Assessment of CD133, COX-2 and CD8 could be useful in predicting a good response to preoperative CRT in patients with lower rectal cancer undergoing neoadjuvant therapy. Further studies are needed to validate the results in larger cohorts and investigate a survival benefit.
A prospective trial involving patients with only two or three positive findings for treatment using preoperative CRT (study ID: UMIN000026306) is currently ongoing, to obtain more robust findings.

All consecutive patients with stage II-III rectal cancer undergoing long-term preoperative CRT followed by surgery, were included. Preoperative CRT was indicated for patients with cT3-4 low rectal cancer where the distal margin was located below the peritoneal reflection. Forty-nine patients were enrolled prospectively. Between 2011 and 2013, 13 patients received 80 mg/m2 irinotecan (UMIN000011993). However, seven of these 13 patients developed grade III or higher adverse events, such as diarrhoea (3 patients), neutropenia (4) and anorexia (1). Thus, from patient 14 onwards, only S-1 was administered between 2014 and 2017 (UMIN000013486).
Pretreatment biopsies were stained immunohistochemically using antibodies to determine CD133 and COX-2 expression, and increased CD8+ density. Patients were treated with long-term preoperative CRT (45Gy (25 daily doses of 1.8Gy), and S-1 with/without irinotecan), followed by total mesorectal excision.
Forty-nine patients were enrolled prospectively. Between 2011 and 2013, 13 patients received 80 mg/m2 irinotecan (UMIN000011993). However, seven of these 13 patients developed grade III or higher adverse events, such as diarrhoea (3 patients), neutropenia (4) and anorexia (1). Thus, from patient 14 onwards, only S-1 was administered between 2014 and 2017 (UMIN000013486). After the change of regimen, only 3 patients developed grade III adverse events, such as diarrhoea (1), neutropenia (2) .
Outcome measures were tumour regression grade (TRG), tumour downstaging and survival. TRG was assessed semiquantitatively using haematoxylin and eosin-stained slides. Tumour downstaging was defined as pathological findings of ypT0-2, because all cancers had been estimated to be cT3-4 according to inclusion criteria.Local recurrence-free survival was defined as the time from surgery to local recurrence in patients with rectal cancer, whereas relapse-free survival was defined as the time to the first relapse or death from any cause.
