BACKGROUND The Japan Lung Cancer Society, the Japanese Association for Chest Surgery, and the Japanese Respiratory Society jointly established the Japanese Joint Committee for Lung Cancer Registration, which has regularly conducted lung cancer registries for surgical cases in 5-year periods. We analyzed data obtained in these registries to reveal the most(More)
BACKGROUND Although video-assisted thoracic surgery (VATS) has been in use for more than a decade, its application to major lung resection for lung cancer is still not widely practiced. The success of a cancer operation is judged by the long-term survival of the treated patients. Therefore, the goal of the present study was to evaluate long-term outcomes(More)
PURPOSE To investigate prognoses of lung cancer patients prospectively enrolled in the Japan Lung Cancer Registry Study. METHODS Patients newly diagnosed as having lung cancer exclusively in 2002 were enrolled. Follow-up surveys were performed twice, in 2004 and 2009, and the final follow-up data with prognoses were analyzed for 14,695 patients (79%).(More)
OBJECTIVE Sleeve lobectomy is a lung-saving procedure for central tumors for which the alternative is pneumonectomy. The purpose of this study was to report the clinical characteristics, operative results, survival, and late outcomes over 20 years in patients who underwent sleeve lobectomy and pneumonectomy at our institution. METHODS There were 62(More)
INTRODUCTION Women with non-small cell lung cancer (NSCLC) are more likely to have better survival than men. This study intended to assess gender differences in the survival of these patients in a large registry population. METHODS In 2005, the Japanese Joint Committee for Lung Cancer Registration performed a nationwide retrospective registry study(More)
We present two cases of desmoplastic malignant mesothelioma (DMM) with pathological, immunohistochemical, and ultrastructural features. Each patient showed rapid progress and died within 1 year from appearance of the initial symptoms. Macroscopically, both showed a thickened pleura replaced by a tumor that encased the lung. Microscopic results of each(More)
OBJECTIVES Non-small cell lung cancer with mediastinal lymph node involvement is a heterogeneous entity different from single mediastinal lymph node metastasis to multiple nodes or extranodal disease. The objective of this study was to identify the subpopulation of patients with N2 disease who can benefit from surgical intervention. METHODS We reviewed(More)
OBJECTIVE We performed this study to determine the role and prognostic factors of neoadjuvant therapy followed by surgery for locally advanced non-small cell cancer. METHODS One hundred patients with clinical stage III non-small cell lung cancer (79 IIIA, 21 IIIB; 78 males, 22 females; average age 60.5 years) received neoadjuvant therapy, of whom 84(More)
In this study, the prognostic value of determining the nuclear DNA content of thymomas by flow cytometry was evaluated. Of a total 31 resected thymomas, 10 (32%) showed DNA aneuploidy, the presence of which was significantly correlated with an advanced clinical stage of disease. The patients with an aneuploid tumor had a poorer prognosis than those with a(More)
BACKGROUND The chances of pulmonary resection for small-sized lung cancer have increased because of the development of thin-slice computed tomography (CT). Though sublobar resection could be indicated for ground glass opacity (GGO)-dominant adenocarcinoma with low-grade behaviour, the malignant potential of solid-type, small-sized lung cancer has not been(More)
