| Abstract: | Fourteen dogs and 11 cats with various malignant tumors were treated daily with benzaldehyde at a dosage rate of 10 mg/kg of body weight, orally, divided into 4 doses. Clinical signs of toxicosis were not observed. A partial response (greater than 50% regression) was observed in animals with an oral squamous cell carcinoma and an oral melanoma. A minimal response (less than 50% regression) was observed in animals with a sweat gland adenocarcinoma and a mast cell sarcoma. One dog with an oral melanoma had stabilization of tumor growth for 8 weeks. Seemingly, benzaldehyde has only minimal anti-tumor activity at the dose studied. |
