(3D) Ultrasound Imaging Liver and Kidney
This study is to assess the addition of 3D ultrasound guidance during standard care ablation or biopsies of liver or kidney tumours. 3D ultrasound only differs from conventional 2D ultrasound in that the ultrasound transducer is mounted on a special assembly that moves the transducer in precise, stepped movements while …
Somatic Mosaicism in Twins Discordant for Childhood Cancer
Somatic mosaicism in cancer associated genes is one potential explanation for discordance in childhood cancer that has not been fully explored to date. This pilot study will focus on twins with central nervous system (CNS) tumors who are identified through the Children's Oncology Group's Project: EveryChild (PEC) registry or volunteer.
Development and Validation of a PSN-AI Prediction Model
Heterogeneity concerning survival in synchronous peritoneal metastasis from patients with colorectal cancer exists, thereby further classification is urgently required. This study aimed to validate a PSN-AI model based on DNA ploidy, stroma-tumor fraction, and nucleotyping (PSN) for the prediction of survival of synchronous peritoneal metastasis from colorectal cancer.
A Prospective Multicentre Clinical Study of Dynamic Monitoring of Plasma ctDNA Methylation Markers to Predict Recurrence of Colorectal Cancer After Complete Resection of Peritoneal Metastases
The goal of this clinical trial is to explore the predictive effect of postoperative plasma ctDNA methylation status on postoperative recurrence free survival (RFS) of colorectal cancer patients with peritoneal metastasis after R0/R1 resection. The main questions it aims to answer are: Preoperative and postoperative plasma ctDNA methylation detection (ColonAiQ) …
Prospective Single-center Study About the Use of ctDNA in the Management of Patients With Tumors of the Gastrointestinal Tract
This study will evaluate the use of ctDNA in the clinical management of patients with tumors of the gastrointestinal tract.
Acquisition of Blood and Tumor Tissue Samples From Patients With Gastrointestinal Cancer
Background Gastrointestinal cancers can occur in the throat, stomach, gallbladder, liver, pancreas, and colon. Researchers are interested in evaluating how active the immune system is in trying to fight the cancer by studying blood and tumor tissue donated from individuals who have been diagnosed with gastrointestinal cancers. Objectives To collect …
Prospective Cohort for Tumor Bed Boost Radiotherapy in HER2 Positive Breast Cancer
The purpose of this study is to analyze treatment outcomes related to tumor bed boost of postoperative radiation therapy in patient with HER2+ breast cancer who underwent breast conserving surgery. The main questions it aims to answer are: 7-year ipsilateral breast tumor recurrence 7-year disease-free survival 7-year locoregional recurrence 7-year …
Circulating Tumor DNA to Monitor Response to Neoadjuvant Chemotherapy in Breast Cancer
Investigators aim to investigate whether circulating tumor DNA is a sensitive marker to evaluate patients' response to neoadjuvant chemotherapy
Tumor Microenvironment in Gastric Cancer Patients Treated With Combined Immunotherapy and Chemotherapy
The goal of this study is to analyze the tumor microenvironment (TME) in gastric cancer patients treated with combined immunotherapy and chemotherapy. The main questions it aims to answer are: Provide profiles of TME between pre-treatment and post-treatment to gain insights into the mechanisms of immunotherapy combined with chemotherapy in …
CANPOS: Predictive Biomarkers of Tumor Progression in Non-small Cell Lung Cancer
CANPOS is a non-interventional study aiming at evaluate at the time of initial surgery the value of new serum markers to predict the occurrence of metastases in patients with early-stage non-small cell lung cancer. This would represent a rational to develop personalized follow-up and prevention strategies
