Comparison of CTCs karyotyping before and after treatment. a. The ratio of triploid, tetraploid, and multiploid CTCs in 12 NPC patients decreased after chemotherapy, while diploid CTCs was remained the same. b. For PR patients, the ratio of tetraploid CTCs definitely decreased from 66.7 to 33.3%, while triploid CTCs decreased from 88.9 to 66.7%, and multiploid CTCs decreased from 44.4 to 33.3% after treatment. c. For PD/SD patients, the frequency of tetraploid CTCs decreased from 66.7 to 33.3%, while triploid CTCs increased from 66.7 to 100%, and multiploid CTCs remained unchanged (33.3% versus 33.3%) after treatment
