Soft Tissue Sarcoma in Dogs: Causes, Symptoms, and Treatment Options

Soft tissue sarcoma (STS) is a form of malignant cancer found in dogs, typically originating from mesenchymal cells. While this cancer can develop in various areas, it is most commonly located in the dog’s head, neck, and trunk regions. These firm, under-the-skin tumors may appear discrete but are often invasive, making local recurrence possible even after treatment.

What is Soft Tissue Sarcoma in Dogs?

Soft tissue sarcoma encompasses a variety of tumors that arise from the skin and subcutaneous connective tissue. It typically affects the muscle, fat, fibrous connective tissue, cartilage, small blood vessel pericytes, and nerves. Although STS tumors tend to be locally aggressive, their potential to metastasize to other parts of the body is relatively low, particularly in low to intermediate grades.

Early detection and treatment are crucial, as higher-grade tumors have a greater chance of spreading. Even though surgical and holistic treatments can be effective, regrowth is not uncommon due to the tumor’s invasive nature.

Symptoms of Soft Tissue Sarcoma in Dogs

• Firm lumps under the skin, often on the head, neck, or trunk
• Lumps that appear discrete but may grow over time
• Reduced mobility if tumors press on nearby muscles or joints
• Swelling and inflammation in the affected area

Treatment Options for Soft Tissue Sarcoma in Dogs

1. Remoção cirúrgica: Surgery is often the first line of defense, especially for localized tumors. However, due to the invasive nature of STS, regrowth in surrounding tissues is possible even after complete removal.
2. Holistic Treatments: Integrating traditional Chinese medicine (TCM) such as Scrophularia (for tumor management) and Szechuan lovage (for promoting blood circulation and reducing cysts) may support overall healing and tumor reduction.
3. Radioterapia: For tumors that are not easily removed surgically or as a follow-up to surgery to prevent regrowth.
4. Quimioterapia: While chemotherapy is less common for soft tissue sarcomas, it may be considered for high-grade tumors that have a higher risk of spreading.

Prognóstico e Prevenção

Early diagnosis and proper treatment can improve the prognosis for dogs with soft tissue sarcoma. Regular check-ups, maintaining a healthy diet, and incorporating natural supplements or TCM herbs may also contribute to overall health and cancer prevention.

While soft tissue sarcoma in dogs can be challenging, early detection and an integrated approach that includes surgery, holistic treatments, and lifestyle adjustments offer the best chances for recovery. Consult your veterinarian to explore all possible options and tailor a treatment plan that works best for your dog’s needs.
