1臨床資料
患者,男,53歲,因\"左陰囊腫物3個月\"于2009年3月就診我院。查體:左側附睪捫及2 cm×2 cm×1.5 cm腫物,表面欠光滑,質地較硬,輕度壓痛。輔助檢查:彩超:左附睪體部可探及大小約1.3 cm×1.1 cm低回聲結節,內回聲不均勻。胸部CT:雙肺多發結節灶,考慮肺轉移可能性大。于2009年3月19日在硬膜外麻醉下行\"左側睪丸、附睪及腫瘤切除術\",術中見:腫瘤大小約1.5 cm×1.5 cm,質地硬,位于精索上,與睪丸有粘連。術后病理:左精索粘液腺癌(考慮轉移)。術后為尋原發灶,行電子結腸鏡、電子胃鏡、腹部及盆腔增強CT均未見異常。血腫瘤標志物:CEA 11.86 ng/ml CA199 84.64 U/ml FREEPS/PSA-HYB 0.28 PSA-Hyb 0.68 ng/ml freePSA 0.19 ng/ml,高度懷疑消化系統來源的轉移性腫瘤。術后4個月再次復查腹部增強CT提示胰尾部占位。行彩超引導下穿刺活檢術,病理:粘液腺癌。最終證實原發灶為胰腺來源。后給予積極全身化療,生存15個月,最后死于多臟器功能衰竭。
2討論
精索的轉移性腫瘤極為少見,胰腺癌精索轉移的病例更為罕見,至2005年日本全國共報道胰腺癌精索轉移14例[1],截止2012年我國共報道5例[2-5]。附睪轉移性腺癌的轉移途徑有血管、淋巴管、直接浸潤、腹膜種植、逆行擴展等[6],本例患者轉移途徑尚不能明確。以胰腺為原發灶的附睪轉移性腫瘤預后極差,目前尚未有生存期的報道。本例患者在胰腺原發灶癥狀未出現前就發生了遠處轉移,但在積極給予以\"吉西他濱、奧沙利鉑\"等藥物為主的全身化療后獲得了15個月的生存期,大大超過了預期。因此,在臨床中發現精索轉移性腫瘤,應高度懷疑胰腺來源,早期行根治性附睪腫物切除術,如果患者身體條件許可,根據病情盡早行化療或放療。
