Bioethics 30 ( 1 ) 40 - 49 2020
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Japan Association for Bioethics
In this paper, 437 clinical ethics consultation cases handled at our hospital in the past 6 years were subjected to 4-step coding by referencing the SCAT method, a qualitative research method. We focused on the themes and concepts shared across various cases and defined these as "key terms." The following 9 key terms were extracted: "off-label medical treatment" (207 cases), "use of unapproved drugs" (33 cases), "conflicting treatment strategies" (32 cases), "interacting with patients who have no relatives" (14 cases), "withholding treatment" (11 cases), "mental support for physicians" (10 cases), "withdrawing treatment" (9 cases), "support for family" (7 cases), and "protection of personal information" (6 cases). While the 7 classifications created based on explanations of the Japan Council for Quality Health Care in "Approaches to Evaluation" set external scenarios in which ethical problems are expected to be encountered, the present 9 key terms are thought to present a part of the internal dilemmas faced by medical professionals.

© 2019 Introduction: Large cell neuroendocrine carcinoma (LCNEC) of the thymus is an extremely rare neoplasm. Presentation of case: We report a rare case of LCNEC of the thymus in a 55-year-old woman. Her chest roentgenogram during a routine checkup revealed an abnormal shadow in the mediastinal left upper lung field. Chest computed tomography showed an anterior mediastinal mass measuring 4.8 × 4.0 cm. Positron emission tomography with 18F-fluorodeoxyglucose (FDG) showed high FDG accumulation at the lesion. To obtain a definitive diagnosis and achieve complete resection, a surgery was performed. The postoperative diagnosis was thymic LCNEC; it was classified as a Masaoka stage III tumor due to the invasion of tumor cells into the left lung. Postoperatively, the patient received adjuvant chemotherapy and survived without any signs of recurrence for 30 months after surgery. Discussion/conclusion: The detailed clinical features of thymic LCNEC remain unknown because of its rarity. In total, 20 cases of resection for LCNEC, including the present case, have been reported in the English language literature; we have presented a review of these cases and discussed the optimal therapy for this rare and virulent tumor of the thymus.

© 2018 Edizioni Minerva Medica We herein report a rare case of primary ectopic mediastinal goiter in a 45-year-old woman. a chest roentgenogram at a regular checkup revealed an abnormal shadow in the mediastinal right upper lung field. Chest computed tomography showed a hypervascular mass in the anterior mediastinum with compression of the left brachiocephalic vein, which extended to the right middle mediastinum. an operation was performed to obtain a definitive diagnosis and achieve complete resection. The tumor with tight adhesion to the great vessels was successfully resected by L-shaped mini-sternotomy combined with right-sided video-assisted thoracic surgery (VaTS). The postoperative diagnosis was primary ectopic mediastinal goiter. Right-sided VATS and an L-shaped mini-sternotomy approach allowed tumor resection with sufficient surgical exposure and a good cosmetic outcome. We discuss the surgical approach for resection of this rare anterior mediastinal tumor extending to the middle mediastinum.

Language：Japanese Publishing type：Research paper (scientific journal)
Background: The systemic immune-inflammation index (SII) is reported to be associated with clinical outcomes and has been proven to be a promising prognostic indicator in several solid tumor types. To the best of our knowledge, however, no studies regarding SII in patients with resectable non-small cell lung cancer (NSCLC) are available. Materials and Methods: Three hundred forty-one patients with NSCLC who underwent surgery at our Institution between 2008 and 2012 were included. The SII was calculated using the formula: platelet count × neutrophil/lymphocyte count. The optimal cutoff value was calculated using the Cutoff Finder (http://molpath.charite.de/cutoff). Univariate and multivariate analyses were calculated by the Cox proportional hazards regression model. Results: The optimal cut-off value was 471.2×109/l for SII. A low SII was associated with female gender, never smoking status, adenocarcinoma histology, higher pathological TNM stage and low level of serum C-reactive protein, but not age, serum carcinoembryonic antigen or cytokeratin 19 fragment level. Patients of the low SII group had a significantly better 5-year overall survival than those with high SII (83.61% vs. 60.39%, p<0.001). Multivariate analysis revealed that the SII was a significant independent predictive indicator for cancer-specific survival (p=0.007). Conclusion: This is the first study to demonstrate that the SII could represent an independent prognostic factor for patients with resectable NSCLC.

© 2018 Georg Thieme Verlag KG. Background We examined the usefulness of fluorodeoxyglucose (FDG) positron emission tomography (PET) in predicting the World Health Organization (WHO) histologic type and Masaoka stage of thymic epithelial tumors. Methods A total of 73 patients with thymic epithelial tumors who underwent preoperative FDG-PET were included. Relationships between the maximum standardized uptake value (SUVmax) and WHO histologic type and the Masaoka stage of the tumor were examined. Differences in SUVmax between the various groups were calculated. To avoid the effect of the tumor size on SUVmax, the ratio of SUVmax to tumor size (SUVmax/T) was also examined. Results There was a significant relationship between SUVmax and WHO histologic type. SUVmax of high-risk thymomas (types B2 and B3) was significantly higher than that of low-risk thymomas (types A, AB, and B1). SUVmax of thymic carcinomas was also significantly higher than those of the low-risk and high-risk groups. The relationship between the SUVmax/T and WHO histologic type showed more significant results. SUVmax and SUVmax/T showed higher values in patients with advanced Masaoka stage disease than in those with early-stage disease. Conclusions FDG-PET can provide useful information for differentiating thymic epithelial tumors. The SUVmax/T is more useful than the SUVmax for differentiating between low-risk and high-risk thymomas.
