Kaplan-Meier probability curves for central nervous system (CNS) relapse-free survival according to CNS radiation boost patient groups. There was a statistically significant improvement in 7-year CNS relapse-free survival with the addition of a CNS radiation boost to total body irradiation conditioning regimens compared with patients who did not receive a boost (100% vs 76.4%; P = .043).

3. Fig. 2
Kaplan-Meier probability curves for progression-free survival according to central nervous system radiation boost patient groups. There was no statistically significant difference in 7-year progression-free survival with the addition of central nervous system radiation boosts to total body irradiation conditioning regimens compared with patients who did not receive a boost (78.3% vs 62.5%; P = .076).

4. Fig. 3
Kaplan-Meier probability curves for overall survival according to central nervous system radiation boost patient groups. There was no statistically significant difference in 7-year overall survival with the addition of a central nervous system radiation boost to total body irradiation conditioning regimens compared with patients who did not receive a boost (49.4% vs 43.5%; P = .921).
