PET Scans Clear Hurdle for Merkel Cell Dx

November 2, 2012

Use of fluorodeoxyglucose positron emission tomography (FDG-PET) imaging has an impact on how Merkel cell carcinoma patients are diagnosed or treated in about a third of cases, researchers said here.

In fact, 64 of 194 scans (33%) performed on 123 consecutive patients with Merkel cell carcinoma had a 'high' impact -- defined as a change in treatment or treatment plans -- on care, Michael MacManus, MD, of the Peter MacCallum Cancer Centre in Melbourne, Australia, reported at the American Society of Radiation Oncology meeting.
