Active clinical trials for "Neoplasms"

Iron chelation, mostly associated with multiple red blood cell transfusion, is relatively common in patients with hematological malignancies receiving allo-HSCT. This multicenter prospective observational study is designed to establish the impact of iron chelation on relapse after allo-HSCT in patients with acute myeloid leukemia and myelodysplastic syndrome. The investigators will compare the results obtained in the prospective study to those observed in a historical retrospective cohort of paired patients who did not receive chelation. Given our clinical experience and literature results, the investigators will evaluate the Exjade chelator. Although not demonstrated, the presence of mutations of the HFE gene could play an indirect role on leukemogenesis by promoting overload. It is therefore important to evaluate the status in this patient population.

Conduct a prospective study to confirm the value of circulating tumor DNA and its aberrant methylation in longitudinal monitoring of surgical lung cancer patients.

Application of circulating tumor DNA detection in diagnosis and treatment of locally advanced rectal cancer. First, to explore the feasibility of ctDNA as a detection index for rectal cancer. Second, evaluate the accuracy of ctDNA detection in rectal cancer. Third, to explore whether ctDNA can be used in the evaluation of preoperative concurrent chemoradiotherapy, so as to provide guidance for subsequent treatment. Fourth, to explore the guidance value for the decision of postoperative adjuvant therapy and the frequency of reexamination. Fifth, search for possible recurrence related mutations.

To determine incidence of Expression of aberrant CD markers in acute leukemia in South Egypt . Correlation between this expression and outcome of the patient.

Neuroendocrine cancer remains a poorly known entity. Comprehensive treatment is multidisciplinary involving surgery, radiological and nuclear medicine, and medical. A national network for the management of sporadic and hereditary malignant neuro-ENdocrine Tumor (RENATEN) is in charged of coordinating this specific care. This is part of the French National Cancer INstitute (INCa) Rare Cancer Plan. The project is in the form of an analysis of elderly population (75 years or over) with a diagnosis of neuroendocrine cancer in the western part of the France (Brittany, Pays de Loire, Normandy, Center and a part of New Aquitaine areas) representing a population of more than 12 millions of inhabitants. Oncogeriatric evaluations, specialized meetings, ...would be analysed in order to improve the care of rare cancer patients.

H3F3AK27M may be a feature of primary spinal cord glioma and affect the outcome and prognosis of TMZ chemoradiotherapy.

The primary objective of this study is to compare the testing of DNA methylation, high-risk HPV subtypes, and cytology with the definite histological results for uterine cervical lesions in a prospective cohort study. This study will include 300 unselected patients with definite histological results. All the cervical specimens of cytology collected in the clinical settings will be utilized for the testing of DNA methylation, high-risk HPV subtypes and thin prep liquid-based cytology test (TCT). The sensitivity, specificity, positive predictive value and negative predictive value were calculated based on the known histological results. The differences of DNA methylation with high-risk human papillomavirus (HPV) and TCT will also be analyzed. The testing of DNA methylation will be performed with the methylation-specific polymerase chain reaction (PCR). The TCT and HPV testing will be performed with the Roche kits.

The risk of thromboembolism is elevated in lung cancer patients. The present project investigates whether stereotactic body radiation therapy (SBRT) further increases the risk of thromboembolic disease in lung cancer patients. If coagulation is activated by SBRT, this study could form the basis of new clinical trials investigating whether lung cancer patients may benefit from thromboprophylaxis during and after stereotactic body radiation therapy.

hMe-Seal is a low-input whole-genome cell-free 5hmC sequencing method based on selective chemical labeling. It uses β-glucosyltransferase (βGT) to selectively label 5hmC with a biotin via an azide-modified glucose for pull-down of 5hmC-containing DNA fragments for sequencing. After selectively constructing 5hmC library, highthroughput-sequencing will be performed on an Illumina Nextseq-500 instrument. By ways of Rawdata processing, differential loci between Osteosarcoma group and control group will be detected to indentify specific epigenetic biomarkers of Osteosarcoma. From our previous trials, we identify geno sequencing related to beta-catenin pathways might have some relationship with osteosaroma primary or secondary drug resistance. Thus in this trial we try to further explore the drug resistance mechanism for advaced osteosarcoma second resistance to the combination therapy of Famitinib and Camrelizumab.

Gastric and oesophageal (OG) cancer associated with poor long term outcome as overall less than 25% of patients survive for more than 5 years due to late recognition of the disease. Growing evidence suggests an important role for bacteria in OG cancer and gastro esophageal reflux disease (GORD) development. About 1 in 10 people suffer from GORD and this one of the most common conditions leading to gastric and oesophageal cancer. In GORD surgical therapy is the most successful preventing cancer but around 85% of patient experience complications afterwards. Acid suppressing medications are reducing the risk of oesophageal cancer but equally increasing the risk of gastric cancer. They also shorten patients' life expectancy and often fail to provide relief. Analysis of stool samples of patients with GORD demonstrated different gut bacterial compositions to normal and rather resembled the one found in cancer. There is a clear need to improve the outcome of OG cancer. This could be achieved by identifying bacteria responsible for cancer development in gastric tissue, gastric content and saliva and potentially eliminate them hence avoid the development of cancer.
