High SLPI expression in chemotherapy-treated stage III MSS CRC patients is associated with increased disease-free survival. Kaplan–Meier curves for disease-free survival after resection of the primary tumor (in months) for stage II and stage III CRC patients with MSS tumors not treated with adjuvant chemotherapy (a) or treated with adjuvant chemotherapy (b) stratified by SLPI expression detected using the monoclonal antibody. Kaplan–Meier curves for disease-free survival after resection of the primary tumor (in months) for stage III CRC patients with MSS tumors not treated with adjuvant chemotherapy (c) or treated with adjuvant chemotherapy (d) stratified by SLPI expression detected using the monoclonal antibody. Curves with the validated cut-off are shown. P-values were calculated using the log-rank test. MSS micro-satellite stable.
