Lancet Oncol 2014 Chirurgische behandeling maagcarcinoom 15 jaar follow-up resultaten D1-D2 studie • Uitgebreide D2 lymfklier dissectie leidt tot minder loco-regionale recidieven en lagere ziekte-specifieke sterfte dan een beperkte D1 dissectie • D2 dissectie is geassocieerd met hogere post-operatieve morbiditeit, mortaliteit, en aantal re-interventies • D2 dissectie (>15 ln) is de aanbevolen chirurgische benadering (zonder milt- en pancreasstaart resectie, in specialiseerde hoog-volume centra) • Na curatieve resectie blijft de incidentie van loco-regionale recidieven hoog Songun et al.

ESMO-ESSO-ESTRO Guidelines, Ann Oncol 2013 Samenvatting • Maagcarcinoom heeft een slechte prognose • Ondanks adequate chirurgie zijn LR recidieven frequent • Peri-operatieve chemotherapie en post-operatieve chemoradiotherapie verbeteren de overleving • R1 resecties is prognostisch (zeer) ongunstige factor • Post-operatieve chemoradiotherapie verbetert mogelijk prognose na R1 resectie • Pre-operatieve chemoradiotherapie lijkt veelbelovend Met dank aan Edwin Jansen Anouk Trip Jurriën Stiekema Steven Vanhoutvin Johan Dikken Johanna van Sandick Elma Meershoek-Klein Kranenbarg Henk Boot Nicole van Grieken Cornelis van de Velde Annemieke Cats Marianne Nordsmark Pehr Lind
