A comparative analysis of axillary nodal burden in ultrasound/biopsy positive axilla vs ultrasound negative sentinel lymph node biopsy positive axilla.

A comparative analysis of axillary nodal burden in ultrasound/biopsy positive axilla vs ultrasound negative sentinel lymph node biopsy positive axilla. Breast Dis. 2019 Mar 22;: Authors: Tandon M, Ball W, Kirby R, Soumian S, Narayanan S Abstract BACKGROUND: Axillary Ultrasound (AUS) is now performed as a protocol in every newly diagnosed breast cancer in most European countries. It is an inexpensive and sensitive tool in hands of a trained operator. All AUS negative patients undergo Sentinel Lymph Node Biopsy (SLNB), while AUS positive patients bypass SLNB and undergo axillary nodal clearance (ANC) as a standard protocol. We wish to analyse these two groups to see if ANC can be foregone in these patients. AIMS AND OBJECTIVES: To compare and analyse the axillary disease burden in early breast cancer patients, with positive axilla, detected by AUS+ Biopsy versus those patients with normal axillary ultrasound or negative axillary biopsy that underwent ANC due to positive SLNB. MATERIAL AND METHODS: A retrospective review of all patients who underwent axillary lymph node clearance following histologically confirmed positive ultrasound (US) axilla (year 2009-2014) was performed and was compared with data collected for patients with USG negative but SLNB (OSNA- One Step Nucleic Acid Amplification) positive axilla. RESULTS: Axillary clearances performed for positive US axilla yielded significantly more positive lymph nodes than SLNB/OSNA positive axi...

Authors: Laura B, Alice C, Silvia G, Cristiana B, Giuseppe DT, Antonio A, Giuseppina OM Abstract Mastectomy and breast prosthetic reconstruction is the most common surgical treatment for women diagnosed with breast cancer. In the last few years, breast prosthetic augmentation in acellular dermal matrix (ADM) has been introduced. The aim of this study is to present our single-center experience in evaluating the outcome of patients who underwent breast reconstruction in ADM, using ultrasound (US) examination. US follow-up allows evaluating both normal postoperative findings and changes and potential local complicatio...

CONCLUSIONS: We established a novel One-step model which improves location accuracy by generating more precise bounding box via Seg-net and removing false targets by another object detection network (Cls-net). On the other hand, a real-time detection of tumor is achieved by sharing the common Base-net. The experimental results showed that the new model performed well on various irregular and blurred ultrasound images. As a result, this study demonstrated feasibility of applying deep learning scheme to detect breast lesions depicting on US image. PMID: 31306148 [PubMed - as supplied by publisher]

ConclusionsReconsidering the use of ultrasound in patients with early breast cancer and non-palpable axillae reveals that sentinel node biopsy itself may represent surgical over-treatment in patients with a negative axillary ultrasound. The implications of this on the future of surgical management of the axilla are discussed.

AbstractPurposeTo develop a multiparametric [18F]FDG positron emission tomography/magnetic resonance imaging (PET/MRI) model for breast cancer diagnosis incorporating imaging biomarkers of breast tumors and contralateral healthy breast tissue.MethodsIn this prospective study and retrospective data analysis, 141 patients (mean 57  years) with an imaging abnormality detected on mammography and/or ultrasound (BI-RADS 4/5) underwent combined multiparametric [18F]FDG PET/MRI with PET/computed tomography and multiparametric MRI of the breast at 3  T. Images were evaluated and the following were recorded: for the tumor,...

(University of Southern California) Breast ultrasound elastography is an emerging imaging technique used by doctors to help diagnose breast cancer by evaluating a lesion's stiffness in a non-invasive way. USC researchers identified the critical role machine learning can play in making this technique more efficient and accurate in diagnosis.

Abstract Breast cancer is the most common cancer among females worldwide and large volumes of breast images are produced and interpreted annually. As long as radiologists interpret these images, the diagnostic accuracy will be limited by human factors and both false-positive and false-negative errors might occur. By understanding visual search in breast images, we may be able to identify causes of diagnostic errors, find ways to reduce them, and also provide a better education to radiology residents. Many visual search studies in breast radiology have been devoted to mammography. These studies showed that 70% of m...

Since it was first described, the clinicians wonder if this new simple technique can replace paravertebral block (PVB). We aimed to compare the postoperative analgesic effect of ESP block and PVB with a control group in breast surgeries. DESIGN: Randomized controlled trial. SETTING: Operating room. PATIENTS: Seventy-five ASA I-II patients aged 25-65, who were scheduled to go under elective unilateral breast surgery for breast cancer...

Contrast-enhanced ultrasound (CEUS) utilising microbubbles shows great potential for visualising lymphatic vessels and identifying sentinel lymph nodes (SLNs) which are valuable for axillary staging in breast cancer patients. However, current CEUS imaging techniques have limitations that affect the accurate visualisation and tracking of lymphatic vessels and SLN. (i) Tissue artefacts and bubble disruption can reduce the image contrast. (ii) Limited spatial and temporal resolution diminishes the amount of information that can be captured by CEUS.
