Hazard function analysis of prognosis after recurrent colorectal cancer

Mean survival time (MST) is used as the indicator of prognosis in patients with a colorectal cancer (CRC) recurrence. The present study aimed to visualize the changes in death risk after a CRC recurrence using hazard function analysis (HFA) to provide an alternative prognostic indicator to MST. The medical records of 725 consecutive patients with a recurrence following R0 radical surgery for CRC were retrospectively reviewed. The five-year, post-recurrence survival rate was 37.8
