Abstract

Objective  To explore the application value of the 18F-FDG PET/CT for early prediction of the remission rate and survival of recurrent metastatic non-small cell lung cancer (NSCLC). Methods  A total of 24 patients with recurrent or metastatic NSCLC were selected. All patients underwent the PET/CT examination before and after the first cycle of chemotherapy. The differences of SUVmax1, SUVmax2, ΔSUVmax, and the change rate of SUVmax between the objective response (OR) group and non-objective response (non-OR) group were analyzed, as well as the effect of metabolic response on the overall survival (OS). Results  ΔSUVmax of the OR group (2.415±0.266) was significantly higher than that of the non-OR group (0.854±0.316, P=0.001 7). The change rate of SUVmax of the OR group (31.320±0.723) was remarkably higher than that of the non-OR group (9.909±3.592, P<0.001). The survival analysis showed that the overall survival of the OR group was obviously longer than that of the non-OR group (P<0.05). The overall survival of the metabolic response group was significantly longer than that of the non-metabolic response group (P<0.05). The remission response rates of the metabolic response group and non-metabolic response group were 76.92% and 0%, respectively (χ2=13.901, P<0.001). Conclusion  18F-FDG PET/CT is valuable for early prediction of the remission rate and survival of patients with recurrent or metastatic NSCLC and further clinical study and verification are needed.
