I don't think there is a program in Stata that will do this. However
-estat concordance- after -stcox- will estimate a related quantity.
To quote the help:
" estat concordance calculates Harrell's C, which is defined as the
proportion of all usable subject pairs in which the predictions and
outcomes are concordant. estat concordance also reports the Somers' D
rank correlation, which is obtained by calculating 2(C-0.5).
