with recommendations.
