Filter by:HCC patients with PVTT (main trunk or the first-degree branch) treated with the combination of pembrolizumab (Ketruda), lenvatinib (Lenvima), and SBRT.
To evaluate the safety and efficacy of combination of Sintilimab and SBRT on the basis of platinum-containing chemotherapy as the first-line treatment of limited metastatic head and neck squamous cell carcinoma (LM-HNSCC).
This is a prospective, investigator-initiated, phase II, multicentre-study, investigating the efficacy and toxicity of definitive SABR of osseous oligometastases, when pragmatically introduced into a daily clinical setting.
Macrovascular invasion (MVI) is common in HCC, Portal vein tumor thrombus (PVTT) is the most common form of MVI in HCC, with an incidence ranging from 44 to 62.2%. About 10% to 60% of HCC patients have PVTT at the time of diagnosis. the prognosis for those with PVTT remains poor, as their median survival is only 2-4 months via supportive care. There is currently no widely-accepted consensus for the management of HCC with PVTT. According to some guidelines in Europe and America, HCC with PVTT is regarded as Stage C per Barcelona Clinic Liver Cancer (BCLC) Staging system, and sorafenib alone is recommended as the treatment of choice. This study is to analyze the safety and efficacy of radiotherapy of hepatocellular carcinoma patients with portal vein tumor thrombosis.
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.
