Abstract

OBJECTIVE:

To investigate the clinical manifestation, treatment and prognosis of extramedullary plasmacytoma(EMP) in the upper airway, and to improve the diagnosis and outcome of EMP treatment.

METHOD:

Clinical data of 26 EMP cases were reviewed retrospectively, and then compared with multiple myeloma(MM) patients presenting with lesions in upper airway.

RESULT:

Of 26 cases, 9 cases with the tumors occurred in nasal cavities, 7 in nasal sinuses, 6 in pharyngeal, 4 in throat, mainly manifesting with local masses and relevant symptoms. The manifestations of clinical, endoscopy findings and pathologic results in EMP patients were not distinguishable from the lesions of MM patients, while MM patients often accompanied by other findings, such as anemia and bone damage. Involvement of neck lymph nodes was more common in MM patients than in EMP patients. Ten patients were treated with surgery, and 16 patients with surgery and radiotherapy. Of the seven EMP patients with involvement of neck lymph nodes, four patients received additional chemotherapy besides surgery and radiotherapy, and no local relapse and MM happened in them, while of the three patients only received surgery and radiotherapy, one local relapse were found and one progressed to MM.

CONCLUSION:

The diagnosis of EMPs mainly depends on pathological results. The judgment of pathologists and application of molecular biology technology are vital for the diagnosis of EMP in upper airway, and MM must be excluded very carefully in the diagnosis of EMP. Surgery combined with radiotherapy is the main treatment for EMP in the upper airway, and the prognosis is good but the follow-up should be taken. Besides surgery and radiotherapy, chemotherapy is beneficial for the EMP patients accompanied with lesions in neck lymph nodes.
