Overall median time to progression (TTP) with first line medical treatment was 99 days (range 32-317 days). Four cats had evidence of disease progression while on chemotherapy and received rescue treatment, with a TTP ranging from 8 to 85 days. In 2 cases, only a clinical response could be assessed; of these, one had renal metastases at diagnosis and the other developed renal metastases while receiving treatment. These two patients initially demonstrated stable disease but later developed intraocular and retrobulbar metastases, respectively. Of patients with repeat imaging, 1 cat had a partial response, 6 had stable disease and 4 progressive disease. The overall median survival time was 139 days (range 50-497 days). Four cats were still alive at the time of data analysis with a median follow-up of 428 days (range 81-625 days).
