I'm hoping that immune therapies for cancer continue to improve. My dog got an experimental immunotherapy for his Hemangiosarcoma tumor (which is incurable). Due to the advanced state of the tumor (he had to have his spleen removed in emergency surgery due to the tumor, plus it had spread to other organs), he was given a 2 - 4 month survival time, he's on month 4 now.

There's not enough data to say if the immune therapy is helping (he's on traditional low-dose chemo as well), but it seems promising. The company (Torigen.com) is focused on animal treatment for now, but sees applications for humans in the future.
