Just saw this article in the Coloradoan Newspaper about a new clinical study in Fort Collins:

CSU cancer researchers are seeking dogs with specific types of cancer to participate in a trial of an experimental treatment.

The team is looking for dogs with soft tissue sarcomas and malignant histiocytosis, called MH, to enroll in the clinical trial.

Dogs with MH are often given a prognosis of only two to three months without treatment. These tumors are highly resistant to chemotherapy, and other options for treatment are limited. Dogs with soft tissue sarcomas, which are often located on limbs, have more options, such as surgery, amputation and radiation. They also are typically given a longer prognosis of six months to a few years.

The study is investigating the impact of a drug on cells that suppress the immune system and allow cancer tumors to grow. Initial results in mice and dogs show that the drug can reverse suppression of the immune system and halt tumor growth in dogs and, in some cases, even shrink tumors.

Here's a link to the CSU website page about this study.
