Background and aim of the guideline:

Aim:

Guideline which is endorsed by many, that does NOT lead to larger

treatment volumes, but DOES lead to uniform delineation in the

various studies

Primarily started with anatomical borders, based on theory.

But, because of excellent local and regional controls: take care not to

increase treatment volumes!

Made compromises, tried to reconstruct: what is the CTV we apparently

have been treating all these years …- does it fit the recurrence rates ?
