Cancer Research Quantification of Tumor Cell Adhesion in Lymph Node Cryosections Elisa Helena Farias Jandrey1, Mayra Akemi Kuroki1, Anamaria Aranha Camargo1, Erico Tosoni Costa1 1Molecular Oncology Center, Hospital Sírio-Libanês Here, we describe a simple and inexpensive method that allows the quantification of adhesive tumor cells to lymph node (LN) cryosections. LN-adherent tumor cells are readily identified by light microscopy and confirmed by a fluorescence-based method, giving an adhesion index that reveals the tumor cell-binding affinity to LN parenchyma.
