Retrospective analysis of re-irradiation in malignant glioma: a single-center experience.

Introduction: Malignant gliomas are brain tumors deriving from the brain's glia cells. Primary treatment comprises resection, irradiation and chemotherapy, but these tumors almost always recur. In this situation, palliative chemotherapy is relatively well established, but a second local treatment is sometimes possible.

Recommendations from Gynaecological (GYN) GEC-ESTRO Working Group (I): concepts and terms in 3D image based 3D treatment planning in cervix cancer brachytherapy with emphasis on MRI assessment of GTV and CTV.

Background And Purpose: Brachytherapy (BT) plays a crucial role in the management of invasive cervix cancer from stage I to IV. Intracavitary techniques are based on afterloading devices, with different types of applicators. CT and/or MRI compatible applicators allow a sectional image based approach with a better assessment of gross tumour volume (GTV) and definition and delineation of target volume (CTV) compared to traditional approaches.
