Hodgkin s disease histological subtypes l.jpg
HODGKIN’S DISEASE HISTOLOGICAL SUBTYPES

Lymphocyte predominant

Mixed cellularity

Lymphocyte depleted

Nodular sclerosis



Classical hodgkin lymphoma l.jpg
CLASSICAL HODGKIN LYMPHOMA

  • A term to cover all types of HD other than nodular LP due to shared phenotypic and genetic properties.

  • Presents in axial nodes with contiguous nodal spread. Splenic disease tends to precede bone marrow and/or liver disease.

  • Primary mesenteric nodal or extranodal disease is hardly ever seen.

  • RS-cells are variably mixed with lymphocytes, plasma cells, eosinophils, neutrophils and histiocytes.

  • CD15+ (75%), CD30+ (100%). EBV mainly in MC-HD (75%).

  • >95% of cases arise from a “crippled” B-cell precursor:

    • Infrequent expression of B-cell markers, no Ig synthesis.


Nodular lymphocyte predominant hodgkin lymphoma l.jpg
NODULAR LYMPHOCYTE PREDOMINANT HODGKIN LYMPHOMA

  • Commonly presents with stage 1A disease – often below the diaphragm.

  • The most B-cell committed form of HD:

    • Architecturally tumour arises in abnormal follicles / nodules.

    • Expression of wide range of B-cell markers including Ig.

    • Does not express markers of classical HD and is EBV –ve.

    • Transformation to DLBCL in ~7% over time.


Lymphomas other than hodgkin s disease l.jpg
LYMPHOMAS OTHER THAN HODGKIN’S DISEASE

  • Non-Hodgkin lymphomas:

    • 14% Hodgkin lymphoma

    • 80% B-cell lymphomas

    • 6% T-cell lymphomas

Proposal for an International Consensus on the Classification of Lymphomas

International Lymphoma Study Group

We came to the conclusion that the most practical approach to lymphoma categorization at this time is simply to define the diseases that we think we can recognize with available morphologic, immunologic, and genetic techniques. Thus, a lymphoma classification becomes simply a list of well-defined, “real” disease entities.

Important practical diagnostic points l.jpg
IMPORTANT PRACTICAL DIAGNOSTIC POINTS Diseases of the Haematopoietic and Lymphoid Tissues

  • Immunophenotyping for cell surface antigens is mandatory.

  • Certain entities require evidence of a marker chromosomal abnormality for a firm diagnosis:

    • Mantle cell lymphoma; t(11;14)

    • Burkitt lymphoma; CMYC translocation, t(8;14) or variants.

  • Certain entities require clonal cytogenetic or molecular evidence for diagnosis:

    • Cutaneous and nodal mycosis fungoides

    • Sézary syndrome


Slide24 l.jpg

Follicular Lymphoma Diseases of the Haematopoietic and Lymphoid Tissues

CD10, CD20, bcl-2, bcl-6 positive


Slide25 l.jpg

BURKITT LYMPHOMA Diseases of the Haematopoietic and Lymphoid Tissues

Endemic type – EBV+ associated with Falciparum Malaria

Sporadic (Western type) – EBV usually –ve

HIV – related – EBV ~30%

IGH/MYC translocation or variant with no IGH/BCL2, BCL6 or complex karyotype

CD10 positive. MIB1 100%. bcl-2, MUM1 negative


Important diagnostic points l.jpg
IMPORTANT DIAGNOSTIC POINTS Diseases of the Haematopoietic and Lymphoid Tissues

  • Certain entities require a multidisciplinary approach to establish a diagnosis e.g.:

    • Mediastinal large B-cell lymphoma

    • Cutaneous follicle centre lymphoma

    • Diffuse large B-cell lymphoma, leg-type

    • Primary effusion lymphoma

    • Post-transplant lymphoproliferative disorders

Guidance on Cancer Services – Improving Outcomes in Haematological Cancers – The Manual

Haematological cancers service guidance

Cancer service guidance supports the implementation of The NHS Cancer Plan for England,and the NHS Plan for Wales Improving Health in Wales.The service guidance programme was initiated in 1995 to follow on from the Calman and Hine Report, A Policy Framework for Commissioning Cancer Services.3 The focus of the cancer service guidance is to guide the Commissioning of services and is therefore different from clinical practice guidelines. Health services in England and Wales have organisational arrangements in place for securing improvements in cancer services and those responsible for their operation should take this guidance into account when planning, commissioning and organising services for cancer patients. The recommendations in the guidance concentrate on aspects of services that are likely to have significant impact on health outcomes. Both the anticipated benefits and the resource implications of implementing the recommendations are considered. This guidance can be used to identify gaps in local provision and to check the appropriateness of existing services.

standardized incidence / 100,000 populationAll patients with haematological cancer should be managed by

multi-disciplinary haemato-oncology teams which serve

populations of 500,000 or more.

• In order to reduce errors, every diagnosis of possible haematological malignancy should be reviewed by specialists in diagnosis of haematological malignancy. Results of tests should be integrated and interpreted by experts who work with local haemato-oncology multi-disciplinary teams (MDTs) and provide a specialised service at network level. This is most easily achieved by locating all specialist haemato-pathology diagnostic services in a single laboratory.
