BACKGROUND/AIM: Clinical staging has become essential in veterinary oncology. It is crucial for creating effective treatment plans and predicting outcomes. Whole-body computed tomography (WBCT) can serve as a comprehensive staging examination, offering a detailed view of a patient's internal anatomy. This retrospective study aimed to assess the diagnostic yield of WBCT in diagnosing cancer in dogs and cats.
We reviewed medical records of cats and dogs that underwent a WBCT scan between January 2016 and May 2023. Only cases with a confirmed cytological or histological diagnosis of the primary tumor and complete medical records were considered. We collected data on histological diagnoses and diagnostic methods used.
Our study included 57 animals that underwent WBCT for cancer-related reasons. Metastases were detected in 14 dogs, with four showing metastases in multiple locations, five in the lungs, three in the lymph nodes, one in the skeleton, and one in the liver, yielding a diagnostic rate of 31.8%. In cats, metastases were detected in six cases (five in the lungs and one in the lymph nodes), with a diagnostic yield of 46.2%. WBCT identified metastasis in over 35% of cases, including those outside the thoracic and abdominal cavities, indicating potentially greater accuracy than radiography and ultrasound.
WBCT is an effective and safe method for tumor staging and oncological diagnosis in dogs and cats.
背景/目的：临床分期在兽医肿瘤学中已变得至关重要。它对于制定有效的治疗方案和预测预后至关重要。全身计算机断层扫描（WBCT）可作为一种全面的分期检查，提供患者内部解剖结构的详细视图。这项回顾性研究旨在评估WBCT在诊断犬猫癌症中的诊断价值。
我们回顾了2016年1月至2023年5月间接受WBCT扫描的犬猫的病历。仅纳入原发性肿瘤经细胞学或组织学确诊且病历完整的病例。我们收集了组织学诊断和所用诊断方法的数据。
我们的研究包括57只因癌症相关原因接受WBCT检查的动物。在14只犬中检测到转移，其中4只在多个部位出现转移，5只在肺部，3只在淋巴结，1只在骨骼，1只在肝脏，诊断率为31.8%。在猫中，6例检测到转移（5例在肺部，1例在淋巴结），诊断率为46.2%。WBCT在超过35%的病例中识别出转移，包括胸腔和腹腔外的病例，表明其准确性可能高于放射学和超声检查。
WBCT是犬猫肿瘤分期和肿瘤学诊断的一种有效且安全的方法。
