B-cell lymphoma

Background

❑ B and T-cell neoplasms are clonal tumours of mature B/T/NK cells at

various stages of differentiation

❑ Highly heterogeneous : clinical features, morphology, immunophenotype

and genetics (WHO classification)

❑ Incidence: 3-15 cases/100.000 hab/year.

❑ Pathogenesis : predisposing factors

❖ primary immunodeficiency: ataxia-telangiectasia, Wiskott-Aldrich

❖ adquired immunodeficiency: : AIDS

❖ Autoimmune diseases: SEL, Sjögren

❖ Virus: Burkitt (Epstein-Barr), HTLV-1(Leucemia/linfoma), VHC, HHV-8,

HIV

❖ bacteria: gastric MALT lymphoma helycobacter p, cutaneous MALT

lymphoma- borrelia

Diagnosis

Staging

• Patient evaluation: clinical history (fever, sweats, weight loss, others,), physical

examination (LN, Waldeyer ring, size of the liver, spleen, testes and skin)

• Excisional biopsy (lymph node or others) with a detailed study of morphology,

immunophenotype and genetic studies

• Blood test: blood count, blood film chemistry (LDH, 2microglobulina, uric acid),

ESR, electrophoresis

• Serology: B-hepatitis, C-hepatitis, HIV

• PET/CT scan of the neck, chest and abdomen: to detect occult nodal and

extranodal disease

• Bone marrow biopsy: detect lymphoma invasión (only in NHL)

• Lumbar puncture: burkitt lymphoma, DLBCL, lymphoblastic lymphoma

• Other: endoscopy and endoscopic ultrasound for MALT and other

GI, magnetic resonance for primary CNS lymphoma

oMost frequent type (30-35%)

oMedian age: 60-65 y

oClinical presentation (60% nodal/40%

oHistology: diffuse proliferation of

atypical, irregular, large B-cells with

nucleoli and basophilic cytoplasm

oAggressive behavior: untreated drives

to death in days/months

Diffuse large B-cell Lymphoma (DLBCL)

❑ most frequent (30% of all lymphomas)

❑Histopathology: diffuse proliferation of atypical, irregular, large B-

cells with vessicular nuclei prominent nucleoli and basophilic

cytoplasm

❑Inmunohistochemistry: pan-B cell markers: CD19 +, CD20+, CD79a +,

CD22 +, bcl-6, bcl-2, CD10 MUM-1

❑ Cytogenetics: several trasnlocations involving chromosome 3(bcl-6).

❑ Molecular studies: rearrangement of BCL-6, 30% of cases, also

BCL-2 (t(14;18)

❑ Gene expression profiling: germinal-center B-cell lymphoma (GCB)

and non-GCB, activated B-cell sybtype.

❑ IHQ algorithm (Hans): not reproducible

❑ B-cell lymphomas are highly heterogeneous diseases that reproduce the

neoplastic counterpart behaviour (WHO classification)

❑ Diagnosis is based in a good excisional biopsy to perform an accurate

morphology, immunohistoquemistry and molecular techiniques

❑ Nowadays, B-cell lymphoma treatment is based on rituximab-containing

chemotherapy schedules as Rituximab has improved disease free and

overall survival

❑ BCR signalling pathways plays a central role in CLL progression

❑ Several BCR signaling targeted therapies have been recently introduced in

clinical practice with good clinical results (DFS and OS) and manageable

toxicity

❑ In Hodgkin’s lymphoma, Check-point inhibitors are able to restore

immunesurveillance and thus, rescue a group of refractory patients

❑ NGS technology is a crucial technology both for tailoing and monitring

treatment

❑ CAR T-cell is an immunological, targeted aprrpoach which is able to cure

refractory DLBCL and lymphoastic leukemia patients
