Feline Astrocytoma Overview
When it comes to brain tumors in cats, one type that veterinarians commonly encounter is feline astrocytoma. Understanding the basics of this condition, including its characteristics and the types of brain tumors seen in felines, is essential for effective diagnosis and treatment.
Understanding Brain Tumors in Cats
Brain tumors in cats can arise from various types of cells, including glial cells. Glial tumors, such as astrocytoma, oligodendroglioma, and ependymoma, are among the most common primary central nervous system neoplasms in both dogs and cats (NCBI). Astrocytoma, in particular, is frequently reported as a solid intraparenchymal mass within different areas of the brain, such as the telencephalon, brainstem, cerebellum, or spinal cord.
Types of Brain Tumors in Felines
Within the spectrum of feline brain tumors, astrocytomas are the most prevalent gliomas. They can be further classified into different subtypes, including gemistocytic astrocytoma and anaplastic astrocytoma. Gemistocytic astrocytomas are relatively rare in cats, while anaplastic astrocytomas are even rarer.
It’s worth noting that feline astrocytomas account for 3.5% of spinal neoplasias and 2.8% of intracranial neoplasias. While these tumors are uncommon, they can present significant challenges due to their location and potential for aggressive growth.

Comparing Astrocytomas in Different Animals
When it comes to astrocytomas, a type of brain tumor, there are similarities and differences between humans and cats. Understanding these comparisons can provide insights into the treatment and management of astrocytomas in feline patients.
Human vs. Feline Astrocytomas
Astrocytomas are the second most common type of spinal cord neoplasia in humans, primarily affecting children. In humans, surgical resection of astrocytomas is challenging due to their infiltrating nature, poor plane of cleavage, and blending with the spinal cord at the margins (PubMed Central). On the other hand, astrocytomas in cats primarily affect the brain. While the location and characteristics of astrocytomas may differ between humans and cats, the underlying nature of these tumors remains similar.
Surgical Approaches in Humans and Cats
In humans, surgical intervention for astrocytomas may vary depending on the tumor’s location and characteristics. An “inside-out” removal approach is recommended, where the tumor is carefully removed based on its color and consistency compared to the surrounding spinal cord. This approach aims to minimize damage to healthy tissue while achieving the best possible resection.
In cats, surgical approaches for astrocytomas in the brain would differ from those used in humans due to anatomical differences. The specific surgical technique would depend on the tumor’s location, size, and accessibility. The goal is to remove as much of the tumor as possible while preserving neurological function. However, the exact surgical approach is best determined by a veterinary neurosurgeon based on the individual cat’s condition.
Outcome Disparities
While astrocytomas in both humans and cats present challenges, there are differences in outcome disparities. In humans, the infiltrating nature of astrocytomas and their blending with the spinal cord at the margins can make surgical resection more challenging. Radical resection of these infiltrative lesions may result in higher morbidity, so a less radical intervention with minimal surgical morbidity is preferred. In cats, the outcome of astrocytoma treatment may vary depending on factors such as tumor size, location, and the overall health of the cat. The prognosis for astrocytomas in cats can be influenced by the extent of surgical resection, the use of adjunctive therapies like radiation or chemotherapy, and the individual cat’s response to treatment.
By understanding the similarities and differences between astrocytomas in humans and cats, veterinary professionals can tailor treatment approaches to feline patients. While surgical techniques and treatment outcomes may not directly translate from humans to cats, the knowledge gained from human medicine can contribute to advancements in feline astrocytoma therapy. Ongoing research and clinical trials continue to explore new treatment options and address the specific needs of cats with astrocytomas.
