However, two randomised trials showed lower acute toxicity in prone position. Furthermore, in most patients, prone positioning reduced doses to the organs at risk. To confirm these findings, we compared toxicity outcomes, photographic assessment, and dosimetry between both positions using REQUITE data.REQUITE is an international multi-centre prospective observational study that recruited 2069 breast cancer patients receiving radiotherapy. Data on toxicity, health-related quality of life (HRQoL), and dosimetry were collected, as well as a photographic assessment. A matched case control analysis compared patients treated prone (n = 268) versus supine (n = 493). Exact matching was performed for the use of intensity-modulated radiotherapy, boost, lymph node irradiation, chemotherapy and fractionation, and the nearest neighbour for breast volume. Primary endpoints were dermatitis at the end of radiotherapy, and atrophy and cosmetic outcome by photographic assessment at two years.At the last treatment fraction, there was no significant difference in dermatitis (p = .28) or any HRQoL domain, but prone positioning increased the risk of breast oedema (p < .001). At 2 years, patients treated in prone position had less atrophy (p = .01), and higher body image (p < .001), and social functioning (p < .001) scores. The photographic assessment showed no difference in cosmesis at 2 years (p = .22). In prone position, mean heart dose (MHD) was significantly lower for left-sided patients (1.29 Gy vs 2.10 Gy, p < .001) and ipsilateral mean lung dose (MLD) was significantly lower for all patients (2.77 Gy vs 5.89 Gy, p < .001).Prone radiotherapy showed lower MLD and MHD compared to supine position, although the risk of developing breast oedema during radiotherapy was higher. At 2 years the photographic assessment showed no difference in the cosmetic outcome, but less atrophy was seen in prone-treated patients and this seems to have a positive influence on the HRQoL domain of body image. 000278339 536__ $$0G:(DE-HGF)POF4-313$$a313 - Krebsrisikofaktoren und Prävention (POF4-313)$$cPOF4-313$$fPOF IV$$x0 000278339 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000278339 650_7 $$2Other$$aBreast cancer 000278339 650_7 $$2Other$$adosimetry 000278339 650_7 $$2Other$$ahealth-related quality of life 000278339 650_7 $$2Other$$aprone position 000278339 650_7 $$2Other$$aradiotherapy toxicity 000278339 7001_ $$00000-0002-4867-9847$$aDeseyne, Pieter$$b1 000278339 7001_ $$aBultijnck, Renée$$b2 000278339 7001_ $$aPost, Giselle$$b3 000278339 7001_ $$aWest, Catharine$$b4 000278339 7001_ $$aAzria, David$$b5 000278339 7001_ $$aBourgier, Celine$$b6 000278339 7001_ $$aFarcy-Jacquet, Marie-Pierre$$b7 000278339 7001_ $$aRosenstein, Barry$$b8 000278339 7001_ $$aGreen, Sheryl$$b9 000278339 7001_ $$ade Ruysscher, Dirk$$b10 000278339 7001_ $$aSperk, Elena$$b11 000278339 7001_ $$aVeldwijk, Marlon$$b12 000278339 7001_ $$aHerskind, Carsten$$b13 000278339 7001_ $$aDe Santis, Maria Carmen$$b14 000278339 7001_ $$aRancati, Tiziana$$b15 000278339 7001_ $$aGiandini, Tommaso$$b16 000278339 7001_ $$0P:(DE-He78)c259d6cc99edf5c7bc7ce22c7f87c253$$aChang-Claude, Jenny$$b17$$udkfz 000278339 7001_ $$0P:(DE-He78)fd17a8dbf8d08ea5bb656dfef7398215$$aSeibold, Petra$$b18$$udkfz 000278339 7001_ $$aLambrecht, Maarten$$b19 000278339 7001_ $$aWeltens, Caroline$$b20 000278339 7001_ $$aJanssens, Hilde$$b21 000278339 7001_ $$aVega, Ana$$b22 000278339 7001_ $$aTaboada-Valladares, Maria Begoña$$b23 000278339 7001_ $$00000-0002-7822-6726$$aAguado-Barrera, Miguel Elías$$b24 000278339 7001_ $$aReyes, Victoria$$b25 000278339 7001_ $$aAltabas, Manuel$$b26 000278339 7001_ $$aGutiérrez-Enríquez, Sara$$b27 000278339 7001_ $$aMonten, Christel$$b28 000278339 7001_ $$aVan Hulle, Hans$$b29 000278339 7001_ $$aVeldeman, Liv$$b30 000278339 773__ $$0PERI:(DE-600)1492623-4$$a10.1080/0284186X.2023.2240486$$gp. 1 - 9$$n9$$p1036-1044$$tActa oncologica$$v62$$x0284-186X$$y2023 000278339 909CO $$ooai:inrepo02.dkfz.de:278339$$pVDB 000278339 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)c259d6cc99edf5c7bc7ce22c7f87c253$$aDeutsches Krebsforschungszentrum$$b17$$kDKFZ 000278339 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)fd17a8dbf8d08ea5bb656dfef7398215$$aDeutsches Krebsforschungszentrum$$b18$$kDKFZ 000278339 9131_ $$0G:(DE-HGF)POF4-313$$1G:(DE-HGF)POF4-310$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vKrebsrisikofaktoren und Prävention$$x0 000278339 9141_ $$y2023 000278339 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2022-11-12 000278339 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2022-11-12 000278339 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2022-11-12 000278339 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2023-10-21$$wger 000278339 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bACTA ONCOL : 2022$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2023-10-21 000278339 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2023-10-21 000278339 9201_ $$0I:(DE-He78)C020-20160331$$kC020$$lC020 Epidemiologie von Krebs$$x0 000278339 980__ $$ajournal 000278339 980__ $$aVDB 000278339 980__ $$aI:(DE-He78)C020-20160331 000278339 980__ $$aUNRESTRICTED
