The Combining Effects of Cell-Free Circulating Tumor DNA of Breast Tumor to the Noninvasive Prenatal Testing Results: A Simulating Investigation.

Massively parallel sequencing of circulating fetal DNA in the plasma of pregnant women is a common method for noninvasive prenatal testing (NIPT) of fetal trisomy 13, 18, and 21. However, circulating DNA is not restricted to pregnant women, with increased levels of plasma DNA also frequently detected in the plasma of cancer patients. Among pregnant women whose NIPT results were inconsistent with the fetal karyotype, a small number of patients have subsequently been diagnosed with a previously undetected malignancy.

Endoscopic naso-leakage drainage: a safe and effective method for the management of intrathoracic anastomotic leakage after esophagectomy.

Background: Intrathoracic anastomotic leakage (IAL) remains a major complication of esophagectomy. Main non-surgical options of management include chest drainage and endoscope interventions. This study is aim to present our experience and assess the efficacy of endoscopic naso-leakage drainage (ENLD) in patients with IAL.

Neoadjuvant Bevacizumab plus Chemotherapy versus Chemotherapy Alone to Treat Non-Metastatic Breast Cancer: A Meta-Analysis of Randomised Controlled Trials.

Purpose: Results from previous randomised controlled trials (RCTs) investigating whether the addition of bevacizumab to neoadjuvant chemotherapy (NAC) could statistically significantly increase the pathological complete response (pCR) and to identify which subgroup would benefit most from such regimens have produced conflicting results. This meta-analysis was designed to assess the efficacy and safety of bevacizumab plus chemotherapy compared with chemotherapy alone in the neoadjuvant setting.

Methods: A literature search of MEDLINE, EMBASE, Web of Science, and the Cochrane library was performed to identify eligible studies.

CHRNA3 polymorphism modifies lung adenocarcinoma risk in the Chinese Han population.

Recent genome-wide association studies (GWASs) have identified 15q25.1 as a lung cancer susceptibility locus. Here, we sought to explore the direct carcinogenic effects of genetic variants in this region on the risk of developing lung adenocarcinoma (ADC).

Breast cancer association studies in a Han Chinese population using 10 European-ancestry-associated breast cancer susceptibility SNPs.

Background: Genome-wide association studies (GWAS) have identified various genetic susceptibility loci for breast cancer based mainly on European-ancestry populations. Differing linkage disequilibrium patterns exist between European and Asian populations.

Methods: Ten SNPs (rs2075555 in COL1A1, rs12652447 in FBXL17, rs10941679 in 5p12/MRPS30, rs11878583 in ZNF577, rs7166081 in SMAD3, rs16917302 in ZNF365, rs311499 in 20q13.

Mutational analysis of key EGFR pathway genes in Chinese breast cancer patients.

Background: The epidermal growth factor receptor (EGFR) is a potential therapeutic target for breast cancer; however, its use does not lead to a marked clinical response. Studies of non-small cell lung cancer and colorectal cancer showed that mutations of genes in the PIK3CA/AKT and RAS/RAF/MEK pathways, two major signalling cascades downstream of EGFR, might predict resistance to EGFR-targeted agents. Therefore, we examined the frequencies of mutations in these key EGFR pathway genes in Chinese breast cancer patients.

[Value of cardiac troponin I measurement in prediction of anthracycline-induced cardiotoxicity in breast cancer patients].

Objective: To evaluate the value of cardiac troponin I (CTnI) measurement in predicting anthracycline-induced cardiotoxicity in patients with breast cancer.

Methods: This study was conducted among 186 breast cancer patients receiving anthracycline-based chemotherapy. Serum cTnI concentrations before and after each cycle of the chemotherapy and the left ventricular ejection fraction (LVEF) before and at the 2nd, 4th and 6th months of the treatment were recorded.

HLA class II variants in Chinese breast cancer patients.

Alterations of human leukocyte antigen (HLA) class II molecules are relevant to the development of breast cancer and metastatic progression. However, the role of HLA class II polymorphisms in the pathogenesis and progression of breast cancer is unclear. This study aimed to investigate the association between HLA class II variants and breast cancer susceptibility and prognosis in a Chinese population.

[Effect of cellular immune supportive treatment on immunity of esophageal carcinoma patients after modern two-field lymph node dissection].

Background & Objective: Cellular immunity suppression is marked in patients with esophageal carcinoma, which may be resulted temporarily from surgical injury. This study was to evaluate the effect of cellular immune supportive treatment on cellular immunity of patients with esophageal carcinoma.

Methods: A total of 60 patients with thoracic esophageal carcinoma, received two-field dissection, were randomized into control group and trial (immune supportive treatment) group.

[Effects of MT1-MMP on the in vitro invasiveness of breast cancer cells].

Objective: To investigate the effect of membrane type-1 matrix metalloproteinase (MTI-MMP) on the invasive potential of breast cancer cell and analyze its mechanisms.

Methods: After treatment of breast cancer MDA-MB-453 cell line with concanavalin A ( ConA, 20 microg/ml) for 24 h, MT1-MMP protein was detected in cancer cells by Western analysis and immunocytochemistry. MDA-MB-453 cells were cultured with exogenous latent proMMP-2 and MMP-2 activity was analyzed by gelatin zymography.

Cyclin D1 overexpression in esophageal cancer from southern China and its clinical significance.

Little reports showed cyclin D1 changes in esophageal cancer from southern China. In this study, we detected cyclin D1 expression in esophageal carcinomas from southern China 61% and 35% cases showed increased expression of cyclin D1 in esophageal carcinomas and the adjacent epithelia, respectively. Significant difference for cyclin D1 expression was found between esophageal carcinomas and the adjacent epithelia.

[Significance of membrane type-1 matrix metalloproteinase expression in breast cancer].

Background & Objective: Recent researches manifested that MT1- MMP (Membrane type-1 matrix metalloproteinase) is essential for breast cancer invasion and metastasis, but there are few reports about the clinical value of MT1- MMP. This study was designed to investigate the clinical significance of MT1-MMP protein and mRNA expression in human breast cancers.

Methods: Forty-six human breast cancer tissues were collected.

[Expression correlation of Ki67 to P53,VEGF,and C-erbB-2 genes in breast cancer and their clinical significances].

Background & Objective: The proliferating antigen Ki67 is an important biological marker in cell proliferation. This study was designed to investigate the expressions of Ki67, P53, vascular endothelial growth factor (VEGF),and C-erbB-2 in breast cancer tissue, and their correlations with cliniopathological significance.

Methods: The expressions of Ki67,p53,VEGF,and C-erbB-2 in 151 cases of breast cancer were assessed by immunohisto-chemistry, and their correlations with clinicopathological factors were statistically analyzed.

[Matrix metalloproteinases and breast cancer].

Matrix metalloproteinases(MMPs) are a family of zinc-dependent proteinases involved in the degradation of the extracellular matrix. A great deal of studies showed that they have the important role in invasiveness and metastasis of breast carcinoma. It was recently reported that they also contribute to the genesis and development of primary breast carcinoma.
