Role of ultrasonography to detect axillary node involvement in operable breast cancer

Prompted by the concern about unnecessary axillary dissections, we prospectively studied the accuracy of clinical examination (CE) and conventional ultrasonography (USG, 7.5 MHz), to diagnose pre-operatively metastatic axillary lymph nodes in 200 operable breast cancer patients. USG had higher speci...

Description
Summary:Prompted by the concern about unnecessary axillary dissections, we prospectively studied the accuracy of clinical examination (CE) and conventional ultrasonography (USG, 7.5 MHz), to diagnose pre-operatively metastatic axillary lymph nodes in 200 operable breast cancer patients. USG had higher specificity (90% vs 77%, P=0.025) and higher positive predictive value (ppv=90% vs 76%, P=0.02) than CE. Together, CE + USG had higher sensitivity (82% vs 58%, P=0.00005) and higher negative predictive value (npv = 76% vs 58%, P=0.008) than CE alone. In women 1 positive node were 97% (for both) in women
