Objectives
Narrative objectives1
The purpose of this study is threefold. To evaluate the efficacy of preoperative chemoradiation in patients with locally advanced rectal cancer.
1) To determine whether plasma and urine cell free DNA levels and the presence or absence of RAS and p53 mutations are useful for predicting response in pretreatment liquid biopsy.
2) To evaluate whether cell free DNA levels and mutation allele frequency (MAF) in preoperative chemoradiation, at the end of each course, and in postoperative liquid biopsy are predictive of response to nCRT.
(3) To follow the changes of cell free DNA level and MAF in patients with clinical complete response (cCR) and to examine the relationship with relapse and prognosis.

Assessment
Primary outcomes
The correlation of the dose of ctDNA and exosome DNA during treatment and the survival.
Key secondary outcomes
Correlation between ctDNA and exosome DNA amounts before, during, and after treatment and recurrence-free survival time
Correlation between ctDNA, exosome DNA amount and tumor markers
Correlation between ctDNA, exosome DNA amount, response rate of neoadjuvant chemotherapy (RECIST Ver1.1), and disease control
Correlation between the amount of ctDNA and exosome DNA and the rate of decrease in the SUVmax value of the primary tumor determined by PET-CT examination
Correlation between ctDNA, exosome DNA amount and histological treatment effect (grade based on tumor cell disappearance rate according to Evans criteria)
Correlation between ctDNA, exosome DNA amount and resection rate
ctDNA, exosome DNA amount and radical resection rate (R1 or R0; R1: state with no macroscopic residual cancer, R0: state with no histological residual cancer)
Comparative study of the amount of ctDNA and exosome DNA of the target gene and immunostaining results in surgical resection specimens
