Surgery and Whole Brain Radiotherapy (RT) Versus Whole Brain Radiotherapy (RT) and Radiosurgery...
MetastasesCancerPatients in good general condition with resectable brain metastases, looks better with more intense treatment of metastases. This local treatment has been accomplished with surgery or radiosurgery. However, there are no randomized studies comparing these two types of treatment. The purpose of this study is to make this.
Phase II Study Evaluating Strategies of Lung Surveillance of Patients Operated of High Grade Soft...
Soft Tissue SarcomaLung MetastasisCancer surveillance has a significant cost and generate anxiety for the patient. It is important to avoid exams that will not modify health support or whose results wont allow to decide.
Prophylactic Cranial Irradiation (PCI) Versus no PCI in Non Small Cell Lung Cancer After a Response...
Brain MetastasesPatients with confirmed advanced NSCLC and any response to 3-6 cycles of chemotherapy, were randomized to receive PCI (30 Gy/10fr) or no PCI. The primary endpoint was the cumulative incidence of symptomatic brain metastases (BM) . The study was sized to detect a hazard ratio of 0.37 with 80% power and 2-sided 5% significance (60 events, 206 patients).
The Role of Fluorothymidine Positron Emission Tomography (FLT-PET) in Proliferation of Colorectal...
Colorectal NeoplasmsLiver NeoplasmsThe aim of the study is to obtain information on FLT used in a PET-scan as a marker for the proliferation of colorectal liver metastases, so that the risk of recurrence can be identified in a noninvasive way, concerning patients with resectable colorectal liver metastases. The hypothesis of this study is that a higher uptake of FLT in the liver metastases has a good correlation with the proliferation rate of the metastases. This rate is related to the risk of recurrence.
A Clinical Prospective Study to Validate a Risk Scoring Model for the HMGC After Curative Surgery...
Predictive Cancer ModelHepatic Metastasis1 moreA previous study of investigators established a risk scoring model for the occurrence of postoperative hepatic metastases in patients who underwent curative gastrectomy directly without neoadjuvant therapy. In order to further validate the clinical applicability of abovementioned model, investigators designed this prospective study, which also included patients who received neoadjuvant therapy before surgery, with the aim of exploring the applicability of the risk scoring model to this group of patients.
Role of FDG PET/CT in Patients With Metastasis of Unknown Origin
MetastasisEvaluatation of the role of F18FDG-PET/CT in patients with metastases of unknown origin.
CirculAting Tumor DNA in Patients DIagnosed With Lung Metastasis From Colorectal Cancer: candiDate...
Colorectal CancerLung MetastasesThe investigators will detect circulating tumor DNA in blood of patients with lung metastases from colorectal cancer using NGS technology and intend to use it for predicting the outcome of local treatment (surgery or radiation) and recurrence of lung metastases.
Independent Risk Factors Analysis and Model Construction For Recurrence After Radiofrequency/Microwave...
Colorectal Cancer With Liver MetastasesThis study is a retrospective, multicenter clinical study. The main objective is to analyze the risk factors affecting the recurrence of colorectal cancer patients with liver metastases who received radiofrequency/microwave ablation. Finally, we will construct a recurrence risk prediction model based on the risk factors and validated the model.
Ultrasound Radiomics for Predicting Breast Cancer and Axillary Lymph Node Metastasis
Breast CancerAxillary Lymph Node MetastasisThe project is proposed based on multimodal ultrasonic imaging omics building used for accurate prediction of the breast cancer and axillary lymph node metastasis load artificial intelligence forecasting model, this method can dig the hidden features of ultrasonic image is not visible to the naked eye, make up the subjectivity in the process of clinical doctors in diagnosis and treatment, provide accurate, objective basis for clinical decision making.
Imaging Features for the Risks for Recurrence After Stereotactic Radiosurgery in Brain Metastasis...
Brain MetastasesRadiosurgeryThis trial uses multi-parametric magnetic resonance imaging (MRI) to develop and validate imaging risk score to predict radiation necrosis in participants with brain metastasis treated with radiation therapy. Diagnostic procedures, such as multi-parametric magnetic resonance imaging (MRI), may improve the ability to diagnose radiation necrosis early and help establish treatment strategies.
