Should My Dog Get The Cadet Braf Test

Transitional Cell Carcinoma in Dogs (TCC)

Although all breeds of dogs can develop bladder cancer, it is relatively rare. However, if you own a high-risk breed, it might be worth talking to your veterinarian about the CADET Braf test, especially as your dog enters his senior years. Dr. Arteaga recommends all at-risk breeds have the screening test after age 8, and Dr. Sigmon recommends that dogs over 6 years old with a history of multiple episodes of bloody urine get tested for bladder cancer. She also advises breeders of at-risk breeds to invest in an annual subscription of the CADET Braf Mutation Assay to help monitor bladder cancer within their breeding programs.

For more questions about your dogs risk of bladder cancer and the CADET Braf test, talk to your veterinarian or visit SentinelBiomedical.com.

What Can Owners Do To Prevent Bladder Cancer

If you own a high-risk breed, youre probably wondering if there is anything you can do to lower your dogs risk factors.

Dr.Thalheim says that while there isnt anything definitive that will prevent the development of bladder cancer, owners can limit exposure to herbicides and insecticides. She also points to a study that found a link between feeding vegetables three times a week and reduced bladder cancer risk in certain breeds, although owners should be careful to only feed safe vegetables to their dogs and to work with their veterinarian to come up with a dietary plan.

As for breeders, she recommends not breeding dogs diagnosed with TCC/UC and suggests that breeders ask buyers to let them know if their dogs present with TCC/UC later in life.

Dr. Arteaga says that she tells her clients that the same preventative measures human doctors tell patients also apply to dogs. Good exercise, low stress, no secondhand smoke, keeping weight down, and testing any masses that come up, as well as keeping up on a good dental routine may help prevent and catch problems early. She also advises owners and breeders to be diligent about chronic inflammation, like urinary tract infections, as chronic inflammation is a serious concern.

One of the best things owners of senior, at-risk breeds can do, however, is screen their dogs every four to sixmonths using the CADET Braf test.

What Are The Symptoms Of Bladder Cancer In Dogs

As demonstrated by Sallys story, the signs of bladder cancer and a UTI are often very similar. The symptoms might include:

  • Straining to urinate
  • Urinary accidents
  • Blood in the urine

In more advanced cases, a bladder tumor may cause a complete obstruction of the urethra so the dog is unable to urinate. The bladder may even rupture.

If the tumor has metastasized to the local lymph nodes, the vet might notice enlargement of the inguinal or sublumbar lymph nodes.

Although it is a rare occurrence, TCC can trigger hypertrophic osteopathy. This is a reaction of the periosteum leading to bone thickening and pain. It most commonly occurs in the lower portion of the legs.

What Do I Do To Allow My Dog To Participate

  • Case enrollment will be open starting in January 2022.
  • If you and your veterinarian would like for your dog to be evaluated for the trial, please ask your regular veterinarian to call the Purdue University Veterinary Hospital Oncology Service at -494-1107 to refer the dog for an appointment.
  • That visit will allow us to determine if the trial is the best option for your dog and if the dog is eligible. If we determine that the trial is not the best option, we can assist with other treatments too.
  • Thank you!

Cost Of Treatment For Transitional Cell Carcinoma

Canine Transitional Cell Carcinoma

As cost can be a limiting factor when deciding how to move forward, it is important to remember that none of the treatments for TCC are curative.

Surgery and radiation therapies are often expensive procedures, while chemotherapy can be a more affordable option.

Experimental options like bladder removal or synthetic bladders are also available.

A personalized treatment plan is important to slow the progression of TCC in your dog. Talk to your veterinarian about the best protocol for your pet.

Canine Clinical Trials A Win

Treatment studies in dogs are expected to be a winâwinâwin scenario . The individual dog receives treatment that is expected to help them and that often provides hope when other treatments are not effective or not feasible. The study results are expected to help other dogs and ultimately help humans with InvUC. The subsidized cost for treatment in many of the trials allows some pet owners to pursue treatment for their dog even if they cannot afford any other therapies. For all of these reasons, in the Purdue University Veterinary Teaching Hospital, more than 90% of owners of dogs with InvUC elect to enroll their pet in a clinical trial. Parallel mechanism studies are feasible in dogs with samples of blood, urine, and, in some cases, tumor tissues collected by cystoscopy available before, during, and after therapy. Most pet owners will also allow a necropsy of the dog when it dies or is euthanized . This provides crucial information on the disease process and response to therapy, and the opportunity to bank tissue samples for future studies. Although most treatments tested in dogs have been systemic therapies, dog studies can also be used to evaluate intravesical therapy .

How Long Can A Dog Live With Bladder Cancer

Being told that your dog has cancer is something that no pet owner ever wants to hear. It can be a terrifying and uncertain experience, with many questions that you need to ask and need answers for.

One of the most obvious ones, is wanting to know how your dog can survive with bladder cancer. Now, it will vary from dog to dog, but there are some generalizations you can make, so heres the short answer, followed by more detail.

How long can a dog live with bladder cancer? Some dogs can live for 6 to 12 months with bladder cancer. Providing it is diagnosed early enough, some dogs can benefit from cancer treatment, with their life expectancy sometimes being extended by a further 6 months.

Below Are Some Of The Treatments For Cancer In Dogs

Surgery With bladder cancer in dogs surgery may not always be an option but with other types it may be possible. Sometimes surgery may be performed to remove the tumor completely or to make it smaller so that it can be removed.

Chemotherapy This is when drugs are used to kill as many of the cancerous cells as possible. However, it is important that non-cancerous cells are not killed or left damaged. There are side effects of chemotherapy including sickness and nausea.

Radiation Radiation is when X-rays are used to treat cancerous tissues. Again, it is important that non-cancerous tissues are not damaged.

Cryotherapy This is when probes are used to freeze cancerous tissues. Normal tissue should not be damaged.

Hyperthermy Hyperthermy is used to treat cancer with heated probes heating the cancerous tissues to destroy them. It is not always possible to find veterinary surgeries that perform this type of surgical intervention.

Diet The diet is always very important in any dog or puppys health. Expert studies suggests that a diet that is free of simple sugars and does not have many moderate sugars is the most beneficialcancer diet. Easily digested proteins should also be limited to a moderate level. The diet should also include a set amount of fats if you are unsure then you should speak to your vet.

Conventional Treatment Of Canine Bladder Cancer

Transitional Cell Carcinoma in Dogs (TCC)

The conventional treatment of choice is chemotherapy.

A common chemotherapy plan is a combination of piroxicam with mitoxantrone. This combination can help in around 40% of dogs and the median survival time is about one year.

Another less aggressive chemotherapy plan is the use of only one drug . About 2 dogs in 10 will see improvement and the median survival time is about six months.

Surgery is usually difficult for bladder cancer in dogs because of two main reasons.

First, transitional cell carcinomas are locally aggressive and it is difficult to completely remove all cancer cells with surgery.

Second, the position of the tumor can make surgery difficult or even impossible, especially if the tumor occurs in the neck of the bladder where several vital structures are located.

Radiation may control the growth of the tumor but it has its limitation due to serious complications that can be caused by the treatment, such as a scarred, shrunken bladder, and irritation to surrounding organs.

Frequency And Clinical Presentation Of Invuc

Bladder cancer comprises ~1.5â2% of all naturally-occurring cancers in dogs, a rate similar to that reported in humans . With estimates that 4â6 million pet dogs develop cancer in the US each year, this equates to more than 60,000 cases of InvUC in dogs each year . It is acknowledged that many of these cases will go undiagnosed and untreated, but this still leaves large numbers of dogs diagnosed with InvUC who could participate in clinical trials.

The presenting clinical signs of InvUC are similar between dogs and humans, with hematuria being the most common change observed . Pain and urgency are not usually noted in the early stages of the cancer, but can emerge as the cancer progresses. A history of urinary tract infections is common in InvUC cases in humans and dogs. When cancer and infection are present concurrently, the clinical signs improve with antibiotic administration, but typically recur after the course of antibiotics is completed. As the cancer progresses, signs associated with metastases can emerge. Bone metastases, while uncommon, can lead to severe pain in both species.

The microscopic diagnosis of TCC is typically straightforward when adequate tissue is available for examination. Obtaining sufficient tissue samples by cystoscopy can be a challenge, and the operator must be diligent to collect enough tissue for diagnosis. In a report of 92 dogs, diagnostic samples were obtained by cystoscopy in 96% of female dogs and 65% of male dogs that ultimately had hisotopathologically diagnosed TCC . Placing tissue samples in a histology cassette before processing to prevent loss of small samples and using a wire stone collection basket to obtain larger pieces of tissue during cystoscopy has further improved the yield of diagnostic biopsy samples.

How Common Is Bladder Cancer In Dogs

Bladder Cancer in Dogs

As mentioned, bladder cancer in dogs is rare. In fact, it only comprises approximately 2% of all cancers in dogs. Invasive transitional cell carcinoma , is the most common cancer that affects the bladder.

An interesting thing to note is that although TCC can occur in any breed, this cancer more predominantly affects specific breeds such as Terriers and Beagles. Bladder cancer also tends to affect middle aged or elderly female dogs at higher rates.

Although there are less aggressive types of bladder cancer, dogs unfortunately rarely get this less aggressive form, meaning that this cancer is much more deadly if diagnosed.

Bladder Cancer In Dogs

The most common form of dog bladder cancer is a malignant cancer tumor called transitional cell carcinoma .

The tumor is developed from the cells lining the bladder . Therefore, such tumors are usually found in the inside lining of the bladder.

As the tumor grows, it takes over the space that is used for holding urine. As you can imagine, this obstructs the flow of urine from the kidneys to the outside of the body.

Canine transitional cell carcinoma is fairly aggressive. In one out of every 10 instances, it spreads to other sites of the body, such as the lungs, the bones, or the lymph nodes near the bladder.

Treatment Of Canine Transitional Cell Carcinoma

As with most tumors, the initial treatment for transitional cell carcinoma in dogs is wide surgical removal. However, the tumor is frequently found in an area that is difficult to excise or is more extensive than can be assessed clinically. Therefore, surgery rarely will cure dogs with TCC. A surgical debulking procedure may improve the survival time of dogs with TCC. This procedure will be explained with you if it is believed to be an option for your pet.

When wide surgical removal is not a viable option, radiation therapy can be used for local tumor control since we can often irradiate a larger area than a surgeon can remove. Radiation therapy has been used in humans for decades to control urinary tract tumors. At MedVet, we have frequently treated bladder and urethral tumors with radiation therapy when surgical removal is not possible. Both improvement in clinical symptoms and a decrease in tumor size are often observed in dogs treated with radiation therapy.

Nonsteroidal anti-inflammatory drugs have potential anti-cancer effects and have been shown to be beneficial for dogs with TCC. At this time, a combination of aggressive local control , chemotherapy, and NSAIDs is the recommended treatment for dogs with lower urinary tract tumors.

Dogs offer an exceptional opportunity to study potential genetic and environmental risk factors for TCC and to develop and test early detection and early intervention strategies. This is important because the causes of TCC in humans are only partially understood. Approximately half of TCC cases in humans are thought to be due to exposure to cigarette smoke and chemicals in the workplace . Exposure to herbicides, pesticides, and contaminants in agricultural chemical mixtures could also increase TCC risk, although not all studies support this role . Genetic factors in humans have been associated with increased TCC risk, especially in relation to chemical exposures, although the overall understanding of the heritable genetic variants associated with TCC risk in humans is minimal . More than half of people with TCC have no known environmental or genetic risk factors for the cancer . Studies are needed to further identify these factors and geneenvironment interactions that increase TCC risk, and dog studies could prove crucially important in this regard.

How Is Bladder Cancer In Dogs Treated

TCC is a difficult disease to treat surgically, but if the tumor is localized to a specific area, surgical removal with or without a tube cystostomy may be an option.

Most cases of TCC in dogs are treated with chemotherapy or radiation due to the nature and location of the tumor.

Some of the common chemotherapeutic agents used for treatment of TCC are:

  • Doxorubicin

These are often given in combination with nonsteroidal anti-inflammatories that also have some anti-TCC activity.

How Does Bladder Cancer Progress

Because transitional cell carcinomas are usually located at the neck of the bladder, urinary obstructions are common as the tumor progresses to the final stages. The tumor may block a ureter so urine from the kidney cannot enter the bladder. Or the tumor may block the urethra so that the patient cannot urinate.

A urinary obstruction can quickly become a life-threatening emergency. If at any point, you think your dog cannot urinate, please make an emergency vet visit immediately.

In other cases, the tumor causes so much inflammation and irritation that it affects the patients quality of life. Sadly, I euthanized one of my canine patients a few months after diagnosis because she felt like she had to urinate every twenty minutes. She was so uncomfortable that she wasnt able to sleep.

Some patients may also become sick because of metastatic spread of disease to other parts of the body. TCC can metastasize to lymph nodes, the lungs, bone, and prostate. In the final stages of metastatic bladder cancer, you may see pain, breathing problems, or swelling of limbs due to blockage of the lymphatic vessels.
