Zusammenfassung

Kolorektale Karzinome waren 1992 in Deutschland mit 25,5 Toten auf 100 000 Einwohner die zweithäufigste Krebstodesursache (Statistisches Jahrbuch 1993). Die höchsten Inzidenzen finden sich in den sozioökonomisch höchstentwickelten Ländern mit Ausnahme Japans (z. B. 35,8 auf l00 000 in Connecticut/USA), die niedrigsten in den Entwicklungsländern (z. B. 1,9 auf l00 000 im Senegal). In den USA ist von 1950 bis 1980 die Häufigkeit des Kolonkarzinoms um 30% angestiegen, die des Rektumkarzinoms dagegen gleichgeblieben. Bei Männern zeigte sich insgesamt ein stärkerer Anstieg.
