BackgroundThe 'two-week wait'(2WW) referral pathway was introduced in the United Kingdom to reduce waiting times for treatment of cancer. There has been a debate regarding the efficacy of 2WW pathway since its implementation.MethodsA singleinstitutional analysis of upper gastrointestinal(UGI) and lower gastrointestinal(LGI) malignancies treated between 1April 2015 and 31March 2017 was undertaken to analyse the impact of 2WWreferral pathway on the diagnosis, treatment and survival.Results2WW referral does not achieve an earlier diagnosis compared with non-2WW routes of referral in UGI (χ2(3)=2.6, p=0.458) and LGI (χ2(3)=0.884, p=0.829) malignancies. 2WW referral does not lead to an improvement in curative treatment in UGI (OR1.48, 95%CI0.68to3.21, p=0.321) and LGI (OR1.59, 95%CI0.97to2.62, p=0.067) malignancies. No improvement in survival is seen in UGI (HR0.99, 95%CI0.56to1.75, p=0.963) and LGI (HR1.10, 95%CI0.60to1.99, p=0.764) malignancies by virtue of 2WW referral. Emergency presentation is the most common presenting route in UGI malignancy(40%) and is associated with poor survival (HR0.55, 95%CI0.30to0.97, p=0.045).Non-emergency route of presentation is associated with higher rates of curative treatment in UGI malignancies (OR3.49, 95%CI1.57to7.76, p=0.002). Lower rate of curative treatment (OR 0.27, 95%CI0.16to0.43, p<0.001) and poor survival (HR0.44, 95%CI0.26to0.76, p=0.003) is also observed in emergency presentation of LGI malignancy(29%) which is the secondmost common route of presentation in this group.Conclusion2WW referral does not achieve early diagnosis nor does it lead to an improvement in the rate of curative treatment in UGI and LGI malignancies. No improvement in short-term survival is seen in UGI malignancies nor in LGI malignancies on multivariate analysis by virtue of 2WW referral.© Author(s) (or their employer(s)) 2019.
