Zusammenfassung
Eine Heilung des kolorektalen Karzinoms ist nur durch eine vollständige, operative
Entfernung des Tumors möglich. Lebermetastasen können bei primärer Irresektabilität
mittels Chemotherapie verkleinert und einer kurativen Operation zugeführt werden.
Die verwendeten Chemotherapeutika schädigen hierbei auch das nicht tumorbefallene
Lebergewebe und führen zu Veränderungen, die als „Chemotherapieassoziierte Steatohepatitis”
(CASH) bezeichnet werden. Wir evaluierten ein histopathologisches Scoringsystem für
eine CASH und suchten nach präoperativen Risikofaktoren für die Entwicklung einer
CASH. Die Gabe von Chemotherapie, v. a. von Oxaliplatin, führte zum Auftreten einer
CASH. Ein höherer BMI, das männliche Geschlecht und präoperativ erhöhte Transaminasen
waren Risikofaktoren für die Entwicklung einer CASH. Postoperativ lag bei Patienten
mit einer CASH ein erhöhter Spitzen-Bilirubinwert vor. Wir fanden keine erhöhte Morbidität
oder Mortalität bei Vorliegen einer CASH.
Abstract
Colorectal cancer (CRC) can only be cured by complete resection of the tumour. Primarily
unresectable metastases of the liver are treated by chemotherapy to achieve down-sizing
of metastasis and curative resection. Chemotherapy can affect tumour-free healthy
liver tissue and lead to histopathological and functional changes summarised as ”chemotherapy-associated
steatohepatitis” (CASH). We have evaluated a histopathological scoring system for
CASH and searched for preoperative risk factors for the development of CASH. Liver
alterations such as CASH were more pronounced when patients received chemotherapy,
especially when treated with oxaliplatin. A higher BMI, male sex and elevated serum
transaminases were risk factors for the development of CASH. Patients with a higher
CASH score, reflecting more advanced changes in liver tissue, had a higher serum peak
bilirubin level postoperatively. We did not find a higher morbidity or mortality in
patients with a more severe liver damage measured by the CASH score.
