PURPOSE: We summarize the literature addressing factors that influence treatment decisions made by men with prostate cancer. MATERIALS AND METHODS: A MEDLINE search of the English language literature published between 1969 and 2000, using the combined MESH key words "prostatic neoplasms," "patient participation," "Internet" and "decision making," generated 181 abstracts. Only 23 of these publications addressed factors influencing treatment decisions made by men with prostate cancer. Nine additional relevant studies were identified from references in the original 23 articles. Subsequently a search for the term "prostate cancer" using several popular Internet search engines yielded more than 1 million hits. A further search was performed using the key words "prostate cancer" and "prostate" within on-line archives of the United Kingdom television channels BBC, ITV, and channels 4 and 5, and newspapers The Sun, The Daily Mail, The Observer, The Guardian and The Times. RESULTS: When there is poor quality evidence or little professional consensus to support a particular treatment over another, no clinical guidelines regarding treatment are possible. Patients are faced with a series of options, and the data reveal that the process of choosing between these options is based on input from a large number of sources. These sources differ in the way that benefits of treatment are emphasized over harms and vice versa. We identified little evidence regarding which type of input exerts the greatest influence on patients. It may be that the sources associated with the most bias have the greatest influence. CONCLUSIONS: There is a paucity of information on how patients with prostate cancer use different types of input in the treatment decision making process. The physician, as principal caregiver, still appears to have the most direct influence on patient choice. Just how long this status will continue is uncertain.

The compact disc (CD) is an ideal toolfor reading, writing, and storing numeric information. It was used in this work as a support for constructing DNA microarrays suited for genomic analysis. The CD was divided into two functional areas: the external ring of the CD was used for multiparametric DNA analysis on arrays, and the inner portion was usedfor storing numeric information. Because polycarbonate and CD resins autofluoresce, a colorimetric method for DNA microarray detection was used that is well adaptedfor the fast detection necessary when using a CD reader. A double-sided CD reader was developed for the simultaneous analysis of both array and numeric data. The numeric data are engraved as pits in the CD tracks and result in the succession of 0/1, which results from the modulation of the laser reflection when one reads the edges of the pits. Another diffraction-based laser was placed above the CD for the detection of the DNA targets on the microarrays. Both readersfit easily in a PC tower. Both numeric and genomic information data were simultaneously acquired, and each array was reconstituted, analyzed, and processed for quantification by the appropriate software.
