Background: Intraoperative margin assessment for breast cancer patients undergoing segmental mastectomy (SM) enables identification of positive margins, with immediate excision of additional tissue to obtain negative margins.

Objective: The aim of this study was to determine the ability of digital breast tomosynthesis (DBT) to detect positive margins compared with an institution's standard extensive processing (SEP).

Methods: SM specimens underwent intraoperative SEP with two-dimensional (2D) imaging of the intact and sliced specimen, with review by a breast radiologist and gross assessment by a breast pathologist. Read More

BACKGROUND The incidence of flat epithelial atypia of the breast has been increasing owing to the increasing use of ultrasonography (US) and US-guided core needle biopsy. However, reports describing the sonographic features of flat epithelial atypia are fewer than those on its mammographic features. CASE REPORT A 47-year-old female had a regular 6 month-interval follow-up US for multiple bilateral breast masses detected on US. Read More

Background: The presence of tumor-infiltrating lymphocytes (TILs) is a prognostic factor for breast cancer. However, because of tumor tissue heterogeneity, an accurate and simple evaluation method is needed. We determined if preoperative characteristic ultrasonography (US) image findings are predictive of lymphocyte-predominant breast cancer (LPBC). Read More

Fibroadenoma, being a very common benign tumor of the breast in young females, does not pose any threat and, thus, can be treated with lumpectomy. Breast cancer arising within a fibroadenoma is a rare phenomenon, but detecting these neoplasms is of utmost importance for complete treatment and follow-up. These lesions are an incidental finding in a lumpectomy specimen done for fibroadenoma breast. Read More

Background: A biopsy of first recurrence or metastatic disease is recommended to re-evaluate oestrogen receptor status in patients with breast cancer and to select appropriate treatment. However, retesting for oestrogen receptor status with rebiopsy is not always feasible, depending on lesion location and the risk associated with biopsy, and in these cases clinicians continue to treat patients according to the oestrogen receptor status of the primary tumour. Consequently suboptimal therapy might be offered to these patients. Read More

Near infrared (NIR) imaging is a rapidly developing technique with promising use as a non-invasive, specific and sensitive diagnostic tool. While the NIR fluorescently labeled glucose analog, glucosamine (cypate-glucosamine), has been used for imaging purposes, the transport pathways and fate of this probe in tissues remain unaddressed. Here, we synthesized and characterized cypate and cypate-glucosamine conjugate (cy-2-glu), and investigated the probable transport pathways of these probes in vitro and in vivo. Read More

Background/aim: The interval between diagnostic imaging and whole-brain radiotherapy (WBRT) had no significant impact on survival in our previous study of WBRT for brain metastases. Since median survival time was only 2 months, a potentially negative impact by delaying treatment could have been missed. Therefore, we performed an additional analysis of patients surviving at least 4 months following irradiation. Read More

Leveraging the unique surface expression of heat shock protein 90 (Hsp90) in breast cancer provides an exciting opportunity to develop rapid diagnostic tests at the point-of-care setting. Hsp90 has previously been shown to have elevated expression levels across all breast cancer receptor subtypes. We have developed a non-destructive strategy using HS-27, a fluorescently-tethered Hsp90 inhibitor, to assay surface Hsp90 expression on intact tissue specimens and validated our approach in clinical samples from breast cancer patients across estrogen receptor positive, Her2-overexpressing, and triple negative receptor subtypes.

The Wnt/β-catenin pathway is constitutively active and promotes multiple tumor processes, including breast cancer metastasis. However, the underlying mechanism by which the Wnt/β-catenin pathway is constitutively activated in breast cancer metastasis remains unclear. Inhibition of Wnt antagonists is important for Wnt/β-catenin signaling activation, and post-transcriptional regulation of these antagonists by microRNAs (miRNAs) might be a possible mechanism underlying signaling activation.

Currently, the aim of differentiating malignant from benign breast tumors and diagnosing early breast cancer is more accurately fulfilled with the addition of ultrasound (US) scans. Some studies have shown that three-dimensional (3D) imaging opens a new diagnostic window because of a better and more detailed impression of the spatial arrangement of focal breast masses. Therefore, we carried out this study to assess the efficacy of 3D-US diagnostic techniques for the detection of breast cancer using systemic analyses. Read More

Whole slide imaging is Food and Drug Administration-approved for primary diagnosis in the United States of America; however, relatively few pathology departments in the country have fully implemented an enterprise wide digital pathology system enabled for primary diagnosis. Digital pathology has significant potential to transform pathology practice with several published studies documenting some level of diagnostic equivalence between digital and conventional systems. However, whole slide imaging also has significant potential to disrupt pathology practice, due to the differences in efficiency of manipulating digital images vis-à-vis glass slides, and studies on the efficiency of actual digital pathology workload are lacking.
