Acute tumor lysis syndrome (ATLS), which occurs spontaneously, without cytotoxic therapy, is a rare condition. Spontaneous TLS (STLS) has been seen most commonly in lymphoma and leukemia. We report a series of 3 cases of STLS in patients with solid tumors who were hospitalized in our department during a 9-month period and suggest that STLS is probably more frequent than previously thought.
A 59-year-old man had well-documented agnogenic myeloid metaplasia (AMM) with pancytopenia. Frequent blood transfusions were required over a 10-month period. Androgen therapy was not beneficial and treatment with interferon resulted in severe thrombocytopenia with no decrease in transfusion requirements. Treatment with clodronate at a daily oral dose of 30 mg/kg resulted in a marked decrease in bone marrow fibrosis, and gradual normalization of blood counts over an 8-month period. He has been transfusion independent for the last 33 months. We support the findings of a previous case report that oral bisphosphonate therapy may be of value in patients with AMM.
