Generalized osteoblastic bony metastases from medulloblastoma
Abstract
Osteoblastic bony metastases were observed in a case of medulloblastoma three years after surgery and radiation treatment. There was clinical response to COP therapy (cytoxin, oncovin, prednisone). Radiographic and isotopic bone scan study showed uniform increase in bone density. Serum calcium and phosphorous and acid phosphatase levels were normal. Alkaline phosphatase was elevated and declined with therapy without change in the bone appearance. This suggested an increase in bone deposition activity. However, no increase in calcitonin level was detected either during active disease or following a chemotherapy-induced remission.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
