Filter by:Yttrium-90, attached to microspheres, usually referred to as 90Y-microspheres or Y-90 radioembolisation, can be used in some cases to treat patients with liver tumours or liver metastasis. The treatment aim is to infuse the 90Ymicrospheres into the patient's liver. The microspheres get trapped in the lesions of micro-blood vessels while the yttrium-90, a radioactive compound, delivers radiation doses locally at these sites and damages the diseased cells. Therapy is performed in such a way the 90Y-microspheres are localised in the tumour areas minimising damage to the healthy liver tissue. This treatment requires many steps involving professionals from different medical disciplines. Patients are scanned in the nuclear Medicine Department on a gamma camera the day after the treatment. This scan is referred as Y-90 bremsstrahlung-SPECT. This posttherapy scan provides a 3-dimensional (3D) image of the distribution of the therapeutic agent in the patient's abdomen so an assessment of how much of the therapeutic agent has gone to the sites of disease can be performed. In this research project, the investigators would like to evaluate an alternative post-therapy scan to the one routinely performed on the gamma camera. The alternative scan is done on a PET-CT scanner and is referred to as Y90-PET-CT. This type of scan has been reported to provide improved quality images, providing more accurate information on the distribution of the patients therapeutic dose. For this research project, the investigators will invite a small number of patients undergoing this therapy to be scanned twice after treatment: with the current post-therapy scan on a gamma camera; and with the newly proposed scan method, Y90-PET-CT. Depending on the outcomes of this project, assessed by an expert panel of radiologists and medical physicists, the investigators will determine whether we will introduce this new scanning method into clinical practice in the future.
The purpose of the study is to determine how the behaviors of cancer caregivers can impact patients.
The study aims to assess the dynamics of incidence and mortality for all major groups of cancers for which the national data is available for the longest possible time series. The data obtained from publicly available sources are used.
The goal of this observational study is to develop a scale for cancer patients' willingness to voluntarily participate in drug clinical trials and evaluate its reliability and validity.
This prospective multicenter randomized non-inferiority trial aims to assess whether omitting dexamethasone from the premedication regimen during paclitaxel-based chemotherapy is non-inferior to the standard of care regimen that includes dexamethasone, based on the incidence of clinically relevant hypersensitivity reactions (HSRs) of grade ≥3 as per CTCAE v5.0. With a study population of 500 adult patients with solid tumors, the trial will also investigate secondary endpoints including the severity and incidence of HSRs of any grade, the number of paclitaxel administrations until the first HSR, the impact on patients' quality of life, adverse events related to dexamethasone, and the cost-effectiveness of the two premedication regimens from healthcare and societal perspectives.
People with cancer, treated for cancer, or have been recently treated for cancer are at a higher risk of becoming rapidly unwell. This is referred to as an oncological emergency and can be life-threatening. The investigators want to see if a new, standardised assessment of acute oncology knowledge and skills of all health care staff (The Acute Oncology Passport) following education and training, has an effect on the diagnosis and treatment of two relatively-common oncological emergencies: sepsis and MSCC? Sepsis is blood poisoning, which causes serious injuries if it is not diagnosed and treated as an emergency and may result in death if not treated quickly enough. MSCC is metastatic spinal cord compression, where the cancer presses on the spinal cord and can cause permanent paralysis. The investigators have chosen these two conditions, not only because of how serious and relatively common they are for people living with cancer, but also because all NHS Trusts in the UK routinely collect and report standardised data about patients who are admitted with suspected sepsis or MSCC. The investigators plan to compare data that is routinely collected about the diagnosis and treatment of patients with suspected sepsis and MSCC before and after education, training and assessment of staff about acute oncology. The investigators will conduct 'secondary analysis' on the data, as it was originally collected for another purpose. The routinely data collected at five hospital Trusts across the UK from 1st April 2023 to 30th June 2023 and 1st October to 31st December 2023 will be included in this study. This research is part of a larger UK-wide project, funded until March 2024 by NHS England Workforce, Training and Education Directorate. If acute oncology education, training and assessment of staff is shown to make a difference to patient diagnosis and treatment, the Acute Oncology Passports will be rolled-out nationally.
Soft tissue sarcomas represent a subtype of cancer that is both rare and very heterogeneous. When they are organized, their current treatment is essentially based on tumor resection surgery, +/- associated with treatment by chemotherapy and/or radiotherapy. The aim of this treatment is to reduce the risk of local recurrence (appearance of a tumor in the same region where it was first detected) and/or distant (appearance of a tumor in other regions, organs where it was first detected). Currently, no immunotherapy treatment has been approved for the treatment of patients with sarcoma. This research is based on the hypothesis that soft tissue sarcomas in which "tertiary lymphoid structures" or "TLS" are found, recognizable by a cluster of specific immune cells within the tumor, would be likely to respond better to the immunotherapy. Furthermore, the combination of immunotherapy and certain drugs targeting DNA repair has demonstrated some effectiveness in other types of cancers. The research will therefore focus on two experimental drugs : - Pembrolizumab (immunotherapy) and - Olaparib (DNA repair inhibitor). This research will make it possible to evaluate the effectiveness and safety of use of the two drugs.
In Nuclear Medicine, the examinations are long (20-60 minutes) and the patients must remain immobile, sometimes fasting. The anxiety of the latter can lead to poor quality examinations and sometimes, although already injected with radioactive drugs, the patients refuse the examination. In imaging, the use of hypnosis (prior to the MRI examination or with the patient during a scintigraphic examination) is frequent due to the conformation of MRI or scintigraphic machines, particularly for claustrophobic patients (2-2.5% of cases). Medical electroradiology manipulators (MERM) have been trained to practice Ericksonian hypnosis whose effectiveness in combating anxiety is no longer in question. Scientific studies by Faymonville et al, 2006 and Rainville et al, 2002, have shown the effectiveness of this method in managing anxiety using the simplified STAI-6 scale before and after hypnosis. The dosimetric study of the MERM position would then be greatly modified in favor of a decrease in exposure targeted by the June 4, 2018 decree on personnel safety. The impact of whether or not the MERM is physically present near the patient would also be studied. If minimal, this will resolve the current contradiction between the quality of patient care delivered and the radiation protection imposed in nuclear medicine. The investigators propose here a pilot study evaluating remote-delivered Ericksonian hypnosis versus conventionally-delivered Ericksonian hypnosis, which will allow for the sizing of a subsequent multicenter randomized non-inferiority controlled trial. Indeed, there is currently no data available on the non-inferiority margin of this technique.
In patients clinically treated with FDA-approved immunotherapy the investigators will assess the predictive value of pre- and on-treatment 1) immune-methylation profiling across cancer types, and 2) immune-methylation profiling and cytokine profiling within cancer types.
The goal of this observational study is to to look for changes within the brain, and changes in body-to-brain signals in people with cancer and people who do not have cancer. The main questions it aims to answer are: 1. Are there differences in areas of the brain known to be related to appetite control, food reward and motivation, between participants with cancer related weight loss and healthy volunteers 2. Do responses to questionnaires and computer based tasks suggest participants with cancer related weight loss have reduced appetite and reduced motivation to eat compared to healthy volunteers, and if so, do questionnaires suggest that this is associated with any other symptoms? Researchers will compare the structure and blood flow in relevant areas of the brain using MRI images between participants with cancer related weight loss and healthy volunteers. Participants will complete questionnaires and computer based tasks to allow researchers to assess areas of the brain which become more active in response to different stimuli. Some computer based tasks will be performed during the MRI scan. This is called functional MRI. A further objective is to obtain an archive of blood samples which will be stored securely for future analysis if relevant hormones or analytes are identified that may be relevant to metabolism or body composition
