Narrative:
I was the flying pilot. During our takeoff roll; at high speed; but prior to V1; I heard the tower controller at mdst airport say our call sign but I did not understand what else they said; the captain responded 'unable' then shortly called V1 and for me to rotate. I performed a normal rotation and takeoff. After we had cleaned up and after completion of the after takeoff check; the captain asked me if I was ok with us having continued the takeoff. I wasn't quite sure what he meant until he explained that the tower controller had cancelled our takeoff clearance late during our departure roll. As we were performing a max thrust; bleeds off takeoff; at the maximum allowable gross weight for that runway; with passengers on board; the captain stated that in the interest of safety; he did not call for a rejected takeoff. As we continued the takeoff; we did not have to perform what would have been a high risk; high speed abort. I agree with his decision. It was the safest thing to do.
