I asked the question before if rytuxin was a chemotherapy drug. 50% of the doctors said no and the other 50% said yes. So what is the true answer?

In brief: Chemo
Chemotherapy can have 2 meanings- 1st- is treatment given to kill cancer.
2nd. Many of us use chemotherapy as a term for cytotoxic chemotherapy/regular chemo. Nowadays, in addition to regular cytotoxic chemo, we also have many biological tx/antibody/targeted tx/smart pill etc. Those new therapy are not cytotoxic chemo. Rituxan (rituximab) is an atibody against cd 20-is a targeted tx-not cytotoxic chemotherapy.

In brief: The answer is
That it is not chemotherapy.
It is anti-cancer therapy. Chemo kills indiscriminately, causing toxicity to a variety of organs, this agent is directed to a specific target, the cd-20 receptor. To quote/parapharase a the famous "few good men" line, you have been given the truth, but you can't handle (understand) it. Why do you need the distinction?

One could argue that Rituxan also "kills indiscriminately" since all normal B-cells are CD20 positive and Rituxan kills off your B-cells for quite a number of months, depending on the regimen. It all depends on how you define chemotherapy. Also, just to play Devil's advocate, Rituxan has many non-oncologic uses....
