Mn. Gaze et al., PAIN RELIEF AND QUALITY-OF-LIFE FOLLOWING RADIOTHERAPY FOR BONE METASTASES - A RANDOMIZED TRIAL OF 2 FRACTIONATION SCHEDULES, Radiotherapy and oncology, 45(2), 1997, pp. 109-116
Background: The optimum dose and fractionation schedule for the pallia
tive irradiation of painful bone metastases is controversial. Purpose:
To compare the efficacy, side-effects and effect on quality of life o
f two commonly used radiotherapy schedules in the management of painfu
l bone metastases. Materials and methods: In a prospective trial, 280
patients were randomised to receive either a single 10 Gy treatment or
a course of 22.5 Gy in five daily fractions for the relief of localis
ed metastatic bone pain. Results: Response rates have been calculated
from 240 assessable treated sites of pain. The overall response rates
were 83.7% (single treatment) and 89.2% (five fractions). The complete
response rates were 38.8% (single treatment) and 42.3% (five fraction
s). The median duration of pain control was 13.5 weeks (single treatme
nt) and 14.0 weeks (five fractions). None of these differences was sta
tistically significant. There were no differences between the groups i
n the effect of treatment on a variety of quality of life parameters.
Conclusions: It is concluded that a single 10 Gy treatment is as effec
tive as a course of 22.5 Gy in five fractions in the management of pai
nful bone metastases. (C) 1997 Elsevier Science Ireland Ltd.
