Statistics are interesting and fun, but boy, are they easily manipulated and thus, often meaningless.
One suggestion for checking stats is to check with your local tumor board/hospital/oncologists/cancer center. The statistics close to home are probably still skewed because of demographics, but they may be more current and responding to the treatments at your specific center.
When I was diagnosed, the surgeon had just returned from a Northern California convention with nationwide statistics (supposedly recent) and also the local hospital's statistics. They were both pretty scarry, but slightly different from each other.
For me, statistics are just one piece of the puzzle. Another is my response to treatment, age, general health, information/education, support system, diet, exercise, etc.
