PurposeTo describe prospectively the long-term health-related quality of life (HRQOL) and treatment-related symptoms in patients with localized prostate cancer treated with neoadjuvant androgen deprivation therapy and radical radiotherapy (RT), including external beam RT and iridium high-dose-rate brachytherapy, and to compare them with age-matched normative data.Methods And MaterialsA total of 93 patients with T1-T3a tumors consecutively treated with definitive RT at our institution completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30 and QLQ-prostate specific 25-item (PR25) module twice at an 18-month interval 0-18 months after RT. Subgroups were analyzed regarding acute and late effects on symptoms and quality of life.ResultsThe main analysis included 80 patients who were disease free at the final assessment. The levels of HRQOL were generally high, did not change over time, and were comparable to the normative data. Symptom development (urinary, bowel, and sexual) correlated well with the known acute and late effects of radical RT and neoadjuvant androgen deprivation therapy.ConclusionCombining external beam RT and HDR brachytherapy when treating prostate cancer did not appear to impair HRQOL and was comparable to that of other brachytherapy methods. The negative contribution from late neoadjuvant androgen deprivation therapy on symptom development seemed to be substantial but mostly transitory. Additional research is needed to determine the long-term HRQOL (3-5 years), and interventional randomized studies are suggested.
