title: Solitary plasmacytoma of the spine: relationship of IGM to tumour progression and recurrence.
abstract: The authors report a retrospective study of 15 patients with solitary vertebral plasmacytoma. 15 patients were considered in this study on the basis of the following characteristics: 1) histologically confirmed plasmacytoma following surgical removal; 2) existence of a single vertebral lesion, documented by skeletal and MRI scan; 3) no signs, at diagnosis of disseminated disease by blood laboratory test, urine analysis, sternal puncture, iliac bone marrow biopsy, a total-body CT scan. The clinical course of the patients has been analysed on the basis of the following factors: age, sex, length of clinical history before diagnosis, site, presence/absence of the M component. The M component is an electrophoretically homogeneous immunoglobin. The most significant factors for predicting development of multiple myeloma proved to be the presence /absence of the M component at diagnosis and, to a lesser degree, the age of the patient. In the light of other reports too, it would seem that the presence of the M component at diagnosis is a reflection of aggressive biological and clinical tumour behaviour.
