Zusammenfassung
Zielsetzung: Aufgrund des Fehlens international anerkannter Leitlinien über das Ausmaß der Lymphknotenausräumung beim Blasenkarzinom besteht bis heute Unklarheit darüber, welches Vorgehen hinsichtlich einer kurativen Zielsetzung zu favorisieren ist. Wir haben deshalb zunächst retrospektiv den Einfluss der operativen Radikalität auf die Prognose untersucht. Material und Methode: In einer retrospektiven Analyse von 506 Patienten nach radikaler Zystektomie und pelviner Lymphadenektomie wurde der Einfluss klinischer und histopathologischer Variablen auf die Prognose untersucht. Ergebnisse: In der retrospektiven Untersuchung stellten in der univariaten Analyse die pT-Kategorie (p < 0,0001), Lymphknotenstatus (p < 0,0001), Grading (p = 0,0145), Nachweis einer Harnstauungsniere (p = 0,0007), Anzahl der durchgeführten transurethralen Resektionen (p = 0,0043), Operateur (p = 0,0033) und Anzahl der entfernten Lymphknoten (p = 0,0012) statistisch signifikante Einflussgrößen dar. Bei einem Mittelwert von 14,3 entfernten Lymphknoten (Spannbreite 1 - 46) unterschieden sich Radikalität (p < 0,001) und Prognose (p = 0,0049) signifikant zwischen den Operateuren. In der multivariaten Analyse waren pT-Kategorie (p = 0,003), pN-Kategorie (p < 0,001) und Anzahl der entfernten Lymphknoten (p = 0,038) unabhängige Einflussfaktoren. Schlussfolgerung: Eine ausgedehnte Lymphadenektomie verbesserte in unserem retrospektiv untersuchten Kollektiv signifikant die Prognose und stellte damit eine potenziell kurative Maßnahme dar. Auf dem Boden dieser Ergebnisse müssen prospektive Untersuchungen klären, wo der Standard für die pelvine Lymphadenektomie liegt und welchen Überlebensvorteil die radikale Chirurgie für den Patienten bietet.
Abstract
Purpose: Due to the absence of internationally recognised guidelines on the necessary extent of lymphatic node removal in carcinoma of the bladder, we are still not sure as to which procedure is most favourable to therapeutic success. Hence, we checked retrospectively on the influence exercised by radical surgery on prognosis. Material and Method: 506 patients were analysed retrospectively after radical cystectomy and pelvic lymphadenectomy with regard to the influence exercised on prognosis by clinical and histopathological variables. Results: Statistically significant influential factors in univariate analysis were in the retrospective examination: the pT category (p < 0.0001), lymphatic node status (p < 0.0001), grading (p = 0.0145), proof of uronephrosis (p = 0.0007), number of performed transurethral resections (p = 0.0043), surgeon (p = 0.0033) and number of resected lymph nodes (p = 0.0012). There was a significant difference between surgeons at a median number of 14.3 removed lymphatic nodes (range 1 - 46) in respect of radicality (p = 0.001) and prognosis (p < 0.0049). Independent influential factors in multivariate analysis were: pT category (p = 0.003), pN category (p < 0.001) and the number of surgically removed lymphatic nodes (p = 0.038). Conclusion: In our retrospectively examined group of patients extensive lymphadenectomy significantly improved the prognosis and was thus a potentially curative procedure. Basing on these results, prospective studies will have to clarify the level of the standard applicable to pelvic lymphadenectomy and also the advantages and prospects of radical surgery in respect of possible patient survival.
