Risk calculators and risk factors for Lymphoplasmacytic lymphoma medical therapy

Overview

Risk stratification determines the protocol of management used for lymphoplasmacytic lymphoma. There is no treatment for asymptomatic lymphoplasmacytic lymphoma. The mainstay of treatment for symptomatic lymphoplasmacytic lymphoma is Rituximab +/- Chemotherapy. Hyperviscosity syndrome is a medical emergency and requires prompt treatment with plasmapheresis. Drug of choice for the treatment of bing-neel syndrome is Ibrutinib with or without concurrent rituximab. Other treatment options include targeted therapy, immunotherapy and radiation therapy.

Medical Therapy

There's no cure for LPL with current therapies. Instead, the treatment goals are to control symptoms and prevent end-organ damage, while maximizing quality of life. There is no standard therapy for the treatment of LPL. While various drugs and combinations have demonstrated to have provided clinical benefit, hence, there are several different options for treating lymphoplasmacytic lymphoma depending on stage of the disease:[1]

Summary of how to approach different patients with lymphoplasmacytic lymphoma
Patient's condition/parameters How to proceed accordingly
Observation
Hperviscosity present:

Hyperviscosity absent:

  • DRC only
Consider clinical trial + stem cell transplant in selected patients:

Watchful waiting/active surveillance for asymptomatic patients with LPL

There is no treatment for asymptomatic patients with LPL. As LPL develops slowly and may not need to be treated right away, it is monitored by healthcare team every 3-6 months which is known as watchful waiting/active surveillance and treatment is started when symptoms appear, such as hyperviscosity syndrome, or there are signs that the disease is progressing more quickly.[2] Active surveillance includes monitoring of the following laboratory parameters:

Symptomatic patients with LPL

Symptomatic patients with LPL are started on chemotherapy depending on the stage.[3]

Hyperviscosity syndrome:

Initial treatment of Lymphoplasmacytic lymphoma:

 
 
 
 
 
Does the patient has an indication for LPL treatment?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Yes
 
 
 
No
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Does the patient has symptoms associated with hyperviscosity such as: Oronasal bleeding, blurred vision, headaches, dizziness, paresthesias, retinal vein engorgement, flame-shaped hemorrhages, papilledema, stupor or coma.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
No
 
Yes
 
For smoldering/asymptomatic WM/LPL, just follow up every 4-6 months with CBC and monoclonal protein levels
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Assess degree of symptom burden in WM/LPL pateint
 
Consider emergent plasmapheresis for treatment of hyperviscosity
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Low
 
Moderate/High
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Following are the 2 options for patients with low tumor burden with minimal symptoms:
 
Following 2 are the preferred regimens for moderate/severe symptoms or high tumor burden:
  • Bendamustine + rituximab
  • Dexamethasone & rituximab + cyclophosphamide
    •
