Active clinical trials for "Recurrence"

The study evaluates whether there is a reduction in the rate of postoperative progression of the disease following extensive mesenteric excision (EME), when compared to that of limited mesenteric excision (LME), in patients undergoing ileocolic resection for Crohn's disease. Half of participants will receive EME, while the other half will receive LME.

Patients with a biochemical recurrence after radical prostatectomy for moderate- or high- risk prostate cancer are randomly assigned to hypofractionated, accelerated high dose radiation therapy group (65 Gy, 26 fractions) and a control group of standard treatment group (66 Gy, 33 fractions). The criteria for stratification at randomization include 1) risk groups, 2) androgen deprivation therapy, and 3) PSA before salvage radiation therapy, which affect biochemical recurrence. It is expected that hypofractionated, accelerated high dose radiation therapy will have a superiority in terms of biochemical control to conventional radiation therapy, and the present study would like to confirm this. In addition, we aimed to evaluate and compare the toxicity and quality of life index of two radiation therapy regimens.

The aim of the study is to evaluate different ablation strategies in patients with AF recurrences despite chronic PVI after prior catheter ablation. The present study is a multi-centre prospective randomized study enrolling 256 patients with drug-refractory AF despite previous AF ablation. After PV remapping confirming durable PVI patients will be assigned to 2 different groups: Group A: Substrate modification. After obtaining a voltage map of the LA, substrate modification will be performed aiming at low-voltage areas (LVA) < 0.5mV. Group B: LAA isolation. Patients will undergo LAA-isolation using the cryoballoon (CB). Catheter ablation procedures will be performed with commercially available devices including 3D mapping systems (CARTO, EnSite) and irrigated radiofrequency current (RFC) ablation or cryothermal balloon ablation (Arctic Front Advance). The primary endpoint is freedom from documented recurrence of AF or any atrial tachyarrhythmia lasting > 30 seconds between day 91 and 365 after the index procedure.

Recurrence is a common problem after catheter ablation for atrial fibrillation, affecting at least one out of three patients. Inflammation due to the procedure may contribute to pulmonary vein reconnection and, thus, failure of catheter ablation. This pilot study will assess whether a randomized, placebo-controlled, double-blind trial investigating a 10-day treatment with colchicine, a potent anti-inflammatory drug, to improve patient relevant outcomes after catheter ablation for atrial fibrillation is feasible.

This study is aimed to evaluate difference of the 2 year recurrence free survival after pancreaticoduodenectomy for pancreatic cancer between artery-first approach and conventional procedure groups.

The purpose of this study is to collect preliminary data on the feasibility and acceptability of the randomization of two relapse-prevention treatment conditions after discharge from intensive eating disorder (ED) treatment: an imaginal exposure therapy and a writing and thinking intervention. The second aim to test for (a) differences between the two treatments for the prevention of relapse and (b) preliminary change on clinical ED outcomes (e.g., ED symptoms, fears). The investigators further aim to examine the two treatments target fear extinction and if fear extinction is associated with ED outcomes. The investigators also plan to test if baseline differences in fear conditioning relate to change in ED outcomes across treatment.

Study design: A prospective phase II, non-randomized observational study of dose-escalated pencil beam proton therapy re-irradiation for pelvic recurrences from rectal cancer. Re-irradiation is either a part of neo-adjuvant treatment or as a definitive treatment strategy for un-resectable recurrences.

We are trying to determine if Clotrimazole vaginal tablets with oral Lactobacillus is better than Clotrimazole vaginal tablets in Preventing the Recurrence of vulvovaginalcandidiasis

Study to assess venetoclax + azacitidine and donor lymphocyte infusion (DLI) in patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) with blasts < 30% in relapse after allohematopoietic stem cell transplantation (AHSCT).

This study aims at exploring whether plasma radiofrequency ablation at low temperature is associated with better survival outcome in localized recurrent nasopharyngeal carcinoma by conducting a randomized controlled trial of plasma radiofrequency ablation at low temperature versus electrocautery block resection at high frequency for localized recurrent nasopharyngeal carcinoma. If the hypothesis is confirmed, it is expected to provide a convenient choice for the surgical treatment of localized recurrent nasopharyngeal carcinoma.
