5 Arbejdshypotese - Måske er det vanskelig at opnå op,mal nåleplacering/tumordække ved anatomisk komplicerede tumorer? - Måske modvirker blodcirkula,onen nedfrysningen af centrale/endofy,ske tumorer (heatpump effect)? Risikoen for behandlingssvigt ved laparoskopisk cryoabla.on s.ger i takt med en.ltagende PADUA score

12 Konklusion PADUA score findes signifikant forøget ved pa>enter som oplever inkomplet abla>on såvel som lokal recidiv eller metastase. Der er op mod 5 gange større risiko for inkomplet abla>on af en tumor med høj PADUA score, sammenlignet med en tumor med lav eller moderat PADUA score. Justeret for alder og tumorstørrelse findes der øget risiko for lokal recidiv eller metastase ved: PADUA score > Eksofy>sk komponent < 5% Central longitudinal placering Involvering af nyre-sinus
