89 Background: Ki-67 expression in breast cancer has been described as predictive of pathological complete response and prognostic of recurrence free survival (RFS). Our aim was to evaluate in a retrospective cohort of triple negative breast cancer patients if tumor proliferation measured by ki-67 expression is correlated with the outcome. Methods: We evaluated a retrospective cohort of 109 cases of triple negative breast cancer (ER-, PR- and HER2- determined by immunohistochemistry). Ki-67 labeling index was determined in Formalin-Fixed, Paraffin-Embedded residual tumors after neoadjuvant chemotherapy. Patients were stratified in Ki67<15% and Ki67≥15%. Clinicopathological data was retrieved from clinical records. RFS and overall survival (OS) were calculated using the Kaplan–Meier method and variables compared using the log-rank or Breslow test and Hazard Ratios (HR) estimated by the Cox regression. Results: The median age for patients was 47.5 years, 55 (50.5%) were premenopausal and 54 (49.5%) postmenopausal. Eight patients (7.3%) were clinical stages II and 101 (92.7%) stages III. Median of Ki-67 expression was 35.97% (0.96% - 77.7%). There was not association between Ki-67 expression (<15% VS ≥15%) with tumor size, nodal involvement, clinical stage and menopausal status. After a median of follow of 21.6 months, 62 patients (56.9%) have relapsed and 53 (48.6%) have die. The median time for RFS and OS were 21.2 and 31.4 months, respectively. Median of RFS was 12.6 months for Ki67<15% vs 21.2 months for Ki67≥15%, P=0.421 (HR=0.91). Median of OS was 34.9 months for Ki67<15% vs 31.4 months for Ki67≥15%, P=0.755 (HR=1.18). Only nodal involvement was found predictor of shorter RFS (0 nodes, 25.2 months vs 1 -3 nodes, 26.1 months, vs >3 nodes, 9.4 months, P=0.020). Conclusions: Ki-67 labeling index was not related with the outcome in terms of OS and RFS in patients with residual triple negative breast tumors that were treated with neoadjuvant chemotherapy.

Women diagnosed with triple negative breast cancer can benefit neither from endocrine therapy nor from HER2-targeted therapies (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding mitochondrial ribosomal protein L13, MRPL13, when comparing the tumor cells of patients with triple negative breast cancer to normal mammary ductal cells (2). MRPL13 was also differentially expressed in bulk tumor in human breast cancer (3). MRPL13 mRNA was present at significantly increased quantities in TNBC tumor cells relative to normal mammary ductal cells. Analysis of human survival data revealed that expression of MRPL13 in primary tumors of the breast was correlated with recurrence-free survival in patients with basal-like, luminal A, luminal B and HER2+ type cancer, while within triple negative breast cancer, primary tumor expression of MRPL13 was correlated with recurrence-free survival in patients with basal-like 1 subtype disease. MRPL13 may be of relevance to initiation, maintenance or progression of triple negative breast cancers.

542 Background: Opioid-induced immunomodulation may be of particular importance in triple negative breast cancer (TNBC) where an immune response is associated with improved outcome and response to immunotherapy. We evaluated the association between intraoperative opioids and outcomes in a large TNBC cohort. Methods: Consecutive patients with stage I-III primary TNBC treated between 03/2010 and 12/2016 were identified from our prospectively maintained database. Total intraoperative opioid dose was extracted from anesthetic records and converted to oral morphine milligram equivalents (MME) (10 MME = 50 mcg fentanyl IV). Univariable and multivariable (MVA) Cox proportional hazards analysis (adjusting for relevant clinicopathological features, (neo)adjuvant therapy, anesthesia technique and morbidity score), were performed to quantify the association between opioid exposure and recurrence-free survival (RFS) and overall survival (OS). Results: 1143 patients were included. Median age was 54 years (IQR 45, 64). 911 (80%) had ductal histology, 359 (31%) had nodal metastases, and 1070 (94%) were poorly differentiated. 781 (68%) received adjuvant chemotherapy and 313 (27%) received neoadjuvant chemotherapy. 525 (46%) received total intravenous anesthesia and 618 (54%) had general anesthesia. Median intraoperative opioid dose was 30 MME (IQR 20, 60). 5-year RFS was 81% (95% CI 79%-84%), 5-year OS was 86% (95% CI 84%-88%). In MVA, higher opioid administration was associated with favorable RFS but did not significantly affect OS (Table). Conclusions: Our study is the first to directly evaluate intraoperative opioid administration in TNBC and suggests a protective effect on RFS. Future work will focus on elucidating the underlying mechanism for this effect, including possible modulation of endogenous opioid signaling pathways and immunologic correlates. [Table: see text]

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of transmembrane protease, serine 7, encoded by TMPRSS7 when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, TMPRSS7 expression was correlated with recurrence-free survival in patients with breast cancer. TMPRSS7 may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of keratin associated protein 21-1, encoded by KRTAP21-1 when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, KRTAP21-1 expression was correlated with recurrence-free survival inpatients with breast cancer. KRTAP21-1 may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.

Objective Clinical and pathological characteristics of triple negative breast cancer (TNBC) treatment are required for escalation or de-escalation of treatment because of a lack of druggable targets. This study aimed to identify the factors affecting the risk of disease recurrence and disease-related death in patients with TNBC. Methods Patients with TNBC who were treated at the University Medical Centre Maribor between January 2010 and December 2017 were studied. Clinical and pathological data were analyzed using multivariate analysis and non-parametric tests. Subgroup analysis was performed to examine additional factors that affect 5-year overall survival (OS) and recurrence-free survival. Results Multivariate analysis showed that tumor size and the lymph node ratio (LNR) were significant risks in our population. Better discrimination of patients at risk of a shorter recurrence-free survival and OS was achieved by using the LNR. Only lymphovascular invasion was significant for predicting 5-year OS. Conclusion For risk-based decision-making systems, the LNR is useful for discriminating between high- and low-risk patients with TNBC.

We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding histone cluster 1, H2am, HIST1H2AM, when comparing the tumor cells of patients with triple negative breast cancer to normal mammary ductal cells (2). HIST1H2AM was also differentially expressed in bulk tumor in human breast cancer (3). HIST1H2AM mRNA was present at significantly increased quantities in TNBC tumor cells relative to normal mammary ductal cells. Analysis of human survival data revealed that expression of HIST1H2AM in primary tumors of the breast was correlated with recurrence-free survival in patients with normal-like type cancer, while within triple negative breast cancer, primary tumor expression of HIST1H2AM was correlated with recurrence-free survival in patients with basal-like 1 subtype disease. HIST1H2AM may be of relevance to initiation, maintenance or progression of triple negative breast cancers.
