BACKGROUND This study was conducted to evaluate the prognostic significance of the number of lymph node metastases compared with the pathologic nodal stage (pN category) based on the anatomic extent of lymph node metastases in TNM classification of non-small cell lung cancer. METHODS We reviewed 1,081 patients who underwent major pulmonary resection and(More)
BACKGROUND This study focused on the association between preoperative serum C-reactive protein (CRP) levels and pathologic parameters in patients with resected non-small cell lung cancer (NSCLC). Our primary objective was to find pathologic factors that may explain poor prognosis in patients with preoperative serum CRP elevation. METHODS The records of(More)
PURPOSE To investigate the frequency and the prognostic role of fibroblast growth factor receptor 1 (FGFR1) amplification in patients with surgically resected squamous cell carcinoma of the lung (SCCL) and the association between smoking and FGFR1 amplification. PATIENTS AND METHODS Gene copy number of FGFR1 was investigated in microarrayed tumors from(More)
Recent work has shown that peroxisome proliferator-activated receptor beta (PPARbeta) attenuates cell proliferation and skin carcinogenesis, and this is due in part to regulation of ubiquitin C expression. In these studies, the role of PPARbeta in modulating ubiquitin-dependent protein kinase Calpha (PKCalpha) levels and phosphorylation signaling pathways(More)
OBJECTIVE To assess the feasibility and safety of robot-assisted thoracoscopic esophagectomy for esophageal cancer in the prone position. METHODS Twenty-one patients underwent robot-assisted thoracoscopic esophagectomy in the prone position by a surgical oncologist who had no prior experience with thoracoscopic esophagectomy. Hemodynamic and respiratory(More)
BACKGROUND Advances in local treatments for hepatocellular carcinoma (HCC) have seen better prognosis. There were few studies on surgery for pulmonary metastasis from HCC controlled by local treatment. This study was conducted to analyze prognostic factors after surgery for pulmonary metastasis from HCC. METHODS We reviewed 32 patients who underwent(More)
OBJECTIVE Prognosis of primary thymic carcinomas is poor due to advanced stage progression at diagnosis and highly malignant behavior. We retrospectively evaluated patients with thymic carcinoma to determine the prognostic factors. METHODS Sixty patients diagnosed and treated for thymic carcinoma from 1986 to 2005 were reviewed retrospectively. Influences(More)
Growth factor receptor (GFR) signaling controls epithelial cell growth by responding to various endogenous or exogenous stimuli and subsequently activating downstream signaling pathways including Stat3, PI3K/Akt/mTOR, MAPK, and c-Src. Environmental chemical toxicants and UVB irradiation cause enhanced and prolonged activation of GFR signaling and downstream(More)
Human papillomavirus (HPV) infection is a co-carcinogen of lung cancer and contributes to its pathogenesis. To evaluate the prevalence of HPV infection, polymerase chain reaction (PCR) was employed to detect HPV 16, 18, and 33 DNA in tumor tissues of 112 patients with non-small cell lung cancer (NSCLC) who underwent curative surgery from Jan. 1995 to Dec.(More)
BACKGROUND Although the survival benefit of adjuvant chemotherapy for nonsmall-cell lung cancer has been proved, 50% to 86% of patients received all planned cycles of chemotherapy. A thoracoscopic procedure may enable more effective administration of adjuvant chemotherapy than a thoracotomy. However, a well-balanced comparison is lacking. METHODS Patients(More)
