Recently a meta-analysis study comparing Ki67 index from biopsies of 1213 lung cancer patients to [18F]-FDG or [18F]-FLT standard uptake values revealed respective pooled Rho values of 0.45 and 0.65, indicating higher reliability for [18F]-FLT to assess lung cancer cell proliferation [12]. Here, MKI67 is linked to lung carcinoma.
