Thus, low RILA values of T-lymphocyte subpopulations have been associated with increased risk for various endpoints at 2 to 3 years of follow-up. The purpose was to test if such associations persist for specific endpoints (subcutaneous fibrosis, telangiectasia) in breast cancer patients with at least 10 years of follow-up.Experimental Design: Two hundred and seventy-two female patients who had received breast-conserving therapy within the German ISE study were included (median follow-up: 11.6 years). Radiotherapy-induced side effects were scored according to the Late Effects in Normal Tissues-Subjective, Objective, Management, and Analytic (LENT-SOMA) classification system. RILA in the CD4+, CD8+, and natural killer (NK) subpopulations from peripheral blood was analyzed by flow cytometry. Multivariate predictive modeling was performed including relevant clinical risk factors.Low CD4+ RILA was associated with increased risk for both fibrosis (P = 0.011) and telangiectasia (P < 0.001). For fibrosis, the association was stronger outside the surgical area (Fibout; P = 0.004) than within (Fibin; P = 0.17). Predictive multivariate modeling including clinical risk factors yielded OR of 3.48 (95% confidence interval, 1.84-6.58) for any fibrosis and 8.60 (2.71-27.3) for telangiectasia. Addition of CD4+ RILA to the clinical variables improved discrimination (c statistics) from 0.62 to 0.68 for any fibrosis, 0.62 to 0.66 for Fibin, 0.61 to 0.69 for Fibout, and from 0.65 to 0.76 for telangiectasia. CD8+ and NK RILA were not significantly associated with radiotherapy-related late reactions.The results provide first evidence that low CD4+ RILA is associated with increased subcutaneous fibrosis and telangiectasia even after 10 years. This supports the potential usefulness for predicting individual clinical risk. 000142878 536__ $$0G:(DE-HGF)POF3-313$$a313 - Cancer risk factors and prevention (POF3-313)$$cPOF3-313$$fPOF III$$x0 000142878 588__ $$aDataset connected to CrossRef, PubMed, 000142878 7001_ $$0P:(DE-He78)fd17a8dbf8d08ea5bb656dfef7398215$$aSeibold, Petra$$b1 000142878 7001_ $$0P:(DE-He78)5444d70823957b5081dfd421dbfed155$$aBotma, Akke$$b2 000142878 7001_ $$0P:(DE-He78)6463d23a85ce9e7ecc93b32fc2b4d25f$$aHelmbold, Irmgard$$b3 000142878 7001_ $$aSperk, Elena$$b4 000142878 7001_ $$aGiordano, Frank A$$b5 000142878 7001_ $$aGürth, Nicole$$b6 000142878 7001_ $$aKirchner, Anne$$b7 000142878 7001_ $$aBehrens, Sabine$$b8 000142878 7001_ $$00000-0001-6037-0853$$aWenz, Frederik$$b9 000142878 7001_ $$0P:(DE-He78)c259d6cc99edf5c7bc7ce22c7f87c253$$aChang-Claude, Jenny$$b10$$eLast author 000142878 7001_ $$00000-0001-6554-5907$$aHerskind, Carsten$$b11 000142878 773__ $$0PERI:(DE-600)2036787-9$$a10.1158/1078-0432.CCR-18-0777$$gVol. 25, no. 2, p. 562 - 572$$n2$$p562 - 572$$tClinical cancer research$$v25$$x1557-3265$$y2019 000142878 909CO $$ooai:inrepo02.dkfz.de:142878$$pVDB 000142878 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)fd17a8dbf8d08ea5bb656dfef7398215$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000142878 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)5444d70823957b5081dfd421dbfed155$$aDeutsches Krebsforschungszentrum$$b2$$kDKFZ 000142878 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)6463d23a85ce9e7ecc93b32fc2b4d25f$$aDeutsches Krebsforschungszentrum$$b3$$kDKFZ 000142878 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)c259d6cc99edf5c7bc7ce22c7f87c253$$aDeutsches Krebsforschungszentrum$$b10$$kDKFZ 000142878 9131_ $$0G:(DE-HGF)POF3-313$$1G:(DE-HGF)POF3-310$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vCancer risk factors and prevention$$x0 000142878 9141_ $$y2019 000142878 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bCLIN CANCER RES : 2017 000142878 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000142878 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000142878 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000142878 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000142878 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000142878 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000142878 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000142878 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine 000142878 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000142878 915__ $$0StatID:(DE-HGF)9910$$2StatID$$aIF >= 10$$bCLIN CANCER RES : 2017 000142878 9201_ $$0I:(DE-He78)C020-20160331$$kC020$$lC020 Epidemiologie von Krebs$$x0 000142878 980__ $$ajournal 000142878 980__ $$aVDB 000142878 980__ $$aI:(DE-He78)C020-20160331 000142878 980__ $$aUNRESTRICTED
