Abstract P2-01-16: Role of 18 FDG PET/CT in axillary staging in early breast cancer

OBJETIVE To evaluate the 18F-FDG PET/CT capacity for the detection of axillary metastases and compare results with sentinel lymph node biopsy (SLNB).MATERIAL AND METHODS: 99 female patients with clinical T1T2N0 breast cancer were included. Patients with recent breast or axillary surgery, T3T4 disease, ductal carcinoma in situ, inflammatory carcinoma, uncontrolled diabetes mellitus and pregnant or lactation patients were excluded. Pre-operative FDG PET-CT was performed 15 days before surgery, SLNB took place with the combined method (radioisotopes and patent blue). Pearson and Spearman correlation test were used to evaluate association of main variables with a significance level (p) of 0.05.RESULTS: Breast PET-CT results: 80 positive PET/CT. Negative PET/ CT in 19 patients (4invasive lobular carcinoma, 7 tumors Citation Format: Cristina Noblia, Eugenia Azar, Dolores Mansilla, Amilcar Osorio, Eduardo Armanasco, Diana Montoya, Martin Ipina, Gaston Berman, Eduardo Gonzalez, Christian Gonzalez, Gabriel Bruno, Patricia Parma, Carla Pulero, Ana Alvarez.
