BACKGROUND, The objective of this study was to describe prospectively duali
ty of life (QOL) before and after radiotherapy for patients with prostate c
arcinoma.
METHODS. Forty-three patients with T1-T3 prostate carcinoma who underwent c
onformal external beam radiation therapy were randomized either to the comp
lete European Organization for Research and Treatment of Cancer (EORTC) QOL
questionnaire (EORTC QLQ-C30) or the Medical Outcomes Study Group Short Fo
rm Wealth Survey (SF-36) at baseline, at 3 weeks and 6 weeks after initial
treatment, and at 6 weeks and 5 months after the completion BE radiotherapy
. The measures were self-reported patient QOL, and values are given as the
mean +/- standard error of the mean. Changes in QOL are described from base
line to the end of treatment in both questionnaire groups.
RESULTS. Emotional role functioning, as measured with the SF-36 questionnai
re, significantly improved from 68.2 +/- 9.9 at baseline to 93.3 +/- 5.2 at
the end of therapy (P = 0.02). The EORTC QLQ-C30 questionnaire revealed co
nsistent values of emotional functioning during treatment (72.7 +/- 5.9 at
baseline) but showed a significant improvement 6 weeks after therapy (89.0
+/- 4.4; P = 0.01). Role functioning deteriorated from 80.1 +/-: 6.5 at bas
eline to 62.5 +/- 8.8 at the end of radiotherapy (P = 0.02). Symptoms of fa
tigue were shown to increase significantly from 26.9 +/- 6.0 at baseline to
37.7 +/- 7.6 at the end of therapy (P = 0.02). No significant changes in t
he other dimensions were observed in either questionnaire.
CONCLUSIONS, After radiotherapy for prostate carcinoma, patients experience
a temporary deterioration of fatigue and role functioning as measured with
the EORTC QLQ-C-30. Despite physical deterioration, the authors observed a
n improvement in emotional functioning scores with both questionnaires. Thi
s may have been due to psychological adaptation and coping. (C) 2000 Americ
