CHICAGO ( TheStreet) --The American Society of Clinical Oncology (ASCO) annual meeting gets underway in earnest today. For Wall Street, the most newsworthy data presentations Saturday will come from Arqule ( ARQL - Get Report), Delcath Systems ( DCTH), Amgen ( AMGN - Get Report) and Celldex Therapeutics ( CLDX - Get Report). ASCO itself is holding two media briefings this morning focusing on new research into lung cancer and novel therapeutics against cancer. Later tonight, Exelixis ( EXEL) and Dendreon ( DNDN) are holding off-site investor meetings. Follow this live blog throughout the day for continuous updates and reports from the ASCO meeting. I'll be reporting on clinical data presentations as I see and hear them, and I'll be blogging from the hallways, exhibition hall and meeting rooms, giving you a real-time perspective on all the investor-worthy buzz. With my iPhone and some nifty software, I'll even try to bring you photos and audio for an even deeper perspective. I welcome your comments and questions on this live blog, too, which I'll do my best to answer and publish as time permits. You can also follow my ASCO 2010 coverage on Twitter.
