[Superior Vena Cava Syndrome].

Superior vena cava(SVC)syndrome is a syndrome caused by impaired venous return due to stenosis of the SVC. Most of such cases are due to tumors(non-small cell lungcancer, small cell lungcancer, malignant lymphoma, etc), and the most common cause of SVC syndrome is lungcancer. Symptoms of SVC syndrome are caused by external compression of the SVC, direct invasion, internal thrombus or embolization.

Erlotinib plus bevacizumab versus erlotinib alone in patients with EGFR-positive advanced non-squamous non-small-cell lung cancer (NEJ026): interim analysis of an open-label, randomised, multicentre, phase 3 trial.

Background: Resistance to first-generation or second-generation EGFR tyrosine kinase inhibitor (TKI) monotherapy develops in almost half of patients with EGFR-positive non-small-cell lung cancer (NSCLC) after 1 year of treatment. The JO25567 phase 2 trial comparing erlotinib plus bevacizumab combination therapy with erlotinib monotherapy established the activity and manageable toxicity of erlotinib plus bevacizumab in patients with NSCLC. We did a phase 3 trial to validate the results of the JO25567 study and report here the results from the preplanned interim analysis.

Balloon Dilatation of a Case of Tuberculous Tracheobronchial Stenoses during the Course of Antituberculous Treatment.

We report a case of posttuberculosis (TB) tracheobronchial stenoses presented with progressive exertional dyspnea during the course of anti-TB treatment. An 83-year-old Japanese man was admitted for progressive dyspnea; chest X-ray and CT showed stenosis of distal trachea and left main bronchus. Pulmonary function test revealed reduction of FEV1.

Phase I and pharmacokinetic study of combination chemotherapy using irinotecan and paclitaxel in patients with lung cancer.

The purpose of this study was to investigate the maximum tolerated doses, dose-limiting toxicities, efficacy, and pharmacokinetic profiles in the combination of irinotecan and paclitaxel. Eligibility criteria included age 75 years or younger, good performance status, adequate organ function, and unresectable non-small cell or extensive disease of small cell lung cancer. Irinotecan was administered on days 1 and 8 over 90 minutes, and paclitaxel was administered on day 8 over 3 hours after 90 minutes from the end of the irinotecan infusion.

Influence of histological type, smoking history and chemotherapy on survival after first-line therapy in patients with advanced non-small cell lung cancer.

The usual primary endpoint in clinical trials for first-line chemotherapy in advanced non-small cell lung cancer is overall survival. Second-line chemotherapy can also prolong overall survival. Non-smoking history has been associated with a treatment effect for epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) versus placebo for overall survival.

Phase II study of weekly paclitaxel for relapsed and refractory small cell lung cancer.

The purpose of this study was to evaluate the efficacy and toxicity of single-agent paclitaxel given weekly to patients with relapsed and refractory small cell lung cancer (SCLC). Patients were treated with 80 mg/m2 paclitaxel administered weekly for 1 h for 6 weeks in an 8-week cycle. Twenty-two patients were enrolled, 21 of whom were eligible.

Pharmacokinetic and pharmacodynamic study of IST-622, a novel synthetic derivative of chartreusin, by oral administration in a phase II study of patients with breast cancer.

The aim of this study was to analyze the pharmacokinetics and pharmacodynamics (PK/PD) of 6- O-(3-ethoxypropionyl)-3',4'- O-exo-benzylidene-chartreusin (IST-622) and its metabolites, and to develop limited sampling models (LSM). Based on the data from 18 patients with breast cancer who were treated orally with 280 or 525 mg/m(2) of IST-622 once daily after breakfast for five consecutive days, we analyzed the relationship between the area under the plasma concentration versus time curve (AUC) and toxicities using a sigmoid E-max model and logistic regression. Plasma concentrations of IST-622 and its metabolites, 3',4'- O-exo-benzylidene-chartreusin (A-132) and 3"-demethyl-3',4'- O-exo-benzylidene-chartreusin (A-132M), were measured at 1, 2, 4, 8 and 24 h after administration on day 1.
