IntroductionBreast-cancer is a common-cause of death in women.(1) We investigated the effects of before/after-NACT on hemoglobin-albumin-lymphocyte-platelet (HALP) scores and of changes therein on clinical/pathological-responses.Materials And MethodsOne-hundred-twenty-seven breast-cancer-patients receiving-NACT between December 2009 - January 2019 were investigated retrospectively.ResultsThe mean - age was 50.3±12.3 (min 27 - max 79), and 125 patients (98.4 %) were women. Fifty-four (42.5 %) were premenopausal and 71 (55.9 %) postmenopausal. Invasive-ductal-carcinoma was present in 111 patients (92.5 %). Eighty patients (70.2 %) were ≤ T2 and 34 (29.8 %) > T2. Lymph-node-status was positive in 99 patients (83.2 %) and negative in 20 (16.8 %). Ki-67 was ≤ 10 % in 22 (28.9 %), 11-20 % in 23 (30.3 %), and > 20 % in 31 (40.8 %). Complete clinical response was observed in 27 (21.3 %), partial-response in 76 (59.8 %), stable-disease in 21 (16.5 %), and progressive-disease in 3 patients (2.4 %). The objective-response-rate (ORR) was 103 (81.1 %). Pathological-complete-response (pCR) was observed in 24 patients (18.9 %). ORR was higher in Ki-67 > 20 % compared to ≤ 10 % and 10-20 % (90.3 % vs 59.0 % / 78.3 %, respectively, p: 0.027), but no difference occurred in pCR. Neutrophil-lymphocyte-ratio (NLR), platelet-lymphocyte-ratio (PLR), prognostic-nutritional-index (PNI), and HALP were measured before/after NACT. Associations with ORR and pCR were investigated via changes in these with NACT (excepting-PNI), but no-significant results emerged.ConclusionsHigher ORR occurred post-NACT in patients with Ki-67 >20 %, while NLR, PLR, PNI, and HALP before/after-NACT and post-NACT-changes (excepting-PNI) had no-effect on ORR/pCR (Tab. 5, Ref. 21).
