Bone marrow suppression risk identification are the important issues that need to be solved in the tumor radiation and chemotherapy treatment. This paper reviewed the research status of the correlation between radiotherapy and chemotherapy and bone marrow suppression in pelvic tumors at home and abroad from the aspects of radiotherapy technology, radiotherapy dosimetry parameters, chemotherapy regimens and so on. We aimed to provide reference for the construction of a prediction model of bone marrow suppression in our country, in order to identify high-risk groups early, formulate prevention and treatment.
