Most chemotherapy drugs are given by intravenous IV injection, although a few are given by mouth as a tablet or capsule. Patients are usually dropped off at 9: Most dogs tolerate chemotherapy well, much better than humans typically do. Although some dogs do get sick from chemotherapy, serious side effects are uncommon. The most common side effects include loss of appetite, decreased activity level, and mild vomiting or diarrhea that persists for one or two days.
If serious or unacceptable side effects do occur, it is important that you talk to one of our oncology doctors or staff about this. We can recommend symptomatic treatment to lessen the side effects of chemotherapy. In addition we may recommend reducing the dose of chemotherapy the next time it is to be given. Unlike people, dogs usually do not lose their hair when treated with chemotherapy. The exceptions to this rule are poodles, Old English sheepdogs, and some terriers — these breeds may lose their hair while receiving chemotherapy.
Hair growth should resume once chemotherapy is discontinued. In rare instances, dogs are apparently cured of their lymphoma by chemotherapy. Unfortunately, most dogs with lymphoma will have relapse of their cancer at some point.
A second remission can be achieved in a large number of dogs, but it is usually of shorter duration than the first remission. This is because the lymphoma cells become more resistant to the effects of chemotherapy as time goes on.
Eventually, most lymphomas develop resistance to all chemotherapy drugs, and dogs with lymphoma die or are euthanized when the cancer can no longer be controlled with chemotherapy. The median length of survival of dogs with multicentric lymphoma treated with UW chemotherapy is between months. We are currently conducting multiple clinical trials for dogs with lymphoma at Purdue.
Varying degrees of financial support are available to owners who agree to allow their dogs participate in these clinical trials. To determine whether your dog may qualify for a clinical trial, please ask your dog's primary care veterinarian to call and ask to speak with a member of our Canine Lymphoma clinical trials team, or you may contact our Canine Lymphoma Clinical Trials Coordinator, Ms. If you have trouble accessing this page because of a disability, please contact PVM Web Communications at vetwebteam purdue.
College of Veterinary Medicine. Purdue Comparative Oncology Program. Canine Lymphomas Canine lymphomas are a diverse group of cancers, and are among the most common cancers diagnosed in dogs. What causes lymphoma in dogs? What are the most common symptoms of canine lymphoma? How is canine lymphoma diagnosed? Are any other diagnostic tests required for dogs with lymphoma?
How is canine lymphoma treated? What does remission mean? Lymphoma is a form of cancer in dogs that affects the lymphocytes , which are white blood cells that are important for immune system function. It is one of the most common malignant tumors in canines, and is usually found in the lymph nodes, the spleen, or the bone marrow, which is where lymphocytes are most concentrated, though it can appear in any organ of the body. Lymphoma can be deadly for dogs if left untreated. Here is what you should know about the types, causes, symptoms, and treatments for lymphoma.
There are four types of lymphoma, however, that are most common. Lymphoma is also designated by stage based on how it has metastasized and how invasive it is. The stages are as follows. The exact causes of lymphoma in dogs are unknown, but there are certain factors that put dogs more at risk for developing the condition.
Dogs with compromised immune systems are more prone to developing lymphoma. Dogs that are exposed to herbicides and those that live in industrial areas are also at greater risk. Chemotherapy can be restarted when a patient relapses i. Patients are individuals, so the response varies from case to case, and because of this, all patients receiving chemotherapy are carefully monitored and protocols adjusted to suit the individual. What are the potential side effects of chemotherapy and how can they be minimised?
Side effects can be seen because chemotherapy agents damage both cancer and normal rapidly dividing cells. Normal tissues that are typically affected include the cells of the intestine, bone marrow which makes the red blood cells, white blood cells and cell fragments involved in blood clotting called platelets and hair follicles.
Hair loss is uncommon in dogs having chemotherapy, but it can be seen in certain breeds that have a continuously growing coat, such as Poodles and Old English Sheepdogs cats rarely develop hair loss, but may lose their whiskers. Hair usually grows back once chemotherapy is discontinued. Damage to the cells of the intestines can result in changes in appetite or stool consistency and occasionally vomiting.
Damage to the bone marrow reduces blood cell production, particularly infection fighting white blood cells neutrophils. Steroids are often used in combination with chemotherapy. These medications can make patients feel that they want to eat and drink more especially during the first week of therapy when doses are usually higher and given every day.
Patients should not have their access to drinking water restricted, but it is important not to increase their food intake, as excess weight gain can be problematic. The increased thirst is associated with increased urination, so patients may also need to go out to pass urine more often. Epirubicin , another chemotherapy agent, can cause damage to the heart muscle over time. The more doses your dog has, the greater the risk. For this reason, we will carry out checks on the heart before the drug is given for the first time and at various points during the treatment course.
Heart complications are extremely uncommon and your dog is at much greater risk if the lymphoma is not treated. We prescribe medications to help to prevent complications, and we will advise you on which signs to monitor. Compared to human patients who receive chemotherapy, pets experience fewer and less severe side effects, and these can usually be managed at home. This is because we use lower drug doses and do not combine as many drugs as in human medicine.
What precautions do I need to take at home, with my pet having chemotherapy? Signs of gastrointestinal upset: Also watch for any dark coloured faeces. Signs of bone marrow suppression: Neutrophils infection fighting white blood cells are at their lowest point usually 5 to 7 days after treatment. If your pet is depressed, off its food, panting excessively or is hot to the touch at this time, please contact us.
Lymphoma in animals
Lymphosarcoma (lymphoma) is the third most common cancer diagnosed in dogs. Lymphosarcoma can be divided up into 5 different forms which Dogs with this type of lymphosarcoma may have vomiting, diarrhea. What is lymphoma in dogs? Lymphoma is a cancer of the lymphatic system. This widespread involvement is not like tumour spread in other types of cancer. They collectively represent approximately % of all cancers diagnosed in dogs. There are over 30 described types of canine lymphoma, and these cancers .
