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%
extranodal)
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
