The median survival time of the whole group was 15 months, of which the effective median survival time was 20.5 months and the median effective life span was 8 months. There was a significant difference between the two groups (P = 0.013). The 1, 2, 3 year survival rates were 66.7%, 40.0% and 20.0% respectively.
