OBJECTIVES: To determine the malignancy rate overall and for specific BI-RADS descriptors in women ≥70 years who undergo stereotactic biopsy for calcifications. METHODS: We retrospectively reviewed 14,577 consecutive mammogram reports in 6839 women ≥70 years to collect 231 stereotactic biopsies of calcifications in 215 women. Cases with missing images or histopathology and calcifications associated with masses, distortion, or asymmetries were excluded. Three breast radiologists determined BI-RADS descriptors by majority...

BACKGROUND: We previously showed that pancreatic stellate cells (PSC) secreted interleukin (IL)-6 and promoted pancreatic ductal adenocarcinoma (PDAC) cell proliferation via nuclear factor erythroid 2 (Nrf2)-mediated metabolic reprogramming. Epithelial-mesenchymal transition (EMT) is a key process for the metastatic cascade. To study the mechanism of PDAC progression to metastasis, we investigated the role of PSC-secreted IL-6 in activating EMT and the involvement of Nrf2 in this process...

We report a case of tamoxifen associated macular hole with typical optical imaging and clinical features. A 53-year-old woman came to our department for gradual decrees of vision acuity in both eyes for 3 months after 30 months low-dosage-tamoxifen treatment as adjuvant treatment for invasive ductal breast carcinoma. Her best corrected visual acuity (BCVA) was 0.4 in the right eye and 0.12 in the left eye. Dilated fundus examination showed macular multiple, fine, crystalline deposits and small white points in retina of both eyes...

Breast cancer is a heterogeneous disease with very different responses to therapy and different length of survival. In many cases, however, the determination of the stage and histopathological characteristics of breast cancer is insufficient to predict prognosis and response to treatment for the vast heterogeneity of the disease. To understand the molecular signature of subtypes of breast cancer, we attempted to identify the methylation status of key tumour suppressor gene Ras association (RalGDS/AF-6) domain family member 1 isoform a (RASSF1A) and a member of the paired-like homeodomain transcription factor family which functions in left-right asymmetry development (PITX2) and to correlate results with known clinicopathological features of breast cancer...

Literature on non-ampullary-duodenal carcinomas is limited. We analyzed 47 resected non-ampullary-duodenal carcinomas. Histologically, 78% were tubular-type adenocarcinomas mostly gastro-pancreatobiliary type and only 19% pure intestinal. Immunohistochemistry (n=38) revealed commonness of 'gastro-pancreatobiliary markers' (CK7 55, MUC1 50, MUC5AC 50, and MUC6 34%), whereas 'intestinal markers' were relatively less common (MUC2 36, CK20 42, and CDX2 44%). Squamous and mucinous differentiation were rare (in five each); previously, unrecognized adenocarcinoma patterns were noted (three microcystic/vacuolated, two cribriform, one of comedo-like, oncocytic papillary, and goblet-cell-carcinoid-like)...

BACKGROUND: Pancreatic ductal adenocarcinoma is a highly aggressive disease with 5-year overall survival not exceeding 5%. In the Czech Republic, the incidence of this tumor has been increasing; according to recent statistics, the Czech Republic is already number one worldwide in the occurrence of this malignancy. Delayed diagnosis due to asymptomatic course of the disease in the early stages is characteristic for this disease. AIM: The objective of this article is to give an overview of the most important factors, which according to current knowledge of pancreatic adenocarcinoma have a prognostic and predictive potential...

Purpose: To assess the visibility of breast micro-calcifications using ultrasonography (US) and the accuracy and clinical usefulness of vacuum-assisted biopsy (VAB) using US guidance (USVAB) as compared to stereotactic guidance (SVAB). Materials and Methods: The study material comprised 158 retrospectively reviewed micro-calcification cases examined with US before VAB. The pre-biopsy US positivity frequency distributions were calculated, and the sensitivity, specificity and accuracy of VAB determined by comparing VAB histology with the surgical pathology or a 12-month follow-up...

BACKGROUND: Serum cancer antigen 19-9 (CA19-9) provides additional information about mucinous cystic pancreatic neoplasm (MPN). This study was undertaken to assess both CA19-9 and carcinoembryonic antigen (CEA) serum concentrations in consecutive patients affected by MPNs and other chronic benign and malignant pancreatic diseases. We also evaluated whether serum CA19-9 and CEA determinations provide additional information such as the presence of invasive carcinoma in MPN patients. METHODS: Serum CA19-9 and CEA from 91 patients with pancreatic diseases were tested by commercially available kits at the time of diagnosis...

The heterogeneous nature of ductal carcinoma in situ has been emphasised by data for breast-cancer screening that show substantial increases in the detection of early-stage non-invasive breast cancer but no noteworthy change in the incidence of invasive and distant metastatic disease. Indolent non-progressive forms of ductal carcinoma in situ are managed according to similar surgical strategies as high-risk disease, with extent of resection dictated by radiological and pathological estimates of tumour dimensions...

BACKGROUND: Prospective studies have identified obstructive sleep apnea (OSA) as a risk factor for increased overall cancer incidence and mortality. The potential role of OSA in the risk or progression of specific cancers is not well known. We hypothesized that pathological differences in pancreatic cancers from OSA cases compared to non-OSA cases would implicate OSA in pancreatic cancer progression. METHODS: We reviewed the medical records of 1031 patients who underwent surgical resection without neoadjuvant therapy for pancreatic ductal adenocarcinoma (PDAC) at Johns Hopkins Hospital between 2003 and 2014 and compared the TNM classification of their cancer and their overall survival by patient OSA status...

Most pancreatic cancers and extrahepatic cholangiocarcinomas are unresectable at the time of diagnosis, and even in case of a resectable cancer, for elderly or patients with coexistent comorbidities, surgery is not an option. Current treatment alternatives in these scenarios are very limited. Biliary stenting with self-expanding metal stents (SEMS) is the mainstay palliative treatment of biliary obstruction due to unresectable pancreatic cancer or cholangiocarcinoma. Nevertheless, more than 50% of SEMS become occluded after 6 mo due to tumour over- and ingrowth, leading to hospital readmissions and reinterventions that significantly impair quality of life...

Breast cancer metastases to the gastrointestinal tract are very rare occurrences. Among the histological subtypes of breast cancer, invasive lobular carcinomas have a high capacity of metastasis to uncommon sites including the stomach. Conversely, there has not been sufficient evidence supporting the gastric metastasis of invasive ductal carcinoma. Herein, we report a unique case of metastatic ductal breast carcinoma mimicking primary linitis plastica in a male patient, particularly focusing on the clinical and pathological features of presentation...

BACKGROUND: Ductal carcinoma in situ of the male breast is an unusual lesion and most often associated with invasive carcinoma. On rare occasions when the in situ component is present in pure form, histological grade is almost always low to intermediate. Imaging for these patients is difficult as gynecomastia is often present and can mask underlying calcifications or carcinoma. CASE REPORT: We report a case of pure high-grade ductal carcinoma in situ of the male breast in a patient with clear nipple discharge...

In addition to oncogenic drivers, signaling nodes can critically modulate cancer-related cellular networks to strength tumor hallmarks. We identify G-protein-coupled receptor kinase 2 (GRK2) as a relevant player in breast cancer. GRK2 is up-regulated in breast cancer cell lines, in spontaneous tumors in mice, and in a proportion of invasive ductal carcinoma patients. Increased GRK2 functionality promotes the phosphorylation and activation of the Histone Deacetylase 6 (HDAC6) leading to de-acetylation of the Prolyl Isomerase Pin1, a central modulator of tumor progression, thereby enhancing its stability and functional interaction with key mitotic regulators...

OBJECTIVES: Breast cancer is a heterogeneous disease consisting of distinct histopathological subtypes with different clinical outcomes. In this article, we identified the automated breast volume scanning (ABVS) and shear wave velocity (SWV) characteristics of different pathological types of breast carcinoma. METHODS: A retrospective review of both ABVS and SWV imaging of 118 consecutive breast masses was performed. The imaging features of both techniques were assessed with reference to histopathological results...

BACKGROUND: The diagnosis and management of lobular neoplasia (LN) including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) remains controversial. Current management options after a core needle biopsy (CNB) with lobular neoplasia (LN) incorporating both ALH and LCIS include excision biopsy or careful clinical and radiologic follow up. METHODS: A retrospective analysis of the surgical database at Cork University Hospital was performed to identify all core needle biopsies from January 1st 2010 to 31st December 2013 with a diagnosis of FA who subsequently underwent surgical excision biopsy...
