Abstract We evaluated the usefulness of preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) examinations to predict the pathological features in primary breast cancer. In particular, we evaluated the correlation between the maximum standardized uptake values (SUVmax) obtained by 18F-FDG PET/CT and the Ki67 expression in estrogen receptor (ER)-positive invasive ductal carcinoma (IDC). Primary IDC patients operated between March 2009 and July 2013 at Okayama University Hospital were enrolled. We evaluated the correlations between the SUVmax and age, postoperative pT, histological grade, lymph vascular invasion, status of hormone receptor, human epidermal growth factor receptor 2 (HER2), Ki67 expression and node status. The Ki67 expression was classified as high (>14%) versus low (<14%). We enrolled 138 patients with IDC. Their median SUVmax was 3.85 (range:0-52.57). In a univariate analysis, the SUVmax was significantly related to age, pT, histological grade, lymphovascular invasion, hormone receptor status, HER2 status, node status and Ki67. In the 113 patients with ER-positive IDC, there was a significant correlation between Ki67 and SUVmax (p=0.0030). The preoperative 18F-FDG PET/CT results of IDC patients had significant relationships with pathological status parameters. The determination of the preoperative SUVmax might help classify Luminal A and Luminal B patients among luminal-type breast cancer patients.

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 Stent placement is an essential treatment for airway diseases. Although self-expandable metallic stents and silicone stents are commonly applied for the treatment of airway diseases, these stents are unsuitable for the treatment of small airway diseases encountered in pediatric patients and lung transplant recipients with airway complications. Currently, only vascular balloon-expandable metallic stents are available for the treatment of small airway diseases; however, little research has been conducted on the use of these stents in this field. We have launched a prospective feasibility study to clarify the safety and efficacy of balloon-expandable metallic stents for the treatment of airway diseases.

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 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.
