Table 2.

Survival time of 25 responders

	Median, days
One-time irradiation response group (n = 19/25; responder)*	76 (46–240)
Re-irradiation group (n = 6/25; responder)**	112 (87–299)
Overall survival (n = 25)	91 (46–299)
Disease-free survival (n = 25)	63 (33–196)
*Time to death from the end of initial irradiation
**Time to death from the end of re-irradiation

There is a significant difference in survival time between the one-time irradiation group and the re-irradiation group; log-rank test (p = 0.02).
