Abstract
Serpinb9 is an inhibitor of granzyme B and is potentially involved in the immune escape of tumor cells. In the present study, bioinformatics analysis using open databases suggested that SerpinB9 is overexpressed in testicular embryonal carcinoma. Immunohistological analysis was performed on 28 cases of testicular germ cell tumors to investigate the relationship between SerpinB9 expression in testicular germ cell tumors and the tumor immune environment. SerpinB9 was significantly upregulated in the non-seminoma group and inversely correlated with the number of tumor-infiltrating CD8-positive cells. In addition, yolk sac tumors were characterized by the loss of human leukocyte antigen-class I expression. These findings suggest that SerpinB9 contributes to the immune escape of testicular germ cell tumors. Targeting therapy for SerpinB9 might therefore be useful in immunotherapy for testicular germ cell tumors resistant to immune checkpoint inhibitors.

Abstract
Sinus macrophages in draining lymph nodes (DLNs) are involved in anti-tumor immune reactions. CD169 (Sialoadhesin, Siglec-1) is expressed on sinus macrophages and is considered a surrogate marker for the immunostimulatory phenotype of macrophages. In this study, the significance of sinus macrophages in immunotherapy was evaluated using mouse models. Treatment with anti-programmed death-ligand 1 (PD-L1) antibody suppressed the subcutaneous tumor growth of MC38 and E0771 cells but was not effective against MB49 and LLC tumors. Decreased cytotoxic T-lymphocyte (CTL) infiltration in tumor tissues and CD169 expression in sinus macrophages were observed in MB49 and LLC cells compared to corresponding parameters in MC38 and E0771 cells. The anti-tumor effects of the anti-PD-L1 antibody on MC38 and E0771 cells were abolished when sinus macrophages in DLNs were depleted, suggesting that sinus macrophages are involved in the therapeutic effect of the anti-PD-L1 antibody. Naringin activated sinus macrophages. Naringin inhibited tumor growth in MB49- and LLC-bearing mice but did not affect that in MC38- and E0771-bearing mice. The infiltration of CTLs in tumor tissues and their activation were increased by naringin, and this effect was impaired when sinus macrophages were depleted. Combination therapy with naringin and anti-PD-L1 antibody suppressed MB49 tumor growth. In conclusion, CD169-positive sinus macrophages in DLNs are critical for anti-tumor immune responses, and naringin suppresses tumor growth by activating CD169-positive sinus macrophages and anti-tumor CTL responses. The activation status of sinus macrophages has been suggested to differ among tumor models, and this should be investigated in future studies.

Abstract
Immune checkpoint inhibitors (ICIs) have recently improved the prognosis of various cancers. By contrast, some immune-related adverse events (irAEs) caused by ICIs are fatal and have become problematic. The pathogenesis of irAEs remains unknown and must be elucidated to establish biomarkers. This study investigated plasma cytokine, chemokine, and anti-CD74 autoantibody levels in patients with renal cell carcinoma (RCC) and analyzed their association with irAEs. In a discovery cohort of 13 patients, plasma levels of chemokine (C-X-C motif) ligand (CXCL) 1, IL-17A, IL-1β, IL-6, IL-8, CXCL10, MCP-1, and TNFα were measured at baseline and post-dose 1. Only CXCL10, at post-dose 1 but not at baseline, was significantly associated with grade 2 or higher irAEs (P = 0.0413). Plasma CXCL10 levels were then measured at baseline and post-dose 1 in an extended cohort of 43 patients with RCC who received ICI-based treatment. Higher plasma CXCL10 levels both at baseline and post-dose1 were significantly associated with the occurrence of grade 2 or higher irAEs (P = 0.0246 and 0.0137, respectively). Plasma CXCL13 levels, which we measured in a previous study, were significantly higher in patients with grade 2 or higher irAEs at baseline but not at post-dose 1 (P = 0.0037 and 0.052, respectively). No significant association between plasma anti-CD74 autoantibody level and both irAE pneumonitis and any grade 2 or higher irAE was observed. In conclusion, plasma CXCL10 is significantly associated with the occurrence of irAEs in patients with RCC treated with ICIs. CXCL10 is a potential predictive and on-treatment biomarker for irAEs.

Abstract
BACKGROUND Fumarate hydratase (FH)-deficient renal cell carcinoma (RCC) is a rare RCC subtype, and FH-deficient RCC may be misdiagnosed as another type of RCC, such as type 2 papillary RCC or collecting duct carcinoma. FH and 2-succinocysteine (2SC) are useful diagnostic markers for FH-deficient RCC and can be measured using immunohistochemistry (IHC). CASE REPORT A 30-year-old female with 3-month history of fatigue and left-flank mass was diagnosed with a 20×13×10 cm left-side renal mass with massive inferior vena cava (IVC) tumor thrombus that extended into the right atrium. She underwent nephrectomy and IVC thrombectomy, and a pathological diagnosis of type 2 papillary RCC was made. Four months after the surgery, computed tomography scan showed multiple liver metastases not observed immediately after surgery. Systemic treatment with sorafenib was initiated; however, she did not respond and died 3 months after treatment. Subsequent re-review of hematoxylin and eosin-stained sections indicated morphologic characteristics consistent with FH-deficient RCC, and IHC staining was negative for FH but positive for 2SC, indicating a diagnosis of FH-deficient RCC. Further immunological analyses revealed the loss of HLA-class I, b2 microglobulin, and HLA-DR antigens in cancer cells. In addition, a few CD8-positive cytotoxic T cells and CD163-positive tumor-associated macrophages were noted. CONCLUSION An immunosuppressive tumor microenvironment that facilitates cancer immune evasion might be associated with the rapid progression and poor prognosis in our patient. Further investigation of the tumor immune microenvironment in patients with FH-deficient RCC is warranted.

Abstract
Background: Immune checkpoint inhibitors (ICIs) have recently improved the prognosis of various cancers. In contrast, some immune-related adverse events (irAEs) caused by ICIs are fatal and have become problematic. The pathogenesis of irAEs remains unknown and must be elucidated to establish biomarkers.
Materials and Methods: Plasma samples were collected prospectively from patients with advanced and metastatic renal cell carcinoma (RCC) prior to initiation of ICI treatment (baseline) and 2 or 3 weeks after the first cycle of ICI treatment (post-dose 1). Plasma cytokines and chemokines (GRO [CXCL1], IL-17A, IL-1β, IL-6, IL-8, IP-10 [CXCL10], MCP-1 [CCL2], TNFα) were measured by Luminex system, and plasma level of CXCL13 and anti-CD74 autoantibody levels were measured by ELISA. Their association with irAEs was analyzed.
Results: In a discovery cohort of 13 patients, plasma levels of CXCL1, IL-17A, IL-1β, IL-6, IL-8, CXCL10, MCP-1, and TNFα were measured at baseline and post-dose 1. Only CXCL10, at post-dose 1 but not at baseline, was significantly associated with grade 2 or higher irAEs (p=0.0413). Plasma CXCL10 levels were then measured at baseline and post-dose 1 in a validation cohort of 43 RCC patients who received ICI-based treatment. Higher plasma CXCL10 levels both at baseline and post-dose1 were significantly associated with the occurrence of grade 2 or higher irAEs (p=0.0246 and 0.0137, respectively). We evaluated the relationship between plasma levels of CXCL10 and CXCL13, which we measured in a previous study, and the incidence of irAEs. At baseline, the plasma CXCL13 level was positively associated with the CXCL10 level (p=0.0007), but no significant association was observed post-dose 1 (p=0.2678). Plasma CXCL13 levels were significantly higher in patients with grade 2 or higher irAEs at baseline but not at post-dose 1 (p=0.0037 and 0.052, respectively). No significant association between plasma anti-CD74 autoantibody level and both irAE pneumonitis and any grade 2 or higher irAE was observed.
Conclusion: Plasma CXCL10 is significantly associated with the occurrence of irAEs in patients with RCC treated with ICIs. CXCL10 is a potential predictive and on-treatment biomarker for irAEs.

Abstract
BACKGROUND/AIM Expression of human leukocyte antigen (HLA) class I and II and CD74, which functions as a chaperone of MHC class II, play essential roles in T-cell recognition. The aim of this study was to elucidate the association between the HLAs and CD74, and their correlation with the infiltrated immune cells in renal cell carcinoma (RCC). MATERIALS AND METHODS We retrospectively investigated the expression of HLA-A/B/C, HLA-DR, and CD74 in 38 patients with advanced RCC (T3/T4), and evaluated their correlations with CD4 and CD8-positive T-cell infiltration using immunohistochemistry. RESULTS The expression of HLA-A/B/C, HLA-DR, and CD74 on cancer cells was observed in 37, 20, and 31 patients, respectively. The density of CD8- and CD4-positive T cells showed a positive correlation with HLA-DR expression. The density of CD4-positive lymphocytes was significantly associated with CD74 expression. CONCLUSION The expression of HLA-DR, rather than CD74, on cancer cells was potentially associated with the anti-cancer immune microenvironment.

Abstract
Targeting the programmed cell death-1 signaling pathway has been approved for the anti-cancer therapy in several cancers including urothelial cancer. To determine predictive factors of the responsiveness to pembrolizumab in urothelial cancer patients, a retrospective study that used clinical information and paraffin-embedded samples obtained from patients diagnosed with urothelial cancer between 2015 and 2020 were performed. Seventeen patients who underwent total cystectomy or nephroureterectomy of the primary lesion and were treated with pembrolizumab for chemo-resistant disease were enrolled, and immunohistochemical analysis was performed. A key difference in the characteristics between the non-responder group and the responder group was the age of the patients (74 vs. 63 years, p = 0.0194). Although there was no statistically significant difference, the histological subtype with sarcomatoid and micropapillary components was only seen in the non-responder group, and squamous differentiation and lymph node metastasis were only seen in cases with a complete response. In the results of immunohistochemistry, the density of CD8-positive T-cells and Tregs was significantly increased in the responder group than in the non-responder group. In conclusion, younger age and a high number of tumor-infiltrating lymphocytes were predictive factors of a good response to immune checkpoint inhibitors, although further studies with more enrolled patients are necessary.

Abstract
We measured the electrical conductivity σ of aluminum specimen consisting of submicron-grains by observing the AC magnetic susceptibility resulting from the eddy current. By using a commercial platform for magnetic measurement, contactless measurement of the relative electrical conductivity σn of a nonmagnetic metal is possible over a wide temperature (T) range. By referring to σ at room temperature, obtained by the four-terminal method, σn(T) was transformed into σ(T). This approach is useful for cylinder specimens, in which the estimation of the radius and/or volume is difficult. An experiment in which aluminum underwent accumulative roll bonding, which is a severe plastic deformation process, validated this method of evaluating σ as a function of the fraction of high-angle grain boundaries.

Abstract
INTRODUCTION Bilateral empyema is a rare and life-threatening condition that is difficult to treat. We herein report a case of bilateral empyema that was treated with simultaneous bilateral decortications via video-assisted thoracic surgery (VATS). PRESENTATION OF CASE A 38-year-old female complained of chest pain, dyspnea, and high grade fever lasting two weeks. Computed tomography revealed bilateral notching pleural effusion and pneumonia with atelectasis. Bilateral thoracic drainage was performed. From the right chest, white pus was drained, and Streptococcus anginosus was identified. The left drainage fluid was serous, and no bacteria were identified. We diagnosed the patient with right empyema and left para-pneumonic effusion consequent to pneumonia. Because conservative therapies could not resolve the inflammatory findings, simultaneous bilateral VATS decortications were performed. Both thoracic cavities had loculated pleural effusion. In contrast to the preoperative findings, white pus was found in not only the right, but also the left thoracic cavity. She had an uncomplicated postoperative course and recovered. DISCUSSION Bilateral empyema that has developed to the fibrinopleural phase is difficult to treat with drains alone. Bilateral VATS decortications helped to make a definitive diagnosis and treat both sides simultaneously. CONCLUSION Simultaneous bilateral VATS decortications should be considered as a feasible and effective procedure for bilateral empyema that is refractory to medical treatment.
