Table 2 Incidence of pulmonary toxicity related to time after total body irradiation according to the groups classified by the dose rate
Reduced group, dose rate < 6 cGy/min (N = 23) | Conventional group, dose rate ≥ 6 cGy/min (N = 54) | P-value | |
|---|---|---|---|
Follow-up time (month) | 10.6 (0.7–30.6) | 12.6 (0.5–191.9) | 0.114b |
Overall Pulmonary toxicity | 10 (43.5%) | 40 (74.1%) | 0.010a |
Infectious PT | 8 (34.8%) | 28 (51.9%) | |
Non-infectious PT | 2 (8.7%) | 12 (21.8%) | |
3 month - Pulmonary toxicity | 5 (21.7%) | 20 (37.1%) | 0.085b |
6 month - Pulmonary toxicity | 9 (39.7%) | 28 (52.3%) | 0.085b |
Time to PT after TBI (month) | 3.7 ± 3.4 (0.5–11.8) | 5.2 ± 6.5 (0.1–30.9) | 0.085b |
