Comparison of 18F-FDG PET/CT and 111In pentetreotide scan for detection of Merkel cell carcinoma
Carcinoma, Merkel Cell
Tomography, X-Ray Computed
Our data on a small number of patients are in agreement with prior individual FDG or OCT reports and suggest that, overall, FDG PET/CT detects more MCC lesions and upgrades MCC stage compared with the OCT scan. Importantly, there were no lesions identified by OCT that were missed by PET. Thus, given the added resolution and sensitivity of PET, the use of OCT in MCC in the modern era is of limited value and it remains to be seen whether newer 68Ga-labeled somatostatin analogs will perform better than OCT.
