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.

e12014 Background: Oncotype-DX Assay is a 21-gene based recurrence score (RS) that helps stratify breast cancer patients based on their risk of recurrence. It is often used to help identify patients that may benefit from adjuvant chemotherapy (AC). Prior to the TAILORx Trial results, there were no guidelines for AC in patients with an intermediate score (18-30). Management of these patients was often at the clinical judgement of the provider. We sought to determine predictors of AC among these patients, and measure treatment effect on survival. Methods: We queried the Surveillance, Epidemiology, and End-Results database for breast cancer patients newly diagnosed between 2010-2015. We included patients with T1-T3, hormone receptor positive, HER2-negative, and lymph node-negative breast cancer with an intermediate RS. Male patients, those younger than 40 years, tumors 5 mm or less, and incomplete records were excluded. Univariate and multivariate analysis was performed to derive independent predictors of AC. Cox Proportional-Hazards Model was done to examine the effect of AC on survival. Results: We included 14,710 patients of whom 4,508 (30.6%) received AC. Patients that received AC were younger (55.4 years [8.8] vs 60.0 [9.7], p < 0.001), grade III or higher (29.8% vs 16.4%, p < 0.001), and had a higher RS (23.9 [3.6] vs 21.5 [3.1], p < 0.001). Higher T stage was associated with a higher rate of patients receiving AC (p < 0.001). Marital status was also associated with AC; a higher proportion of patients who received AC were married (67.9% vs 64.4%, p < 0.001). There was no significant association between race/ethnicity or insurance type with AC. Multivariate analysis showed that RS (OR: 1.24 [1.23-1.26], p < 0.001), T stage (OR: 1.67 [1.21-2.30], p < 0.001), and a grade III tumor (OR: 1.85 [1.64-2.09], p < 0.001) were the strongest predictors of AC. The age decile 80-89 years (OR: 0.05 [0.02-0.10], p < 0.001) was the most negative predictor of AC. AC did not have an effect on 5 year overall survival (97.6% vs 96.0%, p = 0.28). Conclusions: Between 2010-2015, our study shows 30.6% of breast cancers patients with an intermediate Oncotype-DX score were given AC. The decision to treat was largely based on tumor size, grade and age. AC had no effect on overall survival.

Abstract Background Immediate breast reconstruction with tissue expander in breast cancer patients who were expected to receive adjuvant therapy, such as chemotherapy or radiotherapy, has been a topic of debate. Postoperative complications from tissue expander procedures can delay the timing of adjuvant treatment and subsequently increase the probability of recurrence. The purpose of this study was to identify the impact of chemotherapy and radiotherapy on postoperative complications in patients who underwent immediate reconstruction (IR) using tissue expander. Methods We conducted a retrospective study of 1081 breast cancer patients who underwent mastectomy and IR using tissue expander insertion between 2012 and 2017 in Samsung Medical Center. The patients were divided into two groups based on complications (complication group vs. no complication group). Complication group was regarded to have surgical removal or conservative treatment based on clinical findings such as infection, capsular contracture, seroma, hematoma, rupture, malposition, tissue viability, or cosmetic problem. The complication group had 59 patients (5.5%) and the no complication group had 1022 patients (94.5%). Results In univariate analysis, adjuvant radiotherapy and adjuvant chemotherapy were significantly associated with postoperative complications. In multivariate analysis, however, only higher pathologic N stage was significantly associated with postoperative complications (p < 0.001). Chemotherapy (p = 0.775) or radiotherapy (p = 0.825) were not risk factors for postoperative complications. Conclusions IR with tissue expander after mastectomy may be a treatment option even when the patients are expected to receive adjuvant chemotherapy or radiotherapy. These results will aid patients who are concerned about the complications of IR caused by chemotherapy or radiotherapy determine whether or not to have IR. Trial registration Patients were selected and registered retrospectively, and medical records were evaluated.

The Impact

Background Adjuvant chemotherapy for breast cancer is frequently accompanied by neutropenia requiring dose reduction or treatment delay that can potentially compromise therapeutic effectiveness. Recombinant granulocyte-colony stimulating factor (G-CSF) reduces the duration and severity of neutropenia. Methods Nineteen patients with newly diagnosed breast cancer receiving adjuvant systemic chemotherapy met criteria for dose reduction or treatment delay due to neutropenia. All were treated with G-CSF. The mean duration of G-CSF therapy was five days. Results An increase in mean absolute neutrophil count was seen in cycles with G-CSF. Chemotherapy treatment was delayed less often following the use of G-CSF. Conclusions Breast cancer patients receiving adjuvant chemotherapy who face treatment delays or dose reductions can continue on full-dose intensity therapy using supportive G-CSF. Prospective trials are needed to accurately measure the impact of G-CSF on dose intensity and long-term disease control.

AbstractWe hypothesized that a deep-learning algorithm using HE images might be capable of predicting the benefits of adjuvant chemotherapy in cancer patients. HE slides were retrospectively collected from 1343 de-identified breast cancer patients at the Samsung Medical Center and used to develop the Lunit SCOPE algorithm. Lunit SCOPE was trained to predict the recurrence using the 21-gene assay (Oncotype DX) and histological parameters. The risk prediction model predicted the Oncotype DX score > 25 and the recurrence survival of the prognosis validation cohort and TCGA cohorts. The most important predictive variable was the mitotic cells in the cancer epithelium. Of the 363 patients who did not receive adjuvant therapy, 104 predicted high risk had a significantly lower survival rate. The top-300 genes highly correlated with the predicted risk were enriched for cell cycle, nuclear division, and cell division. From the Oncotype DX genes, the predicted risk was positively correlated with proliferation-associated genes and negatively correlated with prognostic genes from the estrogen category. An integrative analysis using Lunit SCOPE predicted the risk of cancer recurrence and the early-stage hormone receptor-positive breast cancer patients who would benefit from adjuvant chemotherapy.
