Zusammenfassung

GRUNDLAGEN: Das kolorektale Karzinom (KRK) ist die zweithäufigste krebsbedingte Todesursache in der westlichen Welt. Das Ziel der palliativen Therapie ist die Überlebensverlängerung und Verbesserung der Lebensqualität. METHODIK: Die Beschreibung der Therapieoptionen basiert auf einer systematischen Literatursuche und auf den Empfehlungen der aktuellen S3 Leitlinie zur Behandlung des metastasierten KRK. ERGEBNISSE: Ein Darmverschluss durch gastrointestinale Tumorobstruktion kann in der palliativen Situation durch die endoskopische Einlage von selbstexpandierenden Metallstents behandelt werden. Die systemische palliative Behandlung ist durch die Einführung neuer, effektiver Chemotherapeutika entscheidend verbessert worden. SCHLUSSFOLGERUNGEN: Bei tumorbedingten Symptomen oder Progress der Erkrankung ist eine intensive Kombinationschemotherapie indiziert. Durch den Einsatz von zielgerichteten Substanzen wird eine Verbesserung des Überlebens erreicht. Vor Kurzem wurde mit dem Mutationsstatus des KRAS-Onkogens ein erster prädiktiver molekularer Marker in die klinische Praxis eingeführt, was einen entscheidenden ersten Schritt hin zu einer Individualisierung der Therapie darstellt.

Summary

BACKGROUND: Colorectal cancer (CRC) is the second leading cause of cancer death in the western world. The aim of palliative therapy is the prolongation of survival and the improvement of quality of life. METHODS: The description of therapeutic options is based on systematically literature search and on the German S3 guideline for metastatic CRC treatment. RESULTS: In the case of gastrointestinal tumour obstruction, endoscopic self-expanding metal stents (SEMS) insertion is a non-surgery palliative treatment option. New and effective chemotherapeutic substances and biologics have improved the systemic treatment of patients with mCRC in the past decade. CONCLUSIONS: Endoscopic or intensive combination chemotherapy is indicated if the patient suffers from tumour symptoms or disease progression. Combination therapy with monoclonal antibodies leads to further improvement of survival. The introduction of the mutational status examination of the KRAS oncogene as the first predictive marker into clinical care is an important step towards the individualization of treatment.
