The preoperative assessment of patients with colorectal cancer (CRC) often requires a multidisciplinary approach, involving a complete endoscopic evaluation as well as both clinical and radiographic staging. In addition to providing a concrete diagnosis, histologic review by the pathologist imparts valuable information about tumor grade and other important prognostic features, which will be discussed in greater detail in this chapter. A thorough history and physical examination rounds out the initial evaluation and provides the surgeon with vital information that may influence operative planning.
