乳がんの腫瘍マーカー（CA15-3）の使い方 【補足】人間ドックのCA19-9について

This time, we'll be talking about tumor markers. (If you're interested, please also watch the previous video on CEA.) CEA increases with smoking. ~A prelude to tumor markers~    • CEAは喫煙で上がる。～腫瘍マーカーへの前奏曲～   How reliable are tumor markers? How should they be used? Basically, they're best used to monitor recurrence and treatment response. Also, interpretation is difficult with only one or two points. It's important to look at a trend (line) of at least three or more points. Of all tumor markers, PSA (prostate cancer) is by far the most reliable. CA15-3 for breast cancer and CA125 for ovarian cancer are also fairly reliable. However, for some patients, their levels never rise even after recurrence, and they are useless for them. Also, CA19-9 may be slightly elevated during a health checkup. It's not uncommon for various tests, including CT, MRI, GI camera, and PET, to reveal nothing. CA19-9 is a marker with a very high false-positive rate. In such cases, it is important to combine it with other adenocarcinoma markers and monitor the progression (as a line, not a dot). #tumormarker #CA15-3 #CA19-9 #breastcancer #healthcheckup [Recommended] ★The online version was released on November 15, 2022!
