Which of the following statements is true regarding the survival time for cats with osteosarcoma?

The assertion that cats with osteosarcoma have a longer survival time compared to dogs is supported by several factors related to the biological behavior of osteosarcoma in these two species. Osteosarcoma is a highly aggressive bone tumor that is more common in dogs than in cats. In dogs, it often presents with a poor prognosis and has a tendency for early metastatic spread, leading to a generally shorter survival time. In contrast, while cats can also develop osteosarcoma, the incidence is significantly lower, and their tumors often display a different behavior.

Research shows that cats with osteosarcoma tend to have a more favorable response to treatment and can achieve longer survival times following amputation and adjunctive therapies, such as chemotherapy. This improved outcome may be attributed to differences in tumor biology and the overall health status of cats, which often contributes to a better prognosis when they develop osteosarcoma.

Consequently, the survival time for cats with this condition is often longer when compared to that of dogs, making the statement regarding the survival advantage in cats the correct one.
