Figure 2 shows the Kaplan-Meier survival curve for the overall survival of the patients included in this study. Patients with higher ptgs2 expression had better survival outcomes than those with low ptgs2. The Log Rank (Mantel-Cox) test for survival outcome was statistically significant (Figure 2A). The median DFS for this population was 20 (0–148) months. Low ptgs2 tumours had poorer DFS although there was no significant difference in the DFS between the two groups as shown by the Log Rank (Mantel-Cox) test (p = 0.327, Figure 2B). The gene discussed is PTGS2; the disease is neoplasm.
