Zusammenfassung
Zur Abklärung eines Verdachts auf das Vorliegen eines kolorektalen Karzinoms ist die Durchführung einer kompletten Koloskopie obligat. Nach Karzinomdiagnose sollten im Rahmen des präoperativen Stagings routinemäßig eine Abdomen-Sonographie, ein Röntgen-Thorax sowie eine CEA-Bestimmung erfolgen. Der Familienanamnese kommt eine wichtige Bedeutung zu, um hereditäre Darmkrebsformen zu identifizieren. Beim Rektumkarzinom ist eine weitere lokale Bildgebung zur operativen Planung und Beurteilung der Notwendigkeit einer neoadjuvanten Therapie wünschenswert. Beim Kolonkarzinom ist eine weitere bildgebende Diagnostik nur bei speziellen Fragestellungen wie dem Verdacht auf das Vorliegen von Metastasen erforderlich.
Abstract
Whenever a colorectal cancer is suspected a complete colonoscopy is required as the appropriate work up. Once the colorectal cancer diagnosis has been established the preoperative staging should include an abdominal ultrasound, a chest X-ray and a serum-CEA measurement. In order to identify hereditary colorectal cancer forms a thorough family history is mandatory. For the work up of a rectal cancer further local imaging is helpful for the surgical planning and to determine whether neoadjuvant therapy is warranted. The work up of a colon cancer only requires additional radiological imaging in special situations, e. g. if metastases are suspected.
