Alternatively, you can use a local macro to store your 
calculated p-value, which can be plugged directly into
-outreg2-

webuse stan3, clear
stset
stcox age posttran surg yea
local prchi2= 1-chi2(e(df_m),e(chi2))
outreg2 using eraseMe, addstat(prchi2,`prchi2') replace

This is explained in the help file (-help outreg2-) under
"Example 7. Added statistics and notes."

Since this question comes up fairly often, it probably
needs to be made more explicit with better titles 
like "How to report missing p-values".
