Weiser et al developed 3 nomograms for predicting survival for a patient following curative colectomy for colon cancer. The authors are from Memorial Sloan-Kettering Cancer Center, Cleveland Clinic and Dana-Farber Cancer Center.
Patient selection: resectable colon cancer (not Stage IV)
Parameters:
(1) T stage
(2) age in years
(3) gender
(4) histologic grade
(5) number of nodes identified
(6) number of lymph nodes positive for malignancy
