The overexpression of heterogeneous nuclear ribonucleoprotein (hnRNP) A2/B1 is recently reported informative as a marker of lung cancer for early detection. To examine whether the expression of the proteins is specific for lung cancer, immunological analyses were performed both in lung and non-lung cancer cell lines. In immunostaining and Western blotting,(More)
Metastatic involvement of the peritoneum is not a very rare autopsy finding. Clinically, however, peritonitis carcinomatosis from a lung cancer is infrequently encountered and the pattern of the metastasis has not been studied. A total of 1041 patients with lung cancer who were admitted to our division over a 26-year period were retrospectively analyzed.(More)
BACKGROUND Metastatic involvement of the pancrease is not an uncommon autopsy finding, however, pancreatic metastasis is an infrequent clinical condition and the pattern of the metastases have not been studied. We conducted a retrospective study in order to evaluate the pattern of the metastasis from lung cancer. PATIENTS From 1976 to 1997, 26 patients(More)
A 17-year-old man with high levels of serum AFP and hCG was diagnosed as having primary mediastinal GCT. Cisplatin-based chemotherapy decreased the biomarkers, but the mass showed further growth. Pathological examination of the resected mass revealed a mixture of immature and mature teratomas. Six months after the surgery, the patient died of a(More)
The authors describe a case of lung cancer in a 55-year-old man who complained of back pain. Initial isotopic bone scanning showed no abnormality, however, magnetic resonance (MRI) imaging revealed bone metastasis in thoracic vertebral bone. Even when there is no typical findings of metastasis in bone scintigraphy, MRI imaging would be useful if vertebral(More)
The combined effects of TNP-470, a promising antiangiogenic agent, and SN-38, a camptothecin derivative, were evaluated in four human cultured cell lines derived from non-small cell lung cancer (NSCLC). Cytotoxicity experiments were determined by using a tetrazolium salt (MTT) assay. The inhibitory effects of TNP-470 on cell proliferation were dose related(More)
BACKGROUND Sialyl Lewis X-i antigen has been used as a diagnostic tool for lung adenocarcinoma. However, serum levels of the antigen are also raised in some patients with idiopathic pulmonary fibrosis (IPF) without coexistent malignancy. Expression of the antigen in serum samples of patients with lung adenocarcinoma was evaluated and compared with that of(More)
UNLABELLED In non-small cell lung cancer (NSCLC), pleural effusion is a frequently observed complication, and often provides a treatment difficulties. The aim of this study is to evaluate prognostic significance of pleural effusion in patients with NSCLC. MATERIALS AND METHODS Seven hundred and eight untreated patients with NSCLC who were consecutively(More)
Mass-screening for lung cancer is rather a unique system in Japan. This study illustrates time from finding abnormality on mass-screening to final diagnosis of lung cancer. Among the 517 patients with lung cancer who were admitted to our hospital over a 10-year period up to December 2001, 83 (16.1%) were detected by mass-screening. We reviewed medical(More)
