Active clinical trials for "Recurrence"

The purpose of this multicenter study is to assess a diagnostic strategy concerning differential diagnosis between radiation necrosis and relapse in brain metastases treated with radiosurgery. Two non-invasive tests - positron emission tomography (PET) with 1F-fluoro-ethyl-tyrosine (FET) and magnetic resonance spectroscopy (MRS) - will be compared to histology in a cohort of patients presenting growing lesions 6 months after radiosurgical treatment. The results of this study should help to earlier diagnosis of recurrences after radiosurgery and to perform an appropriate treatment for patients.

Traditional Chinese Medicine (TCM) could be used to treat Recurrent urinary tract infection (RUTI).

This pilot clinical trial studies positron emission tomography (PET)-magnetic resonance imaging (MRI) and PET-computed tomography (CT) as diagnostic imaging in patients with colon and/or rectal cancer. New diagnostic imaging procedures, such as PET-MRI, may help find and diagnose rectal cancer or recurrence of colorectal cancer

The purpose of the study is to evaluate the mechanisms of recurrent atrial fibrillation after cryoballoon ablation using the Arctic Front Ablation System. For those with pulmonary vein reconnection, specific sites of reconnection will be evaluated with left atrial intracardiac echo (ICE) guidance. The Achieve mapping catheter will be evaluated head-to-head with our current method of ICE-guided recordings from a conventional mapping catheter with high output pulmonary venous pacing.

Evaluate the impact of hybrid 18F-Fluoro-choline (18F-FCH) PET/MRI imaging on the clinical management of men with suspected recurrent prostate cancer post prostatectomy or radiotherapy. We hypothesize that hybrid imaging incorporating 18F-FCH PET/MRI imaging will be feasible and will lead to changes in management decisions among men being re-staged for suspected prostate cancer recurrence post-surgery or radiation who are potentially eligible for local salvage therapy.

Recurrent respiratory papillomatosis in children caused by HPV 6,11 can be a life threatening condition resulting in surgical interventions. The maturing and disintegrating papillomas are the sources for the subsequent HPV relapses and immunization might slow down or even prevent this ongoing process. After an initial immunological and ear-nose-throat (ENT) assessment children with at least 3 relapses in their patient history will be vaccinated with 4-valent HPV vaccine according to the following schedule: 0., 2., 6. months. It will be followed by an immunological and 3 ENT examinations to assess response to vaccination.

The purpose of this study is to verify the superiority of NIK-333 (Peretinoin) to placebo in inhibiting the recurrence of HCV-positive HCC in patients showing complete cure of the disease, with the recurrence-free survival as the primary endpoint, in a multi-center, randomized, double-blind, placebo-controlled, parallel-group comparison study.

The purpose of this study is to test different ways to help cancer patients maintain their smoking abstinence. Participants may receive educational materials as part of the study.

Depression treatments including physical activity and sleep management has been shown to relieve depressive symptoms among participants suffering depressive episodes. This study evaluates the potential of these methods as prevention of depressive relapse or recurrence

This study examines performing pilonidal sinus surgery minimal invasively with videoendoscopic approach.
