〔記者侯家瑜/台北報導〕大腿痛竟是骨肉瘤!當年22歲的王小姐大腿痛2個多月,確診惡性骨肉瘤,接受化療及台北榮總「免截骨原位冷凍」技術保肢。如今術後已5年多,曾發生肺轉移但已接受手術切除,目前持續追蹤、生活健康。

北榮骨科部關節重建科主任吳博貴表示,骨肉瘤治療不能只靠手術,通常需先接受2個多月術前化療,再進行腫瘤廣泛性切除及骨骼重建,術後還要持續約6至8個月化療。手術除了要把惡性腫瘤連同周邊一定範圍的正常組織完整切除,避免腫瘤細胞殘留,也要立即處理切除後留下的大範圍骨缺損,盡可能保留患者站立、行走及活動能力。

目前大型骨骼缺損重建主要有腫瘤型人工關節及生物性重建2大方向。人工關節是利用金屬人工關節及植入物取代被切除的骨骼,但長期仍可能面臨人工關節鬆脫等問題;生物性重建則是將腫瘤骨經特殊處理殺死癌細胞後,再將原本的骨頭放回患者體內。

其中,液態氮冷凍就是生物性重建方式之一。傳統作法需先把含腫瘤的骨頭完整截斷、取出體外,再放入攝氏零下196度液態氮中冷凍約20分鐘,經回溫後重新放回原處並以鋼板固定。吳博貴指出,傳統截骨重建後,骨頭平均約需10個月癒合,期間患者可能需要長時間使用拐杖,也可能發生骨頭不癒合等問題,影響肌力及功能恢復。

為減少截骨造成的負擔,北榮發展「免截骨原位冷凍」生物性重建技術,最大特色就是不必把整段骨頭完全截斷,而是在骨頭仍與身體相連的狀態下,直接於體內完成液態氮冷凍處理,再保留原有骨骼結構。吳博貴表示,若病患條件適合,術後最快隔天就能下床活動,部分患者甚至僅需使用拐杖1、2天,相較傳統方式平均約需10個月,功能恢復可望更快;此外,手術也可省下取出骨頭、重新復位及鋼板固定等時間,平均可縮短近2小時。

不過,這項技術並非人人適用。吳博貴指出,關鍵在於腫瘤切除後的骨頭結構仍要完整,如果腫瘤已將骨頭破壞、掏空,結構不足以支撐,就較不適合直接使用原位冷凍,醫療團隊可能改採人工關節或利用骨庫捐贈骨骼進行重建。

這項手術最大的挑戰之一,是如何避免液態氮低溫傷害周邊正常軟組織。吳博貴說,液態氮溫度達攝氏零下196度,冷凍過程中必須將骨頭與周邊軟組織仔細分離,並利用手術技巧、手套及紗布等作為隔絕,避免造成凍傷。

回想當年治療,王小姐表示,最初只是右大腿疼痛,沒想到檢查竟發現腫瘤,確診後還得面對化療及手術,一度因害怕掉髮、體力下降及治療副作用而感到無助。化療期間多次住院,甚至痛到正常走路都很困難,但在家人、朋友及醫療團隊支持下,她仍一步步撐過療程。

吳博貴提醒,原發性惡性骨腫瘤在台灣每年約120例,骨肉瘤多好發於國中、高中階段,20、30歲族群也可能發生,通常沒有明確的抽菸、喝酒等生活風險因子,後續仍須長期追蹤,才能及早發現局部復發或遠端轉移。

王小姐原本熱愛跳舞及運動,醫療團隊治療時也盡可能保留她的肢體與關節功能。(記者侯家瑜攝)
