Anthracycline vs Nonanthracycline Adjuvant Therapy for Breast Cancer
October 1st 2004The treatment of breast cancer has progressed substantially overthe past 15 years. Data from randomized adjuvant trials have shownthat the risk of disease recurrence and death is significantly reducedwhen adjuvant chemotherapy and/or hormonal therapy is added to treatment.As new strategies are incorporated, one of the continued controversiesin patient management is whether adjuvant anthracyclinesshould be the preferred treatment for all patients. Data from randomizedand translational clinical trials have become available and arehelping to elucidate the proper role of anthracyclines, as well as their acuteand long-term toxicities. In most situations, an anthracycline is currentlypreferred, but other single and combination chemotherapies arecurrently under evaluation and appear promising for use in the adjuvantsetting. Continued breast cancer research using molecular markers(such as topoisomerase II–alpha and gene clusters) as predictors oftreatment response, could help individualize decisions regardingwhether to incorporate anthracyclines into adjuvant therapy regimens.
Prostate Cancer 2004: Insights From National Disease Registries
September 1st 2004In their article, Drs. Matthew Cooperberg,Sangtae Park, and PeterCarroll summarize four nationalregistries that have studied risk migration,practice patterns, outcomepredictions, and quality-of-life outcomesin prostate cancer. Each of thesefour large registries-the Prostate CancerOutcomes Study (PCOS), the Departmentof Defense Center for ProstateDisease Research (CPDR), the Cancerof the Prostate Strategic Urologic ResearchEndeavor (CaPSURE), and theShared Equal Access Regional CancerHospital (SEARCH)-has a particularstrength that complements theothers. As more patients enroll in theseregistries, researchers will gain greaterinsight into the patterns of care andclinical and health-related quality oflife for diverse cohorts of prostate cancerpatients.
Treatment of Advanced Non–Small-Cell Lung Cancer in Special Populations
September 1st 2004Only a minority of elderly patientswith advanced non–small-cell lung cancer(NSCLC) have been offered palliativechemotherapy, as indicated by clinicalsurveys beginning in the 1980s.Lilenbaum’s thorough review of thetreatment of locally advanced and metastaticNSCLC studies in two specialpopulations (elderly and Eastern CooperativeOncology Group [ECOG]performance status [PS] 2 patients)highlights a new trend seen with theadvent of better-tolerated chemotherapyregimens.
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.
