Table 2.

FR-α expression subdivided into histology (top 3 rows, complete cohort; middle 3 rows, serous carcinoma; bottom 3 rows, non-serous carcinoma). Each group is subdivided into samples obtained at primary surgery, at interval debulking surgery or at surgery for recurrent disease. Expression scores are depicted as percentages
