犬乳腺腫瘤預後與荷爾蒙受體及HER-2/neu表現之關係

Relationships between Prognosis, Hormone Receptors and HER-2/neu in Canine Mammary Gland Tumors

摘要


本實驗收集自1995年至2003年台灣地區公立動物教學醫院、私人動物醫院及診所,經外科手術取得之犬乳腺腫瘤病材,進行組織病理學、ER及PR免疫組織化學染色及腫瘤惡性指標HER-2/neu免疫組織化學染色之分析,並配合臨床基本資料,以分析存活時間及存活率與荷爾蒙受體及HER-2/neu之相關性,期藉此分析犬乳腺腫瘤預後相關因子。在ER與PR相關表現,由目前所分析35個病例中,ER的陽性率為25.7 %(9/35)其中良性佔33.3 %(5/15),惡性佔20.0 %(4/20),PR的陽性率為85.7 %(30/35)其中良性佔93.3%(14/15),惡性佔80.0 %(16/20);就兩者於腫瘤中共同表現的情形,ER+PR+為22.9 %(8/35),ER+PR-為2.9 %(1/35),ER-PR+為62.9 % (22/35),ER-PR-為11.4 %(4/35)。HER-2/neu 於79例犬乳臉腫瘤中之表現,具過度表現有42例,佔53.2 %,其中惡性病例為24例,佔51.1 %(24/47),良性病例有18例,佔56.3 % (18/32),在18例良性病例中,Benign mixed tumor 佔12例(12/79),佔所有病例15.2 %。本研究共進行39例犬乳房腫瘤病例術後追蹤, 22例惡性病例存活時間問期為1個月至3年, 平均12.7個月,63.6%(14/22)病例存活時間少於一年,因腫瘤死亡者死亡率為59.1%(13/22),17例良性病例為1年至3.5,平均為22 .7個月,100%(17/17)存活時間一年以上【一年者11.8%(2/17)、一年以上未滿兩年佔41.2%(7/17)、兩年以上未滿三年佔29.4 %(5/17)及三年以上佔17.7%(3/17)】。免疫組織化學染色結果顯示惡性犬乳腺腫瘤較良性腫瘤ER與PR表現較差,HER-2/neu 過度表現比例高,相似於人類乳癌,術後存活時間則較良性平均約短10個月。

Mammary gland tumor is a spontaneous and common disease in aged dogs. In the past decades, canine mammary gland tumors have been chosen as a potential etiological, pathogenetic, and therapeutic model for human breast tumor, but very little or limited studies are known about the mammary gland tumor in Taiwan. In 139 dogs with mammary gland tumor of our study, the ER positive rate was 25.7% (9/35) including 33.3% (5/15) of benign cases and 20.0% (4/20) of malignant cases. PR positive rate was 85.7% (30/35) including 93.3% (14/15) of benign cases and 80.0% (16/20) of malignant cases. The ratios that both ER and PR positive (ER + PR +) was 22.9% (8/35), ER + PR - was 2.9% (1/35), ER–PR + was 62.9% (22/35), and ER - PR was 11.4% (4/35). The HER-2/neu overexpression rates were 53.2% (42/79) which consisted of 51.1% (24/47) of malignant cases and 56.3% (18/32) of benign cases. Among the benign tumors, benign mixed tumor was diagnosed in 12 cases and HER-2/neu overexpression rate was 15.2%. Retrospective study of the survival time was evaluated in 39 cases. The malignant and benign survival intervals were 1 to 36 month (12.7 months in average) and 12 to 42 months (22.7 months in average). In malignant cases, 63.6% (14/22) of survival time was less 1 year, and mortality caused by tumor recurrence was 59.1% (13/22). In 17 dogs with benign tumors, survival time was all over 1 year. On conclusion, the malignant tumors had less expression of ER and PR and shortening survival time than benign cases, but HER-2/neu overexpression was inconclusive.
