ObjectiveTo investigate the prevalence of p53 mutations and associated factors between immunohistochemistry (IHC) and p53staining patterns among patients with high-grade serous ovarian carcinoma (HGSOC). MethodsThis study is a retrospective review. A total of 62 patients with HGSOC underwent surgery at Srinagarind Hospitalbetween January 2016 and December 2020. Histological examination was performed based on a combination ofmorphology and IHC staining with p53. The p53 immunostaining pattern was interpreted as a missense mutation,nonsense mutation, or a wild-type pattern. Missense (p53 overexpression pattern) and nonsense (null expression p53pattern) mutations were considered p53 mutations. A wild-type pattern was defined as a p53 non-mutation. Resultsp53 mutations were identified in 93.6% of the patients. Subgroup analysis of the p53 mutation group betweenthe p53 overexpression pattern and the p53 null expression pattern in terms of clinicopathological characteristicsand initial treatment was performed. Patients with the p53 overexpression pattern had significantly more omentalmetastases than those with the p53 null expression pattern (87.8% vs. 64.7%, P=0.042). There were no statisticallysignificant differences in median progression-free survival (PFS) (9 vs. 10 months, P=0.813) or median overall survival(OS) (12 vs. 17 months, P=0.526) between the two groups. ConclusionThe prevalence of p53 mutations in HGSOC patients in this study was 93.6%. Omental metastasis is a significantpathological factor in predicting overexpression p53 pattern in HGSC. However, IHC analysis of the p53 stainingpattern did not affect OS or PFS among patients with HGSOC.
