This is highly relevant in patients with pancreatic cancer, where organs at risk lie in close proximity to the target.Data sets of 10 patients with locally advanced pancreatic cancer were evaluated. Gross tumor volume deformation was analyzed. Dose changes to organs at risk were determined with focus on kidneys both without adaptive radiotherapy compensation and with replanning based on weekly acquired computed tomography scans.During irradiation, gross tumor volume changes between 0% and 26% and moves within a radius of 5 to 16 mm. Required maximal dose to organs at risk for kidneys can be met with the current practice of matching computed tomography scans during treatment and adjusting patient position accordingly. Comparison of the mean doses and V15, V20 volumes demonstrated that weekly replanning could bring a significant dose sparing of the left kidney.Manual matching with focus on bony structures can lead to overall acceptable positioning of patients during treatment. Thus, tolerance doses of organs at risk, such as the kidneys, can be met. With adequate margins, normal tissue constraints to organs at risk can be kept as well. Adaptive radiotherapy approaches (in this case with weekly rescanning) reduced dose to organs at risk, which may be especially important for hypofractionated approaches. 000128883 536__ $$0G:(DE-HGF)POF3-315$$a315 - Imaging and radiooncology (POF3-315)$$cPOF3-315$$fPOF III$$x0 000128883 588__ $$aDataset connected to CrossRef, PubMed, 000128883 7001_ $$0P:(DE-HGF)0$$aJäger, Andreas$$b1 000128883 7001_ $$aHabermehl, Daniel$$b2 000128883 7001_ $$0P:(DE-HGF)0$$aRüppell, Jan$$b3 000128883 7001_ $$0P:(DE-He78)4e7bb332499544552cf19660bec6f04f$$aBendl, Rolf$$b4$$udkfz 000128883 7001_ $$0P:(DE-He78)8714da4e45acfa36ce87c291443a9218$$aDebus, Jürgen$$b5$$udkfz 000128883 7001_ $$aCombs, Stephanie E$$b6 000128883 773__ $$0PERI:(DE-600)2220436-2$$a10.1177/1533034615577515$$gVol. 15, no. 2, p. 348 - 354$$n2$$p348 - 354$$tTechnology in cancer research & treatment$$v15$$x1533-0338$$y2016 000128883 909CO $$ooai:inrepo02.dkfz.de:128883$$pVDB 000128883 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000128883 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000128883 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)4e7bb332499544552cf19660bec6f04f$$aDeutsches Krebsforschungszentrum$$b4$$kDKFZ 000128883 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)8714da4e45acfa36ce87c291443a9218$$aDeutsches Krebsforschungszentrum$$b5$$kDKFZ 000128883 9131_ $$0G:(DE-HGF)POF3-315$$1G:(DE-HGF)POF3-310$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vImaging and radiooncology$$x0 000128883 9141_ $$y2016 000128883 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000128883 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000128883 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bTECHNOL CANCER RES T : 2015 000128883 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000128883 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000128883 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000128883 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000128883 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine 000128883 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000128883 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000128883 9201_ $$0I:(DE-He78)E071-20160331$$kE071$$lSoftwareentwicklung für Integrierte Diagnostik und Therapie(SIDT)$$x0 000128883 9201_ $$0I:(DE-He78)E040-20160331$$kE040$$lMedizinische Physik in der Strahlentherapie$$x1 000128883 9201_ $$0I:(DE-He78)E050-20160331$$kE050$$lKKE Strahlentherapie$$x2 000128883 980__ $$ajournal 000128883 980__ $$aVDB 000128883 980__ $$aI:(DE-He78)E071-20160331 000128883 980__ $$aI:(DE-He78)E040-20160331 000128883 980__ $$aI:(DE-He78)E050-20160331 000128883 980__ $$aUNRESTRICTED
