Declarations
:
: We have to provide complete informed consent for every patient before he or she will undergo cancer treatment in our hospital. There was an appropriate waiver of IRB for this retrospective analysis. The IRB exempted us from the informed consent for patients’ participation in this study because our study was retrospective design for their survival data. Patients’ clinical and pathology data were collected prospectively into the tumor registry of division of colon and rectal surgery when patients received colorectal cancer treatment. We applied for the appropriate ethics approval for tumor registry and obtained it from the Institutional Review Board (IRB) of Chang Gung Memorial Hospital. The further follow-up data for survival were collected retrospectively according to medical record or interview.
