Active clinical trials for "Neoplasms"

To evaluate the role of the LungPoint VBN System in the bronchoscopic access to a target location. The evaluation will explore: Ability of the system to guide a user to one or more target site(s) Ease of use of the system (assessment of the user interface) Incremental value brought by the use of the system to the successful completion of a case.

With the preliminary anatomical and histological study, the membranous structures of the sellar region was considered to be closely related with the growth pattern of Craniopharyngiomas(CP). By combined considering of the tumor-membrane relationship, this project was trying to classify the CP through retrospectively summarizing the pre- and postoperative imaging (MRI and CT), the intrasurgical findings, and the endocrine data of 198 CPs with primary surgery in our hospital (since 1997 until now). As a result, a distinct and systematic CP classification was proposed. The possible originate site, surgical skills and postoperative treatment of all the subtype tumors were discussed and analyzed to provide a normalized surgical treatment for this kind of tumor. Then in the prospective cohort, the anticipated 100 CP patients will accept the normalized surgical treatment. And by the long term follow up, the postsurgical quantity of life (QOL) of patients was evaluated with aspect in cognition, circadian rhythm, endocrine, Water-Electrolyte and body weight, et al. By comparing with the long-term results of the retrospective cohort, the totally follow up data was statistically analyzed to assess the rationality of this standard treatment of CP.

Descriptive registry to investigate frequency of HER-2 positive gastric cancer involving CNS. Exploration of additional prognostic factors for brain involvement from gastric cancer.

Pituitary adenomas is a very common disease, but the cause and genetics hasn't been identified. The investigators are going to use genome-wide association study to identify genes that may be related to pituitary adenomas.

Adult acute lymphoblastic leukemia treatment approaches relie on risk stratification, including cytogenetics. We want to study at diagnosis several blast cells parameters on frozen samples of GRAALL protocols enrolled patients: A CD45-DNA double staining analysed by flow cytometry will allow mesurement for each blastic clone of DNA ploidy, percentage of cells in S-phase, CD45 fluorescence index. The proteine P16 metabolic way, involved in cell cycle regulation, will be studied by Western Blot analysis. The comparison between these parameters, and main haematological data, will be followed by a prognostic analysis, based on blast corticosensibility in vivo, chimiosensibility, complete remission, and survival. Combination of the studied parameters will allow to appreciate a clonal diversity. This will help to predict, at diagnosis, high probability of resistance to treatment.

The role of vascular endothelial growth factor-C (VEGF-C) and its receptors induced lymphangiogenesis and host inflammatory responses on the carcinogenesis of oral cancers and premalignant lesions

We will explore the genetic (including APC, k-ras, p53, MSI, etc.) and environmental (including family history, life style, diet, nutritional status, DM, serum IGF-I, IGFBP-3, etc.) risk factors of colorectal tumorigenesis. We will accrue approximately 1000 patients as experimental group. The control group consists of 2000 individuals who were confirmed without colorectal cancer or polyps by colonoscopy. We estimated the statistical power of this study will reach more than 90%. In the second year, we will explore the association between various environmental risk factors with the epigenetic changes of various oncogenes and tumor suppressor genes. Firstly, we will study the correlation between hypermethylation of promoter region of hMLH1 gene with various environmental factors. Next, we will explore the genetic polymorphisms of promoter of E-cadherin gene. Recently, it has been reported that the C→A genetic polymorphism in the promoter region of E-cadherin gene in prostate cancer. Since this phenomenon has not been reported in colorectal cancer, it is mandatory for us to extend our research to the E-cadherin polymorphisms of colorectal cancer. Moreover, this project will focus on exploration of the association between the genetic polymorphisms of promoter of TS gene with chemosensitivity to 5-Fu-based therapy. We speculated that the better prognosis in colorectal tumors with MSI is related to their expression of TS gene. In summary, the second year of this project will extend our accumulated experience in the study of genetic polymorphisms to further clarify the association between genetic polymorphisms of TS gene with the prognosis of colorectal cancers after chemotherapy. We believe that this project will facilitate: (1) the further clarification of colorectal cancer tumorigenesis; (2) the establishment of domestic epidemiological data of colorectal cancer of Taiwan, and (3) the improvement of the quality of clinical management of patients with colorectal cancer.

This study aims to describe the impact of a training in therapeutic education on the relation between a caregiver and his/her patients. Subjects are recruited among health professionals attending a training in therapeutic education. Then they are asked to identify up to 5 of their patients to be contacted by the researcher for an interview. Individual semi-structured interviews are conducted with 20 duo "caregivers / patients" before the training, 1 month and 6 months after the training.

Primary mucosal melanomas (MPM) are rarer than cutaneous melanomas, but also more severe. They are usually refractory to conventional approaches, regularly excluded from major therapeutic programs and not sensitive to new targeted therapies orphans. " The identification of therapeutic targets and accessibility to existing, developing or future targeted therapies improves the survival of patients with MPM. The principal goal is to describe, using a large panel of genes, the prevalence of major mutations in a cohort of MPMs based on the population of a French region.

This is a prospective, multicenter, non-interventional, controlled clinical study. Evaluate MDT performance and benefit analysis in patients with advanced gastric or colorectal cancer after MDT discussion under real medical practice.
