In a Swiss study of 915 patients with 376 rectal and 539 colonic primaries both the surgeon's and hospital's annual caseloads were independent, beneficial prognostic factors for overall survival (P = .0003, P = .044), disease free survival (P = .0008, P = .020), and marginally significant factors for local recurrence (P = .057, P = .055) [ 51 ].
