Значения термина multilevel sectioning на английском

All sentinel and nonsentinel lymph nodes were evaluated for micrometastases via multilevel sectioning followed by immunohistochemical staining.

In sentinel nodes negative for tumor cells on routine hematoxylin-eosin examination, multilevel sectioning and immunohistochemical staining were performed to search for micrometastases.

Among the remaining 26 patients, multilevel sectioning in conjunction with immunohistochemical analysis identified 5 patients (19%) who had micrometastases in the pelvic lymph nodes.
