PEARSON CORRELATION

D_{90} (α/β = 2)


Interventions (n)

p = 0.004

Cumulative Pseudolesion (cm^{3})

p = 0.037

Interval: first irradiation  MRT (months)

p = 0.005

Interval: last irradiation  MRT (months)

p = 0.745

Mean interval between several interventions (ΣT/n)

p = 0.092

 The D90 (for α/β = 2) correlated significantly positive with the number of interventions and the interval between the first irradiation and the last MRI (p < 0.05). There was a significant negative correlation between the D90 (for α/β = 2) and the volume of the cumulative pseudolesion (p = 0,037). There was a trend for a positive correlation (p = 0.092) between the D90 (for α/β = 2) and the mean interval between several interventions (ΣT/n).
