ABSTRACT

INTRODUCTION: Chronic pain and disability are now well-recognised long-term complications of blunt chest wall trauma. Limited research exists regarding therapeutic interventions that can be used to address these complications. A recent feasibility study was completed testing the methods of a definitive trial. This protocol describes the proposed definitive trial, the aim of which is to investigate the impact of an early exercise programme on chronic pain and disability in patients with blunt chest wall trauma. METHODS/ANALYSIS: This mixed-methods, multicentre, parallel randomised controlled trial will run in four hospitals in Wales and one in England over 12-month recruitment period. Patients will be randomised to either the control group (routine physiotherapy input) or the intervention group (routine physiotherapy input plus a simple exercise programme completed individually by the patient). Baseline measurements including completion of two surveys (Brief Pain Inventory and EuroQol 5-dimensions, 5-Levels) will be obtained on initial assessment. These measures and a client services receipt inventory will be repeated at 3-month postinjury. Analysis of outcomes will focus on rate and severity of chronic pain and disability, cost-effectiveness and acceptability of the programme by patients and clinicians. Qualitative feedback regarding acceptability will be obtained through patient and clinician focus groups. ETHICS/DISSEMINATION: London Riverside Research Ethics Committee (Reference number: 21/LO/0782) and the Health Research Authority granted approval for the trial in December 2021. Patient recruitment will commence in February 2022. Planned dissemination is through publication in a peer-reviewed Emergency Medicine Journal, presentation at appropriate conferences and to stakeholders at professional meetings. TRIAL REGISTRATION NUMBER: ISRCTN65829737; Pre-results.

ABSTRACT

PURPOSE: Since the recognition that oligodendrogliomas may be chemosensitive, their diagnosis and clinical management has become highly controversial. Histopathology diagnosis remains challenging and new tools such as molecular genetics or molecular imaging require evaluation. EXPERIMENTAL DESIGN: In a single-center, population-based prospective study, allelic imbalance in chromosomes 1p36, 19q13, 17p13, 10p12-15, and 10q22-26 has been investigated in 19 oligodendroglioma WHO grade 2 (OII), 20 oligoastrocytoma WHO grade 2 (OAII), 8 oligodendroglioma WHO grade 3 (OIII), and 12 oligoastrocytoma WHO grade 3 (OAIII), and compared with pretherapy histopathology, computed tomography and/or magnetic resonance (CT and/or MR), [fluorine-18]fluoro-2-deoxyglucose (18F-FDG), and thallium-201 single-photon emission computed tomography (201Tl SPECT). RESULTS: In 50 cases, 18F-FDG uptake correlated with 201Tl uptake; however, 8 cases had increased 201Tl uptake but were hypometabolic for 18F-FDG, and 1 case was hypermetabolic with normal 201Tl uptake. Sixteen cases enhanced on CT/MR but failed to show 201Tl uptake; and 2 low-grade non-enhancing oligodendrogliomas had increased 201Tl uptake. Increased metabolism was more likely in high-grade cases, with 201Tl uptake more strongly correlated with grade than was 18F-FDG uptake. Tumors with 1p/19q loss were more likely to show increased 201Tl uptake and, to a lesser degree, increased 18F-FDG uptake than those without these losses. Elevated metabolism in 28% of low-grade tumors was significantly more common in tumors with 1p/19q loss, and increased uptake of both 18F-FDG and 201Tl in low-grade cases was found only in those with 1p/19q loss. CONCLUSIONS: In this study, dissociation of uptake of contrast agents and radiotracers suggests independent deregulation of the blood-brain barrier breakdown and metabolism during disease progression of oligodendroglial neoplasms, and the association of elevated metabolism with 1p/19q loss, particularly in low-grade tumors, may have implications for clinical management.
