If the response is large, such as nausea, loss of appetite, weakness, decreased white blood cell and platelet counts, can reduce the amount of time, or increase the interval. Significant bone marrow suppression can be promptly discontinued. Gastrointestinal side effects by oral administration than intravenous great, but bone marrow suppression response to light.
Must pay attention to supportive care during treatment and for the reduction of side effects. Failure patients undergoing resection of cancer chemotherapy, alleviate symptoms of a certain role in controlling tumor growth, but less effective, maintain a short time, if the patient generally bad, significant side effects, but aggravate the disease, should not be applied.
