Abstract
Loss of protein expression of the tumor suppressor PTEN is associated with increased cancer aggressiveness, decreased tumor immune infiltration, and resistance to immune and targeted therapies in melanoma. We assessed a unique cohort of eight melanoma samples with focal loss of PTEN protein expression to understand the features and mechanisms of PTEN loss in this disease. We compared the PTEN-negative (PTEN[-]) areas to their adjacent PTEN-positive (PTEN[+]) areas using DNA sequencing, DNA methylation, RNA expression, digital spatial profiling, and immunohistochemical platforms. Variations or homozygous deletions of PTEN were identified in PTEN(-) areas that were not detected in the adjacent PTEN(+) areas in three cases (37.5%), but no clear genomic or DNA methylation basis for loss was identified in the remaining PTEN(-) samples. RNA expression data from two independent platforms identified a consistent increase in chromosome segregation gene expression in PTEN(-) versus adjacent PTEN(+) areas. Proteomic analysis showed a relative paucity of tumor-infiltrating lymphocytes in PTEN(-) versus adjacent PTEN(+) areas. The findings add to our understanding of potential molecular intratumoral heterogeneity in melanoma and the features associated with the loss of PTEN protein in this disease.

Abstract
Introduction Undifferentiated pleomorphic sarcoma (UPS) can be associated with a relatively dense immune infiltration. Immune checkpoint inhibitors (anti-PD1, anti-PDL1, and anti-CTLA4) are effective in 20% of UPS patients. We characterize the immune microenvironment of UPS and its association with oncologic outcomes. Material and methods Surgically resected UPS samples were stained by immunohistochemistry (IHC) for the following: tumor-associated immune cells (CD3, CD8, CD163, CD20), immune checkpoints (stimulatory: OX40, ICOS; inhibitory: PD-L1, LAG3, IDO1, PD1), and the adenosine pathway (CD73, CD39). Sections were reviewed for the presence of lymphoid aggregates (LA). Clinical data were retrospectively obtained for all samples. The Wilcoxon rank-sum and Kruskal-Wallis tests were used to compare distributions. Correlations between biomarkers were measured by Spearman correlation. Univariate and multivariate Cox models were used to identify biomarkers associated with overall survival (OS) and disease-free survival (DFS). Unsupervised clustering was performed, and Kaplan-Meier curves and log-rank tests used for comparison of OS and DFS between immune clusters. Results Samples analyzed (n=105) included 46 primary tumors, 34 local recurrences, and 25 metastases. LA were found in 23% (n=10/43), 17% (n=4/24), and 30% (n=7/23) of primary, recurrent, and metastatic samples, respectively. In primary UPS, CD73 expression was significantly higher after preoperative radiation therapy (p=0.009). CD39 expression was significantly correlated with PD1 expression (primary: p=0.002, recurrent: p=0.004, metastatic: p=0.001), PD-L1 expression (primary: p=0.009), and CD3+ cell densities (primary: p=0.016, recurrent: p=0.043, metastatic: p=0.028). In recurrent tumors, there was a strong correlation between CD39 and CD73 (p=0.015), and both were also correlated with CD163+ cell densities (CD39 p=0.013; CD73 p<0.001). In multivariate analyses, higher densities of CD3+ and CD8+ cells (Cox Hazard Ratio [HR]=0.33; p=0.010) were independently associated with OS (CD3+, HR=0.19, p<0.001; CD8+, HR= 0.33, p=0.010) and DFS (CD3+, HR=0.34, p=0.018; CD8+, HR=0.34, p= 0.014). Unsupervised clustering of IHC values revealed three immunologically distinct clusters: immune high, intermediate, and low. In primary tumors, these clusters were significantly associated with OS (log-rank p<0.0001) and DFS (p<0.001). Conclusion We identified three immunologically distinct clusters of UPS Associated with OS and DFS. Our data support further investigations of combination anti-PD-1/PD-L1 and adenosine pathway inhibitors in UPS.

Abstract
BACKGROUND AND AIMS Cholangiocarcinoma (CCA) is a deadly and highly therapy-refractory cancer of the bile ducts, with early results from immune checkpoint blockade trials showing limited responses. Whereas recent molecular assessments have made bulk characterizations of immune profiles and their genomic correlates, spatial assessments may reveal actionable insights. APPROACH AND RESULTS Here, we have integrated immune checkpoint-directed immunohistochemistry with next-generation sequencing of resected intrahepatic CCA samples from 96 patients. We found that both T-cell and immune checkpoint markers are enriched at the tumor margins compared to the tumor center. Using two approaches, we identify high programmed cell death protein 1 or lymphocyte-activation gene 3 and low CD3/CD4/inducible T-cell costimulator specifically in the tumor center as associated with poor survival. Moreover, loss-of-function BRCA1-associated protein-1 mutations are associated with and cause elevated expression of the immunosuppressive checkpoint marker, B7 homolog 4. CONCLUSIONS This study provides a foundation on which to rationally improve and tailor immunotherapy approaches for this difficult-to-treat disease.

Abstract
4009 Background: IDH1/2 genetic aberrations (GA) occur in 20% of IHCC cases and may be specifically targeted by IDH inhibitors. The genomic and immunologic profile of IHCC with IDH1/2 GA remains undefined. IDH1 mutations impair DNA damage repair (DDR), loss of heterozygosity (LOH) and may represent a biomarker for DDR in these patients. Methods: Comprehensive genomic profiling (CGP) was performed in 3,067 cases of advanced stage IHCC using a hybrid capture-based FDA-approved assay. Tumor mutational burden (TMB) was determined on 0.8 Mbp of sequenced DNA and microsatellite instability (MSI) was determined on 95 loci. PD-L1 expression in tumor cells (Dako 22C3) was measured by immunohistochemistry (IHC). Genomic LOH (gLOH) was assessed for samples meeting quality criteria. Densities of tumor associated immune cells and immune-checkpoint markers expressed in epithelial malignant cells and in the tumor microenvironment of 100 surgical samples from 96 patients were evaluated by IHC using digital image analysis of 14 markers (CD3, CD4, CD8, CD68, PD1,PD-L1, B7-H4, B7-H3, IDO1, ICOS, VISTA, OX40, TIM3, LAG3). Tissue microarrays were generated for multiplex immune panel analysis. A p value < 0.05 was considered statistically significant. Results: 426 (14%) of IHCC were IDH1+ and 125 (4%) were IDH2+ (Table) and were mutually exclusive. All IDH1 GA occurred at the R132 locus and included R132C (69%) and R132L/G/S/H/F (16%/7%/4%/3%/ < 1%) and 119Q ( < 1%) and IDH2 GA at R172 (94.4%) and R140 (6.6%). IDH1+ and IDH2+ IHCC had fewer co-occurring targetable GA than IDH1/2 wildtype (WT, IDHwt) cases including FGFR2 rearrangements (RE) (P <.0001), ERBB2 (P =.0009) and BRAF (P =.04). Median gLOH were not significantly different between IDH1+ IDH2+ IHCC vs. IDHwt IHCC (p = 0.37). Potential biomarkers of immune checkpoint inhibition (ICI) response including MSI High, TMB > 10 mut/Mb, and PD-L1 positivity were more frequent in IDHwt IHCC than IDH1+ IHCC. 29/96 (30%) surgical patients were positive for IDH1/2 mutation though mutational status did not confer a statistically significant difference in the 14 immune biomarker panel expression. Conclusions: CGP reveals significant differences in GA between IDH1+, IDH2+ and IDHwt IHCC consistent with IDH1 and IDH2 being driver oncogenes for IHCC. Immune biomarker expression and gLOH did not differ significantly between IDH mutated and WT cases.[Table: see text]

Abstract
Background To date, no systemic therapy, including immunotherapy, exists to improve clinical outcomes in metastatic uveal melanoma (UM) patients. To understand the role of immune infiltrates in the genesis, metastasis, and response to treatment for UM, we systematically characterized immune profiles of UM primary and metastatic tumors, as well as samples from UM patients treated with immunotherapies. Methods Relevant immune markers (CD3, CD8, FoxP3, CD68, PD-1, and PD-L1) were analyzed by immunohistochemistry on 27 primary and 31 metastatic tumors from 47 patients with UM. Immune gene expression profiling was conducted by NanoString analysis on pre-treatment and post-treatment tumors from patients (n=6) receiving immune checkpoint blockade or 4-1BB and OX40 dual costimulation. The immune signature of UM tumors responding to immunotherapy was further characterized by Ingenuity Pathways Analysis and validated in The Cancer Genome Atlas data set. Results Both primary and metastatic UM tumors showed detectable infiltrating lymphocytes. Compared with primary tumors, treatment-naïve metastatic UM showed significantly higher levels of CD3+, CD8+, FoxP3+ T cells, and CD68+ macrophages. Notably, levels of PD-1+ infiltrates and PD-L1+ tumor cells were low to absent in primary and metastatic UM tumors. No metastatic organ-specific differences were seen in immune infiltrates. Our NanoString analysis revealed significant differences in a set of immune markers between responders and non-responders. A group of genes relevant to the interferon-γ signature was differentially up-expressed in the pre-treatment tumors of responders. Among these genes, suppressor of cytokine signaling 1 was identified as a marker potentially contributing to the response to immunotherapy. A panel of genes that encoded pro-inflammatory cytokines and molecules were expressed significantly higher in pre-treatment tumors of non-responders compared with responders. Conclusion Our study provides critical insight into immune profiles of UM primary and metastatic tumors, which suggests a baseline tumor immune signature predictive of response and resistance to immunotherapy in UM.

Abstract
Abstract
The purpose of this study was to determine the role of BAP1 levels in cutaneous melanoma (CM). BAP1 is a tumor suppressor in which loss of heterozygosity (LOH) from mutation and copy number alteration is well described in germline and somatic cancers. Although BAP1 genomic alterations in CM are extremely rare (2% of 665 samples from 5 datasets), marked variability in BAP1 expression is observed in CM. We show that low nuclear BAP1 levels portend a significantly worse clinical outcome in stage III CM (n=37, log rank p ≤0.01 for both overall survival and progression-free survival). Gene Set Enrichment Analysis (GSEA) revealed low BAP1 expression to be most highly ranked with an increased epithelial–mesenchymal transition (EMT) gene expression profile in CM tumors (n=379, FDR q = 1.34E-26) and cell lines (n=53, FDR q = 2.86E-116). We identify the expression of ZEB1, a master regulator of EMT, to be significantly associated with low BAP1 expression in CM tumors and cell lines (p= 1.5E-04 and 3.3E-05, respectively). Analysis of the BAP1 promoter indicates three canonical ZEB1 binding sites. Functional experiments show ZEB1 to bind to the BAP1 promoter, and luciferase activity assays indicate that ZEB1 acts as a transcriptional suppressor of BAP1 expression with differential utilization of the promoter binding sites. Targeted reduction of endogenous ZEB1 caused increased BAP1 levels, while targeted reduction of BAP1 did not modulate ZEB1 levels, consistent with ZEB1 having a suppressive effect on BAP1. Phenotypically, targeted reduction of BAP1 in CM cells resulted in a switch from a more differentiated, melanocytic state, to a less differentiated, more migratory and invasive phenotype. Extinguishing melanocyte-specific BAP1 in mice with a BRAF V600E mutant genetic background resulted in the emergence of primary melanoma tumors, with a marked EMT gene expression profile, and resultant metastases. Given the phenotypic changes associated with BAP1 levels in our mouse and human studies, we then tested the effect of modulating BAP1 on BRAF targeted therapy. Exogenous expression of BAP1 sensitized BRAF inhibitor (vemurafenib)-resistant melanoma cells, while the targeted reduction of BAP1 desensitized BRAF inhibitor-sensitive melanoma cells. BRAF mutant/BAP1 loss mice failed to exhibit a marked response to vemurafenib treatment compared to control mice. These data implicate regulation of BAP1 to be a major mechanism that characterizes a highly malignant and treatment-resistant subset of tumors. Our study indicates that nongenomic reduction in BAP1 through ZEB1 transcriptional modulation may be a key factor in aggressive CM.

Abstract
PURPOSE Intrahepatic cholangiocarcinoma (IHCCA), a global health problem, is increasing in incidence and has differing etiologies worldwide. Next-generation sequencing (NGS) is rapidly being incorporated into the clinical management of biliary cancers. IHCCA is enriched with actionable mutations, and there are several promising targeted therapies under development. NGS data from Asia, where IHCCA is most prevalent, are limited. METHODS Comprehensive genomic profiling of formalin-fixed paraffin-embedded tumor tissue from 164 Asian and 283 Western patients with IHCCA was performed using NGS. We measured the distribution of DNA repair genetic aberrations (GAs) in IHCCA, along with actionable mutations. Also, we evaluated the association between DNA repair GAs and tumor mutation burden (TMB). Based on the TMB status, patients were distinguished into 3 levels: low (< 6 mut/Mb), intermediate (6-10 mut/Mb), and high (TMB-H; ≥ 10 mut/Mb). RESULTS Seventy-two percent of Asian patients had ≥ 1 actionable GA, with a significantly higher frequency in KMT2C , BRCA1/2, and DDR2 compared with Western patients (P = .02, .003, and .003, respectively); 60.9% of Western patients had ≥ 1 actionable GA and higher frequency of CDKN2A/B and IDH1/2 GAs (P = .0004 and < .001, respectively). GAs in nuclear factor kappa B pathway regulators and DNA repair genes occurred more frequently in Asian patients (P = .006 and .001, respectively). There was a higher frequency of TMB-H in Asian compared with the Western cohort (12.2% v 5.9%; P = .07). CONCLUSION A higher burden of DNA repair mutations and frequency of patients with TMB-H in the Asian IHCCA cohort compared with the Western patients suggests a potential role for DNA repair and immune checkpoint inhibitors in the Asian population. Future clinical trials should account for this genetic heterogeneity.

Abstract
Complex tumor microenvironmental (TME) features influence the outcome of cancer immunotherapy (IO). Here we perform immunogenomic analyses on 67 intratumor sub-regions of a PD-1 inhibitor-resistant melanoma tumor and 2 additional metastases arising over 8 years, to characterize TME interactions. We identify spatially distinct evolution of copy number alterations influencing local immune composition. Sub-regions with chromosome 7 gain display a relative lack of leukocyte infiltrate but evidence of neutrophil activation, recapitulated in The Cancer Genome Atlas (TCGA) samples, and associated with lack of response to IO across three clinical cohorts. Whether neutrophil activation represents cause or consequence of local tumor necrosis requires further study. Analyses of T-cell clonotypes reveal the presence of recurrent priming events manifesting in a dominant T-cell clonotype over many years. Our findings highlight the links between marked levels of genomic and immune heterogeneity within the physical space of a tumor, with implications for biomarker evaluation and immunotherapy response.

Abstract
Abstract
Sustained periods of apparent clinical benefit despite lack of objective response are well known in a subpopulation of advanced melanoma patients. Inter-individual heterogeneity in response of separate tumors is common, characterizing complex overall response patterns. The molecular and cellular dynamics facilitating such long-term survival and heterogeneous response is poorly understood, particularly in the era of exposure to multiple potentially active therapies. We studied an exceptional case of long-term survival in a patient with non-responding metastatic melanoma in order to characterize the clonal and microenvironmental factors active across 3 time points.
We performed immunogenomic analyses of 3 metachronous tumors, including a systemic therapy-naïve mass, 67 intratumor sub-regions of a non-responding mass during PD-1 inhibitor therapy, and a post-PD-1 inhibitor mass. We profiled samples using whole exome sequencing, RNA-sequencing (RNA-seq), immunohistochemistry (IHC), and T cell receptor sequencing. Longitudinal, spatial, and cross-modal analyses were performed.
Longitudinal analyses identified mutations in several genes known to be associated with targeted or immune therapy resistance affecting distinct metastases. Genomic intratumoral heterogeneity (ITH) was primarily driven by subclonal copy number alterations that showed evidence of spatially-distinct evolution which may be in response to selective pressures at the tumor margin. RNA-seq revealed an unexpectedly high degree of ITH characterized by limited group-level gene or pathway associations with physical or immune characteristics of each site. Spatially-distinct pockets of immune activation and suppression were observed throughout the PD-1 inhibitor resistant metastasis despite a largely immune-excluded phenotype seen on IHC. A specific T cell Vβ CDR3 rearrangement was identified as dominant and recurrent not only across multiple spatial points within a single tumor mass, but also across metachronous tumors spanning the patient’s disease course. Immunophenotyping of the T cell population with single-cell RNA-seq suggested repeated T-cell priming events leading to the persistence of both activated and exhausted T cells bearing the same TCR-β at any given time.
Our findings highlight an unexpected level of genomic and immune heterogeneity in metastatic melanoma tumors of a long-term surviving patient. The observed degree of ITH across local tumor microenvironments reiterates the inherent limitations to identifying robust and reproducible predictive biomarkers of therapy response based on limited physical sampling of tumors. Further spatiotemporal analysis of metastatic lesions in the context of immune checkpoint blockade will be required to determine how the mechanisms driving convergent microenvironmental phenotypes may be harnessed for therapeutic gain.

Abstract
Abstract
Combined MEK and CDK4/6 inhibition (MEKi+CDK4i) has shown promising clinical outcomes in NRAS mutant melanoma patients. Here, we interrogated longitudinal biopsies from a patient who initially responded to MEKi+CDK4i therapy but subsequently developed resistance. Whole exome sequencing and functional validation identified an acquired PIK3CAE545K mutation as conferring drug resistance. We demonstrate that PIK3CAE545K pre-existed in a rare subpopulation that was missed by both clinical and research testing, but was revealed upon multi-region sampling due to PIK3CAE545K being non-uniformly distributed. This resistant population rapidly expanded after the initiation of MEKi+CDK4i therapy and persisted in all successive samples even after immune checkpoint therapy. Functional studies identified activated S6K1 as both a key marker and specific therapeutic vulnerability downstream of PIK3CAE545K-induced resistance. These results demonstrate that comprehensive analysis of pre-treatment samples can reveal rare pre-existing resistant subpopulations and posit S6K1 as a common downstream therapeutic nexus for the MAPK, CDK4/6, and PI3K pathways.

Abstract
Abstract
BACKGROUND: MBMs are a common and lethal complication of advanced melanoma. An improved understanding of the molecular features of MBMs could facilitate the development of more effective treatments for patients (pts). Further, identification of differences between MBMs and ECMs would indicate the need for organ-specific treatment strategies.
METHODS: Transcriptomic capture and Illumina RNA-sequencing (RNA-seq) were performed on (i) surgically resected formalin-fixed, paraffin-embedded (FFPE) MBMs (98 tumors from 84 pts) and (ii) surgically-resected ECMs from the same pts (54 from 38 pts). The EdgeR/limma/voom pipeline was used to perform differential gene expression (DGE) analyses. Pathway analyses were performed via Ensemble Gene Set Enrichment Analysis (EGSEA). The ESTIMATE and MCPCounter R packages were used to assess immune infiltrates from voom-transformed counts. Illumina whole exome sequencing (WES) was performed on 27 matched pairs of MBMs and ECMs from 17 pts. MuTect algorithm was utilized to assess non-synonymous, stop-gain, and stop-loss mutations. DNA methylation profiling was performed on 16 pt-matched pairs of MBMs and ECMs by the Illumina MethylationEPIC BeadChip platform; data was analyzed via the ChAMP pipeline. Quantitative analysis of CD3 and CD8 immune markers was performed by immunohistochemistry (IHC) on 31 MBMs and 49 pt-matched ECMs.
RESULTS: Overall patterns of mRNA expression, mutational burden, and gene methylation were largely similar between pt-matched pairs of MBMs and ECMs, as unsupervised hierarchical clustering was driven primarily by patient identification. However, EGSEA of RNA-seq data identified significant (FDR q-value < 0.10) differences in immune networks (decreased in MBMs) and neuronal differentiation factors (increased in MBMs) in the pt-matched tumors. MCPCounter analysis revealed significant (p < 0.05) depletion of all classes of immune cells except neutrophils in MBMs compared to ECMs. IHC confirmed decreased TCD3 (p = 0.005) and TCD8 (p = 0.013) infiltrating cells in MBMs. ESTIMATE ImmuneScores among MBMs inversely correlated with expression of VSIG4, a relative of the B7 family believed to inhibit T-cell proliferation, and were significantly (p = 0.0088) increased in MBMs previously treated with radiation (XRT). Increased ImmuneScores also associated with significantly (p = 0.00002) improved overall survival (OS) from surgery for MBM. Significant correlations in mean promoter region methylation changes and RNA-seq log fold-changes were identified in 5/10 (50%) of the neuronal factors overexpressed in MBMs, suggesting an epigenetic mechanism for their differential expression.
CONCLUSIONS: Significant differences in immune and neuronal gene networks were detected in MBMs compared to patient-matched ECMs, and expression of immune genes in MBMs positively correlated with previous XRT and OS.
