BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. Chemokines play important roles in the progression of many malignancies; however, the role of chemokine receptor expression in clinical cases of PDAC is unclear. Moreover, little is known about DARC, a decoy receptor of CXC chemokines, in the regulation of tumor progression. METHODS: Functions of chemokine receptors were evaluated using surgical specimens collected from PDAC patients, and PDAC cell lines...

BACKGROUND: Differences in genetics and receptor expression (phenotypes) of invasive ductal breast cancer (IDC) impact on prognosis and treatment response. Immunohistochemistry (IHC), the most used technique for IDC phenotyping, has some limitations including its invasiveness. We explored the possibility of contrast-enhanced positron emission tomography magnetic resonance (CE-FDG PET/MR) to discriminate IDC phenotypes. METHODS: 21 IDC patients with IHC assessment of oestrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor-2 (HER2), and antigen Ki-67 (Ki67) underwent CE-FDG PET/MR...

BACKGROUND: The incidences of both thyroid cancer and breast cancer have been rising in recent years; however, it is very rare to find a single person with both of these cancers. Only a few cases of synchronous thyroid and breast cancer have been published, and even fewer cases have been reported in older patients (>60 years). CASE SUMMARY: The current study presents a case of synchronous papillary thyroid carcinoma and breast ductal carcinoma in an elderly patient...

Pancreatic cancer is the fourth most common cause of cancer-related mortality. Novel molecular biomarkers need to be identified for personalized medicine and to improve survival. The aim of this study was to examine chloride intracellular channel 4 (CLIC4) and Indian Hedgehog (Ihh) expression in benign and malignant lesions of the pancreas and to examine the eventual association between CLIC4 and Ihh expression, with clinicopathological features and prognosis of pancreatic cancer. A retrospective study of specimens collected from January 2000 to December 2011 at the Department of Pathology of the Second and Third Xiangya Hospitals, Central South University was undertaken to explore this question...

BACKGROUND: The recent investigations have rendered microRNAs (miRs) as a novel biomarker in cancer research. In fact, alteration in miR expression may be associated with tumor suppression, tumorigenesis, metastasis, and poor prognosis in human breast cancer (BC). OBJECTIVES: The aim of this clinical experimental study was to measure the miR-328 expression level in breast cancer tissues, at first. Then, we tried to find out any possible correlation between miR-328 and prognostic and predictive biomarkers in BC...

BACKGROUND: Up to 90% of patients undergoing breast cancer surgery suffer from seroma formation, which can cause discomfort and various complications after mastectomy. This retrospective observational cohort study aimed to elucidate whether flap fixation with fibrin sealant (ARTISS) tissue glue reduces seroma formation and seroma aspiration after mastectomy when compared with flap fixation using Vicryl sutures and when compared with a conventional wound closure technique. METHODS: All patients undergoing mastectomy due to invasive breast cancer or ductal carcinoma in situ were eligible for inclusion...

OBJECTIVE: We hypothesize that radiologists' estimated percentage likelihood assessments for the presence of ductal carcinoma in situ (DCIS) and invasive cancer may predict histologic outcomes. MATERIALS AND METHODS: Two hundred fifty cases categorized as BI-RADS category 4 or 5 at four University of California Medical Centers were retrospectively reviewed by 10 academic radiologists with a range of 1-39 years in practice. Readers assigned BI-RADS category (1, 2, 3, 4a, 4b, 4c, or 5), estimated percentage likelihood of DCIS or invasive cancer (0-100%), and confidence rating (1 = low, 5 = high) after reviewing screening and diagnostic mammograms and ultrasound images...

BACKGROUND: Tumor hypoxia induces the expression of several genes via the hypoxia-inducible transcription factor-1 alpha (HIF-1a). It is associated with the prognosis of several cancers. We studied the immunohistochemical expression of HIF-1a in patients with invasive ductal cancer (IDC) of the breast and the possible correlation with the maximum standardized uptake value of the primary tumor (pSUVmax) as well as other biological parameters. Prognostic significance of pSUVmax and expression of HIF-1a for the prediction of progression-free survival (PFS) was also assessed...

OBJECTIVES: Pancreatic ductal adenocarcinoma arises from the following 3 distinct precursor lesions: pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm (MCN). Genetic abnormalities in the first 2 precursor lesions have been well characterized, but there are limited data on progression pathways in MCNs. This study aimed to characterize genomic differences between MCNs with low-grade (LG) and high-grade (HG) dysplasia or carcinoma...

Papillary breast lesions are a heterogeneous group of tumors which mainly arise in the central mammary region, ranging from benign to malignant. Among them, solid papillary carcinoma (SPC) represents a very uncommon variant with indolent clinical behavior and excellent prognosis. The categorization of papillary lesions as benign, atypical or malignant is often difficult even for experienced pathologists. Furthermore, for prognostic purposes, to decide whether to consider a lesions as in situ when it is not associated with frank invasive foci of carcinoma may be problematic...

A pathological complete response in a patient affected by multiple synchronous, breast and lung primary malignancies is reported. A 63-year-old woman presented with an invasive ductal carcinoma of the breast and a lung adenocarcinoma. After multidisciplinary discussion, the patient underwent pulmonary left lower lobectomy followed by radio-chemotherapy with cisplatin and vinorelbine and started hormone therapy with letrozole. Ten months later, a left mastectomy with axillary lymph nodes dissection was performed...

BACKGROUND: The role of postmastectomy radiotherapy (PMRT) for women with pT3N0M0 breast cancer is controversial. We sought to determine the benefit of PMRT in this cohort using the National Cancer Database (NCDB). METHODS: We analyzed women with pT3N0M0 breast cancer who received mastectomy with or without PMRT between 2004 and 2012. We excluded men, women ≤18 years, neoadjuvant or unknown radiation or chemotherapy status, unknown estrogen or progesterone receptor status, unknown surgical margin status, histology other than invasive ductal or lobular carcinoma, and if death occurred <3 months after diagnosis...

INTRODUCTION: Breast cancer is the second most common cancer in the Indian female population. LABC and metastatic breast cancer are the most common stages at presentation in most low-resource countries. Although the incidence of LABC has decreased significantly in countries with enhanced resources thanks to widespread education and screening programs, it remains a daily encounter for surgeons and oncologists in low-resource countries. Neoadjuvant therapy has been studied widely for the treatment of LABC and is followed by locoregional therapy...

EDITORIAL
Alan Hollingsworth
Overdiagnosis in breast cancer has been a focus of increasing concern with wide ranges of calculations made indirectly through the study of prospective randomized trials and analyses of large registries. While most admit that some degree of overdiagnosis is inherent with ductal carcinoma in situ (DCIS), the rate of overdiagnosis with invasive disease is highly controversial. Although it is generally accepted that overdiagnosis is calculated through indirect means and deductive reasoning, this is not entirely the case...

High-grade pancreatic intraepithelial neoplasia (HG-PanIN) is the major precursor of pancreatic ductal adenocarcinoma (PDAC) and is an ideal target for early detection. To characterize pure HG-PanIN, we analysed 23 isolated HG-PanIN lesions occurring in the absence of PDAC. Whole-exome sequencing of five of these HG-PanIN lesions revealed a median of 33 somatic mutations per lesion, with a total of 318 mutated genes. Targeted next-generation sequencing of 17 HG-PanIN lesions identified KRAS mutations in 94% of the lesions...

INTRODUCTION: Modern full-field digital mammography (FFDM) appears to have increased the detection of breast microcalcification. This retrospective study aimed to assess whether this is associated with over-investigation and possible over-diagnosis of breast pathology of lesser significance. METHODS: Three 2-year periods were studied, in which different mammographic technologies were used exclusively viz., classical screen-film mammography (SFM) in 2003-04, computed radiography (CR) in 2009-10 and FFDM in 2012-13...

BACKGROUND: Many Western countries have long-established population-based mammography screening programs. Prior to implementing these programs, decision-analytic modeling was widely used to inform decisions. OBJECTIVE: The aim of this study was to perform a systematic review of cost-effectiveness models in breast cancer screening in the general population to analyze their structural and methodological approaches. METHODS: A systematic literature search for health economic models was performed in the electronic databases MEDLINE (Ovid), EMBASE, CRD Databases, Cochrane Library, and EconLit in August 2011 with updates in June 2013, April 2015, and November 2016...

The aim of this study was to find the differences and relationships between normal, atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS), and invasive ductal carcinoma (IDC) lesions of the breast based on biochemical characteristics determined by Raman spectroscopy (RS). After collecting 39 frozen sections from patients who underwent surgical resection or mammotome biopsy, nine normal tissues, seven ADH, eight DCIS, and 15 IDC lesions were detected using confocal RS. We then used leave-one-out cross-validation (LOOCV) and radial basis function (RBF) to build a support vector machine (SVM) diagnosis model...
