Core tip: Strictly speaking, there is no common objective guideline to predict prognosis and give adjuvant treatment according to risk stratification. Patients who show good response were thought to have good prognosis. However, expected value of recurrence-free survival or recurrence rate was not suggested especially in patients who did not show good response to patients receiving preoperative chemoradiotherapy (PCRT). In addition, how to measure the response level was variable. The present study suggests impression of prognosis based on pathologic stage, which is objective, after PCRT and radical resection and show stage-by-stage comparison with those without PCRT to give impression of prognosis by using familiar stage-based prognosis.
