e14610 Background: Preclinical and retrospective studies suggested antitumor activity for the incidental use of betablockers in various tumour types. Data regarding colorectal cancer are lacking. We assessed the correlation between the incidental use of betablockers and clinical outcome in colorectal cancer patients receiving first-line therapy. Methods: 235 patients treated with first-line chemotherapy alone (128 patients) and with Bevacizumab (107 patients) were analysed. Patients were stratified for betablockers use, age, sex, site of metastases, previous adjuvant chemotherapy and ECOG performance status. Results: 29 patients (12%) were on treatment with betablockers at the time of first-line therapy: 20 (16%) in the chemotherapy alone group and 9 in the bevacizumab group (8%). In both groups patients receiving or not betablockers were similar for all main clinical characteristics. In the chemotherapy alone group, patients receiving betablockers showed an improved response rate (60% vs. 33%, p=0.044) and overall survival (mOS 41.3 vs 25.7 months, p=0.03, HR:2.26, 95% CI: 1.05-3.24). Only a trend for improved progression free survival was noticed. In the 107 patients receiving chemotherapy with bevacizumab a trend towards a worse overall survival was seen for patients receiving betablockers, although this was not statistically significant (mOS 16 vs 23.7 months, p=0.26, HR:0.64, 95% CI: 0.22-1.49). No significant differences were seen in regards of progression free survival or different response rate patterns between the two groups. Conclusions: Our analysis confirms a potential prognostic role for the use of betablockers in colorectal cancer patients treated with chemotherapy. Our findings are in line with preclinical studies suggesting that beta-adrenergic signalling may regulate cancerogenesis and tumor invasiveness. Our analysis suggests a potential worse outcome for patients on betablockers receiving Bevacizumab-based treatment, although the small number of patients precludes any definitive conclusion. We suggest that in future prospective trials the incidental use of betablockers will be considered a stratification factor for clinical outcome.
