Filter by:Alterations involving the ROS (v-ros UR2 sarcoma virus oncogene homolog 1) gene such as mutations, overexpression and gene rearrangements has been implicated in carcinogenesis and has been demonstrated to be a relevant target for ALK inhibitors. While emerging reports have demonstrated the role of ROS rearrangement in non-small cell lung cancer and cholangiocarcinoma, the functional significance of ROS dysregulation in solid tumors remain largely unstudied. The investigators aims are: (1) To characterize the frequency of ROS gene fusion, ROS protein overexpression and ROS gene mutations in cell lines and tumors from patients with hepatocellular carcinoma, colorectal, gastric, breast, ovarian, cholangiocarcinoma and non-small cell lung cancer, (2) To identify novel ROS gene variants in human solid tumors harboring ROS aberrations using next generation sequencing (NGS), (3) To determine the functional relevance of novel ROS gene variants identified with NGS, (4) To characterize the sensitivity of cells with functionally relevant ROS aberrations using ROS tyrosine kinase inhibitors. ROS fusions and protein overexpression will be screened in a panel of cell lines and primary tumors using Fluorescence In-situ Hybridization and immunohistochemistry respectively. Targeted next-generation sequencing will be applied to identify ROS variants in matching cancer types demonstrating high levels of gene fusion and protein overexpression. Functional characterization of novel ROS variants will be performed by silencing (shRNA) and overexpressing candidate cell lines with the respective ROS mutations/fusions, and evaluating their effects on biological functions including cell proliferation, migration, invasion and apoptosis, as well as sensitivity against ROS/ALK inhibitors. The investigators anticipate findings from this study will improve the investigators understanding of aberrant ROS signaling in an expanded group of cancer types, and potentially identifying a larger group of cancer patients that will benefit from ROS targeted therapy. Further insight of the role of ROS receptor tyrosine kinase will confirm it as a therapeutic target in human solid tumors and hence expand the indication of crizotinib and other dual ALK/ ROS inhibitors. Furthermore, given the rarity of ROS fusion receptor tyrosine kinase in reported cancers, defining the epidemiology of ROS aberrations in other unreported cancers harboring ROS pathway activation is essential to properly design future clinical trials of ROS inhibitors. The validation of ROS receptor tyrosine kinase will also provide a new therapeutic target in the treatment of cancer and expand the role of novel targeted agents. Findings from this study will further the investigators knowledge on the oncogenic functions of the ROS and the application of ROS inhibitors in an extended group of solid tumors.
Using Shen-Mai-San for cancer patients undergoing chemotherapy or radiotherapy could help these people improve the quality of life.
The study hopes to contribute to the development of technologies of ovarian tissue freezing-thawing and in vitro maturation of immature eggs such that a person at risk for premature ovarian failure might be able to conceive a genetically related child.
A research study on the diagnosis of spread of disease for children who have been diagnosed with solid tumors using a new whole body imaging technique and a new MR contrast agent (ferumoxytol). Standard tests that are used to determine the extent and possible spread of a child's disease include magnetic resonance (MR) imaging, computed tomography (CT), Positron Emission Tomography (PET) as well as bone scanning, and metaiodobenzylguanidine (MIBG) scanning. The purpose of this study is to determine if newer imaging tests referred to as whole body diffusion-weighted MR and whole body PET/MR can detect the extent and spread of the disease as accurately or even better as the standard tests (CT, MR and/or PET/CT). The advantage of the new imaging test is that it is associated with no or significantly reduced radiation exposure compared to standard CT and PET/CT imaging tests. The results of whole body MR and PET/MR will be compared with that of the conventional, standard imaging studies for tumor detecting.
The investigator is looking for patients who have been diagnosed with stage 1-4 cancer to enroll in a five year Quality of Life clinical trial study in which the participant has previously elected to use Insulin Potentiation Targeted Low Dose (IPTLD) as a means to treat their illness. This study is a quality of life study and not a treatment study. Participants participating in the study will be asked to complete quality of life questionnaires. The questionnaires completed by the patients will measure mood, energy level, ability to function, level of pain, and other measures that indicate how a patient feels about the quality of their daily living.
The purpose of this study is to assess the efficacy and safety of Ramosetron, Aprepitant and Dexamethasone therapy versus Ondansetron, Aprepitant and Dexamethasone therapy for preventing of nausea and vomiting in highly emetogenic chemotherapy (ROAD study): Prospective multicenter, randomized, single blinded, phase III study.
Phase 1: Baseline investigation (nation-wide survey) Aims: To investigate whether diabetes and prediabetes is a risk factor for cancers of all sites as well as for specific type of cancer, such as breast and colorectal cancer. Subjects and Methods: A nation-wide survey will be carried out in 200,000-250,000 individuals selected from 20-25 communities stratified according to geographic regions (northeast, north, east, south central, northwest, and southwest China), degrees of urbanization (large cities [Beijing, Shanghai, and provincial capitals], midsize cities, county seats, and rural townships), and economic development status (as assessed on the basis of the gross domestic product [GDP] for each province). A comprehensive examination including questionnaire, anthropometric measurements, biochemical analysis will be performed in each study participant. Diabetes and prediabetes should be diagnosed by OGTT according to the WHO 1999 criteria, while the diagnosis of cancer is established on the self-report questionnaire and cross checking with the tumor registry or a proof of doctor's diagnosis. Phase 2: Cohort follow-up Aims : To examine factors that modify the risk of cancer in diabetes, prediabetes and normal glucose regulation (NGR). Subjects and Methods: To recruit and follow all type 2 diabetes, prediabetes, and sex,age-matched NGR (1:1) in each community for at least 3 years. For diabetes, treatment target is HbA1c ≤ 7.0% with treatment paradigm recommended by local guideline.
The Biorepository for Caris Life Sciences is designed for the purpose of making quality biospecimens and associated clinical data available for research studies related to advancing precision medicine and improving care for patients. The Caris Biorepository is a repository of prospectively collected biological specimens and associated clinical and demographic data gathered from multiple sources to be stored, used and shared for research. Caris Life Sciences will maintain the data and specimens and will control access to and use of the information and specimens by multiple individuals for multiple purposes which may evolve over time.
The goal of this clinical research study is to collect information about the long-term safety of gene transfer therapy. This study is also designed to create a database of medical information about patients who have received gene transfer therapy, in order for researchers to track and review the long-term safety and any effects (good or bad) of gene transfer therapy.
Bone is a common site of metastasis for a range of malignancies. Bone metastases have the potential to cause significant morbidity including pain, impairment of ambulation and reduced functional independence. Previous research has shown that pathological fractures are observed in 9 to 29 percent of patients with long bone metastases, and a high proportion of these require surgical intervention to relieve pain and restore function. The goal of this study is to describe the clinical outcomes of patients with femoral metastases at high risk of pathological fracture. Patients referred for treatment of femoral metastases at high risk of fracture will be followed prospectively after undergoing with surgery (± post-operative radiotherapy), or radiotherapy alone. Patient and disease characteristics, ambulatory status and limb function will be documented before treatment. These Clinical outcomes of participants in each treatment group will be measured 6 weeks after treatment, and 3- and 6 months after enrolment, with particular reference to patient-reported outcomes relating to pain, ambulatory status, limb function and quality of life.
