大腸疾患におけるAI診断

Endoscopic Diagnosis of Colorectal Tumors Using Artificial Intelligence

要旨●大腸癌は，前癌病変である腺腫や早期癌を内視鏡的に早期発見し，切除・治療することで，大腸癌罹患率のみならず，死亡率まで減少することが証明されている．ADRがPCCRCの発生頻度と逆相関するため，AIによる見逃しのない内視鏡検査と質的診断の補助が望まれる．現在国内においてEndoBRAIN®シリーズ，CAD EYE^TM，WISE VISIONと3種類のAIが薬事承認され，AIによる大腸腫瘍性病変のdetection（病変発見）からcharacterization（質的診断）まで可能な時代となっている．

　Early detection, resection, and treatment of precancerous adenomas and early-stage cancers have been proven to reduce not only the morbidity but also the mortality associated with CRC（colorectal cancer）. Because of the inverse correlation with the incidence of post-colonoscopy CRC, it is desirable to use AI（artificial intelligence）to aid in endoscopy without missing anything. At present, three types of AI, i.e., ENDOBRAIN, CAD-EYE, and WISE-VISION, have been approved by pharmaceutical authorities in Japan and are capable of detecting colorectal tumors and assisting in their characterization.
