Active clinical trials for "Recurrence"

This study is designed as a multi-center, randomized, double-blind, placebo-controlled trial. Subjects in the intervention group will be treated with XLJDOD compound granule. Subjects in the control group will be treated with placebo (XLJDOD mimetic agent).

This phase II trial evaluates Fluorine-18 radiohybrid prostate-specific membrane antigen (18F- rhPSMA)-7.3 positron emission tomography (PET)/computed tomography (CT) scans with and without furosemide for the reduction of bladder activity in patients with prostate cancer that has come back (recurrent) based on elevated levels of prostate-specific antigen (PSA) in the blood (biochemical) after prostate surgery (prostatectomy). Furosemide is a diuretic substance that increases the urine flow into the bladder, thereby decreasing the level of radioactivity within the bladder, which may help to see any abnormal areas that could be masked by the radioactivity within the bladder. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, rhPSMA ligand. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Adding furosemide to 18F-rhPSMA 7.3 PET/CT scans may help to better detect and treat patients with biochemically recurrent prostate cancer.

To prospectively evaluate the radiodrug biodistribution of a novel PET imaging agent [68Ga]Ga-PSMA-D5 in different organs of prostate cancer patients and its diagnostic efficacy in the diagnosis, recurrence and metastasis of prostate cancer, and to compare with [68Ga]Ga-PSMA-11.

This is a prospective, single-center, single-arm phase 2 study in patients with clear cell renal cell carcinoma and metastasis or recurrence suspicion. The goal is to determine the sensitivity and specificity of 68Ga-NY104 PET/CT in patients with clear cell renal cell carcinoma and metastasis or recurrence suspicion

Low Back Pain is a common heath condition with high rates of recurrence and huge associated costs. Research has focused its efforts on analysing the effects of interventions while knowledge about effective secondary prevention strategies is limited. MyBack study aims to analyse the effectiveness of a tailored exercise and behavioural change program (MyBack program) in the secondary prevention of low back pain, and evaluate acceptability, feasibility and determinants of implementation by the different stakeholders, as well as the implementation strategy of the MyBack program, through a hybrid type I, randomized, controlled and multicentre study of effectiveness and implementation in the context of primary health care.

This is a prospective, open-label, single-arm, multicenter bridging study in Chinese patients with prostate cancer. This multicenter study is planned to be conducted in patients with biochemical recurrence (BCR) of elevated PSA after radical prostatectomy or radical radiotherapy. This study investigates how well 68Ga-PSMA-11 PET/CT works in detecting BCR prostate cancer in Chinese patient. 68Ga-PSMA-11, developed by Telix, is a new molecular entity tracer with the trade name Illuccix®, which is approved by FDA for the examination of: 1) patients with suspected metastatic PC who are scheduled for initial treatment; 2) patients with biochemical recurrence of elevated PSA levels after initial radical radiotherapy.

Due to rising antibiotic resistance, there has been a focus on non-antibiotic prophylactic measures for postmenopausal patients with recurrent urinary tract infections (rUTI), one of which is the safe and efficacious option of vaginal estrogen therapy. Standard application of vaginal estrogen cream entails intravaginal application of the cream twice a week, but some providers counsel patients with rUTI to apply a small, pea-sized amount to the periurethral area. This ideally reduces the amount of vaginal estrogen used while attaining a similar effect. However, to date, there is no data to prove that the periurethral technique of application is similar or non-inferior to intravaginal application in preventing UTI.

Paraesophageal hernia causes pain, heartburn, regurgitation, anemia and in extreme, life-threatening strangulation. For symptomatic patients, laparoscopic surgery is offered which includes hiatal defect closure and antireflux surgery. However, recurrence rates are high between 12 and 42%. In order to reduce recurrences, mesh has been used with various materials and techniques with conflicting results. Non-absorbable mesh has been linked with adverse events including erosion of esophageal wall. Traditionally used biological mesh materials are expensive and therefore problematic in routine use. Use of polyglactin (Vicryl®) mesh, which degrades in 6-8 week, has been reported in paraesophageal hernia surgery. Previously, no randomized controlled trial comparing sutures only and polyglactin mesh has been performed. In this trial, the aim was to randomize total of 110 patients to receive sutures only or mesh repair. Primary outcome was recurrence of paraesophageal hernia at 6 months after the repair based on computed tomography scan. Secondary outcomes included symptomatic recurrences, reoperation rate, quality of life, reoperations up to 20-years after surgery and use of proton pump inhibitors up to 20-years after surgery.

Esophageal cancer is a highly lethal disease, and its incidence is still increasing in the world. Recent advances in image-enhanced techniques such as Lugol chromoendoscopy and narrow band imaging, the number of patients with early esophageal squamous cell neoplasias (ESCNs) detected has markedly increased. Endoscopic submucosal dissection (ESD) enables en bloc resection of the neoplasia, and the resected specimen allows for a pathological assessment to evaluate the curability. However, the patients who received complete ESD for early ESCNs frequently developed metachronous recurrence. The cumulative metachronous recurrence rate at 5 years was 50%, and the mean annual incidence of newly diagnosed metachronous tumors was 10%. Among them, those with "speckled" lugol staining pattern over the esophageal background mucosa have the highest risk and should be seen as a precancerous lesion of ESCCs. This issue is gaining attention in the era of endoscopic treatment, but currently there was no appropriate strategy to prevent the tumor recurrence in these high-risk subjects. Endoscopic radiofrequency ablation (RFA) is a rapidly evolving therapeutic modality, and recent studies have shown its efficacy and safety for eradicating for flat type early ESCNs. To search a best strategy for the prevention of ESCNs, the investigators thus propose a hypothesis that the preemptive RFA for esophageal "speckled" lugol background mucosa may prevent the metachronous neoplastic recurrence after complete endoscopic resection.

The present study aims to assess the effectiveness of three different retention schemes used to maintain tooth position after orthodontic treatment with fixed orthodontic appliances (stability) and to evaluate possible association between retention scheme and gingival recessions on the lingual surfaces of the lower anterior teeth seen for up to 5 years post-treatment. Moreover the possible association between primary relapse tendency and long term occlusal stability will be evaluated.
