Introduction. Primary central nervous system lymphoma is a rare entity mostly presenting with non-GCB diffuse large B-cell lymphoma, being confined to the brain, spinal cord, meninges, and eyes. Diagnosis. The diagnosis frequently established by stereotactic or open brain biopsy, but in some cases isolated leptomeningeal involvement, only way identify atypical/monoclonal lymphocytes cerebrospin...

The recurrence and progression of brain metastases after brain irradiation are a major cause of mortality and morbidity in patients with cancer. The risk of radiation-induced neurotoxicity and efficacy probably leads oncologists to not consider re-irradiation. We report the case of a 48-year-old Asian male diagnosed with squamous cell lung cancer and multiple brain metastases initially treated ...

This study is the first one to compare WBRT+SRS to OP+WBRT for 1-3 brain metastases. Survival (OS), intracerebral control (IC) and local control (LC) of the treated metastases were retrospectively evaluated in 52 patients undergoing WBRT+SRS and in 52 patients undergoing OP+WBRT. Both groups were matched for WBRT schedule, age, gender, performance status, tumour, number of brain metastases, ext...

PURPOSE To evaluate the prognostic factors associated with overall survival in patients with brain metastasis treated with whole brain radiotherapy (WBRT) and estimate the potential improvement in survival for patients with brain metastases, stratified by the Radiation Therapy Oncology Group (RTOG) recursive partitioning analysis (RPA) class. PATIENTS AND METHODS From January 1996 to December...

AIM OF THE STUDY To evaluate the feasibility of whole-brain radiotherapy (WBRT) with a simultaneous integrated boost (SIB) by forward intensity-modulated radiation therapy (IMRT) in patients with 1-3 brain metastases. MATERIAL AND METHODS Two forward IMRT plans were implemented among 18 patients. In plan A, the prescribed dose was 30 Gy to the whole brain (PTVWBRT) and 50 Gy to individual bra...

The prognosis is extremely poor for patients with brain metastases in recursive partitioning analysis (RPA) class 3. It is not clear whether dose elevation for brain lesions in addition to whole-brain radiotherapy could improve survival for those patients. This study aimed to assess the efficacy and safety of dose elevation with intensity-modulated radiation therapy (IMRT) for patients with 1 t...

Introduction: Craniospinal radiotherapy is a therapeutic technique for central nervous system (CNS) tumors, which requires meticulous attention to technique and dosimetry.Treatment planning system (TPS) is one of the main equipment in radiotherapy; therefore, the evaluation of its accuracy is essential for dose calculation. The present study evaluates the validity of Isogray TPS in craniospinal...
