Purpose: The recent surge in breast carcinoma patients is reported in a variety of statistics. Breast cancer occurs mainly from duct and lobulus: 85% is from the breast ducts. The present study is aimed to distinguish the difference in SUVₘₐₓ changing over time by identifying the type of cancers attacking from the duct. Materials and Methods: The subjects of the study are 291 female breast cancer patients who have visited the present PET/CT center from July 1, 2012 to July 23, 2013. Based on the pathological results, 248 IDC (invasive ductal carcinoma) patients and 43 DCIS (ductal carcinoma in situ) patients were selected. In the same manner as the general PET/CT scan (3.7 MBq/Kg), F-FDG was injected, followed by the primary test (Routine tests) after 1 hr, and the secondary test (Delay test) after another hr. SUVₘₐₓ was measured after setting ROI in the lesion based on the data from the two tests. Results: As the comparative result of the change in the lesion SUVₘₐₓ between the two groups, IDC group's SUVₘₐₓ showed M=7.11 and SD=5.405 in the primary test and increased M=7.11 and SD=5.405 in the secondary test (P<0.05); DCIS group's SUVₘₐₓ showed M=2.739, SD=1.229 in the primary test and increased M=2.614, SD=1.470 in the secondary test (P<0.05). Conclusion: As the comparative result of SUVₘₐₓ over time between the groups, IDC showed increased SUVₘₐₓ in the secondary test (Delay test) compared to the primary test (Routine test) (P=0.000); DCIS showed decreased SUVₘₐₓ in the secondary test (Delay test) compared to the primary test (Routine test) (P=0.039). It was confirmed through this study that the change in SUVₘₐₓ has occurred over time by the type of breast cancer (IDC or DCIS) occurring from the breast ducts. However, the onset of breast cancers (ILC, LCIS) from the lobulus was not discussed due to the lack of samples. Future research on the breast cancers from the lobulus is suggested.
