Surgical Outcomes of Patients With Stage III Thymoma in the Japanese Nationwide Database.

Background: To investigate the clinical characteristics and therapeutic outcomes of patients who underwent surgery for stage III thymoma in Japan.

Methods: Using the Japanese nationwide database, which contains the records of 2,835 patients with thymic epithelial tumors who underwent treatment between 1991 and 2010, we extracted and analyzed the records of those who underwent surgery for stage III thymoma.

Results: A total of 310 patients (170 males, 140 females; median age, 58 years) were analyzed.

Proposal of a new prognostic staging system for pulmonary metastases from colorectal cancer.

Purpose: The aim of this retrospective study was to establish a new prognostic staging system for pulmonary metastases from colorectal carcinoma (CRC).

Methods: The baseline characteristics and outcomes on 352 CRC patients who underwent complete pulmonary resection were collected from 19 institutions by the Japanese Society for Cancer of the Colon and Rectum (JSCCR) Study Group (group A). The clinical and pathological factors were entered into a multivariate analysis to identify independent variables that were helpful for accurately predicting the long-term prognosis after pulmonary resection.

Prognostic factors in patients undergoing complete resection of pulmonary metastases of colorectal cancer: a multi-institutional cumulative follow-up study.

Purpose: The aim of this retrospective study was to establish the prognostic factors for overall survival after pulmonary resection for lung metastases of colorectal carcinoma (CRC).

Methods: The baseline characteristics and outcomes of 266 CRC patients undergoing complete pulmonary resection were collected from 19 institutions by the Japanese Society for Cancer of the Colon and Rectum (JSCCR) Study Group. We used the Cox proportional hazard regression to identify independent prognostic factors for OS.

[Case of loxoprofen sodium-induced eosinophilic pneumonia that occurred ipsilaterally after VATS lobectomy for lung cancer].

A 76-year-old man was admitted because of dry cough and dyspnea two weeks after VATS lobectomy for lung cancer. Chest radiographs and computed tomography showed interstitial shadows in the only operative lung side. Although antibiotic drugs were given because we believed it to be postoperative pneumonia, abnormal shadows on chest radiographs increased.

Accuracy of PET for diagnosis of solid pulmonary lesions with 18F-FDG uptake below the standardized uptake value of 2.5.

Unlabelled: Benign and malignant pulmonary lesions usually are differentiated by 18F-FDG PET with a semiquantitative 18F-FDG standardized uptake value (SUV) of 2.5. However, the frequency of malignancies with an SUV of <2.

Increased thymocyte CD4+CD8+ cells and T-cell receptor beta gene rearrangements in thymoma.

Epithelial cells in thymoma and thymic carcinoma may influence T-cell development in the tumor. In this study, we investigated the cell surface phenotype and T-cell receptor (TCR) gene rearrangement of thymocytes in thymic tumors. TCR rearrangement was observed in all cases of thymoma (A, AB, B1-2).

[A case of Paragonimus miyazakii with migrating infiltrates: use of ELISA in diagnosis and treatment].

A 47-year-old man was referred to our clinic with abnormal chest radiographs. He was free of symptoms, but his chest CT demonstrated transient migrating infiltrates. Peripheral blood revealed eosinophilia and eosinophilic pneumonia was suspected.
