Zusammenfassung

Komorbidität ist das gleichzeitige Vorliegen einer oder mehrerer weiterer Diagnosen neben der behandelten Erkrankung. Die mittlere Zahl der Begleiterkrankungen nimmt mit dem Alter zu. Bei Kandidaten für eine radikale Prostatektomie sind 2 Aspekte der Komorbidität von Interesse: ihre Assoziation mit perioperativen Komplikationen und mit dem langfristigen Überleben. Zur Vorhersage der Langzeitprognose ist der Charlson-Score die am umfangreichsten untersuchte Komorbiditätsklassifikation. Dieser Score wurde beim Prostatakarzinom als unabhängiger Prognosefaktor identifiziert. Auch Daten der präoperativen kardiopulmonalen Risikoabschätzung können zur Identifikation von Patienten mit einem erhöhten Mortalitätsrisiko genutzt werden. Die Aussagekraft der Komorbidität erscheint hinsichtlich der Vorhersage der Gesamtmortalität in etwa der des Gleason-Scores, dem wichtigsten überlebensrelevanten tumorassoziierten Faktor, vergleichbar. Die Identifikation prognoserelevanter Einzelerkrankungen und die Entwicklung einer „für die radikale Prostatektomie spezifischen“ Komorbiditätsklassifikation könnte in Zukunft die Stratifizierung der Patienten verbessern, die für diesen Eingriff in Frage kommen.

Abstract

The coexistence of another diagnosis beside the index disease under study is defined as comorbidity. Comorbidity increases with advancing age. In candidates for radical prostatectomy, two aspects of comorbidity are of interest: its association with perioperative complications and long-term survival. The Charlson score is the most extensively studied comorbidity classification for the prediction of long-term outcome. Several studies have identified this score as an independent prognostic factor in the prostate cancer setting. In addition to the Charlson score, data collected during the preoperative cardiopulmonary risk assessment may deliver information identifying patients with an increased long-term mortality risk. The meaningfulness of comorbidity in predicting overall mortality seems to be comparable to that of the Gleason score, the most important tumor-related predictor of survival in prostate cancer. The identification of prognostically relevant single conditions and the development of a “radical prostatectomy-specific” comorbidity classification might improve the stratification of candidates for radical prostatectomy in the future.
