Plain-English summary
A group of 57 cats with injection-site sarcomas (tumors that can develop at vaccination sites) were treated in Italy and Switzerland. These cats underwent various tests, including advanced imaging, to assess the tumors. Treatment options included surgery to remove the tumors, and in some cases, radiation or chemotherapy was also used. The study found that cats with more aggressive tumors (grade 3) had a higher chance of the cancer spreading to the lungs and shorter survival times. Overall, cats that survived the treatment lived for about 600 days, while those that didn't survive lived around 272 days.

Abstract
In this retrospective study of cases from Italy and Switzerland, the clinical features of injection-site sarcomas in 57 cats were reviewed. In addition to routine physical, laboratory, and radiographic examinations, advanced imaging (computed tomographic scans) was conducted to delineate tumor extent. Treatment was by wide surgical excision including partial scapulectomy, spinous process removal, and amputation (appendicular lesions). Radiotherapy and chemotherapy were also used. The results revealed that cats with grade 3 tumors were most likely to develop distant pulmonary metastases (and to have shorter survival rates); this occurred in 21% of the cases.Median follow-up for cats that survived (51%) was 600 days; for those that died (49%), it was 272 days. In this study, tumor size, as measured manually by calipers, was not a prognostic factor. Furthermore, factors associated with local recurrence were not identified. The authors recognized the limitations of a retrospective study, especially with regard to treatments before referral.
