TP53 and serous adenocarcinoma: p53 staining based on its mutational status was observed differentially expressed in high‐grade serous carcinoma (P < .001), lymphatic vascular invasion (P = .008), bilateral involvement (P < .001), necrosis (P < .001), ovarian surface involvement (P = .001), stage (P = .001), death (P = .045), and recurrence (P = .022).
