Strahlentherapie beim Prostatakarzinom

Radiotherapy in prostate cancer

Zusammenfassung

Bislang sind radikale Prostatektomie und Strahlentherapie gleichwertige Verfahren hinsichtlich ihrer onkologischen Wirksamkeit, sofern die Strahlentherapie adäquat dosiert erfolgt. Es stehen die interstitielle Brachytherapie, die perkutane Radiotherapie oder Kombinationen zur Verfügung. Für die Weiterentwicklung strahlentherapeutischer Verfahren ergibt sich insbesondere für Patienten mit intermediärem Risiko ein technologisches Optimierungsfenster über die Dosiseskalation. Neuere Entwicklungen wie die intensitätsmodulierte und bildgeführte Strahlentherapie erlauben eine Applikation höherer Dosen ohne eine relevante Steigerung der Nebenwirkungsraten. Darüber hinaus scheint für definierte Patientenkollektive eine additive Hormontherapie verbesserte Kontrollraten zu erreichen. Nach R1-Resektion verbessert eine adjuvante Bestrahlung das rezidivfreie Überleben; bei später auftretenden lokoregionären Rezidiven ist eine Radiatio die bislang einzige kurative Option.

Abstract

Radiotherapy is a well-accepted treatment modality for patients with localised prostate cancer. Provided that radiotherapy is applied with a sufficient radiation dose, it is as effective as radical prostatectomy. Different radiation modalities are available (interstitial brachytherapy, external beam radiotherapy or a combination of both). Various new developments will further increase the value of radiation-based approaches. In this regard, a wider use of intensity-modulated radiotherapy (IMRT) and image-guided radiotherapy (IGRT) will result in higher treatment doses with even lower toxicity rates. Combinations of radiotherapy and hormonal ablation improve local control rates in defined groups of patients. After prostatectomy with positive surgical margins, adjuvant radiotherapy improves disease-free survival rates; in cases of local relapse, salvage radiotherapy is the only potentially curative treatment approach.
