Prognostic value of

To investigate the prognostic value of pretreatment fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ( Eighty-three patients who had a tumor larger than 2cm shown by Median overall follow-up was 36.3 months (16.1-76.9 months), during which 11 patients had recurrence and 4 died. Results of receiver operating characteristics curve analysis and log-rank tests showed that high primary tumor SUVmax (≥6.20), MTV (≥5.39), TLG (≥23.23), and total choline peak (≥12.1) values indicated significantly worse RFS as compared to lower values (<6.20, <5.39, <23.23, <12.1, respectively) (P=0.0085, P=0.0029, P=0.013, P=0.016, respectively). The ADC cut-off value (0.833×10 Fluorine-18-FDG PET/CT was superior as compared to MRS and DWI for determining recurrence and death prognostic factors, especially primary tumor SUVmax and TLG, in patients with breast cancer.
