All medicines must be rigorously tested and proven in double-blind clinical trials before they can be licensed and used.
There are many different chemotherapy drugs and all have been subject to double-blind clinical trials.

Well, in my case of leukemia, after each round of chemo I had a bone marrow biopsy to dertimine the number of cancerous cells. My uncle had throat cancer, and they did scans I believe. My aunt had hormonal colon cancer. Her treatment was only to lengthen her time by a few months, but they did scans and when the cancer quit responding, they quit the chemo.

Ask anyone who had cancer that was treated with chemo & is still alive how "effective" it is! What a silly question!
When chemotherapy is appropriate, it works, & it is most often completely effective!
Now what is your REAL question?

Well, if you have a cancerous tumor and have chemotherapy to try and shrink it and/or get rid of it, a scan is performed to see if the tumor did indeed shrink.

They can do blood work to check the tumor markers. There are CT scans and PET scans which also can tell what is going on.
