Patient records were manually reviewed. Chi-square, Fisher's exact test Mann Whitney U-test used as appropriate. Kaplan-Meier Cox proportional hazards regression modelling analysis.1667 included (360 NBSP 1307 non-NBSP). 863 (51.8%) male. Median age diagnosis 73 years (range 21-100); younger (median 68 vs. 76 years, P < 0.001). had significantly lower T, N, M overall TNM stage than non-BSP patients. estimate on analysis 94 months Statistically significant (P 0.05) predictors mortality multi-variate increasing compared I (stage II HR 1.63 (95% CI 1.14-2.34), III 2.86 2.03-4.03), IV 7.73 5.59-10.68)), within (HR 0.51 0.37-0.71)), 1.03 1.02-1.03)), urgent/emergency surgery 1.66 1.36-2.01)) formal resection primary tumour 0.31 0.25-0.38)).Patients diagnosed found to be have earlier CRC.
