* Data source: SEER, 1983 to 1992 diagnosis period with follow-up through 1995. lx = No. of patients alive at the start of the year; qx = estimated probability of dying in the year given alive at the start; Sx = estimated cumulative probability of survival to the end of the year.

{dagger} Estimate not reported because the standard error of the survival probability was >= 5%.
