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)
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)
The Japan Lung Cancer Society, Japanese Association for Chest Surgery, and Japanese Respiratory Society jointly established the Japanese Joint Committee for Lung Cancer Registration. In 2010, analyses of 11,663 cases of lung cancer that underwent surgical resection in 2004 were performed, then the findings were registered and collected for analysis by the(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)
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)
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)
Tracheal chondrosarcomas are rare, with only 14 cases previously documented. We report a case of chondrosarcoma of the trachea and review other published cases. Our patient was a 34-year-old man who began to feel shortness of breath 8 months after initial hemoptysis. Transverse and coronal computed tomography demonstrated a tumor that was obstructing nearly(More)
We report a case of pulmonary benign metastasizing leiomyoma (BML) from the uterus in a 77-year-old woman. The patient presented for investigation of multiple pulmonary nodules on a routine chest roentgenogram. Because a preoperative diagnosis could not be made, the largest tumor, 3.5 cm in diameter, was resected from the right lower lobe, and histological(More)
BACKGROUND Fine-needle aspiration cytologic technique (FNAC), a method to detect malignancy for undetermined pulmonary nodules, may have a high potential to spread malignant cells from the tumor to the pleural cavity. OBJECTIVE The authors assessed malignant cell spread through the needle tract following FNAC for peripheral lung carcinoma. MATERIALS AND(More)
BACKGROUND The Argon Beam Coagulator (ABC) and neodymium:yttrium-aluminum garnet (Nd:YAG) laser are used for lung tissue contraction. Assessing the damage of treated lung tissue is helpful in choosing devices for pulmonary volume reduction by pneumoplastic procedures. METHODS We assessed the damage of in vitro lung lobes resected at operation for(More)
