Prostate cancer clinical stage does not predict recurrence

22.11.2010
A new study challenges the current staging system that determines the extent or severity of prostate cancer that has not metastasized.

Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study found that there is no link between localized prostate cancer's clinical stage and a patient's risk of cancer recurrence after having his prostate removed.

One of the primary purposes of staging prostate cancers is to help physicians determine a patient's prognosis. For example, a more advanced clinical stage should indicate a higher risk of cancer recurrence after treatment. Surprisingly, however, researchers have found that clinical stage is of questionable utility for predicting disease recurrence after surgical removal of the prostate (radical prostatectomy) in patients with localized prostate cancer.

Adam Reese, MD, of the University of California, San Francisco, and his colleagues questioned whether staging errors are responsible for this discrepancy. In other words, do physicians often inaccurately stage prostate cancer cases, and if so, does this account for the inconsistent reliability of clinical staging for predicting prostate cancer outcomes?

The investigators found that clinical stage was assigned incorrectly in 35.4 percent of 3,875 men in a multi-institutional national disease registry. The majority of these staging errors occurred because physicians frequently disregarded the results of transrectal ultrasound tests and incorrectly incorporated biopsy results when assigning stage.

Even after correcting these staging errors, however, there was no association between clinical stage and prostate cancer recurrence after radical prostatectomy. "Our findings question the utility of our current staging system for localized prostate cancer," said Dr. Reese.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
