TABLE 4.

Yearly Observed and Relative Survival Rates for MDC

Yearly
[-2pt] Survival
Rate		 Observed
Survival		 Relative
Survival		 Standard Error
for Relative
Survival		 95% CI
Upper Lower
1–yr 84.10% 85.80% 3.60% 76.9% 91.40%
3–yr* 73.20% 77.4% 4.6% 66.7% 85.0%
5–yr* 68.50% 75.8% 4.8% 64.9% 83.8%

The survival rates were derived by the SEER* Stat software by an actuarial method (n = 109) from the SEER 17 registry, with no adjustment for heterogeneity.

*

The values for relative survival rates, their standard errors and confidence intervals have been adjusted for increase in cumulative rates from the prior interval.

MDC indicates Meckel diverticulum cancer; CI, confidence interval.
