St. Jude shows gene test not needed if cancer drug given in low doses
...ldren's Research Hospital have shown that when the cancer
drug irinotecan is given in low doses for multiple days, it eliminates the need to delay treatment to perform costly genetic testing that determines if the patient is at risk for serious treatment side effects, such as neutropenia. Neutropenia is an ...
