Active clinical trials for "Neoplasms"

This study will be focused on HNC patients who have been diagnosed with HNC between 01-Jan-2013 and 30-Sep-2016.

This study is designed to confirm the efficacy of dasatinib 100mg once daily in producing a complete molecular response and to prove a possibility of "Operational Cure" in CMR patients.

Although the clinical application of differentiation therapy has made great success in the treatment of acute promyelocytic leukemia (APL), early fatal bleeding remains an unsolved problem which accounts for the main reason of induction failure in APL patients. The clinical manifestation of both serious bleeding and thrombosis illustrate the complexity of the pathogenesis of coagulopathy in APL. Despite extensive research, the pathogenesis of coagulopathy in APL is still unclear. Microparticles, 0.11μm in diameter, are small membrane vesicles released to circulation by blood cells and vascular endothelial cells during activation or apoptosis. Microparticles (MPs) derived from different cells types all exert procoagulant activity mediated by phosphatidylserine (PS) and carry some basic substances derived from their origin cells. Also, the biological activity of microparticles is often significantly higher than that of the cells they come from. According to these problems and background knowledge, our project aims to observe the roles of microparticles derived from APL cells and the procoagulant or profibrinolytic activating factors resided on these microparticles in the pathogenesis of coagulopathy in APL, and the effects of different induction therapies, chemotherapeutic drugs or differentiation agents on these microparticles and their procoagulant or profibrinolytic activating factors. To carry out this study, microparticles are obtained from patients who undergo different induction therapies at different time points or from primary bone marrow APL cells which are treated by different drugs in vitro at different time points, the expressions and activities of five procoagulant or profibrinolytic activating factors, which are highly expressed in APL cells, PS exposure and the functional state of these microparticles, will be dynamically monitored. Further study of the pathogenesis of coagulopathy in APL can provide clues and help for deep understanding of clinical manifestations, guiding clinical treatment as well as judging prognosis, and establishing theoretical basis for exploring new treatment.

Renal transplant patients have on average 3-5 times more risk of developing cancer than the general population. This rate can be increased up to 10 to 15 times in some type of cancer like kidney cancer. Among the identified risk factors, immunosuppressants and, in particular, calcineurin inhibitors (ciclosporin and tacrolimus) play a major role in increasing cancers apart from their depressant effects on the immune system. Calcineurin inhibitors (CCN) are the basis of immunosuppressive therapy in renal transplantation. Several mechanisms have been implicated to explain their pro-oncogenic properties. One related to an increase in VEGF expression seems particularly interesting in the study of renal cell carcinoma in the transplanted patient. Indeed, the physiopathology of kidney cancer has clearly been associated with an increase in the production of VEGF. Furthermore, some polymorphisms of the gene encoding VEGF have already been associated with the survival of patients with renal carcinoma and the circulating level of VEGF in the general population. The search for an association between the polymorphisms of the VEGF gene and renal carcinoma in renal transplant patients could thus identify patients whose risk of renal cell carcinoma (cRCC) post-transplantation is increased. If the involvement of certain polymorphisms in the development of cRCC was confirmed in this population, their research before the introduction of the immunosuppressive treatment would make it possible to direct the choice of treatment towards molecules without pro-oncogenic property in the Patients such as mTOR protein inhibitors (sirolimus, everolimus). This research project is therefore in line with the desire to move towards a more "personalized" medicine that could be beneficial for the patient.

This is a pilot study designed to evaluate a programme of rehabilitation for patients undergoing elective colorectal resection surgery.

The primary purpose of the study is to evaluate the efficacy and safety of supra-early post-surgery chemotherapy versus standard TEMODAL® regimen in treatment of patients with newly diagnosed glioblastoma multiforme. The secondary purpose is to assess the efficacy of supra-early post-surgery chemotherapy in release brain edema.

This is an observational prospective study. Patients diagnosed with advanced epithelial ovarian cancer (stage IC or higher) since 2008 will be asked to participate in this study by signing an informed consent. Tumour samples will be reviewed to confirm the diagnosis and to select the best regions for tissue sampling to perform the following molecular studies: array-based Comparative Genomic Hybridization and Next Generation Sequencing. Detected mutations will be analysed by Sanger sequencing. FISH probes will be designed and tested on the samples.

The goal of this laboratory research study is to learn about symptoms and activity levels of patients with OPSCC that receive IMPT or TORS.

The purpose of the study is to evaluate the ability and efficacy of using a polarization-enhanced reflectance and fluorescence imaging device, PERFIS, (see the Device Brochure) for demarcation of nonmelanoma skin cancer margins prior to surgery. PERFIS is a harmless and non-invasive device that has been used to image biological tissue both in vitro and in vivo. In this study it will be used to image nonmelanoma skin cancer lesions prior to surgery. The use of PERFIS will not affect patient care or treatment decisions in any way. No extra tissue will be used for imaging.

With this prospective, multicenter trial the investigators aim to establish the Hepatocellular Immune Score (HCCIS), a score that has been developed in a retrospective study, as a new tool for risk stratification of patients after resection of hepatocellular carcinoma that can be widely used in the clinical practice. The investigators expect to show that this score is a prognosticator for overall survival and also disease free survival. Further, it should be demonstrated that the HCCIS is a risk stratification tool that is independent from clinical or descriptive parameters. Additionally, the investigators plan to elucidate that the respective HCCIS risk groups are not only different with respect to immunological infiltration but are also different with respect to tumor biology. The finding, that tumors of the respective risk groups show different tumor biology leads to the assumption that different therapy strategies need to be applied. Therefore, in a translational approach we aim to build up a data base with HCC tumor organoids and test the effect of CD8+IL-33+ effector-memory cells on HCC tumor organoids of the respective HCCIS risk groups.
