安坐家中 完成大腸癌篩檢 | 何鴻光醫生 腸胃肝臟科

何鴻光醫生

The early symptoms of colorectal cancer include tumours or polyps in the colon and usually associates with blood in the stool. Therefore, a Faecal Occult Blood Test (FOBT) can be conducted to see if there is any blood in the stool by collecting stool specimens in tubes and sending them to the laboratory. The test is a preliminary method to screen for colorectal cancer and it is a non-invasive test that is safer and more convenient. Colorectal Cancer Screening Programme launched by the Department of Health utilises the FOBT to find people who are at risk of having colorectal cancer and provide a colonoscopy for those who have blood in the stool. Contact us for more information about the Colorectal Cancer Screening Programme and the Faecal Occult Blood Test.

加入基因檢測技術

現時常用的大腸癌篩查方法包括大便隱血測試和大腸鏡。前者雖然方便,但對於小型腺瘤和癌前病變的靈敏度較低;大腸鏡則為診斷的黃金標準,而且過程中可同時切除息肉,不過就要事先作低渣飲食,並服用瀉藥清理腸道。最新引入香港的多靶點糞便基因測試,則於大便隱血之外加入基因檢測。Prenetics研究及發展部主管馬湖波博士指出,「大腸癌在病變過程中,細胞內突變的DNA會不斷脫落到糞便中。通過檢測糞便中血液和突變DNA,就可作為非侵入性大腸癌篩查的有效工具。」

靈敏度達九成半

一項有4,758位參與者的臨床研究發現,多靶點糞便基因測試對於大腸癌及進展期腺瘤(癌前病變)的靈敏度分別達到95.5%及63.5%,於非侵入篩查中最為準確;而且對大腸癌的陰性預測值為99.6%,即甚少出現假陰性,有效避免漏診。

家庭醫生關博文補充,「疫情下遙距醫療需求上升,大腸鏡等非緊急程序亦可能延遲,多靶點糞便基因測試適合在這時候為市民作大腸癌篩查。有需要的市民可諮詢醫生,是否適合這種篩查方式。」之後使用者可從診所或郵遞取得測試套裝,在家完成糞便樣本採集後,將樣本寄回實驗室,5個工作天後便有結果。陰性結果的話可每2至3年檢測一次,陽性結果代表可能患有大腸癌、晚期腺瘤或良性腫瘤,應盡快求醫跟進。

藝人方力申在過去3年做了兩次大腸鏡檢查,原因是藝人工作飲食不定時,比較擔心腸道健康,幸而結果一切正常,也沒有息肉。最近他亦試用多靶點糞便基因測試,認為檢測過程方便得多,只有檢測結果呈陽性並諮詢醫生後,才需進一步做Colonoscopy.
