Is CLL more common in certain groups or demographics?
The disease is more common in the Western countries. So in the Eastern countries, it is less prevalent. The Eastern countries are including Japan, China—in these countries the prevalence of CLL is lower. In general, it is more common in men than in women, and it is usually diagnosed in elderly patients. The median age of diagnosis is around 72 years in Western countries. We do not have a specific ethnic prevalence in CLL. Of course, It is, as mentioned, the less prevalent in the eastern countries. So, we are still trying to understand if this is related to the genetic background or to the environmental background, studying people who moved from Eastern Countries to Western countries. But it seems that there is a genetic predisposition to the disease this is not an hereditary disease. CLL is a disease that tends to affect older individuals. The average person, at least in the United States, who's diagnosed is around 70 years of age. That doesn't mean we don't see it in younger people, but it's you know, as you get into younger and younger groups, it becomes very uncommon. In the elderly, in people in their eighties and nineties, it is quite common. Chronic lymphocytic leukemia is a disease that affects an older population of patients. These patients are often in their sixties and seventies. It is slightly more common in males and females and slightly more common in Caucasian populations than in other ethnic groups. It also is slightly more common in people who have other hematologic malignancies as well.
