Overall survival according to applied lines of systemic therapy. Survival rates were calculated from date of diagnosis. Median survival significantly improved with increasing numbers of lines of systemic therapy (p < 0.001). Patients with 0–6 lines of systemic treatment had a median survival of 2.0, 5.3, 8.7, 13.0, 14.1, 21.8, and 39.1 months, respectively.
