Hippocampal sparing for brain tumor radiotherapy: A retrospective study comparing intensity-modulated radiotherapy and volumetric-modulated arc therapy.

Context: Radiotherapy may have side effects on the brain, such as radiation necrosis, cognitive impairment, and a high chance of tumor recurrence, which has been considered the most common cause of treatment failure.

Aims: Using intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) techniques, we aimed to test the potential outcome of sparing the contralateral hippocampus (CLH) in radiotherapy for brain tumors by comparing dosimetric parameters.

Settings And Design: A prospective clinical comparative study.

Prognostic factors and clinical course of extremity soft-tissue sarcomas.

Purpose: Although soft tissue constitutes half of the body weight, soft-tissue sarcomas (STSs) are less common than any other types of tumors.

Materials And Methods: In this retrospective study, the prognostic factors and clinical courses of 64 patients with extremity STSs treated at our clinic between 1996 and 2012 were investigated.

Results: Of the 64 patients included in this study, 35 (55%) were male and 29 (45%) were female.
