Study Arms:
- Group A - 3 FDG-PET/CT Scans (Type: EXPERIMENTAL): Two FDG-PET/CT scans prior to 1st cycle of chemotherapy, plus 2 optional volumetric CT scans. One FDG-PET/CT after 1st cycle of chemotherapy, plus 1 optional volumetric CT scan.
- Group B - 2 FDG-PET/CT + 1 Optional (Type: EXPERIMENTAL): One FDG-PET/CT prior to 1st cycle of chemotherapy; 1 FDG-PET/CT after the 1st cycle of chemotherapy; 1 optional FDG-PET/CT after the 2nd cycle of chemotherapy. All three with optional volumetric CT scans.
- Group C - Test-Retest (Type: EXPERIMENTAL): Test-retest sequence for FDG-PET/CT; two scans with optional volumetric CT to be completed prior to 1st cycle of chemotherapy.

Based on this trial design, predict the completion outcome and termination type (if applicable).
