Filter by:The investigators compare the recurrence rate difference between two years after transurethral resection of the bladder tumor according to the method of anesthesia. Anesthetic methods are general anesthesia and spinal anesthesia. Assessment of recurrence is assessed by bladder endoscopy, CT, and pathological examination of surgical specimens.
Advanced laryngeal squamous cell carcinoma (SCC) remains a highly morbid and fatal disease despite aggressive interventions. Mortality is high in this cohort: laryngeal cancer affects over 13 000 patients in the United States, with over 3500 deaths annually.The results of the Veterans Affairs Cooperative Studies Program Laryngeal Cancer Trial and subsequent studies demonstrated similar overall survival (OS) rates for organ preservation protocols involving radiotherapy (RT) or chemoradiotherapy (CRT) when compared to surgery, with the benefit of preserving the larynx in a large majority of patients. As such, the use of RT or CRT has become the predominant initial intervention for patients with laryngeal SCC.6 However, the prognosis of recurrent and persistent laryngeal SCC is particularly dire.In this study, we sought to identify preoperative predictors of survival for patients with recurrent or persistent laryngeal SCC in order to set patient expectations and address modifiable risk factors. Identification of predictors of survival may also identify patients who could benefit from novel therapeutic agents in a neo/adjuvant fashion. Herein,we examine a cohort of patients with recurrent or persistent laryngeal SCC after definitive RT/CRT who has undergone total laryngectomy in order to identify potential preoperative predictors of clinical outcomes.
The present study has been developed with multiple aims: 1) to refine available models for liver transplantation which would be able to cover the fate of HCC candidates from an ITT point of view; 2) to develop such an approach on cohorts coming from both Eastern and Western countries; 3) to maintain simplicity of use; 4) to provide individual prognostication taking into account different causes of death, through a competing-risk model; 5) to provide an external validation on cohorts coming from both Eastern and Western countries. All these aims converge at providing a comprehensive and useful assessment suitable for both candidates selection and allocation priority.
Atrial fibrillation is the most common arrhythmia in clinic. It can lead to heart failure or stroke, and has a high disability rate and mortality rate. At present, although radiofrequency ablation can cure atrial fibrillation, the success rate is only 50~70%, and has a high recurrence rate. In recent decades, no effective new antiarrhythmic drugs have been introduced, but there are side effects in long-term application of the existing antiarrhythmic drugs. Therefore, it is urgent to provide new and effective antiarrhythmic drugs. Autophagy level of atrial myocytes in atrial fibrillation patients was significantly higher than that in sinus rhythm. Hydrochloroquine (HCQ) is a hydroxychloroquine sulfate composed of 4- amino quinoline compounds. As an effective inhibitor for autophagy, HCQ could effectively prevent the increased autophagy level of atrial myocytes in atrial fibrillation rabbits, prevent atrial effective refractory period (AERP) shortening, and decrease the rate and duration of atrial fibrillation. At present, hydroxychloroquine is mainly used in the treatment of rheumatic immune system diseases and anti malaria. Because of its good safety and small side effects, HCQ has become an indispensable member of drugs in the combined treatment of rheumatoid arthritis and systemic lupus erythematosus patients. In recent years, studies have reported that hydroxychloroquine plays an important role in the prevention and treatment of cardiovascular diseases. Chloroquine could effectively shorten the action potential of atrial myocytes by blocking the inward rectifier potassium ion channel (Kir2.1) and reducing the inward potassium ion current Ik1. HCQ could also reduce 72% (P=0.002), and 70% for the risk of coronary heart disease, stroke, and transient ischemic disease. So the investigators speculate that HCQ may be a potential drug to block the occurrence of acute atrial fibrillation.
The two main mechanisms for atrial fibrillation (AF) recurrence after cryoablation include Pulmonary vein (PV) reconnection and the presence of non-PV associated arrhythmic focuses. The aim of this study is to investigate the prevalence of each mechanism and if biomarkers may be used to predict of these events. Eighty patients with paroxysmal or persistent AF will undergo PV isolation with cryoablation followed by loop recorder implantation. Patients in whom atrial tachyarrhythmias recur during 12 months follow-up (outside of the 3-month post procedure blanking window) will be offered a second electrophysiology study (EP) study to assess PV isolation and non-PV focuses and further ablation performed as required. At baseline blood samples will be taken to investigate the correlation between specific biomarkers and both the incidence and type of recurrence. The correlation between recurrence of atrial tachyarrhythmias due to non-PV associated arrhythmic focuses and elevated baseline levels of NT-ProBNP, CRP, TNF, MMP1 will be pre-specified. 40 consecutive patients will have a biopsy taken from the intraventricular and interatrial septum to investigate the correlation between myocardial inflammation, the presence of fibrosis and recurrence of atrial tachyarrhythmias. Correlation between biomarkers of inflammation and biopsy-proven myocardial inflammation or fibrosis will be assessed.
This phase Ib trial studies the best dose and side effects of niraparib and copanlisib in treating patients with endometrial, ovarian, primary peritoneal, or fallopian tube cancer that has come back. Niraparib and copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to explore the efficacy of Norflo Oro in the treatment of relapsing autoimmune uveitis (RAU), measured as a long term reduction of the frequency and the severity of relapses, in patients with HLA-B27 associated uveitis, under conditions of routine medical practice. The reduction of the mean number of relapses per patient between the year before study treatment and the study period will also be assessed.
This is a Phase II, multicenter, open-label, randomized study to compare the efficacy of venetoclax in combination with fulvestrant compared with fulvestrant alone in women with ER+, HER2-negative, locally advanced or Metastatic Breast Cancer (MBC) who experienced disease recurrence or progression during or after treatment with CDK4/6i therapy for at least 8 weeks. As of 9th October 2020, participants in the Venetoclax + Fulvestrant arm, have all discontinued Venetoclax treatment and have continued on Fulvestrant treatment alone.
This phase III trial studies how well mitotane alone works compared to mitotane with cisplatin and etoposide when given after surgery in treating patients with adrenocortical cancer that has a high risk of coming back (recurrence). Cortisol can cause the growth of adrenocortical tumor cells. Antihormone therapy, such as mitotane, may lessen the amount of cortisol made by the body. Drugs used in chemotherapy, such as cisplatin and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether mitotane alone or mitotane with cisplatin and etoposide after surgery works better in treating patients with adrenocortical carcinoma.
This study is to compare radiation toxicity of accelerated partial breast irradiation (ABPI) with whole breast irradiation (WBI) in low-risk breast cancer.
