Based othe SS, the medasurvval of patents wth stage , , or dsease s estmated at 62, 44, and 29 months, respectvely.6 Despite the fact that serum two mcroglobuland albumlevels combne the SS to provde a strong prognostc device, quite a few ndependent prognostc markershave beedescrbed that may even more assst predctng final result.17 A lot of establshed prognostc markers allowng dentfcatoofhgh rsk patents early the dsease coursehave beederved from studes of conventonal chemotherapy and nclude age, two mcroglobullevel, Worldhealth Organzatoperformance standing, serum calcum, nterleuk6 degree, bone marrow plasma cell labelng ndex, and morphologcal options.18,19however, the present era ofhgh dose chemotherapy, novel mmunomodu latory agents, and new smaller molecule nhbtors, a variety of other prognostc markers relatng to mechansms of dsease progressoare now consdered to become mportant.
17 Abnormal cytogenetcs play a domnant position predctng the outcome of patents wth acute leukema, and also the read the article evdence now suggests that cytogenetcshave a smar part MM.Trcot and colleagues20,21 observed, usng regular cytogenetc technques, that patents wth newly dagnosed or prev ously handled dsease, the presence of partal or total dele a lot of chromosome 13 and 11q abnormaltes have been assocated wth nferor occasion absolutely free survval and OS.addton, they noted a sgnfcant assocatobetweethe unfavorable karyotypes and mmunoglobulA sotype, elevated amounts of two mcroglobuln, and age 60ears.20 Conventonal cytogenetc analyss shampered by lower mtotc actvty of myeloma cells and may mss utohalf of chromosome 13 abnormaltes.
Usng FSH, Facoand colleagues22 demonstrated that MM patents recevng selleck chemical frst lnehgh dose chemotherapy, the presence of chromosome 13 abnormaltes was strongly predctve of poor survval, especally wheassocated wth a 2 mcroglobullevel of 2.5 mg L.FSHhas snce beeused to dentfy patents wth bad, ntermedate, and better prognoss accordng to mmunoglobulheavy chatranslocatons and chromosome 13 abnormaltes wth other abnormaltes like and del17q, emergng as prognostcally unfavorable.23however, as combnatons of ndependent prognostc aspects provde higher energy thaany one particular prognostc aspect alone, the technque wth potentally thehghest utty the long term s gene expressoprofng, whch allows the smultaneous characterzatoof several dfferent cytogenetc markers.24 Evaluatoof response Evaluatoof tumor response to treatmenbased othe assessment of changes serum and or urnary M protelevel.
