This is one of the most common questions in my oncology practice. Firstly, there are 2 types of chemo. The type most people are familiar with is given in hospital every 1-4 weeks. The doses used in veterinary oncology produce mild side effects in 10% and serious side effects in 5%, meaning 5 out of 6 dogs have no problems. Just as importantly, if a dog does have problems, it is simply a matter of reducing the dose the next time. The second type of chemotherapy is called metronomic, and is given by mouth at home every day or 2. Side effect rates are similar overall but less likely to be serious. Importantly you should be aware that the use of chemo is based on research showing a particular drug(s) at a certain dose and frequency is effective against a particular cancer. This means that in some cases both types of chemo are appropriate and in others neither are. There are many types of sarcoma. For the less aggressive ones, metronomic therapy is often used. For the very aggressive ones, both might be recommended. Your oncologist will discuss this with you.
