Maximum standard uptake value of 18F-fluorodeoxyglucose positron emission tomography is a prognostic factor for progression-free survival of newly diagnosed patients with diffuse large B cell lymphoma.
The treatment of patients with diffuse large B cell lymphoma (DLBCL) would be greatly facilitated with a rapid method for determining prognosis that can be performed more easily and earlier than cytological or specific pathological examinations. It has been suggested that newly diagnosed patients with DLBCL who have low maximum standard uptake value (SUV(max)) on (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) are more likely to be successfully treated and remain in remission compared with patients with high SUV(max), but this concept has been poorly studied. We retrospectively analyzed 50 patients with de novo DLBCL to evaluate the relationship between the SUV(max) and disease progression. For patients with low SUV(max) (n = 10) and high SUV(max) (n = 40) (P = 0.255), respectively, the 3-year overall survival rates were 90 and 72 %, and the progression-free survival (PFS) rates were 90 and 39 % (P = 0.012). By multivariate analysis, the revised International Prognostics Index (R-IPI) and SUV(max) at diagnosis were shown to predict longer PFS. The 3-year PFS for patients with low SUV(max) classified into the good prognosis group by R-IPI was 100 vs. 62 % for those with high SUV(max) (P = 0.161), and patients with low SUV(max) classified into the poor prognosis group by R-IPI was 80 vs. 18 % for those with high SUV(max) (P = 0.050). We conclude that the SUV(max) on FDG-PET for newly diagnosed patients with DLBCL is an important predictor of disease progression, especially for patients with poor prognosis by R-IPI.
