    Abstract: Breast, ovarian, and prostate cancers are hormone-related and may have a shared genetic basis, but this has not been investigated systematically by genome-wide association (GWA) studies. Meta-analyses combining the largest GWA meta-analysis data sets for these cancers totaling 112,349 cases and 116,421 controls of European ancestry, all together and in pairs, identified at P & lt; 10−8 seven new cross-cancer loci: three associated with susceptibility to all three cancers (rs17041869/2q13/BCL2L11; rs7937840/11q12/INCENP; rs1469713/19p13/GATAD2A), two breast and ovarian cancer risk loci (rs200182588/9q31/SMC2; rs8037137/15q26/RCCD1), and two breast and prostate cancer risk loci (rs5013329/1p34/NSUN4; rs9375701/6q23/L3MBTL3). Index variants in five additional regions previously associated with only one cancer also showed clear association with a second cancer type. Cell-type–specific expression quantitative trait locus and enhancer–gene interaction annotations suggested target genes with potential cross-cancer roles at the new loci. Pathway analysis revealed significant enrichment of death receptor signaling genes near loci with P & lt; 10−5 in the three-cancer meta-analysis. Significance: We demonstrate that combining large-scale GWA meta-analysis findings across cancer types can identify completely new risk loci common to breast, ovarian, and prostate cancers. We show that the identification of such cross-cancer risk loci has the potential to shed new light on the shared biology underlying these hormone-related cancers.

    Abstract: Accumulating evidence suggests a relationship between endometrial cancer and ovarian cancer. Independent genome-wide association studies (GWAS) for endometrial cancer and ovarian cancer have identified 16 and 27 risk regions, respectively, four of which overlap between the two cancers. We aimed to identify joint endometrial and ovarian cancer risk loci by performing a meta-analysis of GWAS summary statistics from these two cancers. Methods: Using LDScore regression, we explored the genetic correlation between endometrial cancer and ovarian cancer. To identify loci associated with the risk of both cancers, we implemented a pipeline of statistical genetic analyses (i.e., inverse-variance meta-analysis, colocalization, and M-values) and performed analyses stratified by subtype. Candidate target genes were then prioritized using functional genomic data. Results: Genetic correlation analysis revealed significant genetic correlation between the two cancers (rG = 0.43, P = 2.66 × 10−5). We found seven loci associated with risk for both cancers (PBonferroni & lt; 2.4 × 10−9). In addition, four novel subgenome-wide regions at 7p22.2, 7q22.1, 9p12, and 11q13.3 were identified (P & lt; 5 × 10−7). Promoter-associated HiChIP chromatin loops from immortalized endometrium and ovarian cell lines and expression quantitative trait loci data highlighted candidate target genes for further investigation. Conclusions: Using cross-cancer GWAS meta-analysis, we have identified several joint endometrial and ovarian cancer risk loci and candidate target genes for future functional analysis. Impact: Our research highlights the shared genetic relationship between endometrial cancer and ovarian cancer. Further studies in larger sample sets are required to confirm our findings.

    Abstract: Large-scale genome-wide association studies (GWAS) have identified approximately 35 loci associated with epithelial ovarian cancer (EOC) risk. The majority of GWAS-identified disease susceptibility variants are located in noncoding regions, and causal genes underlying these associations remain largely unknown. Here, we performed a transcriptome-wide association study to search for novel genetic loci and plausible causal genes at known GWAS loci. We used RNA sequencing data (68 normal ovarian tissue samples from 68 individuals and 6,124 cross-tissue samples from 369 individuals) and high-density genotyping data from European descendants of the Genotype-Tissue Expression (GTEx V6) project to build ovarian and cross-tissue models of genetically regulated expression using elastic net methods. We evaluated 17,121 genes for their cis-predicted gene expression in relation to EOC risk using summary statistics data from GWAS of 97,898 women, including 29,396 EOC cases. With a Bonferroni-corrected significance level of P & lt; 2.2 × 10−6, we identified 35 genes, including FZD4 at 11q14.2 (Z = 5.08, P = 3.83 × 10−7, the cross-tissue model; 1 Mb away from any GWAS-identified EOC risk variant), a potential novel locus for EOC risk. All other 34 significantly associated genes were located within 1 Mb of known GWAS-identified loci, including 23 genes at 6 loci not previously linked to EOC risk. Upon conditioning on nearby known EOC GWAS-identified variants, the associations for 31 genes disappeared and three genes remained (P & lt; 1.47 × 10−3). These data identify one novel locus (FZD4) and 34 genes at 13 known EOC risk loci associated with EOC risk, providing new insights into EOC carcinogenesis. Significance: Transcriptomic analysis of a large cohort confirms earlier GWAS loci and reveals FZD4 as a novel locus associated with EOC risk. Cancer Res; 78(18); 5419–30. ©2018 AACR.

    Abstract: Background: Genome-wide association studies (GWAS) have so far reported 12 loci associated with serous epithelial ovarian cancer (EOC) risk. We hypothesized that some of these loci function through nearby transcription factor (TF) genes and that putative target genes of these TFs as identified by coexpression may also be enriched for additional EOC risk associations. Methods: We selected TF genes within 1 Mb of the top signal at the 12 genome-wide significant risk loci. Mutual information, a form of correlation, was used to build networks of genes strongly coexpressed with each selected TF gene in the unified microarray dataset of 489 serous EOC tumors from The Cancer Genome Atlas. Genes represented in this dataset were subsequently ranked using a gene-level test based on results for germline SNPs from a serous EOC GWAS meta-analysis (2,196 cases/4,396 controls). Results: Gene set enrichment analysis identified six networks centered on TF genes (HOXB2, HOXB5, HOXB6, HOXB7 at 17q21.32 and HOXD1, HOXD3 at 2q31) that were significantly enriched for genes from the risk-associated end of the ranked list (P & lt; 0.05 and FDR & lt; 0.05). These results were replicated (P & lt; 0.05) using an independent association study (7,035 cases/21,693 controls). Genes underlying enrichment in the six networks were pooled into a combined network. Conclusion: We identified a HOX-centric network associated with serous EOC risk containing several genes with known or emerging roles in serous EOC development. Impact: Network analysis integrating large, context-specific datasets has the potential to offer mechanistic insights into cancer susceptibility and prioritize genes for experimental characterization.

    Abstract: Background: Testicular germ cell tumors (TGCT) are the most common cancers in young men of European ancestry aged 20 to 39 years. The incidence of TGCT has doubled over the past 20 years, yet no robust environmental risk factors for disease have been identified. Although TGCTs are treatable by surgery, radiation, and platinum-based chemotherapy, multiple long-term toxicities of treatment often occur impacting morbidity and mortality. Due to their high heritability and homogenous cell of origin, TGCTs are well suited to genome-wide association methods. The Testicular Cancer Consortium (TECAC) has brought together the largest genome-wise association study (GWAS) study of TGCT to date. Methods: We conducted a GWAS of 5,602 cases and 5,006 controls aggregated from 12 locations in the US and Europe. Logistic regression models adjusted for study center and genomic ancestry. Genotypes were imputed against the Human Haplotype Reference Consortium. Meta-analysis was performed to combine GWAS results with summary statistics from five previously published TGCT studies, UK Biobank, deCODE Genetics, and an independent set of cases and controls, for a total of 10,156 cases and 179,683 controls. Biologic function of loci was explored using PAINTOR annotated with ATAC-seq data of four TGCT cell lines, SPATIAL-seq data of the NTERA2 TGCT cell-line, and publicly available data from ENCODE. Polygenic risk scores (PRS) were computed using subject-level data from the 5,602 cases and 5,006 controls, and effect sizes of the novel hits derived from the meta-analysis. Results: 22 novel and 45 previously reported loci associated with TGCT surpassed genome-wide significance (p & lt; 5e-08). We discovered additional markers in known susceptibility loci and identified novel regions associated with germ cell development and sex determination (e.g., BCL11, AR), immune function (e.g., TNXB, ITIH5), and for the first time identified genes associated with kinetochore activity (e.g., PPP2R5A, ANAPC2). All identified risk SNPs to date account for 42.3% of heritability. Men in the highest 1% of PRS had over a 15-fold increased risk of TGCT compared to those at the median PRS, and PRS overall had an AUC of 74.29%. Conclusions: Results from our TGCT meta-analysis continue to provide insights into biological pathways affecting germ cell specification, expression, and epigenetic reprogramming, and sex determination. Our results also uniquely place TGCT as the only cancer type in which inherited variants implicating kinetochore activity, critical for chromosomal segregation, have been identified.

    Abstract LB-016: Radiochemotherapy combined with NK cells followed by a second-line PD-1 inhibition in a patients with NSCLC stage IIIb induces long-term tumor control

    Abstract: Advanced stage NSCLC is a fatal disease with poor prognosis. Following radiochemotherapy (RCT) tumor progression occurs after 5.6 months in stage III NSCLC patients. We identified membrane heat shock protein 70 (mHsp70) as a biomarker for high-risk NSCLC. Furthermore, mHsp70 serves as a tumor-specific target for NK cells that had been stimulated with Hsp70-peptide (TKD) and IL-2. In this study, a patient with mHsp70 positive inoperable NSCLC (cT4, cN3, cM0, stage IIIb) was treated for the first time with a combined therapy consisting of RCT (64.8 Gy), 4 cycles of mHsp70-targeting, autologous NK cells and PD-1 antibody, as a second-line therapy. Adoptive transfer of ex vivo Hsp70-activated NK cells after RCT combined with PD-1 inhibition was well tolerated and resulted in a superior OS. No viable tumor cells, but a massive immune cell infiltration of T and NK cells in fibrotic tissue were detected after therapy. Neither tumor progression nor distant metastases were detectable by CT-scanning 35 months after diagnosis. Therapy response was associated with significantly increased CD3-/NKG2D+/CD94+ NK cell counts, elevated CD8+ to CD4+ T cell, CD3-/CD56bright to CD3-/CD56dim NK cell ratios, and significantly reduced regulatory T cells (Tregs) in the peripheral blood. In summary, a combined immunotherapy consisting of RCT, mHsp70-targeting NK cells and PD-1 antibody inhibition is well tolerated, induces anti-tumor immune responses and results in long-term tumor control in a patient with advanced NSCLC.

    Abstract: DNA methylation is instrumental for gene regulation. Global changes in the epigenetic landscape have been recognized as a hallmark of cancer. However, the role of DNA methylation in epithelial ovarian cancer (EOC) remains unclear. In this study, high-density genetic and DNA methylation data in white blood cells from the Framingham Heart Study (N = 1,595) were used to build genetic models to predict DNA methylation levels. These prediction models were then applied to the summary statistics of a genome-wide association study (GWAS) of ovarian cancer including 22,406 EOC cases and 40,941 controls to investigate genetically predicted DNA methylation levels in association with EOC risk. Among 62,938 CpG sites investigated, genetically predicted methylation levels at 89 CpG were significantly associated with EOC risk at a Bonferroni-corrected threshold of P & lt; 7.94 × 10−7. Of them, 87 were located at GWAS-identified EOC susceptibility regions and two resided in a genomic region not previously reported to be associated with EOC risk. Integrative analyses of genetic, methylation, and gene expression data identified consistent directions of associations across 12 CpG, five genes, and EOC risk, suggesting that methylation at these 12 CpG may influence EOC risk by regulating expression of these five genes, namely MAPT, HOXB3, ABHD8, ARHGAP27, and SKAP1. We identified novel DNA methylation markers associated with EOC risk and propose that methylation at multiple CpG may affect EOC risk via regulation of gene expression. Significance: Identification of novel DNA methylation markers associated with EOC risk suggests that methylation at multiple CpG may affect EOC risk through regulation of gene expression.

    Risk of Ovarian Cancer and the NF-κB Pathway: Genetic Association with IL1A and TNFSF10
    American Association for Cancer Research (AACR) ; 2014

    Abstract: A missense single-nucleotide polymorphism (SNP) in the immune modulatory gene IL1A has been associated with ovarian cancer risk (rs17561). Although the exact mechanism through which this SNP alters risk of ovarian cancer is not clearly understood, rs17561 has also been associated with risk of endometriosis, an epidemiologic risk factor for ovarian cancer. Interleukin-1α (IL1A) is both regulated by and able to activate NF-κB, a transcription factor family that induces transcription of many proinflammatory genes and may be an important mediator in carcinogenesis. We therefore tagged SNPs in more than 200 genes in the NF-κB pathway for a total of 2,282 SNPs (including rs17561) for genotype analysis of 15,604 cases of ovarian cancer in patients of European descent, including 6,179 of high-grade serous (HGS), 2,100 endometrioid, 1,591 mucinous, 1,034 clear cell, and 1,016 low-grade serous, including 23,235 control cases spanning 40 studies in the Ovarian Cancer Association Consortium. In this large population, we confirmed the association between rs17561 and clear cell ovarian cancer [OR, 0.84; 95% confidence interval (CI), 0.76–0.93; P = 0.00075], which remained intact even after excluding participants in the prior study (OR, 0.85; 95% CI, 0.75–0.95; P = 0.006). Considering a multiple-testing–corrected significance threshold of P & lt; 2.5 × 10−5, only one other variant, the TNFSF10 SNP rs6785617, was associated significantly with a risk of ovarian cancer (low malignant potential tumors OR, 0.85; 95% CI, 0.79–0.91; P = 0.00002). Our results extend the evidence that borderline tumors may have a distinct genetic etiology. Further investigation of how these SNPs might modify ovarian cancer associations with other inflammation-related risk factors is warranted. Cancer Res; 74(3); 852–61. ©2013 AACR.

    Abstract: To implement noninvasive thermometry, we installed a hybrid system consisting of a radiofrequency multiantenna applicator (SIGMA-Eye) for deep hyperthermia (BSD-2000/3D) integrated into the gantry of a 1.5 Tesla magnetic resonance (MR) tomograph Symphony. This system can record MR data during radiofrequency heating and is suitable for application and evaluation of methods for MR thermography. In 15 patients with preirradiated pelvic rectal recurrences, we acquired phase data sets (25 slices) every 10 to 15 minutes over the treatment time (60-90 minutes) using gradient echo sequences (echo time = 20 ms), transformed the phase differences to MR temperatures, and fused the color-coded MR-temperature distributions with anatomic T1-weighted MR data sets. We could generate one complete series of MR data sets per patient with satisfactory quality for further analysis. In fat, muscle, water bolus, prostate, bladder, and tumor, we delineated regions of interest (ROI), used the fat ROI for drift correction by transforming these regions to a phase shift zero, and evaluated the MR-temperature frequency distributions. Mean MR temperatures (TMR), maximum TMR, full width half maximum (FWHM), and other descriptors of tumors and normal tissues were noninvasively derived and their dependencies outlined. In 8 of 15 patients, direct temperature measurements in reference points were available. We correlated the tumor MR temperatures with direct measurements, clinical response, and tumor features (volume and location), and found reasonable trends and correlations. Therefore, the mean TMR of the tumor might be useful as a variable to evaluate the quality and effectivity of heat treatments, and consequently as optimization variable. Feasibility of noninvasive MR thermography for regional hyperthermia has been shown and should be further investigated.

    Abstract: Background: Genomic regions that confer susceptibility for bladder cancer have provided important insights into the mechanisms of this disease. Sixteen genomic regions harboring bladder cancer susceptibility loci have been reported to date. To identify additional loci associated with bladder cancer risk, we conducted a meta-analysis including data from previously published genome-wide association studies as well as unpublished data. Methods: Data from 32 studies including 13,790 bladder cancer cases and 343,502 controls of European ancestry were included. Stratified analyses by sex and smoking status, as well as heterogeneity in risk by muscle-invasiveness, were also conducted. We tested for multiplicative and additive interactions between cigarette smoking and susceptibility loci that achieved genome-wide significance. After genotyping, quality control, and imputation log-additive effects were calculated by study/array group using regression models adjusting for age and significant eigenvectors. Results were combined by meta-analysis using a fixed-effects model. Results: We report strengthened or independent signals in several previously published regions at 4p16.3 (TACC3, FGFR3), 5p15.33 (CLPTM1L, TERT) and 11p15.5 (TNNT3, LSP1), as well as nine novel loci. In addition, we observed the first evidence of effect modification by sex at the FGFR3 locus, with a stronger risk observed in women (pmultiplicative-interaction=0.002). Further, we confirmed an interaction between smoking and a susceptibility locus at 8p22 (NAT2), indicating an increased risk of bladder cancer among smokers with the NAT2 slow acetylation genotype/phenotype (pmultiplicative-interaction=0.001). We also identified additional multiplicative, as well as additive, interactions between several novel loci and cigarette smoking status. In addition, we are currently building a risk stratification model using the combined effects of smoking and genetic susceptibility to identify subgroups of individuals at higher and lower absolute risk of bladder cancer. Conclusions: This meta-analysis identified 3 novel loci in previously reported regions and 9 novel bladder cancer susceptibility loci in new regions. These results add to our knowledge of the genetic architecture of bladder cancer. In addition, observed gene-smoking interactions suggest that risk stratification models may have translational implications, informing future disease screening efforts.
