護理師諮詢一位有大腸癌家族史的客戶，應討論哪項篩檢建議？
A nurse is counseling a client who has a family history of colon cancer. Which screening recommendation should the nurse discuss?
- ACT colonography at age 5050歲時進行電腦斷層大腸攝影
- BDigital rectal exam every year starting at age 40從40歲開始每年進行數位直腸指診
- CColonoscopy starting 10 years before the youngest relative's age of diagnosis✓ 正解在年輕患病親屬確診年齡前10年開始進行大腸鏡檢查
- DFecal immunochemical test every 5 years每5年進行一次糞便免疫化學檢測
有家族史的高風險群，篩檢策略不同於一般民眾。建議從親屬確診年齡早 10 年開始進行大腸鏡篩檢，但不得晚於 40 歲。A 糞便免疫潛血檢查（FIT）一般建議每年進行；C CT 攝影非首選；D 直腸觸診無法偵測腸道內部病變。
Screening strategies for high-risk groups with a family history of colorectal cancer differ from those for the general population. Colonoscopy is recommended starting 10 years before the youngest affected relative's age at diagnosis, but no later than age 40. Option D: a fecal immunochemical test (FIT) is generally recommended annually; option A: CT colonography is not the preferred modality; option B: digital rectal exam cannot detect intraluminal colonic lesions.
美國與台灣在大腸癌篩檢指引上趨向一致，但台灣針對家族史的預防性檢查轉介機制較依賴健檢中心推動。
