SRS dose escalation for brain metastases in radiation-naïve patients will establish true tolerable doses, which may exceed the current standard doses. This may lead to an improvement in local control, patient survival, and/or quality-of life.
This trial aims to assess the impact of SRS on overall survival, PFS, radiation toxicity and quality of life as compared to WBRT in oligometastatic brain disease in breast cancer patients. Total 98 patients with breast cancer with brain oligo-metastases will be included. The WBRT dosage schedule will be 30 Gy in 10 fractions over 2 weeks. For tumors with 2cm, SRS dose of 22 to 25 Gy will be delivered and tumor larger than 2 cm will be treated with doses of 18 to 20 Gy.
This prospective 2-stage, non-randomized Phase 2 trial evaluates the safety and efficacy of FSRT for the management of hemorrhagic brain metastases
The management of brain metastases has evolved́ rapidly in recent years. It is estimated that 20% to 40% of cancer patients will develop brain metastases (BM) during the course of their disease. Whole-brain radiotherapy has long been the first-line treatment for brain metastases. However, large-scale international clinical trials conducted over the past decade have established stereotactic radiotherapy (SR) as the treatment of choice for the management of brain metastases (BM). However, even though the method of radiation delivery has evolved considerably, the problem of monitoring and managing brain metastases remains unresolved. ...
The purpose of this research is to identify biological characteristics occurring in the initiation and progression of melanoma.
Background: - Skin disease can have many causes. It can have widespread consequences, and in rare cases can lead to death. Researchers want to determine the causes of various types of skin diseases and find a way to treat them. Objectives: - To determine the causes of various skin diseases and find ways to treat them. Eligibility: - People ages 2 and older who have: - A skin disease or at risk of developing a skin disease OR - A family member of persons with a skin disease - Healthy volunteers ages 2 and older Design: - Participants will be screened under...
This study is to evaluate the efficacy and safety of QBS72S in participants with advanced, relapsed, metastatic breast cancer with CNS involvement.
This is a phase 3 study to compare the efficacy and safety of HBI-8000 or Placebo combined with nivolumab on patients with unresectable or metastatic melanoma and eligible patients who are not adolescents or patients with new, progressive brain metastasis will be stratified by PD-L1 expression and LDH level.
Immunotherapy (IO), such as treatment with anti-PD-1, PD-L1, or CTLA-4 inhibitors, is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. However, the optimal duration of immunotherapies is currently unknown. Our hypothesis is that a reduced dose intensity of IO could be as effective as the current standard treatment in term of prevention of the disease progression. If proved right, this study will have a positive medico-economic impact by reduction of the costs associated with the treatment and the toxicity, and an increase of the patients' quality of life.
This trial studies health outcomes after treatment in patients with retinoblastoma. Gathering health information over time from patients and family members through vision assessments, samples of tissue and saliva, and questionnaires may help doctors learn more about what causes retinoblastoma, identify long-term health outcomes for patients with retinoblastoma, and find out which therapies may be the best for treating retinoblastoma
