Shear Wave Elastography Can Differentiate between Radiation-Responsive and Non-responsive Pancreatic Tumors: An ex Vivo Study with Murine Models

Neither contrast-enhanced computed tomography nor magnetic resonance imaging can monitor changes in the pancreatic ductal adenocarcinoma microenvironment during therapy. We hypothesized that shear wave elastography could overcome this limitation. To test this hypothesis, we measured the shear modulus of two groups of murine pancreatic tumors (KCKO, n  = 30; PAN02, n = 30) treated with stereotactic body radiation therapy (SBRT). The mean shear modulus of KCKO tumors was 7.651 kPa higher than that of PAN02 tumors (p

Authors: Zhou WP, Zan XY, Liu X, Sudarshan SKP, Yang SD, Fang XM, Guo YJ, Hu XY Abstract OBJECTIVE: To investigate the characterization of breast lesions using diffusion kurtosis model-based imaging. METHODS: This prospective study included 120 consecutive patients underwent preoperative DCE-MRI examinations and multi-b-value diffusion-weighted imaging (DWI). Among them, 88 malignant lesions and 44 benign lesions were detected, 56 normal fibroglandular breast tissue were selected as normal control. Conventional apparent diffusion coefficient (ADC), DKI-based parameters mean kurtosis (MK) and mean diffusivity (M...

Authors: Yang Q, Sun J, Ma Y, Zhao C, Song J Abstract Accumulating evidence showed that lncRNAs play important roles in tumour development. Recently, a novel lncRNA DLX6-AS1 was found to be overexpressed in some tumors such as lung adenocarcinoma, renal cell carcinoma and hepatocellular carcinoma. However, the functional roles of DLX6-AS1 in laryngeal squamous cell carcinoma (LSCC) are still unclear. In the study, we showed that the expression level of DLX6-AS1 was upregulated in the LSCC samples compared to the noncancerous tissues. By using CCK-8 analysis, we demonstrated that knockdown expression of DLX6-AS1 sup...

This study aimed to explore the regulatory role of ELFN1-AS1 in COAD and construct a gene delivery system based on extracellular vesicles (EVs). We found that ELFN1-AS1 levels were obviously increased in COAD patients and COAD tumor cells. Knockdown of ELFN1-AS1 expression by siRNA inhibited COAD cell proliferation and migration. Moreover, silencing ELFN1-AS1 significantly reduced the activation of extracellular signal-regulated protein kinase (Erk), up-regulated the protein expression of E-cadherin and down-regulated vimentin. In addition, we treated human umbilical cord mesenchymal stem cells (hUCMSCs) with siRNA-ELFN1-A...

There is lack of transcriptomic data of brain lesions from human lung adenocarcinoma patients. As part of the project to understanding the tumor microenvironment in brain metastasis of LUAD patients, we performed bulk RNA analysis on brain metastases from 6 LUAD patients. In order to understand the tumor intrinsic factors that potential shape the tumor microen...

Conclusion.A significant subset of patients with mPDAC can achieve long‐term survival (≥18 months) in 2018. We identified low NLR as a significant prognostic factor associated with long‐term survival in mPDAC.Implications for Practice.Metastatic pancreatic ductal adenocarcinoma (mPDAC) is one of the most lethal types of cancer. A subset of patients with mPDAC can achieve long‐term survival (≥18 months) with a modern chemotherapy regimen, such as FOLFIRINOX or gemcitabine/nab‐paclitaxel. We identified low neutrophil‐to‐lymphocyte ratio (NLR) as a significant prognostic factor associated with long‐term su...
