Table 1. Distribution of patients with colorectal cancer into groups depending on the levels of cell-free DNA circulating in their blood plasma before surgery and detection of cancer-associated mutations of the RAS genes by allele-specific real-time PCR
Note. Data are presented as median (Q1–Q3). Significance of difference was tested by comparing groups of patients with and without mutations in the RAS genes. * represents significant difference.
Table 2. Progression of colorectal cancer in patients characterized by cfDNA levels in their blood plasma measured prior to surgery and detection of cancer-associated mutations of the RAS genes by allele-specific real-time PCR
Note. Data are presented as median (Q1–Q3). Significance of difference was tested by comparing groups of patients with and without mutations in the RAS genes. * represents significant difference.
