Prostaatkanker
• Meest voorkomende maligniteit bij
mannen
• US : incidentie 240.890 in 2011
• In NL vanaf 1990 verdubbeling
– Toegenomen PSA screening
– Populatie vergrijzing
• Sterfte na 1995 met 30% omlaag!
Detectie
• PSA
• Digital rectal exam (DRE)
• TRUS biopsy  Gleason score
• Risico bepaling met nomogrammen
(Partin)
Behandeling
• “watchfull waiting” (laag risico)
• Radicale prostatectomie (hoger risico)
• Radiotherapie (hoger risico)
• Hormoon therapie (bij uitzaaiingen)
• Bij hoger risico aanvullend onderzoek
Stadiëren (TNM)
• T = Locale doorbraak  (f)MRI
• M = Metastasen op afstand  Botscan
• N = Nodes = Lymfklieren
– CT of MRI
– Vorm en grootte (Jager et al.)
– Sensitiviteit < 50%!
• Pelvic Lymph Node Dissection (PLND)
Ferumoxtran-10
• USPIO (Sinerem®)
• Ultrasmall Superparamagnetic Iron
Oxide Particle
Ferumoxtran-10
Studie
• Kosten-effectiviteit van MRL
• Kan MRL een PLND vervangen bij een
negatieve uitslag?
• Kosten t.o.v. PLND + CT?
• 375 patiënten met bewezen Pca
• PSA > 10 of Gleason > 6 of T3 Tumor
• 4 universitaire en 7 perifere centra
Paradigma Shift
41 % buiten operatie gebied
• 49% obturator
• 20% internal / presacral
• 6% para aortal
• 4% external (lateraal)
MD CT Ferumoxtran MRI
Radioloog vs Uroloog
Conclusie
• MRL is sensitiever vergeleken met MD-
CT (34% vs 82/93%)
• Hoge NPV en de post test probability is
laag genoeg om PLND achterwege te
laten(< 2%)
• Lagere kosten (€1600) en geen post-
operatieve morbiditeit
Medische paradox
• …Ondanks 400 positieve peer reviewed
artikelen wordt ferumoxtran-10 niet
meer gemaakt…
