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.
Signs of bladder problems: Unfortunately, chemotherapy for lymphoma is very unlikely to cure your pet, but will allow a good quality of life to be enjoyed for some time.
Inevitably, the cancer cells become resistant to the drugs we use, and the cancer will come back. Eventually, the tumour cells will become resistant again and it is likely that your pet will have to be put to sleep when his or her quality of life deteriorates. Hopefully, this will be after many happy months of good quality life for your pet and you to enjoy together. Why should I bring my dog to Willows for diagnosis and management of lymphoma?

Cutaneous lymphoma may progress slowly and often has been treated for several months as an infection or allergy before a diagnosis of lymphoma is made.
Cutaneous lymphoma may also appear in the mouth, often affecting the gums, lips, and the roof of the mouth. Cutaneous lymphoma in the mouth is often mistaken for periodontal disease or gingivitis in its early stages. The photo on the left shows cutaneous lymphoma in the mouth of a dog. Note the very red gums and the ulceration on the roof of the mouth.
Dogs with gastrointestinal lymphoma usually have symptoms such as vomiting, watery diarrhea, and weight loss. The diarrhea is often very dark in color and foulsmelling. Dogs with mediastinal lymphoma typically have difficulty breathing. This may be due to the presence of a large mass within the chest or due to the accumulation of fluid within the chest pleural effusion. Affected dogs may also show swelling of the face or front legs as well as increased thirst and urination.
The best way to diagnose lymphoma is to perform a biopsy. A biopsy is a minor surgical procedure to remove a piece of lymph node or other organ affected by cancer. The most common methods for lymph node biopsy are Tru-cut needle biopsy, incisional wedge biopsy, or removal of an entire lymph node excisional biopsy.
The larger the biopsy sample, the better the chance for an accurate diagnosis of lymphoma. Dogs are placed under heavy sedation or general anesthesia to perform a biopsy. Although discomfort associated with this procedure is typically minimal, we often prescribe oral pain medication afterwards just to be sure your dog is comfortable following the biopsy.
In addition to biopsy, we recommend several staging tests for dogs with lymphoma. However, dogs with very advanced lymphoma can still be treated and experience cancer remission see more on treatment below. Staging tests also help us assess whether your dog has any other conditions that may affect treatment decisions or overall prognosis. Organs that appear abnormal on sonogram can be sampled with a small needle fine needle aspirate to confirm the presence of lymphoma.
The most effective therapy for most types of canine lymphoma is chemotherapy. In some cases, surgery or radiation therapy may also be recommended. There are numerous chemotherapy treatment protocols for dogs with multicentric lymphoma. As discussed below, most dogs with lymphoma experience remission of their cancer following treatment, and side effects are usually not severe. Currently, the protocols that achieve the highest rates of remission and longest overall survival times involve combinations of drugs given over several weeks to months.
It is based on a protocol called CHOP that is commonly used to treat lymphoma in humans. The UW protocol may not be appropriate for all dogs with lymphoma.
Different types of lymphoma may be treated with different chemotherapy drugs. For instance, the most effective drug for cutaneous lymphoma is thought to be lomustine CCNU. The veterinary oncologists and oncology residents at the PUVTH will help you decide on a chemotherapy treatment protocol that is appropriate for your dog. Even though cancers may be slow growing, they can sometimes cause sudden signs of illness.
Usually it is not possible for the vet to tell whether an animal has cancer just by looking. Blood tests to screen for cancer are still in their infancy. Further tests, such as blood samples and x-rays, are often needed. Ultrasound or MRI scanning may be suggested.
A biopsy taking a small sample for examination under a microscope may help to identify the tumour and see if it is cancerous. Reaching a definite diagnosis can sometimes be difficult; for example, biopsies do not always contain enough good quality material when examined under a microscope.
There are many types of tumours and treatment is available for non-cancerous and even for some cancerous tumours. For an isolated lump that has not spread within the body, surgery may provide a cure. But it does depend on where the tumour is growing. Even a benign tumour in an area such as the brain cannot be easily removed in animals.
Where a cancer is spreading inwards, the possibilities for treatment depend on the exact type of cancer and how far it has spread. However, quality of life is important and if an animal is in severe, unrelievable pain, your vet is likely to encourage you to choose euthanasia. There are three basic types of treatment — surgery, chemotherapy and radiotherapy. Several other new therapies are also sometimes available, such as photodynamic therapy or immunotherapy.
Some forms of treatment require frequent visits to your own vet, or to specialists, and it can be important for treatment to be given at particular time intervals.
Surgery is often chosen for tumours of the skin, or for internal growths that are apparently distinct. The lump removed at surgery usually needs to be analysed to find out whether or not it is likely to have spread.
Sometimes with internal growths where the size of the tumour is causing illness, surgery can relieve the symptoms but the risk of recurrence remains. Chemotherapy is appropriate for several types of cancer.
Veterinary chemotherapy usually has few side effects, or none at all, because the doses used are smaller than those used in humans. Unfortunately, it does not usually cure the cancer — the aim is to slow the cancer down and reduce the symptoms. Chemotherapy is sometimes carried out following surgery, if it has not been possible to remove the entire cancer, to try to slow down recurrence.
It is also used in widespread cancers that cannot be surgically removed, such as those involving the white blood cells leukaemias. Some types of chemotherapy may be available from your own vet; others are only carried out by specialists. Regular visits to the vet for treatment are usually essential and sedation may be needed during treatment. You may need to give tablets as well.
