Comparing Radical Prostatectomy and Brachytherapy for Localized Prostate Cancer
September 1st 2004There are two problems with thepaper by Quaranta et al, neitherof which can be overcomewith discussion or sophistry. The firstconcerns the criteria used to determinewhether a report would be includedin this analysis. Specifically,any series with a median follow-up ofonly 3 years was included if it alsomet the other inclusion criteria. Thisis simply inadequate, as there is greatconsensus that studies with 3-year follow-up miss many recurrences. Thesecond problem with the paper is thedefinition of recurrence. The AmericanSociety for Therapeutic Radiologyand Oncology (ASTRO) criteriaused by the authors has proven inferiorto using a cutoff of 0.2 ng/mL forprostate-specific antigen (PSA) nadirfollowing brachytherapy. The inaccuracyin using ASTRO criteria fordetermining cure by brachytherapy isparticularly pronounced in series withshort follow-up such as the 3-yearmedian follow-up criterion used inthis paper.
Understanding the Pathobiology of Chemotherapy-Induced Nausea and Vomiting
September 1st 2004Improved understanding of the physiologic and neuropharmacologicmechanisms underlying chemotherapy-induced nausea andvomiting (CINV) has driven significant progress in the treatment ofCINV over the past 2 decades. Recognition of the role of neurotransmittersand their receptors in the process of CINV has been central tothis progress. Initial attention focused on dopamine, then on serotonin,and most recently on substance P, which has yielded a usefulnew class of antiemetic medications known as selective neurokinin-1receptor antagonists. Preclinical studies of these neurokinin-1 receptorantagonists suggested that they would demonstrate broad antiemeticactivity in acute emesis, demonstrate activity against cisplatininduceddelayed emesis, be well tolerated, and contribute to enhancedefficacy when used in combination with other classes of antiemetics.These suggestions appear to have been largely borne out in clinicaltrials. Pharmacogenomics may offer a means to further extend andapply our understanding of CINV by enabling more selective targetingof antiemetic therapies. To date, the application of pharmacogenomicsto CINV has focused on variations in the metabolism of serotoninreceptor antagonists by CYP 450 genotype and variations in the5-HT3 receptor gene itself.

Comparing Radical Prostatectomy and Brachytherapy for Localized Prostate Cancer
September 1st 2004Radical prostatectomy and ultrasound-guided transperinealbrachytherapy are both acceptedtreatment options for men with clinicallylocalized prostate cancer.Investigators continue to argue overthe relative effectiveness of each ofthese procedures, not only from thestandpoint of cure, but also with regardto how each treatment affectsquality of life. With the recent closureof a prospective, randomized trial addressingthese issues (the SurgicalProstatectomy Interstitial RadiationIntervention Trial, or SPIRIT) due tolack of patient accrual, it is unlikelythat a direct comparison of these techniqueswill be performed in the foreseeablefuture.

Comparing Radical Prostatectomy and Brachytherapy for Localized Prostate Cancer
September 1st 2004Radical prostatectomy and ultrasound-guided transperinealbrachytherapy are both commonly used for the treatment of localizedprostate cancer. No randomized trials are available to compare thesemodalities. Therefore, the physician must rely on institutional reportsof results to determine which therapy is most effective. While some investigatorshave concluded that both therapies are effective, others haveconcluded that radical prostatectomy should remain the gold standardfor the treatment of this disease. This article reviews the major seriesavailable for both treatments and discusses the major controversiesinvolved in making these comparisons. The data indicate that for lowriskdisease, both treatments are effective, controlling disease in over80% of the cases, with no evidence to support the use of one treatmentover the other. Similarly, for intermediate-risk disease, the conclusionthat one treatment is superior to the other cannot be drawn. Brachytherapyshould be performed in conjunction with external-beam radiationtherapy in this group of patients. For patients with high-risk disease,neither treatment consistently achieves biochemical control rates above50%. Although radical prostatectomy and/or brachytherapy may playa role in the care of high-risk patients in the future, external-beamradiation therapy in combination with androgen deprivation has thebest track record to date.

Commentary (Mulcahy/Benson)-Gallbladder and Biliary Tract Carcinoma: A Comprehensive Update
July 1st 2004Cancers of the gallbladder andbile ducts are uncommon, aggressivemalignancies thatpresent both a diagnostic and therapeuticchallenge. With an annual incidenceof 7,200 cases in the UnitedStates, and the difficulty in diagnosingbiliary tract tumors, there is a paucityof data supporting therapeuticoptions. This comprehensive updateby Daines et al demonstrates the advancesin diagnostic and staging techniques,which have led to appropriatesurgical resection. Despite these advances,the prognosis of gallbladderand cholangiocarcinoma remains bleak,without significant improvement in survival,contrary to the author's optimisticintroduction. There is a lack of activechemotherapy and clinical trials exploringadjuvant and palliative therapy.Guidelines such as those advocated bythe National Comprehensive CancerNetwork (NCCN) help to establish standardsfor the evaluation and treatmentof these uncommon tumors and providea framework for the developmentof clinical trials.[1]
