Purpose Neoadjuvant chemoradiotherapy (CRT) improves local control in locally advanced rectal cancer (LARC) but has not consistently demonstrated a survival benefit. This study evaluated whether pathological complete response (ypCR) after CRT confers systemic oncological benefit beyond local tumor control. Methods A to...
