Sadly, no there's nothing that can be done. This is why we always recommend you back up your save.

You can ask your fellow forum members for a save file around the same point you were at to continue the storyline, but it won't be your game. You can start a new game as well, but as for your old file, nothing can be done. 
That might not be a corrupt save file though.
