Active clinical trials for "Recurrence"

Laparoscopic incisional hernia repair a variety of fixation methods has been proposed to ensure the correct and stable intra-abdominal placement of the mesh, in order to prevent recurrence, but on the other hand avoiding long-term pain and discomfort. The optimal method is unclear. In Denmark the investigators have a nationwide database that records 80% of all ventral hernia repairs. The investigators combine data from the Danish Hernia Database, the National Patient Registry, and prospective questionnaire and clinical follow-up in order to get the true recurrence rate (clinical and reoperation rate) and the degree of long-term discomfort. Purpose The purpose of this national prospective kohort study is to compare the risk of developing recurrence of incisional hernia after laparoscopic incisional hernia repair with either absorbable or non-absorbable tacks, and to investigate possible. late complaints in terms of pain and discomfort after the two mesh fixation devices. The investigators include 355 laparoscopic incisional hernia repairs with absorbable tacks and 726 with non-absorbable tacks. It is expected that about 300 patients will be offered physical examination. Material and Method Register-based cohort study of perioperative entry of patient data and prospective questionnaire follow-up and depending on the answer to any. clinical trial. Follow-up is done by searching the Danish Hernia Database and the National Patient Register (to ensure data completeness) and distribution of patient questionnaire as reoperation for hernia recurrence is an underestimate of the true recurrence risk. Statistics There will be performed frequency analyzes and Kaplan Meyer statistics on the 2 groups supplemented with multivariate Cox regression analysis. Using non-parametric statistics. P <0.05 considered statistically significant.

The purpose of this study is to investigate if a new blood test looking at PSA and a group of PSA related proteins in a patient's blood can indicate which men after surgery with a rising PSA could benefit from treatment, and/or indicate which men are at higher risk for recurrence before initial treatment is given.

The study hypothesis is whether digestion enzyme(Combizym) and intestinal flora drugs(Bifidobacteria) can decease recurrence rate of colon polyps

Cushing syndrome refers the manifestations induced by chronic glucocorticoid excess and may arise from various causes. Iatrogenic Cushing syndrome accounts for most patients, when they are given exogenous glucocorticoid treatment. In contrast, spontaneous Cushing syndrome results from endogenous glucocorticoid over-secretion. Although Cushing disease is rare, it is the most common cause of spontaneous Cushing syndrome. The patient with Cushing disease has a pituitary corticotroph adenoma, which overproduces adrenocorticotropic hormone (ACTH). ACTH then stimulates adrenal gland to over-secret glucocorticoid. Patients with untreated Cushing disease were shown to have poor prognosis, estimated a 5-year survival rate of 50%. The first line treatment is tumor resection. Other managements include radiotherapy, medication and bilateral adrenalectomy. The initial remission rate is high (66-90%). However, some patients encounter with disease recurrence during follow-up. The aim of this study is to clarify the factors associated with the recurrence after treatment. In this study, we will review the patients with Cushing disease thoroughly and analyze associated predisposing factors. These risk factors can remind the clinical physician to early detect the recurrent disease in these patients, and further prevent morbidity and mortality in their later lives.

Clinically, recurrence and life-threatening complications are challenging problems for chronic suppurative osteomyelitis of the jaw. There is no quantitative analysis or report about the causes of or risk factors for the two problems. Doctors identify the causes or risk factors only through clinical experience. The investigators performed a retrospective study of 322 patients with chronic suppurative osteomyelitis of the jaw. The risk factors for the above mentioned two problems were analyzed by logistic regression analysis. The investigators found that some of the patients' general conditions, including age, admission temperature, admission white blood cell count, pre-admission antibiotic administration without consultation, location of the lesion, and general patient condition, were the risk factors. The results indicate that doctors should be mindful of those risk factors and that the management should be more aggressive when the above risk factors are present.

In hernia repair a mesh is used to close the defect in the abdominal wall. This mesh is either secured with tissue penetrating devices (ex. staples,tacks or sutures) or fibrin glue (Tisseel/Tissucol) or left unfixated. The investigators believe, and previous studies indicate, that the use of fibrin glue greatly reduces the amount of postoperative complications (ex. chronic pain, impaired ejaculation in men or recurrence of the hernia)when compared with the use of tacks or staples. The aim of this study is to compare the recurrence rates and amount of postoperative complications in patients who have had inguinal hernia repair with fibrin glue and in patients who have had inguinal hernia repair with tacks, staples or sutures.

Objective: To study the factors that influence the 3- year recurrence of liver carcinoma after surgery To study the related factors affecting recurrence of liver carcinoma after surgery

The objective of this study is to establish the performance characteristics of an assay that detects the recurrence of bladder cancer in patients previously diagnosed with bladder cancer. The study is conducted at locations within and outside of the United States. Testing is performed on urine specimens provided by eligible enrolled patients. Results from this study will not be used for patient management decisions.

This study evaluates the Xiaoai Jiedu Decoction in Prevention of Colorectal Adenomatous Polyp Recurrence After Colonoscopy.Half of participants will receive Xiaoai Jiedu Decoction,while the other half will receive a placebo.

Breast cancer is a major public health issue despite therapeutic advances, it is the first cause of death cancer of women in Europe. Several treatments may be proposed depending on the general condition of the patient, the characteristics of the initial tumor and the stage of the disease. The different treatments in metastatic relapse of hormone receptor-positive breast cancer are systemic treatments, such as hormone therapy, chemotherapy, targeted therapies, and possible supportive care, but also in some cases local treatments such as surgery and radiotherapy. Comparative analysis of primary mammary tumors and their metastases has demonstrated the essential role of tumor heterogeneity, both in time and space, in the progression of the disease and the occurrence of resistance to treatments. Taking into account this intratumoral heterogeneity represents a major axis of improvement in the management of patients with breast cancer. The use of innovative radiotracers such as 16α- [18F] -fluoro-17β-estradiol (FES) may allow in the future to better evaluate this tumor heterogeneity in patients with metastatic breast cancer through non-metastatic characterization. invasive different lesions. It will be possible to propose to each patient a more personalized care with possibly the administration, in addition to the systemic treatment, of a local treatment adapted to the characteristics of some secondary lesions likely to respond less well to the systemic treatment. In this pilot study, the investigators would like to estimate the number of patients and the number of metastatic sites affected by tumor heterogeneity of estrogen receptor expression, which could benefit from specific management. This study will concern a population of patients with first metastatic recurrence of hormone receptor-positive breast cancer initially, with at least one metastasis, who are candidates for treatment with hormone therapy.
