Metabolic activity measured by FDG PET predicts pathological response in locally advanced superior sulcus NSCLC

In NSCLC patients treated with chemoradiotherapy, changes in SUVmax, SUVTTL, SUVpeak, and SUVPTL were predictive for pathological response (grade 2b/3 and for SUVTTL and SUVPTL grade 3 as well). Postinduction SUVPTL correlated with residual tumor cells.
