Abstract
The relationship between cancer stem cells (CSCs) in oral squamous cell carcinoma (OSCC) and programmed cell death ligand 1 (PD-L1)/programmed cell death 1 (PD-1) remains unclear. Therefore, the present study aimed to clarify the association between the CD44v3high/CD24low immunophenotype of CSCs in OSCC and PD-L1/PD-1 co-expression, and to assess the prognostic effect of CSCs in terms of immune checkpoint molecules. Formalin-fixed, paraffin-embedded tissue samples and clinicopathological data from 168 patients with OSCC were retrospectively retrieved. Immunohistochemical staining and reverse transcription quantitative polymerase chain reaction were applied to a tissue microarray of the invasive front of each case. Semi-automated cell counting was used to assess CD44v3, CD24, PD-L1 and PD-1 expression by immunohistochemistry (IHC) using a digital image analysis program. Associations between immunological markers and clinicopathological variables were estimated. Patients with the CSC immunophenotype CD44v3high/CD24low, and patients with a high PD-L1/PD-1-positive cell density in the tumor parenchyma and stroma had significantly lower survival rates. Furthermore, patients with the CSC immunophenotype (CD44v3high/CD24low) and high PD-L1/PD-1 co-expression had even lower survival rates (P<0.01, log-rank test). Notably, there was a positive correlation between CD44v3 and PD-L1 expression (τ=0.1096, P=0.0366, Kendall rank correlation coefficient) and a negative correlation between CD24 and PD-1 expression (τ=-0.1387, P=0.0089, Kendall rank correlation coefficient). Additionally, the high CD44v3 expression group, as determined by IHC, exhibited significantly decreased expression of U2 small nuclear RNA auxiliary factor 1 (U2AF1) at the mRNA level compared with that in the low CD44v3 expression group (P<0.001, Mann-Whitney U test), and U2AF1 and PD-L1 mRNA expression exhibited a significant negative correlation (τ=-0.3948, P<0.001, Kendall rank correlation coefficient). In conclusion, CSCs in OSCC may evade host immune mechanisms and maintain CSC stemness via PD-L1/PD-1 co-expression, resulting in unfavorable clinical outcomes.

Abstract
Small cell carcinoma is rare in salivary glands and has recently been termed small cell neuroendocrine carcinoma. We herein describe an uncommon example arising in the parotid gland. The patient was a 75 yearold Japanese male who had swelling in the right parotid area. He underwent a superficial lobectomy and, after a histological diagnosis was made, a total parotidectomy. Histologically, the tumor had a thick hyalinized capsule that was incomplete, beyond which the tumor invaded into the surrounding parotid parenchyma. The tumor consisted of typical small basophilic cells intermingled with bland clear cells, between which a gradual transition was observed both inside and outside the capsule. Small basophilic cells were immunoreactive for chromograninA as well as synaptophysin, while clear cells were positive for S100 protein. The Ki-67 labeling rate reached 30-40% at the high points of small basophilic cells, but clear cells were minimally labelled. The present case was considered a dedifferentiated carcinoma of the parotid gland, possibly with acinic cell carcinoma as a precursor. This tumor could also be considered a "mixed exocrine-endocrine carcinoma," which may explain the histogenesis of neuroendocrine carcinomas in non-endocrine organs that are not included in the diffuse (dispersed) neuroendocrine system, such as the parotid gland.

Abstract
BACKGROUND The presence of cachexia negatively impacts the prognosis of patients with cancer. However, the mechanisms behind the development of cachexia and its prognostic impact on immunotherapy efficacy are not fully understood. MATERIALS AND METHODS We retrospectively screened patients with advanced or recurrent non-small cell lung cancer (NSCLC) who received PD-1/PD-L1 inhibitor monotherapy. Among 183 patients, pre-treatment plasma samples were available from 100 patients. We defined cancer cachexia as weight loss of at least 5% during the past 6 months or weight loss of at least 2% and BMI <20. We analyzed 75 soluble immune mediators in pre-treatment plasma samples to explore the possible mechanisms behind the development of cancer cachexia. We also investigated whether cancer cachexia affects prognosis. RESULTS Among 100 patients, 35 had cancer cachexia. Logistic regression analysis identified ghrelin, c-reactive protein (CRP), pentraxin-3 (PTX-3), and osteopontin (OPN) as factors associated with cachexia. Patients with cachexia had worse progression-free survival (PFS) and overall survival (OS), although we did not detect statistically significant differences. Analyzing the soluble immune mediators associated with cachexia, the combination of cachexia and PTX-3 or OPN expression levels was predictive for PFS and the combination of cachexia and CRP or OPN expression levels was predictive for OS. CONCLUSIONS Pre-treatment ghrelin, CRP, PTX-3, and OPN may be associated with cachexia. Among patients with NSCLC who received PD-1/L1 inhibitor monotherapy, those with cachexia had worse survival than those without cachexia. Larger studies will be required to confirm our data and better understand the mechanisms behind the development of cachexia.

Abstract
Introduction Expression of the NTRK gene is rare in solid tumors but is highly prevalent in salivary gland secretory carcinomas. Here, we report a case of a complete response to entrectinib in a patient with NTRK fusion gene-positive parotid carcinoma. Case description The patient was a 44-year-old man who underwent total left parotidectomy and left cervical lymph node dissection for a left parotid tumor at 24 years of age. The histopathological diagnosis was mammary analog secretory carcinoma. Postoperatively, the patient received only radiation therapy. Sixteen years after the surgery, the patient became aware of a mass in the left parotid region. A close examination revealed local recurrence and multiple cervical lymph node metastases. S-1 monotherapy was started as chemotherapy but was discontinued 3 years later because of disease progression. As there was no standard treatment, a comprehensive genomic profiling test using a next-generation sequencer was performed, and the ETV6-NTRK3 fusion gene was identified. Entrectinib, an NTRK inhibitor, was immediately administered at a dose of 600 mg/day. The local recurrence rapidly shrank grossly from the beginning of treatment, and a complete response was observed 6 months later. However, creatinine levels exhibited an increase at week 68 of treatment; consequently, entrectinib dosage was lowered to 400 mg/day, leading to an immediate improvement in creatinine levels. Entrectinib was associated with additional side effects, including dysgeusia, fatigue, dizziness, and weight gain, all of which were also alleviated by the reduction in entrectinib dose. Thirty months after treatment initiation, the patient maintained a complete response and continued to receive entrectinib. Conclusion The NTRK fusion gene should always be checked in the presence of salivary gland secretory carcinoma.

Abstract
BACKGROUND/AIM Detection of pancreatic cancer using small samples of the pancreas obtained by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) remains a challenge. The purpose of this study was to investigate whether the detection of KRAS mutations in cell-free DNA (cfDNA) extracted from supernatants of liquid-based fixed cytology (LBC) specimens obtained using EUS-FNA in solid pancreatic cancer can be an auxiliary test for differential diagnosis. The purpose of this study was to investigate whether the detection of KRAS mutations in cell-free DNA (cfDNA) extracted from supernatants of liquid-based fixed cytology (LBC) specimens obtained using EUS-FNA in solid pancreatic cancer can be an auxiliary test for differential diagnosis. PATIENTS AND METHODS This was a single-institution cohort study that included 50 patients with pancreatic lesions. cfDNA was isolated from the supernatant of fixed LBC samples, and KRAS mutation status was compared between cfDNA samples and FFPE small fragment tissues. RESULTS Of the 50 cfDNA samples, 84% (42/50) were valid. KRAS mutations were detected in 57.1% (24/42) of the 42 valid samples. The sensitivity, specificity, and accuracy of KRAS mutation detection using cfDNA samples in the pancreatic lesions were 63.2% (24/38), 100.0% (4/4), and 66.7% (28/42), respectively. KRAS mutation status between FFPE small tissues and cfDNA samples were comparable. CONCLUSION Gene mutation analysis using cfDNA from the supernatant of fixed LBC samples is an effective ancillary diagnostic tool for pancreatic cancer.

Abstract
Intracholecystic papillary neoplasm (ICPN) is a non-invasive epithelial tumor that presents as a grossly identifiable mass arising in the mucosa and protruding into the lumen. ICPN is associated with invasive carcinoma. There are few studies on the clinicopathological features of ICPN, including that with invasive carcinoma. We evaluated the clinicopathological characteristics of 42 ICPNs and 41 conventional gallbladder adenocarcinomas (cGBAs). Subserosa or deeper (≥ss) invasion was significantly lower in ICPN (61.9%) than that in cGBA (90.2%) (P=0.004). Cox regression analysis revealed that lymph node metastasis (hazard ratio [HR] [95% confidence interval (CI)]: 2.610 [1.131, 6.024], P=0.025) and positive margin (HR [95% CI]: 5.143 [2.113, 12.516], P<0.001), but not ≥ss invasion (HR [95% CI]: 1.541 [0.479, 4.959], P=0.469), were independent prognostic factors. In addition, there was a significant interaction between histological type and lymph node metastasis (HR [95% CI]: 0.191 [0.042, 0.983], P=0.033). In cGBA, the presence or absence of lymph node metastasis did not affect prognosis; however, ICPN without lymph node metastasis had better prognosis. Therefore, the histological classification of ICPN and cGBA and the pathological evaluation of lymph node metastasis in ICPN are crucial for determining prognosis.

Abstract
BACKGROUND The presence of cachexia in cancer patients negatively affects the quality of life and survival. However, the impact of cachexia on immunotherapy, such as PD-1/L1 inhibitors, is not fully understood. Therefore, we examined whether cancer cachexia affects the prognosis of patients with non-small cell lung cancer (NSCLC) treated with PD-1/PD-L1 inhibitors. METHODS We retrospectively screened patients with pathologically confirmed advanced or recurrent NSCLC who were treated with PD-1/PD-L1 monotherapy at Kurume University Hospital. We defined cancer cachexia as weight loss of at least 5% during the past 6 months or any degree of weight loss more than 2% and BMI <20. RESULTS Among 182 patients, 74 had cancer cachexia. The presence of cachexia was significantly associated with females, poor performance status (PS), never-smokers, and driver mutations. Multivariate analysis revealed that poor PS and being a smoker were associated with the presence of cachexia. Patients with cancer cachexia had significantly shorter progression-free survival (PFS) and overall survival (OS). In the multivariate analysis, PS and sex were significantly correlated with PFS, whereas PS and cachexia were significantly correlated with OS. Subanalysis revealed that patients in the PS0/without cachexia group had longer PFS and OS than those in the cachexia or PS1-3 group. CONCLUSIONS In NSCLC patients, cachexia was associated with a worse prognosis, irrespective of tumor PD-L1 expression, indicating that cachexia is a predictive factor for NSCLC patients receiving immune checkpoint inhibitors.

Abstract
BACKGROUND Radiotherapy (RT) destroys cancer cells and activates the immune system while suppressing the immunity of tumor-associated tissues, including the tumor microenvironment (TME). However, to date, no anti-tumor therapeutic strategy that uses these immune mechanisms has been established. This study investigated changes in the immunity of the TME during standard radical RT for cervical cancer combined with external beam RT and brachytherapy and determined whether these changes affect prognosis. METHODS Twenty-six patients who had completed radical RT for cervical cancer were categorized into the following two groups according to whether the cancer recurred and/or metastasized within 2 years after the start of treatment: treatment failure (n = 14) and treatment success (n = 12). We assessed the expression of programmed death 1, programmed death ligand 1 (PD-L1), cluster of differentiation (CD) 8, CD68, CD163, Forkhead box protein P3, and hypoxia-inducible factor-1α in the TME of cervical tissues collected periodically during treatment and evaluated the difference in expression rates of each marker between the success and failure groups and assessed its effect on prognosis. RESULTS The expression levels of PD-L1 and CD163 in the TME in the treatment success group were lower than those in the treatment failure group at the midpoint during brachytherapy (p < 0.01 and p = 0.08, respectively), and the 2-year progression-free-survival (PFS) rate depended on the expression levels of PD-L1 and CD163 (p = 0.04 and p = 0.02, respectively). CONCLUSIONS The expression rates of CD163 and PD-L1 in the TME during brachytherapy were related to treatment response and the 2-year PFS. This study may increase our understanding of tumor-associated immunity in the TME and aid in the development of therapies targeting PD-L1 or M2 macrophages in the TME in conjunction with RT, especially brachytherapy, for cervical cancer patients.

Abstract
Rapid advances are being made in cancer drug therapy. Since molecularly targeted therapy has been introduced, personalized medicine is being practiced, pathological tissue from malignant tumors obtained during routine practice is frequently used for genomic testing. Whereas cytological specimens fixed mainly in alcohol are considered to be more advantageous in terms of preservation of the nucleic acid quality and quantity. This article is aimed to share the information for the proper handling of cytological specimens in practice for genomic medicine based on the findings established in "Guidelines for Handling of Cytological Specimens in Cancer Genomic Medicine (in Japanese)" published by the Japanese Society of Clinical Cytology in 2021. The three-part practical guidelines are based on empirical data analyses; Part 1 describes general remarks on the use of cytological specimens in cancer genomic medicine, then Part 2 describes proper handling of cytological specimens, and Part 3 describes the empirical data related to handling of cytological specimens. The guidelines indicated proper handling of specimens in each fixation, preparation, and evaluation.

Abstract
BACKGROUND/AIM The cumulative cancerous rate of colitis-associated cancer (CAC) has increased exponentially in patients with ulcerative colitis (UC). We have investigated the factors involved in the carcinogenic processes of CAC among UC patients. PATIENTS AND METHODS A total of 42 UC patients who underwent surgical treatments between January 2001 and December 2010 at Kurume University Hospital (Fukuoka, Japan) were enrolled. We conducted this study using 3 cases of CAC out of 42 UC cases and 1 case of colorectal cancer. cDNA microarray analyses were performed using normal, inflamed, and cancerous tissues from surgical CAC specimens and protein expression was confirmed by immunohistochemical analyses. RESULTS cDNA microarray revealed 32 genes that were dominantly expressed in tumorous regions of CAC. Gene ontology analysis revealed that these genes were involved in inflammatory responses and cytokine-cytokine receptor interactions. Chitinase 3-like1 (CHI3L1), carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6), and Claudin-2 (CLND2) were selected from CAC-related genes as candidate molecules. Immunostaining revealed strong expression of each protein in cancerous regions. CONCLUSION In this study, we identified CAC-related genes and found that CHI3L1, CEACAM6, and CLND2 were expressed in patient samples. All the above genes were associated with adherent invasive Escherichia coli (AIEC), which suggested that these molecules are likely involved in AIEC infection. Further analyses would be required to reveal unknown mechanisms of CAC-related genes in the tumor microenvironment.

Abstract
BACKGROUND/AIM Sulphite oxidase (SUOX) is a metalloenzyme that catalyses ATP synthesis via oxidative phosphorylation in the mitochondria. Although SUOX has been reported to affect the invasiveness and differentiation of cancer cells, its clinicopathological significance in pancreatic adenocarcinoma (PDAC) remains unclear. In this study, we investigated the utility of SUOX expression as a prognostic factor in PDAC. PATIENTS AND METHODS This study included 56 patients with PDAC who underwent pancreatic resection at the Kurume University Hospital between 2014 and 2018. SUOX immunohistochemistry was evaluated using tissue microarray specimens from patients. Patients were classified into a high SUOX expression group (≥10% of cells stained) or a low SUOX expression group (<10% of cells stained), and the associations of SUOX with clinicopathological characteristics and survival were analysed. Statistical analysis was performed using Cox regression analysis, the Kaplan-Meier method, and log-rank test. RESULTS SUOX was expressed in the cytoplasm of normal pancreatic ductal epithelium, pancreatic acinar cells, and islets of Langerhans. Although we did not find any significant correlation between SUOX expression and clinicopathological factors, SUOX was identified as an independent prognostic factor based on univariate and multivariate analyses. Pathological stage was also an independent prognostic factor. The high SUOX expression group showed a significantly poorer prognosis than the low SUOX expression group (p=0.018). CONCLUSION SUOX-mediated mitochondrial metabolism in PDAC may be a factor influencing prognosis and SUOX may be a potential novel prognostic biomarker.

Abstract
Osimertinib, a third-generation EGFR-TKI, has nowadays been applied to non-small cell lung cancer harboring activated EGFR mutation with or without T790M, but ultimately develop resistance to this drug. Here we report a novel mechanism of acquired resistance to osimertinib and the reversal of which could improve the clinical outcomes. In osimertinib-resistant lung cancer cell lines harboring T790M mutation that we established, expression of multiple EGFR family proteins and MET was markedly reduced, whereas expression of AXL, CDCP1 and SRC was augmented along with activation of AKT. Surprisingly, AXL or CDCP1 expression was induced by osimertinib in a time-dependent manner up to 3 months. Silencing of CDCP1 or AXL restored the sensitivity to osimertinib with reduced activation of SRC and AKT. Furthermore, silencing of both CDCP1 and AXL increased the sensitivity to osimertinib. Either silencing of SRC or dasatinib, a SRC family kinase (SFK) inhibitor, suppressed AKT phosphorylation and cell growth. Increased expression of AXL and CDCP1 was observed in refractory tumor samples from patients with lung cancer treated with osimertinib. Together, this study suggests that AXL/SFK/AKT and CDCP1/SFK/AKT signaling pathways play some roles in acquired osimertinib resistance of non-small cell lung cancer.

Abstract
Background Amino acid metabolism is essential for tumor cell proliferation and regulation of immune cell function. However, the clinical significance of free amino acids (plasma-free amino acids (PFAAs)) and tryptophan-related metabolites in plasma has not been fully understood in patients with non-small cell lung cancer (NSCLC) who receive immune checkpoint inhibitors. Methods We conducted a single cohort observational study. Peripheral blood samples were collected from 53 patients with NSCLC before treatment with PD-1 (Programmed cell death-1) inhibitors. The plasma concentrations of 21 PFAAs, 14 metabolites, and neopterin were measured by liquid chromatography–mass spectrometry. Using Cox hazard analysis with these variables, a multivariate model was established to stratify patient overall survival (OS). Gene expression in peripheral blood mononuclear cells (PBMCs) was compared between the high-risk and low-risk patients by this multivariate model. Results On Cox proportional hazard analysis, higher concentrations of seven PFAAs (glycine, histidine, threonine, alanine, citrulline, arginine, and tryptophan) as well as lower concentrations of three metabolites (3h-kynurenine, anthranilic acid, and quinolinic acid) and neopterin in plasma were significantly correlated with better OS (p<0.05). In particular, the multivariate model, composed of a combination of serine, glycine, arginine, and quinolinic acid, could most efficiently stratify patient OS (concordance index=0.775, HR=3.23, 95% CI 2.04 to 5.26). From the transcriptome analysis in PBMCs, this multivariate model was significantly correlated with the gene signatures related to immune responses, such as CD8 T-cell activation/proliferation and proinflammatory immune responses, and 12 amino acid-related genes were differentially expressed between the high-risk and low-risk groups. Conclusions The multivariate model with PFAAs and metabolites in plasma might be useful for stratifying patients who will benefit from PD-1 inhibitors.

Abstract
Background Hepatocellular carcinoma (HCC) is a highly lethal cancer and the second leading cause of cancer-related deaths worldwide. As demonstrated in other solid neoplasms and HCC, infiltrating CD8+ T cells seem to be related to a better prognosis, but the mechanisms affecting the immune landscape in HCC are still mostly unknown. Necroptosis is a programmed, caspase-independent cell death that, unlike apoptosis, evokes immune response by releasing damage-associated molecular factors. However, in HCC, the relationship between the necroptotic machinery and the tumor-infiltrating lymphocytes has not been fully investigated so far. Methods We investigated the association between the main necroptosis-related genes, that is, RIPK1, RIPK3, MLKL-p, and CD3+/CD8+ tumor-infiltrating T cell by RNA-seq data analysis in 371 patients with primary HCC from The Cancer Genome Atlas and then by immunohistochemistry in two independent cohorts of HCC patients from Italy (82) and Japan (86). Results Our findings highlighted the immunogenetic role of necroptosis and its potential prognostic role in HCC: RIPK1, RIPK3 and MLKL-p were found significantly associated with intratumoral CD3+ and CD8+ T cells. In addition, multivariate survival analysis showed that the expression of RIPK1, RIPK3 and MLKL-p was associated with better overall survival in the two independent cohorts. Conclusions Our results confirmed the immunogenetic properties of necroptosis (NCP) in human HCC, showing that tumor-infiltrating lymphocytes (TILs) and, specifically, CD8+ T cells accumulate in tumors with higher expression of the necroptosis-related genes. These results suggest the importance of further studies to better assess the specific composition, as well as the functional features of the immune environment associated with a necroptotic signature in order to explore new possible diagnostic and immunotherapeutic scenarios.

Abstract
Background Secretory carcinoma (SC) of the salivary gland is a recently described malignant tumor harboring characteristic ETV6-NTRK3 gene fusion. SC generally has a favorable clinical course, and is currently regarded as a low-grade carcinoma. However, a small subset of SCs demonstrates aggressive clinical features with histologically high-grade transformed morphology, the molecular pathogenesis of which has not yet been elucidated. In this study, we performed a clinicopathological and molecular genetic study of patients with SC of the head and neck displaying various clinical characteristics to investigate the differences of pathological and molecular genetics between low-grade and high-grade components of SC. Case presentation Three cases with SC of the head and neck, including a conventional low-grade SC and two high-grade transformed SCs are described. High-grade transformed SCs with histological features such as nuclear polymorphism, distinctive nucleoli and increased mitotic activity developed locoregional recurrence and distant metastasis. Immunohistochemical analysis revealed that low- and high-grade components showed different expression patterns for S-100 protein and mammaglobin, whereas all examined components were positive for p-STAT5. p53-positive cell population was markedly higher in one case with high-grade transformed SC. The proliferative activity of high-grade components was markedly increased, with the Ki-67 labeling index ranging up to 30–32%. A fluorescence in situ hybridization study with an ETV6 (12p13) break apart probe revealed split signals in the nuclei in all 3 cases. A targeted next-generation sequencing-based fusion assay demonstrated that all 6 clinical samples from the 3 patients showed the presence of the ETV6-NTRK3 fusion transcripts. One patient with high-grade transformed SC showed a dramatic clinical response to the pan-TRK inhibitor, entrectinib, for the treatment of locoregional recurrence and pulmonary metastasis. Conclusions High-grade transformed SC showed aggressive clinical and pathological features with increased Ki-67 labeling index. Molecular genetic study of gene rearrangement appears to be beneficial treatment as the presence of ETV6-NTRK3 translocation may represent a therapeutic target in SC, particularly the high-grade transformed type.

Abstract
Background The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a risk‐stratification reporting system that was introduced in 2018. The objective of this multi‐institutional study was to evaluate the utility of the MSRSGC in Japan. Methods In total, 1608 fine‐needle aspiration samples with matching histologic diagnoses were retrieved from 12 large institutions in Japan. The diagnostic categories of the MSRSGC were assigned prospectively or retrospectively, and the results were compared with the histologic diagnoses. Results The cases were classified as follows: nondiagnostic, 18.1%; non‐neoplastic, 4.1%; atypia of undetermined significance, 11.5%; neoplasm‐benign, 43.7%; salivary gland neoplasm of uncertain malignant potential, 9.6%; suspicious for malignancy, 3.6%; and malignant, 9.4%. The risk of neoplasm and the risk of malignancy in each MSRSGC category were as follows: nondiagnostic, 72.9% and 13.4%, respectively; non‐neoplastic, 15.2% and 9.1%, respectively; atypia of undetermined significance, 77.9% and 24.9%, respectively; neoplasm‐benign, 99% and 1.8%, respectively; salivary gland neoplasm of uncertain malignant potential, 94.8% and 37%, respectively; suspicious for malignancy, 100% and 89.7%, respectively; and malignant, 100% and 99.3%, respectively. The accuracy of the MSRSGC for diagnosing neoplasms was 97.8%, and its accuracy for diagnosing malignancy was 97.3%. Institutions that used Romanowsky‐stained preparations had lower nondiagnostic rates and lower risks of neoplasm and malignancy in the non‐neoplastic category. Conclusions The MSRSGC is useful for risk stratification and quality control. Widespread use of the MSRSGC would improve the accuracy of salivary gland cytology and lead to better patient care in Japan. This is the first multi‐institutional study of a large‐scale application of the Milan System for Reporting Salivary Gland Cytopathology in Japan. It demonstrates the usefulness of the Milan system in the diagnosis of salivary gland lesions and for the quality control of salivary gland cytology results.

Abstract
The tumor immune response is dependent on the interaction between tumor cells and the T-cell subset expressing the T-cell receptor (TCR) repertoire that infiltrates into the tumor microenvironment. The present study explored the diversity and shared TCR repertoires expressed on the surface of locoregional T cells and identified the T lymphocyte subsets infiltrating into esophageal squamous cell carcinoma (ESCC), in order to provide insight into the efficiency of immunotherapy and the development of a novel immune-oriented therapeutic strategy. A total of 53 patients with ESCC were enrolled in the present study, and immunohistochemical analysis of CD3, CD8, CD45RO, FOXP3, CD274, HLA class I and AE1/AE3 was performed. Digital pathological assessment was performed to evaluate the expression level of each marker. The clinicopathological significance of the immuno relation high (IR-Hi) group was assessed. Adaptor ligation PCR and next-generation sequencing were performed to explore the diversity of the TCR repertoire and to investigate the shared TCR repertoire in the IR-Hi group. Repertoire dissimilarity index (RDI) analysis was performed to assess the diversity of TCR, and the existence of shared TCRα and TCRβ was also investigated. Further stratification was performed according to the expression of markers of different T-cell subsets. Patients were stratified into IR-Hi and immuno relation low (IR-Lo) groups. Cancer-specific survival and recurrence-free survival rates were significantly improved in the IR-Hi group compared with in the IT-Lo group. The diversity of the TCR repertoire was significantly higher in the IR-Hi group. TCR repertoire analysis revealed 27 combinations of TCRα and 23 combinations of TCRβ VJ regions that were shared among the IR-Hi group. The IR-Hi group was divided into three clusters. Overall, the current findings revealed that the IR-Hi group maintained the diversity of TCR, and a portion of the IR-Hi cases held the T cells with shared TCR repertoires, implying recognition of shared antigens. The prognosis of patients with ESCC was affected by the existence of immune response cells and may possibly be stratified by the T-cell subsets.

Abstract
Signet ring cell carcinoma (SRCC) is a rare pathological type of colorectal cancer, of which the clinicopathological features and genetic background have not yet been fully investigated. Previous research has focused on the optimization of colorectal cancer treatment utilizing consensus molecular subtyping (CMS). However, it is not known what type of CMS would be designated to SRCC treatment. In the current study, of 1,350 patients diagnosed with colorectal cancer who underwent surgery, 14 were diagnosed with SRCC. The case-control cohort that fit the clinical background of the SRCC case was constructed. Statistical comparison between the SRCC group and the case-control cohort was performed among clinicopathological variables. SRCC and well to moderately adenocarcinoma case mRNA were submitted to microarray analysis and CMS analysis. Compared with the case-control cohort, the SRCC group was located more in the right-sided colon, the lymphatic invasion was more severe and the peritoneal dissemination was more frequent. The cancer-specific survival and the progression-free survival were significantly worse in the SRCC group compared with the case-control cohort. Microarray and CMS analysis identified that one SRCC case was significantly well assigned in the CMS 4 group and the other case was assigned in the CMS 1 group. Gene set analysis revealed the upregulation of EMT related genes and the downregulation of fatty acid, glycolysis, differentiation, MYC, HNF4A, DNA repair genes. In conclusion, the clinical characteristics of SRCC are severe but there is a possibility of the presence of different phenotypes according to CMS analysis.

Abstract
OBJECTIVE Limited information is available regarding the role of programmed death ligand 1 (PD-L1) expression and CD8+ tumor-infiltrating lymphocyte (TIL) density in the tumor immune microenvironment (TIM) of patients with salivary gland carcinoma (SGC). This study aimed to assess the association between the prognosis of SGC patients and the probability of PD-L1 expression in tumor and/or immune cells using the tumor proportion score (TPS), mononuclear immune cell density score (MIDS), combined positive score (CPS), and CD8+ TIL density in the TIM. STUDY DESIGN Retrospective cohort study. METHODS We retrospectively reviewed 73 SGC patients treated with definitive surgery between 2000 and 2015. Immunohistochemical analysis was used to assess TPS, MIDS, CPS, and CD8+ TIL density, followed by prognostic evaluation of these immune-related parameters. RESULTS Histological grade was associated with TPS, MIDS, and CPS based on PD-L1 expression, and these scores exhibited a significant association with CD8+ TIL density. Patients with positive TPS had an unfavorable disease-free survival and overall survival. Multivariate analyses indicated that the TPS was a significant and independent prognostic factor. CONCLUSION Our results suggest that TPS might be a useful prognostic biomarker in SGC patients receiving definitive surgery. Laryngoscope, 131:E1481-E1488, 2021.

Abstract
OBJECTIVES Limited information exists regarding the associations between pre-existing immune parameters in the tumor immune microenvironment (TIM) and either chemoradiosensitivity or prognosis for patients with squamous cell carcinoma of the nasopharynx or oropharynx involving virus-related or nonvirus-related tumors. STUDY DESIGN Retrospective cohort study. METHODS We retrospectively reviewed 141 patients with EBV+, p16+, or EBV- and p16- statuses who are receiving chemoradiotherapy. We performed immunohistochemistry using pretreatment biopsy specimens to analyze the programed death ligand 1 (PD-L1) levels in tumor and immune cells and CD8+ tumor-infiltrating lymphocyte (TIL) density. We evaluated chemoradiosensitivity and prognosis with respect to these immune-related parameters. RESULTS Virus-related tumors showed associations with both PD-L1 expression and high CD8+ TIL density. Patients with higher CD8+ TIL density or greater numbers of PD-L1+ tumor and immune cells showed significant rates of favorable local recurrence-free survival (LRFS), progression-free survival (PFS), and overall survival (OS). Multivariate analyses demonstrated that higher CD8+ TIL density is an independent, significant, and favorable predictive factor for LRFS (P = .005) and OS (P = .003), although it is not a significant predictor of PFS (P = .077). CONCLUSIONS Higher CD8+ TIL density represents a useful and favorable biomarker of chemoradiosensitivity in patients receiving chemoradiotherapy for nasopharyngeal or oropharyngeal cancer.

Abstract
BACKGROUND Little is known about immune-related radiosensitivity in patients with squamous cell carcinoma of the larynx (SCC-L) treated with radiation therapy (RT). METHODS We retrospectively reviewed 91 patients with SCC-L treated with RT or chemoradiation therapy and performed immunohistochemical examination to analyze PD-L1 level on tumor cells, CD4+ tumor-infiltrating lymphocytes (TILs), CD8+ TIL, and FOXP3+ TIL using pretreated biopsy specimens. The association between these immune-related parameters and radiosensitivity was evaluated. RESULTS Multivariate analyses showed that high CD8/FOXP3 ratio combined with negative PD-L1 expression was an independent and significant favorable predictive factor for local control, compared with the other groups. CONCLUSIONS We showed that high CD8/FOXP3 ratio combined with negative PD-L1 expression might be a useful biomarker of radiosensitivity in patients with SCC-L receiving definitive RT. We propose that coassessment of CD8/FOXP3 ratio and PD-L1 expression level in tumor cells can help predict potential radiosensitivity in patients with SCC-L.

Abstract
Although immune checkpoint inhibitors have improved the survival of small cell lung cancer (SCLC) patients, their efficacy in SCLC patients who relapsed after systemic chemotherapy is unclear. This retrospective study aimed to investigate the utility of treatment with atezolizumab plus carboplatin and etoposide in SCLC patients previously treated with platinum-based chemotherapy. We retrospectively screened consecutive eight SCLC patients who received atezolizumab plus carboplatin and etoposide after platinum-based chemotherapy. We evaluated the efficacy of this treatment and its association with programmed cell death-ligand 1 (PD-L1) expression. Three and five patients had sensitive relapse and refractory relapse for first-line platinum-based chemotherapy, respectively. The overall response rate and disease control rate was 37.5% and 75.0%, respectively. Median progression-free survival was 4.0 months. Out of three patients who achieved clinical response, two patients had refractory relapse for first-line platinum-based chemotherapy. No patient exhibited PD-L1 expression. Atezolizumab plus carboplatin and etoposide therapy was effective in SCLC patients with sensitive and refractory relapse and might be a second-line treatment option for SCLC patients previously treated with platinum-based chemotherapy.

Abstract
Squamous cell carcinoma of the head and neck (SCCHN) has a high recurrence rate after (chemo) radiation therapy [(C)RT]. The relationship between the changing levels of immune checkpoint molecules and immune cells in pre-(C)RT tissues and locally recurrent tissues in the irradiated field, after (C)RT completion, is not known. This study aimed to assess the changes in these immune parameters between pre-(C)RT tissue and the same area after local recurrence post-(C)RT. We retrospectively reviewed 30 (C)RT-treated patients with SCCHN. We performed immunohistochemical analyses on these immune parameters using paired tissue samples obtained pre-(C)RT and at local recurrence sites post-(C)RT. No significant changes in immune parameters were found between the pre-(C)RT and locally recurrent tissues. An increased density of CD8+ tumor-infiltrating lymphocytes (TILs) showed a significantly positive correlation with PD-L expression on tumor cells (TC-PD-L1). Patients with increased TC-PD-L1 expression and CD8+TIL density showed favourable prognosis, and one of them showed a favourable response to nivolumab therapy. Our study shows a positive association between TC-PD-L1 upregulation and increased CD8+TIL density, and demonstrates that patients with these changes have a favourable survival outcome.

Abstract
AIM Cancer-associated fibroblasts (CAFs) generated by bone marrow-derived mesenchymal stem cells (BM-MSCs) play an important role in cancer progression. In this study, we investigated the relationships of BM-MSCs and CAFs in resected gastric cancers with the clinicopathological factors of patients. METHODS We analyzed 120 gastric cancer patients who underwent gastrectomy. Immunostaining was performed with an anti-CD271 antibody (BM-MSCs) and anti-α-smooth muscle actin (αSMA) antibody (CAFs). Staining intensity was used to divide patients into low and high expression groups. Observation sites in cancer tissues were invasive, central, and whole portions. RESULTS Expression of αSMA was significantly related to depth of tumor invasion (T), lymph node metastasis (N), lymphatic invasion (ly), venous invasion (v), and stage. Expression of CD271 was significantly related to v, stage, stromal volume, and tumor infiltration pattern (INF). Overall survival (OS) of the high expression group was significantly lower than that of the low expression group for both αSMA and CD271. Multivariate analysis showed that N, αSMA (whole), and CD271 (invasive) were independent prognostic factors. CONCLUSIONS Cancer-associated fibroblasts and BM-MSCs are related to the progression, invasion, and prognosis of gastric cancer and may be therapeutic targets of gastric cancer.

Abstract
Many diseases, including cancer, have been associated with impaired regulation of angiogenesis, of which vascular endothelial growth factor (VEGF)-A is a key regulator. Here, we test the contribution of N-myc downstream regulated gene 1 (NDRG1) to VEGF-A-induced angiogenesis in vascular endothelial cells (ECs). Ndrg1−/− mice exhibit impaired VEGF-A-induced angiogenesis in corneas. Tumor angiogenesis induced by cancer cells that express high levels of VEGF-A was also reduced in a mouse dorsal air sac assay. Furthermore, NDRG1 deficiency in ECs prevented angiogenic sprouting from the aorta and the activation of phospholipase Cγ1 (PLCγ1) and ERK1/2 by VEGF-A without affecting the expression and function of VEGFR2. Finally, we show that NDRG1 formed a complex with PLCγ1 through its phosphorylation sites, and the inhibition of PLCγ1 dramatically suppressed VEGF-A-induced angiogenesis in the mouse cornea, suggesting an essential role of NDRG1 in VEGF-A-induced angiogenesis through PLCγ1 signaling. Kosuke Watari et al. show that N-myc downstream-regulated gene 1 (NDRG1) stimulates new blood vessel formation that is induced by VEGF-A, using Ndrg1 knockout mice. They find that PLCγ1/ERK signaling mediates this regulation, providing mechanistic insights into how vascular endothelial cells form new vessels.

Abstract
BACKGROUND CD73 induces the dephosphorylation of adenosine monophosphate converting it to adenosine, enabling malignancies to escape from immune surveillance. Although CD73 overexpression has been reported to be a poor prognostic factor in several malignancies including non-small cell lung cancer (NSCLC), its predictive relevance in NSCLC patients receiving immune checkpoint inhibitors is unknown. The present research was conducted to investigate the prognostic significance of CD73 expression in NSCLC patients receiving immune checkpoint inhibitors (ICIs). METHODS We screened 91 patients with advanced or recurrent NSCLC who received immune checkpoint inhibitors. CD73 expression was evaluated immunohistochemically using tissue specimens obtained just before treatment with ICIs. RESULTS Analysis of progression-free survival (PFS) and overall survival (OS) in relation to several levels of CD73 expression (1%, 10%, 30%, and 50%) showed that both tended to be more favorable as expression of CD73 increased. PFS and OS were longer for patients in whom at least 50% of the tumor cells expressed CD73 than for those in whom <50% of the tumor cells did so. In patients who were positive for EGFR mutation, immune checkpoint inhibitors were significantly more effective in those with high CD73 expression, whereas CD73 expression did not significantly affect the efficacy in patients with EGFR mutation-negative NSCLC. Furthermore, CD73 expression was predictive factor for the PFS independent of PD-L1 expression in patients with EGFR mutation. CONCLUSIONS High CD73 expression may predict a favorable response to ICIs in NSCLC patients, especially those harboring EGFR mutations. KEY POINTS Significant findings of the study: In patients who were positive for EGFR mutation, immune checkpoint inhibitors (ICIs) were significantly more effective in those with high CD73 expression, whereas CD73 expression did not significantly affect the efficacy in patients with EGFR mutation-negative NSCLC. WHAT THIS STUDY ADDS High CD73 expression may predict a favorable response to immune checkpoint inhibitors in NSCLC patients, especially those harboring EGFR mutations.

Abstract
Nuclear expression of Y-box-binding protein (YBX1) is closely correlated with clinical poor outcomes and drug resistance in breast cancer. Nuclear translocation of YBX1 is facilitated by YBX1 phosphorylation at serine 102 by AKT, p70S6K, and p90RSK, and the phosphorylated YBX1 (pYBX1) promotes expression of genes related to drug resistance and cell growth. A forthcoming problem to be addressed is whether targeting the phosphorylation of YBX1 overcomes antiestrogen resistance by progressive breast cancer. Here, we found that increased expression of pYBX1 was accompanied by acquired resistance to antiestrogens, fulvestrant and tamoxifen. Forced expression of YBX1/S102E, a constitutive phosphorylated form, resulted in acquired resistance to fulvestrant. Inversely, YBX1 silencing specifically overcame antiestrogen resistance. Furthermore, treatment with everolimus, an mTORC1 inhibitor, or TAS0612, a novel multikinase inhibitor of AKT, p70S6K, and p90RSK, suppressed YBX1 phosphorylation and overcame antiestrogen resistance in vitro and in vivo IHC analysis revealed that expression of pYBX1 and YBX1 was augmented in patients who experienced recurrence during treatment with adjuvant endocrine therapies. Furthermore, pYBX1 was highly expressed in patients with triple-negative breast cancer compared with other subtypes. TAS0612 also demonstrated antitumor effect against triple-negative breast cancer in vivo Taken together, our findings suggest that pYBX1 represents a potential therapeutic target for treatment of antiestrogen-resistant and progressive breast cancer.

Abstract
Abstract
[Background] Vascular endothelial growth factor (VEGF)-A is a key regulator of tumor angiogenesis that is essential for tumor growth and progression. The unraveling of the precise mechanisms behind VEGF-A-induced tumor angiogenic process will further contribute to development of novel and potent anti-cancer therapeutics. N-myc downstream regulated gene 1 (NDRG1) has been shown to play essential roles in multiple biological processes including embryogenesis, tissue development, cell growth, differentiation, and tumorigenesis. We previously reported that NDRG1 expression levels in cancer cells are closely correlated with tumor angiogenesis and growth (Hosoi et al., Cancer Res., 2009; Murakami et al., J Biol Chem., 2013), and also that NDRG1 promotes tumor angiogenesis through enhanced VEGF-A production by tumor-associated macrophages (Watari et al., Sci Rep., 2016). However, it remains unclear whether NDRG1 expression in vascular endothelial cells (ECs) plays any crucial role in VEGF-A-induced tumor angiogenesis. In our present study, we further ask whether and how NDRG1 in ECs could specifically regulate tumor angiogenesis. We also present our finding of intrinsic importance that NDRG1 functions as an essential factor for VEGF-A-induced angiogenesis.
[Methods] NDRG1 deficient mice: The NDRG1 deficient mice on C57BL6 background were purchased from Laboratory Animal Resource Bank, National Institutes of Biomedical Innovation, Health and Nutrition (Osaka, Japan). Isolation of mouse endothelial cells: CD31+ endothelial cells were isolated from mouse lung by magnetic sorting using CD31 MicroBeads. Aortic ring assay: 1 mm mouse aortic rings were embedded in 3-dimensional growth factor reduced Matrigel, treated with or without FGF-2 (50 ng/mL) or VEGF (25 ng/ml), and incubated at 37°C. Vascular length and branching point were measured at day 7.
[Results] [1] Analysis of TCGA datasets revealed that NDRG1 expression was positively correlated with VEGF-A expression in patients with various cancer types. [2] In breast cancer patients in Kurume University hospital, NDRG1 was expressed in both cancer cells and ECs. In NDRG1 deficient mice, we observed following experimental results. [3] Both tumor growth and angiogenesis were all suppressed in syngeneic tumors. [4] VEGF-A-induced angiogenesis was specifically impaired in corneal micropocket assay and aortic ring assay, whereas FGF-2 could induce angiogenesis in both assays. [5] NDRG1 formed a complex with PLC-γ, and this complex formation was requisite for the VEGF-A-induced PLCγ/ERK activation in ECs.
[Conclusion] We first present an indispensable role of NDRG1 in VEGF-A-induced angiogenesis through PLCγ/ERK activation in ECs. The NDRG1 could be a novel candidate target for development of therapeutics for VEGF-A-induced tumor angiogenesis and other vascular diseases.

Abstract
Abstract
[Background] Endocrine therapies effectively improve the outcomes of patients with estrogen receptor alpha (ERα)-positive breast cancer. However, the emergence of drug-resistant tumors is a serious challenge. Our previous studies have demonstrated that YBX1 plays pivotal roles in acquisition of endocrine therapy resistance through downregulation of ERα and upregulation of HER2/ErbB2 in breast cancer patients (Shibata et al., Cancer Res., 2017). Furthermore, many laboratories have consistently demonstrated that YBX1 expression is correlated with poor outcomes of breast cancer patients, but the mechanism underlying why YBX1 expression leads to a poor outcome has yet to be revealed. Herein, our present findings demonstrate the critical role of YBX1, and also novel approach to overcome resistance to endocrine therapy.
[Methods] We searched a TCGA database for top 500 genes that are positively or negatively correlated with YBX1 and with ESR1 in breast cancer patients. Furthermore, we established fulvestrant resistant breast cancer cell lines in which AKT/mTORC1/S6K signaling pathway is activated.
[Results] Based on our finding, YBX1 expression is consistently correlated with reduced expression of ERα and its effector genes, conferring breast cancer cells resistance to endocrine therapy. [1] The enhanced expression of YBX1 is negatively correlated with ESR1 and its effector genes in tumors, and also with poor outcomes in breast cancer patients (TCGA and patients in our hospital). [2] Enhanced expression of YBX1 and pYBX1 is closely correlated with recurrence and resistance to endocrine therapy in patients. [3] Breast cancer cells resistant to fulvestrant or tamoxifen showed markedly enhanced expression of pYBX1 and treatment with mTORC1 inhibitors almost completely overcame above resistance in vitro and in vivo. [4] Constitutive activation of YBX1 by the mutant construct induced resistance to fulvestrant, indicating that YBX1 phosphorylation is crucial for the acquired drug resistance. Enhanced expression of YBX1 and also pYBX1 is thus closely associated with endocrine therapy resistance, and also with malignant progression in breast cancer.
[Conclusion] Based on both basic and clinical findings, we will present our novel concept that activation of the oncogenic transcriptional activity by YBX1 phosphorylation is crucial for acquired resistance to endocrine therapy and also poor outcomes in breast cancer. The YBX1 activation by PI3K/AKT/mTOR and RAF/MEK/ERK signaling pathways could be useful candidates for development of overcoming drugs. We will discuss overcoming effects of mTORC1 inhibitors.

Abstract
Aims Limited information is available regarding the precise differences in the tumour immune microenvironment (TIM) of patients with human papilloma virus (HPV)-associated and non-HPV-associated oropharyngeal squamous cell carcinoma (OPSCC). Here, we retrospectively reviewed 137 patients with OPSCC treated with a definitive treatment to identify molecular relationships in the TIM. Materials and methods We used immunohistochemical analysis to assess p16 status, programmed death ligand 1 (PD-L1) level, and/or CD8+ tumour-infiltrating lymphocyte (TIL) density, followed by prognostic evaluation of these immune-related parameters. Results Multivariate analyses demonstrated that PD-L1 level on immune cells but not on tumour cells or CD8+ TIL density was a significant predictive factor of disease-free survival (DFS) and overall survival (OS). Additionally, subgroup analyses demonstrated that patients positive for p16 and PD-L1 expression on immune cells had favourable DFS and OS, whereas patients negative for p16 and PD-L1 expression on immune cells showed worse DFS and OS. Conclusions We demonstrated that PD-L1 expression on immune cells but not tumour cells might represent a useful prognostic biomarker in patients with OPSCC receiving a definitive treatment. We propose that a co-assessment of p16 and PD-L1 expression on immune cells would have greater prognostic potential compared with evaluation of each factor alone in patients with OPSCC.

Abstract
5-Azacytidine (5AC), a hypomethylating agent, is clinically used for the treatment of patients with myelodysplastic syndromes (MDS). Cytidine deaminase (CDA) is a key enzyme in the detoxification of 5AC. We investigated whether the CDA expression could predict response to 5AC in MDS. Among leukemia-derived cell lines, MDS-L, an MDS-derived cell line with a relatively low CDA expression level, was found to be the most sensitive to 5AC. Combination with tetrahydrouridine, an inhibitor of CDA, synergistically potentiated the cytotoxic effect of 5AC. Treatment with 5AC markedly enhanced the expression level of CDA mRNA and showed demethylation at CpG sites in the 5′-flanking region of the CDA gene. We further compared the protein expression levels of CDA in matched clinical samples before and after treatment with 5AC in bone marrow cells from 8 MDS patients by an immunohistochemical analysis. The CDA expression level showed an approximately 2- to 3-fold increase after 5AC treatment in 3 of these cases, and these three patients with relatively higher CDA expression levels after 5AC treatment all showed better clinical responses to 5AC. In contrast, the 5 remaining patients, whose CDA expression showed no augmentation, observed no clinical benefit. Taken together, the optimized determination of the CDA expression levels before and after 5AC treatment, and the methylation status at CpG sites of 5′-flanking region of the CDA gene, may contribute to the development of precise 5AC therapy for MDS.

Abstract
BACKGROUND Programmed death-ligand 1 (PD-L1) expression on lung cancer cells is a prognostic marker and a predictive biomarker for response to immunotherapy. However, previous clinical trials have suggested that other programmed cell death 1 ligands, including programmed death-ligand 2 (PD-L2), might have clinical impacts. This study aimed to analyze the prognostic significance of PD-L2 expression in lung adenocarcinoma patients. METHODS The study included 433 patients who underwent surgical resection for lung adenocarcinoma between 2003 and 2012 at Kyushu University Hospital. Both PD-L1 and PD-L2 expression were evaluated by immunohistochemistry. The cutoff value for PD-L2 positivity was set at 1% according to a time-dependent receiver operating characteristic curve for 5-year survival. RESULTS Of the 433 patients, 306 (70.7%) were positive for PD-L2. No significant association between PD-L1 and PD-L2 expression was observed (P = 0.094). The multivariate analysis showed that the independent predictors of PD-L2 positivity were never-smoker status (P = 0.002), poor differentiation grade (P = 0.008), and advanced stage (P = 0.048). The PD-L2-positive patients had significantly shorter disease-free survival (DFS) (P = 0.018) and overall survival (OS) (P = 0.016). Both PD-L1 and PD-L2 positivity were independent predictors of OS (P < 0.001 and P = 0.027, respectively). In the subgroup analysis of the PD-L1-negative patients, PD-L2 positivity was significantly associated with shorter DFS (P = 0.018). CONCLUSIONS The study demonstrated that the clinical characteristics of patients with PD-L1 expression may differ from those of patients with PD-L2 expression, and that both might contribute to poor prognoses. The potential role of PD-L2 expression as a predictive biomarker for response to immunotherapy should be investigated in future studies.

Abstract
AIM Programmed cell death-ligand 1 and 2 (PD-L1 and PD-L2) are ligands of the programmed cell death-1 (PD1) receptor. PD1/PD-L1 inhibitors have shown clinical efficacy in non-small cell lung cancer (NSCLC). However, relatively little is known about the expression of PD-L2, or its association with the clinicopathological features of NSCLC. Here, the radiological features of PD-L2-positive lung adenocarcinoma were evaluated. MATERIALS AND METHODS PD-L1 and PD-L2 expression were evaluated by immunohistochemical staining of surgically-resected specimens from 393 patients with primary lung adenocarcinoma who underwent preoperative thin-section computed tomography (CT), 222 of whom also underwent 18F-fluorodeoxyglucose positron-emission tomography/CT (18F-FDG-PET/CT). RESULTS Among the 393 specimens, 132 (33.6%) and 266 (67.7%) were positive for PD-L1 and PD-L2 expression, respectively. Multivariate analysis showed that the absence of surrounding ground glass opacity and the presence of air bronchogram were significantly associated with PD-L2 expression; however, there was no significant association between PD-L2 expression and the consolidation/tumor ratio. In 222 18F-FDG-PET/CT, the maximum standardized uptake value was significantly higher in patients with PD-L2-positive compared to those with PD-L2-negative tumors. CONCLUSION PD-L2-positive lung adenocarcinomas are less radiologically malignant and invasive than their PD-L1-positive counterparts.

Abstract
BACKGROUND The cobas® epidermal growth factor receptor (EGFR) Mutation Test v2 designed for cell-free DNA (cfDNA) is approved as a companion diagnostic for osimertinib therapy. The aim of this study was to evaluate the concordance of EGFR mutation detection between paired primary or recurrent samples, and cerebrospinal fluid (CSF) cytology samples of lung cancer patients. METHODS In total, 26 lung cancer patients with supernatant cytology cfDNA in CSF were analysed for EGFR mutations using the cobas® EGFR Mutation Test v2.0 designed for cfDNA, and the concordance rates between CSF cfDNA and primary or recurrent samples were investigated. RESULTS Of the 26 CSF cytology cfDNA samples, 46.1% (12/26) were valid and 53.9% (14/26) were invalid. Sensitivity, specificity and accuracy between the valid CSF cfDNA samples and primary or recurrent samples for detection of EGFR mutation, including T790M were 87.5%, 100.0% and 91.7%, respectively. Amounts of both inflammatory cells and tumour cells in CSF cytology were higher in the valid evaluation samples than in the invalid samples (P < .05), and mutant EGFR was detected in 80.0% (4/5) of the valid CSF cytology cfDNA samples with a negative cytology diagnosis. CONCLUSIONS The cobas® EGFR Mutation Test v2.0 can accurately detect EGFR mutations, including T790M, from supernatant cfDNA of CSF cytology samples. Utilisation of supernatant cytology cfDNA in CSF will allow us to perform both EGFR mutation analysis and cytopathological diagnosis at the same time. This represents a new role of cytology in patient treatment, based on assured sample quality.

Abstract
BACKGROUND In colorectal cancer (CRC), the indication for immune checkpoint inhibitors is determined by the microsatellite instability status of the tumors. However, an optimal biomarker for their indication has not been fully identified to date. This study aimed to establish the clinicopathologic importance of the Immunoscore (IS) in CRC and to clarify the relationships between the IS, programmed death-ligand 1 (PD-L1) expression, and tumor-associated macrophages. METHODS In 132 cases, CRC was diagnosed and surgically treated in our department from 2009 to 2010. Immunohistochemical staining using primary antibodies PD-L1, CD3, CD8, CD68, and CD163 was performed. The IS was determined according to the proposal of an international task force. Statistical analyses were performed to investigate the correlation between the IS, clinicopathologic variables, and expression of immune checkpoint molecules. RESULTS The overall survival (OS) and relapse-free survival (RFS) in the high-IS group (I3-4) were significantly better than in the low-IS group (I0-2) (OS: P = 0.0420; RFS: P = 0.0226). The positivity rate for PD-L1 on tumor cells (tPD-L1) was only 0.8%, whereas that for PD-L1 on interstitial tumor-infiltrating mononuclear cells (iPD-L1) was 18.2%. The iPD-L1-positive group showed significantly better survival in terms of both OS and RFS than the iPD-L1-negative group (OS: P = 0.0278; RFS: P = 0.0253). The findings showed significant correlation between the IS and iPD-L1 expression (P < 0.0001). CONCLUSIONS The study found that a high IS was a good indicator of a better prognosis and significantly correlated with iPD-L1 expression in CRC.

Abstract
BACKGROUND Insulinoma-associated protein 1 (INSM1) has been reported to be a useful marker for diagnosing pancreatic neuroendocrine tumours (PNETs). However, INSM1 expression in endoscopic ultrasound-guided fine needle aspiration cytology has not been examined. We evaluated INSM1 expression in the cytology of cases diagnosed with PNETs. METHODS We immunocytochemically stained INSM1 and Ki-67 in 14 PNET cases, and according to the 2017 World Health Organisation criteria, seven PNET Grade 1 cases, four Grade 2 cases and three Grade 3/neuroendocrine carcinoma cases were identified. As a control for INSM1 and Ki-67 expression, we used cytological specimens from 15 cases of pancreatic ductal adenocarcinoma. RESULTS In PNET cases, INSM1-expressing tumour cells were identified in all cytological specimens of PNET. The median INSM1 expression rate in Grade 1 cases was 49.8% (mean ± standard deviation: 55.1 ± 12.5%, min: 39.3%, max: 74.1%), and in Grade 2 and Grade 3/neuroendocrine carcinoma cases was 81.1% (mean ± standard deviation: 77.6 ± 18.6%, min: 50.3%, max: 100%). However, there was no correlation between INSM1 and Ki-67 expression (r = -0.15). The median expression rate in PNET cases was 64.3%, which was significantly higher than that in pancreatic ductal adenocarcinoma cases (P < 0.0001). CONCLUSION INSM1 immunocytochemistry of cytological specimens obtained from endoscopic ultrasound-guided fine needle aspiration cytology can accurately diagnose PNETs; therefore, INSM1 could be an important diagnostic tool in assessing therapeutic strategies, including molecular-targeted therapy.

Abstract
AIM We examined the programmed death-ligand 1 (PD-L1) expression in surgically resected pancreatic adenosquamous carcinoma (PASC) samples. Furthermore, the detection rate was also assessed using biopsy cases obtained from endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). METHODS Fifteen cases of PASC (six resected and nine EUS-FNA biopsied) from the Kurume University Hospital between 2009 and 2016 were used for the evaluation of PD-L1 expression. As a control group, 34 cases of pancreatic ductal adenocarcinomas (PDACs) were selected. To compare the positivity and intensity of PD-L1, two types of clones (SP263, E1L3N) were examined for immunostaining. Only the membrane expression of PD-L1 was regarded as positive. The PD-L1 expressions in the squamous cell carcinoma component (SCc), adenocarcinoma component (ACc), and immune cells were assessed separately. The ratio of PD-L1 expression was calculated by counting the positive tumor cells, and tumor proportion score (TPS) was applied (TPS; Null < 1%, low expression; 1 ≤ TPS ≤ 49% and high expression; ≥ 50%). RESULTS PD-L1 expression was observed in five surgical PASC samples (83%). This shows that SCc presented a high expression in these cases. However, the overall TPS indicated a low expression. In contrast, only one case (3%) was positive for PD-L1 in PDACs, and the TPS indicated a low expression. No differences in PD-L1 expression were observed between the two clones, SP263 and E1L3N. High PD-L1 expression in the EUS-FNA sample was found in only one case (11%). DISCUSSION Although assessment using the tumor cells of PASC samples obtained from EUS-FNA was difficult, this study suggests the selective expression of PD-L1 in the SCc of PASC. Furthermore, it was considered that immune checkpoint inhibitors could provide therapeutic effects selectively on the SCc for the entire range of TPSs, though the PD-L1 expression was low.

Abstract
BACKGROUND/AIM Although some previous studies suggested that programmed cell death-ligand 1 (PD-L1) expression was significantly associated with a favorable postoperative prognosis in patients with small-cell lung cancer (SCLC), the prognostic significance of PD-L2 expression remains unknown. The aim of the current study was to investigate the prognostic significance of PD-L2 expression in patients with SCLC. PATIENTS AND METHODS Thirty-eight patients who underwent resection of SCLC were analyzed. A monoclonal anti-human PD-L1 antibody (clone SP142) and a monoclonal anti-human PD-L2 antibody (clone 176611) were used as the primary antibodies. Cut-off value for PD-L1 and PD-L2 expression was set to 1%. RESULTS Among 38 patients, 15 (39.5%) were positive for PD-L2 expression. No significant associations between PD-L2-positivity and clinicopathological factors, including PD-L1 positivity or prognosis were identified. No significant differences in disease-free survival and overall survival were observed between PD-L2-positive patients and PD-L2-negative patients (p=0.367 and p=0.726, respectively). CONCLUSION PD-L2 expression is not related to clinicopathological factors or postoperative prognosis in patients with SCLC, though this should be further investigated in studies involving larger populations.

Abstract
BACKGROUND/AIM To investigate the role of programmed cell death-ligand 2 (PD-L2) expression as a predictive biomarker for response to anti-programmed cell death-1 (PD-1) drugs in patients with non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Ten patients who had undergone curative lung resection and received the anti-PD-1 drugs for the recurrence were enrolled. The cut-off value for PD-L2 (antibody clone 176611) expression on tumor cells was set at 50%. Tumor response was evaluated according to immune-related response criteria. RESULTS Seven patients (70.0%) were positive for PD-L2. The response rates were 28.6% (2/7) and 33.3% (1/3) in patients with PD-L2-positive and PD-L2-negative NSCLC, respectively. Disease control was obtained in 2 patients despite the programmed cell death-ligand 1 (PD-L1)-negativity (antibody clone 22C3: 0%, antibody clone SP142: 0%), and these tumors expressed PD-L2 (≥1%). CONCLUSION PD-L2 expression may be a target of immunotherapy in patients with PD-L1-negative NSCLC.

Abstract
OBJECTIVE In renal cell carcinoma (RCC), several prognostic biomarkers have been identified and are under investigation. Several reports have shown that the expression of programmed death 1 (PD-1) and its ligand PD-L1 is associated with poor outcome for patients with RCC. The present study is aimed at evaluating the expression of PD-1 and PD-L1 and to investigate their clinical and prognostic significance in patients with clear cell RCC (CCRCC) having received molecular targeted therapies. In addition, we also evaluated the relationship between the expression of PD-1 and PD-L1 and intratumoral tumor infiltrating lymphocytes (TILs). METHODS A total of 33 patients with metastatic CCRCC who underwent surgery and received molecular targeted therapies from March 2008 to April 2016 were retrospectively reviewed and analyzed. Tissue specimens from the patients were analyzed for PD-1 and PD-L1 expression by immunohistochemistry. RESULTS The median patient age was 64 years old (range=53-78). The majority of patients were male (81.8%). All Memorial Sloan Kettering Cancer Center risk groups were represented among the patients with 39.4% with favorable-, 51.5% with intermediate- and 9.1% with poor-risk. The expression of PD-1 and PD-L1 was observed in 16 (48.5%) and 9 (27.3%) patients, respectively. The expression of PD-1 and PD-L1 was associated with a larger primary renal tumor size, higher nuclear grade and sarcomatoid feature. Kaplan-Meier analysis revealed that no significant difference in progression free survival of first line molecular targeted therapy was found for PD-1 (P=0.2396) and PD-L1 (P=0.5919) expression. However, PD-1 expression has a significant worse impact on overall survival (OS) (P=0.0385), while for PD-L1 expression only a trend is seen for OS (P=0.1542). The patients with PD-1 and PD-L1 expression showed higher infiltration of CD4 (P<0.0001 and P<0.0001, respectively), CD8 (P=0.0328 and P=0.0044, respectively) and FOXP3 (P<0.0001 and P=0.0033, respectively) positive TILs. CONCLUSION PD-1 and PD-L1 expression is significantly associated with adverse clinicopathological features in CCRCC. Furthermore, PD-1 expression could be one of the biomarkers suggesting poor outcome in patients with metastatic CCRCC receiving molecular targeted therapies.

Abstract
Introduction To assess the correlation among 18F-FDG uptake, Glut1, pStat1 and pStat3, and to investigate the relationship between the prognosis and 18F-FDG uptake and these molecular markers in surgically resected non-small cell lung cancer (NSCLC) patients. Results Knockdown of Glut1 led to a significant increase in pStat1 expression. Glut1 expression positively correlated with the SUVmax, SUVmean, and TLG significantly (P<0.001). pStat3 expression negatively correlated with all PET parameters significantly (P<0.001). pStat1 had positive weak correlations with the SUVmax and SUVmean. All PET parameters and Glut1 were significantly associated with DFS (P<0.05). TLG, MTV, Glut1 and pStat1 were significantly associated with OS (P<0.05). Conclusion pStat3 and Glut1 may be associated with 18F-FDG uptake mechanism. TLG, MTV, and Glut1 may be independent prognostic factors. Methods The SUVmax, SUVmean, MTV and TLG of primary lesions were calculated in 140 patients. The expressions of Glut1 and Stat pathway proteins in NSCLC cell lines were examined by immune blots. Excised tumor tissue was analyzed by immunohistochemistry. OS and DFS were evaluated by the Kaplan-Meier method. The difference in survival between subgroups was analyzed by log-rank test. The prognostic significance of clinicopathological, molecular and PET parameters was assessed by Cox proportional hazard regression analysis.

Abstract
OBJECTIVES Although inflammatory markers, such as the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and local immune markers have been shown to have prognostic utility, limited information is available regarding inflammatory and pre-existing tumour-infiltrating lymphocyte density and their association with prognosis in patients with hypopharyngeal squamous cell carcinoma. We investigated the prognostic ability of inflammatory markers and tumour-infiltrating lymphocyte density in stage III and stage IV hypopharyngeal squamous cell carcinoma patients receiving definitive treatment. DESIGN Retrospective cohort study. SETTING Kurume University Hospital. PARTICIPANTS Ninety-six stage III or stage IV hypopharyngeal squamous cell carcinoma patients treated at the Kurume University Hospital between 2000 and 2014. MAIN OUTCOME MEASURES Inflammatory markers and pre-treatment tumour-infiltrating lymphocyte density were examined from recorded haematologic data and immunohistochemical analysis. RESULTS Multivariate analyses showed that the CD8+ tumour-infiltrating lymphocyte density was an independent predictive factor for distant metastasis and overall survival, whereas inflammatory markers, including the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio, were not correlated with distant metastasis or overall survival. CONCLUSIONS Higher pre-treatment CD8+ tumour-infiltrating lymphocyte density is a useful predictive biomarker for reduced distant metastasis and better prognosis.
