Abstract
BACKGROUND Histopathology by pathologists is essential in the diagnosis of non-small cell lung cancer (NSCLC). However, auxiliary diagnostic procedures for malignant tumor have continued to evolve. Despite the poor prognosis of patients with NSCLC, the application of the latest procedures and technologies to the field of lung cancer has lagged. Mass spectrometry was used to detect trace amounts of peptides in human tissue with high accuracy. The aim of this study was to establish a method for diagnostic mass spectrometry to identify lymph node metastasis by detecting cytokeratin (CK)19, a useful biomarker in lung cancer. METHODS We collected 81 lymph nodes with positive expression of CK19 in patients who underwent radical surgical resection in the Department of Thoracic Surgery at Iwate Medical University between May 2020 and December 2022. An X500R instrument was used for sample analysis. A positive result for lymph node metastasis as the detection at least two product ions (FGPGVAFR and ILGATIENSR) from CK19 was defined. RESULTS Our study indicated a high diagnostic efficiency for mass spectrometry, with 87.5% sensitivity and 91.2% specificity. The mutual concordance of mass spectrometry methods and histopathological diagnosis was 90.1%. CONCLUSIONS Mass spectrometry offers high diagnostic accuracy and can be clinically applied to auxiliary diagnostic procedures for lymph node metastasis from NSCLC.

Abstract
OBJECTIVES Postoperative pulmonary complications (PPCs) provoke an extended hospital stay and increased postoperative mortality. Although several factors can cause PPCs, smoking is the only factor that can be adjusted within a short period of time preoperatively. However, the optimal period of smoking cessation to reduce the risk of PPCs remains unclear. METHODS A total of 1260 patients with primary lung cancer who underwent radical pulmonary resection between January 2010 and December 2021 were analyzed retrospectively. RESULTS We classified patients into two groups: non-smokers (patients who had never smoked) and smokers (patients who had ever smoked). The frequency of PPCs was 3.3% in non-smokers and 9.7% in smokers. PPCs were significantly less frequent in non-smokers than smokers (p < 0.001). When smokers were classified according to the duration of smoking cessation, the frequency of PPCs was significantly lower for a duration of 6 weeks or more than for less than 6 weeks (p < 0.001). In a propensity score analysis performed for 6 or more and less than 6 weeks' smoking cessation in smokers, the frequency of PPCs was significantly lower for smokers with 6 or more weeks' smoking cessation than for smokers with less than 6 weeks' smoking cessation (p = 0.002). A multivariable analysis identified less than 6 weeks' smoking cessation as a significant predictor of PPCs for smokers (odds ratio: 4.55, p < 0.001). CONCLUSIONS Smoking cessation for 6 or more weeks preoperatively significantly reduced the frequency of PPCs.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare disease that is considered an intermediate neoplasm, with the risk of recurrence and metastasis. Surgical treatment is the standard therapy for IMT, although there are only a few reports of surgery for lung metastasis of pulmonary IMT. We opine that surgical treatment might be effective not only for localized tumors, but also for cases of lung metastasis of IMT.

Abstract
Knowledge of the histologic type and primary origin of pulmonary tumors is essential when preparing a surgical strategy. Intraoperative diagnosis of hematoxylin and eosin (H&E)-stained frozen sections is the gold standard, but reliable pathology requires time-consuming immunohistochemistry (IHC) to distinguish among histological types/organ origins and to analyze molecular status. The aim of this study was to evaluate the clinical reliability of a new rapid-IHC technique for intraoperative diagnosis of pulmonary tumors. In total, 169 patients with undiagnosed pulmonary tumors were enrolled in a multicenter prospective observational study. At three institutes, pulmonary tumor samples were collected through core needle biopsy and/or surgery to determine surgical strategies. Using a new device for rapid IHC, we applied a high-voltage, low-frequency alternating current (AC) field, which mixes the available antibody as the voltage is switched on/off. Rapid IHC can provide tumor histologic type/origin diagnoses within 20 min, as opposed to the 3-6 h required for conventional IHC. No false diagnoses of malignancy were rendered in any of the cases when using simple H&E staining. With H&E staining alone, the overall definitive diagnosis rate, the rate of defined tumor origin, and the rate of determined histological type were 76.92%, 85.80%, and 90.53%, respectively. When rapid IHC was added, those rates were significantly improved to 88.76%, 94.67%, and 91.72%, respectively. By providing prompt and accurate intraoperative histological/molecular analysis, rapid IHC driven by AC mixing could serve as an effective clinical tool guiding the surgical strategy for undiagnosed pulmonary tumors.

Abstract
BACKGROUND Segmentectomy with curative intention is occasionally performed for early non-small cell lung cancer (NSCLC). However, a major problem has been pointed out, in that the rate of locoregional recurrence is higher after segmentectomy than after lobectomy. This study aimed to investigate differences in rates of lymph node metastasis between segment 6 and basal segment NSCLC as potential candidates for segmentectomy and to explore factors associated with locoregional recurrence of segmentectomy. METHODS We retrospectively analyzed 461 patients with lower lobe NSCLC who underwent segmentectomy or lobectomy with mediastinal lymph node dissection between 2011 and 2021. Among these, 122 patients with clinical N0 NSCLC, diameter ≤ 20 mm, and consolidation tumor ratio >0.5 were analyzed. RESULTS The 122 patients were divided into a segment 6 group (n = 51) and a basal segment group (n = 71). Frequency of lymph node metastasis was significantly higher in the segment 6 group (17.7%) than in the basal segment group (4.2%; p = 0.01). Metastases to lymph node station 7 were seen in five of 122 patients (4.1%). Hilar lymph node metastasis occurred in nine of 122 patients (7.4%). Notably, metastases to station 11, 11i and 11 s lymph nodes were the most frequent patterns for hilar lymph nodes (41.7%). CONCLUSIONS Station 11 lymph nodes are adjacent to the remaining lung segment or pulmonary artery in S6 segmentectomy or basal segmentectomy. Part of the NSCLC in segment 6 patients may thus be considered for lobectomy owing to the difficulty of complete dissection of station 11 lymph nodes.

Abstract
BACKGROUND Bleeding from the pulmonary artery (PA) can be fatal in video-assisted thoracoscopic surgery (VATS) for lung cancer. We evaluated intraoperative PA injury and assessed precautions for thoracoscopic anatomic pulmonary resection. METHODS We retrospectively analyzed a total of 1098 patients who underwent radical surgery for lung cancer utilizing complete VATS from January 2010 to December 2021. RESULTS A total of 16 patients (1.5%) had PA injury during VATS, while hemostasis was performed by conversion to thoracotomy in eight patients (50.0%). Although there was a significantly greater operation time and blood loss for patients in the PA injury group (318.4 vs. 264.9 min, p = 0.001; 550.3 vs. 60.5 g, p ≤ 0.001, respectively), there was no significant different for the chest tube insertion duration and length of postoperative hospital stay (4.9 vs. 7.8 days, p = 0.157; 10.6 vs. 9.9 days, p = 0.136, respectively). There was a significant difference observed for the surgical procedure related to the left upper lobectomy in the PA injury group (43.8 vs. 18.8%, p = 0.012), with the primary causative PA determined to be the left anterior segmental PA (A3 ) (31.3%). CONCLUSIONS VATS is both feasible and safe for lung cancer treatment provided the surgeon performs appropriate hemostasis, although fatal vascular injury could potentially occur during VATS. Surgeons need to be aware of the pitfalls regarding PA dissection management.

Abstract
Background Rapid intraoperative diagnosis for unconfirmed pulmonary tumor is extremely important for determining the optimal surgical procedure (lobectomy or sublobar resection). Attempts to diagnose malignant tumors using mass spectrometry (MS) have recently been described. This study evaluated the usefulness of MS and artificial intelligence (AI) for differentiating primary lung adenocarcinoma (PLAC) and colorectal metastatic pulmonary tumor. Methods Pulmonary samples from 40 patients who underwent pulmonary resection for PLAC (20 tumors, 20 normal lungs) or pulmonary metastases originating from colorectal metastatic pulmonary tumor (CRMPT) (20 tumors, 20 normal lungs) were collected and analyzed retrospectively by probe electrospray ionization‐MS. AI using random forest (RF) algorithms was employed to evaluate the accuracy of each combination. Results The accuracy of the machine learning algorithm applied using RF to distinguish malignant tumor (PLAC or CRMPT) from normal lung was 100%. The algorithms offered 97.2% accuracy in differentiating PLAC and CRMPT. Conclusions MS combined with an AI system demonstrated high accuracy not only for differentiating cancer from normal tissue, but also for differentiating between PLAC and CRMPT with a short working time. This method shows potential for application as a support tool facilitating rapid intraoperative diagnosis to determine the surgical procedure for pulmonary resection.

Abstract
Background Completion lobectomy after wedge resection is occasionally performed when final histopathology shows an unexpected primary lung cancer even though the primary lesion has already been resected. The objective of this study was to assess the necessity of completion lobectomy after wedge resection for ≤20 mm non-small cell lung cancer (NSCLC). Methods Between 2006 and 2016, a total of 112 patients with NSCLC underwent wedge resection in our department. After exclusions, 40 patients were analyzed. Of these, 17 patients underwent completion lobectomy and 23 patients underwent wedge resection alone. Age, sex, tumor size, histology, other malignant diseases and final surgical procedure were used as prognostic variables. Survival analyses were confirmed using the Kaplan-Meier method and log-rank test. Results Median follow-up was 70.4 months. No significant difference in 5-year overall survival (OS) and relapse-free survival (RFS) were seen in patients who underwent wedge resection alone compared to the completion lobectomy group (OS: 72.6% vs. 62.5%, P=0.34; RFS: 64.2% vs. 50.0%, P=0.35). Multivariate analysis identified age (>65 years old) and male sex as independent prognostic factors for OS and RFS. Conclusions Completion lobectomy after wedge resection did not impact OS or RFS compared with wedge resection alone in patients with ≤20 mm NSCLC. These findings suggested that selected patients may not require resection of the remaining lobe or lymph node dissection after initial wedge resection.

Abstract
Low‐grade fibromyxoid sarcoma (LGFMS) is a rare sarcoma subtype that most commonly arises in young adults. This tumor typically presents in the deep soft tissues of the proximal extremities or trunk as a painless mass. Although the most common site of LGFMS metastasis is the lung, it is rarely the primary site. Here, we report a case of primary pulmonary LGFMS. A 22‐year‐old asymptomatic man was referred to our hospital for investigation of a lung mass that had been discovered incidentally. Computed tomography (CT) showed a well‐defined mass 4.0 cm in diameter in the upper lobe of the right lung. Malignancy was suggested by focal uptake of 18F‐fluorodeoxyglucose positron‐emission tomography (18‐FDG‐PET). Following surgery, postoperative histological analysis of the resected specimen demonstrated LGFMS based on histological and immunohistological findings. In particular, mucin 4 showed diffuse positivity in the spindle‐shaped tumor cells. In conclusion, LGFMS can arise in the lungs, and physicians should consider this entity as a differential diagnosis for solitary lung mass in young adults.

Abstract
Background Primary spontaneous pneumothorax (PSP) occurs more frequently in young, tall men, with approximately 10,000 times video-assisted thoracoscopic surgery (VATS) annually in Japan is undergoing for surgical treatment. The underlying mechanisms remain unclear, but several reports have suggested correlation with weather conditions. This study aimed to evaluate the relationship between onset of PSP and changes in weather. Methods We retrospectively analyzed data from 112 patients who underwent VATS for PSP in Iwate, Japan from 1 January 2010 to 14 June 2020. Of the 3,818 days in this study period, the day on which the patient became aware of symptoms was classified as the PSP onset day (n=112), and all others were classified as PSP non-onset day (n=3,706). Meteorological data were collected from airbase station using an online source for the same place and same time. Logistic regression modeling was used to obtain predicted risks for the onset of PSP with respect to weather conditions. Results Among the meteorological parameters, significant differences were mainly found at 2 days before onset for increasing average temperature [odds ratio (OR): 1.97, P=0.018], minimum temperature (OR: 1.97, P=0.018), average humidity (OR: 1.58, P=0.043), and decreased the sunshine time (OR: 2.26, P=0.012). No significant difference was observed in atrophic pressure at 2 days before onset. Conclusions Onset of PSP may correlate with the increased temperature and humidity, seen with an approaching of warm front.

Abstract
OBJECTIVES Diffusion capacity of the lung for carbon monoxide (DLCO) is a useful value for perioperative risk assessment of non-small cell lung cancer (NSCLC). The percentage of the predicted DLCO (%DLCO: DLCO/predicted DLCO × 100) is often evaluated by setting cutoff values as in the clinical field, but several formulae are available for calculating the predicted DLCO, and the %DLCO thus varies depending on the formula used to predict DLCO. We examined differences in %DLCO calculated using several commonly used prediction formulae. METHODS A total of 490 eligible patients who underwent completed video-assisted thoracoscopic surgery (c-VATS), especially radical pulmonary lobectomy, for NSCLC were analyzed retrospectively. Predicted DLCO was calculated using the prediction formulae described by Burrows, Nishida, Cotes, and Kanagami, then the relationships with postoperative complications were evaluated. RESULTS The %DLCO from Nishida's formula was two-thirds the value of that from Burrows' (p < 0.05). On logistic regression analysis, predicted postoperative %DLCO (ppo-DLCO) based on the formulae of Burrows, Cotes and Kanagami were independent factors related to postoperative pulmonary complications after c-VATS lobectomy for NSCLC (odds ratios 2.46, 1.79 and 2.33, p = 0.005, 0.043 and 0.009, respectively). CONCLUSIONS The %DLCO is a useful index for surgical risk assessment of c-VATS lobectomy for NSCLC, while the results differ markedly between individual prediction formulae. Specification of the formula used is necessary in cases considering risk evaluations.

Abstract
Background This study aimed to observe the association between trace element concentrations in lung tissue from lung adenocarcinoma cancer (LADC) patients and mutations in the epidermal growth factor receptor (EGFR) and KRAS genes. Methods LADC patients who had undergone lung resection were included in this study. Furthermore, twenty patients without lung cancer were included in this study as the control group. Samples were separately collected from both tumor and peritumor tissues. The mutational status was assessed for EGFR mutations, ALK rearrangements and KRAS mutations. Based on these analyses, patients were grouped into three groups: EGFR mutation, KRAS mutation and wild-type groups. The concentrations of various trace elements in the lung tissues were measured by a particle-induced X-ray emission (PIXE) system, and the results were analyzed for statistical significance. Results A total of 110 LADC patients were included in this study. The median age was 70 years, and 60% of the participants were female. Moreover, 18% and 20% of patients were EGFR- and KRAS-positive, respectively. Thirty-two trace elements were measured, and 18 trace elements were detectable. The concentrations of Fe, Co, Ni, Cu, Zn and Br were significantly higher in the KRAS mutation and wild-type groups than in the control group regardless of whether the samples were from tumor or peritumor tissues. For these 6 trace elements, the concentrations were significantly higher in smokers than in non-smokers. Considering the effect of smoking, differences in the trace element concentrations between each mutational group remained. Conclusions Trace elements in the lung may play a role in development of LADC in both smokers and never-smokers. However, prospective studies with larger sample sizes are needed to support this hypothesis.

Abstract
Background Air leakage is a common complication after pulmonary wedge resection. The aim of this study was to evaluate the effect of staple line reinforcement in reducing air leakage after pulmonary wedge resection. Methods A retrospective analysis was performed on patients who underwent pulmonary wedge resection. The patients were classified into 2 groups; the Stapler with polyglycolic acid sheet was used for the reinforced and the Stapler without polyglycolic acid sheet was used for the non-reinforced group. The patients were matched one-to-one based on a propensity score that comprised several patient characteristics. A propensity score-matched analysis was performed to compare patient outcomes. Results A total of 291 patients who met the inclusion criteria were investigated. There were 165 in the reinforced group and 126 patients in the non-reinforced group. Propensity score analysis generated 104 matched pairs of patients in both the reinforced and the non-reinforced groups. The rate of non-placement of chest tube was significantly higher in the reinforced group than in the non-reinforced group (61.5% vs. 36.5%; P<0.001). The rate of postoperative air leakage was higher in the non-reinforced group than in the reinforced group (13.5% vs. 1.9%, P<0.001). On logistic regression analysis, not using the reinforcement device was one of the independent factors related to pulmonary air leakage after pulmonary wedge resection (OR: 8.58, P<0.001). Conclusions The use of the Stapler with polyglycolic acid sheet during pulmonary wedge resection increased the rate of intraoperative chest tube removal and reduced the rate of postoperative air leakage.

Abstract
Background Although postoperative pneumonia after radical surgery for non-small cell lung cancer (NSCLC) carries a mortality risk, the duration of postoperative prophylactic antibiotics against pneumonia has not been elucidated. This study aimed to evaluate the influence of the duration of prophylactic antibiotics on postoperative pneumonia following radical surgery for NSCLC in patients who received antibiotics intraoperatively (short period) and in those who received antibiotics both intraoperatively and postoperatively (long period). Methods A total of 477 patients who underwent radical lobectomy for NSCLC were analyzed retrospectively. Propensity score analysis generated two matched pairs of 152 patients in both the short and long period groups. Results After propensity score matching, the incidence of postoperative pneumonia following pulmonary lobectomy was significantly less in the long period group than in the short period group (3.9% vs. 16.4%, P<0.001). On logistic regression analysis, short period of prophylactic antibiotic administration was the independent risk factor for postoperative pneumonia (odds ratio: 6.82, P<0.001). Conclusions Prophylactic antibiotic administration in both the intraoperative and postoperative periods reduced the incidence of pneumonia after pulmonary lobectomy for NSCLC.

Abstract
PURPOSE In recent years, several reports have noted that the specific coagulation mode called "soft coagulation" with modern electrosurgical tools offers superior hemostasis. The "suction ball coagulation" (SBC) device, which can achieve hemostasis using a soft coagulation mode and simultaneous suction, has been developed as a next step. This study aimed to evaluate the hemostatic effects of SBC in comparison to a conventional soft coagulation device (non-SBC) in video-assisted thoracoscopic surgery (VATS) for patients with non-small cell lung cancer (NSCLC). METHODS This study retrospectively analyzed 351 patients who underwent complete VATS lobectomy for NSCLC. A propensity score analysis generated matched pairs from the patients in the SBC and non-SBC groups (119 patients each). RESULTS After propensity score matching, the bleeding volume during surgery in the SBC group (27.0 g) was significantly less than that in the non-SBC group (42.0 g, p < 0.001). No significant difference was seen in the frequency of postoperative complications. A logistic regression analysis identified the non-use of SBC as an independent risk factor for greater intraoperative blood loss during complete VATS lobectomy (odds ratio 3.14, p < 0.001). CONCLUSIONS SBC was safe for complete VATS lobectomy in patients with NSCLC, and the use of this device was associated with significantly decreased intraoperative blood loss.

Abstract
Most malignant mesotheliomas (MPMs) frequently show activated forms of Yes-associated protein 1 (YAP1) and transcriptional co-activator with PDZ-binding motif (TAZ), which transcriptionally regulates the receptor for hyaluronic acid-mediated motility (RHAMM). As RHAMM is involved in cell migration and invasion in various tumors, we speculated that hyaluronic acid (HA) in pleural fluid might affect the progression of mesothelioma by stimulating cell migration and invasion through RHAMM. The level of RHAMM expression was decreased by YAP1/TAZ knockdown, and conversely increased by forced expression of the active form of YAP1, suggesting that RHAMM was regulated by YAP1/TAZ in MPM cells. Cell migration and invasion were also decreased by YAP1/TAZ or RHAMM knockdown. Notably, HA treatment increased cell motility and invasion, and this was abolished by RHAMM knockdown, suggesting that HA may augment local progression of MPM cells via RHAMM. Furthermore, treatment with fluvastatin, which regulates RHAMM transcription by modulating YAP1/TAZ activity, decreased the motility and invasion of MPM cells. Collectively, these data suggest that HA is an “unfavorable” factor because it promotes malignancy in mesothelioma and that the YAP1/TAZ-RHAMM axis may have potential value as a therapeutic target for inhibition of disease progression in MPM.

Abstract
BACKGROUND Angiogenesis in the alveolar septa is thought be a critical factor in pulmonary emphysema. Angiomotin-like protein 1 (AmotL1) is involved in angiogenesis via regulating endothelial cell function. However, the role of AmotL1 in the pathogenesis of pulmonary emphysema has not been elucidated. The objective of this study is to evaluate the expression of AmotL1 in lung tissues from a murine model with emphysema, as well as from patients with chronic obstructive pulmonary disease (COPD). Furthermore, we analyzed the regulation of AmotL1 expression by TNF-α and IFN-γ in endothelial cells in vitro. METHODS Nrf2 knockout mice were exposed to cigarette smoke (CS) for 4 weeks, and the down-regulated genes affecting vascularity in the whole lung were identified by microarray analysis. This analysis revealed that the mRNA expression of AmotL1 decreased in response to CS when compared with air exposure. To confirm the protein levels that were indicated in the microarray data, we determined the expression of AmotL1 in lung tissues obtained from patients with COPD and also determined the expression of AmotL1, NFκB and IκBα in cultured normal human lung microvascular endothelial cells (HLMVECs) that were stimulated by TNF-α and IFN-γ. RESULTS We found that the number of AmotL1-positive vessels decreased in the emphysema lungs compared with the normal and bronchial asthmatic lungs. IFN-γ pretreatment diminished the TNF-α-induced AmotL1 in the cultured HLMVECs by blocking the degradation of IκBα. CONCLUSIONS These results suggested that IFN-γ exhibits anti-angiogenesis effects by regulating the expression of TNF-α-induced AmotL1 via NFκB in emphysema lungs.
