A Prospective Study for the Assessment of Recurrence Risk in Stage II Colon Cancer Patients Using...

Colon Cancer

The aim of this study is to enroll 785 eligible stage II colon cancer patients in order to validate the performance of ColoPrint in estimating 3-year relapse rate. Secondary objectives include comparing the objective risk assessment results from the prognostic profile (ColoPrint) to both the risk assessment based on the ASCO criteria, as well as the Investigator's independent assessment. As this is the first prospective study of ColoPrint, this study will also address the logistics and quality assurance of using ColoPrint in clinical practice. Patient treatment is at the discretion of the physician, adhering to National Comprehensive Cancer Network (NCCN)-approved regimens or a recognized alternative. The enrollment period will be 6 years. It is expected that 1800 to 2400 patients will be enrolled in order to obtain 785 analysable stage II samples from eligible patients. Approximately 25-35 clinical sites will be involved worldwide. The statistical analysis will be performed by Agendia and an independent research institute or hospital. Study Design Extension Study: This will be a prospective study to measure the impact of ColoPrint on adjuvant treatment in stage 2 colorectal cancer patients. After surgery the tumor sample will be shipped in RNA Retain to Agendia. The online Clinical Report Form (CRF) 0 will be completed to document if the patient fulfils the inclusion criteria. Baseline clinical data and the patient and physician chemotherapy intention, patient's perceived recurrence risk and decisional conflict without knowing the ColoPrint result will be entered in CRF 1. After completion of CRF1 the ColoPrint result is released. CRF2 will be completed after the final treatment decision has been made. This CRF will capture the patient and physician chemotherapy intention, patient's perceived recurrence risk and decisional conflict, impact of ColoPrint and the actual treatment the patient will receive. CRF3 will be completed 12 months after enrolment and will capture the patient status, patient's perceived recurrence risk and decisional conflict. CRF4 and 5 will be completed 3 and 5 years after surgery and will capture the patient status. A sample size of 210 stage 2 colon cancer patients is required to detect a 10% overall treatment change (5% significance and 90% power). Reporting of the Results: Blinded Study; The ColoPrint results will not be reported to the physician and/or patient at the time of enrolment. All samples will be stored in a freezer until 550-575 eligible stage II patients have been enrolled. Samples will then be analyzed in one batch in a blinded fashion from the clinical results. Extension Study; The ColoPrint results will be reported to the physician and patient after CRF1 has been completed.

Genetic Mutation in Recurrent Cervical Cancer

Recurrent Cervical CancerNucleotide Variant7 more

Little is known about the characteristics of genetic mutation in recurrent cervical cancer. This study is to explore the targeted genetic mutations via a multi-gene panel, which consists of more than 500 hundred genes. The mutation characteristics are to be revealed in single nucleotide variants, copy number variations, insertion-deletion variations, and genomic structural variations. The total mutation burden (TMB) will be calculated. The status of microsatellite instability, expression of PD-1 and PD-L1 antibodies are also tested. These findings will be studies in association with the patients' prognosis and sensitivity to platinum-based chemotherapy and immunotherapy.

Coagulation/Complement Activation and Cerebral Hypoperfusion in Relapsing-remitting Multiple Sclerosis...

Multiple SclerosisRelapse

This is a multi-center, prospective, controlled study. MS patients (1° group: 30 patients in relapse; 2° group: 30 patients in remission) and age/sex-matched healthy controls (3° group: 30 subjects) will be enrolled in the study. Patients' disability level will be evaluated by EDSS and MSFC. Patients and controls will be tested for either coagulation/complement (C3, C4, C4a, C9, fibrinogen, factor VIII and X, D-dimer, protein C, protein S, antithrombin, factor II, aPTT, von-Willebrand factor), soluble markers of endothelial damage (thrombomodulin, Endothelial Protein C Receptor), antiphospholipid antibodies, lupus anticoagulant, complete blood count, viral serological assays or microRNA microarray. Patients will undergo dynamic susceptibility contrast-enhanced MRI using a 3.0-T scanner to evaluate CBF, CBV, MTT, lesion number and volume.

The Epidemiology of Recurrent Spontaneous Abortion Associated With Thrombophilla

Recurrent Pregnancy Loss

RSA is a multifactorial disorder resulting from genetic factors, anatomic factors, autoimmune disorders, endocrine dysfunction, thrombophilia, life style factors, and maternal infections. However, the underlying causes remain undetermined in up to 50% of cases. In this clinical cohort study, we intended to get an epidemiological evidence for patients with recurrent spontaneous abortion associated with thrombophilla.

Neural Indices Associated With Relapse in Cannabis Dependence

Cannabis Dependence

The aim of this fMRI study is to investigate neural indices of relapse in cannabis dependence. The development and maintenance of drug addictions have been associated with deficits in cognitive control, craving and impaired stress regulation. Therefore, neural markers of brain processes underlying the beforementioned components will be studied. Subsequent follow-up drug use interviews will reveal associations between relapse in cannabis dependence and alterations in brain networks of cognitive control, craving and stress.

Review of Complex Recurrent Hernia Repair

Recurrent Hernia

Abdominal wall incisional hernia is a common finding in patients who have undergone previous intra-abdominal surgeries. Common methods of abdominal fascial closure include primary closure, mesh inlay versus onlay, with or without component separation. All these methods have been shown to have recurrence rates for hernia between 3%-60% in the literature. The study describes the investigators innovative and preferred method for reconstruction of the abdominal wall as BARS (bony anchoring reinforcement system). This method manages the abdominal fascial integrity to reduce the recurrence of incisional hernia while providing an aesthetically superior abdominal wall contour.

Early Postoperative Recurrence in Crohn's Disease: Predictors of Research Targeting the Constitutional...

Flammatory Bowel DiseaseCrohn's Disease

Crohn's disease is a disease of complex etiology, multifactorial and still poorly understood. This disease, due to its morbidity and mortality, poses a significant public health problem in France. Apart from the involvement of bacterial factors and those involving the permeability of the epithelial barrier, it is now well recognized that several factors are associated with genetic predisposition in some of these patients. Among these factors, the Nod2 mutations were first identified. Studies concerning the presence of these mutations and the severity of disease results were sometimes conflicting. Very recently, new interesting mutations in genes involved in autophagy were found with greater frequency in patients with Crohn's disease. These mutations observed in Atg16 and IRGM genes. It has been particularly shown on large patient cohorts,the IRGM polymorphism was associated with a progressive disease, with histological severity scores. One of the severity criteria of Crohn's disease is the early recurrence observed in some patients after surgical resection of the injured segment. Predictive factors for such recurrence after surgery are not known or not.

Effects of Chemotherapy on Circulating Tumor Cells and Recurrences in Cervical Cancer Patients

Cervical Cancer

Cervical cancer is a major health problem for Chinese women. It is estimated that nearly 100,000 new cervical cancer cases occur in China every year, which accounts for about 20 percent of global new cases. Surgery and radiotherapy are two major radical treatment methods for IB-IIB cervical cancer. Unlike the United States and some other countries, most of operable women with IB-IIB cervical cancer received radical surgery other than radiotherapy in China. Patients with recurrence risk factors (lymph node metastasis, deep stromal invasion, positive lymphatic vascular space, et al. ) also received adjuvant therapy after surgery, such as radiotherapy or chemoradiotherapy that are recommended in the NCCN guidelines. However, in China a substantial part of patients especially those admitted to tertiary hospitals received several courses of chemotherapy instead of radiotherapy if they had recurrence risk factors . In our previous study, we found that patients with intermediate risk factors (deep stromal invasion, positive lymphatic vascular space, bulky tumor>4cm) had better disease-free survival and recurrence-free survival when they received chemotherapy compared with radiotherapy. The objective in this study is to investigate whether the advantage of postoperative chemotherapy is a result of circulating tumor cells (CTC) in some of the patients with intermediate risk factors.
