I am working with TCGA clinical data file for some analyses. I need Her2 status in breast cancer patients. There are some variables that identify her2 status as positive or negative according IHC and ISH methods. I need to clarify these situations according all existing data.I want to know what are these Variables?
"patient.her2_neu_breast_carcinoma_copy_analysis_input_total_number" "patient.her2_neu_and_centromere_17_copy_number_metastatic_breast_carcinoma_analysis_input_total_number_count" and "patient.her2_neu_and_centromere_17_copy_number_analysis_input_total_number_count"
and also I want to know "patient.lab_procedure_her2_neu_in_situ_hybrid_outcome_type" variable has been identified based an which variable? just patient.her2_neu_chromosone_17_signal_ratio_value? or with another such as copy number of her2? I would be grateful if you could kindly help me.
