Filter by:This study is designed to rigorously evaluate the safety and effectiveness of Stereotactic Body Radiotherapy (SBRT) as an innovative, non-invasive treatment for Hypertrophic Obstructive Cardiomyopathy (HOCM). HOCM, a prevalent cardiac condition, is primarily characterized by asymmetric septal hypertrophy, which results in the obstruction of the left ventricular outflow tract. This obstruction significantly compromises patient quality of life and is associated with severe risks, including arrhythmias and sudden cardiac death. While current treatments like medications, surgical septal myectomy, and percutaneous transluminal septal myocardial ablation (PTSMA) have proven to be effective, they are not without limitations. SBRT, a recent development in non-invasive cardiac radioablation, has shown encouraging results in early-stage studies, suggesting its potential as a safe and feasible option for HOCM treatment. In this study, participants will be randomly assigned to either the SBRT treatment group or a control group receiving a sham procedure. The primary objective is to measure the change in the left ventricular outflow tract pressure gradient under provoked conditions, using cardiac ultrasound at a 6-month follow-up. This will provide a clear assessment of the direct impact of SBRT on the primary physiological complication of HOCM. The study also sets forth several secondary objectives to provide a holistic view of the treatment's impact. These include evaluating changes in NYHA functional classification and KCCQ scores to assess improvements in symptom severity and quality of life, respectively. Additionally, we will monitor physical capacity through the 6-minute walk test, and biomarkers like NT-proBNP and cTNT for cardiac stress and damage. The effect of SBRT on QRS duration will be analyzed to understand its impact on cardiac electrical activity. The incidence of major adverse cardiac events (MACEs) within 6 months post-treatment will be recorded to evaluate safety, and the need for invasive septal reduction therapy post-treatment will be assessed to gauge long-term efficacy. This study aims to provide a comprehensive understanding of the potential of SBRT as a treatment alternative for HOCM. By comparing its outcomes with those of traditional therapies, the study seeks to establish SBRT's role in symptom alleviation, quality of life enhancement, and risk reduction in HOCM management.
Older patients with non-small cell lung cancer (NSCLC) treated with stereotactic body radiation therapy (SBRT) often die from other causes than lung cancer due to age-related comorbidities. This national randomized study will include 130 patients throughout 5 Danish cancer centres and investigate if a comprehensive geriatric intervention (CGA) when added upfront to SBRT for patients with localized NSCLC will have an impact on quality of life (QoL), overall survival, physical functionality and unplanned hospital admissions. If an upfront CGA improves patients' general health status, this study could lead to implementation of a CGA in standard clinical practice as well as further research on older patients receiving radiotherapy.
This pilot phase I trial aims to investigate the safety and tolerability of low dose radiotherapy (LDRT) and concurrent partial stereotactic body radiation therapy (SBRT) in combination with programmed cell death-1 (PD-1) inhibitors in Stage IV non-small cell lung cancer (NSCLC) patients who have failed standard therapy. At least 9 participants will be enrolled in this study. All will take part at West China Hospital, Sichuan University.
Hepatocellular carcinoma (HCC) is the sixth prevalent malignancy worldwide. Although surgical excision is considered the standard treatment for resectable HCC, a high rate of postoperative recurrence was observed after partial hepatectomy, with a marginal recurrence rate up to 30%. Narrow margin resection may be the most appropriate procedure for centrally located HCC because the premise for survival is the conservation of more normal liver parenchyma. Unfortunately, narrow margin resection has been reported to contribute to poor survival outcomes. However, no (neo)adjuvant therapy before (or after) hepatectomy is generally considered to be effective in reducing post-operative recurrence. Radiotherapy (RT) has been well used in many solid malignant tumors as an (neo)adjuvant to surgical treatment, including HCC. SBRT has shown encouraging rates of local control for HCC. Compared with standard fractionation radiation, SBRT can achieve more precise delivery of high-dose radiation beams to the lesion, obtaining a much smaller target volume. Meanwhile, it could be finished in a short period which can bring more convenience to patients. Recently, several study and randomized controlled trials revealed the survival benefit of adjuvant RT (IMRT and SBRT) in patients with HCC. However, there are still lack of exploration for the efficacy of neoadjuvant SBRT. This study is to analyze the safety of preoperative SBRT followed by hepatectomy for centrally located hepatocellular carcinoma.
Stereotactic body radiotherapy (SBRT) has emerged as an effective and safe treatment for low and intermediate-risk prostate cancer(PCa). However, there is no study that has investigated the effectiveness and safety of SBRT with pelvic radiation and gross target volume(GTV) boost for high-risk prostate cancer patients yet. The investigators designed a phase II clinical study of SBRT with pelvic radiation and GTV boost based on mpMRI in patients with high-risk prostate cancer.
The goal of this study is to determine the effectiveness of SBRT on reducing tumor viability at a pathologic level and also to evaluate the effects of combined modality treatment on low volume pulmonary metastases, in hopes of extrapolating this information to both primary and secondary lung cancer.
Local treatment in addition to endocrine treatment as 1st line for oligo-metastatic ER-positive/HER2-negative breast cancer.
The prognosis of small liver cancer (≤5 cm) who had underwent stereotactic body radiotherapy (SBRT) is encouraging, with the 1-year local control rate has been reported to be 95-100%, 3-year local control rate about 91%, 3-year overall survival rate around 70%. Local ablation therapy has become the standard treatment for recurrent liver cancer after surgery and interventional treatment. The ablation rate of tumors with a diameter of 3.1-5.0 cm reached 90%. The 1, 2, and 3-year survival rates had been reported to be 89%, 74%, and 60%, respectively, which is similar to that of surgical resection. At present, there is no randomized controlled study of SBRT and microwave ablation (MWA) for small liver cancer. It is hoped that this study will further compare the efficacy of SBRT and MWA for recurrent small hepatocellular carcinoma.

So far, there is no randomized controlled study comparing SBRT and surgical treatment for early-stage liver cancer. It is hoped that this study will further compare the efficacy of SBRT and surgery for early stage liver cancer.
Spinal cord compression (SCC) is a devastating complication of advanced malignancy, and can cause significant deterioration in function and quality of life (QoL). The goal of treatment is to improve functional status and symptoms, but the optimal treatment regimen for these patients has not been thoroughly established. Many patients with SCC present with uncontrolled systemic disease and poor performance status, and are not eligible for standard surgical resection. They are generally treated with 3D conformal palliative RT (3DCRT) alone, however recent trials suggest that less than 70% of patients are ambulatory, that the re-establishment of ambulation in non-ambulatory patients is poor, and the duration of improvement is guarded with radiotherapy alone. Recently, stereotactic body radiotherapy (SBRT) used alone or after previous radiotherapy to treat spinal metastasis has demonstrated superior results in pain control, tumour response and durability. SBRT requires time for careful planning, and many patients with neurologic symptoms must be treated immediately to prevent progression. Therefore the role of SBRT is still unclear in this patient population, although it seems to be a potential alternative to surgical decompression in patient not suitable for surgery. The investigators propose a feasibility study to investigate the potential benefits of dose escalation with a sequential SBRT boost to urgent 3D CRT in the setting of SCC. This regimen will allow inoperable patients to receive urgent 3DCRT while simultaneously creating the opportunity for superior outcomes with SBRT. The investigators also aim to characterize the effect on motor function and ambulation, pain and QoL. This study could stimulate further multi-center randomized trials in this area, improve motor function and patient-reported QoL, and contribute to improving oncology care in Canada in a meaningful way.
