The prevalence of long term survivors after cancer treatment is increasing and a large number of patients are at risk for development of treatment-related sequelae. With limitation of health care resources, low cost methods are needed to screen this population for sequelae.
A total of 255 prostate cancer patients treated with curative radiotherapy at one institution was identified and responses to self-reported questionnaires based on Soma score for rectal and urinary symptoms were analyzed and compared with a similar questionnaires filled in by an experienced study nurse during patient interview.
Results: 65% of living patients returned the questionnaires and 51% showed up for the interview. The median follow up time after irradiation was 6,9 years. 57% of the patients scored the same as the nurse in an interview setting, while 35% scored higher in the self reported forms than in the interview scores. Overall, the self-reported questionnaire identified 97% of patients with scores >2 at interview.
Conclusion: Self reported questionnaires may be a low cost method to help screen populations at risk for treatment related sequelae after prostate irradiation.
