Active clinical trials for "Recurrence"

The present study in patients with Prostate cancer and biochemical failure after surgery and/or radical-postoperative Radio Therapy (RT) will evaluate if PET/CT with 18F-JK-PSMA-7 compared to PET-CT 18F-Choline is able to identify the early pattern of biochemical recurrence and/or metastatic sites, so that the patient could be better managed, with a benefit in survival.

The purpose of this study is to evaluate the efficacy and safety of Sintilimab in combination with Bevacizumab and Temozolomide in subjects with recurrent glioblastoma.

This study is a single arm, single center, prospective and open exploratory study. About 15 patients with recurrent hepatocellular carcinoma (HCC) after liver transplantation are expected to be enrolled.Patients will be treated with bevacizumab and FOLFOX4.Treatment was continued until disease progression, development of intolerable toxicities, death, withdrawal of consent, initiation of new antitumor therapy, whichever occurred first.

This is a a prospective, single-arm, and exploratory study of endoscopic resection of recurrent nasopharyngeal carcinoma via transoral retropterygoid approach.

Single-center, prospective, diagnostic trial in radically treated patients with biochemical recurrence of prostate cancer. Patients with radically treated prostate cancer with biochemical relapse and negativity of all traditional morphological and functional imaging (transrectal ultrasound, bone scan, 18F-FMC PET/CT, CT/MRI) or doubtful imaging of 2-deoxy-2-[fluorine-18] (18F)-fluoromethylcholine (FMC) PET/CT will receive a Gallio-68 (68Ga)- Prostate Specific Membrane Antigen (PSMA) Positron Emission Tomography (PET)/Computed Tomography (CT) scan.

This trial studies the side effects and best way to perform genetic testing in predicting biomarkers of recurrence in patients with prostate cancer undergoing surgery. Collecting and storing samples of tissue, blood, and other body fluids from patients to test in the laboratory and collecting information about the patient's health and treatment may help doctors learn more about cancer and help predict the recurrence of prostate cancer

This clinical trial studies positron emission tomography (PET)-computed tomography (CT) in determining the radiation dose delivered with radioactive spheres to patients with liver metastasis or primary liver or biliary cancer. Comparing results of diagnostic procedures dose before and after delivery of radioactive spheres to the liver may help determine radioembolization dose and plan the best treatment for liver metastasis or primary liver or biliary cancer.

Whether patients with stage III clear cell renal cell carcinoma (ccRCC) should receive adjuvant targeted therapy or not is still on debate. The investigators invented a multimodal recurrence scoring system that was successfully categorise patients with stage III clear cell renal cell carcinoma into high-risk and low-risk groups with Hazard Ratio (HR) of 6.21. Here the investigators randomly assign assay-defined high risk patients of locally advanced ccRCC into adjuvant targeted therapy group and observation group. Disease free survival and overall survival are the end points of observation.

Current international guidelines recommend a three-month blanking period after pulmonary vein isolation (PVI) for atrial fibrillation (AF). Early recurrence of atrial tachyarrhythmia (ERAT; comprising of AF, left atrial tachycardia and atrial flutter) is common, occurring in up to 65% of patients, but in the first month is generally thought not to predict long-term AF recurrence, and re-intervention is not recommended. Suggested causes for ERAT include inflammation and arrhythmogenic structural changes caused by ablation lesions. Early, purely inflammatory ERAT would not lead to late AF recurrence as pulmonary vein reconnection is established as the main factor associated with long-term recurrence in paroxysmal AF. Previous studies have shown ERAT in the second to third month (rather than first month) to be a stronger predictor of late AF recurrence, due to presumed reduction in the contribution of the acute inflammatory response after this. Biochemical data have shown that the post-ablation inflammatory phase is usually limited to the first month after both radiofrequency (RF) and cryoballoon (CB) ablation, though inflammatory markers have been shown to be less elevated following CB PVI. Histologically, lesions formed by the two modalities differ significantly. RF lesions are characterised by irregular boundaries and significant disruption to the endothelium, exposing the sub-endothelial layer and resulting in significant and sustained platelet activation, changes which can last for many months. CB lesions on the other hand, are observed as well demarcated and homogenous within one week, with reduced thrombogenicity, which may lead to reduced inflammation. ERAT following CB ablation cannot be accurately predicted by inflammatory response and it is postulated that endothelial function may play a role in the development of ERAT in such patients. Some studies have shown reduced recurrence rate and re-hospitalisation amongst the CB population, including the FIRE and ICE trial, potentially resulting in a better patient experience with CB and the possibility of a shorter blanking period. Post-ablation inflammatory response is more predictive of ERAT following RF than CB PVI, and the latter is considered to be associated with less inflammation. There is however, a paucity of data evaluating endothelial function post-AF ablation and its correlation with ERAT or late recurrences of arrhythmia. Given that earlier re-intervention in patients with ERAT in the third month of the blanking period can result in greater outcomes with respect to late recurrence of AF, if it can be demonstrated that endothelial function testing in the first few months post-CB PVI can be predictive of later ERAT, then shortening the blanking period following CB PVI and performing repeat ablation to control troublesome later ERAT may reduce overall patient morbidity and re-hospitalisation. The purpose of this novel pilot study is to examine the relationship between the post-ablation inflammatory response, endothelial function and timing and frequency of ERAT for patients undergoing RF and CB PVI for paroxysmal or short-lived persistent (less than 6 months' duration) AF. If the initial data provides hypothesis generating information, the aim would be to perform the study on a larger basis with higher statistical power to determine whether early post-ablation endothelial function testing can predict recurrences and identify those suitable for earlier re-intervention.

Study aims to compare the influence of intravenous lidocaine and peridural ropivacaine on postoperative long and short term outcome in patients with pancreatic cancer undergoing surgery. As short term endpoints: postoperative complications and resumption of bowel function. Long term endpoints include: 1 and 3 year recurrence and mortality.
