Abstract： Myelosuppression is one of the most common and serious adverse reactions after chemotherapy in cancer patients.As a tool of assessment,screening and prediction,the risk prediction models of myelosuppression can help medical staff identify high-risk groups of myelosuppression at early stage.This study integrated the risk factors of my-elosuppression of cancer patients after chemotherapy,and summed up the risk prediction models for myelosuppres-sion.The construction methods,verification techniques,and predictive performance of various models were compared here,and their shortcomings were also analyzed.It provided reference for early identification of high-risk groups of myelosuppression and timely effective preventive measures.
