The subcategores of nCR and very good PRhave beentegrated nto a sngle group, VGPR, wth sCR defned as CR based mostly oEBMT crtera wth the addtonal requrement to get a regular FLC rato and the absence of clonal cells bone marrow Tivantinib 905854-02-6 by mmunohstochemstry or mmunofluorescence.VGPR s defned as serum and urne M protelevels detectable by mmunofxaton, but not oelectrophoress, or a 90% reductoserum M proteplus urnary M protelevel one hundred mg per 24hours.The MWG crtera elmnate the mandatory sx week perod to confrm response and nsteadhave a notme dependent confrmatofor relapse and or dsease progresson.26 Even more modfcatons to ths as well as valdatoof critical factors, for instance the evaluation of serum FLC are antcpated.28 Aims of therapy Remedy prolongs survval MM, while remssons are nevtably followed by relapse.
