Those patients who achieved a complete clinical response were offered a nonoperative management strategy and the remaining patients underwent surgical resection. The primary endpoint was tumor regression grade (TRG) based on radiological imaging (mrTRG) or pathology (pTRG). Patient response was classified as good (mrTRG 1\u20132 or pTRG 0\u20131) versus poor (mrTRG 3\u20134 or pTRG 2\u20133).
