This example shows findings from a cytogenetic assessment of EGFR gene copy number amplification with the purpose of determining the diagnostic status of patients with non-small cell lung cancer. In this example, the findings are generated using fluorescence in situ hybridization (FISH) methodology and semi-quantitative microscopic assessment by a pathologist. Microscopic assessments are then summarized to a diagnostic status using a specific algorithm represented in GFANMTH.
Row 1:
Shows the total number of centromere probe signals in the nuclei of the counted cells associated with the location represented in variable GFGENLOC for chromosome 7.
Row 2:
Shows the total number of EGFR probe signals in the nuclei of the counted cells.
Row 3:
Shows the calculated ratio of the EGFR probe signals to centromere probe signals.
Row 4:
Shows the EGFR amplification status of the sample according to the 2009 Colorado Scoring Method for EGFR Gene Amplification Algorithm.
