Bowel Cancer survival statistics

This page presents bowel cancer survival statistics including one and five year survival, by age at diagnosis, and by stage. There have been similar and significant improvements in survival for both colon and rectal cancer over the last 25 years. 1

Bowel cancer - one and five year survival rates

The five-year relative survival rates for both male and female colon and rectal cancer have doubled between the early 1970s and early 2000. 2-4 Five-year relative survival for male colon cancer rose from 22% in the early 1970s to 52% in early 2000 for females it rose from 23% to 53%.

Five-year survival rates for male rectal cancer rose from 25% in the early 1970s to 50% in early 2000 and from 27% to 52% for female rectal cancer. These improvements are a result of earlier diagnosis and better treatment but there is still much scope for further progress.

The rises in one and five-year age-standardised relative survival rates for colon cancer are shown in Figure 3.1. 1

The rises in one and five-year age-standardised relative survival rates for rectal cancer are shown in Figure 3.2. 1

Ten-year survival rates are only a little lower than those at five-years indicating that most patients who survive for five years are cured from this disease. 4

Bowel cancer - survival rates by age at diagnosis

Younger patients have a better prognosis than older patients as the rates in Figure 3.3 show. 1

Bowel cancer - survival rates by stage at diagnosis

Patients who are diagnosed at an early stage have a much better prognosis than those who present with more extensive disease (Table 3.1). 5 Over 93% of patients diagnosed with Dukes stage A (the earliest stage of the disease) survived five years compared with only 7% of patients with advanced disease (Dukes D).

There is also an advantage of between 5% and 9% in five-year relative survival for the most affluent patients compared with the most deprived groups. 1 If this deprivation difference was removed so that all groups had the highest survival, then over 2,000 deaths would be avoided in the five years following diagnosis. 6

Comparison of bowel cancer survival rates across Europe shows significant inter-country differences. 7 It has been suggested that the poorer survival in the UK compared with the rest of western Europe relates to late presentation or delay in treatment, 8 but caution needs to be exercised in interpreting these variations. 9 However, the existence of differences in survival over time and place suggest that there are ways in which the prognosis could be improved in countries such as the UK.
