Furthermore, based on the results of immunotyping of pancancer in the literature [21], we compared the relationship between risk score and immunotyping of ovarian cancer, and found that there were significant differences between the three existing immune subtypes C1 (wood healing), C2 (IFN gamma dominant), C4 (lymphocyte completed) and risk score in TCGA data set of ovarian cancer. Here, IFNG is linked to ovarian cancer.
