Abstract A study to evaluate the effect of metformin on the immune system was commenced in July 2014. Metformin is one of the most commonly prescribed drugs for type 2 diabetes, and previous studies have reported that metformin has an anti-tumor effect. The aim of this study is to evaluate the efficacy of metformin on the immune system in human cancer patients in vivo. The primary outcome parameter will be the rate change in the population of CD8+ T cells, which produce multiple cytokines.

Abstract In 2016, Gunma University Hospital’s Medical Accident Investigation Committee released a report reiterating the necessity of medical education and the need for surgeons to master non-technical skills. We designed a 17-h training course for surgical instructors, designed to teach participants how to sufficiently educate surgeon trainees and encourage their professional identity formation. A post-training survey showed that participants improved their awareness, and their behavioral changes led to favorable team performances. We then began offering a 3-h workshop focusing on the participants’ experiences. We propose that the training course using participant narratives is required and effective to establish surgeons’ self-reflection and professional identity as surgeons.

Abstract We retrospectively assessed the dual-time-point (DTP) F-18 FDG PET/CT findings of thymic epithelial neoplasms (TENs) and investigated the diagnostic capacity of PET/CT compared to that of CT for predicting carcinoma. We calculated the ratio of the standardized uptake value of the tumor and that of the aortic arch (T/M ratio) for both the 90-min early scan and the 2-h delayed scan in 56 TEN patients. We used a multivariate logistic regression (MLR) analysis to estimate the CT features of carcinoma. We compared the diagnostic capacities of PET/CT and chest CT using receiver operating characteristic (ROC) analyses. The ROC curve revealed that the appropriate cut-off T/M ratio value for the highest accuracy was 2.39 with 75.0% accuracy. The area under the curve (AUC) was 0.855. The statistical analyses for DTP scans of 35 TEN patients demonstrated 74.3% accuracy and 0.838 AUC for the early scan versus 82.9% and 0.825 for the delayed scan. The MLR analysis indicated that mediastinal fat infiltration was a predictor of carcinoma. The ROC curve obtained for the model yielded an AUC of 0.853. Delayed scanning could improve the diagnostic capacity for carcinoma. The T/M ratio and mediastinal fat infiltration are predictive of carcinoma with moderate diagnostic accuracy.

Abstract  Primary sternal chondrosarcoma is a rare malignant tumor that is refractory to chemotherapy and radiation. Effective therapy is radical resection of the tumor. We present two patients with primary sternal chondrosarcoma who underwent a radical resection of the lower half of the sternum and bilateral ribs, followed by reconstruction with 2 sheets of polypropylene mesh layered orthogonally. The patients have maintained almost the same pulmonary function as preoperative values, with stability of the chest wall. Although there are various ways to reconstruct the anterior chest wall, reconstruction with polypropylene mesh layered orthogonally is an easy-to-use and sufficient method.

Abstract We present the case of a 65-year-old Japanese man diagnosed with chronic empyema (without a bronchopleural fistula) that occurred 7 months after he underwent an extrapleural pneumonectomy for right malignant pleural mesothelioma (MPM). Following thoracic drainage and irrigation for 1 month, we performed surgery by a thoracoscopic approach, in light of his general condition. We performed debridement and removal of the Gore-Tex polytetrafluoroethylene (PTFE) patch that had been used for the reconstruction of the diaphragm and the pericardium. The empyema had not relapsed when he died from recurrence of the MPM at 4 months after the thoracoscopic surgery. This patientʼs case suggests that thoracoscopic debridement and patch removal can be a therapeutic option for not only early-stage (exudative or fibrinopurulent) empyema but also late-stage (organized and chronic) empyema without a bronchopleural fistula, particularly for patients in poor general condition.

Abstract The aim of this study was to explore enhancement patterns of different types of primary lung cancers on 2-phase dynamic computed tomography (CT). This study included 217 primary lung cancer patients (141 adenocarcinomas [ADs], 48 squamous cell carcinomas [SCCs], 20 small cell lung carcinomas [SCLCs], and 8 others) who were examined using a 2-phase dynamic scan. Regions of interest were identified and mean enhancement values were calculated. After excluding the 20 SCLCs because these lesions had different clinical stages from the other cancer types, the mean attenuation values and subtractions between phases were compared between types of non-small cell lung carcinomas (NSCLCs) using the Kruskal–Wallis test. Late phase attenuation and attenuation of the late minus unenhanced phase (LMU) of SCCs were significantly higher than those of ADs (p<0.05). To differentiate SCC and AD in the late phase, a threshold of 80.21 Hounsfield units (HU) gave 52.9% accuracy. In LMU, a threshold of 52.16 HU gave 59.3% accuracy. Dynamic lung CT has the potential to aid in differentiating among NSCLC types.

Abstract We encountered a rare case of thymic cyst accompanied by mediastinitis. A 39-year-old Japanese male presented with fever and chest pain. The chest CT revealed a mass composed of a lobular cystic lesion with inflammation, suggesting the onset of mediastinitis. A definitive histological diagnosis was not obtained, and we performed a thymectomy. Pathologically, the thymic cyst was accompanied by multiple cavities, mimicking thymic cysts, caused by the inflammatory abscess. The surrounding adipose tissue showed inflammatory cell infiltrations with chronic fibrosis. These findings indicate that clinicians should be aware that thymic cysts may cause severe mediastinitis.

Abstract The aim of this study was to investigate whether volumetric positron emission tomography (PET) parameters are prognostic predictors in stage III non-small cell lung cancer patients receiving definitive concurrent chemo-radiotherapy (CCRT) with cisplatin/docetaxel. Cases involving definitive CCRT were reviewed retrospectively, and the maximum standardized uptake value, metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were calculated. The relationships between these PET parameters and prognosis were analyzed. MTV and TLG were significant predictors of distant metastasis-free survival (DMFS) (p = 0.0003 and 0.0005, respectively) and progression-free survival (PFS) (p = 0.001 and 0.0007, respectively). The three-year DMFS rates in patients with low and high MTV were 13.3% and 64.6%, respectively, and the corresponding values in those with low and high TLG were 13.3% and 65.2%, respectively. The three-year PFS rates in patients with low and high MTV were 13.3% and 57.8%, respectively, and the corresponding values in patients with low and high TLG were 13.3% and 57.8%, respectively. However, MTV and TLG were not predictors of local control or overall sur-vival. We demonstrated that volumetric PET parameters were predictors of patients receiving definitive CCRT. Our findings contradict the findings of previous reports and warrant further research to validate them.

Abstract Bronchopleural fistula (BPF) is a severe complication following lung resection. We present the case of a patient with a history of advanced lung cancer, who had undergone induction chemoradiotherapy followed by right middle and lower lobectomy, and who developed BPF after completion right pneumonectomy. Although we had covered the bronchial stump with an omental pedicled flap, BPF was found on postoperative day 19. We covered the fistula with n-butyl-2-cyanoacrylate (NBCA) using bronchoscopy. Although we had to repeat the NBCA treatment, we ultimately cured the patient’s BPF and no recurrence was observed up to 15.2 months after surgery.

Abstract Although chronic kidney disease (CKD) commonly develops after lung transplantation (LT), living-donor kid-ney transplantation (LDKT) for CKD after LT is known to provide favorable outcomes. We describe the long-term follow-up findings of a patient who underwent LDKT after bilateral cadaveric LT. A 37-year-old male underwent LDKT for CKD 18 years after receiving bilateral cadaveric LT. He developed chronic lung allograft dysfunction (CLAD) 20 years after the LT; however, at 26 years after the initial LT, he is still alive with no pro-gression of CLAD or CKD. KT could be a viable option for CKD even after LT in Japan.
