The value of the improved percutaneous and intravenous contrast-enhanced ultrasound diagnostic classification in sentinel lymph nodes of breast cancer.

Background: Metastatic burden of sentinel lymph node (SLN) in breast cancer patient is the basis for the decision to choose SLN biopsy or axillary lymph node dissection (ALND). However, the diagnostic performance of the previous percutaneous contrast-enhanced ultrasound (P-CEUS) and intravenous contrast-enhanced ultrasound (IV-CEUS) pattern were not satisfied. This study aimed to establish new classification based on structural characteristics for P-CEUS and IV-CEUS of SLN in breast cancer and evaluate the diagnostic efficacy.

AI-Powered Segmentation of Invasive Carcinoma Regions in Breast Cancer Immunohistochemical Whole-Slide Images.

Aims: The automation of quantitative evaluation for breast immunohistochemistry (IHC) plays a crucial role in reducing the workload of pathologists and enhancing the objectivity of diagnoses. However, current methods face challenges in achieving fully automated immunohistochemistry quantification due to the complexity of segmenting the tumor area into distinct ductal carcinoma in situ (DCIS) and invasive carcinoma (IC) regions. Moreover, the quantitative analysis of immunohistochemistry requires a specific focus on invasive carcinoma regions.

Lnc NR2F1-AS1 Promotes Breast Cancer Metastasis by Targeting the MiR-25-3p/ZEB2 Axis.

Long noncoding RNAs (lncRNAs) substantially affect tumor metastasis and are aberrantly expressed in various cancers. However, its role in breast cancer (BC) remains unclear. A microarray assay of differentially expressed lncRNAs in epithelial-mesenchymal transition (EMT) and non-EMT cells was performed.

Novel anti-HER2 antibody-drug conjugates trastuzumab deruxtecan (DS-8201a) showed its effect in previously-treated HER2-low metastatic breast cancer, suggesting a promising future in HER2-low breast cancer. We retrospectively reviewed the clinicopathological data of 325 patients with stage I-III HER2 negative breast cancer who received neoadjuvant chemotherapy in the First Affiliated Hospital of Sun Yat-sen University from January 2016 to June 2021. In general, 91 patients (28.

The prognostic role of a phospho-Stathmin 1 signature in breast cancer treated with neoadjuvant chemotherapy.

Background: High expression of Stathmin 1 (STMN1) protein is related to a poor prognosis in various tumors, including breast cancer. In our previous study, a phospho-STMN1 signature was conducted to predict outcomes in adjuvantly treated breast cancer patients. This study aimed to explore the relationship of STMN1 expression with our phospho-STMN1 signature and the prognosis of patients treated with neoadjuvant chemotherapy (NACT).

Clinicopathologic and molecular features of vascular tumors in a series of 118 cases.

Aims: Vascular tumors are composed of benign, intermediate, and malignant lesions. The diagnosis is challenging because some entities demonstrate overlapping morphologies and harbor the same genetic alterations. We describe herein a cohort of vascular tumors with clinicopathologic, immunohistochemical, and molecular features.

Malignant adenomyoepithelioma of the breast: Two case reports and review of the literature.

Background: Malignant adenomyoepithelioma (AME) of the breast is a rare tumor in which malignancy can arise from either epithelial or myoepithelial components, or from both cell types. The incidence and prognosis of malignant AME of the breast are difficult to assess due to its rarity. Therefore, the optimal treatment for this disease is still controversial.

A Prognosis Marker SLC2A3 Correlates With EMT and Immune Signature in Colorectal Cancer.

SLC2A3 is a membrane transporter that belongs to the solute carrier family, whose function includes transmembrane transport and glucose transmembrane transport activity. To clarify the expression and role of SLC2A3 in colorectal cancer (CRC), we analyzed the TCGA and GEO databases and found that SLC2A3 mRNA levels were significantly higher in CRC tissues than that in adjacent non-tumor tissues. Furthermore, high expression of SLC2A3 predicted poor overall survival and disease free survival for CRC patients.

Hemangioblastoma: clinicopathologic study of 42 cases with emphasis on TFE3 expression.

Hemangioblastomas (HBs) histologically overlap with rearrangement-associated tumors, which present as alveolar architecture and clear or eosinophilic granular cytoplasm. However, whether TFE3 is expressed in HBs remains unexplored. Herein, we analyzed the clinicopathologic features of 42 HBs emphasizing studies of TFE3 expression.

The Potential Therapeutic Role of Exosomal MicroRNA-520b Derived from Normal Fibroblasts in Pancreatic Cancer.

Pancreatic cancer (PC) remains a major health concern, with conventional cancer treatments exerting little influence on the disease course. MicroRNA-520b (miR-520b) functions as a tumor suppressor in several types of human cancers, whereas its anti-tumor property in the context of PC is still fundamental. The aim of this study is to identify the potential therapeutic role of miR-520b, transferred by exosomes, derived from normal fibroblasts (NFs) in PC progression.

hsa_circ_001653 Implicates in the Development of Pancreatic Ductal Adenocarcinoma by Regulating MicroRNA-377-Mediated HOXC6 Axis.

Pancreatic ductal adenocarcinoma (PDAC) is an extremely aggressive pancreatic cancer with poor survival rate. Circular RNAs (circRNAs) signatures have been identified in some human cancers, but there are little data concerning their presence in PDAC. We investigated the role of hsa_circ_001653, a newly identified circRNA, in the development of PDAC.

fusion and internal tandem duplication in undifferentiated round cell sarcoma: a pathologic and molecular study of 5 cases.

Undifferentiated round cell sarcomas (URCSs) usually remained unclassified due to lack of known genetic abnormalities. Herein, we retrospectively collected 5 cases of URCSs and sought to investigate their unique clinicopathologic and molecular features for providing more accurate classification. There were 2 males and 3 females with age ranged from 7 months to 17 years.

GALNT6 suppresses progression of colorectal cancer.

Colorectal cancer (CRC) is one of the most common malignant tumors in the world. Invasion and metastasis are the main cause of mortality in most CRC patients. Polypeptide N-acetylgalactosaminyltransferase 6 (GALNT6) regulated glycosylation, which is frequently altered in cancers, and play an important role in cancer development.

Colorectal cancer (CRC) is a major worldwide health problem due to its high prevalence and mortality rate. microRNA has been reported playing an important role in a variety of cancers including colorectal cancer. miR-203a-3p has been found up-regulated in CRC tissues compare with the adjacent normal tissues.

The clinicopathological significance of ZNF10 in invasive ductal carcinoma of the breast.

The aim of this study was to clarify the clinicopathological features and role of zinc finger protein 10 (ZNF10) in breast invasive ductal cancer (IDC). Our data first showed that ZNF10 expression was higher in 8 pairs of fresh breast IDC and breast cancer cell lines compared with their respective adjacent non-tumor breast tissues. ZNF10 expression was significantly higher in IDC compared with DCIS and fibroadenoma of the breast.

This study aimed to elucidate how miR-27a-3p modulates the Wnt/β-catenin signaling pathway to promote colorectal cancer (CRC) progression. Our results showed that the expression of miR-27a-3p was up-regulated in CRC and closely associated with histological differentiation, clinical stage, distant metastasis and CRC patients' survival. miR-27a-3p mimic suppressed apoptosis and promoted proliferation, migration, invasion of CRC cells and .

The interaction of hepatoma-derived growth factor and β-catenin promotes tumorigenesis of synovial sarcoma.

To clarify the clinicopathological and biological role of hepatoma-derived growth factor (HDGF) and β-catenin in synovial sarcoma. Our results showed that histological type and HDGF/β-catenin expression were the two important independent prognostic factors for overall survival in synovial sarcoma patients. HDGF knockdown dramatically inhibited cellular proliferation, colony formation, and migration but induced G1 phase arrest and apoptosis in SW982 cells.
