Recently the investigative program, W5, aired a segment on canine cancer treatments, and how they are lending knowledge to humans.

As reported by W5: “Most dogs that develop osteosarcoma aren’t cured when the tumours are removed because the cancer usually spreads to other parts of the body. But in a pilot study, this listeria vaccine showed great promise.”..1

Approximately 90% to 95% of dogs with osteosarcoma have micrometastases at diagnosis and despite limb amputation and adjuvant chemotherapy, most are euthanized due to progressive metastatic disease within 1 year of diagnosis…2

The study showed in some dogs there was a marked delay in the return of cancer and even extended the lives of some patients by 1-2 years longer than those that didn’t receive the vaccine.

Watch the W5 clip above.
