Patients and Methods: We included 19 patients with mCRC who received TAS-102 and bevacizumab combination therapy biweekly as third-line chemotherapy. The primary endpoint was progression-free survival. Results: Patients had a median age of 73 years and most (73.4%) were men. The median progression-free and overall survival were 5.6 and 11.5 months, respectively. Five (26.3%) patients achieved a response and the disease control rate was 12/19 (63.1%). One patient (5.2%) experienced neutropenia grade 3 or more. The median time from baseline performance status 0/1 to worsening to 2 or more was 10.3 months. Conclusion: Biweekly TAS-102 plus bevacizumab facilitates tumor shrinkage by reducing the incidence of grade 3 or more neutropenia, improving survival, and maintaining performance status. This combination may represent a treatment option for patients with late-stage mCRC receiving third- or later-line therapy. ER -
