Plain-English summary

A cat with a lump at the site of a recent vaccination may be dealing with a vaccine-associated sarcoma, a type of cancer that can develop in response to vaccines. It's crucial for pet owners to notice these masses early, as prompt treatment can help prevent the cancer from spreading. The best approach for managing this condition often involves a combination of surgery to remove the tumor, along with radiation and chemotherapy to target any remaining cancer cells. With timely intervention, many cats can have a better outcome and improved quality of life.

Abstract

In the last decade, there has been a great deal of information surrounding the etiology, diagnosis, and treatment of feline vaccine-associated sarcomas. The presence of a mass in areas used for subcutaneous or intramuscular injections should alert the clinician to the possibility of a vaccine-associated sarcoma. Early detection and subsequent treatment is paramount to limit local invasion and distant metastasis. The current data are suggesting that a team approach with multi-modality therapy is the appropriate way to address this disease. In the following article, we will discuss the history/incidence, pathology, diagnosis, and current treatment options, which include a combination of surgery, radiation, and chemotherapy for vaccine-associated sarcomas.
