Filter by:Open-label, non-randomized, phase II multi-centre controlled clinical trial. 51 non-resectable stage IIIA-IIIB non-small cell lung cancer patients will be enrolled in this trial to evaluate the efficacy of the treatment (Atezolizumab + Induction chemotherapy (CT) + CT-Radiotherapy) in terms of the Progression Free Survival at 12 months
In the context of malignant disease, it is likely that vaccine efficacy and immunogenicity depends on the type of pathology, stage of the disease, immunosuppression induced by the treatments, in addition to more classic factors such as age, general condition and possibly the type of vaccine used. There are very little data on the efficacy and immunogenicity of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in patients with malignant disease in the active phase of treatment. This multicenter observational study aims to assess the efficacy and the immunogenicity of anti-Sars-CoV-2 vaccines in the cohort of patients treated for malignant pathology (solid or hematological tumors) at Saint Louis Hospital and in thoracic oncology patients at Bichat Hospital.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of escalating doses of RMC-5552 monotherapy in adult participants with relapsed/refractory solid tumors and to identify the recommended Phase 2 dose (RP2D).
Background: NF1 is a genetic syndrome. Tumors appear early in life. Many people with NF1 develop PN. These tumors can become an aggressive cancer called MPNST. People with MPNST may benefit from treatment with a MEK inhibitor (MEKi). Researchers want to learn if there is an increased risk of MPNST formation from MEKi treatment in people with NF1. To do this, they will review data that has been collected in NIH NF1 studies. Objective: To describe the characteristics of people who have taken part in NF1 studies at NIH and to compare the risk of MPNST formation in those treated with MEKi or other PN-directed treatment. Eligibility: People with NF1 who were seen at NIH from Jan. 1, 1998, to Jan. 1, 2020. Design: Participants medical records will be reviewed. Participants who opted out of future use of their data will not be included. Demographic data, like sex, race, and date of birth, will be collected. Data about MEKi and non-MEKi treatments will be collected. Clinical data, such as surgery and treatment details, will be collected. The differences between all participants who were seen at NIH for any NF1 related study will be compared. Participants will be put into 4 groups: History of MEKi therapy Treatment with tumor directed therapy other than MEKi Treatment with both MEKi and non-MEKi tumor directed therapies No tumor directed medical therapy Participants with NF1 who were treated for PN with either a MEKi treatment or a non-MEKi treatment will also be compared. The study will last for 3 to 6 months.
Background: In Argentina, central nervous system (CNS) solid tumors (19%) and non-CNS solid tumors (25%) account for 44% of pediatric tumors. The new World Health organization (WHO) 2016 classification, which includes genomic characterization, comprises more than 100 CNS tumor entities and subclasses. In children, glial lineage tumors (gliomas) are the most frequent and comprise astrocytomas, ependymomas and oligodendroglioma, while embryonal CNS tumors are a heterogeneous group of WHO grade IV tumors. Pediatric soft tissue tumors (STT) present difficulties for accurate diagnosis since their morphological and immunophenotypic features overlap among the different histological patterns. The emergence of new molecular techniques has generated a great advance in the field of solid tumors, particularly in the molecular definition of groups of patients. This fact makes tailor-made treatment feasible, according to the biology of the tumor. In particular, in children, the identification of treatment targets is especially important since it may avoid unnecessary sequel in a growing child. This project allows the articulation between basic and clinical research groups, thus consolidating the objective of basic translational research and generating both clinical and basic knowledge about the pathogenesis of pediatric solid tumors in our country. Aim: To standardize and implement a comprehensive multi-level molecular strategy, using medium and high complexity techniques, for the detection of molecular alterations in primary pediatric solid tumors (neuroblastoma, rhabdomyosarcoma, Ewing sarcoma family tumors, soft tissue sarcomas and CNS tumors (gliomas and embryonal)), that can be applied to the diagnosis, prognosis and/or use of targeted therapies against molecular targets in order to provide a tailored therapeutic opportunity. Material and methods: Pediatric cases of solid tumors will be enrolled prospectively. Based on the statistics of the participating centers, 100 samples will be included. From each case, a formalin fixed biopsy will be available and when possible, a fragment will also be preserved at -70ºC. Clinical and follow-up data will be obtained from the clinical records. The methodological approaches include: 1) Immunohistochemical detection of tumor lineage determinant markers, some of them with predictive value. 2) FISH (fluorescence in situ hybridization) with break-apart strategy for genes involved in recurrent chromosomal translocations and locus-specific design probes for other unbalanced structural chromosomal structural alterations (amplifications and deletions of genes or chromosomal segments). 3) Real time (RT)-polymerase chain reaction (PCR) detection of fusion transcripts resulting from chromosomal translocations. 4) Quantitative polymerase chain reaction (qPCR) and Sanger sequencing analysis of single nucleotide polymorphisms (SNPs) as targets for therapy. 5) Sanger sequencing analysis of fusions, ins/del as a complement to RT-PCR or FISH (fluorescence in situ hybridization), 6) Next Generation Sequencing (NGS) with a specific and customized panel containing all necessary genes to define a tumor´s genomic mutation profile for diagnosis, risk stratification and prognosis of pediatric tumors. However, NGS sequencing will only be applied in those cases which could not be resolved with the previous strategies or cases with poor evolution Based on the above analyses, an integrated analysis algorithm will be developed according to WHO recommendations, but adapted to the facilities of the institution. Molecular findings will be correlated with clinical and histological data
This is a Phase 1/2, multicenter, open-label trial of avapritinib in participants 2 to < 18 years of age with advanced relapsed/refractory (R/R) solid tumors, including central nervous system (CNS) tumors, that harbor a PDGFRA and/or KIT mutation (including non-synonymous point mutations, insertions, and deletions) or amplification, or DMG-H3K27a who have no available curative treatment options. This is a single-arm trial in which all participants will receive avapritinib. The study consists of 2 parts: dose confirmation, safety, and PK (Part 1) and initial efficacy, safety, and PK at the Part 2 recommended dose (Part 2).

Background: Advanced cancer may cause functional limitations, subsequently leading to decreased ability to perform and engage in everyday activities, such as self-care, household, leisure and civic life. In addition, people with advanced cancer need alleviation from the pain and sorrow following limited life expectancy wherefore they prefer to focus on everyday life function and activities, lightness and enjoyment. The overall aim of the Balance, Activity and quality of Life (BAL) project is to develop, test and evaluate effectiveness and process of a resource-oriented intervention which coordinates rehabilitation and palliative care to enhance quality of life (QoL), balance and enjoyment in everyday activities and functioning. The development of the intervention is guided by the British Medical Research Council's guidance (MRC). The present study consists of a resource-oriented intervention, which will be feasibility tested in the research clinic of REHPA, the Danish Knowledge Centre for Rehabilitation and Palliative Care. The study will inform the development of a resource-oriented program for people with advanced cancer. Material and Methods: A feasibility study designed as a one-armed, pre-post study with follow-up after five days and again after 6 and 12 weeks. The study will recruit 20-25 home-living adults (⩾18 years) with chronic or advanced cancer reporting needs in everyday life. Outcomes are quality of life, physical function and fatigue assessed using the European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire Core 30 (EORTC QLQ C-30). Furthermore, balance in everyday activities will be assessed using the Occupational Balance Questionnaire 11 (OBQ-11). Besides outcomes, process data will also be collected regarding: 1) fidelity, 2) adherence, 3) dose and 4) reach and mechanisms of impact with attention to participant's experiences of and interactions with the intervention. These data will be collected using registration forms, questionnaires, participant-observations and focus-group interviews.
This is a single arm interventional molecular analysis study with no administration of investigational product and no masking. This multicenter study will involve participants with advanced/metastatic disease for the purpose of collecting tumor tissue and blood samples for broad molecular analysis and examining the expression of specific biomarkers using validated clinical assays.
Dexmedetomidine is a highly selective alpha2-adrenergic receptor agonist with sedative, analgesic, anti-anxiety, and inhibitory sympathetic nerve excitation properties. It is commonly used in clinical anesthesia and intensive care.Radical gastrectomy for gastrointestinal malignant tumors is a common major operation in clinical practice, with long operation time, great trauma and strong stress response of patients. Dexmedetomidine is often used in general anesthesia during such operations, but its long-term use or large dose may produce certain side effects.Common side effects of dexmedetomidine include bradycardia and hypotension, etc. Previous studies have reported that dexmedetomidine can prolong QT interval and is at risk of causing tip torsion type ventricular tachycardia.Abnormal Potassium may affect myocardial repolarization and increase the risk of tip torsion ventricular tachycardia.The main purpose of this study was to observe the effects of long-term use of dexmedetomidine on perioperative internal environment such as electrolyte and rehabilitation indicators during radical general anesthesia for gastrointestinal malignancy, and the secondary purpose was to explore the optimal dose of dexmedetomidine for general anesthesia for patients undergoing radical general anesthesia for gastrointestinal malignancy.
