Conventional US combined with acoustic radiation force impulse (ARFI) elastography for prediction of triple-negative breast cancer and the risk of lymphatic metastasis. Clin Hemorheol Microcirc. 2017;65(4):335-347 Authors: Pu H, Zhao LX, Yao MH, Xu G, Liu H, Xu HX, Wu R Abstract PURPOSE: To evaluate the combination of conventional ultrasound (US) and acoustic radiation force impulse (ARFI) elastography in predicting triple-negative breast cancer and the likelihood of lymphatic metastasis. MATERIALS AND METHODS: A total of 178 women presenting from May 2013 to September 2015 with pathologically proven triple-negative (n = 60) or hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer (n = 118) were reviewed. Conventional US and ARFI imaging including Virtual touch tissue image (VTI) and Virtual Touch tissue Quantification (VTQ), were performed for each breast nodule. Parameters collected included patient age, lymph node involvement, histological grade, tumor subtype, appearance on conventional US, shear wave velocity (SWV) value, VTI score and the boundary on VTI. The ARFI findings were compared with the pathological findings. RESULTS: Younger age (P

CONCLUSIONS: This model could be a helpful tool for the surgeon to help in predicting which cases have a higher likelihood of achieving a pathologically complete response and therefore selecting those who may benefit from a post-neoadjuvant chemotherapy sentinel lymph node biopsy and avoid unnecessary axillary lymphadenectomy.

ConclusionHeterogeneity in hormone receptor status alters the therapeutic management of patients with synchronous bilateral breast cancer. Both hormone therapy and chemotherapy should be considered in these patients.It is of utmost importance to evaluate the tumor receptor status in cases of synchronous bilateral breast tumour and to assess for change in relation to tumour progression or treatment. Further study in the status change of receptors could open up new treatment modalities.

ConclusionSolely regarding sensitivity of AUS, our study could show significant differences between biological subtypes of breast cancer with lower sensitivity in Luminal patients. While PPV was excellent, standing for a low overtreatment rate using AUS for clinical decision making, sensitivity was poor overall, comparable to the results of other studies.

Conclusion: Microcalcification detected on mammography and certain ultrasound features such as circumscribed or non-circumscribed margins, posterior acoustic features, and vascularity are strongly correlated in predicting the molecular subtypes of breast cancer, and thus may further expand the role of conventional breast imaging.

A 47-year-old premenopausal woman with no known family history of breast cancer and an unremarkable medical history presented to her primary care physician after palpating a mass in her left breast. A mammogram and ultrasound demonstrated a 3.2  × 1.3-cm mass at 3 o'clock, 4 cm from the nipple, in her left breast. A biopsy showed invasive ductal carcinoma, intermediate nuclear grade, with associated high-grade ductal carcinoma in situ (DCIS). Estrogen and progesterone receptors stained positive, HER2 was negative by FISH, and Ki67 was 25%.

DiscussionUse of AUS may help to tailor patient care without leading to overutilization of ALND, as long as neoadjuvant chemotherapy is administered when appropriate.

A 35-year-old woman noticed a mass in her right breast and underwent a diagnostic workup, including a mammogram that revealed a 2.4-cm mass and ultrasound that showed two adjacent masses, as well as enlarged axillary lymph nodes.

Authors: Lv W, Shen Y, Yang H, Yang R, Cai W, Zhang J, Yuan L, Duan Y, Zhang L Abstract Nanobubble (NB), a newly developed nanoscaled ultrasound contrast agent (UCA) for molecular imaging, has been widely researched for these years. Targeting it with functional molecule, nanobubble can adhere selectively to cellular epitopes and receptors outside the vasculature via enhanced permeability and retention (EPR) effect of tumor blood vessel. To enhance the targeting rate of our previous prepared NBs-Affibody for HER2 (+) breast cancer imaging, we introduced a near-infrared fluorescent (NIRF) dye, IR783, in this study to...

Authors: Chiorean AR, Szep MB, Feier DS, Duma M, Chiorean MA, Strilciuc Ș Abstract AIMS: The purpose of this study was to determine the impact of strain elastography (SE) on the Breast Imaging Reporting Data System (BI-RADS) classification depending on invasive lobular carcinoma (ILC) lesion size. MATERIALS AND METHODS: We performed a retrospective analysis on a sample of 152 female subjects examined between January 2010 - January 2017. SE was performed on all patients and ILC was subsequently diagnosed by surgical or ultrasound-guided biopsy. BI-RADS 1, 2, 6 and Tsukuba BGR cases were omitted. BI-RADS scores ...

Abstract PURPOSE: To investigate breast cancers total hemoglobin concentration (THC) characteristics and its association with clinical pathologic findings. MATERIALS AND METHODS: The study was approved by the institutional review board and all patients provided written informed consent. 447 breast cancer patients, totally 455 lesions were included in our study. The size and THC of breast lesions were measured by conventional ultrasound (US) and US-guided Diffuse Optical Tomography (DOT) 1-2 days before surgery. Clinical and pathology information of patients was collected. RESULT: The average THC values...
