UMHS study links gonorrhea, prostate cancer in men

10.05.2004


Many sexual partners, history of gonorrhea seen as risks for prostate cancer



Men who have had gonorrhea are more likely to be diagnosed with prostate cancer, new research from the University of Michigan Health System finds.

Having more than 25 lifetime sexual partners also increases odds of prostate cancer, by more than 2.5 times that of men with five or fewer sexual partners, the study found.


The conclusions are part of the Flint Men’s Health Study, a population-based study of black men ages 40-79 who live in Flint, Mich. The research will be presented May 9 at the American Urological Association annual meeting in San Francisco.

The Flint Men’s Health Study looked at African-American men as part of an effort to determine why black men are twice as likely as white men to develop prostate cancer and twice as likely to die from the disease.

Researchers asked 703 black men without prostate cancer and 129 black men with prostate cancer about their number of sexual partners, age at first intercourse, frequency of sexual activity and history of sexually transmitted diseases.

"Our results suggest gonorrhea may play a role in the development of prostate cancer in African-American men. Although we are unable to show that gonorrhea directly causes prostate cancer, we suspect the inflammatory effect of the gonorrhea infection may trigger pre-existing cancerous cells to multiply," says lead study author Aruna Sarma, Ph.D., assistant research scientist in the Department of Urology at U-M Medical School.

In the study, 65 percent of the men with prostate cancer reported having had gonorrhea, compared to 53 percent of men without prostate cancer. Men with prostate cancer were also more likely to report being diagnosed more than once with gonorrhea, a bacterial infection transmitted through sexual intercourse.

Other researchers have proposed a possible link between sexually transmitted diseases and prostate cancer. Previous studies have found a decreased risk of prostate cancer among men who use condoms and some evidence linking prostate cancer and various STD’s.

In addition, the human papillomavirus, another common sexually transmitted disease, has been shown to cause cervical cancer in women. Scientists believe the cervical cancer develops in reaction to the inflammation caused by the HPV infection, a similar theory to why gonorrhea may play a role in prostate cancer.

Further studies are needed to determine whether gonorrhea or other STD’s actually cause prostate cancer, the researchers say.

In addition to Sarma, study authors were Kathleen Cooney, M.D., from the U-M departments of Internal Medicine and Urology; John Wei, M.D., and James Montie, M.D., from Urology; David Schottenfeld, M.D., from Epidemiology and Internal Medicine; Steven Jacobsen from the Mayo Clinic; and U-M research associates Julie McLaughlin and Rodney Dunn.


The Flint Men’s Health Study was funded by a U-M Specialized Program of Research Excellence, or SPORE, grant in prostate cancer from the National Institutes of Health.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
