Narrator: This is Science Today. When it comes to treating prostate cancer, surgery ranks as the most cost-efficient and effective type of treatment. This, according to the most comprehensive retrospective study ever conducted. Urologist Matthew Cooperberg of the University of California, San Francisco, says their analysis compared how the major types of treatments for prostate cancer measured up to each other in terms of saving lives and cost effectiveness.
Cooperberg: The way this works is you have a hypothetical cohort of men, 10,000 men is kind of a typical number that can go down different treatment options and a variety of things can happen to them depending on what they choose. So, you kind of follow the men in this computer program basically, every month. And at every month they can be a number one — in one of a number of different states. So, they can be alive, they can be alive with their cancer, they can be cured of the cancer, they can have a recurrent cancer, they could die of the cancer or they could die of something else. It's one of the first studies that has taken the lifetime view with data that are as good as they can possibly be from the existing literature.
