Abstract
Breast lumps are one of the commonest complaints encountered in surgical OPD's. that makes it important to differentiate between benign and malignant conditions before treatment. Our study is an endeavour to find out the accuracy of Trucut biopsy for diagnosis breast lump compared to regular FNAC’s.
Materials and methods
55 patients with palpable breast lumps were taken up for this study and subjected to Trucut biopsy and FNAC. Reports were compared with histopathology of the exised lump/mastectomy specimen. Results: Percent positivity of malignant diagnosis on Trucut biopsy (B5) was 38.18% while that on FNAC (C5) was 25.45%. Thus Trucut biopsy detected 12.73% more malignant cases than FNAC. The suspicious rates for FNAC (C3&C4) expressed as a percentage of the total number of cases was 36.35% compared to the suspicious rate of Trucut biopsy (B3&B4) of just 1.81%. Percentage of benign cases diagnosed on FNAC (C2) was 34.54 while that on Trucut biopsy (B2) was 52.72. Thus there was a 18.18% increase in definitive benign diagnosis by Trucut biopsy over FNAC.
Conclusion: Trucut biopsy detected more breast carcinomas as compared FNAC with a sensitivity of 95.45% as opposed to 63.63%. Though both the techniques were equally specific, Trucut biopsy was able to correctly categorize borderline / inadequate lesions into definitely benign and malignant categories.
