TAE for T1 Rectal Cancer 1. High risk of ca recurrence vs. RAD. 2. TAE has a lower cancer cure rate. 3. Neither adjuvant therapy nor surgical salvage are reliable. Paty P et al Ann Surg 2002 Bentran D et al Ann Surg , 2005 Nash, G DCR, 2008
Survival outcome of local excision versus radical resection of colon or rectal carcinoma: a surveillance, epidemiology, and end results (SEER) population-based study • N = 13,262 pts with rectal cancer • Surgery • 3715 (28%) local excision • 9547 (72%) major resection • Preoperative clinical T staging • 953 (7%) Tis • 6223 (47%) T1 • 6086 (46%) T2 Bhangu A et al.

Local excision in early rectal cancer – outcome worse than expected: a population based study • N = 3694 consecutive stage I rectal ca pts from Swedish Rectal Cancer Register • 448 LE vs 3246 radical resection (Hartmann, LAR, APR) • LE pts • LR 11.2% (vs ~3% for all radical procedures combined) • Relative survival 0.81 (95% CI 0.75-0.88) Saraste D et al.

Multimodality salvage of recurrent disease after local excision for rectal cancer 5y OS s/p salvage 63% 3y RFS s/p salvage 43% In salvage surgery R0 resection in 80%, Multivisceral 30%, neoadjuvant 70% Sphincter preservation in 33% You YN et al. Dis Colon Rectum. 2012.

Preoperative Considerations if Pursuing a Sphincter Preserving Resection Determination is both preop and intraop Body habitus, sphincter mass? Sphincter tone, squeeze? Co-morbidities? Patient expectations, enthusiasm? Understands the “good news/bad news” post operative scenario.
As in fly fishing…“Match the Hatch” “Match the Disease” Should be the governing paradigm in the management of rectal cancer J Guillem, Ann Surg 2007
