Does Ziv-aflibercept need to be taken for life?

Ziv-aflibercept (Ziv-aflibercept), a drug that targets vascular endothelial growth factor (VEGF), is an option for people whose cancer has progressed or has become resistant to initial therapies used to treat metastatic colorectal cancer (mCRC). In the treatment of colorectal cancer, aflibercept usually needs to be injected every two weeks (14 days) and needs to be injected continuously for several months or even longer until the patient develops intolerable toxicity. However, in some cases, if the patient's condition is under control, he may be recommended to stop drug treatment or reduce the drug dose. The dosage regimen of aflibercept is also different and needs to be adjusted according to the patient's specific situation.
