Megjegyzések:	Disseminating cells of a primary solid tumor mayrepresent the origin of metastases and relapses. We aimed atcomparing the diagnostic efficacy of multicolor flow cytometry(MFC) and morphology/immunohistochemistry (IHC) in thedetection of disseminated tumor cells in the bone marrow (BM)and body fluids of patients with solid tumors, and in pediatricneuroblastoma cases. We investigated 72 samples retrospecivelyfrom 50 patients by MFC. Morphology/IHC data were availablein 48 cases. In the first cohort, 36 samples derived from 34patients with various forms of suspected and proven solidtumors and in the second cohort, 36 samples of 16 children withsuspected and proven neuroblastoma were analyzed at diagnosisor during follow-up in a 4-color setting by MFC, and the resultswere compared with those obtained by IHC. In the group ofvarious solid tumors, we found 91% concordance between IHCand MFC, and it was 65% in the neuroblastoma group, and77% overall. Detection of disseminated tumor cells was found tobe more effective by MFC in de novo neuroblastoma samples(100% vs. 86%). The advantage of MFC was even more pronouncedwhen minimal residual disease was evaluated (efficacy,92% vs. 68%). In contrast, efficacy of IHC was 100% in thegroup of various solid tumors, whereas it was 91% for MFC.We conclude that MFC and IHC are both essential tools forexamining infiltration of BM and body fluids by disseminatingsolid tumor cells. In the case of neuroblastoma, however, minimalresidual disease detection by MFC in a hypoplastic/aplasticBM environment was more effective than IHC, as considerablymore cells could be analyzed.
