PURPOSE

To evaluate the relationship between health related quality of life (HRQoL) regarding urinary morbidity and postimplant dosimetry after permanent prostate brachytherapy.

METHOD AND MATERIALS

The EORTC QLQ-PR25 and the modified ICS-male questionnaire were sent to 296 men treated with prostate brachytherapy at Mannheim Medical Centre, University of Heidelberg/Germany between June 1998 and 2003 December. 258 patients were alive at time of assessment. Of 238 questionnaires (92% response rate) 231 were suitable for analysis (97%). Median follow up was 51 months (13-78 months). Postimplant dosimetry was based on CT-images taken 6 weeks after implantation of the iodine-125 seeds. Calculated parameters were prostate volume receiving 100% (V100), 150% (V150) and 200% (V200) dose, dose to 90% of the prostate volume (D90).

RESULTS

Patients with urge symptoms had higher values for D90, V100, V150 und V200 as patients without urge symptoms. Patients with urinary incontinence and stress incontinence have larger prostate volumes.

CONCLUSION

Prostate volume and D90 are relevant parameters for HRQoL regarding urinary morbidity.
