What Is The Prognosis For Pets With Lymphoma
The goal of chemotherapy is to induce a remission in your pets cancer. Remission means regression of the cancer. Remission may be partial, indicating the overall cancer burden has been reduced by at least 50%, or complete, which means the cancer is no longer detectable by physical examination or standard screening tests. Without treatment, dogs and cats with lymphoma in multiple organs live an average of 6 weeks. However, this varies with the type and extent of lymphoma. The average lifespan for dogs with B-cell lymphoma treated with multi-drug chemotherapy is 1 year, with approximately 25% living 2 years or longer. Dogs with T-cell lymphoma generally do not respond to treatment as well and their average survival time is 6-10 months. In the cat, median survival time with treatment is 7-9 months however, if a complete response is achieved the expected lifespan may be significantly increased. It is important to remember that these are average survival times and some pets will live much longer , whereas others, unfortunately, have resistant cancers and respond for shorter periods of time or do not respond at all.
Miscellaneous Lymphoma Types In Cats
There are also less common forms of lymphoma affecting the nerves, the lymph nodes, or other sites in the body. Multi-nodal lymphoma/multicentric lymphoma, cutaneous lymphoma, mesenteric lymphoma, ocular lymphoma, and spinal lymphoma are all other types of lymphoma in cats. There is some evidence that cutaneous lymphoma in cats is becoming more common.
How Long Can Cats Live With Lung Cancer
Unfortunately, average lung cancer survival time is less than six months, although it can be over a year if the tumour is detected before it metastasizes. The prognosis is worse with lung-digit syndrome, with survival time averaging just a couple of months. Cats are usually euthanized due to their metastatic disease.

How To Diagnose Lymphoma In Cats
To diagnose lymphoma, your veterinarian will need to take a detailed medical history and complete a series of tests. A bone marrow biopsy can confirm the diagnosis conclusively, but your furry friend may first undergo a blood test, biochemistry profile, urinalysis, and X-rays. If your veterinarian suspects the liver or spleen is affected, your kitty may need an ultrasound. Many cats are also tested for FeVL at this time. Identifying the origin and stage of your cats lymphoma is essential to developing the best treatment plan so that you may be referred to a veterinary oncologist.
How Is Lymphoma Diagnosed
Diagnosing lymphoma requires finding cancerous cells on microscopic examination. Your veterinarian also may perform baseline screening bloodwork before testing for lymphoma, in order to assess your cats overall health and rule out other causes of your cats clinical signs.
In some cases, feline lymphoma can be diagnosed with a fine needle aspirate. In this test, a veterinarian will insert a needle into an area of concern and remove a small number of cells. These cells will then be examined under a microscope, looking for cancer cells that indicate lymphoma. Although it is not always possible to obtain a high-quality diagnostic sample via aspirate, many veterinarians start with this test because it carries minimal risks, side effects, and costs compared to surgical biopsy.
“In some cases, feline lymphoma can be diagnosed with a fine needle aspirate.”
If a fine needle aspirate is inconclusive, or is impractical due to the location of the lesion, your veterinarian may instead perform a surgical biopsy. This involves the removal of a piece of tissue from the lesion. In cases of suspected gastrointestinal lymphoma, this sample may be obtained surgically or endoscopically . Regardless of collection technique, this sample will be processed and examined under a microscope to assess for lymphoma.

If Ignored Or Left Untreated
If ignored, or left untreated, Canine Lymphoma will grow quickly, and can generally kill a dog within 1 to 3 months after initial detection.
But with appropriate treatment, many dogs will experience remission from the disease for an extended period of time . For that reason, the primary goal of modern conventional Canine Lymphoma treatments is not to cure the patient, but to help the patient to go into remission for as long of a period as possible.
Note: Remission is the term vets use to mean that they are unable to detect any physical evidence of the existence of the cancer in the patient. In other words, patients in remission show no symptoms of the disease, and their cancer is clinically non-detectable through physical examination and other available tests. In truth though, despite the fact that dogs in remission seem perfectly healthy, and tests cant identify the disease, vets assume that in the vast majority of patients the cancer is still there, just small and hidden away to the extent that present tests are unable to detect its presence.
Feline Lymphoma: What Your Need To Know
November is National Pet Cancer Awareness Month. Last spring I wrote about canine lymphoma, so in honor of Cancer Awareness Month, I thought I would do the same for feline lymphoma.
What is Lymphoma?
Lymphoma is cancer of the immune system. The immune system is distributed throughout the body to protect against infections. Lymphoma in cats most commonly affects the gastrointestinal tract, although since the immune system is distributed throughout the body, lymphoma can be seen in any organ in the body including the eyes, in front of the heart, and in the kidneys, liver or spleen. Unlike canine lymphoma, feline lymphoma rarely occurs in the lymph nodes.
In cats it is not a single disease, but is probably more than 20 different diseases each of the 20 or so forms of lymphoma behaves somewhat differently and the prognosis varies between types. The most common form of lymphoma we see in cat intestines is called small cell lymphoma. We also see an intestinal variant called large cell lymphoma. The photomicrograph on the right shows a rare form of feline lymphoma called large granular lymphoma. The name comes from the granules seen in some of the cancerous lymphocytes.

Multiple Lymphoma Protocols
In my office file drawers, I have a big fat folder of articles describing various chemotherapy protocols for the treatment of lymphoma. Many of them are simply a riff on a theme. In my opinion, there are three basic options for chemotherapy of feline lymphoma:

How Long Can Cats Live With Lymphoma
. Considering this, how long can a cat live with untreated lymphoma?
The response from steroids is difficult to predict with some cats‘ lymphoma not responding while other cats can live as long as 6 months with steroids alone. Because lymphoma tends to be a quickly progressive cancer, if left untreated the expected survival time is approximately 4-6 weeks.
Additionally, how long do cats live after being diagnosed with cancer? Untreated, the average survival time from diagnosis is about two months. This can be prolonged with chemotherapy , although unfortunately not all lymphomas respond, especially if the cat has feline leukaemia virus.
Just so, is lymphoma in cats painful?
Unfortunately, there are no particularly striking symptoms of this illness. “Because gastrointestinal lymphoma is the most common form of this cancer, symptoms you might see in your cat are quite general and include weight loss, vomiting, diarrhea and loss of appetite,” says Dr.
Is Cancer painful for cats?
While each type of cancer has its own distinctive symptoms, most indicate their presence by the occurrence and the prolonged presence of any common symptom. Some of the general symptoms of cancer in cats are: Any lump that changes shape or size. Any sore that does not heal.
The Word Chemotherapy Sounds Scary And I Do Not Think I Want To Go Down This Path What Now
That is a common initial response from pet owners when they hear the word ‘chemotherapy’. However, chemotherapy in pets is much different to people. It is essential to understand the difference between chemotherapy treatment in human and veterinary medicine. In human medicine, the main objective of chemotherapy is to eliminate all cancer cells to try to obtain a cure. Usually, it is administered aggressively and has more chances of developing side effects. Curing cancer in veterinary medicine is desirable . However, due to the less aggressive approach , pets usually tolerate chemotherapy far better than humans. The primary goals of chemotherapy are to minimise discomfort associated with cancer growth or slow the progression of cancer while striving to maintain or improve the pet’s quality of life.
Pets experience fewer and less severe side effects than humans. Approximately 90% of cats that receive chemotherapy experience no side effects. About 10% of cats experience a chemotherapy side effect , which can often be managed with supportive home medications. Approximately 5% of pets experience a chemotherapy side effect that requires hospitalisation. For example, when the neutrophil count drop to a critically low value and cats experience sepsis or infection. Less than 1% of chemotherapy side effects unexpectedly results in death. Occasionally cats will require dose reductions or treatment breaks in order to tolerate chemotherapy.

Forms Of Extraintestinal Lymphoma
Common forms of extraintestinal lymphoma include nasal, mediastinal, nodal, and renal, as well as laryngeal, CNS, and cutaneous.
Clinical presentation, diagnosis, and treatment of extraintestinal lymphomas depends on the site of involvement and extent of disease, though there are many commonalities. Most lymphomas that occur outside of the intestinal tract are considered large cell, typically causing acute symptoms and rapid progression without treatment.
In addition to tumor diagnosis, staging is often recommended and typically includes a complete blood count, serum chemistry profile, urinalysis, FeLV/FIV testing, thoracic and abdominal imaging , and sometimes advanced imaging or bone marrow aspiration. Using a well-established reference laboratory that offers diagnostic testing, imaging and pathology consulting services allows for cohesive review of all the patient information.
Cats with nasal lymphoma generally present with symptoms of nasal discharge, facial deformity, and/or sneezing. Advanced imaging, often with CT scan, is necessary to assess the extent of disease and plan treatment, and whole-body staging is necessary to confirm the disease is confined to the nose.
How Can Lymphoma In Cats Be Treated
Your vet will most likely recommend chemotherapy for treatment of feline lymphoma. With small cell lymphoma in cats, treatment often includes oral chemotherapy options.
In addition to mainstream treatment options, there are natural products for lymphoma in cats as well. Here at HomeoAnimal, we have made it our mission to provide natural products for pets.

The Different Types Of Feline Lymphoma
One of the most common forms of lymphoma in cats is intestinal lymphoma. In this condition, the intestines become infiltrated with cancerous lymphatic cells. Poor appetite, weight loss, vomiting, and diarrhea may occur. The intestines may become palpably thickened. In some instances, lymph nodes adjacent to the intestines will become markedly enlarged, leading to an intra-abdominal mass that can be palpated by veterinarians.
There are several different types of intestinal lymphoma, and they vary in their aggressiveness. However, one of the most common types appears to occur as a complication of inflammatory bowel disease. This type of lymphoma generally is relatively slowly progressive it therefore carries a better prognosis than many other types of cancer.
Because the immune system exists almost everywhere in the body, lymphoma can occur in just about any organ. Cats may experience lymphoma of the nose, which can cause sinus congestion, nasal discharge, sneezing, and difficulty breathing. Lymphoma can occur in the chest, causing coughing and labored breath. Lymphoma can infiltrate the eyes, compromising vision. Lymphoma can occur in the kidneys, causing kidney failure . Lymphoma has been documented to occur in the skin, causing rashes and other cutaneous irregularities.

What Is Remission Vs Cure
For your understanding remission means that the cancer is no longer detectible by tests available to your vet. In those cases your dog should show little or no signs of the disease, and enjoy a normal life throughout the entire period of the remission. However, while the cancer is not detectable during these times of remission, a few undetected cancer cells may remain, and the main problem causing the cells to become cancerous in the first place may remain, which is why in most cases the cancer will likely return at the end of some remission period.
The distinction between remission and cure with regards to Canine Lymphoma life expectancy, is the complete elimination of the canine lymphoma cells and while cases of complete cure are much less common using conventional treatment methods, remission is available in most of the canine lymphoma cases we see.
Diagnosis And Initial Evaluation
A biopsy or cytology sample is required in order to make a diagnosis of lymphoma. In some cases, we can obtain a diagnosis by a fine needle aspirate, but in other situations, a biopsy to obtain a larger piece of tissue is necessary to confirm the diagnosis. The ease with which a diagnosis can be obtained depends upon where the tumor is located.
The first step for any patient suspected of having lymphoma includes determining the extent of the disease which is known as staging. This includes a complete blood count , serum chemistry profile , urinalysis and FeLV/FIV testing are always recommended and provide important information regarding the effects of the cancer on body functions as well as the ability of the patient to handle chemotherapy or other treatments. Additional tests include chest radiographs, abdominal ultrasound along with possible bone marrow aspirate and CT/MRI. Once we determine the extent of disease, we can then decide on the best treatment for your pet.

Causes Of Lung Cancer In Cats
The exact causes of lung cancer in cats are poorly-understood. Its suggested that retroviruses and exposure to environmental tobacco smoke may be risk factors, but we dont know anything definitive.
The causes of lung cancer in cats are poorly understood. We know that the number of cases is increasing, but it isnt clear if this is due to longer life expectancy, better awareness, increased funds for investigation, better imaging techniques, genetics, or exposure to a higher number of carcinogens. Its likely its a combination of factors.
One suggestion is that retroviruses such as FeLV and FIV may have some impact on a cats lung cancer risk. Some lung cancers in other species are spread by retroviruses, and we know that FeLV increases the risk of lymphoma. However, theres no evidence that this is the case for primary lung tumours in cats at present.

As in people, its possible that exposure to cigarette smoke could be a risk factor for lung tumours in cats. Although there is currently no direct evidence for this, we know that passive smoke inhalation increases the risk of some oral tumours in cats, and that passive smoking increases the risk of lung tumours in humans and dogs.
In fact, in some ways, cats are in more danger from second-hand smoke- they can ingest the toxins when grooming.
Lymphoma In Cats Treatment
Feline lymphoma can be treated with surgery, chemotherapy, or radiotherapy, depending on the type, grade, and location of the cancer. The difficulty with treating lymphoma in cats is that the cancerous cells are generally spread over a large area, so its not as simple as just cutting them out.
Chemotherapy is the most common lymphoma treatment plan in cats, as it can help to kill all cancer cells including those not in the main location of the tumour. Chemotherapy for low-grade lymphoma usually involves tablets, whilst high grade lymphoma is more likely to require injectable chemotherapy.
Cats tolerate chemotherapy very well and dont suffer too badly with side effects- they rarely lose their hair or appear sick, but some will get mild vomiting or diarrhea. Oral chemotherapy with prednisone and chlorambucil is suitable for small cell lymphoma, but the more aggressive types of lymphoma need a more intense treatment including injectable chemotherapy drugs. This chemotherapy protocol is commonly called a CHOP protocol and includes cyclophosphamide, doxorubicin, prednisolone, and vincristine.
There are several options for treatment of lymphoma in cats, with treatment routes varying in aggressiveness and which type of lymphoma they address.
We have listed the most common type of therapy pursued and the average survival times below:
