Quercetin is a naturally existing compound and shows attractive anticancer properties for a variety of solid tumors including glioma, bladder cancer, hepatocellular carcinoma, breast cancer, hematological malignancies and prostate carcinoma. However, these anticancer properties have not been clinically approved due to unclear mechanistic information and its low bioactivity. In our previous study, we elucidated that quercetin activates AMPK pathway which is the major mechanism for its unique anticancer effect in bladder cancer...

This study searched a rare and aggressive type of cancer in dogs and humans, the breast carcinosarcoma. Both clinical and pathological traits of mammary carcinosarcomas in dogs are similar to humans, such as infrequent occurrence, fast tumor growth, and unfavorable prognosis when compared to carcinomas. Other possible alterations include chromosomal abnormalities that can be useful for the identification of tumoral cells and diagnosis. The aim of this study was to compare the chromosomal features of peripheral lymphocytes and tumor cells in a mammary carcinosarcoma of a 14-year-old female Poodle...

P40 antibody has been shown to be a more specific squamous and basal cell marker compared with p63. As detection of myoepithelial cells (MECs) plays a critical role in breast pathology, and the fact that p40 targets an isoform of p63, this study was designed to compare these antibodies in a variety of lesions, especially those with an sclerotic stroma and carcinoma in situ. All studied lesions were selected from the daily cases of the 3 authors and stained with p63, p40, and calponin immunohistochemical stains...

OBJECTIVE: To determine the accuracy of fine-needle aspiration (FNA) and vacuum-assisted core biopsy (VACB) in assessing the presence of residual cancer in the breast after neoadjuvant systemic therapy (NST). SUMMARY BACKGROUND DATA: Pathologic complete response (pCR) rates after NST have improved dramatically, suggesting that surgery might be avoided in some patients. Safe avoidance of surgery would require accurate confirmation of no residual invasive/in situ carcinoma...

Secretory carcinomas of the breast are rare tumors with distinct histologic features, recurrent t(12;15)(p13;q25) translocation resulting in ETV6-NTRK3 gene fusion and indolent clinical behavior. Mammary analog secretory carcinomas arising in other sites are histopathologically similar to the breast tumors and also harbor ETV6-NTRK3 fusions. Breast secretory carcinomas are often triple (estrogen and progesterone receptor, HER2) negative with a basal-like immunophenotype. However, genomic studies are lacking, and whether these tumors share genetic features with other basal and/or triple negative breast cancers is unknown...

We aimed to evaluate whether obese women experience more advanced invasive breast carcinoma (IBC) with a higher number of involved lymph nodes, higher range of axillary lymph node ratio (LNR) and presence and size of extracapsular extension as it may have an impact on prognosis and management. 245 patients diagnosed with IBC were divided into normal weight (NW), overweight (OW) and obese (OB) groups. Patients were divided into high range of LNR (LNR over or equal to 0.2) and low LNR (LNR less than 0.2). The extracapsular extension dimensions were measured on the original slides of each case and grouped into ≤ 1 mm and > 1 mm...

Prakriti Shukla, Hanni Vasudev Gulwani
Dermatofibrosarcoma protuberans is a rare soft tissue sarcoma that arises from the dermis and invades deeper tissues. Usually, it behaves as an intermediate grade malignancy but in rare instances, it can metastasize. Frequent occurrences have been observed in trunk and extremities but involvement of the breast has rarely been reported. Therefore, dermatofibrosarcoma protuberans (DFSP) breast often masquerades primary breast malignancy on clinical and radiological grounds. Histomorphology and immunohistochemistry are helpful in making a definitive diagnosis...

Breast cancer is the leading malignancy and the second leading cause of cancer-related deaths. Axillary lymph node status is a very important prognostic factor in breast cancer patients; nodal evaluation is therefore a critical part of breast cancer management. Axillary lymph node dissection results in significant morbidity. Sentinel lymph node biopsy (SLNB) is being used in many centers to stage the axilla in planning axillary dissection management of patients and hence plays an important part in reducing morbidity among patients with carcinoma breast...

Some microRNAs have carcinogenic or tumor suppressive effects in breast cancer, which is the most common cancer in women worldwide. MiR-7 and miR-9 are tumor suppressor microRNAs, which induce apoptosis and inhibit proliferation in breast cancer cells. Moreover, miR-96 and miR-182 are onco-microRNAs that increase proliferation, migration, and tumorigenesis in breast cancer cells. This study aimed to identify the direct target genes of these four microRNAs in the human breast cancer cell lines MCF-7 and MDA-MB-231...

Finding new uses for existing drugs has become a new strategy for decades to treat more patients. Few traditional approaches consider the tissue specificities of diseases. Moreover, disease genes, drug targets and protein interaction (PPI) networks remain largely incomplete and the relationships between drugs and diseases conform to the triangularly balanced structure. Therefore, based on tissue specificities of diseases, we apply the triangularly balanced theory and the module distance defined for incomplete interaction networks to build drug-disease associations...

Background: Radiation therapy is an integral part of multimodality treatment for locally advanced carcinoma of breast. Radiation doses to nearby critical normal structures like heart, lungs, and contralateral breast (CLB increases risk of second malignancies. In this study, we measured doses to the CLB and studied effects of a 1 cm thickness superflap. Materials and Methods: Fifty post-mastectomy carcinoma breast patients were included in the study.Radiation therapy of 50 Gy was planned in 25 fractions, 5 days a week, using the Eclipse Treatment Planning System version 8...

Breast cancer is the prime cause for cancer mortality in women worldwide. The importance of diverse natural and dietary agents to reduce the risk of developing breast cancer is well established. Berberine, a natural isoquinoline alkaloid found in many medicinal plants is widely used in traditional Indian and Chinese medicine. Because of its capability to seize the cell cycle and induce apoptosis of numerous malignant cells, berberine has received considerable attention as a potential anticancer agent. In the present study, breast cancer was induced in Sprague Dawley (SD) rats by intragastric administration of 7, 12-dimethylbenz[a]anthracene (DMBA) at a dose of 80mg/kg of body weight...

The design, synthesis, and investigation of antitumor and anti-lipase activities of some coumarin-triazole hybrid molecules are reported. The synthesis of these hybrid molecules was performed under microwave irradiation and conventional heating procedures. The newly synthesized hybrid molecules were investigated as inhibitors against four tumor cell lines (BT20 human breast carcinoma, SK-Mel 128 melanoma, DU-145 prostate carcinoma, and A549 lung carcinoma) and porcine pancreatic lipase (PPL). Most of these compounds showed notable antitumor activities against the tested tumor cell lines, and compounds 8i and 8l showed the best anti-lipase activity of 99...

Early detection of breast cancer through screening can lower breast cancer mortality rates and reduce the burden of this disease in the population. In most western countries, mammography screening starting from age 50 is recommended. However, there is debate about whether breast cancer screening should be extended to younger women. This systematic review provides an overview of the evidence from RCT's on the benefits and harms of breast cancer screening with mammography in women aged 40 to 49 years. The quality of the evidence for each outcome was appraised using the GRADE approach...

Furanodienone, a major bioactive constituents of sesquiterpene derived from Rhizoma Curcumae, has been proven to possess the potent anticancer efficacy on human breast cancer cells. Here, we investigated the cytotoxicity of furanodienone on human colorectal carcinoma cell lines in vitro and in vivo, as well as its underlying molecular mechanisms in the induction of apoptosis. In this study, we found that furanodienone significantly inhibited proliferation of RKO and HT-29 cells, induced mitochondrial dysfunction characterized by collapse of mitochondrial transmembrane potential and reduction of ATP level, and promoted the production of reactive oxygen species (ROS) that functions upstream of caspase-dependent apoptosis...

For years, lobular carcinoma In Situ (LCIS) has been considered a high-risk marker for developing breast cancer. It is well known that ductal carcinoma In Situ is a precursor for the development of invasive ductal carcinoma, and ductal carcinoma In Situ is reported to be present in invasive ductal carcinoma in at least 40 per cent of cases. A similar relationship between LCIS and invasive lobular carcinoma (ILC) remains in question. This study evaluates the incidence of synchronous LCIS and ILC at our institution...

As the sequencing cost continued to drop in the past decade, RNA sequencing (RNA-seq) has replaced microarray to become the standard high-throughput experimental tool to analyze transcriptomic profile. As more and more datasets are generated and accumulated in the public domain, meta-analysis to combine multiple transcriptomic studies to increase statistical power has received increasing popularity. In this article, we propose a Bayesian hierarchical model to jointly integrate microarray and RNA-seq studies...

Nucleotide-binding oligomerization domain-like receptors (NLRs) are intracellular sensors of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). Previously, we reported nucleotide-binding oligomerization domain-containing protein 1 (NOD1) antagonists (11, 12) and a NOD2 antagonist (9) that sensitized docetaxel (DTX) or paclitaxel (PTX) treatment for breast or lung cancer. In this article, we describe for the first time a 1,4-benzodiazepine-2,5-dione (BZD) derivative (26bh) that acts as a dual NOD1/NOD2 antagonist and inhibits both nuclear factor κB (NF-κB) and mitogen-activated protein kinase (MAPK) inflammatory signaling, thereby adjuvanting PTX to suppress Lewis lung carcinoma (LLC) growth...
