Transanal Endoscopic Microsurgical Excision of pT2 Rectal Cancer: Results and Possible Indications

Abstract

Local R0 resection of low-risk pT2 carcinomas represents an inadequate therapy. In pT2N0M0 rectal carcinomas, the recurrence rate can be reduced through immediate reoperation to a level similar to primary radical surgery. An initial poor local resection result (R1/RX/R < or = 1 mm/G3-4/L1/V1) has no negative influence on further oncologic outcome.
