Objective: Previous studies considered the presence of micrometastases (MM) in pelvic lymph nodes as clinically relevant prognostic indicator. Method: Frozen section analysis was performed in all cases. After FS-examination nodes were examined by one H&E-stained slide. All nodes without metastatic disease after frozen section and permanent section examination were subject of the present study. 43 patients and 418 PAN were enrolled and immunohistochemical staining using two cytokeratin-cocktail antibodies (AE 1/AE 3 and KL-) was performed.
