Age Question/Longevity Histio
My heart just breaks to see the roll call of histio victims - and I know there are many more to come. Many of the names are familiar to me only through this list, some I have known personally. I was just wondering, if about 1 in 6 berners dies from histio, and if we took the histio deaths out of the longevity statistics, I wonder what the average age would be then? That figure may make the importance of the histio genetic study a little more obvious. Valerie
Re: Age Question/Longevity Histio
Valerie, I think you'll be very surprised! The average age at time of death for histio was 89.7 months, and the overall average was 84.43 months. So if we remove histio as part of the average age calculation, the average age at time of death - would go down! But if we find a way to prevent histio, then those dogs would live even longer, thereby increasing the average lifespan. The cancer that really hurts us is lymphoma.

Re: Age Question/Longevity Histio
The cancer that really hurts us is lymphoma. It is my understanding that lymphoma is the most common cancer in dogs in general. I'm not sure if there is a heritable component to it or not. It's really hard to determine this when a dog dies of it and produces the breed average for it. I don't know that it would really be determinable even if the dog produced a higher than average incidence of it. But in such a case I'd be leaning in the direction of a heritable component to its occurence. Ruth Reynolds

Pat does the curve tell us anything? SOMETHING takes a sizeable number of our dogs young.. -Sherri Venditti

That might have been a conclusion that was drawn by the research team. I can't say. Regardless, I do not consider that or any other study to be a definitive study to eliminate heredity as a factor in other cancers in our breed. In fact, I suspect in time we'll find out there are other cancers which are indeed hereditary in our breed. Ruth Reynolds
RE: Age Question/Longevity Histio
I had some ISP problems, I'm playing catch-up here, forgive me if things have already been answered. Dr. Padgett and a group studied several types of cancer, and were able to conclude at that time that only histio and mast cell definitely had a hereditary basis in the breed. He is studying hemangiosarcoma and one other type of cancer at the present time, and he is not yet ready to make any hard and fast conclusions. Pat Long ( Luther) Berwyn PA
