- Abstract
Objective Tumor-lysis syndrome is a rare complication in patients with multiple myeloma. However, bortezomib treatment for myeloma is often associated with tumor-lysis syndrome. Methods We developed an index called the rapid anemia progression index, which represents the duration and progression of anemia, to evaluate risk factors for tumor-lysis syndrome. We retrospectively reviewed 35 relapsed or refractory myeloma patients treated with bortezomib-containing treatment in our institution. We analyzed various parameters, including albumin, lactase dehydrogenase, β2-microglobulin and creatinine, similar to the rapid anemia progression index, and evaluated the risk factors for tumor-lysis syndrome associated with bortezomib by the Cairo–Bishop definition. Results Clinical tumor-lysis syndrome occurred in six patients (17.1%). Tumor-lysis syndrome occurred during the first course of bortezomib-containing treatment among all the patients. The result of the area under the receiver operating characteristic curve for the rapid anemia progression index was 0.759 (P = 0.049). The rapid anemia progression index was more accurate than the index of lactate dehydrogenase, β2-microglobulin, albumin and creatinine according to the receiver operating characteristic curve. For a cut-off point of −1.12 for the rapid anemia progression index, the sensitivity and specificity were 66.7 and 82.8%, respectively. Conclusions The rapid anemia progression index is related to clinical tumor-lysis syndrome associated with bortezomib treatment for multiple myeloma patients with a cut-off point of −1.12 g/dl/month.
