Clinical Overview

Key Points

Double- and Triple-Hit Lymphomas

B-cell lymphomas with 2 or 3 recurrent chromosomal breakpoint aberrations (rare) are referred to as double- or triple-hit lymphomas. These usually involve the MYC oncogene in association with the BCL2 and/or BCL6 gene rearrangements. These are classified by WHO as a “high-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements” (Swerdlow, WHO, 2016).

It is important to identify these high-grade lymphomas as they tend to manifest aggressive behavior and respond poorly to traditional chemotherapy.

Prognosis

International Prognostic Index scoring system
- Based on pretreatment clinical factors of age (≤60 years); Ann Arbor tumor stage (I or II); number of extranodal sites (≤1); Eastern Cooperative Oncology Group (ECOG) performance status (0 or 1); and serum LD (≤1 times normal) – all scored as 0
- Patients placed in four risk groups
- Limited usefulness in follicular lymphoma, mantle cell lymphoma, NK lymphoma, nasal-type lymphoma, hepatosplenic lymphoma, and enteropathy-type lymphoma
Follicular Lymphoma International Prognostic Index scoring system
- Five risk factors (each scored as one point)
  - Blood hemoglobin <12 g/dL
  - Serum LD >normal
  - Ann Arbor tumor stage (III or IV)
  - >4 nodal sites
  - Age >60 years
- 0-1 risk factor – low risk (5-year survival 90%)
- 2 risk factors – intermediate risk (5-year survival 78%)
- 3 risk factors – high risk (5-year survival 53%)
All prognostic indices may change in the future as the IPI and FLIPI indices were developed before immunotherapy
Genetic mutations (cytogenetics)
- Follicular lymphoma
  - Adverse prognosis associated with del 17p, trisomy 12 and abnormalities of 6p
- Diffuse large B-cell lymphoma (DLBCL)
  - Better prognosis associated with t(14;18)
  - Adverse prognosis with MYC oncogene; BCL2 gene, p53(+)
- Follicular and DLBCL
  - Dismal outcomes for 8q24/MYC in association with 18q21/BCL2 or 3q27/BCL6
- Double-hit and triple-hit lymphomas
  - Refer to Key Points for double- and triple-hit lymphomas
