Epidemiological, clinical and pathological evaluation of overall survival in canines with mammary neoplasms

ABSTRACT Canine mammary neoplasms (CMNs) are the most frequent lesions and in female dogs. However, studies correlating pathological criteria with clinical evolution in female dogs with mammary neoplasms are scarce. The present study aims to present epidemiological, clinical-pathological and overall survival data to help establish the prognosis and understand the biological behavior of CMNs. A total of 1539 cases were included (85% malignant and 13% benign). Tumor size was an important prognostic factor and was associated with overall patient survival (P摘要：犬乳腺肿瘤（Canine Mammary Neoplasms, CMNs）是雌性犬最常见的肿瘤性病变。然而，目前针对乳腺肿瘤雌性犬的病理学特征与临床转归相关性的研究仍较为匮乏。本研究旨在公布流行病学、临床病理学及总生存期相关数据，以期为犬乳腺肿瘤的预后判定提供参考，并阐明其生物学行为。本研究共纳入1539例病例，其中85%为恶性肿瘤，13%为良性肿瘤。肿瘤大小是重要的预后影响因素，与患犬的总生存期密切相关（P
