Popis: To identify the correlations between theWe assessed the correlations between the maximum standardized uptake value (SUVmax) of primary tumors as reflected on preoperative FDG-PET images, the pathological features, and cancer recurrence in 124 patients with locally advanced ESCC, who were treated with NAC and esophagectomy.The pre-NAC SUVmax significantly differed for the ypT status and venous invasion (VI). The post-NAC SUVmax (post-SUVmax) significantly differed for the ypT and ypN status, VI, lymphatic invasion (LI), pathological tumor response, down-staging, and recurrence. The decrease in SUVmax before and after NAC (ΔSUVmax) significantly differed for ypT status, LI, VI, pathological tumor response, down-staging, and recurrence. The survivals were significantly stratified according to the optimal cutoffs of SUVmax for predicting recurrence (post- and ΔSUVmax cutoffs: 4.2 and 30, respectively; all p0.0001). Moreover, multivariate analysis showed that the post- and ΔSUVmax were independent predictive factors for recurrence-free survival.The SUVmax on preoperative FDG-PET can predict the degree of aggressiveness of the tumor in locally advanced ESCC treated with NAC.
