Prostate Cancer

NEW YORK-Expression of prostate-specific antigen (PSA) in the messenger RNA (mRNA) of pelvic lymph nodes appears to be a promising marker for occult micrometastases in patients with localized prostate cancer, said Anna C. Ferrari, MD, assistant professor, Medical Oncology Associates of the Derald R. Ruttenberg Cancer Center, Mount Sinai School of Medicine, New York.

The report by Hanks and colleagues examines two controversial issues that are related to the treatment of prostate cancer with external-beam radiotherapy: (1) the outcome of younger vs older men, and (2) the relative risk of relapse with follow-up beyond 5 years. The findings of their study are important not only in addressing these points, but also because they shed light on another concern often raised by urologists.

In this issue of ONCOLOGY, Dr. Hanks further establishes his legacy by leading the charge for radiotherapy as the treatment of choice in men with clinically localized prostate cancer. Most urologists and some radiation oncologists tend to consider

A study was undertaken to evaluate the question of cure in "young" men with prostate cancer treated by external-beam radiation. Results in young men (£ 65 years) were compared to older men. Biochemical freedom from failure was examined to 10 years’ follow-up, and hazard functions for failure vs time were reported. Results show that prostate cancer patients are cured by external-beam radiation and that there is no difference in results for young or older men. Few failures occur after 5 years’ follow-up and the percentage cured is similar to that with prostatectomy, with much less morbidity. Appropriate dose is necessary to optimize outcome.

Dr. Small is associate professor of medicine and of urology and co-director of the UCSF/Mt. Zion Urologic Oncology Program.

BOSTON-Men are far more likely to be diagnosed with prostate cancer today than 2 decades ago, and they have more aggressive treatment options. Is their chance of dying of the disease dropping as a result? It is too early in the era of prostate-specific antigen (PSA) testing to tell, keynote speaker Michael J. Barry, MD, said at the 42nd Annual Meeting of the American Society for Therapeutic Radiology and Oncology .

BOSTON-Investigators at Johns Hopkins University School of Medicine are testing a common cold virus as a vector for gene therapy against prostate cancer, Theodore L. DeWeese, MD, reported at the 42nd annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO). The therapy was found to be safe, and the technique showed signs of antitumor activity in a phase I trial.

CHICAGO-The permanent placement of radioactive seeds in the prostate gland is proving to be equivalent to radical prostatectomy in the treatment of men with prostate cancer, according to some recently published data. However, some men have been reluctant to choose this treatment option because of the chance that the seeds may expose family members to excessively high radiation doses.

Prostate cancer is now the most commonly diagnosed noncutaneous neoplasm in men.[1] While there are many questions of profound clinical significance related to the management of this neoplasm, few are as critical as those regarding the limitations of current imaging modalities for clinicians involved in the management of these patients. As such, the thorough, if somewhat depressing, overview of the current status of imaging in prostate cancer by El-Gabry et al provides timely insight into both where we are and where we need to go.

The authors have done an excellent job of preparing a complete and unbiased review of various imaging modalities that are currently available or being developed for the evaluation of patients with carcinoma of the prostate. In addition to the review of the literature, the authors have succinctly summarized the technical details that allow the uninitiated to understand the basic principles of these imaging technologies.

Various treatment options are available for adenocarcinoma of the prostate-the most common malignant neoplasm among men in the United States. To select an optimum management strategy, we must be able to identify an organ-confined disease (in which local therapy such as surgery or radiation may be beneficial) vs prostate cancer beyond the confines of the gland (for which other treatment approaches may be more appropriate). At present, no standard imaging modality can by itself reliably diagnose and/or stage adenocarcinoma of the prostate. Standard transrectal ultrasound, magnetic resonance imaging (MRI), computed tomography, bone scans, and plain x-ray are not sufficiently reliable when used alone. Fortunately, advances in imaging technology have led to the development of several promising modalities. These modalities include color and power Doppler ultrasonography, ultrasound contrast agents, intermittent and harmonic ultrasound imaging, MR contrast imaging, MRI with fat suppression, MRI spectroscopy, three-dimensional MRI spectroscopy, elastography, and radioimmunoscintigraphy. These newer imaging techniques appear to improve the yield of prostate cancer detection and staging, but are limited in availability and thus require further validation. This article reviews the status of current imaging modalities for prostate cancer and identifies emerging imaging technologies that may improve the diagnosis and staging of this disease.

The fastest growing segment of the US population is the group over the age of 65 years. In the next 30 years, this group will comprise over 20% of the population. Because 60% of all cancers occur in this age group, there will be an expected rise in the total cancer burden.

The world’s population is aging. Older age is associated with an increase in the incidence of cancer, especially cancer of the breast, lung, prostate, and colon. The management of older patients with cancer is biased by the
