OncoCare

chemotherapy for colorectal carcinoma

Wentong Xu, A.P.

The purpose of the study is to determine the relationship between change of gene copies and recurrence，and the overall survival at 5 years after chemotherapy based on clinical prognosis compared to Oncocare detection prognosis.

Colorectal cancer is the third most common cancer worldwide. About two-thirds of the patients have a good therapeutic effect by combining surgical adjuvant treatment. But there are still 30-40% of patients may relapse. Efficient relapse early surveillance and accurate treatment decisions can avoid excessive medical treatment，and keep timely intervention to tumor recurrence as well. That's very important to extend the survival of patients. Currently, the efficient surveillance tools recommended by surveillance guidelines include clinical assessment, serum carcinoembryonic antigen testing, colonoscopy and CT.

Cell-free DNA(cfDNA)，the free form of DNA in the plasma，derived from the normal cells, the abnormal cells (such as tumor cells) or external (such as viral DNA). The plasma cell-free DNA derived from tumor cells is the circulating tumour DNA(ctDNA).

As most solid tumors, including CRC, release ctDNA into the blood,precision medical applications of ctDNA liquid biopsy in colorectal cancer to predict recurrence and aid treatment decisions has become a hot topic.

Recent research shows that substantially all of colorectal cancer patients have somatic genetic alterations, including both single-base mutation and larger somatic structural variations (SSVs). Mutations in these genes can be used as biomarkers to evaluate tumor burden, predict recurrence and supply information for treatment decisions through monitor and quantify ctDNA.

In this program，sequencing the tissue from colorectal cancer patients by capture technology TM and next generation sequencing(NGS),the specific somatic mutations，the so-called biomarkers, can be found.The analysis results of sequencing can help to the study of tumor molecular pathology and supply information for targetable drug.The continuous monitoring of biomarkers in the plasma can predict recurrence and supply information for treatment decisions.

In phase I trials， recruit 200 volunteers with colorectal cancer will be recruited.the investigators will test the recurrence predicting project through OncocareTM(method mentioned above). In phase Ⅱ trials，the colorectal cancer patients will be categorized into four groups on the basis of genetic risk judged by OncocareTM and clinical risk judged by Clinical routine method. Particular emphasis is on the group of low genetic risk but high clinical risk and the group of high genetic risk but low clinical risk.

The purpose of the study is to determine the relationship between change of gene copies and recurrence，and the overall survival at 5 years after chemotherapy based on clinical prognosis compared to Oncocare detection prognosis.
