Zusammenfassung
Die neoadjuvante/perioperative Therapie mit radikaler Chirurgie ist ein sinnvoller Ansatz zur Verbesserung der Prognose beim Magenkarzinom. Als perioperatives Konzept hat sich in Deutschland und zunehmend auch international das FLOT-Regime (5-Fluorouracil, Leucovorin, Oxaliplatin, Docetaxel) etabliert. Der prognostische Stellenwert der neoadjuvanten Radiochemotherapie bleibt anhand der gegenwärtig aktiven Studien abzuwarten. Bedeutung für die Entscheidungsprozesse im Tumorboard hat zunehmend der MSI-Status (Mikrosatelliteninstabilität) gewonnen, wobei Patienten mit MSI-Tumoren möglicherweise nicht von einer neoadjuvanten Chemotherapie profitieren. Patienten mit nur beginnend lokal fortgeschrittenen MSI-Tumoren (cT2, N0) oder solchen mit Komorbiditäten könnte eine neoadjuvante Therapie erspart bleiben. Die vorliegende Arbeit setzt sich kritisch mit den aktuellen „State-of-the-art“-Konzepten sowie den laufenden Studien zur neoadjuvanten bzw. perioperativen Therapie des Magenkarzinoms auseinander. Hierzu werden die wesentlichen, bereits publizierten und die aktiven Studien dargestellt.
Abstract
Neoadjuvant or perioperative therapy with radical surgery is a meaningful approach to improve the prognosis of gastric cancer. The FLOT regimen (5-fluorouracil, leucovorin, oxaliplatin, docetaxel) has been established as a perioperative concept in Germany and is also increasingly being used internationally. The prognostic significance of neoadjuvant chemoradiotherapy has to be awaited based on the results of currently active studies. The microsatellite instability (MSI) status has increasingly gained in importance with respect to decision-making processes in the interdisciplinary tumor board as patients with MSI tumors probably do not benefit from neoadjuvant therapy. Patients with only initial stages of locally advanced MSI tumors (cT2, N0) and those with comorbidities could be spared from neoadjuvant therapy. This article critically deals with the current state of the art concepts as well as with ongoing studies with respect to neoadjuvant and perioperative treatment of gastric cancer. For this purpose, the essential already published and the active studies are presented.
