Abstract |
For rapid intraoperative diagnosis of lymph node micrometastasis, we refined the rapid immunohistochemistry method by combining anti- cytokeratin antibody-labeled nanocrystal beads with rapid hematoxylin and eosin (H&E) staining on the same section, referred to as the rapid double staining (RDS) technique. Two frozen-section slices each were obtained from 372 lymph nodes of 100 breast cancer patients. We performed RDS for 1 slide and rapid H&E staining for the other. The results were compared with the corresponding final pathological data obtained from the permanent specimens. For specimens from patients with pN1(mi) as determined by final pathological examination, the false‑negative rate was 33.3% for rapid H&E staining and 16.7% for RDS. For specimens from patients with pN0(i+) as determined by final pathological examination, the false‑negative rate was 80% for rapid H&E staining and 0% for RDS. These results indicate that RDS is superior to conventional rapid H&E staining for intraoperative diagnosis of nodal micrometastasis and isolated tumor cells.
