Although the development of multiple primary tumors in smokers with lung cancer can be attributed to carcinogen-induced field cancerization, the occurrence of multiple tumors at presentation in individuals with EGFR-mutant lung cancer who lack known environmental exposures remains unexplained. In the present study, we identified ten patients with e...
Post-translational modifications (PTMs) play key roles in regulating cell signaling and physiology in both normal and cancer cells. Advances in mass spectrometry enable high-throughput, accurate, and sensitive measurement of PTM levels to better understand their role, prevalence, and crosstalk. Here, we analyze the largest collection of proteogenom...
Tumor microenvironments (TMEs) influence cancer progression but are complex and often differ between patients. Considering that microenvironment variations may reveal rules governing intratumoral cellular programs and disease outcome, we focused on tumor-to-tumor variation to examine 52 head and neck squamous cell carcinomas. We found that macropha...
The development of targeted therapy for patients with Multiple Myeloma (MM) is hampered by the low frequency of actionable genetic abnormalities. Gain or amplification of chr1q (Amp1q) is the most frequent arm-level copy number gain in patients with MM, and it is associated with higher risk of progression and death despite recent advances in therap...
Cancer driver events refer to key genetic aberrations that drive oncogenesis; however, their exact molecular mechanisms remain insufficiently understood. Here, our multi-omics pan-cancer analysis uncovers insights into the impacts of cancer drivers by identifying their significant cis-effects and distal trans-effects quantified at the RNA, protein,...
The National Cancer Institute's Clinical Proteomic Tumor Analysis Consortium (CPTAC) investigates tumors from a proteogenomic perspective, creating rich multi-omics datasets connecting genomic aberrations to cancer phenotypes. To facilitate pan-cancer investigations, we have generated harmonized genomic, transcriptomic, proteomic, and clinical data...
We introduce a pioneering approach that integrates pathology imaging with transcriptomics and proteomics to identify predictive histology features associated with critical clinical outcomes in cancer. We utilize 2,755 H&E-stained histopathological slides from 657 patients across 6 cancer types from CPTAC. Our models effectively recapitulate distinc...
Children with acute lymphoblastic leukemia (ALL) undergoing anti-CD19 therapy occasionally develop acute myeloid leukemia (AML). The clonal origin of such lineage-switch leukemias1–4 remains unresolved. Here, we reconstructed the phylogeny of multiple leukemias in a girl who, following multiply relapsed ALL, received anti-CD19 cellular and antibody...
Acquired drug resistance to anticancer targeted therapies remains an unsolved clinical problem. Although many drivers of acquired drug resistance have been identified1–4, the underlying molecular mechanisms shaping tumour evolution during treatment are incompletely understood. Genomic profiling of patient tumours has implicated apolipoprotein B mes...
BACKGROUND
Diffuse midline gliomas (DMGs) are a universally fatal brain tumor of childhood. While histone mutations are a critical tumor initiating event, they are insufficient to drive gliomagenesis. Histone mutations co-occur with somatic alterations in other pathways including TP53, MAPK, and MYC signaling. However, the mechanisms through which...

Background: High TMB is associated with immune checkpoint inhibitor (ICI) response in many solid tumors. However, obtaining sufficient tumor specimens for testing in a routine clinical setting could be a challenge. We evaluated TMB from whole-exome sequencing (WES) of cfDNA as a surrogate for tDNA TMB in R/M HNSCC pts treated with C+N. Methods...
MYC deregulation occurs in 67% of multiple myeloma (MM) cases and associates with progression and worse prognosis in MM. Enhanced MYC expression is known to be driven by translocation or amplification events, but it only occurs in 40% of MM patients. Here, we describe a new mechanism of MYC regulation, whereby epigenetic regulation of MYC by increa...
Although BCL2 mutations are reported as later occurring events leading to venetoclax resistance, many other mechanisms of progression have been reported but remain poorly understood. Here we analyze longitudinal tumor samples from eleven patients with disease progression on venetoclax to characterize the clonal evolution of resistance. All patients...
Purpose:
Checkpoint-inhibitors have limited efficacy for children with unselected solid and brain tumors. We report the first prospective pediatric trial (NCT02992964) using nivolumab exclusively for refractory non-hematological cancers harboring tumor mutation burden (TMB) ≥5 mutations/megabase (mut/Mb) and/or mismatch-repair deficiency (MMRD)....
Analysis of premalignant tissue has identified the typical order of somatic events leading to invasive tumors in several cancer types. For other cancers, premalignant tissue is unobtainable, leaving genetic progression unknown. Here, we demonstrate how to infer progression from exome sequencing of primary tumors. Our computational method, PhylogicN...
Purpose:
Monoclonal antibodies targeting the PD-1/PD-L1 immune checkpoint are powerful tools to improve the survival of cancer patients. Understanding the molecular basis of clinical response to these treatments is critical to identify patients who can benefit from this immunotherapy. In this study, we investigated long non-coding RNA (lncRNA) exp...
Anti-PD-1/PD-L1 agents have transformed the treatment landscape of advanced non-small cell lung cancer (NSCLC). To expand our understanding of the molecular features underlying response to checkpoint inhibitors in NSCLC, we describe here the first joint analysis of the Stand Up To Cancer-Mark Foundation cohort, a resource of whole exome and/or RNA...
Comprehensive characterization of tumor evolution is essential for understanding the drivers of metastasis and treatment resistance, which are still largely unknown. Studying evolution and resistance requires large cohorts of patients; for each patient, a comprehensive phylogenetic tree is used to follow clones over time and space. Deep whole-genom...
Drug resistance and disease recurrence represent a major obstacle in the treatment of high-grade serous ovarian cancer (HGSOC). Here, we performed a comprehensive characterization, at the single-cell level, of residual (persister) cancer cells that survive neoadjuvant treatment in HGSOC and can give rise to future recurrences. We aim to understand...
Detection of multiple primary lung cancers is increasing in frequency, with up to 15% of all non-small cell lung cancer (NSCLC) patients presenting with two or more anatomically separate tumor nodules on CT scans. Increased detection is in part due to expanded lung cancer screening criteria in an aging population. Distinguishing multiple primary tu...
Responders to checkpoint blockade in Non Small Cell Lung Cancer (NSCLC) often feature an inflamed microenvironment prior to therapy. However, the complete set of molecular drivers connecting this histologic observation to enhanced tumor clearance remain enigmatic.
In updated analysis of the Stand Up 2 Cancer-Mark Foundation (SU2C-MARK) Cohort - a c...
Background: Diffuse midline gliomas (DMGs) are a universally fatal brain tumor of childhood. While histone mutations are a critical tumor initiating event, they are insufficient to drive gliomagenesis. Histone mutations co-occur with somatic alterations in other pathways including TP53, MAPK, and MYC signaling. However, the mechanisms through which...
Post-translational modifications (PTMs) play key roles in regulating cell signaling in health and disease processes. Recent advances in mass spectrometry enable comprehensive investigation of PTMs. However, identifying functionally relevant PTMs and protein domains implicated in disease remains a key challenge. We present CLUMPS-PTM, an algorithm f...
Introduction
Patients with hematological malignancies, including multiple myeloma (MM), experience sub-optimal responses to SARS-CoV-2 vaccination. Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smoldering Multiple Myeloma (SMM) are precursors to MM and exhibit altered immune cell composition and function. The SARS-CoV-2 pandemic and...
Background. Despite substantial progress in the treatment of HER2+ MBC, most patients (pts) still experience disease progression and cancer-related death. HER2-directed TKIs are highly effective therapies for pts with HER2+ MBC; however, an understanding of resistance mechanisms is needed. Pts receiving HER2-directed TKIs with cell-free DNA (cfDNA)...
Despite the introduction of a number of new therapeutic classes including targeted inhibitors, immunotherapy, and antibody-drug conjugates, the ability to achieve long-term disease control in the majority of patients with advanced cancer remains elusive due to the emergence of resistance. While our understanding of resistance mechanisms continues t...
Women who harbor germline heterozygous mutations of BRCA1 or BRCA2 have a high risk of breast cancer. Our previous study showed that patient-derived, ostensibly normal BRCA2mut/+ luminal progenitor (LP) cells are more prone to exhibit sub-chromosomal copy number variations and associated DNA damage relative to non-carriers potentially reflecting ea...
Background Antibody drug conjugates (ADC) are novel drugs linking potent payloads to antibodies targeting antigen-expressing tumors. Sacituzumab govitecan (SG), targeting Trop-2, is approved for metastatic triple negative breast cancer (TNBC); and trastuzumab deruxtecan, targeting HER2, is approved for HER2-positive and HER2-low metastatic breast c...
Osteosarcoma (OS) and Leiomyosarcoma (LMS) are sarcomas with complex genomes for which there has been limited progress in identifying new treatments and improving outcomes. Slow progress in OS and LMS is partially due to insufficient characterization of the genomic landscape. Generating large genomic datasets in OS and LMS is challenging because of...
Cancer drug persistence allows small fractions of otherwise drug-sensitive populations of cancer cells to survive treatment with anti-cancer drugs. Unlike drug resistance, persistence mechanisms are not driven by genetic mutations, and are thus considered reversible after a ‘drug holiday’ period. While most persistent cells remain in cell cycle arr...
Somatic mutations in cancer genomes are caused by multiple mutational processes, each of which generates a characteristic mutational signature1. Here, as part of the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium2 of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA), we characterized mutational signatures...
Richter syndrome (RS) arising from chronic lymphocytic leukemia (CLL) exemplifies an aggressive malignancy that develops from an indolent neoplasm. To decipher the genetics underlying this transformation, we computationally deconvoluted admixtures of CLL and RS cells from 52 patients with RS, evaluating paired CLL–RS whole-exome sequencing data. We...
Multiple myeloma (MM) develops from well-defined precursor stages; however, invasive bone marrow (BM) biopsy limits screening and monitoring strategies for patients. We enumerated circulating tumor cells (CTC) from 261 patients (84 monoclonal gammopathy of undetermined significance, 155 smoldering multiple myeloma, and 22 MM), with neoplastic cells...
Transformation to aggressive disease histologies generates formidable clinical challenges across cancers, but biological insights remain few. We modeled the genetic heterogeneity of chronic lymphocytic leukemia (CLL) through multiplexed in vivo CRISPR-Cas9 B-cell editing of recurrent CLL loss-of-function drivers in mice and recapitulated the proces...
Multiple myeloma is a plasma cell malignancy almost always preceded by precursor conditions, but low tumor burden of these early stages has hindered the study of their molecular programs through bulk sequencing technologies. Here, we generate and analyze single cell RNA-sequencing of plasma cells from 26 patients at varying disease stages and 9 hea...
Background
Chimeric antigen receptor T-cell (CAR-T) therapy has shown unprecedented treatment outcomes for B-cell malignancies. The wider utilization of CAR-T, however, is limited by CAR-T-induced adverse events including cytokine release syndrome (CRS). Tocilizumab, a monoclonal antibody blocking Interleukin (IL)-6 receptor, is the only approved t...
Patients with smoldering multiple myeloma (SMM) are observed until progression, but early treatment may improve outcomes. We conducted a phase II trial of elotuzumab, lenalidomide, and dexamethasone (EloLenDex) in patients with high-risk SMM and performed single-cell RNA and T cell receptor (TCR) sequencing on 149 bone marrow (BM) and peripheral bl...
Multiple coronaviruses have emerged independently in the past 20 years that cause lethal human diseases. Although vaccine development targeting these viruses has been accelerated substantially, there remain patients requiring treatment who cannot be vaccinated or who experience breakthrough infections. Understanding the common host factors necessar...
PURPOSE Diagnosis of Mismatch Repair Deficiency (MMRD) is crucial for tumor management and early detection in patients with the cancer predisposition syndrome constitutional mismatch repair deficiency (CMMRD). Current diagnostic tools are cumbersome and inconsistent both in childhood cancers and in determining germline MMRD.

Anticancer therapies have been limited by the emergence of mutations and other adaptations. In bacteria, antibiotics activate the SOS response, which mobilizes error-prone factors that allow for continuous replication at the cost of mutagenesis. We investigated whether the treatment of lung cancer with EGFR inhibitors (EGFRi) similarly engages hype...
Multiple myeloma (MM) is an incurable plasma cell malignancy with a heterogeneous genetic background. Each MM subtype may have its own therapeutic vulnerabilities, and tailored therapy could improve outcomes. However, the cumulative frequency of druggable targets across patients is very low, which has precluded the widespread adoption of precision...
Forkhead box R2 (FOXR2) is a forkhead transcription factor located on the X chromosome whose expression is normally restricted to the testis. In this study, we performed a pan-cancer analysis of FOXR2 activation across more than 10,000 adult and pediatric cancer samples and found FOXR2 to be aberrantly upregulated in 70% of all cancer types and 8%...
