Notification of this interview came out a fortnight ago, but I've posted the link here should anyone wish to discuss this video or treatment for elderly CLL patients in general:
Not long ago, younger patients received the most aggressive CLL treatment, which gave them the greatest chance for long-term disease control, and elderly patients were given less-effective palliative care. Now therapies are targeted, have fewer side effects and are suitable for the older patient, giving them the same chance of a longer life. Dr. Valentin Goede, a hematologist/oncologist and gerontologist who specializes in CLL care at the University of Cologne in Germany, explains how this is a much more positive time for elderly people with CLL.
