Breast cancer in men is a rare disease, accounting for approximately 1% of all breast cancer cases. Although the epidemiologic literature regarding female breast cancer is extensive, relatively little is known about the etiology of male breast cancer (MBC). This review is intended to summarize the existing body of evidence on genetic and epidemiologic risk(More)
Of the limited number of epidemiological investigations on aspirin (and other nonsteroidal anti-inflammatory drugs) and breast cancer, the majority observe a protective role, yet only a few report dose-response effects for frequency or duration of use. We studied aspirin use among 1,478 breast cancer patients diagnosed from 1982 to 1998, and 3,383(More)
Analgesics have been shown to reduce risk for colorectal cancer. Results from three recent reports (D. W. Cramer et al., Lancet, 351: 104-107, 1998; C. Rodriguez et. al., Lancet, 352: 1354-1355, 1998; L. Rosenberg et al., Cancer Epidemiol. Biomark. Prev., 9: 933-937, 2000) suggest that these drugs might be associated with decreased risk for ovarian cancer.(More)
We have used genome-wide allelotyping with 348 polymorphic autosomal markers spaced, on average, 10 cM apart to quantitate the extent of intrachromosomal instability in 59 human sporadic colorectal carcinomas. We have compared instability measured by this method with that measured by inter-(simple sequence repeat) PCR and microsatellite instability assays.(More)
It has been hypothesized that aspirin and other nonsteroidal anti-inflammatory drugs can decrease the risk of developing prostate and other cancers, although observational studies have not been very conclusive. The current study examined the effects of regular aspirin use on prostate cancer risk in 1,029 patients with primary, incident cancer of the(More)
Although a large number of epidemiological studies have examined the role of aspirin in the chemoprevention of colon cancer and other solid tumors, there is a limited body of research focusing on the association between aspirin and lung cancer risk. We conducted a hospital-based case-control study to evaluate the role of regular aspirin use in lung cancer(More)
In the planning of future intervention trials using chemopreventive agents against lung cancer, it is critical to evaluate the effect on biomarkers implicated specifically in lung carcinogenesis. With the use of the H520 and H522 human lung cancer cell lines, the present study showed that treatment with selenium (in the form of methylseleninic acid)(More)
Because of adverse effects of uremia in the innate and adaptive immune systems, we hypothesized that chronic kidney disease (CKD) patients would have higher prevalence of moderate periodontitis compared with individuals without CKD. We examined this hypothesis using the NHANES III dataset, including 12,081 adults stratified by Race-Ethnicity. We followed(More)
Clinical practice guidelines derived from genetic research using population-based biobanks could dramatically change the nature of personal and public health medicine. Centralized population-based biobanks have been established or proposed in at least nine countries to date, and many lessons have been learned from these landmark developments. Scientific and(More)
Based on suggestive findings from a recent study of high-risk Japanese patients, we sought to determine whether the risk of colorectal polyps associated with smoking may be modified by daily use of aspirin in an analysis of a large US screening population. This is a cross-sectional study of 2,918 consecutive colonoscopy patients at a university hospital(More)
