Cumulative incidence of t-ML.

The incidence of t-ML differed among the 14 patients who received radiation therapy (RT) and G-CSF, the 44 patients who received RT and no G-CSF, the 85 patients who received G-CSF but no RT, and the 269 patients who received neither G-CSF nor RT (P = .017). For those who did not receive RT (bottom left), there was a higher incidence (P = .0192) of t-ML top among those who did versus did not receive G-CSF (6-year estimates, 11.0% ± 3.5% versus 2.7% ± 1.3%). For those who did not receive G-CSF (bottom right), there was a higher incidence (P = .0038) of t-ML among those who received RT (6-year estimate, 12.3% ± 5.3%) than among those who did not receive RT (6-year estimate, 2.7% ± 1.3%).
