The two-year prognosis for malignant mammary tumours seen in 175 bitches in the Tokyo metropolitan area was assessed based on the extent of mastectomy and on whether an ovariectomy was carried out at the time of mastectomy. The prognosis for the bitches was not influenced by the excision size of the affected mammary glands. Ovariectomy had no effect on the two-year survival rate of the dogs that underwent the tumour excision. There was no significant difference in the two-year survival rate between the dogs ovariectomised prior to mastectomy and those ovariectomised at the time of mastectomy. These results suggest that ovariectomy at the time of mastectomy has no effect on the prognosis in dogs with established neoplasms of the mammary gland.
基于乳房切除术的范围以及在乳房切除时是否进行卵巢切除术，对东京都市区175只母犬所患恶性乳腺肿瘤的两年预后情况进行了评估。母犬的预后情况不受受影响乳腺切除大小的影响。卵巢切除术对接受肿瘤切除的犬只的两年生存率没有影响。在乳房切除术前进行卵巢切除的犬只与在乳房切除时进行卵巢切除的犬只之间，两年生存率没有显著差异。这些结果表明，乳房切除时进行卵巢切除术对已确诊乳腺肿瘤的犬只的预后没有影响。
