Although the incidence of gastric cancer has been decreasing in the world and in Slovenia, it is still a major cause of cancer mortality. The prognosis is poor, since the disease is often detected at an advanced stage. Treatment results can be improved only by early detection. A multidisciplinary approach is a very important part of treatment, but the main role is still played by surgery. We describe the current principles of surgical treatment: the extent of resection in all three dimensions (on the organ itself, on neighbouring structures and organs or their parts), the extent of lymphadenectomy and the reconstruction methods.Čeprav incidenca raka želodca po svetu in pri nas upada, je še vedno pomemben vzrok umrljivosti zaradi raka. Prognoza je slaba, ker je bolezen odkrita pogosto v napredovalem stadiju. Rezultate zdravljenja je mogoče izboljšati le z zgodnejšim odkrivanjem. V zdravljenju je pomemben multidisciplinarni pristop. Glavno vlogo v zdravljenju ima še vedno kirurgija. Opisana so današnja načela kirurškega zdravljenja: obseg resekcije v vseh treh dimenzijah (na organu samem, sosednjih strukturah oziroma sosednjih organih ali njihovih delih), obseg limfadenektomije in načini rekonstrukcije
