32 Background: The Oncotype DX (ODX) multigene assay has been previously suggested to result in an overall reduction in the use of adjuvant chemotherapy and associated costs for women with early stage, estrogen receptor (ER)-positive breast cancer. However, the association between adoption of ODX and chemotherapy costs has only previously been considered in theoretical models and has not been examined using actual patient outcomes in real world clinical practice. Methods: Retrospective analysis of Surveillance, Epidemiology, and End Results (SEER) -Medicare data of the association between overall and chemotherapy-specific costs associated with adoption of ODX testing in patients diagnosed with invasive, non-metastatic, ER-positive breast cancer between 2005 and 2009. We limited our primary analysis to women ages 66 to75 to include women in which adjuvant chemotherapy would be most likely to be considered. Total Medicare payments were used to calculate direct costs in the year following diagnosis. NCCN guidelines were used to stratify patients on the basis of clinical and pathologic features into low ( < 1.0 cm), intermediate, and high risk (node positive) disease. Results: A total of 21,272 women met study criteria. Average costs in the year following diagnosis were $31,532 in the overall cohort, and was highest for women with NCCN high risk ($45,192) vs. intermediate ($28,642) or low ($23,662) risk disease. Chemotherapy costs followed similar trends ($4,819, $1,157, and $226 respectively). In multivariable analyses, ODX was associated with a relative decrease in chemotherapy costs among high risk women (RR 0.54, 0.37-0.77), but increased costs among low and intermediate risk women (RR1.36, 1.13-1.26 and RR 3.73, 2.13-56.54). Women with high risk disease had significantly lower absolute chemotherapy costs associated with receipt of ODX (-$2,298, -$3,049 to -$1,547; All P < 0.001). Conclusions: Receipt of ODX testing was associated with relative and absolute decreases in chemotherapy costs, but only in women with high NCCN risk disease. Further research is needed to disentangle correlative vs. causative association of ODX testing with patient outcomes and costs.

309 Background: In 2004, the Oncotype DX (ODX) multigene assay became available to help guide physicians in their decision to recommend adjuvant chemotherapy in patients with early stage estrogen receptor (ER) positive breast cancer. ODX utilization within a non-academic, nationally representative breast cancer population has not been previously examined. Methods: Retrospective analysis of Surveillance, Epidemiology, and End Results (SEER)-Medicare data of the association between ODX testing and receipt of chemotherapy in patients diagnosed with invasive, non-metastatic, ER-positive breast cancer between 2004 and 2007. Results: A total of 28,760 Medicare beneficiaries met study criteria. NCCN guidelines were used to stratify patients on the basis of clinical and pathologic features into low (<1 cm tumors, 24.4%), intermediate (≥ 1 cm tumors, 52.0%), and high (node positive, 23.7%) risk disease. In patients with low or intermediate risk disease, receipt of ODX was associated with increased chemotherapy utilization (13% vs. 1% and 19% vs. 8%, respectively; both P < 0.001), but not in high risk patients (30% vs. 39%, P= 0.34). Conclusions: Randomized trials have previously suggested the ability of ODX to decrease chemotherapy utilization. In this study, we observed increased chemotherapy utilization associated with receipt of ODX in patients with low and intermediate NCCN risk disease. Association between ODX and chemotherapy utilization in observational studies may be impacted by preferential administration of ODX testing to patients being considered for chemotherapy.

Abstract Background: The predictive value of adjuvant chemotherapy for early-stage hormone receptor-positive breast cancer has been only validated by a 21-gene expression assay. We hypothesized that deep-learning prediction from HE images, called Lunit-SCOPE, is a potential prognostic and predictive biomarker of adjuvant chemotherapy.Methods: We retrospectively collected HE slides from 1153 de-identified breast cancer patients at the Samsung Medical Center (SMC) in order to develop a deep-learning algorithm called Lunit-SCOPE. The histological parameters from 255 patients, deciphered by Lunit-SCOPE, were trained to predict the recurrence score (RS) using the 21-gene assay from Oncotype DX. We validated the model’s performance using the recurrence survival of 898 patients and The Cancer Genome Atlas (TCGA) cohort, and examined related biological functions through RNA sequence data.Results: The histologic parameter-based RS prediction model predicted the oncotype DX score (R2=0.96) and the recurrence survival analysis on the validation (p<0.01) and TCGA cohort (p<0.01), where the most important variables were the nuclear grade and the mitotic cells in the cancer epithelium. Of the 85 patients classified as the high-risk group, 72 patients who received adjuvant therapy had a significantly better survival (p<0.01). The functions of the top 300 highly correlated genes with a predicted RS were enriched for cell cycle, nuclear division and cell division. Of the 21-genes from the Oncotype DX, the predicted RS had positive correlations with the proliferation category genes and was negatively correlated with the prognostic genes in the estrogen category.Conclusion: An integrative analysis using Lunit-SCOPE predicts a high risk of recurrence and those who would benefit from adjuvant chemotherapy for early-stage hormone-positive breast cancer.

e12519 Background: The 21 gene assay Oncotype Dx Breast Recurrence Score (RS) is currently the standard of care to determine if adjuvant chemotherapy is needed in early stage node negative, hormone receptor positive, HER-2 negative breast cancer. In current American society of clinical oncology (ASCO) guidelines there is little or no benefit of adjuvant chemotherapy in patients older than 50 years whose tumors have Oncotype DX RS <26, and for patients 50 years or less whose tumors have Oncotype DX RS <16. We sought to evaluate the percentage of estrogen receptor (ER) expression as a surrogate measure of determining adjuvant chemotherapy by examining the relationship between ER expression and RS. Methods: We identified 301 patients from years 2015 to 2019 from our cancer registry with early stage hormone receptor positive breast cancer and had oncotype DX testing performed. We divided patients into three groups: Group 1 (ERG1) with ER <10%; Group 2 (ERG2) with ER 10-49%; and Group 3 (ERG3) with ER equal or >50%. We also collected information on tumor size (cm), tumor grade, Nottingham score, and ki-67 percentage. A sub-group analysis was performed for patients < 50 years age (n=30). We compared all continuous variables across ER groups using the Kruskal-Wallis rank test and individual between group comparisons using the Wilcoxon rank sum test. All statistical tests performed utilized a two-tailed p value of <0.05 with the Bonferroni correction for multiple comparisons. Results: Among 301 patients with early stage hormone receptor positive breast cancer, 89.1% were ductal, 7.9% lobular, and 2.9% mixed histology. Median age was 68, 58 and 66 for ERG1, ERG2, and ERG3, respectively (p = 0.41). Median RS was 36 (ERG1), 23 (ERG2), and 16 (ERG3) (p = 0.78 for ERG1 vs. ERG2; p = 0.01 for ERG1 vs. ERG3). As expected, tumor grade, tumor size, and Nottingham score decreased significantly from ERG1 to ERG3. For patients <50 years, median age was 44, 46 and 45 for ERG1, ERG2, and ERG3, respectively (p = 0.75). Median RS was 10 (ERG1), 24 (ERG2) and 18 (ERG3) (p = 0.04 for ERG1 vs. ERG2; p = 0.17 for ERG1 vs. ERG3). Conclusions: We found a significant association between estrogen receptor levels and Oncotype Dx recurrence score (RS) in patients with early stage hormone receptor positive breast cancer patients. Further studies are needed to determine the predictive ability of hormone receptor levels on the outcomes of patients treated for early stage hormone receptor positive breast cancer.

e12520 Background: Oncotype Dx (ODX) is a commercial diagnostic test primarily used to predict the likely benefit from chemotherapy in ER+, HER2-, and node negative breast cancer. The prognostic value (recurrence risk) has also been demonstrated to apply to early stage lymph node positive (LN+) disease in a number of retrospective and prospective studies. The ongoing RxPONDER trial aims to clarify the predictive value of RS in LN+ population. In light of the initial results, we analyzed the practice patterns and outcomes for HR+/Her2 -/node positive breast cancer patients receiving ODX testing in the years from 2010-2017 with RS 14-25 in a retrospective observational study of the NCDB. Methods: Women with HR+/Her2 -/node positive breast cancer receiving ODX testing from 2010-2017 were identified in the NCDB using TAILORx and RxPONDER patients’ inclusion criteria: ages 18-75, 6-50mm invasive tumors, N1, M0, ER+/HER2 -. The impact of ODX results in the high-intermediate range (14-25) and other clinico-pathologic variables on the receipt of chemotherapy were compared. Additionally, we examined the impact of chemotherapy on overall survival (OS). Frequencies, Kaplain-Meier analysis, and changepoint analysis using the Contal and O’Quigley method were utilized. Results: There were 109,652 T1-2 and N1 patients of whom 32,506 (29.6%) received ODX testing. 13,461 (41.4%%) women had scores in the high-intermediate (14-25) range. The majority tended to have only 1 LN involved (1LN: 77.2%, 2LNs: 17.5%, 3LNs: 5.3%), had a mean age of 57.8y, were Caucasian (86.4%), and were preferentially tested at academic or comprehensive community cancer programs (79.2%). 6,610 (49.3%) patients were recommended chemotherapy, the median ODX score for all women who were recommended chemotherapy was 20 compared to 17 for those whom chemotherapy was not recommended. 5,068 (76.7%) women had documentation of receiving chemotherapy which correlated with improved OS regardless of age. Conclusions: In the group of women with HR+/Her2 -/node positive breast cancer, clinicians appear to utilize ODX testing in less than one-third of patients, possibly finding RS to be most useful in guiding adjuvant therapy recommendations when only 1LN is involved. Both the recommendation and receipt of chemotherapy correlated linearly with increasing RS, as expected based on the current NCCN guideline recommendations. We identified an OS benefit when chemotherapy was administered, regardless of patient age. Long-term follow-up in the RxPONDER trial will likely continue to clarify the predictive value of RS < 25 in the ER+/HER2-/node positive breast cancer population.
