BACKGROUND At diagnosis, most small-cell lung cancers (SCLCs) are chemosensitive, whereas non-small-cell lung cancers (NSCLCs) are usually chemoresistant. Activation of ras genes and HER-2/neu genes (also known as ERBB2) is encountered in subpopulations of NSCLC but not in SCLC and has been linked to shortened survival. Therefore, activation of these genes(More)
STUDY OBJECTIVE A cancer registry was analyzed to determine if the clinicopathologic characteristics, treatment modalities, and prognosis of non-small cell lung cancer (NSCLC) patients < 40 years of age at diagnosis differed from patients > 80 years of age at diagnosis. DESIGN Retrospective review of patients with NSCLC diagnosed between 1987 and 1996. (More)
OBJECTIVES Foreign body aspiration into the lower airway in adults is uncommon. We designed this study to investigate the clinical presentations, precipitating factors, management choice, and complications of foreign body aspiration in Chinese adults. PATIENTS AND METHODS We analyzed 43 consecutive adult patients with foreign body aspiration between(More)
PURPOSE A phase II randomized study was conducted to evaluate the efficacy and toxicity of gemcitabine (GEM) versus the combination of cisplatin and etoposide (EP) in Chinese patients with inoperable (stage III or IV) non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS From March 1995 to February 1996, 53 patients were enrolled onto the study: 27(More)
Smoking cessation is an arduous process because nicotine withdrawal syndrome, which occurs following sudden interruption of nicotine use in long-term smokers, frequently prevents them from giving up the habit. Nicotine supplement systems may relieve smokers' nicotine withdrawal symptoms and, thus, help in the process of abstinence from smoking. The purpose(More)
This study examined the effects of p53 gene status on DNA damage-induced cell death and chemosensitivity to various chemotherapeutic agents in non-small cell lung cancer (NSCLC) cells. A mutant p53 gene was introduced into cells carrying the wild-type p53 gene and also vice versa to introduce the wild-type p53 gene into cells carrying the mutant p53 gene.(More)
Using a panel of 20 non-small cell lung cancer (NSCLC) cell lines established from previously untreated patients, we investigated the relationships between intrinsic chemoresistance (to four agents used commonly in the therapy of NSCLC) and HER-2/neu gene expression (which encodes glycoprotein p185neu), p53 gene mutations, and cell proliferation(More)
The HER-2/neu gene product, p185(neu), is a membrane-bound receptor with tyrosine kinase activity. High levels of p185(neu) is correlated with intrinsic chemoresistance of non-small cell lung cancer (NSCLC) cell lines. We investigated the effects of tyrphostin AG825, a selective tyrosine kinase inhibitor preferentially inhibiting HER-2/neu kinase, on the(More)
4 patients with advanced non-small-cell lung cancer (NSCLC) treated with docetaxel developed life-threatening pneumonitis requiring mechanical ventilation. Docetaxel (30–60 mg m–2, according to a different protocol) was infused within one hour with standard premedications. One patient’s pneumonitis occurred 5 days after the first dose of docetaxel, and that(More)
BACKGROUND Paclitaxel (Taxol) plus carboplatin (PC) has shown activity in the treatment of advanced non-small-cell lung cancer (NSCLC). Non-platinum-containing combination chemotherapy, such as paclitaxel plus gemcitabine (PG), has also demonstrated reasonable efficacy. Our aim here was to evaluate the clinical efficacy and cost-effectiveness of PC versus(More)
