e13023 Background: Targeted cancer therapy has been posited to revolutionize treatment paradigms in oncology. There are, a paucity of data regarding the use of NGS in breast cancer (BC). Herein we report our experience with NGS in a consecutive series of BC patients. Methods: Using an IRB approved protocol, we retrospectively identified patients with BC treated at the Sylvester Comprehensive Cancer Center (UMMSOM) who underwent NGS. Data were collected on demographics, tumor characteristics, genomic mutation profiles, and subsequent response to targeted therapy after 3 months. Results: Between January 2013 and April 2016, 101 BC patients underwent NGS. The mean age at diagnosis was 49. Ninety-one percent were stage IV, 6% were stage III, 2% were stage II, and 1% were stage I. Fifty percent had estrogen receptor (ER)+, HER2- tumors, 31% had triple-negative tumors, 13% had HER2+, ER+ tumors, and 6% had HER2+, ER- tumors. Ninety-six percent had at least one mutation, of which 78% had a targetable mutation. Sixteen patients received targeted therapy (TT). The average time between NGS and TT was 5 months ranging 0-22 months, during which seven patients received other systemic therapy. The most common reasons for not receiving TT were no actionable mutations (24%), not meeting criteria for an available clinical trial (14%), stable disease (SD) (13% ), lost to follow up (11%), physician decision (11%). Of the 16 patients who received TT, 7 patients had progression of disease, 3 died before response could be evaluated and presumably had no benefit, 2 discontinued TT due to side effects, 1 had SD, 1 had a partial response, and 2 were too early to be assessed. Conclusions: The majority of BC patients in our series had actionable mutations. However, TT was not offered to a significant number of patients for a multiplicity of reasons and the clinical benefit in those patients treated according to NGS findings was dismal. While NGS is surely a promising technology that should be utilized in combination with molecular tumor board, a host of reasons limit its usefulness at this time and its expense may well not justify its use outside of clinical trials.

118 Background: Guidelines for treating inflammatory breast cancer (IBC) using trimodality (chemotherapy, surgery and radiation) therapy (TT) remain largely unchanged since 2000. However, many such patients did not receive TT. It is unknown how patient-level (PL) and facility-level (FL) factors contribute to TT utilization. Methods: Using the National Cancer Data Base (NCDB), patients who underwent surgical treatment of locoregional IBC from 2003-2011 were identified. We correlated patient, tumor, and treatment data with TT. An observed to expected (O/E) ratio of number of patients treated with TT was calculated for each hospital by adjusting for PL factors. Hierarchical mixed effects models were used to assess the proportion of variation in the use of TT attributable to PL and FL factors, respectively. Results: Among 5,537 patients who met the study criteria, the use of TT fluctuated annually (67.3%-75.7%) and was less likely for patients who were over 70, had a lower income or had an N0 tumor (all p < 0.05). By insurance type, TT use was lowest among Medicare patients. Of the 542 hospitals examined, 55 (10.1%) and 24 (4.4%) were identified as significantly low and high outliers for the use of TT (p < 0.05), respectively. While comprehensive cancer centers represented the majority of high outliers, the TT use by facility type overall was not significantly different demonstrating variability within comprehensive cancer center practice. The percentage of the total variance in the use of TT attributable to facility (11%) was almost triple the variance attributable to the measured PL factors (3.4%). Conclusions: The use of standard of care TT varied widely across facilities with some high volume centers clearly underutilizing TT. To improve clinical outcomes for this rare and aggressive malignancy, it is critical to identify facility level factors impacting the use of TT to ensure the guideline adherence of IBC treatment.

89 Background: In 2006, Tahoe Forest Hospital District—a 25-bed hospital in Truckee, CA, a mountain resort community one hour from regional and two hours from academic cancer services—designed and implemented an oncology program utilizing effective telecommunications with a committed academic partner, the UC Davis Comprehensive Cancer Center in Sacramento. Methods: The UC Davis Cancer Care Network was established with four remote cancer programs, enabling participation in daily virtual tumor boards, clinical trial enrollment, and quality assurance assistance. (Richard J. Bold, et. al., Virtual tumor boards: community-university collaboration to improve quality of care. Community Oncol 10(11):310-315, November 2013.; Laurence J. Heifetz, MD, et. al., A Model for Rural Oncology. J Oncol Pract, 7:168-171, May 2011.). An increasing number of patients were observed to in-migrate to Truckee from even more remote rural areas in the mountains. In 2013, the now Gene Upshaw Memorial Tahoe Forest Cancer Center developed four remote telemedicine clinics to allow even more physically distant patients the capacity to be followed locally. Results: Since we opened the remote telemedicine clinics, our Sullivan-Luallin patient satisfaction scores have averaged 4.82/5.00 for “overall satisfaction with the practice” and 4.90/5.00 for “recommending your provider to others”; our in-migration rate of patients from outside our primary catchment area increased from 43% to 52%: and clinical trial accrual rate averaged 10%. Conclusions: Reducing cancer health disparities is an ASCO mission. (cover, ASCO Connection, July 2014; Laurence J. Heifetz, MD. Country Docs with City Technology Can Address Rural Cancer Care Disparities. Oncol, 29(9):641-644, September 2015.). We believe this synaptic knowledge network effectively addresses that mission for rural communities. This model can be scaled in many configurations to address the inherent degradation of quality care as a function of physical distance to an academic center that rural doctors and patients deal with on a daily basis. The key is to insist on a cultural shift – Do something smart at lunch every day. Attend a virtual tumor board.

1071 Background: Patients (pts) with Human Immunodeficiency Virus (HIV) are living longer and non-AIDS defining malignancies have been increasingly reported in these patients. Methods: Retrospective review identified 47 pts with breast cancer (BC) and HIV who were seen at the University of Miami Sylvester Comprehensive Cancer Center/Jackson Memorial Hospital between January 1999 and June 2011. Results: Pt characteristics: 46 female, 1 male, mean age 46 years (range 31-65). Race: African American 79%, Caucasian 21%. Ethnic: Hispanics 14%, non-Hispanics 86%. Premenopausal 68% postmenopausal 32%. Tumor characteristics: Stage: Tis 4%, Stage I: 6 % , Stage II: 38%, Stage III: 38%, Stage IV: 9%. ER positive (50%) her-2 positive (15%), Triple negative (21%). HIV characteristics: 36 pts with HIV before or concurrent with the diagnosis of BC. 6 pts diagnosed with HIV within 1 year of BC diagnosis. HIV dx date unavailable in 5 pts. 27% had AIDS. CD4 counts (in cells/µL)were: > 500 (23%); 201-500 (37%), 51 – 200 (20%) < 50 (20%). 15 pts were diagnosed with BC in preHAART era. Of those dx with BC after 1996, 60% were on HAART. BC treatment: 43 pts had localized disease. 32 underwent modified radical mastectomy, 8 breast conservation and 3 pts refused surgery. 26 pts received curative or palliative chemotherapy. Complications of BC treatment: serious side effects were reported in 11 (42%) including neutropenic fever/sepsis (10 pts), ARDS (1 pt). Zoster infection was reported in 12% of the pts. 3 patients developed rapidly progressive and fatal AIDS within 6 months of completion of chemotherapy. Survival: See Table. Conclusions: BC in patients with HIV infection spans the spectrum of BC presentations. Hormonal therapy, surgery and radiation therapy were well tolerated. Infectious complications were common in patients treated with chemotherapy and routine use of growth factors and prophylactic acyclovir should be considered. [Table: see text]

BackgroundNeoadjuvant chemotherapy (NAC) with taxanes is the standard of care in triple negative breast cancer (TNBC). Intratumoral prevalence of CD8+ cytotoxic T-lymphocytes (CTLs) is associated with an improvement in relapse-free survival (RFS) and overall survival (OS), while regulatory T-cells (Treg) and myeloid derived suppressor cells (MDSC) are associated with poor survival. Higher ratio of CTL/Treg is associated with higher probability of obtaining pathological complete response (pCR), a surrogate marker for RFS. Intratumoral production of CCL5, CXCL9, CXCL10 and CXCL11 is critical for local infiltration with CTLs, while CCL22 is responsible for Treg attraction. Previous studies have shown that CXCL9 expression in the pre-treatment breast tissue is associated with a three-fold higher rate of achieving pCR. Our preclinical data show that Chemokine modulating (CKM) regimen, combining rintatolimod (TLR3 agonist), interferon (IFN)-α2b, and celecoxib (COX-2 inhibitor) increases CTL-attracting, and decreases MDSC-, Treg-favoring chemokines, increasing CTL/Treg ratio in tumor microenvironment, with preferential tumor tissue activation than adjacent healthy tissues. We hypothesize that the combination of CKM with paclitaxel will result in infiltration of TNBC with CTLs, and along with doxorubicin/cyclophosphamide (AC), result in higher pCR, translating into improved RFS and OS.MethodsIn this phase I study NCT04081389, eligibility includes age ≥18 years, confirmed resectable TNBC, radiographically measurable disease ≥1 cm, ECOG PS ≤ 2, adequate organ and marrow function. Patients with autoimmune disease, serious mood disorders, invasive carcinoma within 3 years, history of peptic ulcers or hypersensitivity to NSAIDs will be excluded. We plan to treat three patients with early stage TNBC with paclitaxel 80 mg/m2 IV weekly for 12 weeks, rintatolimod 200 mg IV, celecoxib 200 mg oral twice daily, and accelerated titration of IFN-α2b at doses 0, 5, or 10 million units (MU)/m2 [Dose Levels (DL) 1, 2 and 3 respectively] on days 1–3 (no intra-patient dose escalation) in weeks 1–3. Dose-limiting toxicity (DLT) is defined as grade 3 or higher toxicities within the first 3 weeks. Any DLT will mandate recruitment per the 3+3 model. If no DLT, three patients will be enrolled at DL 4 at 20 MU/m2 IFN- α2b. This will be followed by standard dose-dense AC, and then surgery. The primary endpoint is safety and tolerability of combination and to identify the appropriate DL of CKM and paclitaxel for extended efficacy study. The secondary endpoints include investigation of efficacy (pCR and breast MRI response), along with RFS and OS. Intratumoral biomarkers will be analyzed in an exploratory manner.ResultsN/AConclusionsN/ATrial RegistrationNCT04081389Ethics ApprovalThe study was approved by Roswell Park Comprehensive Cancer Center Institution’s Ethics Board, approval number I-73718.

6501 Background: Effective cancer screening leads to a substantial increase in the detection of earlier stages of cancer, while decreasing the incidence of later stage cancer diagnoses. Timely screening programs are critical in reducing cancer-related mortality in both breast and colorectal cancer by detecting tumors at an early, curable stage. The COVID-19 pandemic resulted in the postponement or cancellation of many screening procedures, due to both patient fears of exposures within the healthcare system as well as the cancellation of some elective procedures. We sought to identify how the COVID-19 pandemic has impacted the incidence of early and late stage breast and colorectal cancer diagnoses at our institution. Methods: We examined staging for all patients presenting to UCSD at first presentation for a new diagnosis of malignancy or second opinion in 2019 and 2020. Treating clinicians determined the stage at presentation for all patients using an AJCC staging module (8th edition) in the electronic medical record (Epic). We compared stage distribution at presentation in 2019 vs 2020, both for cancers overall and for colorectal and breast cancer, because these cancers are frequently detected by screening. Results: Total numbers of new patient visits for malignancy were similar in 2019 and 2020 (1894 vs 1915 pts), and stage distribution for all cancer patients was similar (stage I 32% in 2019 vs 29% in 2020; stage IV 26% in both 2019 and 2020). For patients with breast cancer, we saw a lower number of patients presenting with stage I disease (64% in 2019 vs 51% in 2020) and a higher number presenting with stage IV (2% vs 6%). Similar findings were seen in colorectal cancer (stage I: 22% vs 16%; stage IV: 6% vs 18%). Conclusions: Since the COVID-19 pandemic, there has been an increase in incidence of late stage presentation of colorectal and breast cancer, corresponding with a decrease in early stage presentation of these cancers at our institution. Cancer screening is integral to cancer prevention and control, specifically in colorectal and breast cancers which are often detected by screening, and the disruption of screening services has had a significant impact on our patients. We plan to continue following these numbers closely, and will present data from the first half of 2021 as it becomes available.

e13056 Background: Invasive lobular carcinoma (ILC) accounts for only 10-15% of all invasive breast cancers but has distinct clinicopathologic characteristics and genomic profiles. In particular, metastatic lobular cancers (mILC) have unique sites of metastasis and it is unclear if the response to initial endocrine therapy differs from metastatic ductal cancers (mIDC). Therefore we have undertaken a single-institution, retrospective analysis to compare overall outcomes and response to initial endocrine therapy (ET) in patients (pts) with metastatic ILC and IDC. Methods: An IRB approved retrospective review of medical records was conducted evaluating pts treated for metastatic IDC and ILC at The Ohio State University Comprehensive Cancer Center from January 1, 2004 to December 31, 2014. Pts diagnosed with mIDC were matched on age, year of diagnosis, estrogen receptor/progesterone receptor and HER2 status and site of metastasis 2:1 to patients diagnosed with mILC. Overall survival (OS) was defined as the time from metastasis to death or last known follow-up. Progression-free survival (PFS) was defined as time from metastasis to progression on first-line ET. Time to chemotherapy (TTC) was defined as time from starting ET for metastasis to initiation of chemotherapy. Kaplan Meier (KM) methods were used to calculate median OS, PFS and TTC. Results: A total of one hundred sixty one pts with metastatic breast cancer were included in this analysis. The demographic features between the two groups were well balanced and included in the table below. The median OS was 2.6 yrs (95% CI: 1.55, 3.22) for mILC and 2.2 yrs (95% CI: 1.95, 2.62) for mIDC. A subset of 111 patients who started on endocrine therapy were used in the PFS and TTC analyses. The median PFS following first-line ET was 2.2 yrs (95% CI: 0.1.0, 2.7) for mILC and 1.4 yrs (95% CI: 0.91, 1.90) for mIDC. Median TTC was 2.1 yrs (95% CI: 1.71, 4.92) for mILC and 2.4 yrs (95% CI: 1.90, 4.77) for mIDC. There was no statistically significant difference in outcomes between the two groups. Conclusions: Outcomes in patients with ILC and IDC have been varied, with several studies reporting that patients with ILC have worse outcomes and response to chemotherapy. Our retrospective study examining outcomes in mILC in comparison with mIDC showed no difference in OS. Given the concern of resistance to conventional therapies in patients with lobular cancers, it is reassuring to see that the median PFS on first line ET and TTC was similar to metastatic ductal cancers.[Table: see text]

Purpose Several models have been developed to predict nonsentinel lymph node (non-SN) status in patients with breast cancer with sentinel lymph node (SN) metastasis. The purpose of our investigation was to compare available models in a prospective, multicenter study. Patients and Methods In a cohort of 561 positive-SN patients who underwent axillary lymph node dissection, we evaluated the areas under the receiver operating characteristic curves (AUCs), calibration, rates of false negatives (FN), and number of patients in the group at low risk for non-SN calculated from nine models. We also evaluated these parameters in the subgroup of patients with micrometastasis or isolated tumor cells (ITC) in the SN. Results At least one non-SN was metastatic in 147 patients (26.2%). Only two of nine models had an AUC greater than 0.75. Three models were well calibrated. Two models yielded an FN rate less than 5%. Three models were able to assign more than a third of patients in the low-risk group. Overall, the Memorial Sloan-Kettering Cancer Center nomogram and Tenon score outperform other methods for all patients, including the subgroup of patients with only SN micrometastases or ITC. Conclusion Our study suggests that all models do not perform equally, especially for the subgroup of patients with only micrometastasis or ITC in the SN. We point out available evaluation methods to assess their performance and provide guidance for clinical practice.

Breast cancer survival rates are lower in African Americans (AAs) than in Caucasians, owing in part to a higher prevalence of obesity in the former, which increases the risk of recurrence and mortality. The Women’s Intervention Nutrition Study (WINS) found that Caucasian women who followed a low-fat eating plan experienced a lower rate of cancer recurrence than women who maintained their usual diets. The purpose of this study was to test the feasibility of a WINS plan tailored to the cultural needs of AA breast cancer survivors. This feasibility pilot study was conducted at a university National Cancer Institute-designated comprehensive cancer center outpatient clinic with AA breast cancer survivors. The culturally specific WINS (WINS-c) plan included eight individual counseling sessions, five educational group meetings, and follow-up telephone calls over a 1-year period. Outcome measures included dietary fat, triglyceride, insulin and glucose levels, and fruit and vegetable intake. Participants ( n = 8) had a mean age of 61.1 years (standard error of the mean (SEM) 3.1 years) and a mean BMI of 32 kg/m2 (SEM 4.25 kg/m)2. Baseline daily fat consumption decreased from 64.6 g (range 36.8–119.6g) to 44.0 g (21.6–73.4g) at 52 weeks ( p = 0.07). Mean daily consumption of fruits and vegetables increased by 36% and 15%, respectively. Mean triglyceride levels decreased at 12 months ( p < 0.05). Sustained hyperinsulinemia was noted in most participants, including those without diabetes. Mean calcium and vitamin D consumption decreased over the 1-year study period. In AA breast cancer survivors, the WINS-c program resulted in a trend toward reduced fat consumption and may represent a sustainable approach in this population for improvement of diet quality after breast cancer.
