Abstract

ObjectivesTo describe the clinical features and oncologic outcome for cats with primary rib tumours.Materials and MethodsMedical records for cats with surgically treated primary rib tumours from six veterinary referral centres were reviewed. Signalment, preoperative clinical signs, reconstruction technique, and surgical and oncologic outcome were retrieved from medical records or by telephone interview with owners and/or referring veterinarians.ResultsOf the eight cats with primary rib tumours, three had hemangiosarcoma, two had osteosarcoma and one cat each had chondrosarcoma, osteochondroma and osteoma. The size of the primary rib mass ranged from 2 x 2 x 1.6 cm to 9 x 7 x 7.5 cm. Three minor and one major complication developed during the immediate post-operative period. Surgery consisted of thoracic wall resection in all cats. All animals survived the procedure and the median time to discharge was 3 days. The survival time for benign tumours was 150 (case 5) and 466 (case 4) days, while for malignant tumours ranged from 105 to 550 days (cases 1 to 3, cases 6 to 8).Clinical SignificanceHemangiosarcoma and osteosarcoma were the most represented primary rib tumours in this cohort of cats. Wide surgical excision and adjuvant chemotherapy is recommended for cats with hemangiosarcoma and osteosarcoma, but the prognosis remains guarded. Prognosis appears to be fair for the other tumour types.
