Early Impressions of High-Intensity Focused Ultrasound for Prostate Cancer

February 01, 2008

The use of high-intensity focused ultrasound (HIFU) as a method for ablation of a localized tumor growth is not new. Several attempts have been made to apply the principles of HIFU to the treatment of pelvic, brain, and gastrointestinal tumors. However, only in the past decade has our understanding of the basic principles of HIFU allowed us to further exploit its application as a radical and truly noninvasive, intent-to-treat, ablative method for treating organ-confined prostate cancer. Prostate cancer remains an elusive disease, with many questions surrounding its natural history and the selection of appropriate patients for treatment yet to be answered. HIFU may play a crucial role in our search for an efficacious and safe primary treatment for localized prostate cancer. Its noninvasive and unlimited repeatability potential is appealing and unique; however, long-term results from controlled studies are needed before we embrace this new technology. Furthermore, a better understanding of HIFU's clinical limitations is vital before this treatment modality can be recommended to patients who are not involved in well-designed clinical studies. This review summarizes current knowledge about the basic principles of HIFU and its reported efficacy and morbidity in clinical series published since 2000.

Pathologic Evaluation of Prostatic Carcinoma: Critical Information for the Oncologist

April 01, 1996

The pathologist plays an integral role in the evaluation and treatment of many urologic cancers. Prostate cancer may be the best example of the importance of the pathologist in providing accurate clinical staging. Dr. Epstein has written an excellent review of the critical pathologic information available from prostate needle biopsy and radical prostatectomy specimens. The article highlights how to utilize this information in day-to-day clinical practice. Although the article is complete, some areas deserve special attention.
