Because of the high frequency of tumoral recurrence in colorectal cancer, studies capable of determining the degree of dissemination (ultrasonography, computerized axial tomography, nuclear magnetic resonance imaging) are performed when evaluating the therapeutic possibilities of surgery. Positron emission tomography (PET) allows better staging of the extension of metastatic recurrence, as demonstrated in the two cases presented herein: one with a second recurrence in the mesenteric node and another with recurrence exclusively in the liver. In both cases the technique enabled radical resection of the tumoral recurrence. The impact of PET on the results of rescue surgery in colorectal cancer remains to be determined.
