Brief Summary:
The investigators will detect circulating tumor DNA in blood of patients with lung metastases from colorectal cancer using NGS technology and intend to use it for predicting the outcome of local treatment (surgery or radiation) and recurrence of lung metastases.
Detailed Description:
The investigators produce customized gene target panel by selecting genes that are commonly found in colorectal cancer and metastasis from existing literature.
In patients diagnosed with lung metastases from colorectal cancer, 20mL of whole blood is collected before and after local treatment (surgery or radiation) and cell-free DNA (cfDNA) is extracted from the collected blood. Thereafter, 20 mL of whole blood is additionally collected once after 3 months (±2 months) and once after 6 months (±2 months) during follow-up and cfDNA is extracted. The investigators perform sequencing from the extracted cfDNA.
The investigators compare the mutations detected in cfDNA before and after local treatment and identify the trend of reducing mutations in cfDNA after local treatment. So The investigators discover biomarkers for the outcome of local treatment. The investigators also search for mutations for target drugs from mutation profiling of cfDNA.
