Abstract

Objectives: To describe the incidence, treatment and outcomes associated with tumor lysis syndrome (TLS) in women with gynecologic cancer (GOC).

Methods: A retrospective multi-institutional review of TLS associated with GOC. Women presenting with an elevated serum uric acid managed with intravenous (IV) rasburicase were included. Descriptive statistics of patient demographics, clinical findings, and outcome data was completed.

Results: From two large academic institutions N = 18 patients were found to meet inclusion criteria from 2008 to 2018, reflecting an approximate 5% incidence of clinically treated TLS associated with GOC in our cohort. Median age was 60 years, a majority were Caucasian (n = 11, 61.1%), median BMI was 36.2. TLS was associated with a high-grade GOC in n = 17 (94.4%) cases. TLS was commonly diagnosed with a new GOC (n = 12, 70.6%) and following receipt of chemotherapy in n = 9 (50.0%) cases. Six (66.7%) patients were treated with paclitaxel or combination, five (55.5%) with a platinum or combination, and two (22.2%) with a CD47 inhibitor. Chief complaints included electrolyte and renal abnormalities (n = 11, 73.3%). Peak serum uric acid, potassium, creatinine and phosphorus levels were 14.1 mg/dL, 5.7 mEq/L, 5.1 mg/dL, and 6.8 mg/dL, respectively. Nine patients received hospice during their admission with 3 (20%) deaths occurring as inpatients. There were 12 deaths with median OS of 16 d (range: 2-87 d).

Conclusions: Though rare, TLS can be associated with GOC. Early recognition of presenting symptoms, laboratory findings and expedited treatment may help with electrolyte recovery; however, TLS associated with GOC may herald a rapidly deteriorating state with significant associated mortality.
