Zusammenfassung
Das Magenkarzinom ist ein aggressiver Tumor, der aufgrund spät auftretender Symptomatik insgesamt mit einer schlechten Prognose einhergeht. Während das Magenfrühkarzinom durch endoskopische Abtragung behandelt werden kann, zeigten zahlreiche Studien, dass beim lokal fortgeschrittenen Magenkarzinom eine perioperative Chemotherapie die Prognose deutlich verbessert. Die chirurgische Therapie umfasst die subtotale bzw. totale Magenresektion mit Lymphadenektomie der Kompartimente 1 und 2 (D2). Eine zusätzliche Splenektomie oder Pankreasschwanzresektion erhöht die Morbidität und sollte vermieden werden. Bei fehlender Resektabilität kann eine palliative Chemotherapie (in Kombination mit Trastuzumab bei positivem HER2-Status) die Prognose verbessern. Zur Verbesserung der Lebensqualität sind endoskopische oder ggf. operative Verfahren geeignet. Die Nachsorge nach onkologischer Behandlung erfolgt symptomorientiert, eine regelmäßige Vitamin-B12-Substitution ist essenziell.
Abstract
Gastric cancer is a very aggressive tumor. Due to the late onset of symptoms most tumors are diagnosed in an advanced stage. For early gastric cancer endoscopic resection is a well-established treatment. In case of locally advanced tumor stage several studies have shown a significant survival benefit for perioperative chemotherapy. Surgical treatment includes subtotal or total gastric resection with radical lymphadenectomy of lymph node groups of both compartments 1 and 2. An additional splenectomy or distal pancreatic resection should be avoided to reduce postoperative morbidity. In case of non-resectable tumor palliative chemotherapy can improve the prognosis (combined with trastuzumab in case of a positive HER2 status). For improvement of quality of life endoscopic or surgical procedures can be offered. Follow-up is only clinically oriented with the need for regular vitamin B12 substitution.
