A: Patient 658: adenocarcinoma of the lung, pleural effusion. Highly hyperdiploid cell showing seven hybridization signals for chromosome 3 (green fluorescence) and eight copies for chromosome 17 (red fluorescence). Note intratumor heterogeneity in comparison with surrounding cells. B: Patient 744: normal cells from bronchial epithelium with disomic results for chromosomes 17 (red fluorescence) and 18 (green fluorescence). Imprint of bronchoscopically gained biopsy specimen shows conserved architecture. C: Patient 744: another group of disomic cells (chromosomes 18, green fluorescence, and 17, red fluorescence). D: Patient 744: nest of four tumor cells (adenocarcinoma). Green hybridization signals represent copies of chromosomes 11, red signals represent copies of chromosome 7. Again, a marked heterogeneity of aneuploid cells is observed. Note that the yellow signal results from overlapping green and red signals. E: Patient 701: brushing: inconspicuous cell from a patient with squamous cell carcinoma: interphase FISH reveals two signals for chromosome 17 (red fluorescence) and four signals for chromosome 18 (green fluorescence). F: green signals representing chromosome 18 in the same nucleus are shown in more detail using a different filter set. C: Patient 172: double color FISH in a highly aberrant tumor cell (squamous cell carcinoma) showing more than 10 signals for chromosome 3 (green signals) and 17 (red signals). Note that not all signals are in the same plane of the focus due to the three-dimensional structure of the nucleus.
