Patients about to receive chemotherapy for a cancer with high cell turnover rate, especially lymphomas and leukemias, should receive prophylactic oral or IV [[allopurinol]] (a [[xanthine oxidase]] inhibitor, which inhibits uric acid production) as well as adequate IV hydration to maintain a high urine output (> 2.5 L/day). [[Rasburicase]] (Uricase) is an alternative to allopurinol and is reserved for patients who are high-risk in developing TLS. It is a synthetic [[urate oxidase]] enzyme and acts by degrading uric acid. Alkalinization of the urine with [[acetazolamide]] or [[sodium bicarbonate]] is controversial. Routine alkalinization of urine above pH of 7.0 is not recommended. Alkalinization is also not required if uricase is used.
Before initiating chemotherapy for cancer patients, especially lymphomas and leukemias, should receive the following:

*Adequate IV hydration to maintain a high urine output (> 2.5 L/day)
*[[Rasburicase]] (Uricase) is an alternative to allopurinol and is reserved for patients who are high-risk in developing TLS.

Overview

Effective measures for the primary prevention of tumor lysis syndrome include allopurinol, rasburicase, and IV hydration.

Prevention

Before initiating chemotherapy for cancer patients, especially lymphomas and leukemias, should receive the following:

  • Allopurinol
  • Adequate IV hydration to maintain a high urine output (> 2.5 L/day)
  • Rasburicase (Uricase) is an alternative to allopurinol and is reserved for patients who are high-risk in developing TLS.
  • Alkalinization of the urine with acetazolamide or sodium bicarbonate is controversial
