Help!!!! Need form results to go to specific e-mail addresses dependent upon clinical trial

I have a PHP form that submits applications for clinical trials here:  However, each trial needs to get routed to a different e-mail address depending upon the type of cancer the clinical trial is for.  What's the easiest way to accomplish this?
