Methods: We retrospectively analyzed twenty-six consecutive patients who had been treated at our center with CIRT for high-risk NPC between 2009 and 2018. Carbon ion (C12) boost was applied in a bimodal setting combined with intensity-modulated radiotherapy (IMRT) base plan. The median cumulative total dose was 74 Gy (RBE), and patients with inoperable (n = 17, 65%) or incompletely resected (n = 7, 27%) tumors were included in the analysis. Overall, 81% received concomitant chemotherapy (n = 21). Results: The median follow-up time was 40 months (range 10⁻97 months) for all patients. At the last follow-up, 92% of the patients were still alive. We could identify excellent tumor response with complete tumor remission (CR) in 60% (n = 15/25), partial tumor remission (PR) in 20% (n = 5/25), and stable disease (SD) in 12% (n = 3/25) of the patients according to the RECIST (Response Evaluation Criteria in Solid Tumors) criteria. Despite unfavorable tumor characteristics, only one patient showed a locally in-field recurrence after 56 months (4%) and another patient a locoregional recurrence in the unilateral cervical lymph nodes after 21 months (4%). The 2-year local control (LC), distant progression-free survival (DPFS), and overall survival (OS) were 95%, 93%, and 100% and the estimated 5-year LC, DPFS, and OS were 90%, 86%, and 86%, respectively. Overall, treatment was tolerated well with 20% acute and 16% chronic grade 3 side effects. No toxicity greater than grade 3 occurred. Conclusion: Bimodal radiotherapy including IMRT and active raster-scanning CIRT for high-risk nasopharyngeal cancer is a safe treatment method resulting in moderate toxicity and excellent local control. A larger patient number and longer follow-up time would be necessary to strengthen the current findings. 000143371 536__ $$0G:(DE-HGF)POF3-315$$a315 - Imaging and radiooncology (POF3-315)$$cPOF3-315$$fPOF III$$x0 000143371 588__ $$aDataset connected to CrossRef, PubMed, 000143371 7001_ $$aHeld, Thomas$$b1 000143371 7001_ $$aLang, Kristin$$b2 000143371 7001_ $$aForster, Tobias$$b3 000143371 7001_ $$00000-0002-2537-0185$$aFederspil, Philippe$$b4 000143371 7001_ $$0P:(DE-HGF)0$$aHerfarth, Klaus$$b5 000143371 7001_ $$aHäfner, Matthias$$b6 000143371 7001_ $$aPlinkert, Peter$$b7 000143371 7001_ $$0P:(DE-HGF)0$$aRieken, Stefan$$b8 000143371 7001_ $$0P:(DE-He78)8714da4e45acfa36ce87c291443a9218$$aDebus, Jürgen$$b9$$udkfz 000143371 7001_ $$00000-0001-8463-514X$$aAdeberg, Sebastian$$b10 000143371 773__ $$0PERI:(DE-600)2527080-1$$a10.3390/cancers11030379$$gVol. 11, no. 3, p. 379 -$$n3$$p379 -$$tCancers$$v11$$x2072-6694$$y2019 000143371 909CO $$ooai:inrepo02.dkfz.de:143371$$pVDB 000143371 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b5$$kDKFZ 000143371 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-HGF)0$$aDeutsches Krebsforschungszentrum$$b8$$kDKFZ 000143371 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)8714da4e45acfa36ce87c291443a9218$$aDeutsches Krebsforschungszentrum$$b9$$kDKFZ 000143371 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 000143371 9141_ $$y2019 000143371 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCANCERS : 2017 000143371 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000143371 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000143371 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000143371 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000143371 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000143371 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000143371 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review 000143371 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ 000143371 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000143371 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000143371 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000143371 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000143371 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000143371 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000143371 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bCANCERS : 2017 000143371 9201_ $$0I:(DE-He78)E050-20160331$$kE050$$lKKE Strahlentherapie$$x0 000143371 980__ $$ajournal 000143371 980__ $$aVDB 000143371 980__ $$aI:(DE-He78)E050-20160331 000143371 980__ $$aUNRESTRICTED
