Image-guided hypofractionated radiotherapy and quality of life in localized prostate cancer: Prospective longitudinal study on 337 patients - Abstract

PURPOSE: To prospectively analyse quality of life (QoL) in a cohort of prostate cancer patients undergoing treatment with a course of hypofractionated image-guided radiotherapy (hypo-IGRT).

MATERIAL AND METHODS: Between 8/2006 and 1/2011, 337 cT1-T2N0M0 prostate cancer patients (median age 73 years) were eligible for this prospective longitudinal study on hypo-IGRT (70.2Gy/26 fractions), employing one out of 3 IGRT modalities (transabdominal ultrasound, X-Ray, cone-beam computed tomography) available at our Radiation Oncology Department. Patients filled in 4 questionnaires before treatment, and at 6, 12 and 24 months afterwards: the International Index of Erectile Function-5 (IIEF-5), the International Prostate Symptom Score (IPSS), the European Organization for Research and Treatment of Cancer (EORTC) prostate-cancer-specific QLQ-PR25 and QLQ-C30.

RESULTS: Patients follow-up was updated to at least last questionnaire time point (median follow-up 19 months). Significant deterioration in erectile function (IIEF-5) was registered over time only in the patients without androgen deprivation (p=0.0002). No change over time was observed in urinary symptoms-related QoL at the QLQ-PR25 and IPSS questionnaires. Slight deterioration in the QLQ-PR25 bowel symptoms-related QoL was observed (p=0.02). Overall, the QLQ-C30 Global Health Status was found to be improved over time (p=0.03) and significantly correlated at univariate analysis to the maximum RTOG/EORTC urinary and bowel late toxicity score after radiotherapy.

CONCLUSIONS: The regimen of hypo-IGRT with multiple imaging modalities adopted in our Radiation Oncology Department for localised prostate cancer might be a successful strategy for dose escalation with limited impact on different aspects of QoL over time.
