Diagnostic performance of fluorodeoxyglucose-positron emission tomography/computed tomography combined with ultrasonography-guided fine needle aspiration cytology for identifying axillary lymph node status in patients with breast cancer

F-18-fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) scans are positive in any condition which increases metabolism in a mass or tissue and are therefore not specific for neoplastic conditions. The use of an SUV cutoff value of 2.5 may not always help discriminate between benign and malignant cases. For a practicing cytopathologist doing adequacy checks during an image-guided procedure, it may be of value to be aware that elevated SUV values are not always indicative of a malignant process, and vice versa.

Needle Aspiration Cytology

Objective: Ultrasound-guided fine-needle aspiration cytology (USG-FNAC) is used for the detection of axillary lymph node (ALN) metastasis in patients with breast carcinoma (BC). US findings have a good diagnostic accuracy with high sensitivity and specificity. The aim of this study is to correlate the detection of ALN metastases on US with FNAC in BC patients. Study Design: In 75 BC patients, over a period of 9 months (January to September 2017), the size, cortical thickness (CT), presence or absence of hilar fat, and length/width ratio of ALN on US were reviewed and correlated with FNAC findings. Results: The age range was 29–78 (mean 52) years. There were 38 patients with a single ALN and 37 with multiple ALNs. ALNs with a maximum length of > 2.5 cm were malignant in 100% of cases while those ≥1.5 cm were malignant in 80.4%. ALNs with a CT of > 3 mm had metastasis in 78.1% cases. ALNs with absent hilar fat showed tumour in 87.5% cases. A length/width ratio of < 2 showed a metastatic tumour in 66.7% of aspirates. Conclusion: An association was seen between metastatic carcinoma on FNAC and axillary US features of a maximum length of ≥1.5 cm, the absence of hilar fat, and a CT of > 3 mm (p < 0.05).
