Abstract
Background
Tumor lysis syndrome (TLS) is a known oncologic emergency characterized by severe metabolic derangements. TLS has been well documented in patients with hematologic malignancies, but rarely with metastatic melanoma. The objective of this study was to investigate the clinical characteristics and outcomes of TLS with metastatic melanoma.
Methods
Retrospective literature review and analysis.
Results
Eighteen cases of TLS were identified with metastatic melanoma from published literature. The median age of patients was 63 years (36-79 years). All patients have stage IV disease. Seven cases (39%) of TLS were associated with multiple treatment regimes, including nivolumab (22%), ipilimumab (16%), and dacarbazine (22%). The time from treatment to diagnosis was 3.5 days (8 hours-21 days) in treatment-related TLS. Three cases (17%) were due to spontaneous TLS. The majority of cases have a high tumor burden (77.5%) and liver metastasis (83%). Seven cases were treated with rasburicase (39%). The mortality rate was 100% for the patients with spontaneous TLS and 73% for patients with treatment-related TLS. Three cases utilized traditional chemotherapy and the six most recent cases of treatment-associated TLS utilized immunotherapy and targeted therapy.
Conclusion
TLS in metastatic melanoma, due to either spontaneous or treatment-related causes, is associated with a very high mortality rate. This study highlights the importance of awareness, early intervention, and risk assessment of this underdiagnosed emergency.
