Abstract
Chromosome region maintenance protein 1 (CRM1) mediates protein export from the nucleus and is a new target for anticancer therapeutics. Broader application of KPT-330 (selinexor), a first-in-class CRM1 inhibitor recently approved for relapsed multiple myeloma and diffuse large B-cell lymphoma, have been limited by substantial toxicity. We discovered that salicylates markedly enhance the antitumor activity of CRM1 inhibitors by extending the mechanisms of action beyond CRM1 inhibition. Using salicylates in combination enables targeting of a range of blood cancers with a much lower dose of selinexor, thereby potentially mitigating prohibitive clinical adverse effects. Choline salicylate (CS) with low-dose KPT-330 (K+CS) had potent, broad activity across high-risk hematological malignancies and solid-organ cancers ex vivo and in vivo. The K+CS combination was not toxic to nonmalignant cells as compared with malignant cells and was safe without inducing toxicity to normal organs in mice. Mechanistically, compared with KPT-330 alone, K+CS suppresses the expression of CRM1, Rad51, and thymidylate synthase proteins, leading to more efficient inhibition of CRM1-mediated nuclear export, impairment of DNA-damage repair, reduced pyrimidine synthesis, cell-cycle arrest in S-phase, and cell apoptosis. Moreover, the addition of poly (ADP-ribose) polymerase inhibitors further potentiates the K+CS antitumor effect. K+CS represents a new class of therapy for multiple types of blood cancers and will stimulate future investigations to exploit DNA-damage repair and nucleocytoplasmic transport for cancer therapy in general.

Abstract
While historically breast cancer has been treated with primary surgery followed by adjuvant therapy, the delivery of systemic therapy in the neoadjuvant setting has become increasingly common, especially for triple-negative and HER2-positive breast cancer. The initial motivations for pursuing neoadjuvant chemotherapy (NAC) were decreasing the tumor burden in the breast and axilla to enable de-escalation of surgery, and use the strategy to advance drug development. While these remain of interest, recent trials have additionally demonstrated survival advantages from escalation of systemic treatment in patients with residual disease, and new studies are testing de-escalation of systemic therapy based on pathologic response. Thus, response information to NAC has become pivotal to guide adjuvant treatment recommendations, and has resulted in NAC being the preferred approach for most HER2-positive and triple-negative breast cancers. Herein, we review select landmark trials that have paved the way for the use of chemotherapy in the neoadjuvant setting for breast cancer.

Abstract
BACKGROUND Tumor genomic prognostic assays estimate 10-year local recurrence risk in ductal carcinoma in situ (DCIS) and can guide treatment decisions. This study aimed to evaluate which DCIS patients treated with breast-conserving surgery (BCS) underwent DCIS score genomic testing and the influence of the results on adjuvant treatment recommendations. METHODS The study identified patients from the National Cancer Database (NCDB) who had DCIS treated with BCS from 2010 to 2016. RESULTS Of 141,047 patients, 4255 (3%) had a DCIS score assessed, 0.3% in 2010 increasing to 5.8% in 2016 (p < 0.001). The patients most likely to undergo DCIS score assessment had more favorable tumor features in the multivariable analysis. The DCIS score result was documented for 91.4% of the tested patients (n = 3888): 70.5% of the low-risk, 14.9% of the intermediate-risk, and 14.6% of the high-risk patients. The patients with low-risk scores were less likely to have radiation than those with intermediate- or high-risk scores among the patients with either ER + (35.0% vs 71.0% or 81.1%) or ER- disease (48.1% vs 77.0% or 85.5%) (each p ≤ 0.001). The patients who had ER + disease with high- and intermediate-risk scores were most commonly treated with both radiation and hormone therapy (HT) (57.1% and 52.2%), whereas the most common treatment for those with a low-risk DCIS score was HT alone without radiation (37.1%). Comparison of genomic testing with clinicopathologic features showed an independent influence of genomic testing on treatment. CONCLUSIONS Use of the DCIS score increased over time, predominantly for favorable DCIS. Patients with a low-risk score were significantly less likely to receive radiation, supporting an impact of the DCIS score on treatment de-escalation.

Abstract
BACKGROUND Diagnoses of multiple ipsilateral breast cancer (MIBC) are increasing. Historically, the primary treatment for MIBC has been mastectomy due to concerns about in-breast recurrence risk and poor cosmetic outcome. The Alliance Z11102 study prospectively assessed cosmetic outcomes in women with MIBC treated with breast-conserving therapy (BCT). PATIENTS AND METHODS Z11102 was a multicenter trial enrolling women with two or three separate sites of biopsy-proven malignancy separated by ≥ 2 cm within the same breast. Cosmetic outcome was a planned secondary endpoint. Data were collected with a four-point cosmesis survey (1 = excellent, 4 = poor) and the BREAST-Q (scored 0-100). All patients undergoing successful breast-conserving therapy were treated with whole-breast radiation. Associations were assessed with Chi square or Fisher's exact tests as appropriate. RESULTS Cosmetic outcome data for 216 eligible women who completed therapy are included in this analysis. Of the 136 patients who completed the survey 2 years postoperatively, 70.6% (N = 96) felt the result was good or excellent, while 3.7% (N = 5) felt the result was poor. We found no significant differences in patient-reported cosmetic outcomes when stratifying by patient age, number of lesions (two or three), number of incisions, number of lumpectomies, or size of largest area of disease. Mean satisfaction score on the BREAST-Q was 77.2 at 6 months following whole-breast radiation and 73.7 at 3 years following surgery. CONCLUSIONS BCT performed for MIBC results in good or excellent cosmesis for the majority of women. From a cosmetic perspective, BCT is a valid surgical approach to women with MIBC.

Abstract
Background: We developed a novel analytic tool for colorectal deep organ/space surgical site infections (C-OSI) prediction utilizing both institutional and extra-institutional American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) data. Methods: Elective colorectal resections (2006-2014) were included. The primary end point was C-OSI rate. A Bayesian-Probit regression model with multiple imputation (BPMI) via Dirichlet process handled missing data. The baseline model for comparison was a multivariable logistic regression model (generalized linear model; GLM) with indicator parameters for missing data and stepwise variable selection. Out-of-sample performance was evaluated with receiver operating characteristic (ROC) analysis of 10-fold cross-validated samples. Results: Among 2,376 resections, C-OSI rate was 4.6% (n = 108). The BPMI model identified (n = 57; 56% sensitivity) of these patients, when set at a threshold leading to 80% specificity (approximately a 20% false alarm rate). The BPMI model produced an area under the curve (AUC) = 0.78 via 10-fold cross- validation demonstrating high predictive accuracy. In contrast, the traditional GLM approach produced an AUC = 0.71 and a corresponding sensitivity of 0.47 at 80% specificity, both of which were statstically significant differences. In addition, when the model was built utilizing extra-institutional data via inclusion of all (non-Mayo Clinic) patients in ACS-NSQIP, C-OSI prediction was less accurate with AUC = 0.74 and sensitivity of 0.47 (i.e., a 19% relative performance decrease) when applied to patients at our institution. Conclusions: Although the statistical methodology associated with the BPMI model provides advantages over conventional handling of missing data, the tool should be built with data specific to the individual institution to optimize performance.

Abstract
Importance Pathologic complete response (pCR) is a known prognostic biomarker for long-term outcomes. The I-SPY2 trial evaluated if the strength of this clinical association persists in the context of a phase 2 neoadjuvant platform trial. Objective To evaluate the association of pCR with event-free survival (EFS) and pCR with distant recurrence-free survival (DRFS) in subpopulations of women with high-risk operable breast cancer treated with standard therapy or one of several novel agents. Design, Setting, and Participants Multicenter platform trial of women with operable clinical stage 2 or 3 breast cancer with no prior surgery or systemic therapy for breast cancer; primary tumors were 2.5 cm or larger. Women with tumors that were ERBB2 negative/hormone receptor (HR) positive with low 70-gene assay score were excluded. Participants were adaptively randomized to one of several different investigational regimens or control therapy within molecular subtypes from March 2010 through 2016. The analysis included participants with follow-up data available as of February 26, 2019. Interventions Standard-of-care neoadjuvant therapy consisting of taxane treatment with or without (as control) one of several investigational agents or combinations followed by doxorubicin and cyclophosphamide. Main Outcomes and Measures Pathologic complete response and 3-year EFS and DRFS. Results Of the 950 participants (median [range] age, 49 [23-77] years), 330 (34.7%) achieved pCR. Three-year EFS and DRFS for patients who achieved pCR were both 95%. Hazard ratios for pCR vs non-pCR were 0.19 for EFS (95% CI, 0.12-0.31) and 0.21 for DRFS (95% CI, 0.13-0.34) and were similar across molecular subtypes, varying from 0.14 to 0.18 for EFS and 0.10 to 0.20 for DRFS. Conclusions and Relevance The 3-year outcomes from the I-SPY2 trial show that, regardless of subtype and/or treatment regimen, including 9 novel therapeutic combinations, achieving pCR after neoadjuvant therapy implies approximately an 80% reduction in recurrence rate. The goal of the I-SPY2 trial is to rapidly identify investigational therapies that may improve pCR when validated in a phase 3 confirmatory trial. Whether pCR is a validated surrogate in the sense that a therapy that improves pCR rate can be assumed to also improve long-term outcome requires further study.

Abstract
BACKGROUND The maximum number of sentinel lymph nodes (SLN) to be resected to accurately stage the axilla in patients undergoing neoadjuvant chemotherapy (NAC) for the treatment of clinically node-negative (cN0) breast cancer has not been determined. We sought to determine the sequence of removal of the positive SLNs in this patient population. METHODS All patients aged ≥ 18 years diagnosed with cN0 invasive breast cancer who received NAC and underwent SLN surgery at Mayo Clinic Rochester between September 2008 and September 2018 were identified. Univariate analysis was performed to compare factors associated with positive nodes and where the first positive node was in the sequence of removal of the SLNs. RESULTS We identified 446 cancers among 440 patients with a median age of 51 (IQR: 43, 61) years. At surgery, 381 (85.4%) cancers were pathologically node (ypN) negative and 65 (14.6%) were pN + . The number of nodes removed was similar for both patients with ypN0 and ypN + disease, with a median number of SLNs removed of 2.0 (IQR: 2.0, 3.0). Of all patients with a positive node, the first positive node was most commonly the 1st node removed (75.4%), and was identified by the 3rd SLN removed in all cases. CONCLUSIONS Among cN0 patients treated with NAC, if a positive SLN is present, it is most commonly identified as the 1st sentinel node removed by the surgeon, and was identified by the 3rd sentinel node in our series. This suggests that once 3 SLNs have been resected, removal of additional sentinel lymph nodes does not add diagnostic value.

Abstract
Abstract
Triple negative breast cancer (TNBC) accounts for 15-20% of breast cancer cases in the United States. With currently no targeted therapies for TNBC, identification of novel biomarkers to improve chemo-response is vital. Recently, copy number amplifications (CNAs) have been implicated in treatment response in several diseases including breast cancer. Our clinical studies have associated a 5 Mb CNA in TNBC patients with chemo-response, which may elucidate novel biomarkers and treatment strategies for TNBC. Analysis of RNAseq and Whole Exome Sequencing data from 42 TNBC patient tumors enrolled in the BEAUTY Study, identified a 5 Mb CNA on chromosome 8q which associated with pathological complete response following taxane and anthracycline chemotherapy. By performing siRNA knockdown cytotoxicity studies in TNBC cell lines for genes within this amplified region, we identified RDH10 as a potential novel biomarker for increasing chemo-sensitivity. RDH10 is the rate limiting step in the synthesis of all-trans retinoic acid (ATRA). Previous studies have demonstrated ATRA to be a potent inhibitor of PIN1, a key regulator of several oncogenic signaling pathways, amplified in TNBC. We discovered overexpression of RDH10 to increase endogenous levels of ATRA, contributing to the degradation of PIN1 and taxane sensitivity. A rescue experiment with PIN1 was able to restore the chemo-resistance phenotype. Similarly, we found treating TNBC cells with ATRA phenocopied RDH10's effect on PIN1 and improved chemo-sensitivity. Furthermore, analyses of chemo-responsive PDX tumors containing the 5 Mb CNA, overexpressed RDH10 and exhibited lower levels of PIN1 when compared to non-responders. In conclusion, RDH10 amplification increases endogenous levels of ATRA and degrades PIN1 in TNBC. ATRA-mediated degradation of PIN1 sensitizes TNBC to chemotherapy, suggesting RDH10 as a novel biomarker for chemo-response and ATRA as a novel treatment to improve chemo-sensitivity.

Abstract
BACKGROUND Sentinel lymph node (SLN) surgery after neoadjuvant chemotherapy (NAC) has been well studied. However, outcomes data addressing the oncologic safety of this technique are sparse. This study aimed to evaluate use of SLN surgery versus axillary lymph node dissection (ALND) for clinically node-positive patients treated with NAC and to report outcomes. METHODS The study identified patients at the authors' institution with biopsy proven clinically node-positive (cN1-cN3) breast cancer undergoing axillary surgery after NAC from 2009 to 2019. Practice patterns and outcomes were evaluated. RESULTS Of 602 patients, 52.3% underwent SLN surgery. Use of SLN surgery increased significantly over time, reaching 75.3% during 2015-2019. For 52.5% of the patients who had an SLN identified, ALND was not used. Use of ALND (± SLN surgery) decreased from 100% in 2009 to 57.2% in 2015-2019. The nodal positivity rate of patients who proceeded directly to ALND was 64.5% (185/287), increasing significantly over time. Factors significantly associated with performing SLN surgery on multivariable analysis were lower presenting clinical T category, lower presenting clinical N category (cN1 vs cN2-3) and HER2-positive status. During the median 34-month follow-up period, 17 regional recurrences were observed (16/443 with ALND; 1/159 with SLN surgery alone), for a 2-year freedom-from-regional-recurrence rate of 99.1% among the SLN surgery patients and 96.4% among the ALND patients (p = 0.10). CONCLUSIONS For cN1-3 breast cancer treated with NAC, SLN surgery has been incorporated into clinical practice at the authors' institution. In this study, selection for SLN surgery was based on clinical factors and tumor biology. More than half of the patients who were selected for SLN surgery were spared ALND, with a low nodal failure rate and no recurrence-free survival disadvantage at 2 years.

Abstract
Breast cancer survivorship guidelines recommend at least annual follow-up visits, yet the degree to which this occurs in clinical practice is uncertain. Claims data from a US commercial insurance database (OptumLabs) were used to identify women treated with curative intent surgery for newly diagnosed breast cancer between 2006 and 2014. In 25 035 women, median follow-up was 3 years. In the second year after surgery, 9.6% of the patients did not visit a primary care provider, an oncologist, or a surgeon (guideline-nonadherent). The guideline-nonadherent proportion increased from 7.8% in women diagnosed in 2006 to 12.2% in those diagnosed in 2014 (two-sided Wald P < .001). During years 2-6, guideline-nonadherence was also associated with older age, nonwhite race, no radiation, no chemotherapy, no endocrine therapy, and increasing time after surgery. There is a substantial and increasing rate of inadequate follow-up among breast cancer survivors. This has the potential to impair outcomes.

Abstract
INTRODUCTION Prediction models are useful to guide decision making. Our goal was to compare three published nomograms predicting axillary response to neoadjuvant chemotherapy (NAC), clinically node-positive breast cancer. METHODS Patients with cT1-T4, cN1-N3 breast cancer treated with NAC and surgery from 2008 to 2019 were reviewed. The predicted probability of pathologic node-negative (ypN0) status was estimated for each nomogram. Area under the curve (AUC) was compared across models, overall and by biologic subtype. RESULTS Of 581 patients, 253 (43.5%) were ypN0. ypN0 status varied by subtype: 23.9% for estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-), 68.9% for HER2-positive (HER2+), and 47.2% for ER-negative (ER-)/HER2-. The three nomograms had similar AUC values (0.761-0.769; p = 0.80). The Mayo model-predicted probability was significantly lower (p < 0.001) than the observed probability of ypN0 status, while the MD Anderson Cancer Center (MDACC) 1- and 2-predicted probabilities were similar to the observed probability. At a predicted probability threshold of 50%, the Mayo model had the highest sensitivity (89.6%) for detecting ypN+ patients compared with MDACC models 1 and 2 (76.5%; p < 0.001). However, both MDACC models had higher specificity in identifying ypN0 status among HER2+ (81.7%) and ER-/HER2- (75.9-77.6%) patients compared with the Mayo model (59.5% and 43.1%; each p < 0.001). None of the models identified the ER+/HER2- patients with ypN0 status well at the ≥ 50% threshold (specificity 0-9.4%). CONCLUSION All three models predicting nodal response to NAC performed well overall with respect to discrimination, but differed with respect to calibration and performance at a 50% probability threshold. However, none of the models performed well at the 50% threshold for ER+/HER2- patients.

Abstract
Importance Most lymphedema studies include a heterogeneous population and focus on patients treated with adjuvant chemotherapy. Objective To examine factors associated with lymphedema after neoadjuvant chemotherapy (NAC) and axillary lymph node dissection in women with node-positive breast cancer. Design, Setting, and Participants This cohort study included data from 701 women 18 years or older with cT0-T4N1-2M0 breast cancer with documented axillary nodal metastasis at diagnosis who were enrolled in the American College of Surgeons Oncology Group Z1071 (Alliance for Clinical Trials in Oncology) trial, which took place from January 1, 2009, to December 31, 2012. Data analysis was performed from January 11, 2018, to November 9, 2018. Interventions All participants received NAC, breast operation, and axillary lymph node dissection. Participants underwent prospective arm measurements and symptom assessment after NAC completion and at 6-month intervals to 36 months postoperatively. Main Outcomes and Measures Factors associated with lymphedema were defined as self-reported arm heaviness or swelling (lymphedema symptoms) or an arm volume increase of 10% or more (V10) or 20% or more (V20). Results A total of 486 patients (mean [SD] age, 50.1 [10.8] years) were included in this study. Median follow-up for the 3 measures was 2.2 to 3.0 years. Cumulative lymphedema incidence at 3 years was 37.8% (95% CI, 33.1%-43.2%) for lymphedema symptoms, 58.4% (95% CI, 53.2%-64.1%) for V10, and 36.9% (95% CI, 31.9%-42.6%) for V20. Increasing body mass index (hazard ratio [HR], 1.04; 95% CI, 1.01-1.06) and NAC for 144 days or longer (HR, 1.48; 95% CI, 1.01-2.17) were associated with lymphedema symptoms. The V20 incidence was higher among patients who received NAC for 144 days or longer (HR, 1.79; 95% CI, 1.19-2.68). The V10 incidence was highest in patients with 30 nodes or more removed (HR, 1.70; 95% CI, 1.15-2.52) and increased with number of positive nodes (HR, 1.03; 95% CI, 1.00-1.06). On multivariable analysis, obesity was significantly associated with lymphedema symptoms (HR, 1.03; 95% CI, 1.01-1.06), and NAC length was significantly associated with V20 (HR, 1.74; 95% CI, 1.15-2.62). Conclusions and Relevance In this study, longer NAC duration and obesity were associated with increased lymphedema incidence, suggesting that patients in these groups may benefit from enhanced prospective lymphedema surveillance.

Abstract
BACKGROUND Reoperation rates following breast-conserving surgery (BCS) range from 10 to 40%, with marked surgeon and institutional variation. OBJECTIVE The aim of this study was to identify factors associated with intraoperative margin re-excision, evaluate for any differences in local recurrence based on margin re-excision and determine reoperation rates with use of intraoperative margin analysis. PATIENTS AND METHODS We analyzed consecutive patients with ductal carcinoma in situ (DCIS) or invasive breast cancer who underwent BCS at our institution between 1 January 2005 and 31 December 2016. Routine intraoperative frozen section margin analysis was performed and positive or close margins were re-excised intraoperatively. Univariate analysis was used to compare margin status and the Kaplan-Meier method was used to compare recurrence. Multivariable logistic regression was utilized to analyze factors associated with re-excision. RESULTS We identified 3201 patients who underwent BCS-688 for DCIS and 2513 for invasive carcinoma. Overall, 1513 (60.2%) patients with invasive cancer and 434 (63.1%) patients with DCIS had close or positive margins that underwent intraoperative re-excision. Margin re-excision was associated with larger tumor size in both groups. The permanent pathology positive margin rate among all patients was 1.2%, and the 30-day reoperation rate for positive margins was 1.1%. Five-year local recurrence rates were 0.6% and 1.2% for patients with DCIS and invasive cancer, respectively. There was no difference in recurrence between patients with and without intraoperative margin re-excision (p = 0.92). CONCLUSION Both DCIS and invasive carcinoma had similar rates of intraoperative margin re-excision. Although intraoperative margin re-excision was common, the reoperation rate was extremely low and there was no difference in recurrence between those with or without intraoperative re-excision.

Abstract
Programmed death ligand-1 (PD-L1 or B7-H1) is well known for its role in immune checkpoint regulation, but its function inside the tumor cells has rarely been explored. Here we report that nuclear PD-L1 is important for cancer cell sister chromatid cohesion. We found that depletion of PD-L1 suppresses cancer cell proliferation, colony formation in vitro, and tumor growth in vivo in immune-deficient NSG mice independent of its role in immune checkpoint. Specifically, PD-L1 functions as a subunit of the cohesin complex, and its deficiency leads to formation of multinucleated cells and causes a defect in sister chromatid cohesion. Mechanistically, PD-L1 compensates for the loss of Sororin, whose expression is suppressed in cancer cells overexpressing PD-L1. PD-L1 competes with Wing Apart-Like (WAPL) for binding to PDS5B, and secures proper sister chromatid cohesion and segregation. Our findings suggest an important role for nuclear PD-L1 in cancer cells independent of its function in immune checkpoint.

Abstract
PURPOSE To develop recommendations for management of patients with breast cancer (BC) with germline mutations in BC susceptibility genes. METHODS The American Society of Clinical Oncology, American Society for Radiation Oncology, and Society of Surgical Oncology convened an Expert Panel to develop recommendations based on a systematic review of the literature and a formal consensus process. RESULTS Fifty-eight articles met eligibility criteria and formed the evidentiary basis for the local therapy recommendations; six randomized controlled trials of systemic therapy met eligibility criteria. RECOMMENDATIONS Patients with newly diagnosed BC and BRCA1/2 mutations may be considered for breast-conserving therapy (BCT), with local control of the index cancer similar to that of noncarriers. The significant risk of a contralateral BC (CBC), especially in young women, and the higher risk of new cancers in the ipsilateral breast warrant discussion of bilateral mastectomy. Patients with mutations in moderate-risk genes should be offered BCT. For women with mutations in BRCA1/2 or moderate-penetrance genes who are eligible for mastectomy, nipple-sparing mastectomy is a reasonable approach. There is no evidence of increased toxicity or CBC events from radiation exposure in BRCA1/2 carriers. Radiation therapy should not be withheld in ATM carriers. For patients with germline TP53 mutations, mastectomy is advised; radiation therapy is contraindicated except in those with significant risk of locoregional recurrence. Platinum agents are recommended versus taxanes to treat advanced BC in BRCA carriers. In the adjuvant/neoadjuvant setting, data do not support the routine addition of platinum to anthracycline- and taxane-based chemotherapy. Poly (ADP-ribose) polymerase (PARP) inhibitors (olaparib and talazoparib) are preferable to nonplatinum single-agent chemotherapy for treatment of advanced BC in BRCA1/2 carriers. Data are insufficient to recommend PARP inhibitor use in the early setting or in moderate-penetrance carriers. Additional information available at www.asco.org/breast-cancer-guidelines.

Abstract
We explored the feasibility of obtaining accurate HLA type using pre-existing NGS data not generated for HLA purposes. 83 exomes and 500 targeted NGS pharmacogenomic panels were analyzed using Omixon HLA Explore, OptiType, and/or HLA-Genotyper software. Results were compared against clinical HLA genotyping. 765 (94.2%) Omixon and 769 (94.7%) HLA-Genotyper of 812 germline allele calls across class I/II loci and 402 (99.5%) of 404 OptiType class I calls were concordant to the second field (i.e. HLA-A*02:01). An additional 19 (2.3%) Omixon, 39 (4.8%) HLA-Genotyper, and 2 (0.5%) OptiType allele calls were first field concordant (i.e. HLA-A*02). Using Omixon, four alleles (0.4%) were discordant and 24 (3.0%) failed to call, while 4 alleles (0.4%) were discordant using HLA-Genotyper. Tumor exomes were also evaluated and were 85.4%, 91.6%, and 100% concordant (Omixon and HLA-Genotyper with 96 alleles tested, and Optitype with 48 class I alleles, respectively). The 15 exomes and 500 pharmacogenomic panels were 100% concordant for each pharmacogenomic allele tested. This work has broad implications spanning future clinical care (pharmacogenomics, tumor response to immunotherapy, autoimmunity, etc.) and research applications.
