Abstract

Mammary adenocarcinomas with metastases are more common in dogs than in cats. Their incidence is 1 in every 4,000 cats. In routine veterinary practice, laboratory exams for diagnosis of these neoplasms are nonspecific and scarcely used. Even though invasive procedure, biopsy, and histopathological findings are the gold standards that define the clinical approach, the clinical evaluation, and image assessment lead the way to the proper treatment, especially when surgical intervention is a possibility. This study describes the clinical signs, histopathological aspects, radiological and scintigraphic findings of a cat with mammary adenocarcinoma and metastases evaluated one hour after intravenous administration of 99mTc-thymine. Our focus was not to discuss the pathological aspects of the disease but the Nuclear Medicine role in metastases detection. Metastases, when lesser than 4mm, could go unnoticed by radiological exams, whereas scintigraphy may detect them. Using 99mTc-thymine scintigraphy, we successfully detected unsuspected metastases in the lungs, liver, and right kidney. Early diagnosis is the key to a better rate of survival due to the given treatment and prognostic. Hence, we strongly recommend the use of 99mTc-thymine scintigraphy as a complementary tool for breast cancer diagnosis in veterinary care.
用99mtc胸腺嘧啶显像检测猫乳腺腺癌转移
转移的乳腺腺癌在狗身上比在猫身上更常见。它们的发病率为每4000只猫中就有1只。在常规兽医实践中,诊断这些肿瘤的实验室检查是非特异性的,很少使用。尽管侵入性手术、活检和组织病理学检查结果是定义临床方法的金标准,但临床评估和图像评估为正确治疗指明了道路,尤其是在可能进行手术干预的情况下。本研究描述了一只猫在静脉注射99mTc-胸腺嘧啶一小时后评估的乳腺腺癌和转移的临床症状、组织病理学方面、放射学和闪烁扫描结果。我们的重点不是讨论该疾病的病理方面,而是讨论核医学在转移瘤检测中的作用。当转移瘤小于4毫米时,放射学检查可能不会注意到,而闪烁扫描可能会检测到。使用99mTc-胸腺嘧啶闪烁显像,我们成功地检测到肺、肝和右肾中未被怀疑的转移。由于给定的治疗和预后,早期诊断是提高生存率的关键。因此,我们强烈建议在兽医护理中使用99mTc-胸腺嘧啶闪烁显像作为乳腺癌症诊断的补充工具。
