TP53 mutations occurred within all histological subtypes except transitional and clear cell carcinomas: serous (49/64, 76.6%), endometrioid (2/5, 40.0%), mixed (2/3, 66.7%), undifferentiated (1/2, 50.0%), mucinous (1/1, 100.0%), unclassified (2/2, 100.0%) (Figure 2a–h). This evidence concerns the gene TP53 and clear cell adenocarcinoma.
