Refractory Plasma Cell Neoplasms

Plasma cell neoplasms are called refractory when the number of plasma cells keeps going up even though treatment is given.

Read the Refractory Plasma Cell Neoplasms article > >

Treatment of LCH is based on where LCH cells are found in the body and whether one or more body systems are affected.

LCH is described as single-system disease or multisystem disease, depending on how many body systems are affected:

  • Single-system LCH: LCH is found in one part of an organ or body system (unifocal) or in more than one part of that organ or body system (multifocal).
  • Multisystem LCH: LCH occurs in two or more organs or body systems.

LCH may affect low-risk organs or high-risk organs, depending on where it occurs in the body:

  • Low-risk organs include the skin, bone, lymph nodes, gastrointestinal tract, pituitary gland, and central nervous system (CNS).
  • High-risk organs include the liver, spleen, and bone marrow.
