Saving more sphincters?
Tumor down-staging occurred in 72 (62%) cases
Pathological complete response (CR) in 32 (27%) of patients
In cancers < 6cm from AV, sphincter preservation was
performed in 9 of the 17 (53%) CRs but only 20 of 52
patients (38%) when residual disease present
Impact of RT seems to be for population with probable CCR
