Abstract:
Objective:To evaluate the diagnostic value of 18G and 16G needle biopsy of breast lesions.Methods: Onr hundred and fifteen patients with breast lesions those were excised through surgery. Each lesion was under ultrasound-guided needle biopsy(US-CNB) with 18G and 16G, then underwent surgical resection of mass and pathological histology. Histological findings of US-CNB and the surgical specimens were analyzed for sensitivities, false negative rates, and underestimate rates.Results: Among 84 cases of breast cancer proved by surgical pathology, the sensitivity, specificity, false negative rate of 18G and 16G biopsy diagnosis were followed by 95.2% and 97.6%, 89.6% and 94.3%, 4.8% and 2.4%. Paired chi-square test showed no significant difference between the two methods.Conclusion: 18G and 16G needle biopsy has no significant difference in the diagnosis of breast lesions.
