Canine Transmissible Venereal Tumor (CTVT) is a unique and contagious type of cancer that affects dogs. This article delves into what CTVT is, its transmission, symptoms, diagnosis, treatment, and prevention, providing a comprehensive overview for dog owners and veterinary professionals.
What is Canine Transmissible Venereal Tumor (CTVT)?
CTVT, also known as Sticker’s sarcoma, is a transmissible cancer that primarily affects the external genitalia of dogs but can also appear on other mucous membranes, such as the mouth, nose, and eyes. Unlike most cancers that arise from mutations within an individual’s cells, CTVT is spread by the transfer of living cancer cells from one dog to another. These cells take root and grow in the new host, making CTVT one of the few known naturally occurring transmissible cancers.
Transmission of CTVT
CTVT is transmitted through direct contact, typically during mating. The cancerous cells are transferred from an affected dog to a healthy dog via physical contact with the tumors. Other forms of contact, such as sniffing or licking the affected areas, can also lead to transmission. Because of its mode of transmission, CTVT is more commonly seen in stray or free-roaming dogs with uncontrolled breeding.
Symptoms of CTVT
The symptoms of CTVT can vary depending on the tumor’s location but generally include:
- Genital Tumors: Raised, cauliflower-like masses on the penis, vulva, or other genital areas. These tumors may bleed or ulcerate.
- Oral Tumors: Masses in the mouth or around the lips, leading to drooling, difficulty eating, and bad breath.
- Nasal Tumors: Tumors in the nasal cavity can cause sneezing, nasal discharge, and nosebleeds.
- Eye Tumors: Tumors around the eyes can cause swelling, discharge, and impaired vision.
Diagnosis of CTVT
Diagnosing CTVT involves a combination of physical examination and laboratory tests:
- Examen físico: A veterinarian will examine the dog’s external genitalia and other affected areas for characteristic tumors.
- Citología: A sample of cells from the tumor is examined under a microscope to identify the presence of CTVT cells.
- Biopsia: A tissue sample may be taken and analyzed to confirm the diagnosis.
Treatment of CTVT
CTVT is generally responsive to treatment, and several options are available:
- Quimioterapia: Vincristine sulfate is the most commonly used chemotherapy drug for treating CTVT. It is highly effective, with most dogs achieving complete remission after several treatments.
- Cirugía: Surgical removal of the tumors can be an option, especially if the tumors are small and localized. However, surgery alone may not be sufficient if the cancer has spread.
- Radioterapia: In cases where chemotherapy is not effective or feasible, radiation therapy can be used to target and destroy the cancerous cells.
Prevention of CTVT
Preventing CTVT primarily involves responsible pet ownership and control measures:
- Spaying and Neutering: Spaying and neutering dogs can reduce the risk of transmission through mating.
- Revisiones veterinarias periódicas: Regular health check-ups can help detect any abnormalities early and prevent the spread of CTVT.
- Controlling Free-Roaming Dogs: Reducing the population of stray dogs through community programs can help control the spread of CTVT.
Conclusión
Canine Transmissible Venereal Tumor (CTVT) is a unique and contagious cancer that primarily affects dogs’ genital areas but can also appear on other mucous membranes. Understanding the symptoms, transmission, and treatment options for CTVT is crucial for dog owners and veterinarians. With proper diagnosis and treatment, most dogs with CTVT can achieve complete remission and lead healthy lives. Responsible pet ownership and community control measures play a vital role in preventing the spread of this transmissible cancer.

Mast cell tumors (MCTs) are a common yet complex type of skin cancer in dogs. While they can range from benign to highly aggressive, understanding what causes these tumors is crucial for pet owners and veterinarians alike. This article delves into the causes, risk factors, and insights into mast cell tumors in dogs, providing a comprehensive overview for American pet owners.
The Role of Mast Cells in Canine Health
Mast cells are an integral part of the canine immune system, primarily involved in allergic reactions and inflammatory responses. They contain granules rich in histamine, heparin, and other chemicals that help the body respond to injuries and infections. However, when these cells undergo abnormal growth and proliferation, they can form tumors.
Causes of Mast Cell Tumors in Dogs
The exact cause of mast cell tumors in dogs remains unknown, but several factors are believed to contribute to their development:
- Genetic Predisposition: Certain breeds are more prone to developing mast cell tumors, indicating a genetic component. Breeds such as Boxers, Bulldogs, Boston Terriers, and Labrador Retrievers have a higher incidence of MCTs. The genetic mutations that predispose these breeds to MCTs are still under study, but they play a significant role.
- Factores ambientales: Exposure to environmental carcinogens, such as pesticides, herbicides, and certain chemicals, has been linked to an increased risk of developing mast cell tumors. Dogs living in urban or industrial areas might be at higher risk due to increased exposure to these substances.
- Chronic Inflammation: Chronic inflammation or irritation of the skin may contribute to the development of mast cell tumors. Persistent skin allergies or infections can lead to an increased number of mast cells in the affected area, raising the risk of tumor formation.
- Immune System Dysregulation: Abnormalities in the immune system, including autoimmune diseases, can predispose dogs to mast cell tumors. An overactive or malfunctioning immune system might trigger the uncontrolled growth of mast cells.
Risk Factors for Mast Cell Tumors
While the exact causes are still being investigated, several risk factors have been identified:
- Edad: Older dogs are more susceptible to developing mast cell tumors, although they can occur at any age.
- Raza: As mentioned, certain breeds are genetically predisposed to MCTs.
- Skin Conditions: Dogs with a history of chronic skin conditions or allergies are at a higher risk.
- Previous Tumors: Dogs that have had mast cell tumors before are at an increased risk of developing them again.
Understanding the Behavior of Mast Cell Tumors
Mast cell tumors can vary significantly in their behavior and severity. They are generally classified into three grades based on their appearance under a microscope and their potential for metastasis:
- Grade I (Low-grade): These tumors are usually well-differentiated, less aggressive, and have a lower risk of spreading. They often respond well to surgical removal.
- Grade II (Intermediate-grade): These tumors have a moderate risk of spreading and may require a combination of surgery, chemotherapy, or radiation therapy.
- Grade III (High-grade): These are poorly differentiated, highly aggressive tumors with a high potential for metastasis. They often require aggressive treatment and have a poorer prognosis.
Diagnóstico y tratamiento
Accurate diagnosis of mast cell tumors involves a combination of clinical examination, fine-needle aspiration, biopsy, and imaging techniques such as X-rays and ultrasounds. Treatment options depend on the grade and stage of the tumor and may include:
- Extirpación quirúrgica: The primary treatment for localized mast cell tumors. Wide surgical margins are often recommended to ensure complete removal.
- Quimioterapia: Used for high-grade tumors or those that have spread to other parts of the body.
- Radioterapia: Effective for tumors in locations where surgery is not feasible or as an adjunct to surgery.
- Terapia dirigida: Newer treatments that target specific genetic mutations associated with mast cell tumors.
Preventive Measures and Monitoring
While it’s challenging to prevent mast cell tumors entirely, regular veterinary check-ups and early detection can significantly improve outcomes. Pet owners should monitor their dogs for any unusual lumps or skin changes and seek veterinary advice promptly.
