BACKGROUND Although cigarette smoking is the major risk factor for lung cancer, only 7% of female lung cancer patients in Taiwan have a history of smoking. The genetic mechanisms of carcinogenesis in nonsmokers are unclear, but semaphorins have been suggested to play a role as lung tumor suppressors. This report is a comprehensive analysis of the molecular(More)
Thymic carcinoma is a rare neoplasm with extremely poor prognosis. To evaluate the outcome of treatment in thymic carcinoma, we reviewed a 10-year (1982 to 1992) experience with 20 consecutive patients in Taichung Veterans General Hospital. There were 9 men and 11 women: ages ranged from 34 to 70 years old (mean 51.4 years). None of these patients had(More)
Increasing evidence suggests that PRMT5, a protein arginine methyltransferase, is involved in tumorigenesis. However, no systematic research has demonstrated the cell-transforming activity of PRMT5. We investigated the involvement of PRMT5 in tumor formation. First, we showed that PRMT5 was associated with many human cancers, through statistical analysis of(More)
The aim of this study was to elucidate the occurrence of DNA sequence changes in the promoter region of hTERT gene, and its effect on telomerase expression and telomere length maintenance in non-small cell lung cancer (NSCLC). Between January 2002 and December 2003, 66 NSCLC patients were studied. The expression of hTERT, telomerase activity (TA), and c-Myc(More)
One individual with two or three malignant neoplasms is not uncommon. However, a patient with more than 5 primary malignancies is unusual. We present a 51-year-old female who developed 6 metachronous primary malignant neoplasms in a period of 10 years. The anatomic sites of neoplasms in this patient included the cervix, larynx, skin, left breast, bladder(More)
Curcumin is a natural compound that has been extensively observed due to its potential as an anticancer drug. Curcumin restrains cancer cell progression via telomerase activity suppression. However, the exact mechanism is still unknown. In this study, we demonstrate that the effects of curcumin on cell viability and telomerase activity can be blunted by(More)
OBJECTIVES To demonstrate gastroesophageal reflux induced by proximal gastrectomy and to report preventive measures, such as total gastrectomy followed by Roux-en-Y esophagojejunostomy. METHODS Thirteen patients underwent proximal gastrectomy (PG), and six patients underwent total gastrectomy (TG). Two of the 13 patients who received PG later underwent(More)
BACKGROUND Spontaneous hemopneumothorax, defined as the accumulation of more than 400 mL of blood in the pleural cavity in association with spontaneous pneumothorax, is a rare entity occurring in young patients and may be life threatening. Although many reports of case studies and series have been published in the world literature, the lack of consistent(More)
The clinical significance of HPV-16/18 E6 oncoprotein expression in non-small cell lung cancer (NSCLC) is not fully known. A study was undertaken to investigate the association between expression of human papillomavirus 16/18 E6 oncoprotein and survival in patients with stage I NSCLC. We analyzed a series of 217 patients with stage I NSCLC for the presence(More)
BACKGROUND It has been demonstrated that the deletion, mutation, hypermethylation and subcellular location of the tumor suppressor phosphatase and tensin homologue (PTEN) are closely correlated with carcinogenesis, progression and prognosis of malignancy. Both mutation and the microsatellite instability of the PTEN gene influence regulation of the PI3K/Akt(More)
