Global alterations in chromatin structure profoundly influence gene expression in thoracic neoplasms, silencing tumor suppressors while facilitating the expression of various cancer testis antigens such as NY-ESO-1. Although recent studies have shown that histone deacetylase inhibitors can potentiate tumor suppressor gene induction mediated by demethylating(More)
OBJECTIVE As thoracoscopic lobectomy becomes widely applied for treatment of non-small cell lung cancer, thoracoscopic segmentectomy remains controversial for patients with small stage I lung cancers. Questions remain regarding safety, morbidity, mortality, and recurrence rate. This study compared outcomes between thoracoscopic segmentectomy and lobectomy.(More)
BACKGROUND Pneumonectomy is associated with a significant incidence of perioperative morbidity and mortality. The purpose of this study is to identify the risk factors responsible for adverse outcomes in patients after pneumonectomy utilizing The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTDB). METHODS All patients who had(More)
BACKGROUND Thoracoscopic lobectomy is performed with increasing frequency for early-stage lung cancer. Several published reports suggest thoracoscopic resection is safe, with the potential advantage of shorter hospital stay, quicker recovery, and comparable oncologic results. METHODS Data on 180 video-assisted thoracoscopic surgery (VATS) patients who(More)
OBJECTIVE Although paclitaxel is widely used as a systemic agent for the treatment of solid tumors, limited information is available concerning administration of this taxane by regional techniques. The present study was undertaken to evaluate the pharmacokinetics and acute toxicity of paclitaxel administered by hyperthermic retrograde isolated lung(More)
BACKGROUND Diaphragm pacing (DP) can replace mechanical ventilation in tetraplegics and in trials has assisted respiration in amyotrophic lateral sclerosis patients. This report describes results of DP in patients with cardiac pacemakers. METHODS Prospective, single-center and multicenter, nonrandomized, controlled, interventional protocols under U.S.(More)
Although SV40 oncoproteins have been detected in malignant pleural mesotheliomas (MPMs), their role in the pathogenesis and clinical behavior of these neoplasms remains controversial. In the present study, we sought to define the relevance of SV40 T/t antigen expression in established human mesothelioma cell lines deficient for p16INK4a as well as ARF(More)
BACKGROUND Although MAGE-3 has been detected in approximately 40% of lung and esophageal cancers, expression of this cancer testis antigen appears to be below the threshold for immune recognition in patients with these malignancies. The aim of this study was to determine if the demethylating agent, 5-Aza-2'-deoxycytidine (DAC) and if the histone deacetylase(More)
BACKGROUND Cancer cells that overexpress c-erbB oncogenes exhibit resistance to chemotherapy, enhanced tumorigenicity, as well as increased propensity for metastasis. The aim of this study was to investigate if depletion of erbB-1/EGFR and erbB-2/HER2neu oncogene products by 17-allylamino 17-demethoxy Geldanamycin (17AAGA) could diminish the metastatic(More)
Airway stenting has been well used in the treatment and palliation of patients with malignant stenoses and to a lesser extent in those with benign disease causing airway compromise. Stents are either constructed of silicone or metal, usually a nitinol, a nickel and titanium alloy. The different categories of stents have positive and negative attributes that(More)
