Adult Gaucher disease in association with primary malignant bone tumors.
BACKGROUND
Malignant neoplastic disorders are more common in patients with Gaucher disease (GD) than in the general population. Very few cases of primary malignant bone tumors in association with GD have been reported to date. Thus, the recommendations for an adequate therapy are often based on limited professional experience. To their knowledge, the authors report the first case of a leiomyosarcoma of the bone in a patient with GD and report another patient with GD and an anaplastic large cell non-Hodgkin lymphoma with localized osseous manifestation. A review of the literature is included.


METHODS
The clinical, radiologic, and histologic data of the authors' two patients who had GD and primary malignant bone tumor are presented. Epidemiologic data, clinical data, and treatment results from published reports of 18 patients who had GD and various malignancies and the authors' 2 patients were compared and evaluated.


RESULTS
Radiographic examination showed a destructive osteolytic lesion in a case of a leiomyosarcoma of the bone and in a case of anaplastic, large-cell, non-Hodgkin lymphoma. In both cases, the bone marrow architecture was partially effaced by sheets of large histiocytic cells with striated or fibrillary cytoplasm. In both patients, chemotherapy was performed. Whereas the patient who had the leiomyosarcoma showed poor recovery of the bone marrow that necessitated withdrawal of aggressive chemotherapy, the patient who had non-Hodgkin lymphoma and enzyme therapy tolerated the chemotherapy well. In spite of local control after preoperative radiotherapy and hemipelvectomy, the first patient developed lung metastases and finally died. The second patient was continuously free of disease at a follow-up examination 32 months after chemotherapy and radiotherapy. In a total of 20 patients who had malignant disorders and GD, the numbers of males and females were equivalent, and the mean age was 55 years. Approximately 33% presented with a cancer originating in the bone. In 16 patients, follow-up data were available. Of these, after a mean follow-up of 36 months (range, few days-108 mos), only 2 patients were continuously free of disease, and one patient was alive with disease. The other patients had died of disease or hemorrhagic complications of GD.


CONCLUSIONS
Because there is a relatively high incidence of malignant disorders of the bone, the study suggested that malignant disorders have to be included in the differential diagnosis of painful lytic lesions in patients who have GD. Evaluation of the expense and value of enzyme therapy to patients who have GD should be undertaken with regard to the incidence of malignant disorders and patient survival.
