Cases with discordant results between intraoperative pathological diagnosis and OSNA assay.
| Patient no. | Histological type | Lymph node station | IPD/OSNA* | CK19 mRNA (copies/μl) |
|---|---|---|---|---|
| 4 | Sq | 11 (interlobar node) | Negative/micro | 2700 |
| 15 | Ad | 11s (interlobar node) | Negative/micro | < 250** |
| 77 | Ad | 7 (subcarinal node) | Positive/Negative | < 250 |
| 10L (hilar node) | Positive/negative | < 250 | ||
| 94 | Ad | 11 (interlobar node) | Negative/negative | 270 |
Sq, squamous cell carcinoma; Ad, adenocarcinoma; IPD, interoperative pathological diagnosis.
*In the OSNA assay, macro, micro, and negative showed > 5000, 250–5000, and < 250 copies/uL of CK19 mRNA, respectively.
**Micrometastasis detected in diluted sample.
