Agent shows superior safety as first-line RCC therapy
September 1st 2006Atlanta-Sorafenib tosylate (Nexavar), a newer oral multi-kinase inhibitor that targets tumor growth and vascularization, was generally well tolerated by patients with metastatic clear-cell renal cell carcinoma in a randomized phase II trial that compared the efficacy and tolerability of the drug with that of interferon in first-line therapy. Study results were presented by Bernard Escudier, MD, head of the immunotherapy and innovative therapy unit at Institut Gustave Roussy Villejuif, Cedex, France, at the American Society of Clinical Oncology annual meeting here.
Monoclonal antibody cited for activity against RCC
September 1st 2006Atlanta-Contrary to earlier data from a single-arm study, the addition of erlotinib (Tarceva) to the monoclonal antibody bevacizumab (Avastin) does not significantly delay disease progression in patients with metastatic renal cell carcinoma, according to data presented at the American Society of Clinical Oncology annual meeting. The new findings suggest that bevacizumab is responsible for increasing progression-free survival in this patient population.
Two CT scans needed to follow nonseminomatous tumors
September 1st 2006Atlanta-Sixty percent of testicular germ cell tumors, such as embryonal cell carcinoma, teratocarcinoma, and teratoma, are nonseminomatous. Stage I nonseminoma patients are usually of young age, the cure rate is high, and most patients have many decades of life ahead after orchidectomy, followed by surveillance. Therefore, long-term investigations of morbidity and treatment are of significant concern.
Chemo-stem cell combo is effective in salvage therapy
September 1st 2006Atlanta-Patients with refractory metastatic testicular cancer who have not responded to their initial chemotherapy may respond to high-dose chemotherapy given in tandem with blood stem cell transplant, according to a study presented at the American Society of Clinical Oncology annual meeting here.
Chemo appears superior to RPLND in stage I testis cancer
September 1st 2006Atlanta-Will patients with stage I nonseminomatous testicular cancer (NSGCT) do better with one course of chemotherapy than with retroperitoneal lymph node dissection (RPLND)? That's what the results of a large, long-term German study implied, but some have sounded a note of caution, wanting longer and better follow-up before recommending any first-line therapy other than rigorous surveillance. The answer may depend on the care that will work best in the community, rather than on the care available at specialized centers.
Testosterone levels do not affect ED
September 1st 2006Atlanta-A cross-sectional analysis of data from the Massachusetts Male Aging Study indicates that there is no relationship between testosterone levels and erectile dysfunction, while elevated levels of luteinizing hormone were associated with a higher prevalence of ED.
Shock waves may improve Peyronie's pain, deviation
September 1st 2006Atlanta-Using extracorporeal shockwave therapy (ESWT) to reduce pain and to correct some deviation in Peyronie's disease is a relatively new concept whose application appears to be more extensive in Europe than in the United States. The majority of European studies on this topic involve small cohorts of 30 or fewer patients, and although several have included control groups who did not undergo treatment, none of these trials included sham treatment to define the strength of the placebo effect.
1-year survival predicts response to BCG therapy
September 1st 2006Atlanta-Up to half of all bladder cancer patients receiving Bacillus Calmette-Gu?rin (BCG [TheraCys, TICE BCG]) therapy will fail to respond or relapse within 5 years, but those who make it through the first year have a better chance at responding to subsequent therapy than those who fail sooner. The response rate of those who fail after a year is similar to the response rate of patients who have yet to receive their first treatment, according to a University of Iowa study presented at the AUA annual meeting.
Restaging TUR predicts risk of bladder cancer progression
September 1st 2006Atlanta-Conducting a second transurethral resection to restage bladder cancer should be a routine practice, according to Harry Herr, MD, attending physician at Memorial Sloan-Kettering Cancer Center, New York. The results are diagnostic, therapeutic, and invaluably prognostic, he said.
Bladder cancer screening appears to save lives, money
September 1st 2006Dallas-A new study shows that screening high-risk populations for bladder cancer may save both lives and money. That conclusion stands in sharp contrast to screening programs for other cancers, which save lives but increase costs.
PDE-5 inhibitors show efficacy in ED and LUTS
September 1st 2006Atlanta-Sometimes studies are more notable for the questions they raise than for the ones they answer. Kevin T. McVary, MD, professor of urology at Northwestern University Feinberg School of Medicine, Chicago, presented a study at the AUA annual meeting showing that the phosphodiesterase type-5 inhibitor sildenafil citrate (Viagra) improves both erectile function and lower urinary tract symptoms, but has no apparent effect on flow rates.
Tandem therapies help relieve CP/CPPS symptoms
September 1st 2006Atlanta-Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has a huge impact on men's sexuality, but a combination of pelvic muscle trigger point release physiotherapy and relaxation training can go a long way toward improving sexual dysfunction in these men, said Rodney U. Anderson, MD, professor of urology, Stanford University School of Medicine, Stanford, CA.
Pollen extract improves pain in men with CP/CPPS
September 1st 2006Atlanta-Urologists can add one more alternative, plant-based medication to the list of intriguing possibilities for treating urologic disease. This one is a rye-pollen extract called Cernilton that showed promising results in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in a preliminary, placebo-controlled study from Germany.
Refined bisphosphonate schedule may offer benefit
September 1st 2006Atlanta-Bisphosphonates have already been shown to reduce loss of bone mineral density (BMD) in men undergoing androgen deprivation therapy and to reduce skeletal events and markers of bone turnover in men with metastatic prostate cancer. However, the drugs carry risks and can be expensive. That's why Dror Michaelson, MD, PhD, an assistant in medicine at Massachusetts General Hospital and instructor at Harvard Medical School, Boston, examined the effects of zoledronic acid (Zometa) in a once-annual dosing schedule that is much reduced compared with that used in past trials.
Quality of life improves with 21-day docetaxel regimen
September 1st 2006Atlanta-Based on the landmark TAX-327 study, which showed a survival benefit of treatment every 3 weeks with docetaxel (Taxotere)/prednisone over mitoxantrone hydrochloride/prednisone, the every-3-weeks docetaxel regimen has now become a standard of care for men with metastatic hormone-refractory prostate cancer.
COX-2 inhibitor exhibits anti-cancer effects in prostate cancer
September 1st 2006Atlanta-Initial results with neoadjuvant celecoxib (Celebrex) strongly suggest that this may be a promising agent in the management of patients with early localized prostate cancer, British researchers reported at the American Society of Clinical Oncology annual meeting.
Neoadjuvant chemo is well tolerated in high-risk PCa
September 1st 2006Atlanta-Neoadjuvant docetaxel added to androgen suppression therapy and radiation therapy appears to be safe and active in patients with high-risk localized prostate cancer, according to findings of a new phase II study from Canada reported here at the American Society of Clinical Oncology annual meeting.
PSADT value limited in predicting cancer outcome
September 1st 2006Atlanta-PSA doubling time (PSADT) appears to have limitations as a predictor of treatment outcome, according to results of a phase II, placebo-controlled trial of atrasentan (Xinlay) in patients with early-stage, hormone-naive prostate cancer. Researchers found that both placebo and drug recipients showed an extended PSADT of similar length.
RALP may offer improved margins, ease of transition
September 1st 2006Atlanta-Positive surgical margin rates decrease as experience with robot-assisted laparoscopic prostatectomy (RALP) increases. In addition, formal laparoscopic training may not be necessary for optimizing some outcomes with the robotic procedure, according to the findings of two new studies presented here at the AUA annual meeting.
Links probed between prostate volume, cancer prediction
September 1st 2006Atlanta-Results from the Prostate Cancer Prevention Trial (PCPT) showing treatment with the type 2-specific 5-alpha-reductase inhibitor finasteride (Proscar) reduced the incidence of prostate cancer, but was associated with increased detection of high-grade cancers has prompted additional research on the association among prostate cancer detection, cancer grade, and prostate volume.
