news feature© 2010 Nature America, Inc. All rights reserved.The HER2 testing conundrumProblems in interpreting diagnostic tests for HER2 may becompromising patient access to effective treatments. As newversions of therapies targeting HER2 work their way throughclinical trials, will the situation get even murkier? Malorye Allisoninvestigates.A recent study from the University of California,San Francisco, reveals that one in five HER2tests gives the wrong answer 1 . Furthermore, thearticle, which reviews the medical literature,reports that as many as two-thirds of breastcancer patients who should be tested for HER2are not, and consequently a significant fractionof women treated with Genentech’s Herceptin(trastuzumab) have never been tested for HER2overexpression.The health benefit provider Wellpoint,of Indianapolis, might dispute that finding.According to Genentech staff scientist MarkSliwkowski, the insurer has data showing that98% of its breast cancer patients are tested.However, doctors differ in their views on testingbefore prescribing Herceptin. “Some doctorsdon’t know how to interpret test results,Table 1 Selected HER2 testsCompanyLocationBiogenexSan Ramon, CaliforniaDakoGlostrup, DenmarkDakoGenomic HealthInvitrogenCarlsbad, CaliforniaMonogram BiosciencesSiemens Healthcare DiagnosticsErlangen, GermanyVentana-RocheTucsonVentana-RocheVysis (Abbott)Name of testStatusInSite HER2/neu CB11FDA approvedHER2 FISH pharmDx KitFDA approvedHercepTestFDA approvedOncotype DXCLIA validatedSPOT-Light HER2 CISH KitFDA approvedHERmark Breast Cancer AssayCLIA-validatedHER2/neu ELISAFDA approvedthey prefer just to prescribe it and assess thepatient’s progress,” says Michael Liebman ofthe patient stratification company StrategicMedicine of Kennett Square, Pennsylvania.More than a decade after the drug receivedUS Food and Drug Administration (FDA)approval, the personalized medicine paradigmclearly has holes. Many experts are frustratedand troubled by the state of HER2 testing, especiallyas new opportunities for tests are on thehorizon. And as trials testing Herceptin at earlierstages and in combination with other drugscontinue, experts are starting to wonder whatbesides HER2 overexpression might be influencingan individual’s response to the drug.These questions promise to not only spur thedevelopment of a range of new tests to guidebreast cancer therapy but also fundamentallyInform HER2 Silver in situ HybridizationApproved in Europe and elsewhere but notby FDAPathway anti-HER2/neu (Clone CB11)FDA approvedPathVysion HER2 DNA Probe KitFDA approvedCLIA, Clinical Laboratory Improvement Amendment; ELISA, enzyme-linked immunosorbent assay.change understanding of this disease, lead tonew treatments and potentially have an impacton treatment of other cancers.Testing tempestPersonalized medicine proponents point toHerceptin as a paradigm changer: the monoclonalantibody targeting HER2 (also referredto as HER2/neu and ERBB2) evens the playingfield for breast cancer patients overexpressingHER2, whose tumors are typically more aggressive.But testing was problematic from thestart, due to either sloppy execution or complextumor biology. “Giving Herceptin earlyimproves outcome so dramatically that it is anabsolute tragedy to miss patients who shouldbe getting it,” says Jeffrey Ross, from AlbanyMedical College in Albany, New York, whohelped develop a fluorescent in situ hybridization(FISH) HER2 test marketed by DownersGrove, Illinois–based Vysis (Table 1). FISH testsare currently considered the gold standard.As more data become available and theHER2 story evolves, it’s becoming clear thatsome pieces don’t fit together quite as wellas they might.
