Neoadjuvant TherapyProblems with Current Practice
CRT 55 Weeks 6 wks TME

18 weeksbull Delayedbull Reducedbull Omitted
CRT TME Neodjuvant Chemoth
Neodjuvant Chemoth CRT TME
bull Total Neoadjuvant Therapy Paradigm
bull Better down-staging
bull Better pCR
bull Higher R 0 Resection Rates
Adopted from Deborah Schragrsquos Presentation at 2015 ASCO Annual Meeting
The Art of Today
bull Radical resection remains the cornerstone in management regardless the achieved response
bull The identification of patients with pCR is challenging however patients should be informed about watch and wait strategy
bull Data showed higher incidence of relapse during the 1st year then becoming comparable to those following radical surgery intensive follow up during the 1st year
bull Adoption of MDT should be encouragedbull The need for more clinical trials is highly appreciated
