Question 47: What Do I Tell A Patient Who I Just Diagnosed With Stage Iib Colon Cancer Regarding Treatment And Prognosis? (continued)

Scott L. Itzkowitz, DO, FACP

Long-term treatment recommendations and prognosis of colon cancer are based on tumor stage at the time of initial diagnosis. Based on the TNM staging system, stage IIB cancer is any cancer considered T4 (tumor invades other organs or structures and/or perforates the visceral peritoneum) (Figure 47-1) without nodal or distant metastases (N0, M0). While initial clinical staging can be done through radiographic, endoscopic, and/or intraoperative means, pathologic staging serves as the basis for estimated survival rates. The current 5-year survival rate for stage IIB colon cancer is 72%.
