Active clinical trials for "Recurrence"

PSA-recurrence prostate carcinoma is associated with two general problems. Localisation of PSA-recurrence is unconfident. In many cases it's not clear if a local, locoregional oder systemic relapse is available. There is no standard therapy proved by randomised clinical trials. Recommended radiotherapy starting with PSA-value < 0.5 ng/ml according to german S3 guidelines is based on retrospective data. These difficulties may lead to a therapy potentially not adapted to patients situation of disease.This study aims to randomised examine if an instant radiotherapy of prostate PSA-recurrence (PSA-value between 0.2 - 0.99 ng/ml) or a delayed radiotherapy with additional imaging (PSA value >= 1 ng/ml) including PET/CT and bone scintigraphy for reliable information about tumor location and expansion is beneficial regarding therapy efficiency, quality of life and social economic aspects.

Background- Idiopathic Nephrotic syndrome is the common glomerular disease in childhood. conventional treatment is steroid treatment and nearly 90% response to this treatment well. Response to this treatment is the most important prognostic factor and this patients has a benign disease course. 60-70% among patients that response to steroid treatment,will suffer a relapse of NS.repeated steroids courses can lead to serious adverse events in children such as low bone density,weight gain ,growth slow down ,elevated blood pressure and eye pressure.there is side effect corelation between steroid dose and treatment duration. guidelines for steroid dose for NS relapse are not based on retrospective clinical research but only on Nephrologists and experts opinion. Rational- What would be the optimal low dose steroids and the shortest time of treatment in Nephrotic syndrome relapse?

Catheter ablation of persistent atrial fibrillation (AF) remains a challenging procedure. Even in experienced centres, repeat interventions are necessary in up to 70 of patients to achieve sinus rhythm at a long-term follow-up. While there is a consensus to perform pulmonary vein isolation (PVI) as a cornerstone for the ablation of paroxysmal and persistent AF ablation, different additional ablation strategies are used to achieve a modification of the substrate that perpetuates the arrhythmia: linear lesions (anterior and roof lines) or ablation of complex fractionated atrial electrograms (CFAE). In the stepwise approach PVI, CFAE ablation and/or LL are combined according to the presenting arrhythmia during procedure. The aim of the study is to determine whether there is a difference in terms of freedom from arrhythmia between a stepwise approach and a linear ablation for repeat procedure in patient with recurrence of persistent atrial fibrillation.

Endometrial cancer (EC) is the 8th most common female cancer in Taiwan. Its incidence is increasing in the recent few years, around 1,200 new cases per year. The outcome of recurrent EC is disappointing, except focal recurrences that could be irradiated or removed. Chemotherapy is currently the most common salvage treatment for recurrent endometrial cancer. However, the response rate (RR) to 2nd-line treatment is approximately 0-27.3%, with short median time to progression, 2-3.9 months and low overall survival, 6.4-11 months. Due to progress of studies on the molecular and genetic basis of cancer and cellular signaling pathways, targeted therapy has been developed for various cancer treatments. A Gynecologic Oncology Group study found 44% of advanced endometrial cancer had HER>=2+ and the ratio of HER2:chromosome 17 (CEP17) >=2. Another study showed that HER>=2+ was seen in 47% of carcinosarcoma. These evidences indicated HER2 gene amplification and HER2 overexpression occur in endometrial cancer and carcinosarcoma, especially in those of high grade and recurrence. Lapatinib (L), an oral inhibitor of both EGFR(epidermal growth factor receptor) and HER2(human epidermal growth receptor), has been shown to be an effective treatment in HER2/neu overexpressing metastatic breast cancer. Ixabepilone is a semisynthetic analog of the natural product epothilone B, and recently has been approved by US Food and Drug Administration as a treatment option in metastatic breast cancer. It was also observed that lapatinib + ixabepilone killed more breast tumor cells than trastuzumab + paclitaxel in vitro. Two GOG(Gynecologic Oncology Group) studies had reported that weekly Ixabepilone as 2nd-line chemotherapy provided a similar RR to 3-weekly regimen of 14.3% in platinum- and taxane-resistant epithelial ovarian cancer with less severe toxicities. The combination of lapatinib and ixabepilone is expected to become an effective treatment for recurrent endometrial cancer and carcinosarcoma, but the ideal dose is yet to be surveyed.

Clinical trial to compare safety and effectiveness of 10-week supplementation with Trenev Trio®/Healthy Trinity® vs. placebo in otherwise healthy subjects with recurrent gastrointestinal symptoms.

A randomized phase II tials to study whether it's benefit of adding Nimotuzumab to chemoradiation for patients with esophageal squamous cell carcinoma after radical esophagectomy who suffer with locoregional lymph nodes recurrence.

Current planning for studies involving patients with recurrent, persistent, or metastasized cervical cancer must take into consideration that up to 75% of all patients are assumed to have already been treated with cisplatin in conjunction with radiation therapy. It seems questionable to continue to treat patients with cisplatin when cancer has recurred. Thus, it is important to seek alternative active combinations. The studies GOG 169 and 179 demonstrated that a combination of paclitaxel and cisplatin was superior to a cisplatin monotherapy with respect to therapeutic response and progression-free survival, as was a combination of topotecan and cisplatin with respect to therapeutic response, progression-free survival, and total survival. To achieve further improvement in total survival and to answer questions regarding the value of using a platinum-free combination, we propose that a study should be conducted to compare the efficacy of a platinum-free combination of paclitaxel and topotecan to a combination of cisplatin and topotecan.

Determination of response rate Assessment of toxicity and determination of "time to progression"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. R-flurbiprofen may be effective in delaying the recurrence of localized prostate cancer. PURPOSE: Randomized phase II trial to study the effectiveness of R-flurbiprofen in treating patients who have localized prostate cancer at risk of recurrence following radiation therapy and/or prostatectomy.
