Zusammenfassung: | Tumor lysis syndrome (TLS) is a life-threatening complication associated with cancer chemotherapy. We retrospectively evaluated the risk of developing TLS in patients with symptomatic multiple myeloma undergoing chemotherapy.
Sixty-four patients (median age=71 years, range=48-87 years, 35 males/29 females) who were treated at our Institution between April 2006 and December 2015 were evaluated.
A total of 124 chemotherapy courses were administered, of which 63 courses were bortezomib-based regimens and 34 courses were immunomodulatory drug (IMiD)-based regimens. TLS occurred in 13 (10.5%) out of 124 chemotherapy courses with five (4.0%) cases of laboratory TLS and eight (6.5%) cases of clinical TLS. The incidences of TLS were 17.5% for bortezomib-containing regimens and 3.2% for non-bortezomib-based regimens. No TLS occurred in the patients treated with IMiD-containing regimens. TLS occurred more frequently in the patients with elevated uric acid, creatinine, or beta-2-microglobulin levels at baseline. The patients with disease classified as advanced International Staging System also developed TLS more frequently. All the patients who developed clinical TLS received bortezomib-containing regimens (8/63, 12.7%). Among them, patients with elevated values of uric acid or creatinine developed clinical TLS more often than those without such elevation. The incidence of clinical TLS was 33.3% if the patients had renal dysfunction at baseline and were subsequently treated with bortezomib-based regimens (8/24 cases).
Patients with renal dysfunction or a high uric acid level receiving bortezomib-based chemotherapy have a high risk of developing TLS. |
