Endometrial Carcinoma (Uterine Cancer) in Dogs

Occurrence: common
Location of illness: Abdomen/pelvis

Endometrial carcinoma, also known as uterine cancer, is a malignant tumor disease that originates from the lining of the uterus (endometrium) in dogs. It is a rare disease, but when it occurs, it can have serious health consequences for the affected animals.

The most important facts at a glance

Endometrial Carcinoma in dogs is a cancer that affects the inner lining of the uterus and is favored by hormonal influences such as an imbalance of estrogen and progesterone. Genetic and environmental factors may also play a role. Symptoms include vaginal discharge, Infertility, loss of appetite, and Weight loss. Diagnosis is made through clinical examinations and imaging procedures such as ultrasound. A biopsy is often necessary to confirm cancer cells.

Treatment usually involves surgical removal of the uterus, while advanced cases may also require chemotherapy or radiation therapy. The prognosis depends on the stage of the disease; early removal improves the outlook. Preventive measures such as spaying can reduce the risk as they eliminate hormonal cycles. Regular veterinary examinations are important to detect health problems early.

Research is underway to better understand the causes and improve diagnosis. Genetic studies and the search for biomarkers are promising. New therapeutic approaches and drugs are also being developed to improve the quality of life of dogs. The research aims to significantly improve the diagnosis and treatment options in the future.

Causes

In dogs, the endometrium is the inner layer of the uterus, which plays a crucial role in the reproductive system. The cells of the endometrium are hormonally active and respond to the cyclical changes in hormone levels that occur during the reproductive cycle. These hormonal fluctuations can lead to cell proliferation, which is normally regulated. However, in some dogs, errors can occur in this process, which can lead to the development of Tumors.

The exact cause of Endometrial Carcinoma in dogs is not fully understood. However, it is believed that hormonal influences play a significant role. Similar to humans, an imbalance of estrogen and progesterone can increase the risk of developing Tumors in the endometrium. Some studies suggest that dogs that are not spayed and are therefore exposed to cyclical hormonal influences may be at higher risk.

Genetic factors may also play a role. Certain breeds may be more susceptible to developing this type of cancer due to genetic predisposition. Other factors such as environmental toxins, diet, and pre-existing conditions of the reproductive tract may also increase the risk, but are less well researched.

Symptoms

Very common symptoms:

Common symptoms:

The symptoms of Endometrial Carcinoma in dogs can vary and are often non-specific, which can make diagnosis difficult. A common sign is vaginal discharge, which may be bloody or purulent. However, this symptom can also occur with other diseases of the reproductive tract.

Other symptoms may include Abdominal pain or discomfort, Weight loss, loss of appetite, and general lethargy. In advanced stages, there may also be noticeable Swelling of the abdomen, caused by enlargement of the uterus or fluid accumulation.

Because these symptoms can also occur with other diseases, it is important that affected dogs be examined by a veterinarian to make an accurate diagnosis.

Diagnosis

The diagnosis of Endometrial Carcinoma in dogs requires a thorough clinical examination combined with various diagnostic tests. The veterinarian will first take a complete history and perform a physical examination to identify obvious signs of the disease.

Imaging procedures such as ultrasound and X-rays are crucial to assess the uterus and detect possible Tumors or enlargements. An ultrasound can help visualize the structure and thickness of the endometrium and identify abnormalities.

However, a definitive diagnosis often requires a biopsy of the endometrium. This can be done by surgical removal or a less invasive method such as an endoscopic examination. The tissue samples obtained are then examined histopathologically to confirm the presence of cancer cells.

Therapy

The treatment of Endometrial Carcinoma in dogs depends on the severity and stage of the disease. In many cases, surgical intervention is necessary to remove the affected uterus. This operation, known as ovariohysterectomy, involves the removal of the ovaries and uterus and is often the preferred treatment method.

For dogs in advanced stages or those in whom the cancer has metastasized, adjunctive treatments such as chemotherapy or radiation therapy may be considered. However, the effectiveness of these treatments in dogs is limited, and they are mostly used to relieve symptoms and prolong survival time.

Close follow-up care is crucial to monitor the response to treatment and detect possible relapses early. The veterinarian will order regular check-ups and closely monitor the dog’s health.

Prognosis and follow-up care

The prognosis for dogs with Endometrial Carcinoma depends on several factors, including the stage of the disease at the time of diagnosis and the treatment chosen. In the early stages, complete surgical removal of the uterus can offer a good prognosis, especially if the cancer has not yet metastasized.

In advanced stages or when the cancer has spread to other organs, the prognosis is often worse. Life expectancy can be significantly shortened in such cases, although treatment can help improve the dog’s quality of life and relieve symptoms.

Regular follow-up examinations are crucial to monitor the progression of the disease and make adjustments to the treatment if necessary.

Prevention

Since the exact causes of Endometrial Carcinoma in dogs are not fully understood, there is no guaranteed method to prevent this disease. However, some measures can help reduce the risk.

Spaying female dogs can significantly reduce the risk of uterine cancer, as it eliminates the hormonal cycles that can contribute to tumor formation. This measure is especially important in dogs that are not intended for breeding.

A healthy diet and a healthy living environment can also help reduce the overall risk of cancer. Regular veterinary check-ups are crucial to detect and treat health problems early.

Further research is needed to better understand the exact causes and risk factors for Endometrial Carcinoma in dogs and to develop more effective prevention strategies.

Outlook on current research

Research on Endometrial Carcinoma in dogs is still in a relatively early stage compared to research on other types of cancer in pets. Nevertheless, there is progress, especially in the area of diagnostic procedures and the genetic basis of the disease. Researchers are working to identify specific biomarkers that can help detect Endometrial Carcinoma early. These biomarkers could provide clues at the molecular level about the presence of cancer cells before they become clinically visible.

Another area of current research is the investigation of genetic predisposition in different dog breeds. There is evidence that certain breeds may be more susceptible to Endometrial Carcinoma. Identifying genetic factors that increase the risk could allow veterinarians to recommend preventive measures or intensify monitoring in at-risk dogs.

Therapeutic approaches are also being intensively researched. Currently, various treatment methods such as surgery, chemotherapy, and radiation therapy are being investigated. The combination of these methods could potentially improve the prognosis. In addition, new drugs are being developed that specifically target the cancer cells without damaging healthy tissue. These targeted therapies could enable personalized treatment for affected dogs in the future.

Another important aspect of research is improving the quality of life of dogs suffering from Endometrial Carcinoma. Studies are investigating how pain management and supportive therapies can be optimized to ensure the well-being of the animals. The role of nutrition and general health is also being investigated in this context.

In conclusion, research on Endometrial Carcinoma in dogs is on a promising path. By combining genetic research, innovative treatment methods, and a better understanding of the disease, scientists hope to significantly improve diagnosis and treatment in the years to come.
