Medical records of fifty-three cats diagnosed as malignant mammary tumor from 1982 to 1993 were reviewed. The mean age of the cats at diagnosis was 11.1 years, and Japanese domestic and Siamese breeds were predominant. Survival rates after 1 and 2 years of diagnosis were 31.8% and 17.7%, respectively, suggesting poor prognosis of this malignancy. The survival time was significantly associated with tumor size or WHO clinical stage, but not with breed, age, or gender. Twenty-nine cats with pulmonary metastasis died within 5 months following metastatic detection. Postoperative prognosis was significantly related to the tumor size at surgery, but not with type of surgery and adjuvant chemotherapy using cyclophosphamide and/or vincristine.
回顾了1982年至1993年期间53只被诊断为恶性乳腺肿瘤的猫的病历。诊断时猫的平均年龄为11.1岁，日本本土品种和暹罗品种占主导。诊断后1年和2年的生存率分别为31.8%和17.7%，提示该恶性肿瘤预后不良。生存时间与肿瘤大小或世界卫生组织临床分期显著相关，但与品种、年龄或性别无关。29只发生肺转移的猫在检测到转移后5个月内死亡。术后预后与手术时的肿瘤大小显著相关，但与手术类型以及使用环磷酰胺和/或长春新碱的辅助化疗无关。
