Abstract Background Triple-negative breast cancer (TNBC) is characterized by poor prognosis and lack of targeted therapies and biomarkers to guide decisions on adjuvant chemotherapy. Parathyroid hormone-related protein (PTHrP) is frequently overexpressed in breast cancer and involved in proliferation and metastasis, two hallmarks of poor prognosis for node-negative breast cancer. We investigated the prognostic value of PTHrP with respect to organ-specific metastasis and nodal status in TNBC. Methods We assessed PTHrP expression using immunohistochemistry in a clinically annotated tissue microarray for a population-based study of 314 patients newly diagnosed with TNBC, then analyzed its correlation to progression and survival using Kaplan-Meier and Cox regression analyses. The Cancer Genome Atlas (TCGA) validation analysis was performed through Bioconductor. All statistical tests were two-sided. Results PTHrP overexpression (160 of 290 scorable cases, 55.2%) was statistically significantly associated in univariate analysis with decreased overall survival (OS) in our cohort (P = .0055) and The Cancer Genome Atlas (P = .0018) and decreased central nervous system (CNS)-progression-free survival (P = .0029). In multivariate analysis, PTHrP was a statistically significant independent prognostic factor for CNS-progression-free survival in TNBC (hazard ratio [HR] = 5.014, 95% confidence interval [CI] = 1.421 to 17.692, P = .0122) and for OS selectively in node-negative TNBC (HR = 2.423, 95% CI = 1.129 to 5.197, P = .0231). Strikingly, PTHrP emerged as the only statistically significant prognostic factor (HR = 2.576, 95% CI = 1.019 to 6.513, P = .0456) for OS of low-clinical risk node-negative patients who did not receive adjuvant chemotherapy. Conclusions PTHrP is a novel independent prognostic factor for CNS metastasis and adjuvant chemotherapy selection of low-clinical risk node-negative TNBC. Its predictive value needs to be prospectively assessed in clinical trials.

Abstract Purpose: National Comprehensive Cancer Network guidelines recommend delivery of adjuvant chemotherapy in node-negative triple negative breast cancer (TNBC) if the tumor is > 1 cm and consideration of adjuvant chemotherapy for T1b but not T1a disease. These recommendations are based upon sparse data regarding the role of adjuvant chemotherapy in T1a and T1b node-negative TNBC. Our objective was to clarify the benefits of chemotherapy for patients with T1N0 TNBC, stratified by tumor size.Methods: We performed a retrospective analysis of survival outcomes in an IRB-approved prospectively-maintained database of TNBC patients treated at two academic institutions in the United States from 1999-2018. Primary tumor size, histology, and nodal status were based upon definitive surgical pathology. Mean follow-up was 5.3 years.Results: 756 TNBC cases were analyzed; 258 T1N0 TNBC patients were identified. Adjuvant chemotherapy was delivered to 30.5% of T1a, 64.7% T1b, and 83.9% T1c (p < 0.0001). Factors associated with delivery of adjuvant chemotherapy were age, histology, high-grade disease, and postoperative adjuvant radiation therapy. At a mean follow-up of 5.3 years, increase in overall survival was associated with use of chemotherapy in patients with T1c disease (93.2% v. 75.2% p = 0.008) but not in those with T1a (100% v. 100% p = 0.3778) or T1b (100% v. 95.8% p = 0.2362) disease.Conclusion: Our data support current guidelines indicating benefit from adjuvant chemotherapy in node-negative TNBC associated with T1c tumors but excellent outcomes were observed in cases of T1a and T1b disease, regardless of whether adjuvant chemotherapy was delivered.

e12021 Background: There is currently lack of adequate data to support for or against the role of adjuvant chemotherapy for small( < = 5mm) hormone negative and node negative breast cancer. We did a retrospective analysis from National Cancer Database (NCDB) to assess the effect of adjuvant chemotherapy in HER2 positive/ Hormone receptor negative (HER+HR-) and triple negative breast cancer. Methods: Data was analyzed from approximately nine thousand women registered in the (NCDB) who were diagnosed with triple negative and HER+ HR-small ( < = 5mm) and node negative breast cancer between 2010 and 2014 and had follow-up to the end of 2015. The primary predictor variable was the receipt of chemotherapy, and outcome variable was overall survival. Additional variables addressed and adjusted included age, race, Charlson Comorbidity Index and grade of cancer. Results: Approximately 59% patients received adjuvant chemotherapy. The five year overall survival in women with triple negative for breast cancer who received chemotherapy was 79% , compared to 87% , for those who did not receive chemotherapy(p < 0.00001). The five year overall survival in women with Her2+HR- for breast cancer who received chemotherapy was 68% , compared to 84% , for those who did not receive chemotherapy(p < 0.00001).In multivariate analysis, after adjusting for secondary predictor variables, avoidance of adjuvant chemotherapy was associated with 59.5% reduction in risk of death. Conclusions: Our analysis suggests that there are no role for adjuvant chemo in small breast cancers that are Her+ HR- and triple negative. The receipt of adjuvant chemotherapy lead to decrease in overall survival.
