Gastric cancer(GC)is a pervasive global malignancy with high mortality rates due to distant metastasis[1].GC metastasis can occur via hematogenous route,peri-toneal route,and specifically through ovarian spread in females[2].Among these,peritoneal metastasis is the most prevalent and challenging condition to treat[3].The Cancer Genome Atlas(TCGA)has uncovered four molec-ular subtypes of GC:microsatellite instability,Epstein-Barr virus-related,chromosomal instability,and genomically stable[4].
