- Abstract: The purpose of this retrospective study was to describe cases of feline intermediate- to high-grade alimentary lymphoma regarding signalment, clinical presentation, laboratory findings, response to therapy (modified 25-week University of Wisconsin–Madison [UW-25] vs. COP [cyclophosphamide, vincristine, prednisone]), toxicosis, and outcomes and to identify prognostic factors. Sixteen cats were treated with chemotherapy protocols. Response rates and survival did not differ statistically between the two protocols. The progression-free interval (PFI) and median survival time (MST) in cats achieving a response to therapy were longer than in those with no response [NR] (complete remission [CR] vs. partial remission [PR] vs. NR; PFI, 124 vs. 49 vs. 12 days, p < 0.001; MST, 361 vs. 118 vs. 16 days, p < 0.001). Clinical stage was another prognostic factor for PFI and MST. The PFI and MST in cats in stage I were longer than in those in other stages (PFI, 107 days vs. 30 days; MST, 193 days vs. 54 days). Hematologic and gastrointestinal toxicosis was mostly low grade. In comparing the modified UW-25 protocol with the COP protocol, there was not much difference in the number of neutropenic episodes and grade levels.
