Technique for sparing previously irradiated critical normal structures in salvage proton craniospinal irradiation
BACKGROUND Cranial reirradiation is clinically appropriate in some cases but cumulative radiation dose to critical normal structures remains a practical concern. The authors developed a simple technique in 3D conformal proton craniospinal irradiation (CSI) to block organs at risk (OAR) while minimizing underdosing of adjacent target brain tissue. METHODS Two clinical cases illustrate the use ...
متن کاملCase Report of Bone Marrow-Sparing Proton Therapy Craniospinal Irradiation for Central Nervous System Myelomatosis
Central nervous system (CNS) involvement is rare but it is an increasingly recognized complication of the multiple myeloma. The craniospinal radiotherapy is a standard treatment option, however, it may be challenging to deliver due to hematologic toxicity in the patients with multiple prior systemic therapies. We report a case of CNS myelomatosis in a patient with prior stem cell transplant mul...
متن کاملSalvage SBRT for Previously Irradiated Lung Cancer
Purpose: Patients with locally recurrent lung cancer after definitive radiation therapy pose a challenge in management. Surgery is often not an option and chemotherapy offers poor long-term local control. Stereotactic body radiotherapy (SBRT) was investigated in an attempt to salvage locally recurrent lung cancer. Materials and Methods: From March, 2009 to January, 2010, 8 patients who had prev...
متن کاملStandardized treatment planning methodology for passively scattered proton craniospinal irradiation
BACKGROUND As the number of proton therapy centers increases, so does the need for studies which compare proton treatments between institutions and with photon therapy. However, results of such studies are highly dependent on target volume definition and treatment planning techniques. Thus, standardized methods of treatment planning are needed, particularly for proton treatment planning, in whi...
متن کاملEffects of vertebral-body-sparing proton craniospinal irradiation on the spine of young pediatric patients with medulloblastoma
PURPOSE To investigate the long-term effects of vertebral-body-sparing proton craniospinal irradiation (CSI) on the spine of young patients with medulloblastoma. METHODS AND MATERIALS Six children between the ages of 3 and 5 years with medulloblastoma were treated with vertebral-body-sparing proton CSI after maximal safe resection. Radiation therapy was delivered in the supine position with p...
