Purpose: Fluorine-18 in the development of breast cancer is also used in the regional state assessment, in addition to its use for the detection of remote metastases (PET/BT). Studies that assess both the acillus and the receptive state of the tumor of PET/BT show contradictory results. In this study, it was aimed at studying the effectiveness of PET/BT in assessing both acillus and primary tumor receptor status. Instruments and Methods: 75 patients who were diagnosed with breast cancer between January 2015 and June 2017 were included in the study and PET/BT were studied without neoadjuvan treatment. The patient’s data was retrospective. Patients with distant metastases, non-acillary lymph nod metastases and pre-PET/BT neoadjuvan treatment were dismissed. Results: 75 of the patients in the study had 53 histopathological lymphatic nod metastases, while 22 were not. According to the PET/BT results, 36 patients were positive and 39 were negative. PET/BT’s sensitivity in the accillation assessment was 62.3 percent specificity 86.3 percent accuracy 69.3 percent positive predictive value 91.6 percent and negative predictive value 48.7 percent. There was no significant difference between the Luminal groups in terms of SUVmax. As the positivity of the estrogen and progesterone receptors in the tumor increased, the SUVmax decreased. The result: Despite the high specificity of PET/BT in the assessment of the axility, its sensitivity has not been found at a sufficient level. Also, the SUVmax value of the primary tumor is not enough to predict even if it shows a difference in terms of histological receptors.
