We categorized EC tumors based on histological type (low-grade EEC vs. other EC subtypes), MMR status (MMR-deficient vs. MMR-proficient), size (≤2 cm vs. > 2 cm), and presence of myometrial invasion and compared the cervicovaginal levels of protein biomarkers between these subgroups (Fig. 6A and Supplementary Fig. S5). The gene discussed is MRC1; the disease is exstrophy-epispadias complex.
