Time to diagnosis and stage of symptomatic colorectal cancer determined by three different sources of information: A population based retrospective study
Conclusion There is no evidence that patients with more advanced CRC have longer TDIs. In fact, we found an inverse relationship between the TDI and CRC stage, an example of the “waiting time paradox”. This association may likely be due to the presence of unmeasured confounders as the stage when symptoms appear or the tumour aggressiveness.
