Abstract
A rising CEA level did not indicate an early tumour recurrence in the follow-up of 660 patients with curative surgery because of colorectal carcinoma. In case of rectal carcinoma the first rise of the tumour marker preceded diagnosis of recurrence by other means 7.9 months on an average, in case of colonic carcinoma 5.1 months. The long-term survival after secondary procedure was 17.5% for patients with normal CEA value at time of reoperation and surmounted life expectancy of patients with rising tumour-marker level significantly (5.9%). The worst prognosis was found for the collective with rising CEA before diagnosis of relapse by other means, none of whom was saved by reoperation. The resectability rate of metastases was higher than that of local recurrences with nearly identical survival for both groups. Because of the long CEA lead times advances in therapy by second-look procedures are to be expected mainly for patients with pelvic recurrences after abdominoperineal extirpation. In der Nachsorge von 660 kurativ operierten Patienten mit colorectalem Carcinom erwies sich ein Anstieg des CEA nicht als Indikator eines frühen Tumorrezidives. Beim Rectumcarcinom ging ein positiver CEA-Test der Diagnose durch andere Verfahren durchschnittlich um 7,9 Monate, beim Coloncarcinom um 5,1 Monate voraus. Das Langzeitüberleben nach Rezidivoperation betrug für Patienten mit normalem CEA-Test zum Zeitpunkt der Zweitoperation 17,5% und übertraf die Lebenserwartung für Patienten mit ansteigendem Tumormarkerspiegel signifikant (5,9%). Die schlechteste Prognose ist dem Kollektiv mit ansteigendem CEA vor Rezidivdiagnose durch andere Verfahren zuzuschreiben, von denen keiner geheilt wurde. Die Resektabilitätsquote von Organmetastasen übertraf die der locoregionären Rezidive, das Langzeitüberleben von beiden Gruppen erwies sich als nahezu identisch. Fortschritte in der Therapie lassen sich durch Second-look-Operationen wegen der langen Vorwarnzeit vorwiegend bei präsacralen Tumorrezidiven erhoffen.This publication has 23 references indexed in Scilit:
