Detailed Description
PRIMARY OBJECTIVES:
I. To establish the rate of circulating tumor elements (CTE), including but not limited to circulating tumor cells and circulating tumor deoxyribonucleic acid (DNA) detection in patients with locally advanced rectal cancer (LARC), relative to other stages.
II. To assess changes in detected CTEs associated with neoadjuvant therapy in patients with LARC.
III. To correlate CTEs with neoadjuvant treatment response as an indicator of disease risk.
OUTLINE:
Patients and healthy participants undergo collection of blood sample at baseline. Patients may also undergo collection of blood sample collections during tumor surgery, 4 weeks after surgery or after completion of treatment if you are not surgery, 8 weeks after the last dose of chemotherapy, 1 year after surgery or 1 year after completion of treatment if not having surgery, 2 years after surgery or 2 years after completion of treatment if not having surgery, and within 6 years after treatment or at the end of the 6 year follow-up if the disease gets worse with treatment or comes back.

Ancillary-Correlative (biospecimen collection)
Patients and healthy participants undergo collection of blood sample at baseline.
Patients may also undergo collection of blood sample collections during tumor surgery, 4 weeks after surgery or after completion of treatment if you are not surgery, 8 weeks after the last dose of chemotherapy, 1 year after surgery or 1 year after completion of treatment if not having surgery, 2 years after surgery or 2 years after completion of treatment if not having surgery, and within 6 years after treatment or at the end of the 6 year follow-up if the disease gets worse with treatment or comes back.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Proportion of treatment naive locally advanced rectal cancer (LARC) patients with circulating tumor cells (CTC)
Time Frame: Baseline up to 6 years
|
The proportion of patients with any CTC will be calculated with a 95% confidence interval (CI).
Additionally, the actual CTC count will be plotted with a box-plot.
Proportions of patients with 2 or more, and 3 or more CTCs will be calculated.
Will also explore correlations between the presence of 1 or more CTC and primary tumor characteristics using Chi-Squared or Fischer's exact tests as appropriate.
|
Baseline up to 6 years
|
Change in circulating tumor cells status
Time Frame: Baseline and 8 weeks after completion of treatment
|
A McNemar's test will be used to test whether neoadjuvant therapy (NEO) provided any improvement in the proportion of patients with any CTC.
The CTC counts at baseline versus 8 weeks after completion of treatment will be compared with a paired t-test.

Baseline and 8 weeks after completion of treatment
