Table 3.

Dose received by 95% of target volume vs. prescription dose and local failure patterns in primary recurrences stratified by dose >60 Gy vs. <60 Gy

Dose Local failure pattern (n = 26)
Within GTV/PTV Within GTV/PTV and outward Marginal miss (within PTV and outward) Geographic miss (outside but within 1 cm of PTV)
D95 <60 Gy 6 2 0 0
Dprescr <60 Gy 6 2 0 0
D95 ≥60 Gy 6 11 1 0
Dprescr ≥60 Gy 6 11 1 0

Abbreviations: D95 = dose received by 95% of target volume; Dprescr = dose prescribed to 95% of target volume; other abbreviations as in Table 1.
