FAP, a classic marker of CAFs, has been associated with recurrence in patients with epithelial OC after treatment with neoadjuvant chemotherapy; strongly FAP-positive tumor parenchyma and stroma were seen in tumors from patients with high recurrence rates (OR: 15.95) while FAP-negative tumors were seen in patients with lower recurrence rates (OR: 0.086) (120). The gene discussed is FAP; the disease is neoplasm.
