The potential benefit of adjuvant chemotherapy in locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy is not predicted by tumor regression grade

Prospective randomized trials with larger populations are needed to identify factors that predict which patients may benefit from the administration of ACT.
