Pre-treatment levels of inflammatory markers and chemotherapy completion rates in patients with early-stage breast cancer
Background Chemotherapy efcacy is largely dependent on treatment adherence, defned by the relative dose intensity (RDI). Identifcation of new modifable risk factors associated with low RDI might improve chemotherapy delivery. Here, we evaluated the association between low RDI and pre-chemotherapy fa...

Methods This exploratory analysis assessed data from 267 patients with early-stage breast cancer scheduled to undergo (neo-)adjuvant chemotherapy included in the Physical training and Cancer (Phys-Can) trial. The association between low RDI, defned as<85%, patient-related (age, body mass index, co-morbid condition, body surface area) and treatment-related factors (cancer stage, receptor status, chemotherapy duration, chemotherapy dose, granulocyte colony-stimulating factor) was investigated. Analyses further included the association between RDI and pre-chemotherapy levels of interleukin (IL)-6, IL-8, IL-10, C-reactive protein (CRP) and Tumor Necrosis Factor-alpha (TNF-α) in 172 patients with available blood samples. Results An RDI of<85% occurred in 31 patients (12%). Univariable analysis revealed a signifcant association with a chemotherapy duration above 20 weeks (p<0.001), chemotherapy dose (p=0.006), pre-chemotherapy IL-8 (OR 1.61; 95% CI (1.01; 2.58); p=0.040) and TNF-α (OR 2.2 (1.17; 4.53); p=0.019). In multivariable analyses, infammatory cytokines were signifcant association with low RDI for IL-8 (OR: 1.65 [0.99; 2.69]; p=0.044) and TNF-α (OR 2.95 [1.41; 7.19]; p=0.007). Conclusions This exploratory analysis highlights the association of pre-chemotherapy IL-8 and TNF-α with low RDI of chemotherapy for breast cancer. IL-8 and TNF-α may therefore potentially help to identify patients at risk for experiencing dose reductions.</description><language>eng</language><subject>breast cancer ; chemotherapy ; interleukin-8 ; relative dose intensity ; tumor necrosis factor-alpha</subject><creationdate>2022</creationdate><rights>info:eu-repo/semantics/openAccess</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,780,885,26567</link.rule.ids><linktorsrc>$$Uhttp://hdl.handle.net/11250/3098564$$EView_record_in_NORA$$FView_record_in_$$GNORA$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>Schauer, Tim</creatorcontrib><creatorcontrib>Henriksson, Anna</creatorcontrib><creatorcontrib>Strandberg, Emelie</creatorcontrib><creatorcontrib>Lindman, Henrik</creatorcontrib><creatorcontrib>Berntsen, Sveinung</creatorcontrib><creatorcontrib>Demmelmaier, Ingrid</creatorcontrib><creatorcontrib>Raastad, Truls</creatorcontrib><creatorcontrib>Nordin, Karin</creatorcontrib><creatorcontrib>Christensen, Jesper F</creatorcontrib><title>Pre-treatment levels of inflammatory markers and chemotherapy completion rates in patients with early-stage breast cancer</title><description>Background Chemotherapy efcacy is largely dependent on treatment adherence, defned by the relative dose intensity (RDI).
