Brief Summary:
This phase II/III trial studies how well circulating tumor deoxyribonucleic acid (ctDNA) testing in the blood works in predicting treatment for patients with stage IIA colon cancer after surgery. ctDNA are circulating tumor cells that are shed by tumors into the blood. Finding ctDNA in the blood means that there is very likely some small amounts of cancer that remain after surgery. However, this cancer, if detected, cannot be found on other tests usually used to find cancer, as it is too small. Testing for ctDNA levels may help identify patients with colon cancer after surgery who do benefit, and those who do not benefit, from receiving chemotherapy.
Detailed Description:
PRIMARY OBJECTIVES:
I. To compare the rate of ctDNA clearance in "ctDNA detected" patients treated with or without adjuvant chemotherapy following resection of stage IIA colon cancer. (Phase II) II. To compare recurrence-free survival (RFS) in "ctDNA detected" patients treated with or without adjuvant chemotherapy following resection of stage IIA colon cancer. (Phase III)
SECONDARY OBJECTIVES:
I. To describe the prevalence of detectable ctDNA in patients with stage IIA colon cancer following surgical resection.
II. To estimate time-to-event outcomes (overall survival \[OS\], recurrence-free survival \[RFS\], and time to recurrence \[TTR\]) by ctDNA marker status and treatment for patients with resected stage IIA colon cancer.
III. To estimate the rate of compliance with adjuvant chemotherapy and/or active surveillance for patients with resected stage IIA colon cancer.
