Years later, Arslan et al. also attempted to demonstrate by FDG-PET/CT the association of SUVmax with the coexistence of KRAS mutations in 83 patients with CRC; they found that SUVmax was higher in KRASmt patients than in wild-type patients (24.0+/−9.0 vs. 17.7+/−8.2) [61]. The gene discussed is KRAS; the disease is colorectal carcinoma.
