چکیده

The optimal management of patients with few brain metastases is complex. On one hand, stereotactic radiation therapy is a keystone of treatment but is only applicable to highly selected patients fulfilling specific criteria who have access to an adequate radiation unit. On the other, whole-brain radiation therapy may improve survival, but deleterious effects on neurocognitive functions are well known. It has, however, been reported that selected subgroups of patients may benefit from focal dose escalation to brain metastases to prolong survival and the time to intracranial disease progression. Here, we discuss a clinical case to consider the interest of a focal high-dose hypofractionated radiation delivered through a conventional linear accelerator on a large brain metastasis for a patient with metastatic melanoma excluded for stereotactic radiotherapy.

Optimal hypofractionated conformal radiotherapy for large brain metastases in patients with high risk factors: a single-institutional prospective study

BACKGROUND A single-institutional prospective study of optimal hypofractionated conformal radiotherapy for large brain metastases with high risk factors was performed based on the risk prediction of radiation-related complications. METHODS Eighty-eight patients with large brain metastases ≥10 cm(3) in critical areas treated from January 2010 to February 2014 using the CyberKnife were evaluate...

Effect of replacing cochlea contour with inner ear contour on cochlea dose-volume calculations in conventional 2 dimensional and conformal 3 dimensional radiotherapy of brain

Introduction: Sensorineural hearing loss (SNHL) is one of the possible complications of radiotherapy treatment of brain tumors. The auditory system of patients with brain tumors often is placed inside of radiation field and receives a significant amount of radiation dose resulting in hearing loss. The purpose of this study was to compare contouring and delivery dose to cochlea...

Hypofractionated breast cancer radiotherapy. Helical tomotherapy in supine position or classic 3D-conformal radiotherapy in prone position: which is better?

We propose a comparative dosimetric study of whole-breast hypofractionated radiation therapy using helical tomotherapy (HT) in supine position and 3-D conformal radiotherapy (3D-CRT) in prone position. Twelve patients undergoing breast-conserving therapy were retrospectively selected from October to December 2012. Specific dose-volume parameters were selected for the study. The target coverage ...
