OBJECTIVE: This study aimed to evaluate the prognostic value of F-18 FDG PET/CT in comparison with Tc-99m sestamibi breast-specific gamma imaging (BSGI) and previously established clinical prognostic parameters of invasive ductal breast carcinoma (IDC).
METHODS: We retrospectively included 157 female IDC patients (mean age 49.2 years, range 29.9-78.9) who underwent PET/CT and BSGI. The maximum standardized uptake value (SUVmax) and tumor to normal background ratios (TNRs) of their primary tumors were measured on PET/CT and BSGI, respectively. Univariate and multivariate survival analyses were performed to evaluate the prognostic value of the measured parameters and other clinical prognostic factors: age, menopausal status, breast density, pathologic tumor size (pTS), axillary nodal status (ANS), nuclear grade, histologic grade, hormone receptor status of estrogen (ER) and progesterone receptors (PR) and HER-2 expression.
RESULTS: Among 157 patients, recurrences occurred in 22 patients (14.0 %). In univariate analyses, pTS (p < 0.0001), ANS (p < 0.0001), nuclear grade (p = 0.0046), histologic grade (p = 0.0001), ER status (p < 0.0001), PR status (p = 0.0037), HER-2 status (p = 0.0007), primary tumor SUVmax (p < 0.0001) and TNR (p = 0.0001) were significant predictors of recurrence. Among them, pTS (p = 0.0172), ANS (p = 0.0416), ER status (p = 0.0375) and primary tumor SUVmax (p = 0.0239) were independent prognostic factors in multivariate regression analysis.
CONCLUSIONS: High primary tumor SUVmax of PET/CT and high TNR of BSGI were poor prognostic factors in IDC patients; in addition, primary tumor SUVmax was an independent prognostic factor along with pTS, ANS and ER status.
