Genitourinary Cancers

SAN FRANCISCO-A new study supports the hypothesis that calcium consumption is associated with a greater risk of prostate cancer. June M. Chan, ScD, Department of Epidemiology, Harvard School of Public Health, presented the results at the 91st Annual Meeting of the American Association for Cancer Research (AACR).

NEW YORK-A small trial of trastuzumab (Herceptin) alone and with paclitaxel (Taxol) found that the combination was active against prostate cancer, but trastuzumab alone was not. The results were presented at the ASCO meeting by Michael J. Morris, MD, of Memorial Sloan-Kettering Cancer Center.

PHILADELPHIA-Significant benefit can be achieved from long-term androgen suppression following neoadjuvant hormonal cytoreduction and radiotherapy in locally advanced prostate cancer.

Five-year follow-up data presented at the annual meeting of the American Urological Association (AUA) in Atlanta showed that the use of cryoablation as first-line treatment for prostate cancer can be as effective as radiation therapy. The five-center,

MAYWOOD, Ill-Removing the cancerous kidney before administering interferon alfa-2b (Intron A) improves survival in advanced renal cancer, according to results of Southwest Oncology Group (SWOG) Trial 8949. The role of interferon treatment, however, remains controversial.

TORONTO, Canada-A multicenter phase III trial involving more than 250 prostate cancer patients confirmed earlier trials demonstrating that abarelix, a GnRH antagonist, achieved more rapid reduction of testosterone to castrate levels than leuprolide acetate (Lupron) and bicalutamide (Casodex), but did not produce a testosterone surge and clinical flare.

ASCO-Cytoreductive nephrectomy prior to interferon-alfa-2b (Intron A) therapy increased survival by 50% in patients with previously untreated metastatic renal cell cancer, compared with interferon alone, Robert Flanigan, MD, reported at the plenary session of the 36th Annual Meeting of the American Society of Clinical Oncology in New Orleans.

Three-dimensional conformal radiation therapy (3D CRT) is more effective yet costs no more than conventional radiation therapy in the long-term treatment of prostate cancer, according to a study conducted at Fox Chase Cancer Center in

Physicians have long known that male hormones fuel prostate cancer growth. That’s why therapies that block the production of androgen-or testosterone-provide some of the most effective therapies for advanced prostate cancer. Certain drugs, for

FT. LAUDERDALE, Fla-Slight changes in the administration of salvage therapy after radical prostatectomy are among several revisions to the National Comprehensive Cancer Network (NCCN) Practice Guidelines for Prostate Cancer. The revised guidelines recommend radiotherapy for men with positive margins whose prostate-specific antigen (PSA) levels fail to fall to 0 ng/mL after surgery.

The results of an exploratory analysis published in the March 2000 issue of Urology suggest that prolonged combined androgen blockade (CAB) significantly increases survival in patients with advanced prostate cancer.

An estimated 180,400 new prostate cancer cases will be diagnosed in the United States this year, and many of these patients will be diagnosed and treated at community cancer centers.

Despite being one of the more common genitourinary neo plasms, superficial transitional cell carcinoma involving the urinary bladder can be a confusing entity for the treating physician. This confusion stems, in large part, from the binary classification

Baselli and Greenberg have presented a comprehensive overview of intravesical strategies for the management of superficial urothelial malignancies of the bladder, both past and present. A number of points made in the article deserve further

Approximately 54,400 new cases of transitional cell carcinoma of the bladder were reported in the United States in 1999, with an estimated 12,500 deaths attributable to this cancer. Close to 75% of all bladder tumors are confined

The intravesical instillation of therapeutic agents for the treatment of localized bladder cancer began in 1903 when Herring[1] summarized his experience with silver nitrate. Since then, intravesical chemotherapy and immunotherapy have emerged as

CLEVELAND-A program at Travis Air Force Base in California is educating men about the purpose of prostate cancer screening by mailing brochures to the women who use medical services on the base. “This is a novel approach to going after the top men’s cancer,” said Maj. (Dr.) Darryl C. Hunter, medical director of the General Huyser Regional Cancer Center at Travis Air Force Base. He spoke at the 33rd annual meeting of the American Association for Cancer Education.

Hormonal therapy with the goserelin acetate implant (Zoladex) significantly increases overall survival rates in patients with locally advanced prostate cancer when administered at the onset of conventional external irradiation and continued for 3 years.

CHICAGO-A preliminary study of interstitial gene therapy for recurrent prostate cancer shows that transrectal ultrasound can be used effectively for planning delivery of the agent and assessing its initial effects.

Mood disorders may play a role in erectile dysfunction (ED) in prostate cancer patients, according to a report at the Pan American Congress of Psychosocial & Behavioral Oncology. Of 10 prostate cancer patients referred for erectile dysfunction and/or a suspected mood disorder, 7 were diagnosed as having depression and 3 were found to have preexisting relationship problems.

NEW YORK-Erectile dysfunction is a significant factor in decreasing the quality of life (QOL) of prostate cancer patients, according to a report at the Pan American Congress of Psychosocial & Behavioral Oncology.

Immediate antiandrogen therapy after radical prostatectomy and pelvic lymphadenectomy improves survival and reduces the risk of recurrence in patients with node-positive prostate cancer, according to a study published in the December 9, 1999,

WASHINGTON-Medicare now provides coverage for prostate cancer screening. As of Jan. 1, all men, age 50 and older with Medicare benefits, are eligible for one digital rectal exam and one prostate-specific antigen (PSA) test each year. Congress directed the Health Care Financing Administration to cover prostate cancer screening for beneficiaries, beginning this year, in the Balanced Budget Act of 1997.

Researchers announced recently that they have developed a new system to deliver the p53 tumor suppressor gene directly into the tumor through the bloodstream. The system, when used in combination with radiotherapy and chemotherapy, may significantly improve treatment outcomes for prostate cancer patients. The findings were presented at the International Conference on Molecular Cancer Therapeutics sponsored by the American Association of Cancer Research (AACR), National Cancer Institute (NCI), and European Organization for Research and Treatment of Cancer (EORTC).

SAN ANTONIO-Increasing the radiation dose from 70 Gy to 78 Gy favorably affects outcome in some patients with locally confined prostate cancer, according to preliminary results of a randomized dose escalation study reported at the 41st Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO).

Testing further for a form of prostate-specific antigen (PSA) can help urologists find, stage, and classify prostate cancer in men whose PSA tests are ambiguous, according to a multicenter study that included The Johns Hopkins Hospital. The additional test, which is routinely available for all men taking the PSA test, can also help patients and their doctors determine the best course of treatment. The test measures free PSA, the form of PSA not bound to proteins in the blood. According to the study, the higher the percentage of free PSA compared to the bound form, the smaller the tumor is likely to be, the less chance there is that it has spread from the prostate, and the less likely it is that the disease is the most aggressive form.

SAN ANTONIO -The Southwest Oncology Group (SWOG) has announced the start of the first major phase III trial to compare the chemotherapy combination of docetaxel (Taxotere) and estramustine phosphate (Emcyt) with the commonly used combination of mitoxantrone (Novantrone) and prednisone for the treatment of advanced, hormone-refractory prostate cancer.

The Southwest Oncology Group (SWOG) announced the beginning of the first major phase III clinical trial comparing the combination of docetaxel (Taxotere) and estramustine (Emcyt) to the commonly used combination of mitoxantrone (Novantrone) and prednisone in the treatment of advanced, hormone-refractory prostate cancer. Patient enrollment is currently underway, with approximately 660 men being recruited. This trial is being conducted by SWOG and is funded by the National Cancer Institute (NCI) in collaboration with the Cancer and Leukemia Group B (CALGB) and North Central Cancer Treatment Group (NCCTG).

BALTIMORE-Physicians should consider using intravesical chemotherapy or immunotherapy as adjuvant therapy following surgery for non-muscle-invasive bladder cancer, according to new treatment guidelines released by the American Urological Association (AUA). “The fact that the peer-reviewed published data show that the use of intravesical agents after surgery lowers the probability of recurrence but not progression is the most important finding that we made,” panel chair Joseph A. Smith, Jr., MD, of the Vanderbilt University Medical Center, said in a news release.

The management of patients with clinical stage I nonseminomatous germ-cell tumors is still highly controversial. In a recent survey, urologists and oncologists were asked to state their choice of treatment for patients with clinical stage I nonseminomas who were at high risk for recurrence after orchiectomy. Not surprisingly, urologists chose retroperitoneal lymph node dissection over chemotherapy, while oncologists indicated a preference for adjuvant chemotherapy.[1]
