Active clinical trials for "Neoplasms"

This research study aims to investigate changes inside kidney cancers (also known as Renal Cell Carcinoma or RCC), and in normal kidney surrounding the tumour, when patients are treated with systemic therapy. Samples, radiological images and data from a previous trial (NeoSUN) will be analysed and/or reanalysed, in accordance with the consent of NeoSUN participants.

intramedullary astrocytoma is a rare and devastating spinal cord glioma. while the management of intracranial astrocytoma includes gross total resection, radiotherapy and chemotherapy, spinal cord astrocytoma is very difficult to be totally removed due to its infiltrative nature and unclear plane of dissection; Moreover, the use radiotherapy and chemotherapy for spinal cord astrocytoma is controversial. Therefore, the treatment for spinal cord astrocytoma is very limited as compared to its intracranial counterpart. Inadequate understanding of spinal cord astrocytoma mainly contribute to limited treatment, while the molecular profiling of intracranial astrocytoma is relatively well understood. Hence, we performed whole-exome sequencing of intramedullary astrocytoma aiming to identify the pathophysiological mechanisms underlying spinal cord astrocytoma

A prospective multicenter observational cost-utility study following older or high-risk patients with colorectal cancer with and without prehabilitation before surgery.

It is proposed to undertake a study to determine the diagnostic utility of using RCM for the diagnosis of Basal Cell Carcinoma (BCC) in a tertiary referral centre as outlined by the recent NICE report (Nov 2015). This will allow an assessment of the potential to avoid diagnostic biopsy within the treatment pathway.

Rationale: For locally advanced esophageal cancer the standard treatment consists of 5 weeks of neoadjuvant chemoradiotherapy (nCRT) followed by surgery. Surgery is currently performed independent of the response to nCRT and is associated with substantial morbidity. Prior knowledge of the eventual response to nCRT would greatly impact on the optimal care for many esophageal cancer patients for two imperative reasons: Firstly, it is argued that patients who achieved a pathologic complete response (pCR, 29%) may not have benefitted from surgery. Consequently, proper identification of pathological complete responders prior to surgery could yield an organ-preserving regimen avoiding unnecessary toxicity. Secondly, non-responders are exposed to the side effects of nCRT without showing any tumor regression. Early identification of the non-responders during nCRT would be beneficial for this group as ineffective therapy could be stopped, and for who altered treatment strategies could be explored. Objective: To develop a multimodal model that predicts the probability of pathologic complete response to nCRT in esophageal cancer, by integrating diffusion weighted magnetic resonance imaging (DW-MRI) and dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in conjunction with combined 18F-fluorodeoxyglucose positron emission tomography and computed tomography (18F-FDG PET-CT) scans acquired prior to, during and after administration of nCRT. Study design: Multi-center observational study Study population: Patients (>18 years) with potentially resectable locally advanced squamous cell- or adenocarcinoma of the esophagus or gastroesophageal junction, receiving nCRT prior to surgery. Intervention: In addition to the standard diagnostic work-up for esophageal cancer that includes a 18F-FDG PET-CT scan at diagnosis and after nCRT, one 18F-FDG PET-CT scans will be performed during nCRT, as well as three MRI scans (before, during and after nCRT) within fixed time intervals. Furthermore, after response imaging after nCRT has been performed, but prior to surgery, patients will undergo (on an opt-out basis) an endoscopy and/or endoscopic ultrasonography (EUS) with biopsies of the primary tumor site, other suspected lesions and suspected lymph nodes. Furthermore, blood samples will be collected at three time points. Main study parameters/endpoints: An accurate multimodal prediction model for the patients' individual probability of pathologic complete response after nCRT, based on the quantitative parameters derived from a longitudinal series of DW-MRI, DCE-MRI and 18F-FDG PET-CT datasets.

The incidence of Hepatocellular carcinoma (HCC) is increasing worldwide. However, most of HCC cases were at advanced stage when the diagnosis established.Early diagnosis improves the prognosis.The study is intended to evaluate the diagnostic efficiency of alpha-fetoprotein-L3 (AFP-L3) and Protein Induced by Vitamin K Absence or antagonist-II (PIVKA-II). This study is performed at Hanoi Medical University Hospital. Participants including patients with HCC and hepatic hemangioma. All the serum samples are collected before any treatments and will be tested in single center in order to decrease bias. Serum samples were tested for PIVKA-II, AFP, AFP-L3 and biochemical indexes including alanine aminotransferase(ALT),aspartate aminotransferase (AST), gamma-glutamyl transferase, HbsAg, Anti HCV, etc.

Efficacy of BCR Inhibitors in the Treatment of Autoimmune Cytopenias Associated with Chronic Lymphocytic Leukemia (CLL): A Retrospective Analysis of the French Innovative Leukemia Organization (FILO)

In this prospective study, the main goal is to evaluate the strength of Monomark -a monocyte-based transcriptomic test combined to a mathematical model- in patients with a positive FIT test. Therefore, in parallel to the routine FIT screening, blood samples will be harvested and the monocyte genetic profile will be determined. This fundamental study, will disclose the diagnostic power of a biomarker panel ("MonoMark") head to head with the well-established FIT diagnostic test, a core prerequisite for the routine use of this test as an alternative and more reliable CRC screening tool.

The third generation epidermal growth gactor receptor-tyrosine Kinase Inhibitor（EGFR-TKI） osimertinib has obvious curative effect for EGFR sensitive mutation and T790M mutation(PMID 27959700), but acquired drug resistance will occur. Previous studies show that apoptosis escape can lead to EGFR-TKI resistance.Osimertinib resistant cells show abnormal activation of PI3K/AKT/BIM activation(PMID 28765329). The classical drug aspirin can effectively decrease AKT phosphorylation and activate of BIM(PMID 28881293).So Investigators speculate that aspirin may decrease the PI3K/AKT/BIM signaling pathways, then promote osimertinib resistant cells apoptosis. The current study aims to evaluate the combination of aspirin and osimertinib in patients with EGFR/T790M mutations.

This project is a pilot study to interrogate the potential of LMS as a predictive tool for the selection of therapy for HCC patients. The reliability of LMS to predict patients' response following HCC therapy will leverage on an algorithm that is built from the pool of MRI scans from HCC patients pre- and post-treatment. In the study, MRI scans of 30 HCC and metastatic colorectal cancer (CM) patients (ratio of 4:1) will be analysed. CM cancer patients include patients whose cancers metastasized from colorectal cancer or primary liver cancer. These patients will either receive one of the treatment, surgical resection, Y90 or systemic therapy. A total of 4 MRI scans will be taken for each patient; the first MRI scan will be taken within a month before treatment initiation and the remaining MRI scans will be taken at the 1st, 3rd and 9th month post-initiation of treatment.
