Elfogadott ténynek számít, hogy a nem metastaticus rectumtumorok egyedüli preoperatív sugárterápiájával a lokálrecidíva-ráta 50%-kal csökkenthető. Beteganyag és módszer: 1990 és 2001 között 181 rectumtumoros betegnél végeztünk preoperatív célú 36 Gy, illetve 40 Gy dózisú irradiációt. A stádiumba sorolást a módosított Astler–Coller patológiai staging szisztéma szerint végeztük. A sugárkezelést telekobalt-készülékkel, illetve nagyenergiájú fotonbesugárzóval végeztük számítógépes besugárzástervezést követően. Eredmény: A preoperatív sugárkezelés eredményességének legfontosabb fokmérője a lokálrecidíva-ráta, mely anyagunkban 21,56%-os volt. Szignifikánsan befolyásolta a túlélést a beteg kora és az alkalmazott dózis nagysága. Következtetés: Rectumtumoros beteganyagunk statisztikai analízise az egyedüli preoperatív sugárkezelés hatékonyságát vizsgálta. Az eredmények megfeleltek az erre vonatkozó közleményekben közöltekkel.
