Expert consensus on re-irradiation for recurrent glioma

Re-irradiation in patients with recurrent glioma has been shown to be feasible in a number of retrospective studies. Re-irradiation may offer palliation of symptoms and  may in some patients also improve outcome.  Guidelines governing patient selection for re-irradiation as well as the volume, dose and fractionation to be employed  are lacking. While trials examining these questions are ongoing, many patients may not meet trial criteria and may nonetheless receive re-irradiation when no other options are available.

This survey will form the backbone of an expert consensus paper on this subject and you are kindly invited to participate. The survey will be distributed to a very limited number of radiation oncologists  who treat central nervous system tumors and have a specific interest in re-irradiation of glioma. The survey is divided into 2 sections.

The first section containing 10 questions is a demographic section and will help assess the load of re-irradiation cases you treat/have treated and ensure that your contact is available such that you may be included on the final publication.

The second and final section contains 5 re-irradiation cases with 5 to 6 questions associated with each case.

A comment section is available following each case. Any comments you may have with respect to the cases or the questions  themselves would be very welcome and will help strengthen the understanding of how radiation oncologists approach these challenging scenarios and ultimately decide on management.

Thank you in advance for your opinion and for taking the time to answer these questions.
