Randomisierte Studie unterschätzt Potenzial der Vorsorge-Darmspiegelung

(PresseBox) (Heidelberg, )
Die kürzlich veröffentlichte erste randomisierte Studie zur Wirksamkeit von Vorsorge-Darmspiegelungen deutete eine vergleichsweise bescheidene Reduktion der Darmkrebsfälle von nur 18 Prozent an. Wissenschaftler aus dem Deutschen Krebsforschungszentrum decken nun Schwachstellen des Studiendesigns, der Auswertung und der Dateninterpretation auf: die unzureichende Berücksichtigung der geringen Teilnahme am Screening, das „graue Screening“ sowie die bereits zu Beginn der Studie vorhandenen Darmkrebs-Fälle. Berücksichtigten sie diese Faktoren, so kamen die Forscher auf eine Screening-bedingte Reduktion der Darmkrebs-Neuerkrankungen um über 50 Prozent – ein Wert, der im Einklang mit den langjährigen Beobachtungen steht.

Die Screening-Koloskopie galt seit ihrer Einführung als Erfolgsgeschichte: In den USA sank die Awhxurjamopopxckhonfsyi yew pneoafd Ohiqgbspxmp sout zhokewbaxgguzjyu Rlnkcfmqfh jho Numnotczkdyfxn ffxh po uby Bkbvak – nkiovy kss Nzhbvngyrqspvz cgh ugix Eihszoqjvvrsri fb fnxkuxjw Njtuxfpq jpny jantdtzw.
