Re-irradiation for Recurrent Primary Brain Tumors.
BACKGROUND Historically, radiation oncologists have been cautious about re-irradiating brain tumors because of concerns about the risks of late central nervous system (CNS) toxicity, especially radionecrosis, that may occur several months to years following treatment. Today there are still limited prospective data addressing this approach. MATERIALS AND METHODS Systematic review of published ...
متن کاملIs Re-Irradiation of Recurrent Metastatic Brain Tumors an Option? Re-Irradiation for Metastatic Brain Tumors With Whole-Brain Radiotherapy
Background: Relapse after whole-brain radiation therapy (WBRT) for multiple cerebral metastases occurs fairly often and is associated with a poor prognosis. Re-irradiation is an option that many defer because of risks of exceeding brain tolerance and resulting toxicity. Objective: To determine if brain re-irradiation is beneficial. Design: Single-institution retrospective study. Methods: Patien...
متن کاملRe-irradiation for metastatic brain tumors with whole-brain radiotherapy.
OBJECTIVE To determine whether second whole-brain irradiation is beneficial for patients previously treated with whole-brain irradiation. METHODS A retrospective analysis was done for 31 patients with brain metastases who had undergone re-irradiation. Initial whole-brain irradiation was performed with 30 Gy/10 fractions for 87% of these patients. Whole-brain re-irradiation was performed with ...
متن کاملPost-treatment imaging changes in primary brain tumors.
Discerning between primary brain tumor progression and treatment-related effect is a significant issue and a major challenge in neuro-oncology. The difficulty in differentiating tumor progression from treatment-related effects has important implications for treatment decisions and prognosis, as well as for clinical trial design and results. Conventional MRI is widely used to assess disease stat...
متن کاملPost-irradiation cutaneous angiosarcoma
Angiosarcoma is a rare and highly malignant tumor with potential to recur despite treatment, and carries a poor prognosis. Previous radiation therapy and lymphedema are some of the known risk factors. We present a case of cutaneous angiosarcoma which occurred at lumpectomy site in a patient with a history of breast cancer and radiation to the breast. The tumor kept on recurring repetitively des...
