Introduction: pathlogy and staging
Staging of colorectal cancer refers to the classification of the tumour according to the extent of spread in a manner that has a clinically useful correlation with prognosis.
Applications of staging include patient management, quality assurance and research.
A number of imaging techniques, including CT scan, MRI, PET scanning, and endorectal ultrasound, can be used to define the extent of tumour spread before treatment (see Imaging for colon cancer and Imaging for rectal cancer). There is, however, no known, reliable, preoperative staging system that correlates accurately with patient survival.
