Active clinical trials for "Neoplasm Metastasis"

Study about the comparison of post-operative results of secondary alveolar grafts according to two age groups: early secondary (4 to 7 years) versus late secondary (8 to 11 years) using a recently proposed score based on post-operative 3D CT analysis. Comparison of the initial results of the graft in the two groups, with a reference 2D score and evaluation of the concordance between the results found with this score and those of the 3D score. Finally, comparison of graft bone densities and nasal floor level (using 3D visualization) on post-operative TDMs in the 2 groups. The aim of this study is to determine the optimal age for grafting using three-dimensional CT assessment.

The investigators collected the data from the investigators' center between January 2011 and October 2020. The study included all non-small cell lung cancer patients with surgically excised brain metastasis. The investigators analysis the correlation of gene mutation and the disease course.

This study investigates the diagnostic value of PET/MRI for cervical lymph node metastases from head and neck squamous cell carcinomas.

The goal of this observational study is to provide a feasible surgical strategy based on Nagata method for patients who require secondary revision surgeries and to verify its long-term aesthetic outcomes. The main question it aims to answer is: • Whether ear reconstruction surgery based on Nagata method can improve the unsatisfactory outcomes of primary reconstruction surgery? Participants who had accepted secondary ear reconstruction based on Nagata method in our department will be required to received questionnaires in the follow-up and their photographs will be collected for reconstructed ear evaluation of its realness through convolutional neural network (CNN) models we previously developed.

This study was a retrospective, non-interventional, longitudinal, descriptive study. This study did not have a key underlying hypothesis, rather it was designed to explore the onboarding and adherence of SPMS patients in Australia to Mayzent (siponimod) treatment. Initiating siponimod involves pre-screen tests, including a CYP2C9 genotype test to determine siponimod maintenance dosing, and patients underwent a 6-day titration prior to maintenance. The MSGo platform was developed to support onboarding. It is an integrated digital platform that functions as a patient support service.

The long-term outcome of patients resected for colorectal liver metastases (CLM) after neoadjuvant chemotherapy (CHT) depends by several tumoral and non-tumoral factors, such as the immune response to the tumor and to the CHT. The aim of this study was to investigate the impact of the pathological and immunological response in patients undergoing liver resection for CLM after CHT in regards to the long-term outcome.

This is a non-interventional diagnostic, international, multicenter and non-comparative study of EGFR mutation status in aNSCLC patients (locally advanced and/or metastatic disease) with adenocarcinoma and non-adenocarcinoma histologies. This study will be conducted in Japan and Europe and will assess the concordance of EGFR mutation status derived from tumour samples and blood based circulating free DNA. The data generated will inform the use of less-invasive sample types in diagnostic practice. The study also aims to assess the current status of EGFR mutation testing across Japan and Europe and gaps in currently available data including EGFR mutation frequency in particular populations and demographic subgroups, EGFR mutation frequency in histological subtypes of NSCLC, EGFR mutation test process and methodology, utility of multiple sample types in the assessment of EGFR mutation status, and impact of EGFR mutation status on therapy choice. The data may be used to drive improvements to the EGFR mutation testing process, ensuring that patients have access to testing and are treated appropriately on the basis of the molecular features of their disease.

Shear Wave Elastography (SWE™) is a quantitative elastography method for measuring tissue stiffness. The difference in stiffness between benign and malignant tumors has been demonstrated by other elastography methods (acoustic radiation force impulse imaging, transient elastography and/or magnetic resonance elastography). The investigators hypothesized that benign liver tumors are softer than malignant liver tumors measured by SWE™, allowing differentiation between the two by tumor stiffness expressed in kilopascal (kPa). In this study benign and malignant liver tumors will be evaluated in five groups: 1) hemangioma and 2) focal nodular hyperplasia (FNH) representing the most common benign liver tumors; 3) metastases and 4) cholangiocarcinoma (CCC), both presenting malignant tumors mostly appearing in otherwise healthy liver, and 5) hepatocellular carcinoma (HCC) mostly occurring in cirrhotic liver, which can potentially influence elastographic measurements therefore querying the appropriateness of comparison between tumors in healthy and cirrhotic liver. Enrolled patients will undergo transabdominal ultrasonography and SWE™ examination. The tumor stiffness will be measured five times for each tumor. Additionally, surrounding liver parenchyma stiffness will be measured. The nature of the liver tumor will be defined through a standard diagnostic workup according to current guidelines, including contrast enhanced multi-slice CT, MRI and/or cytology/histology, as applicable. In the final analysis the mean tumor stiffness and tumor-parenchyma ratio will be calculated for each group as well as for benign and malignant tumors separately, and cut-off values for the differentiation of various groups will be derived. The clinical value of the method will be appraised based on specificity, sensitivity, positive and negative predictive values, and AUC.

The goal of this study is to better understand gender differences in end-of-life communication between physicians and patients with advanced cancer in the hospital.

This study aims to assess changes in vascular permeability in the brain tumor, and in the surrounding brain, due to radiation therapy, using Magnetic Resonance Imaging (MRI).
