AI-powered tool helps doctors boost detection of colorectal polyps

AI-powered tool helps doctors boost detection of colorectal polyps

2022-09-27

National Taiwan University Hospital and Cathay General Hospital are taking advantage of a new AI-powered tool that can boost detection of polyps in the large intestine. The tool can help doctors detect problems early, allowing patients to undergo treatment to prevent colorectal cancer. For 14 years now, colorectal cancer has been the most common cancer in Taiwan, killing 6,600 people in 2021.

Thanks to regular checkups and early intervention, stage 1 colorectal cancer can be cured in more than 90% of patients. In Taiwan, about 400,000 people go through checkups for the disease every year. But doctors say that maintaining good quality checkups and high detection rates is no easy task.

Not all doctors have experience in diagnosing flat or sunken polyps. Doctors most frequently miss these types of polyps.

According to studies from abroad, experts conducting colonoscopies fail to detect 23% of polyps smaller than 5 millimeters.

Doctors say the accuracy of colonoscopies varies depending on the doctor’s clinical experience and their ability to notice abnormalities. Polyps that are very small or located on bends in the large intestine can be easy to miss. To improve detection, National Taiwan University Hospital and Cathay General Hospital collected and contributed more than 3,000 medical records of patients to create an AI polyp-detection tool with a developer. The tool can detect growths at a speed of 30 images per second with an accuracy of 95%. It can help doctors detect adenoma with between 14% and 30% more accuracy.

Overall, for every 1% increase in the detection of adenoma, we can reduce the likelihood of colorectal cancer development by 3% after an endoscopy.

When it’s a small polyp, the AI detection system can circle it and bring it to the doctor’s attention, highlighting it as a potential polyp.

The AI system can help doctors detect polyps and has already been certified as medical equipment by the FDA. Hospitals say they will test the tool to see whether it does indeed improve the quality of analyses. To prevent severe disease, doctors advise people aged 50 and up to go for regular fecal occult blood tests. If the tests come back positive, seek medical help as soon as possible and get a colonoscopy. Waiting for a long time can allow polyps to grow and become cancers, making treatment more complicated.


全新"AI 瘜肉偵測系統" 早期發現治療大腸癌

2022-09-27

大腸癌連續14年蟬聯"癌王",光是去年就奪走6600多條人性命。台大和國泰醫院合作,蒐集超過3000名患者紀錄,與業者開發AI瘜肉偵測系統,其中腺瘤偵測率,平均提升14到30%,期盼能揪出不容易發現的病灶。

透過定期篩檢、早期發現,大腸癌初期治癒率超過九成。全台每年約40萬人做大腸鏡檢查,但想維持一定品質和偵測率,並不容易。

“並不是所有的醫師,對於那種扁平型或是凹陷型的瘜肉都有診斷的經驗,這個也是最常被疏漏的。”

[[台大醫院健康管理中心主任 邱瀚模]]
“小於5mm的小瘜肉遺漏率,根據國外的研究,而且是專家做的大腸鏡,遺漏率是23%。”

醫師指出,現行大腸鏡檢查,大多靠醫師的臨床經驗與肉眼判斷,有些瘜肉如果範圍太小,或受到腸道轉彎和角度影響,很有可能被忽略。為了提升判讀能力,台大和國泰醫院合作,蒐集超過3000名患者紀錄,與業者共同開發,AI瘜肉偵測系統,學習找出病灶,目前每秒可辨識30張影像,精準度約95%,其中腺瘤偵測率,平均提升14到30%。

[[台大醫院健康管理中心主任 邱瀚模]]
“整體來講,我們的腺瘤偵測率每增加1%,我們後面發生間隔癌,也就是說,做完大腸鏡之後還發生大腸癌的機會,可以降低3%。”

[[國泰醫院消化內科主任 洪志聖]]
“這麼小的一個瘜肉,這個AI偵測系統可以把它認為,可能是瘜肉的地方先框住,提示醫師是說,這個地方可能有瘜肉存在。”

自動鎖定揪出瘜肉,系統取得食藥署智慧醫材許可,院方也進一步規劃試驗,確定是否真能改進檢驗品質。醫師提醒,50歲以上民眾,務必定期做糞便潛血檢查,一旦發現陽性,就要盡早就醫、進一步做大腸鏡篩檢,否則萬一等到瘜肉惡化、變成癌症,恐怕失去黃金治療時機。
