Current pattern of care in radiation therapy for DCIS in Australia and New Zealand - where are we heading?

BCS is the preferred surgical management of DCIS in ANZ. Currently RT is omitted following BCS in 25 % of cases. Using LRCC and RTOG 9804 low risk classifiers there was inconsistent avoidance of RT, whereas RT was avoided in 15.9 % of higher risk patients. More consistent and transparent selection methods are desirable and currently genomic testing and clinico-molecular tools appears promising.
