Active clinical trials for "Recurrence"

Pathologic complete response (pCR) after multimodal treatment for locally advanced rectal cancer (LARC) patients is considered as the gold-standard of treatment success as it is associated to privileged oncologic outcome. Nevertheless, data from multicenter high-volume cohorts with long term follow-up are scarce. This is a multicenter observational study using prospectively collected data from the Spanish Rectal Cancer Project database. The main objective of the study is to update long-term oncologic follow-up of those patients treated for LARC with nCRT and surgery (either TME or subtotal TME; S-TME) who had obtained a pCR. Secondary objective is to analyze demographic, clinical, operative and treatment variables in search of related factors to adverse oncologic outcomes, like distant recurrence or tumor-related deaths. The results are reported in accordance with the STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) Statement for observational studies. All calculations are performed using Stata 13.1 (StataCorp, Texas, USA).

There are currently no standard criteria for evaluating the risk of recurrent disk herniation following surgical repair. This study investigated the predictive values of five presurgical imaging parameters, paraspinal muscle quality, annular tear size, Modic changes, modified Pfirrmann's disc degeneration grade, and presence of sacralization or fusion. Clinical status and MRI findings were evaluated before surgery and 4, 12, and 24 months post-surgery using a Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Short Form 36 (SF36).

Purpose: This study aims to investigate the demonstrability of increased inflammation and neurodegeneration in multiple sclerosis (MS) patients in relapse period compared to MS patients in remission by cross-sectional analysis of in-vivo corneal confocal microscopy (IVCM), and to evaluate the alternations with a second IVCM administered at least 6 months after the relapse period. Methods: This prospective, non-randomized-controlled, cross-sectional study included 58 MS patients which were grouped regarding the presence of relapse (MS-Relapse group [n=27] and MS-Control group [n=31]), and age-sex matched 30 healthy controls (HC). The corneal nerve fiber density (CNFD), the corneal nerve branch density (CNBD), the corneal nerve fiber length (CNFL), and dendritic cell (DC) density were evaluated in all MS patients and HCs by IVCM. If the patients in the MS-relapse group did not have an attack within 6 months, the same parameters were evaluated with the second IVCM. The patients with a history of optic neuritis or trigeminal symptoms were excluded.

Background. Limberg flap, one of the recently being popularized off-midline closure techniques, is widely performed for the treatment of sacrococcygeal pilonidal sinus; however, recurrences still can be seen. Objective. The aim of this study was to assess the relationship between recurrence and off-midline closure errors made in Limberg flap reconstructions. Design. A multicenter, matched-case-control study was conducted in three participating centers in Turkey. Settings. Each hospital's database was searched separately and all patients with and without recurrence who underwent LF surgery for primary SPS from January 2008 to July 2015 were identified. Patients. Sixty patients with recurrent disease (recurrent group, RG) and 120 matched cases of recurrence-free patients for at least 5 years following surgery (non-recurrent group, NRG) were included to the study. Interventions Main outcome measures. According to the off-midline closure concept, LF reconstructions were classified into incorrect closures (Type 1, 2 and 3) and correct closures (type 4, 5 and 6). Then the two groups were analyzed.

The investigators will examine if pregnancy increases risk of ventral hernia recurrence

SCARWARS study deals with the first on-human evaluation of a compressive device dedicated to the prevention of keloïd scars recurrence after surgery. The tested device is made with clinical grade silicon. SCARWARS is a monocentric study. 27 patients will be include and follow during one year. The primary outcome of this study is the number of keloid recurrence after treatment.

Nearly three-quarters of patients with Crohn's disease have small bowel involvement and 80% of them will have complications that will require a surgical procedure, usually an ileocolonic resection with ileocolonic anastomosis. The rate of recurrence at the anastomosis site and in the ileum after surgery, whether symptomatic or not, is high, at least 60% in one year and 80% within three years. The gold standard for monitoring being ileocolonoscopy, endoscopic surveillance is recommended in these patients, once between 6 to 12 months after surgery and then every 2 years. The MRI enterography is a validated technique for the assessment of small bowel Crohn's disease. The enterography MRI is a validated technique for the assessment of small bowel Crohn's disease. The MRI enteroclysis was evaluated in two studies compared to endoscopy, with excellent performance in terms of recurrence detection sensitivity and suggested as an alternative to it to avoid an invasive procedure repeated in these patients. The MRI enterography (without enteroclysis) does not provide as good distension of the bowel loops as MRI enteroclysis because it relies on the principle of oral ingestion prior to the examination of large amounts of liquid. However, it is much better tolerated by the patient, does not involve radiation that exists with enteroclysis, is much simpler to use and requires no special equipment to magnetic fields.

This is a nested multicenter, prospective cohort study within the I-SPY 2 TRIAL for women undergoing neoadjuvant chemotherapy for primary breast cancer who are also undergoing definitive surgical resection and have clinical or radiographic evidence of residual tumor at the completion of chemotherapy.

Influence of histological concordance on the risk of recurrence: the histological concordance being the comparison between the biopsies and the endoscopic resection piece and its concordant response rate.

Miscarriage affects one in five pregnancies and little progress has been made in understanding and treating this distressing condition. C. trachomatis is the most common sexually transmitted infection in the UK. C. trachomatis infection can have serious health consequences, including fallopian tube damage. Untreated C. trachomatis infection and tubal damage have been associated with miscarriage and adverse pregnancy outcomes such as preterm birth, low birth weight and stillbirth. A cohort study is needed to establish the prevalence of tubal disease in women with recurrent miscarriages. HyCoSy will be performed to identify tubal disease and establish the magnitude of the problem in the recurrent miscarriage population. The prognosis of tubal disease on miscarriage and other obstetric outcomes, and the role of medical interventions such as tubal surgery (to treat hydrosalpinx) on reducing miscarriage and adverse obstetric outcomes will also be studied. Objectives Establish the prevalence of hydrosalpinx in the recurrent miscarriage population. Establish the prognosis of women diagnosed with recurrent miscarriage with concurrent hydrosalpinx. Explore the role of tubal surgery for improving reproductive outcomes in women with recurrent miscarriage population and hydrosalpinx.
