Abstract
Although several studies have evaluated the local control and survival outcomes in patients undergoing stereotactic body radiotherapy (SBRT) for pulmonary oligometastases, little data are available on the management of local relapse. Here, we present 3 patients who underwent lobectomy and mediastinal lymph node dissection as salvage pulmonary metastasectomy for local relapse after SBRT. The postoperative course has been uneventful for all 3 patients, with no evidence of disease at 40, 51, and 6 months from the salvage metastasectomy. Our experience suggests that salvage pulmonary metastasectomy may be associated with local control and long-term survival in carefully selected patients.

Abstract
Background Patients undergoing complete resection of thymoma occasionally develop a recurrence of thymoma; they are also at risk of developing a second malignancy. The objective of our study was to compare the incidence and mortality of a second malignancy versus a recurrence of thymoma during the postoperative follow-up period after complete resection of thymoma. Methods A retrospective chart review was performed on our prospectively maintained database to identify patients undergoing complete resection of thymoma at our institution between 1991 and 2016. The incidence and related mortality of a second malignancy or recurrence of thymoma were recorded. Results One hundred and sixty-four patients were identified. Follow-up ranged from 1 to 239 months (median 54 months). During follow-up, 12 patients had a recurrence of thymoma and 14 developed a second malignancy. The mean risk ratio of recurrence to second malignancy was 0.58 (95% confidence interval: 0.48-0.69) at 5 years, 0.58 (95% confidence interval: 0.49-0.68) at 10 years, and 0.51 (95% confidence interval: 0.43-0.60) at 15 years. The mean risk ratio of recurrence versus second malignancy for related death was 0.59 (95% confidence interval: 0.50-0.70) at 5 years and 0.61 (95% confidence interval: 0.52-0.72) at 10 years. Conclusion It appears that patients undergoing complete resection of thymoma have a higher incidence of a second malignancy and a greater related mortality rate than a recurrence of thymoma. A multiinstitutional database is required to more rigorously evaluate both risks and to confirm our results.

Abstract
PURPOSE We reported previously a phase II study of adjuvant chemotherapy consisting of four cycles of vinorelbine (25 mg/m2) and cisplatin (40 mg/m2), given on days 1 and 8, every 4 weeks, to Japanese patients with completely resected stage II or III non-small cell lung cancer (NSCLC; UMIN 000005055). However, the follow-up was too short for us to evaluate a definitive 5-year overall survival rate and after-effects. METHODS Between December 2006 and January 2011, 60 patients were enrolled in this study. We analyzed relapse-free and overall survival, long-lasting adverse effects, the influence of treatment on recurrent tumors, and the development of a second primary cancer, in relation with the regimen. RESULTS After a median follow-up period of 95.8 months, the 5-year relapse-free and overall survival rates were 51.7 and 76.7%, respectively. Neuralgia developed in one patient and this was the only case of a long-lasting adverse effect. Recurrence developed in 31 patients, 29 of whom received intensive treatment. Although 16 s (or more) primary neoplasms developed among 13 patients, these were common carcinomas in Japan and did not include sarcoma or hematologic malignancies. CONCLUSION Adjuvant vinorelbine and cisplatin chemotherapy showed encouraging relapse-free and overall survival rates, and long-term safety in Japanese patients with resected NSCLC.

Abstract
OBJECTIVES Cytomegalovirus (CMV) infection remains a major cause of morbidity after lung transplantation. Some studies have reported prognostic factors for the postoperative development of CMV infection in cadaveric lung transplantation (CLT), but no research has been performed in living-donor lobar lung transplantation (LDLLT). Therefore, we analysed the possible risk factors of post-transplant CMV infection and the differences between LDLLT and CLT. METHODS The development of CMV disease and viraemia in 110 patients undergoing lung transplantation at Kyoto University Hospital in 2008-2015 were retrospectively assessed. The prognostic factors in the development of CMV infection and the differences between LDLLT and CLT were analysed. RESULTS Among 110 patients, 58 LDLLTs and 52 CLTs were performed. The 3-year freedom rates from CMV disease and viraemia were 92.0% and 58.5%, respectively. There was no difference in the development of CMV infection between LDLLT and CLT (disease: 94.6% vs 91.0%, P = 0.58 and viraemia: 59.3% vs 57.2%, P = 0.76). In preoperative anti-CMV immunoglobulin status, R-D+ recipients (recipient: negative, donor: positive) and R-D- recipients (recipient: negative, donor: negative) tended to have higher and lower cumulative incidences, respectively, of CMV infection (disease: P = 0.34 and viraemia: P = 0.24) than that with R+ recipients (recipient: seropositive). Significantly lower cumulative incidence of CMV viraemia was observed in patients receiving 12-month prophylactic medication (70.6% vs 36.8%, P < 0.001). Twenty-eight patients (25.5%) had early cessation of anti-CMV prophylaxis due to toxicity; however, the extended prophylaxis duration did not increase the incidence of early cessation (P = 0.88). These trends were seen in both LDLLT and CLT. CONCLUSIONS We found that there was no difference in the development of CMV infection between LDLLT and CLT. Twelve-month prophylaxis protocol provides beneficial effect without increased toxicity also in LDLLT.

Abstract
The vinorelbine (VRB) plus cisplatin regimen is widely used to treat non-small cell lung cancer (NSCLC), but its cure rate is poor. Drug resistance is the primary driver of chemotherapeutic failure, and the causes of resistance remain unclear. By focusing on the focal adhesion (FA) pathway, we have highlighted a signaling pathway that promotes VRB resistance in lung cancer cells. First, we established VRB-resistant (VR) lung cancer cells (NCI-H1299 and A549) and examined its transcriptional changes, protein expressions, and activations. We treated VR cells by Src Family Kinase (SFK) inhibitors or gene silencing and examined cell viabilities. ATP-binding Cassette Sub-family B Member 1 (ABCB1) was highly expressed in VR cells. A pathway analysis and western blot analysis revealed the high expression of integrins β1 and β3 and the activation of FA pathway components, including Src family kinase (SFK) and AKT, in VR cells. SFK involvement in VRB resistance was confirmed by the recovery of VRB sensitivity in FYN knockdown A549 VR cells. Saracatinib, a dual inhibitor of SFK and ABCB1, had a synergistic effect with VRB in VR cells. In conclusion, ABCB1 is the primary cause of VRB resistance. Additionally, the FA pathway, particularly integrin, and SFK, are promising targets for VRB-resistant lung cancer. Further studies are needed to identify clinically applicable target drugs and biomarkers that will improve disease prognoses and predict therapeutic efficacies.

Abstract
BACKGROUND Whether compensatory lung growth occurs in adult humans is controversial. The aim of this study was to confirm compensatory lung growth by analyzing ipsilateral residual lung after lower lobectomy in living lung transplant donors with quantitative and qualitative computed tomography assessments. METHODS Chest computed tomography and pulmonary function tests were performed in 31 eligible donors before and 1 year after donor lobectomy. Ipsilateral residual lung volume was measured with three-dimensional computed tomography volumetry. The computed tomography-estimated volumes of low, middle, and high attenuations in the lung were calculated. Assessment of the D value, a coefficient of the cumulative size distribution of low-density area clusters, was performed to evaluate the structural quality of the residual lung. RESULTS Postoperative pulmonary function test values were significantly larger than preoperative estimated values. Although postoperative total volume, low attenuation volume, middle attenuation volume, and high attenuation volume of the ipsilateral residual lung were significantly larger than the preoperative volumes, with 50.2%, 50.0%, 41.5%, and 43.1% increase in the median values, respectively (all p < 0.0001), the differences in D values before and after donor lobectomy were not significant (p = 0.848). The total volume of ipsilateral residual lung was increased by more than 600 mL (50%). CONCLUSIONS The volume of ipsilateral residual lung increased, but its structural quality did not change before and after donor lobectomy. The existence of compensatory lung growth in adult humans was suggested by quantitative and qualitative computed tomography assessments.

Abstract
OBJECTIVES Extended thymectomy is a treatment option for myasthenia gravis (MG), but the surgical indications are controversial. Pathologic features of the thymus can be used to predict surgical outcomes, but there is no reliable method for evaluating these characteristics preoperatively. The purpose of this study was to determine whether anterior mediastinal tissue volume, as measured via 3-dimensional computed tomography (3DCT) volumetry, correlates with serum anti-acetylcholine receptor antibody (AChRAb) levels in patients undergoing thymectomy for myasthenia gravis. Therefore, we investigated the relationships among anterior mediastinal tissue volume determined by 3DCT volumetry and AChRAb levels. METHODS The subjects were 28 patients who underwent extended thymectomy and were enrolled retrospectively. We measured volume of the anterior mediastinum and calculated the volumes of more than -30 Hounsfield units (V-30) by using 3DCT volumetry and compared them with perioperative AChRAb levels. The significance of their volumes in MG was examined by comparison with 53 patients without MG. RESULTS V-30 values were related to age and were significantly greater in patients with MG than in patients without MG (P < .001). V-30 values were correlated positively with preoperative AChRAb levels (ρ = 0.505, P = .006) and inversely with the post/preoperative AChRAb ratio (ρ = -0.453, P = .018). The histologic nonadipose tissue ratio was correlated with the V-30/volume of the anterior mediastinum (ρ = 0.700, P < .001). CONCLUSIONS This method for evaluation of the anterior mediastinal tissue volume and AChRAb production may be helpful in establishing a treatment plan for MG.

Abstract
Limited data is available on salvage surgery for local relapse (LR) after stereotactic body radiotherapy (SBRT) for non-small cell lung cancer (NSCLC). We aimed to characterize treatment options and clarify long-term outcomes of isolated LR after SBRT for patients with clinical stage I NSCLC. Herein, we discuss technical aspects, perioperative management, and postoperative follow-up of two patients of the 12 patients undergoing salvage surgery for LR after SBRT at Kyoto University between 1999 and 2013. A 76-year-old male, 15 months after SBRT, underwent a salvage right upper lobectomy combined with adjacent right lower lobe wedge resection via video-assisted thoracoscopic surgery (VATS) for a 5.0-cm mass. Local recurrence was found 5 years after salvage surgery and treated with repeat SBRT, however he died from multiple distant metastases. An 85-year-old male, 14 months after SBRT, underwent a salvage left upper lobectomy via VATS for a 3.5-cm mass. Moderate intrapleural adhesion was noted and required careful dissection on the mediastinum. He is alive with no recurrence at 2 years from salvage surgery. Salvage VATS lobectomy was feasible after SBRT in two patients. Long-term follow-up and continued discussions at multidisciplinary conferences are required.

Abstract
Purpose: To reconcile the heterogeneity of thymic epithelial tumors (TET) and gain deeper understanding of the molecular determinants of TETs, we set out to establish a clinically relevant molecular classification system for these tumors.Experimental Design: Molecular subgrouping of TETs was performed in 120 patients from The Cancer Genome Atlas using a multidimensional approach incorporating analyses of DNA mutations, mRNA expression, and somatic copy number alterations (SCNA), and validated in two independent cohorts.Results: Four distinct molecular subtypes of TETs were identified. The most commonly identified gene mutation was a missense mutation in General Transcription Factor II-I (GTF2I group), which was present in 38% of patients. The next group was identified by unsupervised mRNA clustering of GTF2I wild-type tumors and represented TETs enriched in expression of genes associated with T-cell signaling (TS group; 33%). The remaining two groups were distinguished by their degree of chromosomal stability (CS group; 8%) or instability (CIN group; 21%) based upon SCNA analyses. Disease-free survival and overall survival were favorable in the GTF2I group and unfavorable in the CIN group. These molecular subgroups were associated with TET histology and clinical features including disease-free survival. Finally, we demonstrate high expression of PD1 mRNA and correlation of PD1 and CD8A in the TS subgroup.Conclusions: Molecular subtyping of TETs is associated with disease-free and overall survival. Classification of TETs by a molecular framework could aid in the refinement of staging and in the discovery and development of rational treatment options for patients with TETs.

Abstract
A 55-year-old man with end-stage emphysema underwent a right single-lung transplantation through a posterolateral thoracotomy. The fifth rib was divided and fused back using a biodegradable pin made of polylactide acid and hydroxyapatite. Two weeks postoperatively, he suffered from central vein catheter-related sepsis due to methicillin-sensitive Staphylococcus aureus. After being successfully treated for sepsis, he was discharged. However, 3 months later, computed tomography revealed multiple loculated abscesses in the chest wall and the right pleural space. Reoperative thoracotomy revealed abscesses mainly located around the fifth rib, where the pin was inserted. Both cultures of the abscess and the fifth rib were positive for methicillin-sensitive S. aureus, which suggested that the rib pin was the cause of the secondary infection. This case suggests the rib pins, even if they are biodegradable, could have a risk of infections side effect especially for the immunosuppressed patients.

Abstract
A majority of observational studies on overall survival following thoracoscopic vs open lobectomy for early-stage non-small cell lung cancer did not demonstrate a significant difference, whereas several meta-analyses on this topic showed a significant difference. The PubMed, Scopus, and Web of Science databases were queried for studies published in the English language. We searched for meta-analyses and original studies comparing overall survival between thoracoscopic and open lobectomy for early-stage non-small cell lung cancer. Our meta-analysis, using random effect models and with a hazard ratio as a measure of effect, was performed on original studies. Publication bias was evaluated with funnel plots of precision and the Egger test. Seven meta-analyses on this topic were found and all of them have shown that thoracoscopic lobectomy is associated with significantly more favorable overall survival than open lobectomy, using odds ratio, risk ratio, or risk difference as measures of effect. Our meta-analysis of 11 observational studies demonstrated no significant difference in overall survival between thoracoscopic (n = 2386) and open lobectomy (n = 3494) for early-stage non-small cell lung cancer (pooled hazard ratio: 0.91, 95% confidence interval: 0.76-1.09, P = 0.30). Neither funnel plots of precision nor the Egger test suggested a publication bias. Our meta-analysis, using a hazard ratio as a measure of effect for a time-to-event outcome, did not demonstrate a significant difference in overall survival between thoracoscopic and open lobectomy with the current dataset available in the literature, as opposed to previous meta-analyses.

Abstract
Patients after lung transplantation are at risk for postoperative malignancy mainly due to postoperative immunosuppression. Skin cancer and post-transplant lymphoproliferative disorder (PTLD) are common in Western countries. We retrospectively reviewed the medical records of 120 patients undergoing lung transplantation between April 2002 and July 2015 at Kyoto University. Postoperative malignancy developed in 14 patients(11.7%):PTLD in 8, gastric cancer in 2, breast cancer in 1, glioblastoma in 1, lung cancer in 1, and adenocarcinoma of unknown primary in 1. Seven patients(11.3%)and 7 patients (12.1%)were after living-donor lung transplantation( LDLLT) and cadaveric lung transplantation (CLT), respectively (p=1.00). The overall 5-year survival of patients with postoperative malignancy was 39.3%, which tended to be worse (p=0.059), compared to those without postoperative malignancy(71.4%). All postoperative malignancies were de novo malignancies without any recurrence of original malignancies. Postoperative malignancies occurred after LDLLT as well as after CLT, and seemed to have a negative impact on long-term outcome of lung transplant recipients. The majority was PTLD;however, skin cancer was not recognized, suggesting ethnic differences. We should be careful about postoperative malignancies in follow-up of the lung transplant recipients.

Abstract
BACKGROUND There is a paucity of data regarding adjuvant chemotherapy for resected early stage thymoma. This systematic review was designed to investigate the effect of adjuvant chemotherapy on outcomes in patients with early stage thymomas. METHODS PubMed database was queried for studies containing information on adjuvant chemotherapy following surgery in patients with Masaoka stage I or II thymoma. RESULTS Eight retrospective observational studies were reviewed. The number of patients with stage I or II thymoma was not clearly reported in several studies. Five studies reported on 890 patients with stage I or II patients, including 140 patients (15.7%) who received adjuvant chemotherapy with or without radiotherapy. No study reported short-term mortality in patients undergoing adjuvant chemotherapy following thymectomy. CONCLUSIONS Adjuvant chemotherapy following resection of early thymomas appears to be a safe approach with favorable short-term outcomes. However, long-term outcomes remain unclear. There is no strong evidence to support adjuvant chemotherapy following resection of early-stage thymoma.

Abstract
PURPOSE To determine the relationship between the fractional interstitial volume (Fis), as calculated at dynamic contrast material-enhanced (DCE) computed tomography (CT), and tumor-associated stroma and to analyze its spatial relationship with tumor hypoxia in several xenograft tumor models. MATERIALS AND METHODS All animal experiments were approved by the animal research committee. Mice with three different xenograft tumors (U251, CFPAC-1, and BxPC-3; n = 6, n = 8, and n = 6, respectively) underwent DCE CT then hypoxia imaging with fluorine 18 ((18)F) fluoromisonidazole (FMISO) positron emission tomography (PET) within 24 hours. Immunohistochemical analysis was performed in harvested tumors to detect hypoxia markers and to quantify microvascular and stromal density. Two DCE CT parameters (amount of interstitial space associated with the amount of stroma [Fis] and flow velocity [Fv]) were identified and quantitatively validated by using immunohistochemistry. FMISO uptake within the tumor was also assessed in relation to DCE CT parameters. Imaging and immunohistochemical parameters were assessed by using the Kruskal-Wallis test, Wilcoxon rank-sum test with Bonferroni correction, and Pearson correlation coefficient. RESULTS Almost no α-smooth muscle actin-positive cells were found in the U251 xenograft, while abundant stroma was found in the entire BxPC-3 xenograft and in the periphery of the CFPAC-1 xenograft. Quantitative analysis showed a significant correlation (R = 0.83, P < .0001) between Fis and stromal density. FMISO uptake had a negative correlation with Fis (R = -0.58, P < .0001) and Fv (R = -0.53, P < .0001). CONCLUSION DCE CT can be used to quantify parameters associated with tumor-associated stroma. Tumor hypoxia was Complementarily localized in tumor-associated stroma in these models.

Abstract
This meta-analysis was designed to determine the effect of surgical treatment on overall survival of patients treated surgically for a second non-small cell lung cancer (NSCLC) that occurred after resection of an initial NSCLC. PubMed and Scopus databases were queried. Nine studies were identified. Meta-analyses revealed pooled operative mortality of 7% for the second resection, pooled 5-year overall survival of 46% after resection of the second NSCLC, and 79% after resection of the first NSCLC. These results suggest that surgical resection can be considered for patients who have a second primary NSCLC after resection of an initial lung cancer.

Abstract
OBJECTIVES The optimal material for anterior chest wall reconstruction following chest wall resection remains controversial. The aim of this experimental study was to evaluate short-term, morphological and histological outcomes of anterior chest wall reconstruction with a rigid and bioabsorbable material in a canine model. METHODS Twenty adult beagle dogs underwent anterior chest wall resection. In the experimental group (n = 10), the anterior chest wall was reconstructed with a rigid and bioabsorbable material composed of poly-L-lactide acid matrix (60 wt%) and uncalcined and unsintered hydroxyapatite particles (40 wt%), whereas in the control group it was (n = 10) reconstructed with dual polypropylene mesh sheets. Short-term complication rates were compared with a χ(2) test. Postoperative sternal deviations were evaluated with sternal alignment angles using computed tomography and multiplanar reconstruction and were compared with Mann-Whitney U-test immediately after reconstruction, and at 1, 3, 6, 9 and 12 months postoperatively. Histological findings of the regenerated chest wall tissue were obtained after staining with haematoxylin and eosin and Elastica van Gieson (EVG) and compared at 3, 6, 9 and 12 months. RESULTS There was not a significant difference in the short-term postoperative complication rate (P = 0.53) and the complication rate was 20% (wound infection, n = 1 and lethal mediastinitis, n = 1) in the control group and 10% (wound infection, n = 1) in the experimental group. The postoperative sternal deviation was significantly less remarkable at 1 month (123.3 ± 32.2° vs 159.4 ± 19.7°, P = 0.027), 3 months (109.8 ± 34.7° vs 150.9 ± 34.2°, P = 0.039) and 12 months (61 ± 15.6° vs 170.3 ± 6.6°, P = 0.046) in the experimental group than in the control group, whereas no significant difference was noted immediately after reconstruction (165.7 ± 6.4° vs 168.4 ± 9.1°, P = 0.50). Histological findings showed dense connective tissue in the regenerated chest wall in both groups and showed chondroblasts in the regenerated chest wall tissue at 3 and 6 months only in the experimental group. CONCLUSIONS Our results suggest that anterior chest wall reconstruction with a rigid and bioabsorbable material is feasible and may be a valuable alternative to reconstruction with a non-rigid and non-absorbable material.

Abstract
BACKGROUND The aim of this study was to perform a survival comparison between stereotactic body radiotherapy (SBRT) and sublobar resection (SLR) in patients with stage I non-small-cell lung cancer (NSCLC) at high risk for lobectomy. METHODS All patients who underwent SBRT or SLR because of medical comorbidities for clinical stage I NSCLC were reviewed retrospectively. Propensity score matching (PSM) was performed to reduce selection bias between SLR and SBRT patients based on age, gender, performance status, tumour diameter, forced expiratory volume in 1 second (FEV1) and Charlson comorbidity index (CCI). RESULTS One hundred and fifteen patients who underwent SBRT and 65 SLR were enrolled. The median potential follow-up periods for SBRT and SLR were 6.7 and 5.3 years, respectively. No treatment-related deaths were observed. Before PSM, the 5-year overall survival (OS) was 40.3% and 60.5% for SBRT and SLR, respectively (P=0.008). PSM identified 53 patients from each treatment group with similar characteristics: a median age of 76 years, a performance status of 0-1, a median tumour diameter of ∼20 mm, a median FEV1 of ∼1.8L and a median CCI of 1. The difference in OS became insignificant between the matched pairs (40.4% and 55.6% at 5 years with SBRT and SLR; P=0.124). The cumulative incidence of cause-specific death was comparable between groups (35.3% and 30.3% at 5 years, P=0.427). CONCLUSION SBRT can be an alternative treatment option to SLR for patients who cannot tolerate lobectomy because of medical comorbidities.
