MCL develops from malignant B cells within the lymph node2-5

  • Originates in the mantle zone of lymphoid follicles3,5
  • MCL cells characteristically exhibit chromosomal translocation t(11;14) (q13;q32) and overexpression of cyclin D1 in addition to expression of the CD19 and CD20 antigens4,6,7
    • Cyclin D1 disrupts the cell cycle, which results in MCL oncogenesis4

MCL cells are often located in the peripheral blood, bone marrow, spleen, and gastrointestinal tract8

Mantle cell lymphoma patient demographics and symptoms. Mantle cell lymphoma patient demographics and symptoms.

Patient demographics9,10

  • Median age is 69
  • ~3x more common in males
  • Non-Hispanic, White

Most patients present with generalized lymphadenopathy; additional signs and symptoms of MCL include11-15:

  • Unexplained weight loss
  • Drenching night sweats
  • Fever
  • Fatigue
  • Lymphocytosis
  • Pain
  • Hepatosplenomegaly
  • GI symptoms
  • Skin rash

Pathological tests used for MCL diagnosis and risk assessment1

IHC stains and flow cytometry.

IHC stains and flow cytometry

  • Cyclin D1
  • Ki-67 proliferation index
  • CD19
  • CD20
  • CD5
  • CD23
Genetic testing/chromosomal evaluation.

Genetic testing/chromosomal evaluation

  • TP53
  • IGHV status
  • FISH test for t(11;14)
microscope icon.

Diagnostic testing

  • PET and CT scans
  • Bone marrow biopsy
  • CBC, blood chemistry, and LDH
colonoscopy and upper GI endoscopy.

Other testing

  • Colonoscopy
  • Upper GI endoscopy

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for B-Cell Lymphomas recommend including TP53 sequencing and Ki-67 immunohistochemistry as an essential component of diagnostic testing for MCL1

CD20, CD3, CD5, cyclin D1, CD10, CD21, CD23, BCL2, BCL6, and SOX11 are also recommended as essential components of the diagnostic immunohistochemistry panel1

MCL characteristics associated with high-risk for aggressive disease5,16

  • Presence of the TP53 mutation
  • Ki-67 index ≥30%
  • Blastoid/pleomorphic MCL
  • Complex karyotype
  • Presence of B symptoms
  • Elevated LDH
  • High-risk MIPI score

MCL progression within 2 years of diagnosis or treatment failure may identify a high-risk population17,18
