Figure Lengend Snippet: Overall Survival (OS) of patients with Leptomeningeal Metastasis (LM) from the whole cohort and Kaplan–Meier estimates based on clinical characteristics. A The median OS (mOS) of all the patients after diagnosis of LM was 8.0 months. B Patients with high Karnofsky Performance Status scores had better mOS (> 60 versus ≤ 60: 9.0 versus 5.0 months, hazard ratio [HR]: 0.60, P = 0.005). C Patients who had extensive systemic disease with few treatment options had slightly higher mOS (8.0 versus 6.0 months, HR: 0.65, P = 0.014). D Patients who received more than six times of intrathecal pemetrexed (IP) had better mOS (> 6 versus ≤ 6: 14.0 versus 5.0 months, HR: 0.41, P < 0.001). E Patients with response for IP treatment had better mOS (effective versus non-effective: 8.0 versus 4.0 months, HR: 0.50, P < 0.001). F Continued negative cerebrospinal fluid cytology after treatment was associated with longer survival (mOS 11.0 versus 5.0 months, HR: 0.42, P < 0.001)
Article Snippet: Pemetrexed (Alimta, Eli Lilly and Company, 100 mg) was dissolved in a 0.9% sodium chloride solution (3–5 mL) and prepared into a 50-mL mixture.
