RATIONALE Birt-Hogg-Dubé (BHD) syndrome, a rare inherited autosomal genodermatosis first recognised in 1977, is characterised by fibrofolliculomas of the skin, an increased risk of renal tumours and multiple lung cysts with spontaneous pneumothorax. The BHD gene, a tumour suppressor gene located at chromosome 17p11.2, has recently been shown to be(More)
CD44s is a principle hyaluronate (HA) receptor and has been reported to play an important role in cancer cell invasion and metastasis. The aim of our study is to determine if the interaction between HA and CD44s influences in vitro chemosensitivity of non-small cell lung cancer (NSCLC). NSCLC cell line, H322 cells, transfected with the CD44s gene(More)
Various autoimmune diseases have been reported to occur in patients with sarcoidosis. However, coexistence of sarcoidosis and antiphospholipid syndrome (APS) is extremely rare. We describe a 59-year-old female patient with pulmonary sarcoidosis who had preceding APS. Her previous medical history consisted of a miscarriage and ischemic colitis. She was(More)
BACKGROUND Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been successfully used to treat patients with non-small cell lung cancer (NSCLC) harboring EGFR mutations. However, despite an initial excellent response, recurrence within one or two years is common. Diagnosis and treatment of leptomeningeal metastasis (LM), a form of(More)
Osteopontin (OPN) is a multifunctional cytokine involved in cell signaling by interacting with alphavbeta3 integrins. Recent clinical studies have indicated that OPN expression is associated with tumor progression and poor prognosis among patients with lung cancer. However, the biological role of OPN in human lung cancer has not yet been well-defined. The(More)
We report a case of thymic carcinoma associated with dermatomyositis (DM) in a 53-year-old man. The patient presented with the characteristic features of a skin rash with Gottron’s papules, proximal muscle weakness, and increased serum levels of the muscle-associated enzymes. Comprehensive clinical examinations revealed an anterior mediastinal tumor. We(More)
BACKGROUND Recently, driver oncogenes in adenocarcinoma of the lung were identified, and several molecular target agents were introduced in the clinical setting. However, there are few reports on the frequency of gene abnormalities in young patients with lung cancer. MATERIALS AND METHODS Twelve patients with lung adenocarcinoma aged 40 or younger at(More)
This report describes a case of isolated congenital spleen agenesis complicated by chronic thromboembolic pulmonary hypertension (CTPH) in a 44-year-old female patient. The patient had increasing exertional dyspnoea and thrombocytosis. An echocardiogram showed severe pulmonary hypertension and right ventricular hypertrophy, and contrast-enhanced chest CT(More)
Endostatin (ED) is a carboxyl-terminal fragment of collagen XVIII with strong antiangiogenic activity. ED has been considered as a highly specific inhibitor of endothelial cell proliferation and migration through interaction with its receptor on the surface of endothelial cells. Recently, direct antitumor effects of ED in colon cancer cells and head and(More)
