Implication of CD69 + CD103 + tissue-resident-like CD8 + T cells as a potential immunotherapeutic target for cholangiocarcinoma. Liver Int 2021; 41:764-776. [PMID: 33548061 DOI: 10.1111/liv.14814] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 12/21/2020] [Accepted: 01/24/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND The heterogeneous immune landscapes of intrahepatic cholangiocarcinoma (ICC) remain largely unknown. Here we aimed to investigate the implications of tissue-resident memory (TRM)-related features of tumour-infiltrating CD8+ T cells (CD8+ TILs) from ICC patients. METHODS From ICC patients, we obtained blood samples and ICC surgical specimens (n = 33). We performed multicolour flow cytometry, multiplexed immunohistochemistry and RNA sequencing. RESULTS When compared to peripheral CD8+ T cells, the CD8+ TILs included significantly higher proportions of the CD69+ CD103- and CD69+ CD103+ TRM-like subsets (P < .001 for both). Relative to CD69- and CD69+ CD103- cells, the CD69+ CD103+ CD8+ TILs harboured higher levels of T-cell markers representing tumour specificity (ie CD39), proliferation (ie Ki-67) and T-cell activation (ie HLA-DR and CD38) (all P < .001). Moreover, compared to the stroma, the tumour margin and core density each had a significantly higher density of CD103+ CD8+ TILs (P < .001 for both). ICCs with high proportions of CD69+ CD103+ cells displayed higher levels of parameters associated with response to immune checkpoint inhibitors (ICIs)-including number of CD8+ TIL infiltrates (P = .019), PD-L1 expression in the tumour (P = .046) and expression of the T cell-inflamed gene signature (P < .001). ICCs with lower proportions of CD69+ CD103+ CD8+ TILs exhibited significant enrichment of genes related to the Wnt/β-catenin (P < .001) and TGF-β pathways (P = .002). CONCLUSION CD69+ CD103+ TRM-like CD8+ TILs represent prominent tumour-specific immune responses and hold promise as a potential therapeutic target in ICC patients. Differential TRM-related features of ICCs may help develop future immunotherapeutic strategies such as maximizing TRM responses or inhibiting pathways contributing to immune evasion.

Abstract
Leiomyosarcomas account for ~24% of all adult sarcomas, and develop predominantly either in the uterus [uterine leiomyosarcoma (ULMS)] or in deep soft tissue or the retroperitoneum [non-uterine leiomyosarcoma (NULMS)]. Leiomyosarcomas are relatively chemoresistant tumors, and the prognosis of patients with leiomyosarcomas is poor. Cancer-testis (CT) antigens are considered promising immunotherapeutic targets because of their restricted expression in normal tissue, except in the testis. Little is known about the expression of CT antigens in leiomyosarcomas. In the present study, the protein expression of the CT antigens MAGE family member A (MAGEA)1, MAGEA3, MAGEA4, G antigen 7 (GAGE7) and cancer/testis antigen 1 (NY-ESO-1) in ULMS and NULMS were investigated using immunohistochemistry (IHC), and their expression profiles compared. In ULMS and NULMS, positive expression was observed in 11/32 (31%) and 1/31 (3%; MAGEA1), 15/32 (47%) and 5/31 (16%; MAGEA3), 11/32 (34%) and 3/31 (10%; MAGEA4), 23/32 (72%) and 11/31 (35%; GAGE7) and 3/32 (9%) and 0/31 (0%; NY-ESO-1), respectively. The ULMSs demonstrated significantly higher positive expression of MAGEA1 (P=0.0034), MAGEA3 (P=0.0141), MAGEA4 (P=0.0319) and GAGE7 (P=0.0054) compared with the NULMSs. The ULMSs also had significantly higher IHC scores for MAGEA1 (P=0.0023), MAGEA3 (P=0.0474), MAGEA4 (P=0.011), GAGE7 (P=0.0319) and NY-ESO-1 (P=0.0437). The results of the present study support the potential utility of MAGEA1, MAGEA3, MAGEA4 and GAGE7 in ULMS and GAGE7 in NULMS as immunotherapeutic targets.

Abstract
Hepatobiliary and pancreatic cancers along with other gastrointestinal malignancies remain the leading cause of cancer-related deaths worldwide. Strategies developed in the recent years on immunotherapy and cancer vaccines in the setting of primary liver cancer as well as in pancreatic cancer are the scope of this review. Significance of orthotopic and autochthonous animal models which mimic and/or closely reflect human malignancies allowing for a prompt and trustworthy analysis of new therapeutics is underlined. Combinational approaches that on one hand, specifically target a defined cancer-driving pathway, and on the other hand, restore the functions of immune cells, which effector functions are often suppressed by a tumor milieu, are shown to have the strongest perspectives and future directions. Among combinational immunotherapeutic approaches a personalized- and individual cancer case-based therapy is of special importance.

Abstract
Cancer vaccines based on antigens derived from self molecules rather than pathogens have been under basic and clinical investigations for many years. Up until very recently, they had been tested primarily in the setting of metastatic disease with the goal to engage the immune system in slowing down disease progression. Many therapeutic vaccine trials, either investigator initiated or led by pharmaceutical companies, have been completed and many are currently ongoing, following the FDA Guidance on therapeutic cancer vaccines published in 2011. In recent years, the target of cancer vaccines is being shifted to early cancer and even premalignant disease with the goal of preventing cancer. Although some issues addressed in the FDA Guidance on therapeutic vaccines apply to preventive vaccines, many do not. Here, we discuss a set of recommendations for revising the current Guidance to also cover preventive vaccines, or to include in a new Guidance dedicated specifically to vaccines for cancer prevention.

Abstract
BACKGROUND AND AIM Cholangiocarcinomas of different locations differ in growth patterns, symptoms, treatment response, and survival. Still, they are regarded in many studies as a uniform malignancy. Because intra- (iCCA) and extrahepatic (eCCA) cholangiocarcinoma display such differences, we performed a systematic review and meta-analysis to analyze differences in the immunohistochemical profile of these tumors. METHODS In February 2014, we searched the two main medical literature databases MEDLINE and EMBASE. We extracted risk ratios and 95% confidence intervals from the identified studies and performed random-effects model meta-analyses in accordance with PRISMA and REMARK guidelines. RESULTS A total of 54 cohort studies, including 4458 patients and studying 102 individual markers met the inclusion criteria. Of the 57 markers that were evaluated in more than 30 iCCA and eCCA patients, 18 showed a statistically significant difference in expression between iCCA and eCCA. Biomarkers expressed differently between iCCA and eCCA included potential targets of therapy: EGFR, c-erbB-2 and VEGF-A. Several markers showed no statistical difference but large 95% confidence intervals, suggesting insufficient sample size. CONCLUSIONS This systematic review shows differences in marker expression between iCCA and eCCA. Consequently, patients with iCCA and eCCA may benefit from different treatment strategies.

Abstract
Pancreatic cancer is the fourth-leading cause of death in the United States and one of the most aggressive known malignancies. New and innovative advances in treatment are desperately needed. One promising area of investigational treatment for pancreatic cancer involves the use of immunotherapy. The development of immunotherapy for pancreatic cancer has been hampered by difficulty in generating tumor-reactive lymphocytes from resected specimens and by a lack of appropriate target antigens expressed on tumor cells. Innovative strategies have been developed with the use of peripheral blood lymphocytes that are genetically engineered to express T-cell receptors targeting common tumor antigens, including cancer-testis antigens, such as the MAGE-A3 antigen. Cancer-testis antigens pose excellent targets for immunotherapy because they are expressed in cancer and in the testis, an immune-privileged site, but have limited expression in normal tissue. An additional advantage in targeting cancer-testis antigens for immunotherapy is that their expression can be selectively up-regulated in tumor cells via epigenetic regulation with chromatin remodeling agents. Current interest in targeting cancer-testis antigens in pancreatic cancer is well-founded because cancer-testis antigens have been shown to be expressed in pancreatic cancer as potential targets for therapy. In our studies, we validated the expression pattern of cancer-testis antigens in resected specimens of pancreatic cancer and tested the hypothesis that treatment of pancreatic cancer cells with chromatin remodeling agents would render them more sensitive to antigen-specific T lymphocytes. We focused predominately on the MAGE-A3 antigen because it is highly expressed in pancreatic cancer, and several immunotherapeutic strategies are in clinical trials targeting this specific antigen. The results of these studies have important translational implications and provide the rationale for combined treatment with chromatin remodeling agents and immunotherapeutic approaches for pancreatic cancer.

Abstract
Background Cancer-testis antigens (CTAs) are suitable targets for cancer-specific immunotherapy. The aim of the study is to investigate the expression of CTAs in intrahepatic cholagiocarcinoma (IHCC) and evaluate their potential therapeutic values. Methods Eighty-nine IHCC patients were retrospectively assessed for their expression of CTAs and HLA Class I by immunohistochemistry using the following antibodies: MA454 recognizing MAGE-A1, 57B recognizing multiple MAGE-A (MAGE-A3/A4), E978 recognizing NY-ESO-1, and EMR8-5 recognizing HLA class I. The clinicopathological and prognostic significance of individual CTA markers and their combination were further evaluated. Results The expression rates of MAGE-A1, MAGE-A3/4 and NY-ESO-1 were 29.2%, 27.0% and 22.5%, respectively. The concomitant expression of CTAs and HLA class I antigen was observed in 33.7% of the IHCC tumors. We found that positive MAGE-3/4 expression correlated with larger tumor size (≥ 5 cm), tumor recurrence and poor prognosis. Moreover, we identified 52 cases (58.4%) of IHCC patients with at least one CTA marker expression, and this subgroup displayed a higher frequency of larger tumor size and a shorter survival than the other cases. Furthermore, expression of at least one CTA marker was also an independent prognostic factor in patients with IHCC. Conclusion Our data suggest that specific immunotherapy targeted CTAs might be a novel treatment option for IHCC patients.

Abstract
P-cadherin (CDH3) and CD24 are cell adhesion molecules that control morphogenic processes, cell motility, and invasive growth of tumor cells. The aim of our study was to investigate P-cadherin and CD24 expression in carcinomas and dysplastic lesions of the biliary tract and to evaluate the potential diagnostic usefulness of these cell adhesion molecules. Using immunohistochemistry on tissue microarrays, we analyzed P-cadherin, CD24, and p53 expression in 117 carcinomas of the biliary tract (19 intrahepatic cholangiocarcinomas, 59 extrahepatic cholangiocarcinomas, and 39 gallbladder carcinomas) and correlated our findings with clinicopathologic parameters. We found P-cadherin positivity in 37% of intrahepatic cholangiocarcinomas, 73% of extrahepatic cholangiocarcinomas, and 64% of gallbladder carcinomas, respectively. CD24 reactivity was observed in 21% of intrahepatic cholangiocarcinomas, 58% of extrahepatic cholangiocarcinomas, and 42% of gallbladder carcinomas. Nuclear p53 expression was found in 37% of intrahepatic cholangiocarcinomas, 46% of extrahepatic cholangiocarcinomas, and 45% of gallbladder carcinomas. We also studied P-cadherin, CD24, and p53 expression in normal (n = 30), inflamed (n = 22), and dysplastic (n = 21) biliary epithelium of extrahepatic bile ducts. Dysplastic biliary epithelium was positive for P-cadherin in 91%, for CD24 in 71%, and for p53 in 24% of lesions, respectively. In contrast, normal and inflamed epithelia were negative for all 3 proteins. We conclude that P-cadherin and CD24 are expressed in carcinomas of the biliary tract with high frequency and at an early stage of carcinogenesis. Therefore, they may be useful markers for early detection and as targets for therapy of cholangiocarcinoma.

Abstract
Biliary intraepithelial neoplasia (BilIN) is the premalignant lesion of extrahepatic cholangiocarcinoma (EHC), and there are no published data regarding epigenetic changes throughout disease progression from normal biliary epithelia to BilIN to EHC. The objective of this study was to identify the occurrence of CpG island hypermethylation and repetitive DNA hypomethylation in BilIN. A total of 50 EHCs, 31 BilINs, and 31 normal cystic duct samples were analyzed for their methylation status in seven genes and two repetitive DNA elements. The number of methylated genes increased with disease progression (normal bile duct, 0.6; BilIN, 2.0; EHC, 3.6; P < 0.001). The methylation level of examined genes was significantly higher in BilIN than in normal samples (TMEFF2, HOXA1, NEUROG1, and RUNX3, P < 0.05) and in EHC than in BilIN samples (TMEFF2, HOXA1, NEUROG1, RUNX3, RASSF1A, and APC, P < 0.05). Long interspersed nucleotide element-1 (LINE-1) and juxtacentromeric satellite 2 (SAT2) methylation levels were markedly lower in EHC than in normal duct and BilIN samples, and BilIN samples showed a decrease of SAT2 methylation levels but no decrease of LINE-1 methylation levels compared to normal samples. These findings suggest that most of cancer-specific CpG island hypermethylation occur in the stage of BilIN and that CpG island hypermethylation seems to occur earlier than repetitive DNA element hypomethylation.

Abstract
Cancer testis (CT) antigens are attractive targets for immunotherapy in cancer patients. Immunohistochemistry was used to study the expression of the CT antigens MAGE-C2/CT-10, MAGE-C1/CT-7, GAGE, MAGE-A4 and NY-ESO-1 in 146 hepatocellular carcinomas, 13 intrahepatic cholangiocarcinomas, 37 extrahepatic cholangiocarcinomas and 32 gallbladder carcinomas. Immunopositivity was correlated with clinicopathological parameters, MHC Class 1 expression, intratumoral CD4+, CD8+ and FOXP3+ T cells and CD163+ antigen-presenting cells. Of the 146 hepatocellular carcinomas, 34% were positive for MAGE-C2/CT-10, 12% for MAGE-C1/CT-7, 11% for GAGE and 2% for NY-ESO-1, respectively. MHC Class 1 coexpression was identified in almost all CT antigen-positive tumors. The number of intratumoral FOXP3+ regulatory T cells was increased in CT antigen-positive hepatocellular carcinomas (p<0.004), suggesting inhibition of immune response in such tumors. Furthermore, MAGE-C1/CT-7 and GAGE positivity was correlated with reduced overall survival in patients with hepatocellular carcinoma (p=0.03 and 0.01, respectively). Four (13%) gallbladder carcinomas stained positive for MAGE-C2/CT-10, of which 1 tumor (3%) was also positive for NY-ESO-1 and GAGE. CT antigens were not expressed in intra- and extrahepatic cholangiocarcinomas. Our results suggest that MAGE-C2/CT-10 may be a good candidate for peptide vaccination in patients with hepatocellular carcinoma.

Abstract
Select groups of premalignant oral lesions carry a high risk of development of secondary premalignant lesions and oral squamous cell carcinoma (OSCC). The goal of the present study was to determine the feasibility of using premalignant lesion-pulsed dendritic cells as a treatment option to prevent development of secondary lesions and development of OSCC. Mice that were treated with the carcinogen 4-nitroquinoline-1-oxide (4NQO) developed premalignant oral lesions and, subsequently, OSCC. Immunohistochemical analyses showed that these 4NQO-induced lesions and OSCC both overexpressed the tumor antigens epidermal growth factor receptor, RAGE and, to a lesser extent, MUC1. Because there was shared overexpression of tumor antigens on premalignant oral lesions and OSCC, dendritic cells pulsed with lysates of 4NQO-induced premalignant lesion cells were tested in vitro and in vivo for their capacity to stimulate T-cell reactivity to premalignant lesion cells and to OSCC. Spleen cells that were sensitized during coculture or in vivo with premalignant lesion-pulsed dendritic cells were cytolytic toward both premalignant lesion cells and OSCC, and secreted increased levels of interferon -gamma in response to challenge with premalignant lesion cells or OSCC as compared with spleen cells that were sensitized with keratinocyte-pulsed dendritic cells. Levels of CD8+ Tcells and interferon-gamma release were also increased in lesions of mice that were vaccinated with premalignant lesion-pulsed dendritic cells. The mice that were vaccinated against premalignant lesions were also more resistant to OSCC challenge.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is an aggressive malignancy, and despite advances in treatments, the 5-year survival has remained at less than 50%. One treatment strategy is to focus on patients with premalignant oral lesions that carry a high-risk for developing recurrent premalignant lesions and HNSCC disease. As an initial attempt to determine if immune therapy has the potential to be protective in these patients, studies determined if premalignant lesions express tumor antigens that have previously been shown to be expressed on HNSCC. Immunohistochemical analyses showed prominent expression of epidermal growth factor receptor in premalignant lesions, even in lesions with mild dysplasia. MUC-1 and carcinoembryonic antigen were expressed in most patient samples, while NY-ESO-1 was less frequently expressed. Each of these antigens was expressed on HNSCC. This provided the rationale for determining if premalignant oral lesions could be used to stimulate autologous peripheral blood mononuclear leukocytes (PBML) to react against heterologous premalignant lesions and HNSCC. Following sensitization with autologous premalignant lesions, PBML responded to a challenge with either heterologous premalignant oral lesion cells or HNSCC by releasing IFN-gamma. In addition, sensitization with autologous premalignant lesion lysates generated cytolytic activity by both PBML and T cells against allogeneic premalignant lesion cells and HNSCC. These studies show the feasibility of using premalignant oral lesions to stimulate immune reactivity against both premalignant oral lesions as well as HNSCC.

Abstract
INTRODUCTION Distant metastases of solid tumors are usually associated with fatal outcome. Disseminated cancer cells are considered early indicators of metastasis. Their sensitive detection and quantification would be a valuable tool for staging of disease and as guidance for therapeutic decisions. EXPERIMENTAL DESIGN We established a highly sensitive and quantitative multimarker real-time RT-PCR assay for amplification of cancer-related genes MAGE-A1, -A2, -A3/6, -A4, -A10 and -A12 using SYBR green I to detect one single tumor cell in 2 mL of blood or bone marrow. The feasibility of the assay was tested in a large cohort of 177 patients with locally confined prostate carcinoma. RESULTS Analysis revealed frequent MAGE expression in venous blood and bilateral bone marrow samples (25.5% of all cases) and yielded the first quantitative profile of MAGE expression with a broad range of transcript concentrations for individual markers in the minimal systemic tumor load of patients with localized cancer. CONCLUSIONS Rare transcripts of different MAGE-A genes can be quantified in clinical samples of cancer patients by a sensitive multimarker real-time RT-PCR. Because of frequent expression of MAGE genes in various types of cancer the multimarker MAGE real-time RT-PCR may be generally useful for detection, quantification and characterization of the individual disseminated tumor load in cancer patients.

Abstract
BACKGROUND Cancer-testis antigens (CTA), such as MAGE, are selectively expressed in various types of human neoplasms but not in normal tissues other than testis. This characteristic feature of CTA makes them promising antigens for cancer-specific immunotherapy. METHODS We investigated the expression of five genes, including MAGE-1, MAGE-3, NY-ESO-1, SCP-1, and SSX-4, in 20 surgical samples of intrahepatic cholangiocarcinomas (IHCC) using reverse transcription-polymerase chain reaction. To visualize the localization of MAGE proteins, we performed immunohistochemical studies. Furthermore, the correlation between the CTA expression and DNA methylation status was studied in three bile duct cancer cell lines. RESULTS Expression of MAGE-1, MAGE-3, NY-ESO-1, SCP-1, and SSX-4 was recognized in 4, 4, 2, 6, and 3 of all 20 cases, respectively. In contrast, the expressions of five genes were not recognized at all in the corresponding normal tissues. In 10 cases (50%), the tumors expressed at least one of the five CTA. An immunohistochemical analysis of MAGE proteins demonstrated homogenous or focal distributions in cytoplasm of the IHCC. Using a demethylating agent, MAGE-1, NY-ESO-1, SCP-1, and SSX-4 were induced in two of three cell lines, whereas MAGE-3 was not. CONCLUSIONS Half of the tumor tissues of IHCC expressed at least one of the CTA. Some of the patients with IHCC, therefore, should be candidates for potentially useful cancer-specific immunotherapy.
