Abbreviations: EC=grade 1 endometrioid carcinoma; HGSC=high-grade serous carcinoma.
In cluster A, by histological type, 14 of 16 tumour samples were ECs and only 2 were HGSCs. In cluster B, 7 of 8 samples were HGSCs and only 1 was EC (P=0.0007). However, by organs, in cluster A, 10 of the 16 samples were from endometrial cancer and 6 of 10 were ovarian cancer. In cluster B, 4 of 8 samples were ovarian cancer and 4 were endometrial cancer (P=0.6734).
