Prognostic value of thoracic FDG PET imaging after treatment for XXXX .

@entity1 @entity1149 @entity2 @entity419
OBJECTIVE: We determined the prognostic value of @entity419 (FDG) positron emission tomography (PET) for @entity1 with treated @entity2 . MATERIALS AND METHODS: We examined @entity1 who underwent FDG PET after first-line treatment for @entity1149 . FDG PET results were correlated with survival rates to determine whether FDG PET findings were predictive of outcomes. RESULTS: After initial therapy, 113 @entity1 with @entity1149 underwent FDG PET. One hundred @entity1 had positive FDG PET results and a median survival of 12 months (95% confidence interval, 9.2-15.4). Thirteen @entity1 had negative FDG PET results, and 11 (85%) of these @entity1 are still living at a median follow-up of 34 months. The difference in survival for @entity1 with positive and negative FDG PET results was statistically significant (p = 0.002). CONCLUSION: FDG PET has prognostic value and strongly correlates with survival rates of @entity1 with treated @entity2 . @entity1 with positive FDG PET results have a significantly worse prognosis than @entity1 with negative results. Additionally, FDG PET may be helpful in guiding therapeutic treatments.
