Zusammenfassung
Die primäre Radiochemotherapie ist vor allem bei Patienten zu erwägen, deren Organfunktion postoperativ nicht erhalten werden kann oder bei nichtresektablen Tumoren. Die intensitätsmodulierte Radiotherapie (IMRT) scheint zu einer geringeren Spättoxizität und damit zu einer Verbesserung der Lebensqualität zu führen. Ob die IMRT im Vergleich zu einer konventionellen Radiotherapie zu einer Verbesserung der lokalen Kontrolle führt, bleibt weiterhin offen. Die Langzeittoxizitäten der jeweiligen Therapie sind mit dem Patienten abzuwägen, um eine optimale Therapie mit minimalen Risiken zu erreichen. Neuere Ansätze mit einer Kombination aus Bestrahlung und biologischen Targettherapeutika sind ebenfalls eine Option. Diese Substanzen werden vermehrt in Therapieprotokolle integriert. Die prätherapeutischen Selektionskriterien für ein gutes Ansprechen auf eine sog. Targettherapie fehlen bislang.
Abstract
Primary radiochemotherapy is a treatment option for patients with locally advanced or unresectable head and neck cancer. Compared to conventional radiotherapy, intensity-modulated radiotherapy (IMRT) is associated with fewer long-term toxicities and better quality of life. Whether IMRT improves local control in these patients needs to be further investigated. The risk factors and treatment toxicities must be taken into consideration and discussed with the patients. New approaches combining radiotherapy and biological targets are a treatment option. The implementation of these substances in treatment protocols is increasing. Sensitive and specific prognostic biomarkers for patient identification to optimize treatment selection are important, but reliable parameters are still missing.
