![]() Median survival found shorter in DOM patients ( P = 0.030, Log Rank = 0.110). High TLG associated with tumour diameter (TLG 40–70%), high Ki-67 (TLG 40–70%), ALN metastasis (TLG 40%), ALN diameter (TLG 40–70%) and DNM (TLG 40–70%). High MTV associated with tumour diameter (MTV 40–70%), axillary lymph node (ALN) diameter (MTV 40–70%), and distant nodal metastasis (DNM) (MTV 50–70%). There was significant association between molecular subtypes and SUV max ( P = 0.002). Primary tumour 18F-FDG uptake associated increased tumour diameter (>2 cm), high Ki-67 (>15%) and distant organ metastasis (DOM) ( P = 0.015, 0.005 and 0.016, respectively). ![]() Nodal involvement, distant metastasis, ER, PR, Ki-67 expression and survival data evaluated by comparing FDG PET parameters. MTV and TLG (40%, 50%, 60% and 70%) used in conjunction with primary tumour SUV max. MethodsĪ total of 139 metastatic IDC BC who underwent 18F-FDG PET/CT imaging were included to study. ![]() We aimed to investigate the prognostic and clinical values of two volumetric PET parameters used in conjunction with SUV max at different thresholds in invasive ductal carcinoma (IDC).
