What is the response rate of chemotherapy?
Response rates refer to the number of people whose tumors will respond (shrink or disappear) to the drug or drugs given. Response rates are established through research. For example, a certain type and stage of cancer might have a 70% response rate to a certain combination of drugs. This means that 70% of the people with this type and stage of tumor have a response (shrinkage or disappearance of the tumor) to this combination of drugs. It also means that 30% of the people with this type and stage of cancer will not respond to the treatment or will have only a minimal response. Responses to therapy can be either complete or partial (these are defined according to the type of cancer and the specific protocol). Another consideration in determining which drugs to give is response duration. In other words, how long do the responses last? Through research, an average response duration for any given drug protocol has been documented. Doctors choose protocols with the highest response rates and longest known durations.
