Frequency distribution of ROR scores. (A) Frequency distribution of ROR1 scores in tumor cells by subtype (from left to right: serous, mucinous invasive, endometrioid, clear cell, and mucinous borderline). (B) Frequency distribution of ROR1 scores in stroma by subtype (from left to right: serous, mucinous invasive, endometrioid, clear cell, and mucinous borderline). (C) Frequency distribution of ROR2 scores in tumor cells by subtype (from left to right: serous, mucinous invasive, endometrioid, clear cell, and mucinous borderline).
