To address the biological heterogeneity of lung cancer, we studied 199 lung adenocarcinomas by integrating genome-wide data on copy number alterations and gene expression with full annotation for major known somatic mutations in this cancer. This showed non-random patterns of copy number alterations significantly linked to EGFR and KRAS mutation status and(More)
Small-cell lung cancer (SCLC) is a subtype of lung cancer with poor prognosis. To identify accurate predictive biomarkers and effective therapeutic modalities, we focus on a long noncoding RNA, Hox transcript antisense intergenic RNA (HOTAIR), and investigated its expression, cellular functions, and clinical relevance in SCLC. In this study, HOTAIR(More)
BACKGROUND We aimed to clarify that the size of the lung adenocarcinoma evaluated using mediastinal window on computed tomography is an important and useful modality for predicting invasiveness, lymph node metastasis and prognosis in small adenocarcinoma. METHODS We evaluated 176 patients with small lung adenocarcinomas (diameter, 1-3 cm) who underwent(More)
Giant cell tumor of bone is an osteolytic, usually benign, tumor characterized by the infiltration of osteoclast-like giant cells. The receptor activator of nuclear factor kappa-B ligand pathway has been shown to play a key role in the pathogenesis of giant cell tumor. Treatment for refractory, recurrent, or metastatic giant cell tumor remains challenging.(More)
Methylation is closely involved in the development of various carcinomas. However, few datasets are available for small cell lung cancer (SCLC) due to the scarcity of fresh tumor samples. The aim of the present study is to clarify relationships between clinicopathological features and results of the comprehensive genome-wide methylation profile of SCLC. We(More)
INTRODUCTION Parathyroid adenomas are the most common cause of primary hyperparathyroidism. However, cases of parathyroid adenomas greater than 4cm with osteitis fibrosa cystica are extremely rare. Herein, we report a case of resection of a large ectopic mediastinal parathyroid adenoma. CASE PRESENTATIONS A 46-year-old female with chief complaints of bone(More)
BACKGROUND Dermatofibrosarcoma protuberans (DFSP) may recur locally but rarely metastasizes. Fibrosarcomatous transformation in dermatofibrosarcoma protuberans (FS-DFSP) is said to have worse prognosis compared with ordinary DFSP (O-DFSP). Since DFSP rarely metastasizes, there have been few reports summarizing data on distant metastasis cases at single(More)
The anaplastic lymphoma kinase (ALK) fusion oncogene is observed in 3%-5% of non-small cell lung cancer (NSCLC). Crizotinib and ceritinib, a next-generation ALK tyrosine kinase inhibitor (TKI) active against crizotinib-refractory patients, are clinically available for the treatment of ALK-rearranged NSCLC patients, and multiple next-generation ALK-TKIs are(More)
After the approval of pazopanib for the treatment of soft tissue sarcoma (STS), pneumothorax was reported as an unexpected adverse event during pazopanib treatment. The incidence and risk factors of pneumothorax during pazopanib treatment for STSs have not been established yet. We retrospectively reviewed the cases of all of the STS patients treated with(More)
Background. Soft tissue sarcoma with a hemorrhagic component that cannot be easily diagnosed by needle biopsy is defined here as soft tissue sarcoma with telangiectatic changes (STST). Methods. We retrospectively reviewed clinicopathological data of STST from 14 out of 784 patients (prevalence: 1.8%) with soft tissue sarcoma. Results. Tumors were found(More)
