Secondary objectives:
Molecular residual disease clearance as assessed by SIGNATERA™
Percent of patients undergoing surgery for oligometastatic recurrence
Survival in patients treated with adjuvant versus no adjuvant chemotherapy in patients with SIGNATERA™ negative test results
Overall survival
Impact of SIGNATERA™ test results on patient quality of life
