Introduction: Ki67 value and its variation before and after neoadjuvant chemotherapy are commonly tested in relation to breast cancer patient prognosis. This study aims to quantify the extent of changes in Ki67 proliferation pre- and post-neoadjuvant chemotherapy, confirm an optimal cut-off point, and evaluate its potential value for predicting survival outcomes in patients with different molecular subtypes of breast cancer.Methods: This retrospective real-world study recruited 828 patients at the Department of Breast Surgery of the First Affiliated Hospital of China Medical University and the Cancer Hospital of China Medical University from Jan 2014 to Nov 2020. Patient demographic features and disease pathology characteristics were recorded, and biomarkers were verified through immunohistochemistry. Various statistical methods were used to validate the relationships between different characteristics and survival outcomes irrespective of disease-free and overall survival.Results: Among 828 patients, statistically significant effects between pathological complete response and survival outcome were found in both HER2-enriched and triple-negative breast cancer (p &lt; 0.05) but not in Luminal breast cancer (p &gt; 0.05). Evident decrease of Ki67 was confirmed after neoadjuvant chemotherapy. To quantify the extent of Ki67 changes between pre- and post-NAC timepoints, we adopted a computational equation termed ΔKi67% for research. We found the optimal cut-off value to be “ΔKi67% = −63%” via the operating characteristic curve, defining ΔKi67% ≤ −63% as positive status and ΔKi67% &gt; −63% as negative status. Patients with positive ΔKi67% status were 37.1% of the entire cohort. Additionally, 4.7, 39.9, 34.5 and 39.6% of patients with Luminal A, Luminal B, HER2-enriched and triple negative breast cancer were also validated with positive ΔKi67% status. The statistically significant differences between ΔKi67% status and prognostic outcomes were confirmed by univariate and multivariate analysis in Luminal B (univariate and multivariate analysis: p &lt; 0.05) and triple negative breast cancer (univariate and multivariate analysis: p &lt; 0.05). We proved ΔKi67% as a statistically significant independent prognostic factor irrespective of disease-free or overall survival among patients with Luminal B and triple-negative breast cancer.Conclusions:ΔKi67% can aid in predicting patient prognostic outcome, provide a measurement of NAC efficacy, and assist in further clinical decisions, especially for patients with Luminal B breast cancer.

158 Background: Triple-negative breast cancer (TNBC) is a unique subtype and consider as an aggressive disease without established targeted treatment options. This study conducted to determine the incidence, characteristics, and survival outcomes of TNBC patients in an Egyptian cancer institute. Methods: Medical records of 520 patients treated between 2010-2011 in Clinical Oncology Department-Ain Shams University-Egypt were analyzed. Cox proportional hazards models were used to evaluate the association between TNBC and DFS and OS after adjusting for other covariates. Results: Among the 520 patients, 139 were TNBC .The median age was 50 years (SD±11.767, Range 20-80 ) versus 52 years (SD±12.134, Range 20-80), median tumor diameter was 5 cm (SD± 1.408, Range 1-7) versus was 5 cm (SD± 1.401, Range 1-7) , and median number of positive axillary LN was 3 (SD± 4.779, Range 0-37) versus 3 (SD± 4.832, Range 0-25) in non TNBC and TNBC respectively . Median disease-free survival was 24 months (SD± 14.128, Range 1-69 ) versus 15 months (SD± 8.811, Range 1-43 ) and median overall survival was 41 months (SD± 16.249, Range 3-60) versus 31 months (SD± 12.184, Range 7-60 ) in non TNBC and TNBC respectively. About 85.6 % of the TNBC tumors were IDC, 4.4 % were ILC and 5% were mixed. About 1.4 % of the TNBC tumors were grade I, 70.5 % were grade II and 28.1% were grade III. Median disease-free survival was 24 months (95%CI 21.679- 26.321) versus 15 months (95%CI 12.587-17.413) (p< 0.001) and median overall survival was 44 months (95%CI 41.396-46.604) versus 31 months (95%CI 29.460-32.540) (p< 0.001) in non TNBC and TNBC respectively. In TNBC cohort , DFS was 12 months (95%CI 11.464-12.536) in patients with grade III tumors versus 25 months (95%CI 22.359-27.641 )in patients with other grades (p< 0.001), this was also reflected in OS as 29 months (95%CI 25.129-32.871 ) versus 44 months (95%CI 41.238-46.762 ) (p< 0.001). Conclusions: Multivariate analyses supported a conclusion that TNBC subtype was an independent adverse prognostic factor for survival along with other known risk factors such as tumor grade.

AbstractBrian metastasis, which is diagnosed in 30% of triple-negative breast cancer (TNBC) patients with metastasis, causes poor survival outcomes. Growing evidence has characterized miRNAs involving in breast cancer brain metastasis; however, currently, there is a lack of prognostic plasma-based indicator for brain metastasis. In this study, high level of miR-211 can act as brain metastatic prognostic marker in vivo. High miR-211 drives early and specific brain colonization through enhancing trans-blood–brain barrier (BBB) migration, BBB adherence, and stemness properties of tumor cells and causes poor survival in vivo. SOX11 and NGN2 are the downstream targets of miR-211 and negatively regulate miR-211-mediated TNBC brain metastasis in vitro and in vivo. Most importantly, high miR-211 is correlated with poor survival and brain metastasis in TNBC patients. Our findings suggest that miR-211 may be used as an indicator for TNBC brain metastasis.

Somatic Alteration

This study aimed to clarify the genetic difference between Korean triple-negative breast cancer (TNBC) and other breast cancer (BC) subtypes. TNBC was defined as the absence of hormonal receptors and human epidermal growth factor receptor 2 (HER2) amplification. DNA panel of the Ion Torrent Oncomine Comprehensive Assay (OCA) v3 was performed to identify somatic alteration in 48 specimens. In a total of 102 alterations (37 nonsense, 35 missense, 8 frameshift and 22 amplifications), 30 nucleotide alterations (24 nonsense, 1 missense, and 5 frameshift) were newly identified. The eight most commonly altered genes were PIK3CA, TP53, ERBB2, BRCA2, FANCD2, AKT1, BRCA1, and FANCA. TNBC had significantly lower mutation frequency in PIK3CA (TNBC vs. hormone receptor-positive and HER2-negative BC [HRPBC], p = 0.009), but higher mutation frequency in TP53 (TNBC vs. HRPBC, p = 0.036; TNBC vs. hormone receptor-positive and HER2- positive BC [HHPBC], p = 0.004). TNBC showed frequently higher Ki-67 expression than any positive BC (p = 0.004) due to HRPBC (p < 0.001). TNBC with high Ki-67/unmutated PIK3CA/mutated TP53 appears at a younger age (52.2 ± 7.6 years), compared to other subtypes (63.7 ± 11.0 years). TNBC with high Ki-67/unmutated PIK3CA/mutated TP53 may be related to relatively early onset BCThese findings demonstrate the genomic heterogeneity between TNBC and other BC subtypes and could present a new approach for molecular targeted therapy in TNBC patients.
