Abstract

PML regulates a wide range of pathways involved in tumorigenesis, such as apoptosis, which is also one of the main mechanisms through which oxaliplatin and fluoropyrimidine exert their antineoplastic activity. The present study aims to investigate PML expression as a predictive factor of oxaliplatin/fluoropyrimidine therapy efficacy.EXPERIMENTAL DESIGN:74 metastatic colorectal cancer patients who received oxaliplatin/floropyrimidine-based first line therapy have been included in this retrospective study. PML expression was assessed by immunohistochemistry.RESULTS:PML down-regulation was detected in 39 (52.7%) patients (14 complete and 25 partial PML loss). RR was significantly lower (25.6%) in patients with PML down-regulation than in patients with preserved PML expression (60%) (P = 0.006). Median TTP was 5.5 months when PML was down-regulated versus 11.9 months in case of preserved PML expression (P < 0.0001). A statistical significant difference was also detected in OS (15.6 and 24.5 months respectively, P = 0.003). The impact of PML down-regulation on TTP and OS was statistically significant also in a multivariate model.CONCLUSIONS:This study represents the first evidence of a possible correlation between PML protein expression and outcome of metastatic colorectal cancer patients treated with oxaliplatin/fluoropyrimidine-based first line therapy.
