Active clinical trials for "Recurrence"

The recurrence rate of atrial fibrillation (AF) after bipolar radiofrequency ablation was about 30%. Besides the factors, left atrium diameter, the duration of AF, NT-proBNP, and ejection fraction(EF), some studies demonstrated that the specific microRNA expression (miRNA1, miRNA19,miRNA23, miRNA409 ) showed the significant change in AF patients compared with normal sinus patients, who underwent catheter ablation. Therefore, the correlation of atrial fibrillation recurrence and above-mentioned microRNA after bipolar radiofrequency ablation remained unclear, although bipolar radiofrequency ablation had high rate of sinus.

This was a prospective, single-center clinical study. The study was designed to investigate the relationship between plasma HER2 amplification or specific mutations abundance and clinical response in patients with recurrent or metastatic breast cancer.

wheezing" is defined as a musical sound caused by the passage of air through narrow respiratory tract airways . Recurrent wheeze is defined as three or more episodes of parentally reported wheeze in the past 12 months of Various risk factors are associated with recurrent wheezing and asthma: small airway caliber; decreased lung function at birth; viral respiratory infections; environmental pollution; pets; early daycare attendance; passive smoking; parental history of asthma or atopy; obesity; and socioeconomic factors.

This study aims to collect the voice output of depression patients and healthy subjects, extract the acoustic and semantic parameters, compare the similarities and differences between the depression group and the healthy control group horizontally, and track the depression patients' changes in the rehabilitation stage to construct a voice-based early warning model of depression recurrence. At the same time, the use of EEG technology, nuclear magnetic resonance and near-infrared brain imaging technology to record and analyze the neural activity characteristics behind the voice variation of depression patients, and build a neural mechanism model. And construct the facial recognition function through the convolutional neural network, extract the facial parameters to enrich the intelligent monitoring and early warning technology. Collect linguistic data of depression patients and healthy people collected in the laboratory, as well as data related to changes in the condition of depression patients in daily life and home care after treatment, and construct comparative data and dynamic observations Large database to analyze its voice mutation characteristics; Using EEG technology, nuclear magnetic resonance, and near-infrared brain imaging to record and analyze the neural activity characteristics behind the voice variation of depression patients, and build a neural mechanism model. Use the convolutional neural network to realize the facial recognition function, and extract the facial parameters to enrich the monitoring indicators. Based on the dynamic observation big data of depression speech mutation, construct the speech feature parameter vector of depression recurrence, and use adaptive personalized intelligent learning algorithm to develop intelligent monitoring and early warning technology. Establish monitoring and diagnostic indicators for recurrence early warning, verify the application of the above-mentioned intelligent monitoring and early warning technology in rehabilitation guidance, and make a comprehensive assessment.

This is a prospective randomized Phase III trial to assess efficiency of two post mastectomy hypofractionation schedules (40 Gy /15 fx / 3 weeks, 5 days per week VS 28.5 Gy delivered in 5 once-weekly fractions of 5.7 Gy each week) as adjuvant radiotherapy in female patients with breast cancer after mastectomy.

The best strategy to prevent colorectal cancer (CRC) death lies in early detection and early treatment at the local disease status of tumor. After curative resection of tumor, there are about 5~10% of stage I, 20~30% of stage II and 40~50% of stage III patients suffering metastasis during subsequent follow-up periods. Although carcinoembryonic antigen (CEA) is the most widely used biomarker for postoperative monitoring of recurrence on asymptomatic patients, it is difficult to use CEA as biological marker to identify the population with high recurrent risk in patients with early-stage cancer because lower than half of patients with early-stage cancer do not have CEA elevation. For improving the survival of patients with early-stage CRC, we need effort to search more useful biological markers to predict the risk of tumor recurrence and to select out patients with high recurrent risk to receive preventive adjuvant therapy. Circulating tumor cells (CTCs) in the blood play an essential role in cancer metastasis. Hence, the detection of CTCs and subsequent analysis can potentially revolutionize the cancer care ranging from screening, diagnosis, monitoring, to drug selection and so on. In the past decade, many methods using magnetic beads (CellSearch), filtration (RareCelletc), or flow cytometry have been developed but all of them have the shortcomings from low sensitivity, low purity, to unable to retrieve cells for downstream molecular analysis and cell culture. Recently, a biomimetic affinity based microfluidic platform has overcome abovementioned technical challenges. Importantly, by using only 2 ml of peripheral blood, Sinica's team has shown that the enumeration of CTCs increases with the CRC disease progression, where the mean CTC counts are 3, 15, 29 and 60 per ml for the stages I, II, III and IV, respectively. The results imply that monitoring CTC enumeration serially may serve as a prediction marker to identify the CRC patients with high probability of recurrence. The aims of this study are toestablishing CTC platform standard operation protocol (SOP) that leads to certification of ISO 13485 and to establish CTC criteria and evaluate its prediction power of early detection of colorectal cancer recurrence.

The main objective of this study is to assess whether a recently-developed bioassay for the molecule "secreted fibrinogen-like protein 2" (sFGL2) can be used to predict the recurrence and/or progression of Hepatitis C Virus disease in post liver transplant patients. The hypothesis is that patients with chronic HCV have higher than normal levels of sFGL2 in their blood both pre- and post-transplantation and that this will inhibit their ability to clear HCV, and influence the progression of HCV disease when it recurs.

Several studies have indicated that [124I]-PET/CT or [18F]-FDG-PET/CT may be useful to locate recurrent differentiated thyroid carcinoma lesions in patients with elevated thyroglobulin levels but who do not show pathological lesions when conventional imaging modalities are used. Thus, the investigators evaluated the effectiveness of PET/CT using both [124I] and [18F]-FDG in such patients.

This clinical trial studies the quality of life and care needs of patients with persistent or recurrent ovarian cancer, fallopian tube cancer, or peritoneal cancer. Studying quality of life in patients with cancer may help determine the effects of gynecologic cancer and may help improve the quality of life for future cancer survivors.

ET is the final stage of IVF which independently influences the treatment outcome. Successful embryo implantation is dependent on uterine receptivity. Atosiban is a novel class of drug which is effective in priming the uterus for implantation. It reduces uterine contractions and increases endomyometrial perfusion, both of which have potential benefits regarding improved IRs, CPR, and ongoing pregnancy rates. Atosiban has a good embryonic safety profile. It has no systemic toxicity, no mutagenic effects, and no carcinogenic effects
