In the 28 patients with specimens available for Ki67 staining, the mean SUVmax at baseline and at 10 weeks, and ∆SUVmax did not correlate with the Ki67 index of the tumour tissue before treatment (r = 0.233, p = 0.285; r = −0.321, p = 0.145; and r = −0.191, p = 0.420, respectively). This evidence concerns the gene MKI67 and neoplasm.
