HI everyone, i know this sounds like a really obscure question but does anyone know the expected trend in the decline of ca125 levels during treatment? i know they aren't a reliable marker but i'm just curious. my mum has OV/C stage 3c she had ca levels around 400 when she was diagnosed, she saw a gradual decline in the numbers since. she's on her 5th chemo session so she's now nearing the end of treatment thank god, last chemo she was 29 and this chemo that she had a few days ago she was only 27. it hasn't dropped much. the doctor just said its under 35 so it's a normal healthy level and it's likely to just stay stable at that level now. but i'm just wondering what it means. i've head of people having markers in the1000's and then after surgery it rapidly drops to as low as 6/5. is there a difference between patients who drop to lower numbers rapidly?
sorry again for how pedantic this question sounds haha!
