Prophylactic use of pegfilgrastim enables the management of severe neutropenia without dose delays in patients with metastatic colorectal cancer treated with TAS‑102 plus bevacizumab

Combined treatment with bevacizumab and trifluridine/tipiracil (TAS-102) leads to an increased chance of survival in patients with refractory metastatic colorectal cancer (mCRC); however, this treatment is associated with an increased frequency of severe neutropenia (number of neutrophils1,000), which should ideally be managed without dose delays. The present study provided a retrospective review of 35 patients with mCRC, and aimed to elucidate the benefits of prophylactic pegfilgrastim for the treatment of severe neutropenia. Patients received TAS-102 (35 mg/m
