Sampling by cryo-biopsy (fig. 7).
Lymph node station 7 sampled.
Histology and Immunohistochemistry
Sample from LN 7 proves positive for lung cancer (despite the small size of the lymph node). Tissue samples from tumour prove positive for BerEP4 and CK7, less for AE1/3 and weak for KL-1, in addition weak for NSE and Synaptophysin.
Strongly positive nuclei for TTF-1 in absence of an immune reaction to CD45, GFAP, CK5/6 or p63. Proliferation rate regional variable between 70-80% (Ki67).
