With the data I am using, variables A and B have 
values of 0/1. The following KM graph:
 
sts graph if stage==5, by(A B) lpattern(-) xtitle("Survival time in months") l2title("Percent surviving") xmtick(0(10)150)
 
shows a plot in which the lines for the four different 
A/B combinations show in green, brown, blue dash 
and black, but without any command from me.
 
Is it possible to specify that each A/B combination 
have a specific line pattern and color?

If you want lines to differ in pattern rather than color,
you might benefit from the unofficial -lean- schemes which
give plain black-and-white graphs:
 
   findit lean scheme
 
Otherwise you can:
 
   sysuse cancer
   stset studytime, failure(died==1)
   sts graph, by(drug) ///
      plot1opts(lpattern(l) lcolor(black)) ///
      plot2opts(lpattern(-) lcolor(black)) ///
      plot3opts(lpattern(dot) lcolor(black))
 
Hope this helps
