In addition, multivariate Cox regression analysis showed that primary therapy outcome (HR = 0.365, CI: 0.237–0.563, p < 0.001) and tumor status (HR = 19.162, CI: 4.689–78.307, p < 0.001) were independent prognostic factors of OS for HGSOC; SPOCK2 expression level, however, was not still an independent factor related to OS (HR = 1.297, CI: 0.939–1.791, p = 0.114) (Figure 5B, Supplementary Table S1). The gene discussed is SPOCK2; the disease is neoplasm.
