NCT ID: NCT05533541 Recruiting - Radiation Disease Clinical Trials

Pelvic Radiation Disease in Childhood Cancer Survivors

Start date: October 1, 2023
Phase:
Study type: Observational

This study aims to characterise the impact of radiotherapy on physical symptoms and quality of life in childhood and young adult cancer survivors. This is in line with current NHS strategic priorities and an unmet clinical need to optimise aftercare in this patient group. In order to provide effective treatment strategies, the scale and impact of symptom burden requires better characterisation. A significant proportion of adult patients suffer with gastrointestinal and urinary symptoms and sexual dysfunction following radiotherapy treatment. However there is a lack of data in the paediatric and young adult population. We will study patients who underwent abdomino-pelvic radiotherapy, who completed treatment between 2000 and 2021 and were under the age of 24 years at the time of treatment. Patients will be recruited from The Royal Marsden Hospital, Great Ormond St Hospital and University College Hospital. Once these patients are identified we propose to prospectively assess severity of their ongoing symptoms using an electronic questionnaire, including relevant extracts from existing validated questionnaires. Treatment and patient related factors will be extracted from patient hospital records. A further qualitative arm of the study will be completed on a sub-set of 10 patients. We will identify appropriate patients that are willing to participate in qualitative research at the time of consenting. One-to-one interviews will be conducted to gain a better insight into their symptom burden, quality of life, patient perceptions of current services and view of currently unmet needs. This study will provide novel data on the frequency and severity of gastrointestinal and bladder related radiotherapy toxicity in young adult cancer survivors and assess impact on sexual function and quality of life. We would then propose to use this data to focus on service improvements within the regional paediatric and TYA cancer aftercare service driven by patient experience and clinical need.

NCT ID: NCT05246774 Recruiting - Prostate Cancer Clinical Trials

Study of Serum and Urinary Biomarkers and Radiation Cystitis in Patients Treated With Radiotherapy for Localized Prostate Cancer

RABBIO
Start date: March 1, 2022
Phase:
Study type: Observational

Prostate cancer represents the 1st diagnosed cancer in men, with 50400 new cases and 8100 deaths in 2018. Improved diagnostic and therapeutic strategies have led to a 3.7% decrease in mortality between 2010 and 2018 with a 5- and 10-year survival rate of 93% and 80%, respectively. Pelvic conformal radiotherapy is an important therapeutic technique in the management of pelvic cancers, particularly prostate cancer. However, despite the improvement in radiation techniques, this technique is responsible for acute and late adverse events at the bladder level, these symptoms being grouped under the term radiation cystitis. It has a clear impact on the quality of life of patients. Acute radiation cystitis is likely to occur during treatment or within 3 months after radiotherapy. Its incidence is estimated at nearly 50%. The late form appears on average 2 years after radiation, but can sometimes occur 10 or 20 years later. Its incidence is 5 to 10% of cases. Although certain factors have been identified, such as the dose received, fractionation or comorbidities, the pathophysiology of radiation-induced cystitis remains unclear, particularly because of the risks of complications arising from access to bladder tissue post-irradiation, thus limiting our knowledge as well as the therapies targeting this process. The use of biomarkers in liquid biopsies allows us to understand the problem of access to irradiated tissues and to highlight protein changes, prognostic of radiation-induced visceral toxicity. Few works are published on the evaluation of inflammatory and pro-fibrotic biomarkers of radiation-induced cystitis in liquid biopsies. Only 2 retrospective studies have shown a correlation between late radiation cystitis and increased levels of plasminogen activator inhibitor 1 (PAI-1), matrix metalloproteinase inhibitors (TIMP1 and TIMP2), hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and placental growth factor (PIGF) in urine. However, none of these studies explored the variation of biomarkers in the early stage of radiation-induced bladder toxicity. This would suggest the feasibility of prospective assay of overexpression of these proteins in liquid biopsies.

NCT ID: NCT04701749 Recruiting - Clinical trials for Non-valvular Atrial Fibrillation

Study of the Effects of Anticoagulant Interruption Covered by Percutaneous Left Atrial Occlusion in Patients With Chronic Atrial Fibrillation and Radiation Cystitis at Risk of Bleeding

HEMOCC
Start date: February 24, 2021
Phase:
Study type: Observational

The etiology of the radiation cystitis is a pelvic irradiation generally performed as part of the treatment of prostate cancer. The incidence is 50,000 new cases per year. Approximately 35% of prostate cancer treatment is radiotherapy. The prevalence of haematuric radiation cystitis is 4-5% (about 800 patients). One of the complications of radiation cystitis is persistent hematuria. There is currently no curative treatment for this hematuria. There are few treatment options with a random probability of improvement of this symptomatology. These haematurias are rarely resolved spontaneously and most of the time involve emergency room management with +/- invasive procedures, sometimes by hospitalisation, always with a significant psychological impact on the patient. Furthermore, lifetime anticoagulant treatment considerably increases the likelihood of bladder bleeding. This is the case of patients being followed for Atrial Fibrillation Cardiac Arrhythmia (AFCA), which by definition carries a major cardioembolic risk, and who will be of particular interest in this study. In recent years, cardiologists have developed an alternative to anticoagulants: left atrial appendage closure or left atrial occlusion (LAO) . This procedure consists of inserting a nitinol prosthesis in the left atrium, the site of more than 90% of thrombi formation in non-valvular atrial fibrillation. This minimally invasive procedure lasts about 15 minutes and is performed during a 48-hour hospitalization. Anticoagulants are stopped the day after the setting up procedure. Several studies have shown non-inferiority of atrial closure and anticoagulants to thromboembolic events in non-valvular atrial fibrillation. In addition, LAO allows the permanent discontinuation of anticoagulants, associated with the cessation of anticoagulant bleeding adverse events. While studies have been conducted on the impact of this technique on patients monitored in cardiology, no studies evaluate the value of LAO in anticoagulated patients with a hematuric radiation cystitis. This tprocedure is already used in routine care for patients followed in urology, and has shown encouraging results, since 8 out of 10 patients saw a significant reduction in the number of haematurias, but it has never yet been scientifically proven to be effective, hence the aim of this study. The interest of this study will therefore be : - To evaluate the potential benefit of left atrial appendage closure on the number of episodes of hematuria. - To evaluate the economic benefit in reducing the number of hospitalizations, surgeries and complications for hematuria as well as the discontinuation of anticoagulants. As the patient's data must be retrieved regardless of the patient's subsequent management (with or without a cardiac procedure) within the framework of the HEMOCC protocol, it will be proposed to the patient as soon as he or she is consulting for haematuria on radiation cystitis. The patient will be followed for 3 years. The mainly descriptive analyses will be collected in the form of a register and carried out by a biostatistician from Clermont-Ferrand University Hospital.
