Table 2.

Hippocampal dosimetric parameters of three cohorts.

	HA-PCI (n = 16)	NPC-GBM (n = 11)	SVZ-GBM (n = 3)
D100% (Gy)
Mean	4.2	12.0	44.7
Range	3.4–4.8	1.0–13.6	43.5–45.8
D_max (Gy)
Mean	7.6	42.8	61.7
Range	5.5–9.4	36.8–64.7	60.9–62.2
D50% (Gy)
Mean	5.1	23.6	54.5
Range	3.9–5.6	2.1–61.1	50.7–60.5
D_1cc (Gy)
Mean	5.5	37.5	58.0
Range	4.1–6.2	14.7–63.5	56.3–61.0
D_0.5cc (Gy)
Mean	5.8	40.9	60.3
Range	4.4–6.7	23.2–64.1	59.3–61.6

All doses were expressed in EQD2: biologically equivalent doses in 2-Gy fractions assuming an α/β ratio of 2 Gy. Both hippocampi were included in the analysis.
