Table 3 The sensitivity of AUS and US-FNAB for detection of nodal metastasis relative to the size of lymph node metastasis
Size of lymph node metastasis | Cases with pN+ | AUS suspicious | AUS sensitivity (%) | p-value | US-FNAB positive | US-FNAB sensitivity (%) | p-value |
|---|---|---|---|---|---|---|---|
≤0.2 mm | 20 | 5 | 25 | 0.000 | 1 | 20 | 0.002 |
> 0.2 mm and ≤2.0 mm | 12 | 3 | 25 | 0 | 0 | ||
> 2.0 mm without extracapsular extension | 14 | 6 | 43 | 3 | 33 | ||
> 2.0 mm with extracapsular extension | 20 | 12 | 60 | 7 | 58 |
