Plasma Cell Neoplasms (Including Multiple Myeloma) Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment for Extramedullary Plasmacytoma

Treatment Options for Extramedullary Plasmacytoma

Treatment options for extramedullary plasmacytoma include the following:

General Information About Adult Acute Myeloid Leukemia

Incidence and Mortality Estimated new cases and deaths from acute myeloid leukemia (AML) in the United States in 2014:[1] New cases: 18,860. Deaths: 10,460. Prognosis and Survival Advances in the treatment of AML (also called acute myelogenous leukemia, acute nonlymphocytic leukemia [ANLL]) have resulted in substantially improved complete remission (CR) rates.[1] Treatment should be sufficiently aggressive to achieve CR because partial remission offers no substantial survival...

  1. Radiation therapy to the isolated lesion with fields that cover the regional lymph nodes, if possible.[1,2]
  2. In some cases, surgical resection may be considered, but it is usually followed by radiation therapy.[2]
  3. If the monoclonal (or myeloma) protein (M protein) persists or reappears, the patient may need further radiation therapy. In some patients, the plasmacytoma may shrink, but not disappear, and the M protein persists. These types of patients should be followed closely. Surgery should be performed if the plasmacytoma is in a site where it can be removed easily (e.g., in the tonsil); the M protein may disappear from the blood or urine. In other cases, persistence or an increasing M protein may herald progression to multiple myeloma.
  4. Chemotherapy is required if the disease progresses and causes symptoms.

Patients with isolated plasma cell tumors of soft tissues, most commonly occurring in the tonsils, nasopharynx, or paranasal sinuses, should have skeletal x-rays and bone marrow biopsy (both of which should be negative) and evaluation for M protein in serum and urine.[1,2,3,4]

About 25% of patients have serum and/or urine M protein; this should disappear following adequate radiation.

Extramedullary plasmacytoma is a highly curable disease with progression-free survival ranging from 70% to 87% at 10 to 14 years after treatment with radiation therapy (with or without previous resection).[1,2,5]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with extramedullary plasmacytoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
