Abstract
AIM The spread of lung adenocarcinoma cells into the bronchi and bronchioles is not well documented. We termed this histological finding "endobronchial spreading of adenocarcinoma" (EBSA) and investigated its prevalence and clinical significance. METHODS AND RESULTS We reviewed 320 resected specimens from patients diagnosed with invasive adenocarcinoma, and EBSA was observed in 144 patients (45%). EBSA was significantly associated with advanced pathological stage, higher histological grade, larger tumour invasion, lymphovascular infiltration, and spread through air spaces. Patients with EBSA had significantly shorter relapse-free survival (RFS) and cancer-specific survival (CSS) in univariate analysis (P < 0.001). In a subgroup analysis of patient with small-sized (invasion size ≤30 mm) adenocarcinoma in the localized stage, EBSA was an independent inferior prognostic indicator in multivariate analysis. In a subgroup analysis of patients with small-sized Grade 1 nonmucinous adenocarcinoma (n = 61), EBSA was observed in 11 patients, and the presence of EBSA was associated with significantly shorter RFS and CSS (P = 0.026 and P = 0.001, respectively). CONCLUSION Our results demonstrated that EBSA is a significant risk factor for disease recurrence and cancer-related deaths. EBSA can be regarded as a distinctive pattern of invasion and its recognition can be beneficial in the diagnosis of lung adenocarcinoma.

Abstract
BACKGROUND/AIM Prognostic indicators for postoperative lung adenocarcinoma are elusive. The interaction between CD24 on tumor cells and sialic-acid-binding Ig-like lectin 10 (Siglec10) on tumor-associated macrophages (TAMs) is implicated in immune evasion in distinct tumors. However, the therapeutic significance of phagocytic checkpoints in lung adenocarcinoma remains unknown. We aimed to investigate the clinical relevance and prognostic significance of phagocytosis checkpoints mediated by Siglec10 in TAMs of patients with lung adenocarcinoma who underwent curative resection. PATIENTS AND METHODS In this single-center retrospective study, we analyzed the data of 423 patients with stage I lung adenocarcinoma resected between 1999 and 2016. Tissue microarrays were constructed, and CD24, CD68, and Siglec10 immunohistochemistry was performed. Additionally, we assessed the clinical significance and prognostic associations of these markers. RESULTS CD24 expression was higher in the Siglec10-high expression group than that in the -low expression group. Multivariate analysis showed that combined high Siglec10 and CD24 expression was an independent predictor of recurrence-free probability. The combined high Siglec10 and CD68 expression was a significant independent predictor of overall survival. Univariate analysis demonstrated that the 5-year probability of post-recurrence survival of patients with combined high Siglec10 and CD68 expression was lower than that of the other patients. CONCLUSION High TAM Siglec10 expression and tumor CD24 expression are correlated, and the high Siglec10+CD24 combination is a major risk factor for recurrence. CD68+Siglec10 TAMs are important prognostic factors. Siglec10 expression on TAMs is essential for tumor microenvironment immunoregulation and offers a promising new immunotherapeutic approach for lung adenocarcinoma.

Abstract
BACKGROUND/AIM Immunohistochemical (IHC) staining has been routinely used to distinguish adenocarcinoma (ADC) and squamous cell carcinoma (SCC) of the lungs; however, it is challenging to obtain an accurate diagnosis, especially for cases with discrepancies between IHC and hematoxylin and eosin (H&E) staining results. This study aimed to clarify the clinicopathological characteristics of these discrepant cases. PATIENTS AND METHODS Tissue microarray specimens from 321 patients with ADC and SCC were used for H&E and IHC staining of thyroid transcription factor 1 (TTF-1), Napsin A, cytokeratin 5/6 (CK5/6), p40, and p63. The pathological diagnosis was made based on (1) H&E, (2) IHC, and (3) both H&E and IHC results. Discrepant cases were defined as those with different diagnoses based on the H&E and IHC results. RESULTS A total of 32 (10%) discrepant cases were identified. ADC (3.9%) showed fewer discrepant cases than SCC (51%). Discrepant cases of ADC had a significantly higher proportion of poorly differentiated tumors and subtypes of solid and invasive mucinous ADC, and they also had shorter overall and disease-free survival than concordant cases. Solid and invasive mucinous ADC cases showed low positivity for TTF-1 (84% and 40%, respectively) and Napsin A (88% and 80%, respectively), and invasive mucinous ADC cases showed high positivity for CK5/6 (80%). The sensitivity and specificity of TTF-1+Napsin A for ADC were 91% and 83%, respectively, whereas those of CK5/6+p40 for SCC cases were 90% and 96%, respectively. CONCLUSION Discrepant cases of ADC are associated with solid and invasive mucinous subtypes and shorter survival.

Abstract
A 59-year-old man underwent submandibular gland excision for salivary duct carcinoma (SDC). One year later, esophagogastroduodenoscopy indicated gastric diffuse mucosal thickening with luminal contraction, mimicking scirrhous gastric carcinoma. Biopsy specimens showed dense proliferation of neoplastic cells expressing androgen receptor and human epidermal growth factor 2, indicating SDC. Gastric diffuse infiltrative metastasis is generally characteristic of gastric metastasis from invasive ductal carcinoma, which shows histologic features similar to SDC. This is the first known report of gastric diffusely infiltrating metastasis in an SDC patient. Rapidly progressing, diffuse gastric wall thickening should also be considered indicative of salivary tumor-associated gastric metastasis.

Abstract
Neoadjuvant therapy is commonly used for invasive pancreatic ductal carcinoma (PDAC). Tumor budding and high podoplanin expression in cancer-associated fibroblasts (CAFs) are prognostic factors in patients with various carcinomas including PDAC who have not received neoadjuvant therapy. In this study, we investigated whether tumor budding and podoplanin-positive CAFs are associated with outcomes in Japanese PDAC patients with neoadjuvant therapy. Histopathological findings of surgically resected PDACs with neoadjuvant therapy from 2005 to 2018 were reviewed (n = 97). With reference to International Tumor Budding Consensus Conference recommendations, tumors were evaluated for budding at 20 × magnification (/0.785 mm2) and at 40 × magnification (/0.237 mm2; mean number of fields: 3) for podoplanin expression in CAFs (%). Overall survival, disease-free survival, and disease-specific survival (DSS) were analyzed using the log-rank test and Cox proportional hazards model. After adjusting for T category, N category, resection margin, and adjuvant therapy, multivariate analyses demonstrated that tumor budding at 40 × magnification was an independent prognostic factor for worse DSS (hazard ratio: 2.41, p = 0.022). Tumor budding at 20 × magnification and podoplanin-positive CAFs tended to be associated with worse DSS; however, these findings were not statistically significant. Our findings indicate that tumor budding is an independent prognostic factor in PDAC patients with neoadjuvant therapy.

Abstract
BACKGROUND The incidence of gastric neoplasms in Helicobacter pylori (Hp)-naïve patients has recently increased due to a remarkable decrease in the Hp-infected population in Japan. We investigated the clinicopathologic differences between Hp-infected gastric neoplasms (HpIGNs) and Hp-naïve gastric neoplasms (HpNGNs) that have not been fully elucidated so far. METHODS This retrospective multicenter study investigated 966 consecutive patients with 1131 gastric dysplasia or cancers who underwent endoscopic or surgical treatment for the recent decade. Clinicopathologic features were compared between HpIGN and HpNGN cases. RESULTS One thousand and sixty-eight HpIGNs in 916 patients included 877 differentiated types and 191 undifferentiated types. Sixty-three HpNGNs in 50 patients included 57 differentiated types (35 foveolar types, 15 intestinal types, 6 fundic-gland types, and 1 other differentiated type) and 6 undifferentiated types. HpNGNs occurred in younger (59.5 vs. 71.8 years, p < 0.05) and female patients (40.0% vs. 26.5%, p < 0.05), were found more frequently in the proximal compartment (p < 0.05), and had smaller size (median 4.0 vs. 20.0 mm, p < 0.05). Histologically, HpNGNs and HpIGNs both primarily consisted of differentiated type (90.5% vs. 82.1%, p = 0.089) and HpNGNs showed lower prevalence of invasive cancer (11.1% vs. 37.6%, p < 0.05) and lymphovascular invasion (1.6% vs. 31.6%, p < 0.05). Nearly all HpNGNs (62/63, 98.4%) were diagnosed in early pathological stage, while 16.1% (172/1068) of HpIGNs were diagnosed in advanced stage (p < 0.05). CONCLUSIONS HpNGNs is recently on the increase but shows lower malignant nature regardless of histologic type than HpIGN. Endoscopic gastric cancer screening will be reviewed via cost effectiveness for Hp-naïve individuals in future.

Abstract
Eosinophilic granulomatous polyangiitis is a systemic vasculitis associated with bronchial asthma and eosinophilic sinusitis. Here, we describe an unusual presentation of eosinophilic granulomatous polyangiitis that initially manifested as swelling of the oral cavity floor and cervical soft tissue. A 58 year-old Japanese man was diagnosed with bronchial asthma during childhood but did not receive regular medication. Prior to this presentation, he had a persistent cough for over 1 month, and a local physician diagnosed him with bronchial asthma. However, 6 months later, his cough worsened, and a blood test revealed elevated eosinophil levels. Immediately afterward, swelling of the floor of the oral cavity and cervical soft tissue developed. Cellulitis was suspected and antimicrobial treatment was initiated; however, the symptoms persisted and abdominal pain developed. An endoscopic examination revealed duodenitis and a duodenal ulcer. The patient was diagnosed with eosinophilic granulomatous polyangiitis based on three items of the 2022 American College of Rheumatology/European College of Rheumatology classification criteria: obstructive airway disease, blood eosinophil count ≥1 × 109 cells/L, and extravascular eosinophilic infiltration with a score of 10. Oral prednisolone (70 mg/day), intravenous cyclophosphamide (500 mg/m2), and subcutaneous mepolizumab (300 mg every 4 weeks) were administered. The patient's symptoms improved after these treatments, and the eosinophil count and inflammatory marker levels declined. When swelling of the oral cavity floor and cervical soft tissue following an increase in eosinophilia and allergic symptoms occurs, it is crucial to consider the likelihood of eosinophilic granulomatous polyangiitis and collaborate with otolaryngologists and dentists to ensure its prompt identification.

Abstract
CD44 and CD44 variant isoforms have been reported as contributing factors to cancer progression. In this study, we aimed to assess whether CD44 and its variant isoforms were correlated with the prognostic factors for distant metastasis in stage I lung adenocarcinomas using tissue microarray and immunohistochemistry. In this single-center retrospective study, we analyzed the data of 490 patients with stage I lung adenocarcinoma resected between 1999 and 2016. We constructed tissue microarrays and performed immunohistochemistry for CD44s, CD44v6, and CD44v9. The risk of disease recurrence and its associations with clinicopathological risk factors were assessed. CD44v6 expression was significantly associated with recurrence. Patients with CD44v6-negative tumors had a significantly increased risk of developing distant recurrence than patients with CD44v6-positive tumors (5-year cumulative incidence of recurrence (CIR), 10.7% vs. 4.6%; P = 0.009). However, CD44v6-negative tumors were not associated with an increased risk of locoregional recurrence compared to CD44v6-positive tumors (5-year CIR, 6.0% vs. 4.0%; P = 0.39). The overall survival (OS) of patients with CD44v6-negative tumors was significantly lower than that of patients with CD44v6-positive tumors (5-year OS: 87% vs. 94%, P = 0.016). CD44v6-negative tumors were also associated with invasive tumor size and lymphovascular invasion. Even in stage I disease, tumors with negative-CD44v6 expression had more distant recurrences than those with positive-CD44v6 expression and were associated with poor prognosis in resected stage I lung adenocarcinomas. Thus, CD44v6 downregulation may be a prognostic factor for distant metastasis in stage I lung adenocarcinomas.

Abstract
BACKGROUND/AIM The (pro)renin receptor [(P)RR] plays a role not only in cardiovascular and renal diseases, but also in tumorigenesis. (P)RR contributes to the activation of the Wnt/β-catenin signaling pathway, independent of the renin-angiotensin system. Accumulating evidence has shown that (P)RR is expressed in various human cancers. However, its clinical impact in lung carcinomas remains unclear. This study aimed to clarify the associations between (P)RR expression and clinical outcomes in patients with non-small cell lung carcinoma (NSCLC). PATIENTS AND METHODS We analyzed the data of 913 patients with NSCLC who underwent resection between 1999 and 2016. Tissue microarrays were constructed and the expression of (P)RR and β-catenin was investigated using immunohistochemistry. Recurrence-free probability and overall survival were analyzed using a log-rank test and Cox proportional hazards model. RESULTS In adenocarcinomas, (P)RR down-regulation correlated significantly with high-grade tumors (p=0.026) and a higher risk of recurrence in all patients (p=0.001). Among patients with (P)RR-positive tumors, the nuclear expression of β-catenin was associated with a higher risk of recurrence (p=0.001). Multivariate analysis revealed that (P)RR down-regulation was an independent predictor of disease recurrence (p=0.031). Conversely, in squamous cell carcinoma, (P)RR was not associated with patient outcomes. CONCLUSION (P)RR down-regulation is associated with a higher risk of recurrence in lung adenocarcinomas, thereby characterizing a prognostic subset within high-grade tumors.

Abstract
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest-energy events thought to come from extragalactic sources. Their arrival is infrequent, so detection requires instruments with large collecting areas. In this work, we report the detection of an extremely energetic particle recorded by the surface detector array of the Telescope Array experiment. We calculate the particle's energy as [Formula: see text] (~40 joules). Its arrival direction points back to a void in the large-scale structure of the Universe. Possible explanations include a large deflection by the foreground magnetic field, an unidentified source in the local extragalactic neighborhood, or an incomplete knowledge of particle physics.

Abstract
BACKGROUND Foveolar-type gastric adenoma (FGA) occurs in Helicobacter pylori (Hp)-naïve individuals and morphologically mimics Hp-naïve gastric hyperplastic polyp (HpN-GHP). FGA is often difficult to distinguish from HpN-GHP even by biopsy, due to its low-grade histologic atypia. We conducted a retrospective study to create an endoscopic diagnostic index. METHODS We analyzed 51 FGAs in 41 patients and 36 HpN-GHPs in 24 patients. All lesions were photographed by white-light endoscopy (WLE) and narrow-band imaging with magnification endoscopy (NBIME). Three experts and three non-experts reviewed the WLE and WLE+NBIME images to assess six items for lesion diagnosis. We analyzed correlations between the diagnostic items and histologic features and compared the diagnostic accuracy between modalities. We created a composite diagnostic index and calculated its accuracy and consistency. RESULTS FGAs more frequently showed the following features vs. HpN-GHPs: bright-red color (94.1% vs. 44.4%), peripheral hyperplasia (58.8% vs. 8.3%), papillary/gyrus-like microstructure (96.1% vs. 33.3%), visible capillaries (70.6% vs. 38.9%), and demarcation line (98.0% vs. 41.7%) (P < 0.05). White-zone thickening was seen only in HpN-GHPs (52.8%). Diagnostic accuracy (mean, WLE vs. WLE+NBIME) was 90.8 ± 1.1% vs. 93.5 ± 2.4% (P = 0.15) for experts and 88.5 ± 3.0% vs. 86.6 ± 3.5% (P = 0.51) for non-experts. When satisfying the four criteria (bright-red color, papillary/gyrus-like microstructure, demarcation line, and absent white-zone thickening), sensitivity and specificity for FGA were 90.2% and 94.4%, respectively, with a kappa value of ≥ 0.6 for interobserver diagnostic agreement. CONCLUSIONS Composite diagnostic index contributes to the reproducible, accurate, preoperative differential diagnosis of FGA and HpN-GHP.

Abstract
BACKGROUND/AIM The interleukin (IL)-33/suppression of tumorigenicity 2 (ST2) pathway promotes cancer development and remodels the tumor microenvironment. However, the role of tumoral ST2 expression remains controversial in some solid malignancies. In this study, we have investigated the clinicopathological and prognostic relevance of tumoral ST2 expression in patients with resected pancreatic carcinoma after neoadjuvant chemoradiotherapy. PATIENTS AND METHODS We analyzed data from 76 patients with surgically resected pancreatic ductal adenocarcinoma after neoadjuvant chemoradiotherapy, between 2009 and 2018. Tissue microarrays were constructed and immunohistochemical analysis was performed for ST2. Associations between variables were analyzed using chi-square tests. Disease-specific survival (DSS) and disease-free survival (DFS) were analyzed using log-rank tests. RESULTS High expression of ST2, which was observed in 43 patients (57%), was more frequent in patients with high T status (p=0.002), lymphatic invasion (p=0.049), and ≤50% of tumor cells destroyed by chemoradiotherapy (p=0.043; Evans grade I-IIA vs. IIB). In stage I patients, DFS was significantly lower in patients with high ST2 expression (median, 10.6 months) than in those with low ST2 expression (median, 43.4 months; p=0.046). CONCLUSION High tumoral ST2 expression is associated with high T status, lymphatic invasion, and lower histopathological response grade in patients with pancreatic carcinoma after neoadjuvant chemoradiotherapy.

Abstract
A 78-year-old woman was referred to our institution for evaluation and treatment of a mass on her right adrenal gland measuring 12 × 11 × 10 cm. Twenty-four-hour urine analysis revealed a total metanephrine level over 3 times the upper limit of normal. Scintigraphy using 123I-metaiodobenzylguanidine was positive. The mass was resected en bloc by laparotomy after a laparoscopic attempt was unsuccessful. Histopathologic examination revealed a pheochromocytoma of the right adrenal gland, weighing 576 g. The Grading System for Adrenal Pheochromocytoma and Paraganglioma score was 6, and the histology of the tumor was a moderately differentiated type.

Abstract
Despite recent advances in cancer treatments, pancreatic cancer has a dismal prognosis globally. Early detection of cancer cells and effective treatments for recalcitrant tumors are required, but the innovative therapeutic tools remain in development. Cancer-specific antigens expressed only on cancer cells may help resolve these problems, and antibodies to such antigens have potential in basic research and clinical applications. To generate specific antibodies that bind to proteins expressed on the surface of pancreatic cancer cells, we immunized mice with human pancreatic cancer MIA PaCa-2 cells, and isolated a hybridoma that produces a monoclonal antibody (mAb), named 12-13.8. This antibody was applied to molecular biological experiments such as immunocytochemistry, immunoblotting, flow cytometry, and immunoprecipitation. In addition, we showed that mAb 12-13.8 could accumulate in tumors, through in vivo experiments using cancer-bearing mice. Immunohistochemical staining of pancreatic and lung tumor tissues indicated that the increase of the staining strength by mAb 12-13.8 positively and inversely correlated with the patients' cancer recurrence and survival rate, respectively. We identified the FXYD5 protein as the target protein of mAb 12-13.8, by a human protein array screening system. The FXYD5 protein is overexpressed in various types of cancer and is modified by O-linked glycosylation. We confirmed the binding of the FXYD5 protein to mAb 12-13.8 by using FXYD5-knockout MIA PaCa-2 cells, and detailed epitope mapping identified amino acid residues 45-52 as the minimal peptide sequence. Our results indicate that mAb 12-13.8 could be a valuable tool for FXYD5 studies, and useful in diagnostic and drug delivery applications for cancer patients.

Abstract
This study aimed to compare the recurrence-free survival (RFS) and overall survival (OS) among wedge resection (non-anatomical resection), segmentectomy and lobectomy for pathological stage IA non-small cell lung cancer (NSCLC) with spread through air spaces (STAS). Patients underwent surgical treatment for pathological stage IA NSCLC between January 1, 2005, and March 31, 2016, at our hospital. Surgical procedures were classified as lobectomy, segmentectomy, and wedge resection. Among the 555 analyzed cases, STAS was observed in 148 patients (26.7%). STAS was correlated with worse RFS (P < 0.001) and OS (P < 0.001) and was an independent poor prognostic factor for RFS (hazard ratio: 2.37, P < 0.001) and OS (hazard ratio: 2.02, P < 0.001) in the multivariate analysis. In patients with STAS, the RFS and OS in the segmentectomy group were comparable to those in the lobectomy group. However, the RFS and OS in the wedge resection group were significantly lower than those in the lobectomy group (RFS, P < 0.001; OS, P = 0.001). Wedge resection was an independent prognostic factor for poor RFS (hazard ratio [HR] = 3.87; 95% confidence interval [CI] = 1.84 - 8.12, P < 0.001), and poor OS (hazard ratio [HR] = 3.39; 95% confidence interval [CI] = 1.33 - 8.76, P = 0.011) in the multivariate analysis. Segmentectomy is an adequate operation for patients with stage IA NSCLC with or without STAS. However, wedge resection is associated with a higher risk of recurrence in this patient population.

Abstract
OBJECTIVES The spread through air spaces (STAS) of adenocarcinoma (ADC) is a unique pattern for local invasion, which comprises the spread of tumor cells within air spaces beyond the tumor edge without a direct connection with the primary tumor. Matrix metalloproteinase-7 (MMP-7), a secreted proteolytic enzyme that degrades various extracellular matrix components and other substrates, regulates several pathophysiological processes as well as the occurrence and development of cancers in humans. Here, we retrospectively analyzed a cohort of Japanese patients with treatment-naive, surgically-resected lung ADC to assess whether MMP-7 is associated with STAS development and if it could be used as a predictor of STAS. MATERIALS AND METHODS We performed histological evaluation using hematoxylin and eosin staining and immunohistochemical analysis using microarrays. Thereafter, we scored the examined tissues for immune markers to identify significant tumor STAS predictors. RESULTS We identified that high MMP-7 expression is an independent predictor of a high STAS incidence. Multivariate analysis revealed that MMP-7 expression was correlated with tumor behavior and poor prognosis. Furthermore, STAS remained significantly associated with a higher risk of ADC recurrence. CONCLUSION The development of tumor STAS could be promoted by the functioning of MMP-7. This study could be a crucial basis for future investigations on the detection of tumor STAS.

Abstract
Oxaliplatin, widely used as a chemotherapy drug for colorectal cancer, is known to cause various adverse reactions. In particular, special attention for the development of portal hypertension associated with porto-sinusoidal vascular disease is necessary, as it is a serious adverse life-threating reaction, although rare. We herein report a case of oxaliplatin-related portal hypertension that developed several years after oxaliplatin administration and led to esophageal varices and refractory massive ascites. Clinical physicians should be aware of the possibility of oxaliplatin-induced portal hypertension and its possible development over a long period after discontinuation of the drug.

Abstract
The prognostic impact of tumor-infiltrating lymphocytes (TILs) has been determined in non-small cell lung carcinoma; however, there is no standardized method for counting TILs. In this report, we applied the method proposed by the International Immuno-Oncology Biomarkers Working Group for the assessment of TILs to count the number of tumor-infiltrating neutrophils (TINs). We then analyzed the association between TIL counts, TIN counts, and clinicopathological factors in lung cancer. We retrospectively analyzed a series of 1191 Japanese patients with resected lung adenocarcinoma and squamous cell carcinoma, which were restaged according to the eighth edition of the TNM staging system. Tumors were classified according to the 2015 WHO classification of lung carcinoma. Recurrence-free probability (RFP) and overall survival (OS) were analyzed using the log-rank test and Cox proportional hazard model. Using multivariate analysis for patient outcome in patients with adenocarcinoma, high TIN counts were an independent prognostic factor for worse RFP (hazard ratio [HR]: 1.94, p < 0.001) and worse OS (hazard ratio [HR]: 1.75, p = 0.006). On the other hand, TIL counts were not related to patient outcome. We have demonstrated that high TINs are unfavorable prognostic markers for resected lung adenocarcinoma. In resected lung squamous cell carcinoma, TIL and TIN counts were not related to patient prognosis. It has been suggested that the immune response to cancer cells may differ depending on the histological type. An understanding of how neutrophils are programmed to perform protumor activities is necessary for the future design of targeted immunotherapies.

Abstract
OBJECTIVES A grading system for pulmonary adenocarcinoma has not been established; hence, the International Association for the Study of Lung Cancer (IASLC) pathology panel developed a new grading system for invasive adenocarcinoma. We aimed to evaluate the prognostic significance of the IASLC grading system for invasive pulmonary adenocarcinoma. METHODS We conducted a retrospective analysis of 471 Japanese patients with resected lung adenocarcinoma. Tumors were classified in accordance with the IASLC grading system and 2015 World Health Organization classification. We analyzed recurrence-free probability (RFP) and overall survival (OS) using the log-rank test and compared the two grading systems using the Cox proportional hazards model. RESULTS Grade 3 tumors of the IASLC system and high-grade tumors of the 2015 World Health Organization classification were present in 38% and 17% of patients, respectively. The 5-year RFP was lower in patients with IASLC Grade 3 tumors (45%) than in patients with IASLC Grade 1 and 2 tumors (91% and 83%, respectively). The 5-year RFP of patients with IASLC Grade 2 tumors (83%) was higher than of those with 2015 World Health Organization intermediate tumors (69%). On multivariate analysis for recurrence, IASLC Grade 3 was an independent prognostic factor of worse RFP. We showed similar results on analysis for the OS. CONCLUSIONS The prognostic significance of IASLC Grade 3 tumors on recurrence-free probability was confirmed through both univariate and multivariate analyses. Thus, the IASLC Grade 3 tumor is an independent factor of poor prognosis in patients with resected lung adenocarcinoma.

Abstract
Significant changes in the 2021 World Health Organization (WHO) Classification of Tumors of the Pleura and Pericardium since the 2015 WHO Classification include: 1) Pleural and pericardial tumors have been combined in one chapter whereas in the 2015 WHO, pericardial tumors were classified with cardiac tumors; 2) Well-differentiated papillary mesothelioma (WDPM) has been renamed well-differentiated papillary mesothelial tumor (WDPMT) given growing evidence that these tumors exhibit relatively indolent behavior; 3) Localized and diffuse mesothelioma no longer include the term "malignant" as a prefix; 4) Mesothelioma in situ (MIS) has been added to the 2021 classification since these lesions can now be recognized by loss of BAP1 and/or MTAP by immunohistochemistry and/or CDKN2A homozygous deletion by FISH; 5) The three main histologic subtypes (i.e. epithelioid, biphasic and sarcomatoid) remain the same but architectural patterns, cytologic and stromal features are more formally incorporated into the 2021 classification based on their prognostic significance; 6) Nuclear grading for epithelioid diffuse mesothelioma is introduced and it is recommended to record this and other histologically prognostic features in pathology reports; 7) BAP1, EZH2 and MTAP immunohistochemistry have been shown to be useful in separating benign mesothelial proliferations from mesothelioma; 8) Biphasic mesothelioma can be diagnosed in small biopsies showing both epithelioid and sarcomatoid components even if the amount of one component is less than 10%; and 9) The most frequently altered genes in diffuse pleural mesothelioma include BAP 1, CDKN2A, NF2, TP53, SETD2 and SETB1.

Abstract
PURPOSE Invasive mucinous adenocarcinoma (IMA) is a unique subtype of lung adenocarcinoma, characterized genomically by frequent KRAS mutations or specific gene fusions, most commonly involving NRG1. Comprehensive analysis of a large series of IMAs using broad DNA- and RNA-sequencing methods is still lacking, and it remains unclear whether molecular subtypes of IMA differ clinicopathologically. EXPERIMENTAL DESIGN A total of 200 IMAs were analyzed by 410-gene DNA next-generation sequencing (MSK-IMPACT; n = 136) or hotspot 8-oncogene genotyping (n = 64). Driver-negative cases were further analyzed by 62-gene RNA sequencing (MSK-Fusion) and those lacking fusions were further tested by whole-exome sequencing and whole-transcriptome sequencing (WTS). RESULTS Combined MSK-IMPACT and MSK-Fusion testing identified mutually exclusive driver alterations in 96% of IMAs, including KRAS mutations (76%), NRG1 fusions (7%), ERBB2 alterations (6%), and other less common events. In addition, WTS identified a novel NRG2 fusion (F11R-NRG2). Overall, targetable gene fusions were identified in 51% of KRAS wild-type IMAs, leading to durable responses to targeted therapy in some patients. Compared with KRAS-mutant IMAs, NRG1-rearranged tumors exhibited several more aggressive characteristics, including worse recurrence-free survival (P < 0.0001). CONCLUSIONS This is the largest molecular study of IMAs to date, where we demonstrate the presence of a major oncogenic driver in nearly all cases. This study is the first to document more aggressive characteristics of NRG1-rearranged IMAs, ERBB2 as the third most common alteration, and a novel NRG2 fusion in these tumors. Comprehensive molecular testing of KRAS wild-type IMAs that includes fusion testing is essential, given the high prevalence of alterations with established and investigational targeted therapies in this subset.

Abstract
6p21 translocation renal cell carcinoma (RCC) harboring TFEB gene fusion is a newly classified microphthalmia-associated transcription (MiT) factor-family translocation RCC with early onset. We present a case of 78-year-old man with a 6p21 translocation RCC that was diagnosed after partial nephrectomy for an incidental renal tumor on computed tomography (CT). Unenhanced CT showed a 20 mm, mildly low-density mass in the right kidney. Contrast-enhanced CT showed a heterogeneous and prolonged, mild enhancement in the tumor. On magnetic resonance imaging, the tumor showed iso-intensity within the renal parenchyma on T1-weighted-imaging (WI), low intensity on T2WI, and no restricted diffusion with low signal on diffusion-weighted imaging, with no clear tumor pseudocapsule. Fat poor angiomyolipoma and non-clear cell RCC were listed as differential diagnoses. Robot-assisted partial nephrectomy was successfully performed. Fluorescence in situ hybridization study of the resected tumor confirmed TFEB gene break, and the patient was diagnosed with a 6p21 translocation RCC. The patient is doing well without recurrence after 2.5 years of follow-up. Our patient is the oldest patient reported in previous literature.

Abstract
According to the World Health Organization classification of 2015, spread through air spaces (STAS) is a newly recognized pattern of invasion in lung adenocarcinoma. Many researchers have reported that STAS is recognized in all histological subtypes, and there is a strong association between STAS and prognosis in lung cancer. However, there are several technical issues associated with STAS, such as distinction between the actual in vivo phenomenon and an artifact, difficulty in assessing STAS in frozen specimens, and establishing the relationship between morphological and molecular properties of STAS. This review focuses on the current state of knowledge and the outlook of the STAS phenomenon from the perspective of surgeons, pathologists, and radiologists.

Abstract
It is quite rare that Cushing's disease shows acromegaly, and no pharmacotherapy has yet been discussed. A 21-year-old woman was diagnosed with Cushing's disease and underwent trans-sphenoidal surgery. Five years later, she was diagnosed with recurrent Cushing's disease and biochemical acromegaly because of elevated levels of serum growth hormone (GH), plasma insulin-like growth factor-1, plasma adrenocorticotropic hormone (ACTH), and the 24-hour urinary excretion of free cortisol. After treatment initiation with pasireotide-long-acting release (LAR), both the ACTH and GH declined. Our case is the first to show the efficacy of pasireotide-LAR in controlling both Cushing's disease and acromegaly.

Abstract
OBJECTIVES The prognostic value of spread through air spaces (STAS) in lung carcinoma has been validated in independent cohorts. Epithelial-mesenchymal transition (EMT) is a biological process that promotes the migration and invasiveness of tumor cells. To investigate the role of the EMT phenotype in the occurrence of STAS, we analyzed patients with therapy-naive lung adenocarcinoma and squamous cell carcinoma undergoing lobectomy (n = 635). MATERIALS AND METHODS STAS was defined by the presence of tumor cells within air spaces in the lung parenchyma beyond the edge of the main tumor. The expression of E-cadherin, vimentin, and ®-catenin was evaluated by immunohistochemistry using tissue microarray. Tumors were classified into three EMT phenotypes (epithelial, intermediate, and mesenchymal). Recurrence-free probability and overall survival were analyzed using the log-rank test and the Cox proportional hazards model. RESULTS STAS was less frequently observed in tumors with epithelial phenotype than in those with non-epithelial phenotype (p = 0.034), and more frequent in patients with nuclear β-catenin-positive tumors (p < 0.001). The EMT phenotype was an independent prognostic factor of recurrence (mesenchymal vs. epithelial: hazard ratio [HR] = 2.27, p = 0.014; mesenchymal vs. intermediate: HR = 2.13, p = 0.019). CONCLUSION We have demonstrated that in patients with resected lung carcinoma, STAS was less frequent in tumors with an epithelial phenotype than in those with non-epithelial phenotype, and that the nuclear translocation of β-catenin was associated with a higher rate of STAS. The mesenchymal state was an independent predictor of high risk of recurrence in patients with STAS.

Abstract
Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) and invasive encapsulated follicular variant of papillary thyroid carcinoma (EFV-PTC) are indistinguishable preoperatively. CD26 expression in follicular tumor-uncertain malignant potential (FT-UMP) is reported to be clearly higher than in that without capsular invasion. To verify the diagnostic significance of CD26 immunostaining in EFV-PTC, we examined the expression pattern of CD26 in non-invasive EFV-PTC (NIFTP) and invasive EFV-PTC. We performed immunohistochemical analysis using CD26 antibody for 37 NIFTPs and 54 EFV-PTCs (34 minimally invasive EFV-PTCs and 20 widely invasive EFV-PTCs). Most NIFTP samples showed an apical membranous pattern or a cytoplasmic diffuse pattern of expression. Invasive EFV-PTCs more frequently showed a cytoplasmic dot-like pattern, and the labeling indices of tumor cells with cytoplasmic dot-like patterns were significantly higher than those in NIFTPs. The sizes of dots seen in NIFTPs (mean: 1.12 μm) were significantly smaller than in invasive EFV-PTCs (1.33 μm), minimally invasive EFV-PTC (1.27 μm), and widely invasive EFV-PTC (1.38 μm). We, therefore, conclude that cytoplasmic diffuse and/or cytoplasmic dot-like CD26 expression, particularly the larger CD26-positive dots, could be useful markers for capsular invasion in EFV-PTC. CD26 immunostaining, using cell blocks or cytological specimens, may preoperatively distinguish between NIFTP and invasive EFV-PTC.

Abstract
Abstract
Background
Impact of ischemic risk (IR) on long term outcomes in patients at high bleeding risk (HBR) after everolimus-eluting stent (EES) implantation remains unclear.
Purpose
We aimed to evaluate long term bleeding and ischemic events in patient with HBR or IR after EES implantation.
Methods
The study population comprised 1219 patients treated with EES without in-hospital events between 2010 and 2011. The follow-up period was 2996±433 days. HBR was defined as Academic research consortium. IR defined as high-risk features of stent-driven recurrent ischemic events in Europe society of cardiology guidelines in 2019: prior stent thrombosis on adequate antiplatelet therapy, diffuse multivessel disease especially in diabetic patients, creatinine clearance <60 ml/min, at least three stents implanted, bifurcation two stents implanted, total stent length >60 mm, and treatment of a chronic total occlusion. Major bleeding (MB) was defined as defined as the occurrence of a Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding event. Primary ischemic events included myocardial infarction, definite stent thrombosis, and cardiac death. The Kaplan-Meier method was used for time-to-event analyses.
Results
Of the 1219 patients, 317 (26.0%) patients had no risk, 114 (9.4%) patients had only HBR, 288 (23.6%) patients had only IR, and 500 (41.0%) patients had both risks. The 81.4% of HBR patients had IR. The figure of Kaplan-Meier showed MB and CE for 7–8 years. Both risk groups had higher bleeding risk and Ischemic events (log rank p=0.0039, 0.0001).
Conclusion
HBR patients with EES had a high incidence of IR. Patients who had both HBR and IR are especially at risk for both ischemic events and bleeding compared to those who had no or only one risk.

Abstract
Abstract
Background
It is yet to be known whether mechanisms underlying restenosis in newer-generation durable-polymer (DP) and biodegradable-polymer (BP) drug-eluting stents (DES) are different.
Purpose
This study aims to assess the incidences and predictors of early restenosis and late catch-up phenomenon after newer-generation durable-polymer (DP) and biodegradable-polymer (BP) DES.
Methods
Between 2010 and 2017, 13858 lesions in 6350 patients were treated with DES (4393 BP-DES, 9465 DP-DES). The early-term (within 1 year) and late-term (from 1 to 2 years) follow-up angiographies were scheduled. Late catch-up phenomenon was defined as in-stent restenosis (ISR) in lesions that evaded ISR within 1 year after stent implantation. ISR was defined as angiographic restenosis of more than 50%.
Results
The mean patient age was 71 years, and 76.7% were male. Early-term angiographies were performed in 10955 lesions (79.0%). Of those without early-term ISR, late-term angiographies were performed in 7771 lesions (56.1%). The incidences of mid-term restenosis and late catch-up phenomenon were 6.6% and 3.9%, respectively.
In the multivariate regression analyses, history of diabetes, hemodialysis and previous PCI were independent predictors of both early restenosis and late catch-up phenomenon. Also, some lesion characteristics such as chronic total occlusion, right coronary artery ostial lesion, small vessel (defined as reference diameter <2.5mm), long lesion (defined as lesion length >30mm) and treatment of ISR lesion were independent predictors of both early restenosis and late catch-up phenomenon.
Bifurcation lesion and heavily calcified lesion treated with rotablator were independent risk of early restenosis. Bypass graft lesion was an independent predictor of late catch-up phenomenon.
Early restenosis was observed less frequently in DP-DES than in BP-DES (6.3% versus 7.4%, P=0.012). On the contrary, late catch-up phenomenon was observed more frequently in DP-DES than in BP-DES (4.3% versus 2.9%, P=0.026).
Conclusions
Some lesion characteristics were independent predictors of early restenosis and late catch-up phenomenon after newer-generation DES implantation. The deployment of BP-DES resulted in more early restenosis and less late catch-up phenomenon compared to that of DP-DES.

Abstract
Abstract
Background
Coronary artery embolism (CE) is one of the important causes of acute coronary syndrome (ACS). The feature of CE is that angiographic evidence of coronary artery embolism and thrombosis without atherosclerotic components. However, the prevalence of CE remains unknown because of the diffifulty to diagnose in the acute settings. A recent retrospective analysis suggested that up to 3% of ACS cases may result from CE.
Purpose
The aim of this study was to elucidate the prevalence, clinical features and long-term outcomes including all-cause and cardiac death.
Methods
We analysed the consecutive 2695 patients with first AMI performed coronary intervention between January 2004 and July 2017. CE was diagnosed by clinical histories and angiographic findings. We retrospectively evaluated the clinical and lesion characteristics and outcomes including all-cause and cardiac death.
Results
The prevalence of CE was 2.0% (n=55; CE group and n=2640; non-CE group), including 8 (15%) patients with multivessel CE. The CE group had higher average age (70.8±14.9 vs. 68.4±12.6, p<0.01), prevalence of female (54% vs. 27%, p<0.01), lower prevalence of smoking (34% vs. 62%, p<0.01). The common causes with CE were atrial fibrillation (47%), and malignant tumor (9%), and cardiomyopathy (5%), and patent foramen ovale (4%). Only 20% of patients with CE were treated with anti-coagulant therapy. The rate of distal infarction site (defined as #4, #8, #14–15) was significantly higher in CE group than non-CE group (54.0% vs. 4.9%, p<0.01). During median follow-up of 53.6 [32.6–77.3] months, CE and thromboembolism recurred in 5 patients (CE: 1 patient, stroke 4 patients). The 4-year incidence of all-cause death was significantly higher in the CE group, but cardiac death was not significantly different between the groups (28.8% vs. 14.8%, p=0.03; 12.8% vs. 5.1%, p=0.11).
Conclusion
Compared with non-CE group, the prevalence of distal infarction site was significantly higher in the CE group, and the incidence of cardiac death is not significantly different.

Abstract
Abstract
Background
Recently, the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria has been suggested as the standard definition of HBR.
Purpose
We aimed to investigate the risk stratification based on ARC-HBR Criteria for long-term bleeding event after everolimus-eluting stent implantation
Methods
The study population comprised 1193 patients treated with EES without in-hospital event between 2010 and 2011. Individual ARC-HBR criteria was retrospectively assessed. Major bleeding were defined as the occurrence of a Bleeding Academic Research Consortium type 3 or 5 bleeding event. The mean follow-up period was 2996±433 days.
Results
There were 656 patients (55.0%) in HBR-groups. Cumulative incidence of major bleeding was significantly higher in HBR-group (8.1% vs 3.4% at 4 year, and 16.2% vs 5.7% at 8 year, P<0.001). Cumulative rate of major bleeding tend to be higher as the number of ARC-HBR criteria increased (≥2 Majors: 24.3%, 1 Major: 17.0%, ≥2 Minors:11.7%, and Non-HBR: 5.7%, P<0.001).
Conclusion
ARC-HBR criteria successfully stratified the long-term bleeding risk after drug-eluting stent implantation in real-world practice.

Abstract
BACKGROUND It is difficult to obtain a definitive diagnosis for nodular smooth muscle proliferation (NSMP) before surgery, and a pathological diagnosis is necessary to differentiate it from primary lung cancer. We report two cases of NSMP that were suspected to be primary lung cancer on preoperative images. CASE PRESENTATION Case 1: An 81-year-old man who had undergone right upper lobectomy for lung cancer 2 years earlier was point out a nodular shadow with ground glass opacity (GGO) in the lower right lobe, suggesting a second primary lung cancer by chest computed tomography (CT). A thoracoscopic partial resection of the right lower lobe was performed, and pathological diagnosis was NSMP. The patient was discharged without any problems at 3 days postoperatively. Case 2: A 72-year-old woman was pointed out a nodular shadow suspected primary lung cancer in the left lower lobe by chest CT. Therefore, thoracoscopic partial resection of the left lower lobe was performed, and pathological diagnosis was NSMP. The patient was discharged without any problems at 5 days postoperatively. CONCLUSION This report demonstrates that NSMP can be distinguished from leiomyoma and hamartoma by imaging features and pathological findings.

Abstract
Background Cryofibrinogenemia is a rare disorder that mainly affects the skin and occasionally the kidney. However, there are few published reports of cryofibrinogenemia-associated renal pathology. We therefore report a patient with cryofibrinogen-associated glomerulonephritis. Samples from this patient were examined by electron microscopy, laser microdissection, and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Case presentation A 78-year-old Japanese man presented with declining renal function, proteinuria, and gross hematuria. Kidney biopsy showed a membranoproliferative pattern with crescent formation and dominant C3c deposition in which subendothelial deposits with uniquely organized electron-microscopic features were observed. Additional ultrastructural analysis of cryoprecipitates extracted from plasma revealed similar structures of the glomerular subendothelial deposits. LC-MS/MS identified an increase in fibrinogen α, β, and γ chains, fibronectin, filamin-A, and C3. The glomerular lesions were diagnosed as cryofibrinogen-associated glomerulonephritis on the basis of these findings. Conclusions Although there are few reports of cryofibrinogen-associated glomerulonephritis, we believe that accurate diagnosis can be achieved by performing LC-MS/MS and ultrastructural analysis.

Abstract
Epithelioid glioblastoma is a rare subtype of glioblastoma, but the coexistence of a sarcomatous component is even rarer. An 80-year-old woman was admitted to our hospital with somnolence. Magnetic resonance imaging revealed a cystic lesion with a solid component in the left temporal-parietal lobe. Histopathological examination of the resected tumor revealed three components; namely, typical glioblastoma, sarcomatous and epithelioid components at a ratio of about 5:3:2. All components were immunohistochemically positive for vimentin and mutated BRAF (V600E) and showed focal expression of glial fibrillary acidic protein and cytokeratin AE1/AE3, but they were negative for isocitrate dehydrogenase 1. Genetic analysis revealed that both the sarcomatous and epithelioid components harbored BRAF T1799A (V600E) mutation and homozygous deletion of cyclin-dependent kinase inhibitor 2A/B. We diagnosed this tumor as epithelial glioblastoma with a sarcomatous component. Our results indicate that even when the epithelial component is not dominant, immunohistochemical and genetic investigation of BRAF mutations is useful for the diagnosis of glioblastoma subtypes. In particular, although the prognosis of epithelial glioblastoma is poor, potentially effective targeted therapies for BRAF V600E-mutated tumors are available.

Abstract
Abstract
Background
The second generation drug-eluting stent (G2-DES) has been reported as superior to the first generation drug-eluting stent (G1-DES) in mid-term outcomes. However, the late-term outcomes between G1-DES and G2-DES in two-stenting for coronary bifurcation lesions are not well studied.
Purpose
To evaluate the late catch-up phenomenon and late-term target lesion revascularization (TLR) of two-stenting for coronary bifurcation lesions between G1-DES and G2-DES.
Methods
This study included 1133 lesions in 1089 patients undergoing drug eluting stent implantation with two stenting from 2004 to 2016. These consisted of 496 G1-DES implanted lesions and 637 G2-DES implanted lesions. Late-term follow-up angiography was performed without in-stent restenosis (ISR) and TLR at mid-term follow-up in 582 lesions (242 G1-DES lesions and 340 G2-DES lesions). ISR was defined as more than 50% restenosis. Late catch-up phenomenon was defined as ISR without ISR within 1 year following index stent implantation. Late-term TLR was defined as from 1 to 5 year TLR. Bifurcation lesions were defined as the main branch ranging from the proximal stem to the distal main branch with boundaries defined by 5 mm proximal and distal to the stent-implanted area, and the side branch ranging from the bifurcation carina to the distal side branch with boundaries defined by the carina and 5 mm distal to the stent-implanted area.
Results
The median follow-up duration was 5.1 years (the first and third quarters, 3.2 and 7.1 years). The late-catch up phenomenon rate significantly differed between the G1-DES and G2-DES groups (16.9% vs 8.4%, p=0.001). A significant difference in late catch-up between the same two groups was also observed in bifurcation lesions of the main branch (5.0% vs 0.6%, p=0.001) and side branch (10.3% vs 5.6%, p=0.033), respectively. The 5-year cumulative rates also differed between the two groups in TLR (8.2% vs 3.7% log-rank p=0.001), and late-term TLR (7.0% vs 3.6% log-rank p=0.001).
Conclusion
Two-stenting using G2-DES, compared with G1-DES, significantly reduced late-term restenosis and TLR. The restenosis rate in bifurcation area may be associated with differences between two groups in late-term outcome.

Abstract
Abstract
Background
It was reported that tissue morphology of in-stent restenosis (ISR) lesions assessed with optical coherence tomography (OCT) had an effect on midterm results including ISR and target lesion revascularization (TLR) rates after percutaneous coronary intervention (PCI). However, little was known about the association between tissue morphology assessed with OCT and late-term results.
Methods
We performed PCI treated with paclitaxel coated balloon (PCB) or drug-eluting stent (DES) for 452 ISR lesions (260 lesions with fibrous plaque and 192 lesions with lipid-laden plaque) using OCT between May 2008 and July 2016. Six- to eight-month (midterm) angiographic follow-up was performed on 422 of the 452 ISR lesions (follow-up rate: 93.4%). Furthermore, eighteen- to twenty-month (late-term) angiographic follow-up was performed on 337 of the 361 ISR lesions (follow-up rate: 93.4%) which were free from midterm TLR. We examined the association between tissue morphology, midterm-results and late-term results including ISR and TLR rates. Fibrous plaque was defined as homogeneous, signal-rich regions with low attenuation. Lipid-laden plaque was defined as diffuse border, signal poor regions with high attenuation.
Results
The patients were 353 men and 69 women, and the mean age was 68.8±9.6 years. PCI were performed with PCB in 285 lesions (PCB group) and DES in 137 lesions (DES group). The figure shows the angiographic midterm results of the 422 lesions and late-term results of the 337 lesions with respect to each tissue morphology and each PCI device. There was no difference in ISR and TLR rates of lesions with both fibrous and lipid-laden plaque at midterm between the two groups. ISR and TLR rates of lesions with lipid-laden plaque at late-term were significantly higher in the PCB group than in the DES group, while there was no difference in ISR and TLR rates of lesions with fibrous plaque at late-term between two groups.
Figure 1
Conclusion
Tissue morphology of ISR lesions might have an impact on outcomes after PCI. Morphological assessment of ISR tissue using OCT might suggest favorable types of PCI for ISR lesions.

Abstract
Abstract
Background
Whether preparation techniques during percutaneous coronary intervention (PCI) are associated with restenosis in severely calcified lesions is not well studied.
Purpose
We aimed to clarify the effects of the preparation techniques during PCI on mid-term outcomes of severely calcified lesions.
Methods
We examined 2688 consecutive severely calcified lesions (1854 patients) treated by PCI between January 2008 and December 2017, and identified 1789 lesions (66.6%) undergoing routine follow-up angiography within one year postprocedure. The angiographic outcome measure was defined as in-stent restenosis (ISR); ISR was defined as stenosis of ≥50%. We divided the 1789 lesions into two groups on the basis of the presence or absence of ISR: ISR and non-ISR groups.
Result
ISR was detected in 337 of the 1789 lesions (18.8%). The ISR group, in comparison with the non-ISR group, had more chronic total occlusion lesions (17.9% vs. 12%, p<0.01), less bifurcation lesions (41.9% vs. 48.5%, p=0.03), less reference diameter (2.85±0.64 mm2 vs. 2.96±0.54 mm2, p<0.01), lower use rate of scoring or cutting balloon (13.9% vs. 23.1%, p<0.01), and lower postprocedural percent stenosis (25.9±20.7% vs. 16.9±9.3%, p<0.01). After adjusting chronic total occlusion lesions, target lesions, and other factors in multiple logistic regression models, the use of scoring or cutting balloon was independently associated with ISR (hazard ratio, 0.62; 95% confidence interval, 0.44 to 0.89; p<0.01).
Conclusion
Using scoring or cutting balloon is associated with good midterm results of severely calcified lesions treated by PCI.

Abstract
Abstract
Background
Organ injury in heart failure (HF) might evoke profibrotic response, which might adversely affect prognosis.In patients with HF, liver fibrogenesis marker, type IV collagen 7S (P4NP 7S), correlates with pulmonary artery pressure and right-side cardiac pressure such as right atrial and ventricular pressure. The present study aimed to investigate the prognostic utility of two collagen markers (N-terminal propeptide of procollagen III [PIIINP] and P4NP 7S) in patients with acute HF.
Methods and results
We conducted a prospective cohort study including 390 patients admitted for HF to three territorial hospitals. The pre-specified primary outcome measure was cardiac death and HF hospitalization at early (90-day) and late (365-day) post-discharge period. Follow-up ratio was 99% at 90 day and 97% at 365 day, respectively. Cardiac death and HF hospitalization occurred in 61 and 114 patients at 90 days and 365 days, respectively. The dichotomization the patients based on the median value of the collagen marker at discharge revealed that patients with high P4NP 7S correlated with significant excess risk relative to those with low P4NP 7S for 90-day (adjusted hazard ratio [HR]; 1.89, 95% confidence interval [CI]); 1.11–3.26, P=0.02) and 365-day (adjusted HR; 1.50, 95% CI; 1.02–2.21, P=0.04) outcome. 10% increase in P4NP 7S was associated with 8% increase for primary outcome measure at 90 day (P=0.04). P4NP 7S showed incremental prognostic value on top of the conventional prognostic factors including age, sex, estimated glomerular filtration rate (eGFR), ejection fraction (EF) <40%, B-type natriuretic peptide (BNP), hemoglobin and sodium <140mmol/L (P=0.038 for net reclassification improvement, P=0.0068 for integrated discrimination improvement). PIIINP weakly correlated with P4NP 7S (Spearman's r=0.24, P<0.0001), but it neither correrated with the marked excess risk not associated with significant excess risk for 90 and 365-day primary outcome measure nor enhanced the discrimination.
Conclusions
This study suggests a possible role of P4NP 7S in the risk stratification of patients with acute HF.

Abstract
Abstract
Background
The incidence of aortic dissection has been reported to be lower in women; however, women have a poor prognosis. Also, the incidence of false lumen thrombosis has been reported to be different between Europe, the United States, and Japan. We aimed to determine gender differences in long-term prognosis of acute type B aortic dissection.
Methods
We retrospectively reviewed 220 consecutive patients hospitalized for acute type B aortic dissection between January 2012 to December 2017. After exclusion criteria of unknown onset time, >14 days after the onset, in-hospital death, and aortic events requiring additional treatment during hospitalization were applied, 186 patients were analyzed by gender: 133 men and 53 women. The patient background, treatment method, prognosis, and outcome were compared and examined.
Results
Both the proportions of smoking history and patients receiving oxygen therapy during hospitalization were significantly higher in men (59% vs. 22%, p<0.01; 91% vs. 72%, p<0.01, respectively), whereas that of classical aortic dissection was similar between men and women (41% vs. 32%, p=0.36). The avoidance rate of a composite of all deaths and aortic events 2 years after discharge was similar (hazard ratio, 0.99; 95% confidence interval, 0.52 to 1.59; p=0.966).(Picture1)
Picture 1
Conclusion
The long-term prognosis of acute type B aortic dissection treated by medical therapy during hospitalization was equivalent in men and women despite gender differences in several background factors.

Abstract
Background
Successful recanalisation of percutaneous coronary intervention for chronic total occlusion lesions has been associated with improved survival.
Purpose
This study aimed to assess the impact of successful percutaneous coronary intervention for chronic total occlusion lesions on the long-term outcome of patients with impaired and preserved left ventricular ejection fraction (LVEF).
Methods
The study sample consisted of 842 consecutive patients (928 chronic total occlusion lesions) undergoing percutaneous coronary intervention at our institution between October 2005 and December 2009. We divided them into 3 groups by the degree of LVEF: less than 40% (severely reduced LVEF, n=140), 40% to 59% (moderately reduced LVEF, n=470), and 60% and above (normal LVEF, n=232). We evaluated mortality during the 10-year follow-up period the basis of procedural success and failure.
Results
The overall procedural success rate was 89.1%. Median follow-up duration was 7.9 years. The 10-year cumulative incidences of cardiac death in each degree of LVEF are shown in the Figure.
Conclusions
Successful recanalisation for chronic total occlusion lesions in patients with impaired LVEF may be associated with reduced cardiac mortality.

Abstract
Background Cytokeratins and Vimentin are intermediate filament proteins. Vimentin expression in tissue samples has been reported to be associated with a poor prognosis in non-small cell lung cancer patients who underwent surgery. CYFRA 21-1 (Cytokeratin 19 Fragment) is a well known tumor marker. Objective This study aimed to investigate the usefulness of serum vimentin as a tumor marker and significance of CYFRA 21-1 and vimentin expression on prognosis of advanced lung cancer patients. Methods One hundred and four advanced lung cancer patients and 19 non-lung cancer patients were included. A total of 157 clinical samples obtained from 113 patients was used for immunostaining of vimentin and measurements of CYFRA 21-1 and vimentin concentrations. Results Compared to low concentration, high concentration of serum CYFRA 21-1 was associated with shorter overall survival in lung cancer patients. However, there was no difference in the serum vimentin concentration between the patients with lung cancer and those with non-lung cancer. No difference in vimentin concentration was observed between the malignant and non-malignant pleural effusions. Immunostaining revealed that of the 43 tumor samples, 21 were positive and 22 were negative for vimentin. No significant difference was found in overall survival between patients with positive and negative for vimentin. Conclusion An elevated serum CYFRA 21-1 concentration was associated with shorter overall survival in advanced lung cancer patients. However, serum vimentin was not as useful as a tumor marker of lung cancer. The vimentin positivity in tumor samples might not predict patients' prognosis in patients with advanced lung cancer.

Abstract
A 67-year-old man visited hospital because of prolonged cough. Chest computed tomography (CT) revealed multiple tumors in bilateral lungs. Transbronchial lung biopsy did not reveal malignancy. Because antibiotic treatment was ineffective, partial resection of the right lung was performed for establishing the diagnosis. The pathological diagnosis was inflammatory myofibroblastic tumor. The postoperative course was uneventful. After 6 months postsurgery, he complained of breathing difficulty and exacerbation of the lesions was found by chest CT. By methylprednisolone pulse therapy, the symptom was improved, and the size of lesions reduced. Since this event, he has been administered oral prednisolone (PSL) 10 mg/day, and the exacerbation of the disease has not been noted.

Abstract
We herein present the case of a 27-year-old woman with clinical and biochemical features of virilism. Imaging studies revealed the presence of a bilateral adrenal tumor. Although the secretion of androgens was remarkable, the autonomous production of cortisol was also evident because of a loss of circadian rhythm and the absence of cortisol suppression by dexamethasone. The surgical excision of both adrenal tumors was performed, and the histological examination showed no malignancy. We also report the successful pregnancy and delivery of the patient who showed evolving adrenocortical insufficiency along with virilization and Cushing's syndrome and who continued to receive glucocorticoid replacement therapy during pregnancy.

Abstract
INTRODUCTION This work was performed to develop and validate procedure-specific risk prediction for recurrence following resection for early-stage lung adenocarcinoma (ADC) and investigate risk prediction utility in identifying patients who may benefit from adjuvant chemotherapy (ACT). METHODS In patients who underwent resection for small (≤2 cm) lung ADC (lobectomy, 557; sublobar resection, 352), an association between clinicopathologic variables and risk of recurrence was assessed by a competing risks approach. Procedure-specific risk prediction was developed based on multivariable regression for recurrence. External validation was conducted using cohorts (N = 708) from Japan, Taiwan, and Germany. The accuracy of risk prediction was measured using a concordance index. We applied the lobectomy risk prediction approach to a propensity score-matched cohort of patients with stage II-III disease (n = 316, after matching) with or without ACT and compared lung cancer-specific survival between groups among low- or high-risk scores. RESULTS Micropapillary pattern, solid pattern, lymphovascular invasion, and necrosis were involved in the risk prediction following lobectomy, and micropapillary pattern, spread through air spaces, lymphovascular invasion, and necrosis following sublobar resection. Both internal and external validation showed good discrimination (concordance index in lobectomy and sublobar resection: internal, 0.77 and 0.75, respectively; and external, 0.73 and 0.79, respectively). In the stage II-III propensity score-matched cohort, among high-risk patients, ACT significantly reduced the risk of lung cancer-specific death (subhazard ratio 0.43, p = 0.001), but not among low-risk patients. CONCLUSIONS Procedure-specific risk prediction for patients with resected small lung ADC can be used to better prognosticate and stratify patients for further interventions.

Abstract
INTRODUCTION The eighth edition of the TNM staging system included the proposal that the T descriptor be determined according to the invasive component, excluding lepidic component, for nonmucinous lung adenocarcinomas. We sought to conduct a clinicopathologic comparative analysis of the newly proposed classification using invasive size versus total tumor size. METHODS Patients who underwent lung resection for primary lung adenocarcinoma with pathologic stage (p-Stage) I-IIA (based on total size [t]) were reviewed (n = 1704). Pathologic invasive size was measured, and tumors were reclassified using invasive size (i). Cumulative incidence of recurrence and lung cancer-specific cumulative incidence of death were analyzed using a competing-risks approach. Prognostic discrimination by p-Stage(t) and p-Stage(i) was evaluated using a concordance index (C-index). RESULTS The use of invasive size resulted in downstaging in 377 of 1704 patients (22%), with twice as many patients with p-Stage IA1 (IA1[i] versus IA1[t]: 389 [23%] versus 195 [11%]). However, outcomes were similar between the two groups (IA1[i] versus IA1[t]: 5-year cumulative incidence of recurrence, 11% versus 13%; 5-year lung cancer-specific cumulative incidence of death, 5% versus 7%). Prognostic discrimination by p-Stage(i) was better than by p-Stage(t) (C-index for p-Stage[i] versus p-Stage[t]: recurrence, 0.614 versus 0.593; lung cancer-specific death, 0.634 versus 0.621). CONCLUSIONS When invasive size, rather than total size, was used for the T descriptor, a larger number of patients were classified with a favorable prognosis (p-Stage IA1) and better prognostic discrimination of p-Stage I-IIA nonmucinous lung adenocarcinomas was achieved.

Abstract
Fetal adenocarcinoma is a rare disease. We report a case of fetal adenocarcinoma requiring differential diagnosis of metastatic lung tumor. A 75- year-old woman was pointed out a 8 mm tumor in the right lower lobe by chest computed tomography(CT) 6 month ago. Because the size of the tumor had been increasing for 6 months, she was hospitalized for surgery. Because of the tumor shape, we suspected that the tumor was metastatic lung tumor of hepatocellular carcinoma for which she had undergone hepatic arterial infusion chemotherapy and radiofrequency ablation. A right lower lobectomy with lymph node dissection was performed and pathological diagnosis was high-grade fetal adenocarcinoma, stage IV.
