Changes to Function and Quality of Life and Patient Experience for Patients Undergoing Treatments...
Recurrent Oropharynx CarcinomaThe purpose of this research project is to measure changes in communication, swallowing and quality of life and individual patient priorities which may happen over time in patients with a diagnosis of recurrent head and neck cancer, specifically recurrent cancer (cancer which has returned after previous treatment) of the back of the throat, the tonsils and/or the base of tongue (recurrent oropharyngeal cancer) and what it is like for patients and their significant others to experience these changes over time.

East Asian Breast Cancer Genome Atlas and Recurrence Risk Prediction
Breast CancerThis project aims to establish the cancer genome atlas and the platform of recurrence risk prediction specific for East Asian breast cancer patients. The study was planned to collect blood sample, fresh tumor tissue, and paraffin embedded tumor tissue from 2000 patients. Aims to identify unique genetic alterations in Asian tumors, to identify the susceptible genes for breast carcinogenesis in East Asia, and to establish the new platform for accurate prediction of recurrence. The investigator will explore the association of patient outcomes with the genetic alterations from the cancer atlas of East Asian breast tumors.

ctDNA Detection of MRD in Predicting Postoperative Recurrence in Biliary Tract Cancers:A Multicenter...
Biliary Tract CancerA substantial proporation of patients with biliary tract malignancies still experience disease recurrence after curative resection. ctDNA-based minimal residual disease (MRD) method has been widely used to monitor postoperative recurrence in solid cancers, but few studies have been reported in biliary tract cancers. The present clinical trial aims to elucidate the correlation between the postoperative ctDNA status and the prognosis of patients with biliary tract cancers, and evaluate whether ctDNA could better predict patients' recurrence and guide clinical practice.

Serum Glycomics as Prognostic and Diagnostic Biomarkers of Disease Recurrence in Liver Transplant...
Prognostic BiomarkerLiver Transplantation2 moreLiver transplantation (LT) is the only curative option for a selection of patients with hepatocellular carcinoma (HCC) based on clinical selection criteria known as the Milan criteria. Nevertheless, 15% of these patients still show tumour recurrence after LT. In a monocentric pilot study, we have demonstrated that specific changes in N-glycan profiles (measured before LT) occur in HCC patients receiving LT1. These specific changes proved to be strongly associated with the risk of HCC recurrence and overall death after LT, independent of the criteria used for stringent patient selection. Pathophysiologically, it is known that abberations in protein glycosylation are involved in the onset en development of HCC. As such, a prognostic biomarker was developed that can clearly differentiate between patients with and without increased risk of HCC recurrence. The primary goal of this research study is to set up a prospective, multicentre study in order to validate the prognostic value of this glycomics-based serum biomarker. As such, the risk of tumour recurrence in patients undergoing LT for HCC will be estimated independent from the Milan criteria and the French alpha-fetoprotein model as the current standard. The secondary goal is to explore the potential of serum glycomics as markers of early recurrence after LT for HCC. More specifically, we aim to investigate whether serial glycomics determination at fixed time points after LT could allow early detection of recurrent HCC even before it is visible on conventional imaging. Consequently, a diagnostic biomarker for monitoring early recurrence after LT could be developed with the potential of redirecting treatment strategies already in an early disease stage. In case the promising data from the pilot study will be confirmed, the prognostic biomarker could be implemented in daily clinical practice leading to optimization of patient selection using a simple blood test before LT. More specifically, this marker could improve organ allocation thus preventing unnessecary treatment toxicity for the patient and reducing the costs of treatment for society. Moreover, it should be emphasized that a patent application was already submitted and accepted in collaboration with TechTranfer of Ghent University (PCT/EP2021/057788-Prognostic markers of disease recurrence in liver transplant recipients with hepatocellular carcinoma).

Prospective Monitoring of Subjects With Biochemically Recurrent Prostate Cancer Using 18FDCFPyL...
Prostate CancerBiochemically RecurrentBackground: Prostate cancer is the second leading cause of cancer-related death in American men. The disease recurs in up to 50,000 men each year after their early-stage disease was treated; however, at this stage, imaging scans are often unable to find the disease in the body. In this natural history study, researchers want to find out if a new radiotracer (18F-DCFPyL) injected before positron emission tomography (PET) imaging can help identify sites in the body with cancer. Objective: To learn more about how 18F-DCFPyL PET/CT scans detect change over time in men with recurrent prostate cancer. Eligibility: Men aged 18 and older with prostate cancer that returned after treatment. Design: Participants will be screened with blood tests. They will also have a bone scan and a computed tomography (CT) scans of the chest, abdomen, and pelvis. Participants will have an initial study visit. They will have a physical exam and blood tests. They will have a PET/CT scan with 18F-DCFPyL. The radiotracer will be injected into a vein; this will take about 20 seconds. The PET/CT scan will be done 1 to 2 hours later. Participants will lie still on a scanner table while a machine captures images of their body. The scan will take 45 minutes. Participants will return for blood tests every 3 months. Participants will return for additional scans with 18F-DCFPyL on this schedule: Once a year if their previous scan was negative for prostate cancer. Every 6 months if their previous scan was positive for prostate cancer. Participants may be in the study up to 5 years.

A Performance Evaluation Study of Arquer's MCM5 Elisa Test (ADXBLADDER) to Aid in the Monitoring...
Bladder CancerThe objective of this prospective, multi-centre study is to evaluate the performance of ADXBLADDER, a urine MCM5 ELISA test, as an aid in the detection of bladder cancer recurrence. Patients undergoing cystoscopic surveillance in non-muscle invasive bladder cancer (NMIBC) follow-up will be recruited and asked to provide a urine sample to be tested with ADXBLADDER. To assess the diagnostic accuracy of the test, the MCM5 results will be compared with the gold standard cystoscopy and pathology of resected tissue.

Keeping Oral o Parental AnticoaguLation in the Acute Phase of Cardioembolic Ischemic Stroke
Cardioembolic StrokeAnticoagulant Therapy2 moreThis is an observational, prospective, multicenter, cohort study in patients with cardioembolic stroke and previous oral or parenteral anticoagulant therapy. Patients in which anticoagulante therapy is mantained will be compared to those in which it is interrupted, in terms of stroke or systemic embolism and haemorrhagic transformation.

Early Recurrences of Atrial Arrhythmias and Their Impact on Late Recurrence After Pulmonary Vein...
Atrial Fibrillation ParoxysmalRecurrenceThis is a prospective, single-arm study conducted in University Hospital of Split, Department of Cardiology. Patients treated with PFA for symptomatic paroxysmal atrial fibrillation will be asked to participate in the study. An implantable loop recorder (ILR) will be placed immediately after the PFA procedure for rhythm monitoring. Early recurrences will be subsequently divided into very early recurrences (up to 1 month post-procedure) and early recurrences (1-3 months post-procedure). Late recurrences will be defined as those 3 to 12 months post-procedure. Patients will be monitored routinely through follow up visits during which ILR will be interrogated and eventual symptoms will be assessed. Follow-up visits will be scheduled 1, 3, 6, 12 months post-procedure. Median follow-up will be 12 months. Data for the study will be obtained from a loop monitor to assess the arrhythmia burden during follow-up visits in the University Hospital of Split Arrhythmia Clinic.

Recurrence Markers, Cognitive Burden and Neurobiological Homeostasis in Late-Life Depression
Depression in Old AgeRecurrence1 moreLate-life depression (LLD) is associated with disability, increased risk for cognitive decline and dementia, elevated suicide risk, and greater all-cause mortality. These outcomes are related to depression being a recurrent disorder, with repeated episodes over a patient's lifetime. Recurrence rates (defined as including both relapse and recurrence) are high in LLD. The goals of this study are to identify neurobiological factors that predict recurrence risk, and examine how cognitive performance changes are both influenced by these neurobiological factors and also predict recurrence risk.
