Cancer Category/Type

Cancer Sub-Classification / Subtype

  • Gamma Heavy Chain Disease (gHCD)

Definition / Description of Disease

  • gHCD is a B-cell neoplasm of lymphocytes, plasmacytoid lymphocytes and plasma cells[1][2]
  • Heterogenous clinical and pathological presentation[1]
  • Disseminated lymphoproliferative disorder is present in most patients at diagnosis[1][2][3]
  • It produces truncated monoclonal gamma (g) immunoglobulin (IgG) heavy chain that is incapable of associating with light chains[2]
  • Have concomitant autoimmune disease (mostly rheumatoid arthritis)
  • Three clusters of γ-HCD patients are identified:
    1. In around 60% of cases, γ-HCD is associated to disseminated lymphoma and patients typically have poor condition.
    2. In 25% of patients, γ-HCD is associated to localized lymphoma, affecting bone marrow, skin, thyroid, parotid, gastrointestinal or oropharynx tract (MALT lymphoma)
    3. In 15% of patients, γ-HCD is associated with autoimmune disease, mainly RA[4]

Synonyms / Terminology

  • Franklin disease[5]/ γHCD

Epidemiology / Prevalence

  • Incidence: Very rare, till date, ~only 200 cases have been reported in the literature[6]
  • Median age: 68 years (range, 42–87 years)[7]
  • Slight female predominance[3]

Clinical Features[3]

Signs & Symptoms

  • Anorexia
  • Fever
  • Weakness
  • Weight loss
  • Recurrent bacterial infections
  • Concomitant autoimmune disorder
    • Rheumatoid arthritis
    • Myasthenia Gravis
    • Autoimmune cytopenia
    • Systemic Lupus Erythematosus
    • Thyroiditis
    • Vasculitis
    • Wasting
    • Sjögren syndrome
    • Thrombocytopenia
    • Autoimmune hemolytic anemia

Laboratory Findings

  • Anemia
  • Thrombocytopenia

Molecular Biology and Genetics

  • gHCD seems to be caused by deletions and/or insertions within the rearranged variable region genes (V), which could be a by-product of somatic hypermutation[2][8]

Sites of Involvement

  • Bone marrow
  • Peripheral blood
  • Spleen
  • Liver
  • Lymph nodes
  • Waldeyer ring
  • Gastrointestinal tract
  • Extranodal sites

Morphologic Features[6]

  • Mixed proliferation of various cell types:
    • Lymphocytes
    • Plasmacytoid lymphocytes
    • Plasma cells
    • Scattered immunoblasts
    • Reed–Sternberg cells
    • Eosinophils and histiocytes
  • Vascular proliferation may give rise to the histologic differential diagnosis of Hodgkin’s lymphoma or certain forms of T-cell lymphoma

Immunophenotype[6]

Finding Marker
Positive (B-cell lineage marker) CD19, CD20, CD79a, IgG (cytoplasmic) without light chain
Positive-Plasmacytoid cells MUM1/IRF4
Positive-Plasma cells CD38, CD138
Negative CD5, CD10

Chromosomal Rearrangements (Gene Fusions)

  • No consistent gene fusions[9]

Characteristic Chromosomal Aberrations / Patterns

  • No consistent pattern reported

Genomic Gain/Loss/LOH[2][8]

  • No consistent chromosomal gains or losses reported.
  • A single case report of trisomy of chromosome 7[10]

Gene Mutations (SN V/INDEL)

  • g-HCD lacks MYD88 L265p mutation associated with lymphoplasmacytic lymphoma, hence gHCD should no longer be considered a variant of LPL[11]
  • Deletions and insertions account for approximately 6% of somatic point mutations introduced into rearranged VH region genes of germinal B cells[12].
  • No sequencing data is available till date.

Epigenomics (Methylation)

  • No recurrent epigenomic alterations have been reported.

Genes and Main Pathways Involved

  • N/A

Diagnostic Testing Methods[13][14][15]

  • Immunofixation (IF) is must and gold standard
  • Serum Protein Electrophoresis (SPEP)
  • Urine Electrophoresis
  • Morphology and immunophenotyping
  • MALDI-TOF MS could greatly improve the recognition of HCD because it directly detects the light chains and heavy chains and provides structural information about the proteins.

Clinical Significance (Diagnosis, Prognosis and Therapeutic Implications)[16]

  • N/A

Familial Forms

  • None reported

Other Information[16]

Some cases of gamma-HCD (γ-HCD) are concurrent with other lymphoid neoplasm have been reported in the literature and are listed below; treatment option varies with concurrent neoplasm

  • None
