This is a well-written and timely review of a topic that has recently become both complex to urologists and confusing to nonurologists. The authors discuss the physiology of prostate-specific antigen (PSA) and its role in a variety of clinical situations, highlighting the areas of proven utility and identifying areas of controversy.
Despite the impact of prostate-specific antigen (PSA) testing on the detection and management of prostate cancer, controversy about its usefulness as a marker of disease activity continues. This review, based on a
NEW YORK-Eligard 7.5 mg (leuprolide acetate for injectable suspension) is now commercially available for the palliative treatment of advanced prostate cancer, Sanofi-Synthelabo Inc. announced in a news release. The new formulation of the
PRINCETON, New Jersey-Cytogen Corporation’s ProstaScint (capromab pendetide) is being evaluated in a phase I/II clinical study for its utility in helping guide intensity modulated radiation therapy (IMRT) for prostate cancer.
Sanofi-Synthelabo announced the commercial availability of Eligard (leuprolide acetate, 7.5 mg) for the palliative treatment of advanced prostate cancer at the 2002 annual meeting of the American Urological Association. Recommended in the prostate
Prostate cancer represents the most common neoplasm and second leading cause of cancer mortality among men in the United States. There are 189,000 new cases of prostate cancer and 32,000 deaths resulting from prostate cancer expected in 2002.[1]
ATLANTA-Dynamic magnetic resonance imaging (MRI) may be able to detect recurrent prostate cancer after prostatectomy when the patient has a negative biopsy but a rising prostate-specific antigen (PSA) level.
Most Men Don’t Need Yearly PSA Screening: PLCO Study
SAN FRANCISCO-Curcumin, the active ingredient in the spice turmeric, can act together with the natural molecule TRAIL to increase apoptosis in androgen-sensitive human prostate cancer cells, researchers said at the 93rd Annual Meeting of the American Association for Cancer Research (abstract 4237).
A study conducted by researchers at Duke University and Johns Hopkins Medical Centers and published in the journal Cancer (94:987-996) found that the use of indium-111-capromab pendetide (ProstaScint), a radiolabeled monoclonal antibody imaging agent, allowed identification of recurrent prostate cancer earlier than conventional imaging methods, such as the computed tomography (CT) scan. Prostate cancer recurs in nearly 40% of patients, and about 11% are at high risk for metastatic spread of the disease. Conventional imaging methods are often only able to detect a more advanced stage of prostate cancer.
NEW YORK-The final report of a phase II study suggests that the early addition of 13-cis-retinoic acid (isotretinoin, Acutane) to hormone therapy may enhance PSA responses in advanced androgen-dependent prostate cancer. Anna C. Ferrari, MD, of Mt. Sinai School of Medicine, New York, presented the results at the Chemotherapy Foundation Symposium XIX (abstract 58).
Docetaxel (Taxotere)-based regimens can be included among the most effective treatment options for the management of patients with advanced, androgen-independent prostate cancer. Results with docetaxel as a single agent and in combination regimens with estramustine (Emcyt) have consistently achieved a palliative response, reduced serum PSA levels by 50% or more, and produced objective responses in patients with measurable disease. In addition, encouraging survival data have been demonstrated in several phase II trials.
Men underestimate their chance of developing prostate cancer even when they are considered "at risk" for the disease, according to a new study conducted by researchers at the Fox Chase Cancer Center in Philadelphia. The findings were
BALTIMORE-A single injection of FK506 (Prograf) or a similar immunophilin drug at the time of surgery might prevent impotence in men undergoing nerve-sparing prostatectomy for localized prostate cancer, according to preclinical work reported in Nature Medicine (7:1073-1074, 2001) by Sena F. Sezen, PhD, and colleagues at the Johns Hopkins Medical Institutions.
WASHINGTON-Twice as many black as white men prefer not to know that they have prostate cancer, and two thirds believe that it is a "death sentence" with a treatment "worse than the disease," according to a study reported by Allyson Schifano, MPH, CHES, at the 8th Biennial Symposium on Minorities, the Medically Underserved, and Cancer.
PALO ALTO, California-Varian Medical Systems has released VariSeed 7.0, the company’s newest treatment planning software for permanent seed implant brachytherapy used in treating prostate cancer. VariSeed 7.0 gives physicians the ability to use real-time images generated during the implant procedure to deliver precise accurate doses, the company said in a news release.
I read with interest the article by Hanks and colleagues-and the reviews that followed-on the evidence for cure in prostate cancer.
The multistep process of carcinogenesis, which can take many years, provides many opportunities for intervention to inhibit disease progression. Effective chemoprevention agents may reduce the risk of cancer by inhibiting the initiation stage of carcinoma through induction of apoptosis or DNA repair in cells harboring mutations, or they may act to prevent promotion of tumor growth. Similarly, chemoprevention may entail blocking cancer progression to an invasive phenotype.
WASHINGTON-Surgeons have historically had a "feeling that black men are at the highest risk" of bad outcomes in prostate cancer, said Christopher R. Porter, MD, professor of urology, Stony Brook Hospital Medical Center, Stony Brook, New York. Their risk of dying from the disease is twice that of white men, and their risk of developing it is 1.7 times higher.
WASHINGTON-Black men historically have some of the world’s worst rates of prostate cancer incidence and mortality, with prognostic features significantly worse than those of white Americans.
BOSTON-Excessive sun exposure is a known risk factor for the development of skin cancer, but sun exposure appears to have a protective effect against a variety of other cancers, according to speakers at a symposium on sunlight at the 168th National Meeting of the American Association for the Advancement of Science (AAAS).
STANFORD, Calif-Attempts to reduce prostate cancer mortality by ordering biopsies at ever-lower prostate-specific antigen (PSA) levels are driving up health care costs and subjecting thousands of men to early prostatectomies they could safely defer for years, according to researchers at Stanford University Medical Center.
ROCKVILLE, Maryland-Members of the Oncologic Drugs Advisory Committee (ODAC) have unanimously recommended that the Food and Drug Administration approve Zometa (zoledronic acid for injection, Novartis) for the treatment of bone metastases in patients with multiple myeloma and breast cancer, prostate cancer, lung cancer, and other solid tumors.
CHICAGO-Nerve-sparing prostatectomy has become increasingly common as younger men diagnosed with prostate cancer seek to preserve erectile function. Although postoperative radiotherapy has improved control of prostate cancer, few studies have examined its effect on erectile function.
The use of complementary and alternative medicine is a well-known phenomenon among cancer patients, and prostate cancer patients are no exception. The review article by Drs. Das and Kaplan nicely summarizes most of the data available on the use of PC-SPES, selenium, and vitamin E by prostate cancer patients. These three agents are probably the most widely used complementary approaches in prostate cancer, and they are the ones that have been studied most extensively. However, true data on efficacy, careful toxicity analyses, dose-response analysis, or pharmacokinetic analyses of these agents are extremely limited.
