Abstract

Purpose:

Aim of this analysis was to assess the current status of prostate cancer radiotherapy in Austria and compare these numbers to patients treated with surgery.

Material and Methods:

A questionnaire was sent to all 14 Austrian departments asking about numbers of prostate cancer patients treated and indication of treatment (primary, postoperative), as well as the treatment technique used (3D-CRT, IMRT, brachytherapy), treatment volumes (with/without pelvic irradiation), dose applied, and differences in treatment concepts. Data investigated were based on the year 2007.

Results:

Of the 14 departments (65%), 9 departments decided to participate. A total of 1,191 prostate cancer patients were treated (847 primary, 344 postoperative). Primary patients were treated by external beam technique (91%) and permanent interstitial brachytherapy (9%). All postoperative patients were treated by 3D-CRT. Dose ranged from 70–78 Gy for primary pa-tients and from 60–72 Gy for postoperative patients. A risk-adapted dose prescription was performed in 5 centers. Additional pelvic lymph node irradiation was based on signs of positive nodes in 4 departments and based on Roach formula/Partin table in 5 departments.

Conclusion:

About 25% of prostate cancer patients receive primary radiotherapy. This number reflects a high potential to conduct national studies. Treatment technique and dose applied was in all centers investigated in accordance with the German S3 guidelines.

Zusammenfassung

Ziel:

Erfassung des aktuellen Status zur Strahlentherapie des Prostatakarzinoms in Österreich und Vergleich mit den Zahlen operierter Patienten.

Material und Methodik:

Alle 14 radioonkologischen Zentren erhielten, basierend auf dem Jahr 2007, einen Fragebogen zur Anzahl der behandelten Patienten, Behandlungsintention (primär/postoperativ), Behandlungstechnik (3D-CRT, IMRT, Brachy-therapie), zu Zielvolumina (mit/ohne Beckenbestrahlung), Dosis und unterschiedliche Therapiekonzepte.

Ergebnisse:

9 von 14 Zentren (65%) nahmen an der Befragung teil – Abbildung 1. Insgesamt wurden 1191 Prostatakarzinom-patienten behandelt (847 primär – 344 postoperativ). Primäre Patienten wurden zu 91% mittels Teletherapie – Dosis 70–78 Gy – und 9% mittels Brachytherapie behandelt – Tabelle 1. Alle postoperativen Patienten erhielten eine Teletherapie – Dosis 60–72 Gy. Eine risikoadaptierte Dosisanpassung erfolgte in 5 Zentren. Die Beckenlymphknoten wurden in 4 Zentren bei positivem Befund und in 5 Zentren entsprechend der Roach-Formel bzw. der Partin-Tabelle mitbestrahlt.

Schlussfolgerung:

Etwa 25% aller Prostatakarzinompatienten erhielten eine primäre Radiotherapie. Diese Anzahl zeigt ein hohes Potential an Patienten für allfällige Studien. Die erfassten Daten waren in Übereinstimmung mit den deutschen S3-Leitlinien.
