The median EBRT dose was 45 Gy (range 39.6 to 59.4 Gy), applied in conventional fractionation (1.8-2 Gy per fraction, 5 fractions a week).
Elective nodes received 50 Gy in 25 fractions at conventional fractionation.
The linear quadratic equation cannot reliably represent equivalent radiation effects when extrapolating from conventional fractionation (1.5 4 Gy per fraction) to high dose (12 25 Gy) single fractions for radiosurgery.
Radiation was delivered using conventional fractionation (1,8 – 2 Gy per fraction, five days per week).
Whole breast irradiation was delivered with Conventional Fractionation (CF) (50Gy, 2.0/day, 25 fractions) and moderate Hypofractionated Schedule (HS) (44Gy, 2.75Gy/day, 16 fractions) followed by tumour bed boost.
A typical conventional fractionation regimen uses 2 Gy fractions delivered daily five times a week, up to a total of 60 80 Gy, although this varies across treatment centres, tumour types and patients [3].
The conventional fractionation scheme was 2 Gy daily fractions given five times per week, for a cumulative dose of 120 Gy.
While undergoing chemotherapy, patients also received concomitant 3D CRT with conventional fractionation (1,8 - 2 Gy per fraction, five days per week).
However, dose-escalated treatment of the pelvic nodes with 56 Gy in conventional fractionation combined with hypofractionated treatment of the prostate (70 Gy in 2.5 Gy fractions) has been shown to be well tolerated [ 25].
Conventional fractionation (CF).
CF: Conventional Fractionation; HS : Hypofractionated Schedule.
