B-CELL NEOPLASMS

(PRECURSOR AND MATURE)

CANCER RESEARCH CENTER, UNIVERSITY & UNIVERSITY HOSPITAL of SALAMANCA (SPAIN)

Multicolor Immunophenotyping: Standardization and Applications

March 9-11, 2012 TMH, Mumbay (India)


DIAGNOSTICS IN HEMATO-ONCOLOGY

1. Making the diagnosis

Normal  reactive/regenerating  malignant

Annually > 300,000 new patients with a hematological malignancy in developed countries

2. Classification of hematopoietic malignancies

- relation with prognosis

- relevance of risk-group definition in treatment protocols

Based on differentiation characteristics and particularly on chromosome aberrations, resulting in fusion gene transcripts or aberrantly (over) expressed genes

3. Evaluation of treatment effectiveness

Detection of minimal residual disease (MRD):

MRD-based risk-group stratification (treatment reduction or treatment intensification)

Annually > 400,000 follow-up samples in leukemia patients (ALL, AML, CML)

Prepared by JJM van Dongen

Results concerning bcr abl ruo kit
Results concerning BCR-ABL RUO kit proteins

Weerkamp et al, Leukemia, 2009

  • High specificity of BCR-ABL RUO High concordance (100%; 145/145) between BCR-ABL PCR results and the BCR-ABL RUO results; Results: - 17/78 precursor-B-ALL were BCR-ABL positive in both assays (mainly adults) - 19/19 CML were BCR-ABL positive in both assays (with borderline positivity in one CML case; MFI of 144) - 0/48 of other (acute) leukemias were BCR-ABL positive

  • Mean Fluorescence Intensity (MFI) values two main groups of positive patient samples were seen: ● high level positivity: MFI values ≥ 1,000 ● lower level positivity: MFI values ≥ 135, but < 1,000 negative samples were defined as MFI values < 135

  • Different MFI values in precursor-B-ALL and CMLPrecursor-B-ALL: 88% (15/17) high level positivityCML: 84% (16/19) low level positivity (true low expressionor remaining protease activity?)

Final statement about the bcr abl ruo testing
Final Statement about the BCR-ABL RUO testing proteins

  • The main advantages of the immunobead assay are:

  • Not dependent of the breakpoint position in the fusion gene;

  • No need for special laboratory facilities other then a routine flow cytometer;

  • Providing results within several hours;

  • The possibility to run in parallel to routine immunophenotyping: no extra technician time needed !!;

  • Allowing multiplexing with differently-labeled beads, that can detect different fusion proteins within the same disease category

Panel construction – characterization markers LEUKAEMIAS

  • Tested markers (n=66):

    • Backbone markers (e.g. CD19, CD20, CD22, CD37, CD45).

    • Lineage assignment and maturation stage (e.g. Bcl-2, HLA-DR, IgM, CD10,CD43, CD24, CD27, CD38, CD39, CD63, CD81, CD95, CD138).

    • Disease specific (e.g. CD5, CD23, CD25, CD79b, CD103, CD200).

    • Integrins and chemokine receptors (e.g. CD11a, CD11c, CD31, CD49d CD62L, CXCR5, LAIR1).

  • 150 cases of B-Lymphoproliferative disorders tested; aim:

    • Improve differential classification of B-NHL

    • Avoid markers with redundant information

  • FINAL: 4 tube 8-color panel (20 antibodies)

UTILITY OF THE NEW SOFTWARE TOOLS LEUKAEMIAS

Standardization of FCM immunophenotyping

  • How to get optimal and comparable measurements?

  • Which are the most appropriate fluorochromes?

  • What is the optimal sample preparation protocol?
