Analysis of ovarian tumors for the presence of human papillomavirus DNA.

Aim: The role of human papillomavirus (HPV) infection in ovarian tumorigenesis is uncertain. The objective of this study was to screen a collection of ovarian tumors for the presence of high-risk oncogenic HPV types 16, 18 and 33.

Methods: Twenty benign and malignant ovarian tumors were obtained from women undergoing pelvic surgery at a regional comprehensive cancer institution in North America.

Ovarian cancer incidence in the United States, 1992-1999.

Objective: The purpose of this epidemiological study was to report histology-specific age-adjusted ovarian cancer incidence rates that were standardized to the recently adopted year 2000 United States standard population.

Methods: We utilized data gathered from eleven population-based cancer registries of the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute for the years 1992 through 1999. Our analyses included data on 23,484 microscopically confirmed cases of primary malignant ovarian cancer that were diagnosed in women residing in the eleven SEER registries.

Cigarette smoking and the risk of bladder cancer in men and women.

Although cigarette smoking is a principal risk factor for bladder cancer in both men and women, few studies have statistically evaluated whether gender modifies the effect of smoking on bladder cancer risk. We initiated the present case-control study at Roswell Park Cancer Institute in Buffalo, New York, U.S.

Interspecific mitochondrial DNA restriction fragment length polymorphisms in Aspergillus section Flavi.

Mitochondrial DNA restriction fragment length polymorphisms (RFLPs) are described for 64 isolates, representing 11 species of Aspergillus section Flavi. Mitochondrial DNA haplotypes were identified following digestion of total cellular DNA with the restriction enzymes HaeIII, AseI, or DraI. In general, isolates of the same species possessed identical mitochondrial DNA haplotypes.
