Tumor-infiltrating lymphocytes and immune checkpoint proteins such as PD-L1 are potential prognostic factors and therapeutic targets in breast cancer. Most studies characterizing the breast tumor immune microenvironment have focused on ductal carcinomas. Here we investigate the tumor microenvironment of primary invasive lobular carcinomas. Previously constructed tissue microarrays of 47 lobular carcinomas were labeled by immunohistochemistry for PD-L1, CD8, CD20, and FoxP3. The stromal immune infiltrate density was qualitatively scored as a percentage of tumor area: 1+ (<5%); 2+ (5-10%); 3+ (10-15%); or 4+ (>50%)...

BACKGROUND Phyllodes tumor (PT) is a rare neoplasm of the breast. Concomitant PT with invasive ductal carcinoma (IDC) is an even rarer occurrence. When ductal carcinoma in situ (DCIS) or IDC are detected within the specimen, the management changes from wide local excision to further staging work-up, including sentinel node biopsy and radiation. CASE REPORT We report the case of a 70-year-old presented with right breast mass whose pathology showed benign PT with concomitant IDC and DCIS. The patient elected for a wide excision of the mass with sentinel lymph node biopsy, which did not show any involvement...

PURPOSE: We report a very unique case of an esophageal metastasis from a pancreatic ductal adenocarcinoma (PDAC) primary. METHODS: After obtaining consent from the patient, all relevant records of the case were obtained and retrospectively reviewed. RESULTS: At presentation, the patient was diagnosed with synchronous pancreatic and esophageal cancer. He received six months of neoadjuvant therapy including FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and stereotactic body radiation therapy (SBRT) to the pancreatic tumor followed by a combined pancreaticoduodenectomy and Ivor Lewis esophagectomy...

Undifferentiated carcinoma of the pancreas with osteoclast-like giant cells (UCOGC) is currently considered a morphologically and clinically distinct variant of pancreatic ductal adenocarcinoma (PDAC). In this study, we report clinical and pathological features of a series of 22 UCOGC, including the whole exome sequencing of 8 UCOGC. We observed that 60% of the UCOGC contained a well-defined epithelial component and that patients with pure UCOGC had a significantly better prognosis than did those with an UCOGC with an associated epithelial neoplasm...

In pancreatic cancer (PC), adenosquamous carcinoma of the pancreas (PASC) containing both ductal adenocarcinoma and squamous carcinoma in the same tumor represents ~ 4% of the total incidence. To date, the genomic features of this mixed tumor are still unknown. We analyzed genomes of 17 PASCs and 34 ductal adenocarcinomas (PDACs), showing that PASC carried highly enriched TP53 mutations and 3p loss compared to PDAC. Furthermore, we uncovered that adenomatous and squamous components of PASC harbored comparable genomic alterations, suggesting that two cellular components are developed from the same progenitor cancer cells...

Circular RNAs (circRNAs) are a class of long, non-coding RNAs molecules that shape a covalently closed continuous loop which have no 5'-3' polarity and contain no polyA tail. CircRNAs also possess relatively jarless framework and are highly tissue-specific expressed in the eukaryotic transcriptome. Emerging evidences have discovered that thousands of endogenous circRNAs are present in mammalian cells and they mediate gene expression at the transcriptional or post-transcriptional level by binding to microRNAs or other molecules and then inhibit their function...

INTRODUCTION: Experimental evidences from the last 2 decades supports the existence of a special type of neoplastic cell with stem-like features [cancer stem cell (CSC)] and their role in the pathophysiology and therapeutic resistance of breast cancer. However, their clinical value in human breast cancer has not been fully determined. MATERIALS AND METHODS: An immunohistochemistry panel of 10 putative CSC markers (CD34, C-KIT, CD10, SOX-2, OCT 3/4, p63, CD24, CD44, CD133, and ESA/EPCAM) was applied to 74 cases of breast cancer, followed in a Regional Cancer Center of Minas Gerais State, Brazil, from 2004 to 2006...

Cancer cells can have different patterns of exon usage of individual genes when compared to normal tissue, suggesting that alternative splicing may play a role in shaping the tumor phenotype. The discovery and identification of gene variants has increased dramatically with the introduction of RNA-sequencing technology, which enables whole transcriptome analysis of known, as well as novel isoforms. Here we report alternative splicing and transcriptional events among subtypes of invasive ductal carcinoma in The Cancer Genome Atlas (TCGA) Breast Invasive Carcinoma (BRCA) cohort...

The utility and reliability of assessing molecular biomarkers for translational applications on pre-operative core biopsy specimens assume consistency of molecular profiles with larger surgical specimens. Whether DNA methylation in ductal carcinoma in situ (DCIS), measured in core biopsy and surgical specimens are similar, remains unclear. Here, we compared genome-scale DNA methylation measured in matched core biopsy and surgical specimens from DCIS, including specific DNA methylation biomarkers of subsequent invasive cancer...

Breast cancer is the leading cause of cancer death in women younger than 40 years. Triple-negative breast cancer (TNBC) and human epidermal growth factor receptor-2 (HER2) positive subtypes have a particularly poor prognosis in this age group. The purpose of this study was to compare rates of recurrence among breast cancer subtypes in young patients treated with modern adjuvant systemic therapy. A retrospective review of breast cancer patients managed at a major academic breast center between May 2000 and November 2014 was performed...

A 59-year-old woman with a remote history of invasive ductal carcinoma of the breast was found on a follow-up computed tomography scan of her brain to have a 1-cm lesion in the right frontal lobe in 2008. In the ensuing years, before her current admission, multiple imaging studies of the brain revealed that the lesion was stable and it was, therefore, interpreted as a small area of encephalomalacia related to a thrombosed cortical vein, a cavernoma, or treated metastatic breast cancer. In 2013, the patient underwent a bilateral salpingo-oophorectomy for ovarian tumors that were diagnosed as bilateral serous cystadenofibromas...
