We investigated the relationship between the three subtypes and various well‐known oncogenic genes and tumour suppressors in ovarian cancer from cBioPortal and found EIF5A2 (P < 0.001), FGF1 (P < 0.001) and EGFR (P = 0.002) were highly expressed in the CAFs‐immune subtype. Here, FGF1 is linked to ovarian cancer.
