Fig. 2From: Peritoneal cell-free DNA as a sensitive biomarker for detection of peritoneal metastasis in colorectal cancer: a prospective diagnostic studyThe mutational profiling of cfDNA in matched FLD and TIS of PM and non-PM patients were compared by cluster plot. More mutations were shown in both FLD and TIS of PM patients, while no mutant in FLD in the major of non-PM patients were observed. The top five frequent gene mutations were KRAS (44%), TP53 (62%), APC(50%), PIK3CA(11%) and SMAD4(20%).
