The lack of a reaction to chemotherapy should be a good thing, but you can’t judge whether it’s working well or poorly based on whether or not there’s a reaction to chemotherapy alone. Patients are advised to determine how effective the chemotherapy is by checking imaging and tests like gastroscopy and colonoscopy. Because there is no response to chemotherapy does not mean that chemotherapy is not effective. The continuous research and development of new drugs, the increase of drug purity and the use of auxiliary drugs in the process of chemotherapy can reduce the reaction of chemotherapy to a certain extent. It is recommended that patients pay attention to the daily intake of nutritious food, because the nutritional status is better, to avoid the occurrence of anemia, lowering of white blood cells, etc., to improve the patient’s resistance and return to normal as soon as possible, and if there are any abnormalities, it is recommended to go to the hospital in a timely manner.
