Little epidemiologic research has been done on the etiology of gallbladder cancer (GC). This cohort study was undertaken to examine whether there is an association between parity and risk of death from GC. The study cohort consisted of 1,292,462 women who had a first and singleton childbirth between 1 January 1978 and 31 December 1987. We tracked each woman(More)
BACKGROUND AND AIM The present study was undertaken to examine whether there is an association between parity and age at first birth and risk of liver cancer. METHODS The study cohort consisted of 1,292,462 women who had a first and singleton childbirth between 1 January 1978 and 31 December 1987. We tracked each woman from the time of their first(More)
OBJECTIVES ARID1A is a recently identified tumor suppressor participating in chromatin remodeling. Somatic inactivating mutations of ARID1A and loss of its expression occur frequently in ovarian clear cell and endometrioid carcinomas and in uterine endometrioid carcinomas. Because endometriotic epithelium is thought to be the cell of origin of most ovarian(More)
ARID1A is a recently identified tumor suppressor that functions in chromatin remodeling. Inactivating mutations of ARID1A and loss of its expression most frequently occur in ovarian clear cell carcinoma, ovarian endometrioid carcinoma, and uterine endometrioid carcinoma. In this study, we performed a detailed immunostaining analysis of ARID1A in 246 cases(More)
AT-rich interactive domain 1A (ARID1A) has emerged as a new tumor suppressor in which frequent somatic mutations have been identified in several types of human cancers. Although most ARID1A somatic mutations are frame-shift or nonsense mutations that contribute to mRNA decay and loss of protein expression, 5% of ARID1A mutations are in-frame insertions or(More)
Endoglin, a coreceptor for transforming growth factor β1 (TGF-β1) in vascular endothelial cells, is highly upregulated in tumor vessels and therefore is a specific biomarker for angiogenesis. Some studies have suggested that assessment of tumor angiogenesis may predict cancer response to chemotherapy and radiotherapy. In this study, we attempted to analyze(More)
The relationship between mortality attributed to ovarian cancer and exposure to ambient air pollutants was examined using an ecological design. The study areas consisted of 61 municipalities in Taiwan. Air quality data for recorded concentrations of fine particulate matter (PM2.5) from study municipalities for 2006-2009 were obtained as a marker of traffic(More)
OBJECTIVE   This study was undertaken to examine whether there is a protective effect of grand multiparity on the risks of death from hormone-dependent cancers. METHODS   The study cohort consisted of 144 922 women with at least five children (grand multiparous (GM) women) in the Birth Register between 1 January 1978 and 31 December 1987. Standardised(More)
OBJECTIVES The abdominopelvic cavity is one of the common sites for extrapulmonary tubercular infections. The rate of preoperative misdiagnoses between peritoneal tuberculosis (TB) and ovarian cancer is high because of overlapping nonspecific signs and symptoms. We attempted to analyze the experience within our hospital so as to establish the best means of(More)
OBJECTIVE The aim of this study was to investigate whether the use of statins was associated with breast cancer risk. BACKGROUND Experimental studies have shown that statins have potential protective effects against cancer. METHODS We conducted a population-based case-control study in Taiwan. Cases consisted of all patients who were aged 50 years and(More)
