Figure 1 A case of clinical complete response confirmed at pathology. A-C: A 61-year-old male patient with rectal cancer. Endoscopy (A) and magnetic resonance imaging (MRI) (B and C) findings staged a tumour of the low rectum (cT3aN1, mesorectal fascia negative, extramural venous invasion negative, pelvic nodes negative). The patient underwent neoadjuvant chemoradiotherapy; D-G: Restaging at 15 wk after the beginning of the neoadjuvant chemoradiotherapy showed a clinical complete response at endoscopy (D), MRI (E), endorectal ultrasound (F), and 18-fluorodeoxyglucose-computed tomography/positron emission tomography (G).
