What is the life expectancy of someone with mycosis fungoides?

The overall survival and disease-specific survivals of our 525 patients with MF are shown in Figure 1. The median survival was 11.4 years, and the actuarial overall survival rates at 5, 10, and 30 years were 68%, 53%, and 17%, respectively. The median follow-up time was 5.5 years (range, 0.1-38.5 years).
