Osteosarcoma: Beyond amputation and euthanasiaMarch 12, 2019When a patient is diagnosed with osteosarcoma, we tend to focus on three options: • the "gold standard," i.e. amputation with or without chemotherapy; • what many call palliative care, meaning pain medication and rest; or • euthanasia. But what if amputation is not an option? What if chemotherapy or radiation is out of the owner's financial capabilities? Or a couple of medications are not enough to numb the pain? What if visible metastasis to the lungs is already present? Bob Stein, DVM, pain management guru and founder of the Veterinary Anesthesia & Analgesia Support Group (www.vasg.org), recently shared another valid option.* "With my suggested approach, we can often provide quality of life to even large-breed dogs for six to 12 months and sometimes more than 20." Let's detail Dr. Stein's protocol. Pamidronate Pamidronate, a bisphosphonate, is an injectable drug that is inexpensive and easy to administer (ref: TM Fan et al. JVIM 2007). It helps to reduce pain (in 30 to 50 percent of patients), inhibit bone osteolysis, and has potential cancer-suppression effects by impeding proliferation and inducing apoptosis. The drug has a wide safety margin and can even be used on patients with renal or …

ISU to begin canine anticancer immunotherapeutic agent clinical trialsFebruary 28, 2019Iowa State University (ISU) College of Veterinary Medicine is starting a clinical study for a new canine anticancer immunotherapeutic. Produced by NovaVive, the anticancer treatment, Immunocidin, has received regulatory approval in the U.S. and Canada to treat mammary tumors. The study will observe dogs with stage I or stage II splenic hemangiosarcoma (HSA) who have undergone a splenectomy to determine the effectiveness of Immunocidin in combination with doxorubicin chemotherapy. Sixty-six dogs will participate in the trial and survival times will be monitored. "Treatment options and survival outcomes for canine HSA have remained essentially stagnant for the past two decades," said Chad Johannes, DVM, DACVIM (SAIM, oncology). "Additional therapeutic options for HSA are needed and we look forward to learning more about how immune stimulation via Immunocidin may play a role in improving outcomes for dogs." Ten oncology clinics will participate in the trial. To find one, visit bit.ly/2D56wBv and enter AAHSD004874 in the keyword search.
10 golden rules of cancer surgeryFebruary 20, 2019Surgery plays a critical role in the management of cancer. One significant advantage of surgery is a chance at an immediate cure—after a single session. No other treatment modality can offer that. Here are 10 rules that must be followed to ensure the best possible surgical outcome. Do the math: Surgery is only 10 percent of the entire story. What follows mainly pertains to skin masses, but it applies to any tumor, even intrathoracic or intra-abdominal. 1) Client communication Whenever a mass is discovered, it is important to take the time to prepare the client for the worst, while hoping for the best. Don't sugarcoat things. Don't make assumptions. Don't claim to have microscopic vision. Don't overpromise. Remember, for example, that a mast cell tumor is called "the great imitator" for a reason. It can feel like anything, including a lipoma. 2) Preop workup Even though we typically say you can't diagnose cancer by looking at blood work, it will occasionally show abnormalities, such as infection, hypercalcemia, or increased liver values. Staging the patient (i.e. determining the extent of the disease) is a mandatory part of the preop workup. Before surgery is ever considered, perform three views of the thorax …
Compounded drugs—A literature updateJanuary 2, 2019In exciting times of new approved drug formulations for animal species, veterinarians face a myriad of challenges when balancing optimal treatment protocols and overall cost burden. Compounded drugs may offer an enticing alternative to an approved animal drug in terms of palatability and cost to the owner; however, the legal status of compounded drugs is often difficult to evaluate.
The race to develop immunotherapies for canine lymphoma and osteosarcomaJanuary 2, 2019There are many reasons why development of immunotherapies in dogs has been slow. Although cancer, and in particular lymphoma and osteosarcoma, is frequent in dogs, just one percent of owners have pet insurance; those who don’t are willing to spend only a limited amount of money to treat their dog, especially when initial treatment results are not as dramatic as in humans.
