From: Outcome of colon cancer initially presenting as colon perforation and obstruction
The survival curves of stage IIIB colon cancer and complicated (with perforation or obstruction) colon cancer are extremely similar. The overall 1-year survival rate was 83.7% and 3-year survival rate was 59.7% in colon cancer with perforation and obstruction. In comparison, the overall 1-year and 3-year survival rates were 83.4 and 59.3%, respectively, in stage IIIB colon cancer. The survival curve of stage IIIB colon cancer was plotted on the basis of the seventh edition of the American Joint committee on Cancer cancer staging manual and the future of TNM
