Recent comments on RTOG atlases
(& probably also valid for ESTRO atlas):
• In case of massive involvement supraclavicular
nodes: nodes extend beyond CTVn_L4
should
atlas be adapted ?
(
Brown et al, IJRBOP 2015; Jing et al IJRBOP 2015)
• To cover 95% of lymph nodes at cranial and
anterior borders of level 1, CTVn_L1 should be
increased considerably: i.e. take into account nodal
involvement seen before surgery/ chemotherapy
(Gentile et al, IJRBOP 2015).
•
NB: ESTRO guidelines are meant for elective
irradiation of early stage breast cancer; i.e. in case
of clinically overt pathological nodes: individualise
target volume delineation !
