Representative computed tomography (CT) restaging images depict FA, CC, and NA patients with long-lasting disease control (FA, CC, and NA represent patients' initials). Baseline CT scans at TAS-102 treatment initiation are outlined in green frames, while CT scans at the last available restaging (third for FA and CC patients, second for NA patients) are framed in blue. Measurable lesions in the peritoneum (FA: 58 mm vs 59 mm), abdominal lymph nodes (CC: 22 mm vs 0 mm; 25 mm vs 23 mm), and lungs (NA: 10 mm vs 8 mm, 6 mm and 8 mm vs 0 mm and 0 mm) are delineated by their longest diameters, with measurements in millimeters reported within the images
