TPD52 and endometrioid adenocarcinoma: In contrast, high-level TPD52 staining was most frequent in clear cell carcinomas (8/8, 100%), followed by mucinous (8/10, 80%) serous (115/167, 69%), and endometrioid carcinomas (9/19, 47%) (Fig. 3b), with clear cell carcinomas also displaying the highest median TPD52 SPC (Table 3).
