This includes the amplification ofERBB2 (11%) andERBB3 (5%), and mutations ofERBB2 (4%),ERBB3 (7%),KRAS (9%), andBRAF (2%).97 A whole genome sequencing of serum samples from the Korean patients diagnosed with OCCC revealed somatic mutation observed in genes that includePIK3CA (40%),ARID1A (40%), andKRAS (20%) in about 15 patients that correlates withPI3K/AKT,TP53, andERBB2 pathways.138 In a retrospective analysis,KRAS mutations were detected among the Japanese patients in cells isolated from the regions of endometriosis adjacent to the site of carcinoma. This evidence concerns the gene ARID1A and endometriosis.
