Fibrosarcoma in a young dog treated with injectable <i>Viscum album</i> therapy

Fibrosarcoma is a malignant tumor characterized by a high recurrence rate and resistance to conventional treatments in dogs. This case report presents a case of fibrosarcoma located in the esophagus, diagnosed in a young dog, potentially linked to a chronic inflammatory response triggered by a parasitic infestation. The patient was treated with injectable homeopathic Viscum album as monotherapy, given the constraints imposed by the tumor's location and the priority of preserving the dog's quality of life. After six months of treatment, the dog exhibited a clinical progression unlike the typically expected for this condition, with no evidence of tumor growth. Viscum album extracts, recognized for their immunomodulatory and cytotoxic properties, likely contributed to the observed positive clinical response by promoting cellular apoptosis and enhancing the patient's immune function. This case underscores the potential role of integrative therapies in managing sarcomas in dogs, suggesting that Viscum album may offer a promising alternative for controlling refractory tumors. Additionally, the absence of significant adverse effects highlights the safety and feasibility of this therapy, particularly in young animals. Nonetheless, further research is required to elucidate the mechanisms of action of Viscum album and its broader applications in veterinary oncology.
