The number of days of hospitalization for targeted therapy needs to be decided according to the chemotherapy protocol. Usually, it takes 3 to 5 days of hospitalization to do an intravenous targeted therapy, while some malignant tumors are treated orally for targeted therapy, which can be done without hospitalization. Targeted therapy is mainly aimed at the protein molecules in the patient’s tumor cells to carry out specific treatment for them, because some targeted drugs, which are more potent, are prone to adverse reactions and need to be admitted to the hospital for observation, the use of this part of the drug requires hospitalization. Typically, a targeted therapy with intravenous medication requires about 3-5 days of hospitalization. Some drugs can be taken orally and have fewer side effects, and can even be used in outpatient clinics without hospitalization. It is recommended that patients under the guidance of local doctors in regular hospitals to carry out standardized treatment, and patients need to go to the hospital regularly for review after targeted therapy, and if the patient is not feeling well, he or she needs to go to the hospital in a timely manner, and do not take medication on his or her own.
