Abstract
Background The standard adjuvant chemotherapy regimen for completely resected pathological stage II/IIIA non-small cell lung cancer (NSCLC) is four courses of cisplatin plus vinorelbine. However, the continuity and toxicity of cisplatin-based regimens remain problematic. Conversely, carboplatin-based chemotherapy is a less toxic and more tolerable regimen for various stages of NSCLC. In particular, the efficacy and tolerability of carboplatin plus S-1 in advanced NSCLC were confirmed by previous pivotal studies such as the LETS trail. Therefore, this phase II study assessed the feasibility, safety, and usefulness of carboplatin plus S-1 followed by maintenance S-1 as an adjuvant treatment. Methods In this single-arm, multicenter phase II study, 40 patients who previously underwent complete resection of NSCLC were enrolled from November 2013 to January 2015. The chemotherapy protocol was four cycles of carboplatin (AUC 5 on day 1) and oral S-1 (80 mg/m2 every other day from days 1 to 21) followed by oral S-1 (80 mg/m2 every other day for 48 weeks). The primary endpoint was the treatment completion rate, and the secondary endpoints were adverse events and 2-year recurrence-free survival. Results The treatment completion rate of the planned schedule was as low as 30.0% (90% confidence interval: 40.3–63.0%). The reasons for adjuvant chemotherapy discontinuation were adverse events, refusal, tumor recurrence, and other reasons in 13, 6, 10, and 2 patients, respectively. The 2-year progression-free survival rate was 66.7% among patients who completed maintenance chemotherapy. There were no treatment-related deaths, and most adverse events were less than grade 3. Conclusions Carboplatin plus S-1 followed by S-1 maintenance for 1 year in the adjuvant treatment of NSCLC was not tolerable, although most adverse events were not severe. However, patients who can fully complete the regimen might experience clinical benefit.

Abstract
The need for effective treatment of KRAS‑mutant lung cancer is an emerging issue. Rho GTPase‑activating protein 35 (ARHGAP35) is reported to be a possible molecular target for lung adenocarcinoma. We investigated the effect of long‑term ARHGAP35 suppression on the proliferation, migration and molecular dynamics of lung adenocarcinomas harboring KRAS and EGFR gene mutations. Lung adenocarcinoma cell lines A549 (KRAS‑mutant) and PC9 and H1975 (EGFR‑mutants) were used, and ARHGAP35 knockdown was carried out using puromycin. Cell viability, migration and molecular dynamics were assayed 1 month after introducing small hairpin RNA. The compensatory upregulated mechanism was screened by western blotting and confirmed by a specific inhibitor. Finally, we tested the effects of cosuppression of the SRC/ARHGAP35 axis and the identified pathway in vitro. ARHGAP35 suppression was attenuated by long‑term knockdown of the target genes. Compensatory mechanisms by SRC and STAT3 caused attenuation in A549 cells. After long‑term ARHGAP35 knockdown, both A549 and PC9 cells were more sensitive to treatment with a STAT3 inhibitor. The suppressive effect of ARHGAP35 knockdown on migration was sustained, but only modest, in all cell lines. Synergistic and strong growth inhibition was observed with concomitant use of an SRC inhibitor and a STAT3 inhibitor in A549 cells. STAT3 activation compensated for ARHGAP35 knockdown in lung adenocarcinoma with the KRAS mutation. Moreover, cosuppression of the STAT3 pathway and SRC/ARHGAP35 axis may be an effective strategy for treating lung adenocarcinoma, especially in the presence of a KRAS mutation.

Abstract
Immunohistochemistry for several neurochemical substances was performed on the human incisive papilla and other oral structures. Sodium channel alpha subunit 7 (SCN7A) protein-immunoreactive (IR) Schwann cells and protein gene product 9.5 (PGP 9.5)-IR nerve fibers made nerve plexuses beneath the epithelium of the palate, including the incisive papilla, tongue, and lip. SCN7A immunoreactivity could also be detected in lamellated and nonlamellated capsules of corpuscle endings. Lamellated SCN7A-IR corpuscle endings were mostly restricted to the mucous and cutaneous lips. These endings had thick and spiral-shaped PGP 9.5-IR axons without ramification. Nonlamellated SCN7A-IR corpuscle endings were most numerous in the incisive papilla among the oral regions. On the basis of axonal morphology, the nonlamellated endings were divided into simple and complex types. PGP 9.5-IR terminal axons in the simple type ran straight or meandered with slight ramification, whereas those in the complex type were densely entangled with abundant ramification. Substance P (SP)-, calcitonin gene-related peptide (CGRP)-, and transient receptor potential cation channel subfamily V member 2 (TRPV2)-IR varicose fibers were rarely seen beneath the epithelium of oral structures. The present study indicates that the human incisive papilla has many low-threshold mechanoreceptors with nonlamellated capsules. SP-, CGRP-, and TRPV2-containing nociceptors may be infrequent in the incisive papilla and other oral regions.

Abstract
The pulmonary extraction from a brain-dead donor is one of the important elements for the success of lung transplantation, but the current scarcity of practical training opportunities is a major problem. We performed a simulation of the donor surgery of multiple organs using a pig with other extraction teams to provide more training opportunities. The effectiveness of this simulation lies in its potential to improve the surgical procedure;furthermore, it may solve problems associated with communicating with other extraction teams. However, it is difficult to judge whether the donor lung is suitable for transplantation, as it would be inappropriate to use such a lung for simulation in training. Since this simulation system is considered to be effective to solve various problems in the current donor surgery, it should be available more frequently to improve a technical level of the donor surgery and to aid surgeons in the rapid implementation of next-generation techniques.

Abstract
Lung cancer patients with cardiovascular complications often require antithrombotic therapy. In this study, we discuss the present conditions and future problems associated with the perioperative management of such patients. We examined 36 lung cancer patients undergoing surgery who received antithrombotic therapy for cardiovascular complications. Twenty-one patients were administered unfractionated heparin in the perioperative period (heparin group). Fifteen patients were not administered unfractionated heparin in the perioperative period (no-heparin group). No significant intergroup differences were observed in operating time, intraoperative blood loss, duration of chest tube placement, and the number of hospitalization days. However, 2 serious cases of thromboembolism developed after surgery. One was a case of pulmonary thromboembolism and the other was one of superior mesenteric artery thromboembolism. These results suggest that the appropriate perioperative usage of heparin enables the standard surgical treatment of lung cancer patients with cardiovascular complications. We recommend the use of low-molecular-weight heparin or low-dose unfractionated heparin as the antithrombotic agent after lung cancer surgery.

Abstract
BACKGROUND To evaluate the effects of administering chemotherapy following surgery, or following surgery plus radiotherapy (known as adjuvant chemotherapy) in patients with early stage non-small cell lung cancer (NSCLC),we performed two systematic reviews and meta-analyses of all randomised controlled trials using individual participant data. Results were first published in The Lancet in 2010. OBJECTIVES To compare, in terms of overall survival, time to locoregional recurrence, time to distant recurrence and recurrence-free survival:A. Surgery versus surgery plus adjuvant chemotherapyB. Surgery plus radiotherapy versus surgery plus radiotherapy plus adjuvant chemotherapyin patients with histologically diagnosed early stage NSCLC.(2)To investigate whether or not predefined patient subgroups benefit more or less from cisplatin-based chemotherapy in terms of survival. SEARCH METHODS We supplemented MEDLINE and CANCERLIT searches (1995 to December 2013) with information from trial registers, handsearching relevant meeting proceedings and by discussion with trialists and organisations. SELECTION CRITERIA We included trials of a) surgery versus surgery plus adjuvant chemotherapy; and b) surgery plus radiotherapy versus surgery plus radiotherapy plus adjuvant chemotherapy, provided that they randomised NSCLC patients using a method which precluded prior knowledge of treatment assignment. DATA COLLECTION AND ANALYSIS We carried out a quantitative meta-analysis using updated information from individual participants from all randomised trials. Data from all patients were sought from those responsible for the trial. We obtained updated individual participant data (IPD) on survival, and date of last follow-up, as well as details of treatment allocated, date of randomisation, age, sex, histological cell type, stage, and performance status. To avoid potential bias, we requested information for all randomised patients, including those excluded from the investigators' original analyses. We conducted all analyses on intention-to-treat on the endpoint of survival. For trials using cisplatin-based regimens, we carried out subgroup analyses by age, sex, histological cell type, tumour stage, and performance status. MAIN RESULTS We identified 35 trials evaluating surgery plus adjuvant chemotherapy versus surgery alone. IPD were available for 26 of these trials and our analyses are based on 8447 participants (3323 deaths) in 34 trial comparisons. There was clear evidence of a benefit of adding chemotherapy after surgery (hazard ratio (HR)= 0.86, 95% confidence interval (CI)= 0.81 to 0.92, p< 0.0001), with an absolute increase in survival of 4% at five years.We identified 15 trials evaluating surgery plus radiotherapy plus chemotherapy versus surgery plus radiotherapy alone. IPD were available for 12 of these trials and our analyses are based on 2660 participants (1909 deaths) in 13 trial comparisons. There was also evidence of a benefit of adding chemotherapy to surgery plus radiotherapy (HR= 0.88, 95% CI= 0.81 to 0.97, p= 0.009). This represents an absolute improvement in survival of 4% at five years.For both meta-analyses, we found similar benefits for recurrence outcomes and there was little variation in effect according to the type of chemotherapy, other trial characteristics or patient subgroup.We did not undertake analysis of the effects of adjuvant chemotherapy on quality of life and adverse events. Quality of life information was not routinely collected during the trials, but where toxicity was assessed and mentioned in the publications, it was thought to be manageable. We considered the risk of bias in the included trials to be low. AUTHORS' CONCLUSIONS Results from 47 trial comparisons and 11,107 patients demonstrate the clear benefit of adjuvant chemotherapy for these patients, irrespective of whether chemotherapy was given in addition to surgery or surgery plus radiotherapy. This is the most up-to-date and complete systematic review and individual participant data (IPD) meta-analysis that has been carried out.

Abstract
BACKGROUND To compare lung cancer detection rate by sputum cytology, we need some assurance that the estimates do not vary widely if different observers evaluate the same specimens. The aim of this study was to determine inter-rater agreement of sputum cytology diagnoses. METHODS Slides of sputum cytology from 150 subjects were selected from a pool of slides held by six of the laboratories that had participated in a population-based lung cancer screening program over the last ten years in Japan. The cytotechnologists in these laboratories had considerable experience with sputum cytology. Each case was re-evaluated six times. Cases that were diagnosed as the same category by all six laboratories were selected as consensus cases to serve as standardized sputum cytology cases. Thirty-seven cytotechnologists with various levels of experience in sputum cytology then re-evaluated these consensus cases. Inter-rater agreement was calculated by kappa statistics including Fleiss' kappa. RESULTS All pairs of interlaboratory agreement for the 150 cases showed statistically significant kappa values, most pairs showing substantial agreement. Fleiss' kappa value across the six laboratories was 0.5. Fourteen cases were identified as the consensus cases, and the agreement among observers with less experience of sputum cytology showed significantly lower than the agreement among those with considerable experience (Fleiss' kappa value 0.27 vs. 0.45, P < 0.05). Moreover, cytotechnologists with less experience under-diagnosed the slides significantly more often than those with considerable experience. CONCLUSION When the observers have considerable experience with sputum cytology, inter-observer agreement is good.

Abstract
BACKGROUND Purely localized, oligometastatic, and widely metastatic tumors are likely to require different therapeutic strategies. Although surgical procedures for isolated pulmonary, brain, or adrenal metastases from lung cancer have been extensively evaluated, most data are from retrospective studies; accordingly, we conducted a prospective multicenter trial. METHODS Patients were eligible if they had previously untreated clinical T1-2N0-1 lung cancer with single-organ metastasis, or single-organ metachronous metastasis after complete resection of pathologic T1-2N0-1 lung cancer. Metastatic lesions were classified into three groups: group A included metastasis in single organs other than brain or lung; group B included synchronous brain metastasis; and group C included pulmonary metastasis. The treatment intervention was surgical resection of metachronous metastasis or of both synchronous metastasis and primary lung cancer. RESULTS From December 2002 through June 2011, 36 patients were enrolled. Two patients were ineligible, and the remaining 34 were analyzed; 6 (18%) had a benign lesion and no metastasis, 5 patients (15%) underwent incomplete resection of primary lung cancer, and 20 patients (59%) underwent complete resection of both primary lung cancer and metastasis. The 5-year survival rate for these 20 cases was 44.7%. CONCLUSIONS Clinical T1-2N0-1 lung cancer with a single-organ metastatic lesion was a good candidate for surgical resection. A 5-year survival rate of about 40% can be expected, which could be comparable with that for stage II non-small cell lung cancer.

Abstract
BACKGROUND Eukaryotic elongation factor 1 alpha-2 (eEF1A2) has been recently shown to be a putative oncogene of lung cancer. MATERIALS AND METHODS We analyzed the expression and prognostic significance of eEF1A2 in 69 primary non-small cell lung cancer (NSCLC) cases. We also suppressed eEF1A2 expression using RNA interference and then analyzed cell proliferation, migration and invasion of five adenocarcinoma cell lines. RESULTS eEF1A2 protein expression was positive in 84.1%. Negative immunostaining for eEF1A2 was shown to be an independent prognostic factor and significantly correlated with lymph node metastasis. There was no significant correlation between eEF1A2 protein and mRNA expression levels. Among the five examined cell lines, transfection of eEF1A2 siRNA inhibited cell migration in only one cell line while it did not change cell proliferation and invasion. CONCLUSION Negative immunostaining of eEF1A2 predicted for poor prognosis of NSCLC. The mechanism of this result could not be elucidated by cell proliferation, migration and invasion assays.

Abstract
We present here our institutional review of surgical treatment for the chest wall tumors. Chest wall resections were performed on 80 patients, and subsequent chest wall reconstructions were performed on 45 patients. Primary malignant tumors in the chest wall required more extensive rib resections combined with the neighboring structures such as the sternum and the vertebral bones than benign or metastatic/recurrent tumors did. Postoperative mortality and morbidity occurred in 5 patients who underwent the sternal resection and the rib resection combined with the vertebral bodies. Primary malignant tumors in the chest wall are sarcomas originating from the bones, the cartilage tissues, and the soft tissues of the chest wall. We general thoracic surgeons may not have expertise in treating sarcomas,because primary malignant chest wall tumors are rare and a single institution has limited experiences in surgical treatment of such tumors. We should be aware that a surgical margin of primary malignant chest wall tumors is important to achieve excellent local control and better prognosis. We recommend cooperation with an orthopedic oncologist who is experienced with treating sarcomas. Not only preoperative planning but also intraoperative evaluation for the surgical margin with orthopedic oncologists is necessary for better surgical outcome.

Abstract
AIM Although angiogenesis plays an important role in the invasion and metastasis of solid tumors, very few anti-angiogenetic drugs have been developed. Reexamining the anti-angiogenetic effects of existing drugs such as Thalidomide is another possible strategy for drug discovery. Irsogladine maleate (IM) is a drug invented to treat gastric ulcers; however, several reports have shown that IM also exerts anti-angiogenetic effects in vitro, in vivo and in humans. In order to elucidate whether treatment with IM would improve the prognoses of patients with resected lung cancer, we conducted a randomized trial. METHODS In the control group, uracil-tegafur (250 mg/m2/day) was administered for two years to patients with resected stage IB - IIIA lung cancer, and no adjuvant therapy was administered to those with stage IA disease. In the study group, IM (4 mg/body/day) was additionally administered for two years. RESULTS No significant differences were observed in the major prognostic factors among 305 eligible patients between the study and control groups. Adverse effects were minimal. The overall survival of the patients in the study and control groups were not statistically different. When the analysis was stratified by regimen, among the patients with resected stage IA disease, disease-specific survival in the study group was slightly higher than that in the control group; however, the difference was not significant (p=0.07). CONCLUSION Although it could not be proven that IM improves the prognoses of resected lung cancer patients, IM might have some effect on resected stage IA disease, and another trial should be conducted.

Abstract
Overcoming acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR‑TKIs) is an emerging issue in lung cancer treatment. We report evidence that a GTPase-activating protein, p190-A RhoGAP (p190), is a potential molecular target for the treatment of lung adenocarcinoma. We documented inhibition of phosphorylation of p190 by EGFR-TKI treatment in lung adenocarcinoma cell lines. Small interfering RNA-mediated knockdown of p190 leads lung adenocarcinoma cells to growth suppression and to inhibition of invasion/migration through inducing cell cycle arrest but not apoptosis. These findings were observed not only in EGFR-TKI-sensitive cells but also in EGFR-TKI-resistant cells; even in cell lines harboring K-ras mutations. The mechanism of this inhibitory effect on growth and invasion/migration was Ras inactivation through disrupting the p190-A RhoGAP/p120RasGAP complex. In addition, a high level of p190 mRNA expression was observed in majority of surgically obtained tissue from lung adenocarcinoma patients. Overexpression of p190 mRNA associated with poor disease-free survival. The results suggest that overexpression of p190 mRNA may be involved in the carcinogenesis of lung adenocarcinoma. These findings indicate that p190 is a possible molecular target for treatment of lung adenocarcinoma.

Abstract
Background: Lung adenocarcinoma (LADCA) patients with epidermal growth factor receptor (EGFR) mutations are in general associated with relatively high clinical response rate to EGFR-tyrosine kinase inhibitors (TKIs) but not all responded to TKI. It has therefore become important to identify the additional surrogate markers regarding EGFR-TKI sensitivity. Methods: We first examined the effects of EGFR-TKIs, gefitinib and erlotinib, upon cell proliferation of lung adenocarcinoma cell lines. We then evaluated the gene profiles related to EGFR-TKI sensitivity using a microarray analysis. Results of microarray analysis led us to focus on carcinoembryonic antigen-related cell adhesion molecule (CEACAM) family, CEACAM 3, 5, 6, 7, and 19, as potential further surrogate markers of EGFR-TKI sensitivity. We then examined the correlation between the status of CEACAM 3, 5, 6, 7, and 19 immunoreactivity in LADCA and clinicopathological parameters of individual cases. Results: In the cases with EGFR mutations, the status of all CEACAMs examined was significantly higher than that in EGFR wild-type patients, but there were no significant differences in the status of CEACAMs between TKI responder and nonresponder among 22 patients who received gefitinib therapy. However, among 115 EGFR mutation-negative LADCA patients, both CEACAM6 and CEACAM3 were significantly associated with adverse clinical outcome (CEACAM6) and better clinical outcome (CEACAM3). Conclusion: CEACAMs examined in this study could be related to the presence of EGFR mutation in adenocarcinoma cells but not represent the effective surrogate marker of EGFR-TKI in LADCA patients. However, immunohistochemical evaluation of CEACAM3/6 in LADCA patients could provide important information on their clinical outcome.

Abstract
Early central airways lung cancer accounts for very small percentage of all lung cancers. Given this fact, it is much difficult to carry out a prospective randomized comparative clinical trial. Even retrospective studies can offer important information. Early central airways lung cancer is usually detected by sputum cytology. If sputum cytology shows atypical epithelial cells implying malignancy, the next thing we have to do is bronchoscopy. Both autofluorescence bronchoscopy and white light bronchoscopy were superior to white light bronchoscopy alone in detecting this type of lung cancer. Natural history of this cancer showed about the two-thirds of the patients die from original disease within 10 years. If the tumor length is 10 mm or less, photodynamic therapy is a first-line modality. After photodynamic therapy, a 5-year overall survival of about 80 % and a 10-year overall survival of 70 % can be expected. If a cancer does not meet the criteria for photodynamic therapy, surgical resection is recommended, and 5-year overall survival of about 80 % can be expected. Segmentectomy should be considered because of pulmonary function preservation if a tumor is located at segmental bronchi or beyond it. The frequency of multicentricity is high. Treatment strategy for subsequent primary lung cancer is an important key for the prognosis of patients with treated early central airways lung cancer. Surgical resection is still the most reliable treatment of subsequent primary lung cancer, except for in situ or microinvasive carcinoma located centrally, which could be cured by photodynamic therapy.

Abstract
p62/SQSTM1 is a selective substrate of autophagy, and aberrant accumulation of p62 has been observed in various pathological conditions. To understand the roles p62 plays in non-small-cell lung cancer (NSCLC), we carried out immunohistochemical analyses of p62 expression in a cohort of patients with annotated clinicopathological data. As analyses of murine and human hepatocellular carcinomas suggested a correlation between p62 and Nrf2 accumulations, we also examined NRF2 expression in the same cohort. The expression of NRF2 and p62 was examined by immunohistochemical methods in 109 NSCLC cases, which included patients with adenocarcinoma (n = 72), squamous cell carcinoma (n = 31), and large cell carcinoma (n = 6). Accumulation of NRF2 and p62 was detected in 34% and 37% of NSCLC patients, respectively. The accumulations of p62 and NRF2 did not correlate with each other, but both were associated with worse lung cancer-specific survival (P = 0.0003 for NRF2; P = 0.0130 for p62). NRF2 status had an impact on NSCLC prognosis irrespective of histology types, but p62 status did so particularly in adenocarcinoma (P = 0.037). Multivariate analysis indicated that positive immunoreactivities of NRF2 and p62 were both independent factors predicting worse lung cancer-specific survival (P < 0.0001 for NRF2 and P = 0.04 for p62). This study revealed that both NRF2 and p62 are independent prognostic factors for NSCLC. The prognostic impact of p62 status was pronounced in adenocarcinoma patients, suggesting that molecular mechanisms underlying cancer evolution differ between adenocarcinoma and squamous cell carcinoma.

Abstract
Ninety-three patients with completely resected peripheral non-small cell lung cancer, clinically diagnosed 2 cm or less in diameter, were retrospectively reviewed. Their preoperative computed tomography (CT) and positron emission tomography (PET) findings, carcinoembryonic antigen (CEA) values, clinico-pathological features and postoperative outcomes were analysed. Ground-glass opacity (GGO) ratio( soft tissue density area of the tumor/maximum area of the tumor in diameter) was measured. The overall survival rate at 3 years was 93.3% and the relapse-free survival rate at 3 years was 89.4% with a median follow-up period of 38.5 months. Patients with GGO ratio 0.25 or less had no lymph node (LN) involvement nor lymph vascular invasion. Only 2 of them (8%) had vascular invasion. Fisher's exact probability test revealed CEA ≥ 5 ng/ ml as risk factor for LN involvement( p=0.0400). Multiple logistic regression analysis showed that solid adenocarcinoma and squamous cell carcinoma recurred more frequently than adenocarcinoma with GGO (p=0.0619, odds ratio 4.969, 95%CI 0.9242~37.67).

Abstract
We report a case of coexistence of sarcoidosis and thymic carcinoid. A 57-year-old man was pointed out the anterior mediastinal tumor when his generator of pacemaker was exchanged. The tumor was diagnosed as atypical carcinoid by percutaneous needle biopsy. Chest computed tomography (CT) revealed the mediastinal and right hilar lymphadenopathy. Preoperative transbronchial aspiration cytology revealed no malignancy and extirpation of the anterior mediastinal tumor was carried out together with left diagraphmatic nerve and pericardium. The histopathological examination of the pretracheal lymph node was sarcoidosis. Postoperative radiation was performed because the thymic carcinoid invaded the pericardium. The right hilar lymph node was enlarged after the radiation. Five months later, follow-up chest CT showed reduction of the right lymph node. He has been alive without recurrence of the thymic carcinoid for 3 years. Simultaneous occurrence of sarcoidosis and thymic carcinoid is extremely rare. Assessment of mediastinal lymph node is difficult either preoperatively and postoperatively. Histological confirmation of the lymph node and careful follow-up are necessary.

Abstract
We herein present five cases of bilateral intractable secondary spontaneous pneumothorax associated with chronic severe lung diseases that were successfully treated with a modified form of a previously reported surgical procedure, the "total pleural covering technique," under video-assisted thoracic surgery. We performed the total pleural covering technique modified with a preceding coverage of air-leak points with polyglycolic acid sheets. In this series, the median length of surgery was 106 min (range: 67-220 min) on the unilateral side (10 sides). No significant surgical complications were observed, but one patient died on day 23 after the operation, due to respiratory insufficiency on the basis of the underlying lung disease. The remaining four patients have been followed up regularly (mean follow-up time: 23 months; range: 1-54 months) and there has been no recurrences of pneumothorax. We believe that the total pleural covering technique is a useful method; however, special attention should be paid to the underlying disease in order to identify patients who would be most likely to benefit from the procedure.

Abstract
The patient was a 68 year-old woman who had a history of treatment of pulmonary tuberculosis 35 years ago. She has experienced dyspnea and hemosputa since several years ago and has been followed up as having chronic empyema. She was admitted to our hospital due to recent exacerbation of symptoms. X-ray films and computed tomography scans of the chest showed the right thoracic cavity to be totally filled with a mass and the shift of mediastinum to the left side. After several days from admission, she needed mechanical ventilation support due to dyspnea exacerbation. Emergency decortication with right pneumonectomy through median sternotomy with anterolateral incision was performed. Postoperative course was uneventful. Pathlogical diagnosis was chronic expanding hematoma.

Abstract
Secondary spontaneous pneumothorax (SSP) such as lymphangioleiomyomatosis (LAM), bronchiolitis obliterans (BO) is intractable or repeated the recurrence of pneumothorax. The most effective chemical pleurodesis for intractable pneumothorax is talc poudrage and so on that is associated with a reduction in the rate of pneumothorax recurrence. However, severe and broad pleural adhesion due to the pleural interventional procedures sometimes cause serious bleeding when the patients undergo lung transplantation. We must be considered for new approaches to these intractable secondary pneumothoraces which replaced traditional conservative and surgical approaches. We had proposed new 2 approaches of total pleural covering (TPC) and awake surgical intervention (ASI) for intractable pneumothorax. We applied the TPC modified with coverage of air leak points with polyglycolic acid (PGA) sheet to 5 patients with intractable bilateral pneumothorax to reduce the risk of excessive bleeding by chemical pleurodesis in lung transplantation. The bilateral pneumothorax was well controlled, and no recurrence has been observed. TPC is reliable procedure for management intractable bilateral SSP. For 12 high-risk patients with other underling pulmonary diseases on general poor conditions, a surgical intervention was performed in awake condition. The air leaks were stopped in 11 cases except for 1 case. The recurrence of pneumothorax after surgery was 2 cases. ASI for intractable secondary pneumothorax can be applicable to selected patients with deteriorated general condition.

Abstract
We report a case of dedifferentiated chondrosarcoma of the chest wall. After resection, the chest wall defect was reconstructed using polypropylene mesh and a transverse rectus abdominis myocutaneous flap. A 61-year-old woman presented with a 16-year history of a slow-growing mass underneath the right chest wall. After percutaneous biopsy, preoperative cytopathological examination of the large mass revealed dedifferentiated chondrosarcoma. The tumor was resected with a wide margin along with the chest wall including skin, the right seventh to tenth ribs, and part of the diaphragm. The chest wall defect was reconstructed with a polypropylene (Marlex) mesh sheet followed by a left-side transverse rectus abdominis myocutaneous flap.

Abstract
We present a case of bilateral intractable pneumothorax associated with a modified form of lymphangioleiomyomatosis (LAM), successfully treated with a previously reported surgical procedure, the total pleural covering (TPC) technique, under video-assisted thoracic surgery. The patient was a 28-year-old woman with bilateral pneumothorax secondary to LAM who had undergone thoracoscopic surgery in another hospital. We performed bilateral TPC modified with a preceding coverage of air leak points with polyglycolic acid sheets for reinforcement. Although a minor air leak after the surgery necessitated a mild pleurodesis on the right side, the bilateral pneumothorax was well controlled, and no recurrence has been observed for 9 months. We believe that TPC is a safe and reliable procedure for the management of intractable pneumothorax secondary to LAM. It also has the potential to reduce risk of excessive bleeding in lung transplantation.

Abstract
BACKGROUND The ability to express genes with potential immunoregulatory capacity could reduce allograft rejection (AR). This study examined the effect of ex vivo lipid-mediated transbronchial human interleukin-10 (hIL-10) gene transfer on AR and the intragraft cytokine profile in a rat model of lung transplantation. METHODS Left single lung transplants were performed between a highly histoincompatible combination of inbred rats. The donor left lung was extracted and intrabronchially instilled with a plasmid encoding hIL-10 (IL-10 group) or Escherichia coli beta-galactosidase (control group), mixed with a cationic lipid. At 3 and 6 days after transplantation, the degree of AR was graded histologically (stage 1-4) and several pathologic categories of inflammation were scored on a scale of 0 to 4 according to the percentage of involvement. Intragraft cytokine profile was examined by real-time reverse transcription polymerase chain reaction. RESULTS The stage of AR (3.1 +/- 0.4 vs 3.8 +/- 0.4) and the pathologic scores for edema (2.3 +/- 0.8 vs 3.2 +/- 0.4), intraalveolar hemorrhage (0.3 +/- 0.5 vs 2.2 +/- 0.8), and necrosis (0.3 +/- 0.5 vs 1.2 +/- 0.4) in the IL-10 group were significantly decreased compared with the control group at Day 6. IL-2 and tumor necrosis factor-alpha messenger RNA expression levels on Day 3 were significantly decreased in the IL-10 group. CONCLUSIONS Ex vivo lipid-mediated transbronchial hIL-10 gene transfer attenuated acute inflammation associated with AR, which was related to decreased levels of proinflammatory cytokine gene expression in a rat model of lung transplantation.

Abstract
The patient was a 32-year-old woman. She suffered repeated hemoptysis due to a congenital right pulmonary artery deficiency and underwent right pneumonectomy at 19 years of age. Immediately after the operation, postpneumonectomy syndrome appeared. The left main bronchus was compressed and almost obstructed, and so metallic stent was urgently installed. However, she subsequently suffered from repeated stenosis due to granulation and repeated obstructive pneumonia. She underwent 7 stent installations, laser therapy, low dose radiotherapy, and ballooning to treat her airway stenosis. However, her left main bronchus gradually became a severe stenosis like a pinhole. When she admitted to our hospital due to obstructive pneumonia last time, it was impossible to install usual airway stents because of extreme kinking of airway and severe stenosis. Therefore, a vascular stent for iliac artery was chosen to treat her airway stenosis and the stent was placed to regain good patency. As a result of the treatment, she had immediate relief of symptoms and survived obstructive pneumonia.

Abstract
The patient was 70-year-old man. He had complained of general fatigue and hoarseness for 5 months. Chest computed tomography scan demonstrated a large anterior mediastinal tumor. The diagnosis of high grade malignant sarcoma was established with needle biopsy and the complete resection through median sternotomy was conducted. The tumor was histopathologically diagnosed pleomorphic liposarcoma. Six months after operation, right supraclavicular lymph node metastasis was noted. Radiotherapy was performed, but the liver metastasis appeared subsequently 16 months after operation. Pleomorphic type is considered one of the poorest prognostic liposarcoma and should be required special attention.

Abstract
Surgical approach is one of the most crucial aspects in the treatment of superior sulcus tumor (SST). Posterior approach as described by Paulson and coworkers is appropriate for the resection of SST invading posterior part of the 1st rib and the vertebrae, whereas anterior approaches as described by Masaoka, Dartevelle, Grunenwald, or Rusca are suitable for resection of SST involving subclavian vessels. We present 2 cases of SST who underwent complete resection through the posterior approach and a modified hemi-clamshell approach, respectively. We also discuss the surgical approaches for SST with referring to literatures.

Abstract
In late years the cancer adjuvant chemotherapy shifts from an inpatient care to an outpatient treatment. For operated lung cancer patients, outpatient chemotherapy center has been working since October 2005 in our hospital. Chemotherapy regimens were carboplatin (CBDCA) + paclitaxel (PTX), CBDCA + gemcitabine (GEM), docetaxel (DTX) + tegaful-gimeracil-oteracil potassium (S-1), and GEM + vinorel bine (VRE). CBDCA was chosen instead of cisplatin (CDDP) and non-platinum doublets are also used because of less toxicity and more time saving. Adjuvant chemotherapy has been performed for a total of 25 outpatients. Twenty-two out of 25 completed chemotherapy. Neutrophilopenia was the most common toxicity and grade 3 or 4 neutrophilopenia was seen in 6 patients. Adjuvant chemotherapy of outpatients can be completed safely by the choice of a safe regimen, supportive therapy for the toxicity, and cooperation with the community medicine organization. Our chemotherapy regimen are thought to be feasible for postoperative lung cancer outpatients.

Abstract
Recently, endoscopic procedures including surgery, intervention, and examination have been widely performed. Medical practitioners are required to record the procedures precisely in order to check the procedures retrospectively and to get the legally reliable record. Medical Forensic System made by KS Olympus Japan offers 2 kinds of movie and patient's data, such as heart rate, blood pressure, and Spo, which are simultaneously recorded. We installed this system into the bronchoscopy room and have experienced its benefit. Under this system, we can get bronchoscopic image, bronchoscopy room view, and patient's data simultaneously. We can check the quality of the bronchoscopic procedures retrospectively, which is useful for bronchoscopy staff training. Medical Forensic System should be installed in any kind of endoscopic procedures.

Abstract
BACKGROUND Photodynamic therapy (PDT) is considered a useful and minimally invasive modality for treating centrally located early lung cancer. To date, there has been limited information on the long-term outcome of patients treated with PDT, especially those who are medically operable. METHODS Beginning in 1994, patients with roentgenographically occult bronchogenic squamous cell carcinoma (ROSCC) who met our criteria underwent PDT at Tohoku University Hospital and were followed up through 2006. Our criteria were as follows: (1) ROSCC without distant metastasis; (2) medically operable by means of lobectomy or further resection; (3) longitudinal tumor length of <or= 10 mm; and (4) superficial bronchoscopic tumor findings. RESULTS A total of 48 patients with ROSCC underwent PDT. The complete response (CR) rate was 94% (45 of 48 of patients). Nine patients (20%) had local recurrence after CR. A total of 11 deaths was observed, with 6 resulting from multiple primary lung cancer and only 1 from the original ROSCC. The 5-year and 10-year overall survival rates for all 48 patients were 81% and 71%, respectively. The Cox proportional hazard model showed that only metachronous multiple primary lung cancer was an independent poor prognostic factor. CONCLUSIONS PDT is thought to be a first-line modality for patients who have ROSCC with a tumor length of <or= 10 mm, even if the tumor is medically operable. Most local recurrence can be cured by active therapy such as surgery, radiotherapy, or PDT. Multiple primary lung cancer subsequent to PDT is an important issue from the viewpoint of survival.

Abstract
OBJECTIVE To examine whether immunocytochemistry can distinguish pulmonary large cell neuroendocrine carcinoma (LCNEC) among non-small cell lung cancers (NSCLCs). STUDY DESIGN Tumor touch imprint cytologic specimens of 109 lung cancers were studied. Immunocytochemistry was done using a total of 8 primary antibodies: chromogranin A, synaptophysin, neural cell adhesion molecule, neuron specific enolase, CK34betaE12, thyroid transcription factor-1, cytokeratin 18 and E-cadherin. RESULTS If 2 or 3 antibodies of chromogranin A, synaptophysin and neural cell adhesion molecule were stained positive and CK34betaE12 was not stained, pulmonary LCNEC can be selected accurately among other NSCLCs with 100% sensitivity and 100% specificity. CONCLUSION This study reveals that immunocytochemistry can help distinguish LCNEC of the lung from other NSCLCs.

Abstract
Food acquisition in animals that construct burrows for foraging is influenced by burrow structure associated with food distribution and searching patterns. The burrowing patterns of the oriental mole cricket ( Gryllotalpa orientalis Brumeister, 1838) (Orthoptera: Gryllotalpidae) were investigated based on analyses of the relation between burrow morphology and plant distribution. To assess differences between horizontal burrows (HB) with and without vertical burrows (VB), the number of branching points, the length of the horizontal parts, the plant ratio of the burrow area, and the burrow fractal dimension were compared. The size of the burrow area was positively related to the degree of branching. Cyperaceae and Gramineae occurred less frequently, whereas Hydrocotyle sibthorpioide Lam. and areas with no plants were more frequent in the burrow area than in the quadrat area. Juncaceae and Persicaria thunbergii (Siebold and Zucc.) H. Gross ex Nakai occurred more frequently and Lindernia crustacea (L.) F. Muell. occurred less frequently in HB without VB than in HB with VB. The ratio of burrow length to the number of branching points was not significantly different between HB with or without VB. HB with VB had a nearly planar structure (higher burrow fractal dimension) than that of HB alone. HB structure and plant composition of the burrow area differed depending on the presence of VB.

Abstract
FBXW7 is reported to be a tumor suppressor gene, and the functional inactivation of FBXW7 has been reported in various human tumors. In this study, we investigated the FBXW7 gene in human thymoma; although no mutations were evident, a significantly high frequency of methylation in the FBXW7 beta-form promoter was observed in types B1 or higher (P=0.014). We propose a novel mechanism for the pathogenesis of thymoma by FBXW7 beta-form and hypothesize that expressional suppression plays an important role in the malignant potential of thymoma.

Abstract
We investigated surgical complications and prognosis of bronchoplasty and bronchoplasty with pulmonary angioplasty (broncho-angioplasty) for lung cancer. Between October 2000 and October 2007, 37 bronchoplastic procedures were done in 572 patients who underwent lung resections for lung cancer. Eleven (29.7%) bronchoplasties were done with pulmonary angioplasty. There was no operative mortality and 1 hospital mortality (2.7%) causing by myocardial infarction. Six of 11 postoperative complications were bronchial complications and 2 additional lung resections were needed. The 5-year survival for all patients was 55.2% and for bronchoplasty was 57.8%. Though the 5-year survival of broncho-angioplasty was not able to calculate at present, the 3-year survival of which was 72.9%. There was no death of patients with adenocarcinoma after introduction of pre-operative assessment by FDG-PET for lymph node metastasis. These data suggest that bronchoplasty and broncho-angioplasty are safe operative procedures and could provide acceptable intermediate survivals with modern multimodality diagnostic and therapeutic tools.

Abstract
Recently, adjuvant chemoradiotherapy showed possible survival advantage in the western prospective studies. A feasibility study was conducted. Adjuvant concurrent chemoradiotherapy with carboplatin (CBDCA) + paclitaxel (PTX) was performed to 4 outpatients with resected locally advanced lung cancer. A total of 60 Gy was given during about 7 weeks, and concurrent CBDCA 2 mg/AUC + PTX 45 mg/m2 was administered weekly. Grade 2 neutropenia was seen in 2 patients, grade 2 esophagitis was seen in 1, and grade 2 peripheral neuritis was in 1. Grade 3 or more toxicity was never seen. One patient had to be hospitalized because of esophagitis, but other 3 patients had completed all course of the therapy as outpatients. Adjuvant concurrent chemoradiotherapy with CBDCA + PTX was thought to be feasible to the resected locally advanced lung cancer patients. Prospective study will be conducted to examine the efficacy of this treatment.

Abstract
The shortage of donor organs has been 1 of the major obstacles to solid organ transplantation. Typical lung donor criteria include clear lung field on chest radiograph, adequate oxygenation, acceptable lung compliance, and satisfactory bronchoscopic findings. To extend usage of available donors, liberalization of donor lung selection criteria has been facilitated, however, marginal donor lungs must be used with discretion, because donor lung injury, especially that related to infection, has a potential leading to early post-operative death of the recipient. From March 2000 to December 2006, we evaluated 15 braindead donors and at least 1 of the lungs from 9 donors was judged suitable for transplantation. One of 9 recipients developed severe pneumonia cased by carbapenems-resistant Pseudomonas aeruginosa possibly originating from the donor lungs, eventually leading to death. The chest radiograph and oxygenation of the donor had been satisfactory, however, a moderate amount of mucopurulent secretions was observed by bronchoscopic inspection and the donor had been given a cefozopran for 9 days before the procurement operation. Remaining 8 recipients were free from air-way infection in the early postoperative period. We discuss the status and problems of donor lung evaluation for transplantation with regard to donor lung infection.

Abstract
Folylpolyglutamate synthase (FPGS) catalyzes the polyglutamation of folic acid, methotrexate, and pemetrexed to produce highly active metabolites. To characterize genetic variation in the FPGS gene, FPGS, have resequenced the gene in four different ethnic populations. Thirty-four single nucleotide polymorphisms were identified including five nonsynonymous coding single nucleotide polymorphisms that altered the FPGS protein sequence: F13L and V22I polymorphisms in the mitochondrial isoform of FPGS, and R466/424C, A489/447V, and S499/457F polymorphisms, which exist in both the mitochondrial and cytosolic isoforms. When expressed in AuxB1 cells, the A447V cytosolic variant was functionally similar to the wild-type cytosolic (WT Cyt) allozyme, whereas the R424C and S457F cytosolic variants were reduced by approximately 2-fold in protein expression compared with WT Cyt (P < 0.01). The intrinsic clearance of glutamate was reduced by 12.3-fold (R424C, P < 0.01) and 6.2-fold (S457F, P < 0.01), whereas the intrinsic clearance of methotrexate was reduced by 4.2-fold (R424C, P < 0.05) and 5.4-fold (S457F, P < 0.05) in these two cytosolic variants when compared with the WT Cyt isoform. Additionally, the in vitro enzyme velocity at saturating pemetrexed concentrations was reduced by 1.6-fold (R424C, P < 0.05) and 2.6-fold (S457F, P < 0.01) compared with WT Cyt. AuxB1 cells harboring these same cytosolic variant allozymes displayed significant increases in the EC(50) for folic acid and in the IC(50) values for both methotrexate and pemetrexed relative to the WT Cyt form of FPGS. These observations suggest that genetic variations in FPGS may alter the efficacy of antifolate therapy in cancer patients.

Abstract
It may be essential for taking appropriate therapeutic decisions in cases with early central-type lung cancer, to know the depth of tumor invasion of the bronchial wall at the laminar level. When a tumor penetrates the cartilaginous layer, photodynamic therapy (PDT) may no longer effective. For optimal therapeutic outcome, the physicians should know accurately whether or not the lesion has invaded the cartilaginous layer. Endobronchial ultrasonography (EBUS) is the sole tool available currently for depicting the laminar structure of the bronchial wall in clinical use. But mastery is required for judging the extent of tumor invasion of the bronchial wall from the ultrasonogram. Even experienced interpreters have to depend on their subjective judgment. We employed image analysis software to digitize the EBUS image. This allowed us to draw a plot of the EBUS data from the bronchial wall and perform statistical analysis for an objective assessment. In this study, we examined the ultrasound images of the bronchial wall structure using 20 MHz and 30 MHz transducers. The results showed that the 30 MHz transducer was significantly more useful for delineating the bronchial wall layers than the 20 MHz probe. Our image analysis is an objective evaluation, and any examiner should arrive at the same results.

Abstract
Blunt bronchial injury is rare but crucial injury. A 17-year-old female was admitted due to traumatic injury. She was diagnosed with bilateral lung contusion, multiple rib fractures, spleen damage and the suspicion about the complete transection of the left main bronchus on X-ray and computed tomography (CT). She was brought to our hospital at 30 hours later from injury. Bronchoscopy revealed the complete transection and the edema of the left main bronchus. She underwent a resection of the disrupted portion and end-to-end anastomosis of left main bronchus without lung resection. We should be an immediate and accurate diagnosis of tracheobronchial disruption by X-ray, CT and bronchoscopy whenever we evaluate patients with blunt chest trauma.
