Predictive value of controlling nutritional status score in postoperative recurrence and metastasis of breast cancer patients with HER2-low expression.

Background: To investigate the predictive value of controlling nutritional status (CONUT) score in Postoperative Recurrence and Metastasis of Breast Cancer Patients with HER2-Low Expression.

Methods: The clinicopathological data of 697 female breast cancer patients who pathology confirmed invasive ductal carcinoma and surgery in Harbin Medical University Tumor Hospital from January 2014 to January 2017 were retrospectively analyzed. The relationship between CONUT score and various clinicopathological factors as well as prognosis was evaluated.

The tremendous clinical potential of the microbiota in the treatment of breast cancer: the next frontier.

Although significant advances have been made in the diagnosis and treatment of breast cancer (BC) in recent years, BC remains the most common cancer in women and one of the main causes of death among women worldwide. Currently, more than half of BC patients have no known risk factors, emphasizing the significance of identifying more tumor-related factors. Therefore, we urgently need to find new therapeutic strategies to improve prognosis.

Correlation analysis between androgen receptor and the clinicopathological features and prognosis of mammary Paget's disease.

Purpose: Little is known about the prognostic value of androgen receptor (AR) status in mammary Paget's disease (MPD). The purpose of this study was to explore AR status and the distribution of molecular subtypes in MPD as well as the relationship between AR expression and clinicopathological factors and to evaluate its prognostic value.

Methods: We analyzed 170 MPD patients of varying subtypes.

Correlation analysis of lymphocyte-monocyte ratio with pathological complete response and clinical prognosis of neoadjuvant chemotherapy in patients with breast cancer.

Purpose: Inflammation plays an important role in tumor proliferation, metastasis, and chemotherapy resistance. Peripheral blood lymphocyte-monocyte ratio (LMR) has been reported to be closely associated with the prognosis of many tumors, such as certain hematologic malignancies and gastric cancer. However, the association in breast cancer is still not clear.

Silencing DSCAM-AS1 suppresses the growth and invasion of ER-positive breast cancer cells by downregulating both DCTPP1 and QPRT.

Breast cancer (BC) remains a significant threat to the health of women; however, the mechanism underlying the initiation and progression of BC is poorly understood. We analyzed data from the Gene Expression Omnibus database and The Cancer Genome Atlas datasets to identify differentially expressed genes between BC and normal tissues. The roles of dCTP pyrophosphatase 1 (DCTPP1) and quinolinate phosphoribosyltransferase (QPRT) in BC cells were investigated after knocking down or overexpressing the genes.

Long non-coding RNA SATB2-AS1 inhibits microRNA-155-3p to suppress breast cancer cell growth by promoting breast cancer metastasis suppressor 1-like.

Background: Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) play vital roles in human cancers. Nevertheless, the effects of lncRNAs and miRNAs on breast cancer (BC) remain to be further investigated. This study was designed to testify the roles of lncRNA antisense transcript of SATB2 protein (SATB2-AS1) and microRNA-155-3p (miR-155-3p) in BC progression.

FSTL1 enhances chemoresistance and maintains stemness in breast cancer cells via integrin β3/Wnt signaling under miR-137 regulation.

FSTL1 is a protein coding gene associated with cell signaling pathway regulation and the progression of a variety of disorders. In this study, we hypothesized that FSTL1 increases oncogenesis in breast cancer by enhancing stemness and chemoresistance. RT-PCR and IHC revealed significantly higher FSTL1 mRNA and protein levels in TNBC than in non-TNBC specimens and in breast cancer cell lines.

HOXD3 Plays a Critical Role in Breast Cancer Stemness and Drug Resistance.

Background/aims: Homeobox D3 (HOXD3) is a member of the homeobox family of genes that is known primarily for its transcriptional regulation of morphogenesis in all multicellular organisms. In this study, we sought to explore the role that HOXD3 plays in the stem-like capacity, or stemness, and drug resistance of breast cancer cells.

Methods: Expression of HOXD3 in clinical breast samples were examined by RT-PCR and immunohistochemistry.

High-infiltration of tumor-associated macrophages predicts unfavorable clinical outcome for node-negative breast cancer.

The tumor microenvironment is composed of tumor cells, fibroblasts, endothelial cells and infiltrating immune cells, which may inhibit or promote tumor growth and progression. The objectives of this retrospective study were to characterize the density of tumor-associated macrophages (TAMs) in breast cancer, and to correlate the density of TAMs with clinicopathological parameters. Paraffin-embedded specimens and clinicopathological data, including up to 5 years follow-up information, were obtained from 172 breast cancer patients.

Expression of HOXD3 correlates with shorter survival in patients with invasive breast cancer.

Hox genes encode a family of homeodomain-containing transcription factors that determine cellular identity during development and which are also expressed in some types of cancer. The HOXD3 gene, a member of the Hox gene family, has been demonstrated to be expressed in several tumor cell lines, which exhibit enhanced invasion and metastasis through coordinate expression of metastasis-associated factors. However, the clinical impact of HOXD3 in breast cancer remains unclear.

Low expression of RECK indicates a shorter survival for patients with invasive breast cancer.

Expression cloning was used to initially isolate the reversion-inducing cysteine-rich protein with Kazal motifs (RECK) gene as a suppressor of transformation. The gene was found to encode a membrane-anchored regulator of MMPs. Experimental studies showed that RECK can suppress tumor invasion, metastasis, and angiogenesis.

Evaluation of protein pigment epithelium-derived factor (PEDF) and microvessel density (MVD) as prognostic indicators in breast cancer.

Purpose: Angiogenesis, which plays an important role in tumor growth and metastasis, is regulated by a balance between angiogenic stimulators and inhibitors. Pigment epithelium-derived factor (PEDF), a secreted glycoprotein is an important inhibitor of angiogenesis. Although the precise mechanisms by which PEDF exerts its actions remain poorly understood, there is growing evidence supporting the role of PEDF as a candidate antitumor agent.

Low expression of reversion-inducing cysteine-rich protein with Kazal motifs (RECK) indicates a shorter survival after resection in patients with adenocarcinoma of the lung.

It has been reported that an endogenous matrix metalloproteinase (MMP) inhibitor, reversion-inducing cysteine-rich protein with Kazal motifs (RECK), is able to inhibit tumour angiogenesis, invasion, and metastasis through inhibition of MMP-2, MMP-9, and membrane type-1 (MT1)-MMP (MMP-14) secretion and activity. In this study, using quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR), we have analysed RECK expression levels in resected non-small-cell lung cancer (NSCLC) tissue and compared these data with the clinicopathological features of these patients to investigate the role of RECK in NSCLC. We have also analysed the expression of MMP-2, MMP-9, and MMP-14 and compared the data with those for RECK expression.

High MMP-1 mRNA expression is a risk factor for disease-free and overall survivals in patients with invasive breast carcinoma.

Background: Matrix metalloproteinase 1 (MMP-1) degrades extracellular matrix and thereby promotes tumor invasion and progression. In this study we examined the prognostic significance of tissue expression levels of MMP-1 mRNA in patients with invasive breast carcinoma.

Materials And Methods: We assessed the prognostic value of MMP-1 mRNA expression in tumor tissue specimens from 85 breast carcinoma patients with a median follow-up time of 38 months (range, 2-48 months).

Prognostic values of matrix metalloproteinase family expression in human colorectal carcinoma.

Background: We examined expression patterns of matrix metalloproteinase (MMP), tissue inhibitor of metalloproteinase (TIMP), and reversion-inducing cysteine-rich protein with Kazal motifs (RECK) in colorectal cancer tissues to assess their prognostic significance.

Materials And Methods: mRNA expressions of 17 MMPs, 4 TIMPs, and RECK were measured in 112 colorectal cancerous tissues, 20 normal mucosa tissues, and 11 metastatic liver lesions by real-time reverse-transcriptional-polymerase chain reaction. The protein level expressions were confirmed with immunohistochemistry.
