Während ein lokal begrenzter Tumor durch eine chirurgische Therapie oder – in ausgewählten Fällen – durch eine endoskopische Mukosaresektion optimal behandelt werden kann, liegt bei den meisten Patienten entweder wegen eines lokal fortgeschrittenen Tumors oder wegen Fernmetastasen ein Erkrankungsstadium vor, in dem eine kurative Resektion nicht möglich ist. Dann ist neben palliativen chirurgischen oder endoskopischen Maßnahmen eine systemische palliative Chemotherapie häufig die einzige Behandlungsoption. Basierend auf den Ergebnissen zweier großer europäischer Studien gilt die perioperative Chemotherapie mit dem Ziel der besseren lokalen Tumorkontrolle und der Therapie noch okkulter Fernmetastasen in Europa heute als Standard. Während in der palliativen Situation bisher die Kombinationstherapie mit Cisplatin und 5–Fluorouracil als Referenztherapie etabliert war, ist das Spektrum der möglichen Therapieoptionen heute deutlich größer. Oxaliplatin und Capecitabin sowie taxan– und irinotecanhaltige Schemata haben sich bei der Therapie des fortgeschrittenen Magenkarzinoms als wirksam erwiesen. Die zusätzliche Behandlung mit Inhibitoren der EGFR– und VEGF–Signalwege zeigt bislang in einarmigen Phase–II–Studien vielversprechende Ergebnisse, sollte aber außerhalb von Studien nicht zum Einsatz kommen. Nicht zuletzt bleibt aber eine optimale supportive Therapie von entscheidender Bedeutung.

In contrast to limited tumors that can be treated by surgical resection or – in well selected cases – by endoscopic mucosectomy, most of the patients with gastric cancer present either locally advanced stage or metastatic disease making curative resection impossible. In these cases, a systemic palliative chemotherapy is often the only available option for treatment besides palliative surgical or endoscopic techniques. Based on results of two large–scale European studies, a perioperative chemotherapy is considered as standard in Europe with respect to the aim of improved local tumor–control and therapy of occult distant metastases. So far the use of combined therapy with cisplatin and 5–FU was established as reference therapy, but the scale of palliative therapeutic options has been widened recently. Oxaliplatin and capecitabine as well as taxanes and irinotecan have been shown to be effective in the treatment of advanced gastric cancer. An additional therapy with inhibitors of the EGFR– and VEGF–pathways has shown promising results in early, single–armed studies, but should not be applied in a routine clinical setting. An optimal supportive care remains the basis of treatment of patients with advanced gastric cancer.
