[The toxicity profile of TAS-102. Practical considerations about neutropenia.]

Abstract

TAS-102 represents an important therapeutic resource for patients with metastatic refractory colorectal cancer. Albeit generally well tolerated, clinically relevant neutropenia may interfere with the regular delivery of full-dose cycles with a possible detrimental effect on the dose-intensity. Judicious and personalized use of colony-stimulating growth factors as well as alterative schedules of drug delivery could mitigate neutropenia, so contributing to an even better therapeutic index of the drug.
