Low rectal anastomoses much more frequent for “CRT surg.” (p0.001). APR much more frequent for “NCRT surg.”(p0.001). Local recurrence much more frequent for “NCRT surg.” (p=0.001). Better survival for “CRT surg.” (p=0.005). Surgeons performing ≥ 21 operations in the considered period had better results than those performing 21 (p=0.001). “CRT surg.” with ≥ 21 operations in the considered period had the best results (p=0.005).; 9793 operations for colorectal cancer performed by 812 surgeons in 50 hospitals. Year volume/surgeon: low (5), middle (5-10), high (10). Year volume/hospital: low (40), middle (40-70), high (70). Surgeons with higher volume obtained better results in terms of mortality, hospitalization and costs. Surgeons with “middle volume” obtained results close to “high volume” colleagues if working in “high volume” hospitals.; 378 cases of rectal cancer operated during a 3 years-period by vascul
