ABSTRACT

Intramedullary spinal cord metastases (ISCM) is a rare, but devastating complication of malignant disease. Prognosis is poor, with an overall median survival (OS) of 4 months from the time of diagnosis. Yet, ISCMs are being increasingly diagnosed, related to advances and increased use of imaging and therapies that prolong survival in patients with cancer. Prompt and accurate diagnosis of ISCM is necessary for effective treatment, and magnetic resonance imaging (MRI) is the preferred imaging technique. The optimal management of these patients is controversial because of the multitude of clinical circumstances and the lack of controlled studies on the efficacy of the different therapeutic approaches. Increased awareness of this rare entity may lead to an earlier diagnosis at a stage when neurological deficits are reversible, and therefore, more effective palliation may be achieved. Therefore, we carried out this retrospective research of 3 observations of ISCM, associated with a detailed review of the literature describing the diagnostic, therapeutic and evolutionary characteristics of this special rare entity.

ABSTRACT

PURPOSE: The primary objective was to determine in our department the progression-free survival rate of patients with solitary bone plasmocytoma and secondarily to evaluate its diagnostic, therapeutic and evolutionary aspects. PATIENTS AND METHODS: This is a retrospective review of 12 patients monitored and treated in the radiotherapy department of the Mohammed-V military medical teaching hospital in Rabat for a solitary bone plasmocytoma between January 2012 and December 2018. The average age of our patients were 53.8 years old (range: 31-72 years old). Pain was the most common telltale sign. The site of the lesions was spinal in four cases, iliac in four cases, mandibular, ribal, humeral and at the level of the astragalus in one case respectively. All patients received radiotherapy. This irradiation was delivered alone in 60% of cases or associated with surgery in 40% of cases. The average dose of radiotherapy was 47.3Gy (range: 45 to 50.4Gy) and this was delivered by a modulated volumetric arc therapy technique in ten patients and conformal tridimensional radiotherapy in two patients. RESULTS: Local control, defined by stability or radiological regression, was obtained in ten patients and four patients progressed to multiple myeloma, two of whom died. The average duration of follow-up was 51 months. CONCLUSION: Radiation therapy is the standard treatment for solitary bone plasmocytoma. It ensures good local control in 90% of cases. The prognosis is affected by progression to multiple myeloma, which justifies rigorous monitoring after treatment and suggests a reflection on the exact place of chemotherapy.
