Tumor Lysis Syndrome*

BACKGROUND: Tumor lysis syndrome (TLS) is an oncologic emergency resulting from cancer chemotherapy; delays in its recognition could be life-threatening. Early recognition of associated risk factors and its management may help prevent its occurrence. OBJECTIVE: To identify the risk factors for TLS among cancer patients at the Philippine Children’s Medical Center. METHODS: This was a retrospective case-control study. Categorical variables were compared using chi-square test and continuous variables were compared using independent t-test. The association between TLS and patients’ characteristics was determined through logistic regression analysis. RESULTS: Medical records of 712 patients with cancer seen between 2016-2020 were reviewed. Children with (n=35) and without (n=137) TLS were selected as cases and controls and matched for age and cancer type. Factors associated with TLS are underweight patients with BMI < 18.5 (cOR 0.33, 95% CI 0.11-0.98); patients with both hepatomegaly and splenomegaly were four times more likely to develop TLS (cOR 3.946, 95% CI 1.2-12.94) while patients with lymphadenopathy were twice more likely to develop TLS (cOR 2.309, 95% CI 1.02-5.21). Patients with elevated WBC, low phosphorus and high uric acid at baseline have increased odds of developing TLS. CONCLUSIONS After group matching for age and cancer type, factors associated with increased odds of TLS among pediatric cancer patients in PCMC are hepatosplenomegaly, lymphadenopathy, elevated WBC, low potassium level, low phosphorus and high uric acid at baseline with higher fluid balance.

Introduction: Tumor lysis syndrome (TLS) is a therapy-related complication resulting from the rapid lysis of malignant cells post-treatment. The control of serum uric acid level plays a key role in its prevention, thus, allopurinol is used. Febuxostat is a novel xanthine oxidase inhibitor and there are currently no recommendations for using such in the prevention of TLS, hence, this study was conducted. This study aims to determine the efficacy of febuxostat in the prevention of TLS. Methods: Extensive search for randomized controlled trials (RCT) focusing on the use of febuxostat in the prevention of TLS was done. Each article was appraised independently by the researchers. The data were analysed using Rev Man 5.3. Results: Two trials were included in this review. The study results revealed that febuxostat, when compared to allopurinol, was able to decrease serum uric acid as hyperuricemia is the hallmark of TLS. This decrease in serum uric acid was consistent in both studies. Serum uric acid levels at the end of the treatment showed a standard mean difference of -1.09 (95% CI-1.29, -0.88, p for heterogeneity <0.01, p for effect <0.01, I2 = 97%). The trend of both studies favored the efficacy of febuxostat. The adverse effects documented during the study period in both trials were mostly noted from the chemotherapeutic agents and none from the use of febuxostat. Conclusion Febuxostat was shown to be more effective than allopurinol in the prevention of TLS.

The tumor lysis syndrome (TLS) commonly occurs in the lymphoproliferative disorder, either spontaneously or in response to therapy. TLS is uncommon in multiple myeloma. However, with the use of bortezomib in the treatment of multiple myeloma, cases of TLS have been reported. We report here threepatients who presented with TLS after the administration of bortezomib. Two of them presented mild symptoms and recovered with hydration only. However, death of the other patient was associated with TLS. We should monitor patients who had high tumor burden, especially in early phase of bortezomib therapy and appropriate prophylaxis for high risk patient is also needed.

Tumor lysis syndrome is one of the major oncological emergency. It causes complications such as acute kidney injury, cardiac arrhythmia, and death. However, it is rare in solid tumors. We report on a case of a patient with myoma of uterus who developed tumor lysis syndrome and acute kidney injury after high intensity focused ultrasound (HIFU) treatment. The potential complications of tumor lysis syndrome should be considered in HIFU treatment.

Tumor lysis syndrome is a life-threatening complication of anti-cancer therapy that typically occurs in patients with large, rapidly growing and treatment-sensitive tumors such as high-grade lymphomas and acute leukemias. However, its incidence in solid tumors has been known to be very low. Tumor lysis syndrome in solid tumors has a high mortality rate owing to the lack of prophylactic therapy to prevent this complication. We report a case of fatal tumor lysis syndrome developed during chemotherapy in extensive-stage small cell lung cancer, along with a brief review of the relevant literature considering the rarity of this manifestation in solid tumor.
