BACKGROUND Invasive squamous cell carcinoma (SCC) of the penis is rare in the United States. Although human papillomavirus (HPV) infection is an established etiologic agent in at least 40% of penile SCCs, relatively little is known about the epidemiology of this malignancy. METHODS Population-based data from the National Cancer Institute's Surveillance,(More)
A study of the distribution of some chronic diseases among the Akwesasne Mohawks was performed using computerized medical records of the St. Regis Mohawk Health Services Clinic. Prevalence proportions, annual incidence rates, and five-year incidence rates were computed for the period January 1, 1992 to January 1, 1997 for asthma, diabetes mellitus type II,(More)
BACKGROUND Polychlorinated biphenyls (PCBs) and chlorinated pesticides are endocrine disruptors, altering both thyroid and estrogen hormonal systems. Less is known of action on androgenic systems. OBJECTIVE We studied the relationship between serum concentrations of testosterone in relation to levels of PCBs and three chlorinated pesticides in an adult(More)
BACKGROUND Socioeconomic status (SES) has been associated with melanoma incidence and outcomes. Examination of the relationship between melanoma and SES at the national level in the United States is limited. Expanding knowledge of this association is needed to improve early detection and eliminate disparities. OBJECTIVE We sought to provide a detailed(More)
BACKGROUND Recent research suggests that diabetes, a condition whose incidence is increasing, is associated with exposure to polychlorinated biphenyls (PCBs) and chlorinated pesticides. OBJECTIVES We investigated the potential association between diabetes and serum levels of PCBs, dichlorodiphenyldichloroethylene (DDE), hexachlorobenzene (HCB), and mirex(More)
BACKGROUND In 2016, the cancer registry community will directly assign T, N and M components of stage. The Surveillance, Epidemiology, and End Results program implemented a field study to determine how often T, N and M were not available in the medical record, requiring the registrar to directly assign clinical or pathologic TNM stage components. The field(More)
PCBs are a family of 209 chemical compounds, each of which consists of two benzene rings and 1 to 10 chlorine atoms. Their long-term stability and dispersion into the environment and the food chain have caused concern about their impact on humans and the environment. Native American communities are believed to be at particularly high risk of such exposure(More)
BACKGROUND This report describes the distribution of treatment for cervix uteri, vagina, and vulva carcinomas by demographic characteristics before the widespread implementation of human papillomavirus (HPV) vaccination in the US. METHODS The authors used data collected by the Surveillance, Epidemiology, and End Results Program from 2000 through 2004 to(More)
The American Joint Committee on Cancer, in the eighth edition of its cancer staging manual, makes a number of changes to improve survival predictions in human malignancy. In this commentary, we examine the national collection of data for head and neck cancer. We outline and review the major changes made in head and neck cancer staging, identify the key data(More)
