By: M. Alexander Otto, PA, MMSc From: medscape.com MRI can identify patients with HER2-positive breast cancer who don’t need a full course of neoadjuvant chemotherapy, letting them avoid the toxicity of unnecessary treatment while preserving 3-year event-free survival, new trial findings suggest. The study, published in The Lancet Oncology, found that patients had “excellent” outcomes even if they received only …
MRI predicts treatment response for triple-negative breast cancer
By: Amerigo Allegretto From: auntminnie.com Post-treatment MRI can accurately predict treatment response for early triple-negative breast cancer, according to research published July 1 in Radiology. A team led by Toulsie Ramtohul, MD, from the Curie Institute in Paris, France, found that their logistic regression model, which used radiologic complete response, nodal involvement, and Ki-67 indexing, achieved high predictive value for complete …
Brain MRI tracks risk of stage IV breast cancer metastases
By: Kate Madden Yee From: auntminnie.com Brain MRI shows promise for surveilling women at risk for asymptomatic stage IV breast cancer metastases by tracking molecular subtypes of the disease, researchers have reported. “[We found that the] highest frequency of brain metastases at baseline was in triple-negative and HER2-positive [human epidermal growth factor receptor 2-positive] breast cancer,” wrote a team led …
New AI tool to detect possible metastatic breast cancer
From: utsouthwestern.edu Researchers at UT Southwestern Medical Center have developed a novel artificial intelligence (AI) model to improve the detection of breast cancer metastasis, which could reduce the need for needle or surgical biopsies. The noninvasive model uses standard magnetic resonance imaging (MRI), paired with machine learning AI, to detect axillary metastasis – the presence of cancer cells in the …
Prediction of Lymphovascular invasion status in breast cancer based on magnetic resonance imaging radiomics features
From: sciencedirect.com Abstract Objective This study intended to investigate the feasibility and effectiveness of using clinical magnetic resonance imaging (MRI) radiomics features to predict lymphovascular invasion (LVI) status in breast cancer (BC) patients. Methods A total of 182 BCE patients were retrospectively collected and randomly divided into a training set (n = 127) and a validation set (n = 55) in a 7:3 ratio. Based …
Contrast-enhanced mammography for breast cancer staging offers significant cost savings
By: Hannah Murphy From: healthimaging Contrast-enhanced spectral mammography (CESM) is a cost-effective alternative to MRI for patients with breast cancer and could save facilities potentially tens of thousands of dollars every year. Experts from the University of Dundee and King’s College London, both in the United Kingdom, recently compared the costs of the two modalities for loco-regional breast cancer staging. They …
Preoperative breast MRI linked to reduced recurrence risk
By: Amerigo Allegretto From: auntminnie.com Preoperative MRI is tied to reduced risk of breast cancer recurrence in patients aged 50 years or younger with cancer diagnosis and for hormone receptor-negative cancers, research presented December 1 at the RSNA annual meeting found. In her talk, Dr. Heera Yoen from Seoul National University Hospital in South Korea presented her team’s findings, which suggest …
MRI Alone Beneficial for Surveillance After Breast-Conserving Treatment
By: Katie Robinson From: diagnosticimaging.com Following breast cancer treatment, women who have access to breast MRI may safely forgo additional mammographic or digital breast tomosynthesis follow-up. Study results presented at the Radiological Society of North America (RSNA) 2021 Annual Meeting suggest that magnetic resonance imaging (MRI) alone is a successful method for the follow-up in women who undergo breast-conserving treatment and …
Breast MRI Shows IUDs Have Systemic Effects
Source: Radiological Society of North America (RSNA) From: prnewswire.com Intrauterine contraceptive devices (IUDs) appear to have systemic effects on the body like those of hormone replacement therapy, according to a breast MRI study being presented next week at the annual meeting of the Radiological Society of North America (RSNA). “It has been claimed that IUDs have a purely local effect …
Providers are requesting fewer preoperative MRIs for breast cancer patients
By: Hannah Murphy From: healthimaging.com Providers are requesting fewer preoperative MRI exams for breast cancer patients, but a new analysis suggests more can be done to align with evidence-based guidelines. In 2016 the American Society of Breast Surgeons published “Choosing Wisely,” which opposed the preoperative use of MRI in breast cancer patients. The document cited multiple concerns with the practice—increased need for …
