A former cancer researcher at Duke University who had his controversial story aired on "60 Minutes" earlier this month is no longer working for the Myrtle Beach clinic where he moved in the aftermath.

Dr. Anil Potti "is no longer associated" with Coastal Cancer Center of Myrtle Beach, a public relations spokesperson said in an email released today.

Spokesperson Lei Gainer declined to say if Potti was fired or resigned on his own accord. Potti could not be immediately reached, but in the past has not responded to most media inquiries.

His story was featured during a Feb. 12 broadcast of the CBS news show "60 Minutes." The segment, headlined "Deception at Duke," was a continuation of the media and medical scrutiny that drove the oncologist from the school in 2010.

In the report, Potti's cancer investigation claims weren't only described as a failure, but also as possibly "being one of the biggest medical research frauds ever," the program said.
