Abstract | BACKGROUND: HYPOTHESIS: GEM and CARBO are safe for the treatment of dogs with carcinomas. ANIMALS: Thirty-seven dogs with histologically or cytologically confirmed carcinomas. METHODS: Prospective clinical trial. Dogs were treated with GEM (2 mg/kg, 20-30-minute infusion IV) on Days 1 and 8 and 4 hours later, CARBO (10 mg/kg IV) on Day 1. The cycle was repeated on Day 22. RESULTS: Thirty-seven dogs (29 with measurable tumor) received a median of 2 cycles (range 0.5-6) for a total of 101 cycles administered. Twelve dogs (32%) developed neutropenia (3 Grade 3, and 5 Grade 4) and 9 (24%) thrombocytopenia (2 Grade 3, and 1 Grade 4). Dogs >20 kg were twice as likely to develop thrombocytopenia (P= .023). Twenty-seven dogs (73%) had evidence of gastrointestinal (GI) toxicosis, but most signs were of mild to moderate severity and self-limiting. One dog died of treatment-related complications. Overall tumor response rate was 13%. One dog with metastatic prostatic carcinoma achieved a complete remission and 1 dog with intestinal adenocarcinoma and 1 with tonsillar squamous cell carcinoma achieved partial remission. Twelve dogs achieved stable disease for a median of 72 days. CONCLUSION AND CLINICAL IMPORTANCE: GEM and CARBO combination causes mild to moderate hematologic and GI toxicosis in dogs with carcinoma. Response rate in this study was modest, and optimization of dosing of this combination is required.
