Operative delay predicts cancer return after cystectomy
October 1st 2003Montreal, Quebec-The interval between transurethral resection of bladdertumor and radical cystectomy significantly influences 3-year disease recurrencerates in patients with transitional cell carcinoma of the bladder, saidresearchers from McGill University in Montreal.
Platinum-based chemo shows modest benefit in bladder Ca
October 1st 2003Chicago-Neoadjuvant platinum-based chemotherapy is associatedwith a statistically significant improvement in the overall survival ofpatients with locally advanced bladder cancer, according to the resultsof a recent meta-analysis presented at the AUA annual meeting here. However,the treatment benefit is not strong enough to support a recommendation forusing neoadjuvant chemotherapy in this setting, said Amir Sherif, MD, PhD,speaking on behalf of the Nordic Cooperative Bladder Cancer Group.
Model predicts benefit of RP over watchful waiting
October 1st 2003Albuquerque, NM-A new outcome model of prostate cancer progression followingradical prostatectomy has demonstrated good correlation between the model'spredictions and actual patient data. A study using this model suggests thatmen benefit more from radical prostatectomy over watchful waiting, evenif residual disease remains after surgery.
Lithotriptors show no significant outcome differences
October 1st 2003Edinburgh, Scotland-When used by the same operators in a single center, shockwave lithotriptors of different power generators provide comparable results and have similar complication rates in the treatment of renal stones, urologists at a Scottish stone center reported at the AUA annual meeting.
Enzyme inhibitors may help in cancer therapy following initial procedures
September 25th 2003Certain enzyme inhibitors may slow tumor formation within weeks and could lead to treatments that retard or prevent recurrences of cancers, researchers at UT Southwestern Medical Center at Dallas have discovered.
Disease-causing genetic mutations in sperm increase with age
September 25th 2003Older men's sperm is more likely to contain disease-causing genetic mutations, suggests an analysis of sperm from men of various ages by scientists from the McKusick-Nathans Institute for Genetic Medicine at Johns Hopkins University, Baltimore.
AMA applauds Texas medical liability victory
September 25th 2003Texas patients and physicians scored a major victory when voters approved Proposition 12, a constitutional amendment that authorizes the legislature to determine limitations on non-economic damages in medical liability cases. The vote ratifies the state's recently enacted medical liability reforms.
Surgical mishaps more common in physician offices than ASCs
September 25th 2003Patients undergoing surgery in ambulatory surgery centers are safer than those who undergo procedures in doctors' offices, although the relative risk of death or injury is low in both types of facilities, a new Florida study indicates.
Prostate cancer deaths on the decline nationwide
September 10th 2003Progress has been shown in the death rates from prostate cancer and the other three leading cancers-lung, breast, and colorectal. Deaths from prostate cancer have fallen 4.0% during the 5-year period from 1996 to 2000. Bladder cancer decreased by 0.4% over the same period.
Combination treatment boosts bladder cancer survival rate
September 10th 2003Patients with locally advanced bladder cancer have more than a fighting chance for survival with neoadjuvant chemotherapy, which has been found to provide a longer life in patients compared with the standard treatment of surgery alone, according to an 11-year study published in the New England Journal of Medicine (2003; 349:859-66).
SNPing Away at Prostate Cancer: Susceptibility and Pharmacogenetics
September 1st 2003Increasing knowledge of the ways in which we differ from each other genetically has the potential to change the way medicine is practiced in the not too distant future.88 One of the most common forms of human genetic diversity is the single nucleotide polymorphism (SNP), a single base-pair position in genomic DNA at which different sequence alternatives (alleles) exist in normal individuals.
Molecular Mechanisms in Prostatic Carcinogenesis
September 1st 2003In the developed world, environmental factors-particularly diet-seem to play a prominent role in the development of prostate cancer.27 Research into the molecular pathogenesis of prostate cancer may help us assess why prostate cells are particularly vulnerable to such environmental effects and to determine what somatic genome mutations are involved in the transformation of normal epithelium into intraepithelial neoplasia (PIN) and ultimately to invasive carcinoma (Figure 5).
Perspectives in Prostate Chemoprevention
September 1st 2003Chemoprevention is the use of natural or synthetic agents to avert the induction of, or to inhibit, delay, or suppress the progression of cancers or other diseases. Carcinogenesis is a process that occurs over a period of months to years and is under the influence of a range of genetic and environmental factors.
How drug therapy is changing the face of urology practice
September 1st 2003Urology has always been a fascinating and somewhat hybrid specialty inthe field of medicine. First and foremost, it has been a surgical specialty,requiring many years of intense surgical training to master. Many of ushave been drawn to urology because of the wide assortment of surgical proceduresand the ability to put to use the highest technological advancements inthe course of our work.
