Cytological and Pathological Correlation of FNAC in Assessing Breast Lumps and Axillary Lymph Node Swellings in a Public Sector Hospital in India

الملخص EN

Background.

Breast lumps have varied pathology, and there are different techniques to prove the diagnosis.

The aim of the present study is to analyze the role of fine needle aspiration cytology (FNAC) of the breast lesions at our center.

Methods.

We had retrospectively analysed 854 patients who underwent FNAC for primary breast lumps and 190 patients who underwent FNAC for an axillary lymph node in the year 2010.

Results.

Of 854 patients, histological correlation was available in 723 patients.

The analysis was done for 812 patients as medical records were not available for 42 patients.

FNAC was false negative in seven cases; 2 cases of phyllodes were reported as fibroadenoma, and 5 cases of carcinoma were diagnosed as atypical hyperplasia.

The sensitivity, specificity, and false negative value of FNAC in diagnosing breast lumps were 99% (715/723), 100%, and 1%, respectively.

Of 190 patients for whom FNAC was performed for axilla, 170 had proven to have axillary lymph node metastases, and the rest had reactive hyperplasia or inflammatory cells.

Conclusions.

FNAC is rapid, accurate, outpatient based, and less complicated procedure and helps in diagnosis of breast cancer, benign diseases, and axillary involvement in experienced hands with less chance of false results.
