- Decrease in Tumor Size. [ Time Frame: 18 months ]Response rate is measured by PET-CT scan (a decrease in standardized uptake value (SUV) by 25%), Response Evaluation Criteria in Solid Tumors (RECIST), and Choi criteria (10% decrease in tumor size or a 15% decrease in tumor density on contrast-enhanced CT, computed tomography, scan).
- Time to Progression (TTP). [ Time Frame: two years ]
